Health and Production Performance of Broiler strain Cobb with Closed House IoT system in Cimahpar, Bogor

One source of affordable protein for the Indonesian was broiler chickens. Farmer were competing to do optimal broiler production. For independent farmers, it is difficult to carry out efficient production because of global warming which triggers rapidly changing microclimate condition. Therefore, the closed house system can be an alternative. The purpose of this study was to observe the performance of strain cobb broilers reared in a closed house system supported by the Internet of Things (IoT). A total of 12,000 DOC were divided into 2 types of cages and 2 maintenance periods. The types of cages used were closed and open house and the maintenance period was January-February and April-May 2022. Each cage contain of 3,000 individuals and were maintained with a standard system. IoT systems were used to monitor the microclimate conditions. The results of the recording show that the closed house system gives better results. The comparison of the average body weight per chicken between closed and open house on days 4, 15, 25, and 30 respectively was 88 and 86 g; 520 and 495 gr; 1.73 gr and 1.127; 1,630 and 1,520 gr. The total harvest weight gave an increase of 5.21% (4,259 to 4,481.8 kg) and a better FCR from 1.49 to 1.40 in the closed house system. The closed house system for independent farmer was able to increase the efficiency because it provides comfortable microclimate so that the chickens grow better. The independent farmers can use closed house system for more profitable broiler production.

Demonstrating Agroecological Practices in Potato Production with Conservation Tillage and Pseudomonas spp., Azotobacter spp., Bacillus spp. Bacterial Inoculants—Evidence from Hungary

This study explores agroecological practices designed to improve soil quality and crop yield in small-scale agriculture, focusing on soil inoculation with beneficial bacteria over conventional fertilizers. Conducted at the SZIA Agroecological Garden MATE in Gödöllő, Hungary, the research utilizes 12 plots to evaluate different conservation tillage methods, including minimum and no-tillage, with and without microbial inoculation. Commenced in 2022, this study centers on potato cultivation (Solanum tuberosum L.) and includes comprehensive chemical and physical analyses of soil and harvested potatoes, alongside continuous monitoring of growth. Statistical analysis using One-way Anova in R revealed p-values predominantly above 0.05, indicating no significant differences across most parameters, though variations in soil plasticity and pH (KCl) were noted. Results suggest that substantial treatmeent differences may require a longer observation period. Notably, plots with microbial inoculation exhibited higher harvest weights and tuber sizes compared to control plots. Additionally, trends and interactions were found between weed abundance, total harvest, and plant height. The findings indicate that the benefits of integrated agroecological practices, including conservation tillage, may take time to materialize, emphasizing the necessity for extended observation. This research lays the groundwork for future studies, underscoring the importance of patience in achieving improvements in soil health and crop quality through sustainable agricultural methods.

Water Spinach (Ipomoea reptans Poir) Hydroponic Kratky System at Various Levels of PbSO4 Contamination

Lead (Pb) contamination and types of nutrients in static hydroponic system for growing water spinach are increasingly being studied due to the impact on the food chain. Consequently, the presence of Pb needs to be considered, specifically in fast-growing plant commodities. Alternative nutrient sources that are cheaper and more easily available should be developed and tested for effectiveness in the Kratky hydroponic system. In general, the Kratky hydroponic system runs without electricity and does not use wicks, making it economical and easy to apply in urban agriculture. Therefore, this research aimed to determine the effect of nutrition type and Pb absorption on the growth of water spinach planted in the Kratky hydroponic system. Test plants were planted for 30 days and the research used a 2-factor factorial randomized block design. The Pb concentration was varied at 50 , 100, 150, and 200 mg/L. The plant without Pb was used as control. The nutrition types used were standard hydrophonic (N1) and alternative nutrients containing NPK and Gandasil D (N2). The results showed that nutrition type had a significant effect on plant height, number of leaves, root length, wet and dry weight of shoots and roots, leaf area, shoot root ratio, harvest weight and stem diameter. The ABmix nutrient type (standard hydroponic media) has better performance than alternative nutrient types. There was no growth disturbance due to Pb contamination in the form of PbSO4 . Furthermore, the combination of Pb concentration and nutrient-type treatment did not have a significant effect on the plant’s growth and production except for the number of leaves. The combination of Pb concentration of 50 mg. L-1 and AB mix nutrition provided the best number of leaves.

The effect of dosage of vermicompost and biourine plus on growth and yield of organic shallot (Allium ascalonicum L.)

Shallot is a common horticultural crop, providing a number of benefits. Effect of organic manure and liquid organic fertilizer and their interaction on growth and yield of shallot was studied. The purpose of this study was to determine the effectiveness increase organic shallot yield with dose fertilizer vermicompost and biourine plus. A two factor experiment with three replications, arranged in factorial randomized block design, was carried out. First factor was dose of vermicompost i.e without vermicompost, vermicompost 10 t/ha, vermicompost 15 t/ha. Second factor was dose of biourine Plus i.e without biourine plus, biourine plus 1500 l/ha, biourine plus 2000 l/ha. Observed variables were height plants, numbers of leaves, number of tubers, fresh weight of tuber, and dry tuber weight. Data were analysed by F test followed by LSD at 5%. It was concluded that the vermicompost and biourine plus dose treatment produced a significant impact on plant height and number of shallot leaves but had no effect on shallot yields. Vermicompost 15 t/ha is able to increase the harvest weight of shallots (fresh weight) by 14% and increase the dry weight of tubers by 17.45%.

Growth and production of Pakcoy plant (Brassica rapa L.) by giving NPK fertilizers and biosaka

Abstract Optimizing in using agricultural production materials is important to be paid attention to in order to support food security and global climate change. The progressive application NPK fertilizer application can also increase growth and vegetable yields, supported by the application of biosaka which is a plant extract liquid containing low levels of phytohormones and secondary metabolites. Its function is to stimulate plant growth and increase plant resistance to pests and diseases. This research studied the growth and production of Pakcoy (Brassica rapa L.) by applying NPK fertilizer and biosaka, held in Medan, at ± 25 meters asl, from December 2023 to January 2024, using a Randomized Block Design with two factors and repeated 3 times. The first was the application of NPK 16:16:16 fertilizer (150; 200; 250 kg/ha). The second was biosaka solution concentration (0.67; 1.33; 2.00 ml/L). The application of NPK fertilizer had a real impact on plant height, leaves number, fresh shoots weight and harvest weight with the best NPK fertilizer dose of 150 kg/ha, but had no real effect on harvest index. The application of biosaka and interaction or both treatments have not real impact to all parameter’s.

Pendampingan Pembuatan dan Aplikasi Herbal Probiotik untuk Budidaya Ikan Lele pada Pokdakan RSB Fisheries Family

The regional and national governments want fish farming to boost the community's income. A tarpaulin tank catfish farming demonstration plot was provided by the Indonesian Ministry of Maritime Affairs and Fisheries to Pokdakan RSB Fisheries Family. Freshly stocked catfish seeds died 100% during growing. Mulawarman University trains and assists Pokdakan in using probiotic herbs to promote catfish seed resilience and growth. On March 23–24, 2024, the Pokdakan Cultivation Pond will host this event. The program begins with an introduction to herbal medicine and fish probiotics, then covers how to create them, how to use them in catfish farming, and survival and growth monitoring. The exercise involved 10 Pokdakan members. This course helps Pokdakan freshwater fish farmers understand the varieties and benefits of herbs and probiotics, their dosage and how to soak and combine them with feed, and how to monitor and diagnose early sickness in catfish fry. Following 2.5 months of maintenance, this activity reduces seed mortality from 100% to 20%, yielding an average harvest weight of 100 g/head.

Fish production, water quality, and the role of nitrification as an ammonia removal process in intensively aerated hybrid catfish ponds

AbstractSix 0.1‐ha earthen ponds with 45 kW/ha of aeration capacity were stocked with hybrid catfish (Ictalurus punctatus x I. furcatus) ranging from 15,000 to 90,000 fish ha−1 in 15,000 fish ha−1 increments to analyze the effect of nitrogen loading on ammonia accumulation and fish production. Minimum dissolved oxygen (DO) concentration was maintained above 3.0 mg O2 L−1 to prevent hypoxia‐induced appetite reduction. Stocking density did not impact survival but decreased average fish harvest weight and increased food conversion ratio (FCR). Gross production increased with stocking density and ranged from 7249 to 35,674 kg ha−1. Average total (TAN) and un‐ionized ammonia (NH3) were not different among stocking densities despite greater nitrogen inputs in ponds with higher feeding rates. Nitrite () and nitrate () concentrations were significantly higher in ponds with higher stocking densities, suggesting that nitrification increased with nitrogen loading. Phytoplankton assimilation of ammonia is the primary ammonia removal process in traditional catfish ponds with modest fish densities and feeding rates. However, in intensively aerated ponds with high feeding rates, nitrification can become an important process for ammonia removal. These data indicate that small earthen hybrid catfish ponds with high aeration capacities can increase catfish production without ammonia accumulating.

Evaluation of Productivity and Financial Feasibility of Broiler Chicken Farming Business Models: Cage and Postal Systems

The growth of the human population and increased purchasing power drive greater demand for broiler meat, posing challenges for farmers to enhance their productivity and business efficiency. The development of closed-house cages offers a solution to improve production efficiency. This study compares the productivity and financial analysis between the cage and postal models. Utilizing a quantitative descriptive method, the research was conducted over a single rearing period in cages and postal setups at PT Dinamika Megatama Citra (DMC) without any specific treatment. Research parameters encompassed body weight gain, mortality, FCR, harvest weight, and Performance Index. Financial analysis was conducted using indicators such as the R/C ratio, B/C ratio, Break-Even Point (BEP), and Return on Investment (ROI). Results indicate that in cage conditions, mortality stood at 4.07%, FCR at 1.718, average weight at 2.2 kg, and Performance Index at 287.5. Meanwhile, postal cages exhibited higher mortality at 8.79%, FCR at 1.732, average weight at 2.3 kg, and Performance Index at 285.6. In financial analysis, cage systems had a BEP price of Rp 19,726/kg with a unit BEP of 40,616 kg, an R/C ratio of 1.039, a B/C ratio of 0.039, and an ROI of 3.92%. Conversely, postal cages had a BEP price of Rp 19,507/kg with a unit BEP of 39,924 kg, an R/C ratio of 1.05, a B/C ratio of 0.05, and an ROI of 5.09%.

Evaluating the growth performance of all male sex reversal and mixed ser tilapia (Oreochromis niloticus) cultured in earthen ponds in Binh Phuo province, Vietnam

The study was conducted to evaluate the growth performance, survival rate and yield of all male sex reversed and mixed sex Nile tilapia (Oreochromis niloticus) cultured in earthen ponds for 180 days. The reversed sex and mixed sex fingerlings (mean weight 7.43 ± 0.35 g) was randomly stocked in six earthen ponds (1,000 m2/pond). The stocking density maintained was 5 fish/m2. The stocked fish were fed a commercial pellet feed containing 35% crude protein. The feeding rate was adjusted according the size of fish, 5% at the beginning to 3% at harvest. Water environment parameters including dissolved oxygen (DO) (4.3 ± 0.8 mg/L), temperature (30 ± 0.7°C), NH3 (0.18 ± 0.2 mg/L), and pH (6.9 ± 0.5) were always within the appropriate range for the normal growth and development of tilapia. The growth rate of sex reversed tilapia was significantly higher (P < 0.05) than that of mixed tilapia throughout the experiment. The harvest weight and length of reversed sex tilapia were 410.5 ± 5.15 g and 25.48 ± 0.48 cm, respectively, and were significantly higher than that of mixed sex tilapia (P < 0.05). The survival rates and feed conversion ratio (FCR) of mono and mixed sex were 90.1% and 89.9%, respectively, but no significant differences were observed (P > 0.05). The relationship of fish lengths and weights expressed by power function revealed that the slope of the length weight regression lines was normal for reversed sex (2.72) and mixed sex Tilapia (2.93) with the high correlation coefficient (> 0.9). The findings of this study demonstrate that reversed sex tilapia has better growth performance compared to mixed sex tilapia. Therefore, reversed sex fingerlings should be used in commercial farming to increase tilapia production.

Pengaruh Media Tanam Campuran Serbuk Bambu dan Serbuk Kayu Terhadap Pertumbuhan dan Hasil Jamur Tiram (Pleurotus ostreatus)

Oyster mushroom is a commodity that is in high demand in the community. Oyster mushroom production in Indonesia is decreasing year after year as wood sawdust, which is often used as a media for oyster mushrooms, becomes increasingly difficult to get. Bamboo has a nutrient content similar to wood sawdust; therefore, bamboo sawdust can be utilized as a media for growing oyster mushrooms. The aim of this research was to find the best mixture of bamboo and wood sawdust for the growth and yield of oyster mushrooms (Pleurotus ostreatus). This research was carried out from July to October 2023 at Lampung State Polytechnic. This study used a randomized block design with one factor that was repeated four times. The following treatments were used: C0 = 100% wood sawdust, C1 = 90% bamboo sawdust + 10% wood sawdust, L2 = 80% bamboo sawdust + 20% wood sawdust, C3 = 70% bamboo sawdust + 30% wood sawdust, C4 = 60% bamboo sawdust + 40% wood sawdust, and C5 = 50% bamboo sawdust + 50% wood sawdust. The collected data was analyzed using analysis of variance (ANOVA) and then evaluated with LSD test at the 5% level. The results of this research were that the treatment of C5 = 50% bamboo sawdust + 50% wood sawdust gave the best results on the parameter of the mycelium growth rate, the time of the fruit body initiation (FBI), the number of hoods, the diameter of the hood, the thickness of the hood, the harvest, the harvest weight per baglog, and the total harvesting per plot.

The most effective treatment for the growth of brown oyster mushrooms ((Pleurotus cystidiosus) is P4 treatment with 25% (375 grams of Tea Dregs + 75% (1,125 grams of Swadust).

Wheat companion plants reduced aphid and flea beetle infestations in Brassica vegetable crops in a multiple-year field study in central Germany

Alternative pest control systems such as companion plants are increasingly gaining importance owing to a reduced range of available synthetic insecticides and more rigorous regulation of their use in the EU. Therefore, we evaluated the effects of Brassica vegetables grown with wheat companion plants on relevant pests, respective natural enemies and harvest weight. Six trials were conducted in white cabbage and three in Chinese cabbage between 2017 and 2021. We identified an overall aphid-regulating effect for Brevicoryne brassicae (L.) and Myzus persicae (Sulz.) (Hemiptera: Aphididae) in white cabbage and a regulating effect on flea beetles (Phyllotreta spp.) (Coleoptera: Chrysomelidae) in both tested Brassica crops. Feeding by cabbage root fly Delia radicum L. (Diptera: Anthomyiidae) larvae on white cabbage roots was not consistently affected. Natural enemies including ladybirds (Coleoptera: Coccinellidae), hoverfly larvae (Diptera: Syrphidae), spiders (Araneida), ground beetles (Coleoptera: Carabidae), and rove beetles (Coleoptera: Staphylinidae) were assessed on crop plants or in pitfall traps. The activity density of rove beetles was increased by wheat companions in both Brassica crops, while that of ground beetles was reduced in white cabbage. The weight of harvested white cabbage was reduced by wheat companions, varying between a mean reduction of 7.67% and 40.08% in different experiments. In conclusion, wheat companion plants can be an additional tool for regulating pests in Brassica vegetables. However, competition effects on crop yield and the compatibility with other cultivation aspects, e.g. crop rotation, have to be considered.

RAFT: An IoT-Based Nutrition Monitoring System for Bok Choy Hydroponics Plants

The Internet of Things (IoT) plays a crucial role in technology advancements, especially in the agricultural sector, such as hydroponics. Manual monitoring of parameters like nutrient levels, pH, and water levels in plants consumes farmers' time and energy and increases the risk of crop failure. This research aims to evaluate the effectiveness of using IoT RAFT (Remote Automated Farming Technology) system for farmers, particularly hydroponic bok choy farmers, in monitoring and controlling plant nutrient levels and the development process using waterfall as a research methodology. Parameters tested in this research include bok choy height, number of leaves, and bok choy harvest weight. We conducted this research on 14 plants for one harvesting period, then we used linear regression to determine the growth rate by calculating the slope. The results show that the plant height, the number of leaves, and harvest weight using the IoT RAFT system are 0.5897 cm/day, 0.6391 leaves/day, and 216.43 grams, respectively. We also compared the IoT RAFT system with a non-IoT bok choy growing method, and we concluded our IoT RAFT system has a better growth rate compared to the non-IoT bok choy growing method.

Genome-wide association analyses reveal genotype-by-environment interactions of growth and organ weights in gilthead seabream (Sparus aurata)

Gilthead seabream is one of the most important fish species for Mediterranean aquaculture. More than 80% of the genetically improved fingerlings of this species originate from a single country, Greece. A previous study revealed moderate genotype-by-environment (G x E) interactions for growth traits and organ weights between commercial production sites in Greece and Spain. The main objectives of this study were to identify QTLs and genes associated with growth traits and organ weights in gilthead seabream and to identify the biological processes and pathways controlling these traits under different temperature environments. For growth traits, we found fourteen genome-wide suggestive SNP effects in Spain. A strong peak between 1.97 Mb to 4.69 Mb on chromosome (chr) 22 was shared among three growth traits (harvest weight, fillet weight and thermal growth coefficient). Fourteen genome-wide suggestive SNP effects were also identified in Greece. However, none overlap with those found in Spain. Two SNPs on chr5 (chr5:5729959, chr5:2336903) and two SNPs on chr6 (chr6:1957732, chr6:3659811) were associated with all three growth traits. For organ weights, a total of 15 SNPs were associated above the suggestive threshold in Spain. Four SNPs (chr22:1966940, chr22:6094383, chr22:67838, chr15:16798259) are shared between viscera weight and liver weight, while one SNP (chr22:67838) is shared among viscera, liver and heart weight. Interestingly, three of these four SNPs (chr22:1966940, chr22:67838, and chr15:16798259) also overlap with significant SNPs associated with growth traits. None of the SNPs associated with viscera weight, liver weight and heart weight are shared with Greece. GO and KEGG functional enrichment analyses showed that light absorption and ECM-receptor interaction are significantly enriched with growth traits QTLs in Spain but not in Greece. For organ weights, response to stimulus is the most prominent process in Spain, while cell adhesion, and regulation of phosphorylation are more prominent in Greece. Genomic architectures for growth traits and organ weights differ between environments. These findings not only explain part of the G x E interactions, but also give insight into how genetics determines differences in how environmental conditions affect growth and organ weights.

Kajian Kualitas Nutrisi Pakan Terhadap Produktivitas Ayam Kampung Super di Kabupaten Lombok Timur

The aim of the study was to determine the type and nutritional quality of feed and its effect on the productivity of super kampung chickens in The East Lombok Regency. This research was conducted by collecting data from ten farmers with a minimum population of a thousand super kampung chickens in East Lombok. Parameters observed were the type of feed used, the nutritional content of the feed, feed consumption, harvest weight, and feed conversion. The data obtained are tabulated and then discussed descriptively by comparing the nutritional content, feed consumption, harvest weight, and feed conversion obtained with the Indonesian Nasional Standard (SNI). Based on the results of the research conducted all breeders who were the target of the study used complete feed. There are 6 types of complete feed that are used and come from 4 different companies, namely GM-PS, GM-1EJ, SB11, HDBR1-168LCR, 811K NEWHOPE, HDBR 161 A. The feed consumption obtained ranges from 1.5-3.15 kg with an average of 2.26 kg/head/period. Harvested weight ranged from 0.84-0.91 kg/head with an average of 0.87 kg/head with an FCR value of 2.68. The conclusion of this study is that in general the nutritional content and quality of the feed used have met the standards based on SNI, but not followed by productivity that meets the standards.

Assessing the impact of oil palm husk-derived biochar on soil characteristics and tomato yield in Okitipupa, coastal agroecosystems

Innovative technologies using biochar were certified to mitigate the impacts of climate change and soil degradation on agriculture and ensure food security. An experiment was carried out in 2022 & 2023 cropping seasons to evaluate the effectiveness of biochar application rates at 10 t/ha, 7.5 t/ha, and 5 t/ha on soil properties and yield parameters of tomato varieties. The experiment was laid out in a RCBD replicated three times. The results show that application at 10 t/ha improved and increased pH, organic carbon, total N, and available P and K. Maximum fruit number/ha (686.2) and harvest weight (3452kg) were recorded at 7.5kg/ha. In comparison, 10 t/ha had the maximum biomass (dry weight) and harvest index compared to those of the control. The rate of 7.5 kg/ha of biochar could improve the yield, nutrient efficiency, and economic benefits of open-field tomato plants. It could be recommended for managing agricultural production.

Biofloc based farming of Nile tilapia (Oreochromis niloticus) in tanks under different stocking densities

This experiment was conducted to optimize the stocking density of Nile tilapia (Oreochromis niloticus) in biofloc based farming system in tanks for a period of 90 days from 23 December to 22 March 2022 in Mohanpur upazilla, Rajshahi district, Bangladesh. The experiment was conducted in 5000 L cemented tanks (5m3) under three different of stocking densities (T1: 200 fishes/m3, T2: 150 fishes/m3 and T3: 100 fishes/m3) having three replicates each. The initial weight of fish was 11.50±0.35 g and fishes were fed (34% protein content) twice a day @ 5-3 % body weight. Among three treatments, a significantly higher (P<0.05) average daily gain (ADG) of 1.15±0.07 g with specific growth rate (SGR) of 2.44±0.09 % day-1 were recorded in T3 treatment but a significantly higher (P<0.05) average yield of 118907.70 and 114914.20 kg/ha/3 months were obtained in T1 and T2 treatment, respectively. Higher average net benefit of 1231671.90 BDT/ha/3 months and BCR of 0.12 were obtained in T2 treatment which is significantly higher (p<0.05) than T1 and T3 treatment. By an economical assessment, if the sales price is influenced by the final body weight, the reduced average harvest weight in higher stocking densities could lead to low profitability. Therefore, it is concluded that the use of intermediate stocking density, around 150 fishes/m3, has higher profitability since it produces a large proportion of harvested fish that reach high body weights, and possible high selling prices, combined with desirable biomass.

Prediction Model of Sacha Inchi Crop Development Based on Technology and Farmers’ Perception of Socio-Economic Factors

Background: The sacha inchi plant contains nutrients that are beneficial for health, cosmetics, and food products, so it has the potential to be developed economically. The development of sacha inchi involves agricultural technology, which includes the treatment of fertilizer types that need to be studied in maintaining production and productivity. Objectives: This study aims to analyze the optimal type of fertilizer treatment on crop yields and the influence of farmers’ perceptions of socio-economic factors in the development of sacha inchi plants so that an optimal sacha inchi development prediction model is formed. Methods: The partial least squares structural equation modeling (PLS-SEM) method was applied in the study to analyze the effect of perception of socio-economic factors, and the adaptive neuro-fuzzy inference system (ANFIS) method was applied to predict the optimal fertilizer treatment model. Findings: The results of the PLS-SEM analysis showed that farmers’ perceptions of sacha inchi cultivation considered economic factors at a percentage of 50.66% and social factors at a percentage of 49.33% and had a linear relationship with the economic development of sacha inchi with a value of 0.832, although simultaneously, 77.7% was influenced by economic factors and social factors, and 22.3% was influenced outside these two factors. The ANFIS prediction results reinforced the results of the analysis, which stated that fertilizer treatment based on sacha inchi plant waste in the form of seed shells produced greater harvest weight compared with goat manure fertilizer. If farmers wanted to use a combination fertilizer, the used composition was 80% sacha inchi seed shell waste and 20% goat manure fertilizer or other materials; if the used composition was otherwise, the yield tended to decrease. This research contributes to the theory of production sustainability by integrating the optimal fertilization factor as a decision support unit in the model. Practically, this study recommends the application of fertilizer from the basic ingredients of sacha inchi seed shells to create a sustainable sacha inchi processing industry that ensures production stability, strengthens the agribusiness ecosystem, and develops the economic potential of sacha inchi and reduces the operational costs of sacha inchi farming by reducing the cost of purchasing fertilizer and supporting the circular economy model.
