Peningkatan Kapasitas Kelompoktani Melalui Inovasi Teknologi Pembuatan Pupuk Organik Di Kecamatan Janapria Kabupaten Lombok Tengah

During 2013-2019, rice production and cattle population in West Nusa Tenggara Province increased, however, rice productivity tended to decrease. One of the reasons for this decline in rice productivity is the excessive and continuous use of chemical fertilizers, which causes the soil structure to harden. Therefore, it is necessary to develop the use of non-chemical fertilizers or organic fertilizers whose raw materials come from cow dung which is often found in the field. Apart from that, animal feed, especially cows, is actually available around the community, namely in the form of forage from plants. However, management of forage for livestock has not been carried out by many farmers. Based on these problems, this community service activity aims to increase the capacity of farmer-livestock groups to be able to apply technology for making organic fertilizer and feed management. This community service activity was carried out in Saba Village, Janapria District, Central Lombok Regency, where there is quite a lot of agricultural waste potential available. Implementation of activities includes: outreach, Focus Group Discussion (FGD), training, and practice in making organic fertilizer and managing animal feed. The target of the activity was 30 members of the farmer-livestock group in Janapria District. The output of the activity is increasing farmers' knowledge, skills and attitudes in organic fertilizer production technology; as well as the production of solid organic fertilizer (compost), liquid organic fertilizer and animal feed from agricultural waste. Output in the academic aspect is in the form of writing in journals or seminar proceedings. The evaluation results using statistical methods with paired sample t tests in this activity showed that there was a significant increase in farmer-breeder behavior after participating in training activities in making organic fertilizer and making feed. Some farmer-breeders have implemented the results of the training and feel that there are savings in farming costs by using organic fertilizer that they make themselves

THE IMPACT OF ORGANIC FERTILIZER FROM TEMBANG FISH (Sardinella fimbriata) AND COCONUT WATER (Cocos nucifera L) ON THE GROWTH AND FRUIT OF BIRD’S EYE CHILI PLANTS (Capsicum frutescens L.)

AbstractThis research aims to determine the impact of administering varying quantities of liquid organic fertilizer obtained from tembang fish (Sardinella fimbriata) and coconut water (Cocos nucifera L) on the development and productivity of bird's eye chili plants (Capsicum frutescens L). This study was carried out in North Penajam Paser Regency from April to July 2023. This study employs a quantitative research methodology using a randomized factorial group (RAKF) design. The design has 2 factors, each with 16 treatments, and is replicated 4 times. The measured variables consist of plant height (in centimeters), leaf count (in strands), and fresh fruit weight (in grams). The results showed that treatment P2 (25 mL POC coconut water) had a real influence on the height parameters of bird's eye chili plants. Treatment P2 showed the highest average at the age of 70 and 79 HST, namely 44 cm and 45.5 cm. Meanwhile, treatment P16 (35 mL POC of tembang fish and 75 mL POC of coconut water) results demonstrate a notable influence on the parameters of leaf number and fresh fruit weight. The P16 treatment showed the highest average number of leaves at 56, 70 and 79 HST, namely 229, 245.75 and 326 strands. Furthermore, P16 treatment produced the highest average fresh fruit weight, namely 29 grams

Effect of spent engine oil pollution and liquid organic fertilizer application on soil chemical properties and nutrient contents of Maize (Zea Mays)

A trial was conducted to evaluate the effect of spent engine oil (SEO), bio-treated with liquid organic fertilizer, on maize plant growth. The study utilized three concentrations of SEO (0.5 and 10% w/w) and four liquid organic fertilizers (water control, cattle dung, poultry manure and rabbit manure). These factors were arranged in a 3 × 4 factorial setup with three replications in a completely randomized design. Collected data included percentage moisture, dry weight, nutrient content and uptake, heavy metal concentration, and post-harvest soil chemical properties. Soil composite samples on physical and chemical analysis carried out show that the engine oil pollution negatively affected soil pH, total nitrogen, available phosphorus, and exchangeable cations, but it increased total organic carbon before maize cultivation. The percentage moisture and dry weight of the maize plant were not significantly (p > 0.5) influenced by engine oil pollution or liquid organic fertilizer application. N, P and Mg content of maize plant were significantly reduced by the engine oil pollution but significantly boosted by organic fertilizer application. Cr and Pb content of the maize were increased with engine oil concentration but decreased with liquid organic fertilizer. Nutrient uptake was decreased with increase in engine oil content but increased with liquid organic fertilizer application. At the end of the experiment, engine oil pollution significantly depressed pH, total N, available P and exchangeable cations, but increased organic C, total hydrocarbon, exchangeable Al and heavy metal content while it was opposite for liquid organic fertilizer. Our findings suggested that soils polluted with SEO should be corrected with the application of organic fertilizers.

An Incubation System for the Simulation of Ammonia Emissions from Soil Surface-Applied Slurry: Effect of pH and Acid Type

Acidification of slurry is a promising approach for reducing ammonia emissions during the application procedure. Since only a few studies have been conducted focusing on ammonia emissions during the application of liquid organic fertilizers on the soil surface, a suitable incubation system was developed to evaluate the effects of acidification under controlled conditions. This incubation system was used to measure the ammonia emissions of various liquid organic fertilizers. The substrates were acidified with sulfuric and citric acid to different pH values to determine both the influence of the pH value of the substrates and of the type of acid on the ammonia emissions. The emissions decreased with declining pH value, and the reduction in emissions compared to the initial pH of the substrate was over 86% for pH 6.5 and over 98% for pH 6.0 and below. At the same pH value, the ammonia emissions did not differ between substrates acidified with citric acid and sulfuric acid, although more than twice as much 50% citric acid was required compared to 96% sulfuric acid to achieve the same pH value. Overall, our results demonstrate that the incubation system used is suitable for measuring ammonia emissions from surface-applied liquid organic fertilizers. The system allows for the differentiation of emission levels at various pH levels and is therefore suitable for testing the effectiveness of additives for reducing ammonia emissions from liquid organic fertilizers.

The research was carried out at Research and Educational Garden of the STIPER Agricultural Institute which is located in Maguwoharjo, Sleman, Yogyakarta Special Region, Indonesia. This experiment was conducted from April – July 2023. This research design used a factorial experiment arranged in a completely randomized design (CRD) consisting of two factors. The first factor was the composition of the planting medium with 3 kinds, namely: M1 = top soil + cocopeat (1:1); M2 = top soil + husk charcoal (1:1) and M3 = top soil + cocopeat + husk charcoal (1:1:1 ). The second factor was the LOF of vegetable waste which consists of 4 kinds, namely: P0 = without LOF (Liquid Organic Fertilizer) of vegetable waste (control); P1 = 50 ml / plant; P2 = 80 ml /plant and P3 = 100 ml / plant. The treatment combinations were 3 x 4 = 12 with 4 replications to obtain 48 plants. Data observations were analyzed by using analysis of variance (ANOVA) and if there were significantly differences, it was continued analyzed with the Duncan's Multiple Range Test at 5%. There is an interaction between the composition of the planting medium and the LOF of vegetable waste, on the fresh weight of the crown and the fresh weight of the roots. The best treatment combination for crown fresh weight and root fresh weight is top soil + husk charcoal with vegetable waste LOF 100 ml/plant. The composition of the planting media has an influence on planting height, number of leaves, fresh weight of the crown and fresh weight of the roots. Top soil + charcoal husk planting media is the best. The LOF concentration of vegetable waste has an effect on stem diameter, fresh weight of the crown and the roots. Giving vegetable waste LOF of 50 ml/plant and so on up to 100 ml/plant shows better growth.

The highest average value for number of leaves is 30.00, while the highest average value for height is 39.60, the highest average value of 3.35 for leaf area index, and the highest average for leaf area index. 4.0 for number of branches.

Analysis of the heavy metals and Escherichia coli contamination of liquid organic fertilizers in the local market, Sri Lanka

Commercially available liquid organic fertilizers have gained popularity in agriculture due to their convenience and perceived environmental benefits. However, these fertilizers are susceptible to various contaminations, including heavy metals such as lead (Pb) and cadmium (Cd), as well as bacterial contaminants like Escherichia coli (E. coli). Monitoring these contaminants helps to identify potential health risks to consumers, prevent soil and water pollution, and maintain the quality of agricultural products. Therefore, this study involved a comprehensive analysis of Pb and Cd heavy metals and E. coli bacterial contaminants in two widely used liquid organic fertilizers in the local market. The samples were digested using an open-vessel acid digestion followed by the flame atomic absorption spectroscopic (FAAS) analysis. The limit of detection (LOD), limit of quantification (LOQ), matrix effect, and spike recovery were determined. The Pb concentration of one fertilizer was 3.45 (± 0.07) mg/kg with 92% recovery whereas the other was 2.87 (± 0.08) mg/kg with 91% recovery. In contrast, the Cd concentration was 0.09 (± 0.01) mg/kg and 0.11 (± 0.01) mg/kg with percentage recoveries of 93% and 90% for two fertilizers respectively. The Pb content exceeded the maximum permissible limit of 1.0 mg/kg set by the Sri Lanka Standard (SLS 1702:2121), while Cd levels remained within the limit of 0.5 mg/kg. Polymerase chain reaction (PCR) coupled with gel electrophoresis confirmed the presence of the pathogenic O157:H7 E. coli strain in both fertilizers. Thus, the results of this study confirmed the lead (Pb) and Escherichia coli contamination in liquid organic fertilizers in the local market of Sri Lanka.

Influences of pH control in the organic liquid fertilizer production using MASARO technology

Indonesia’s food security compels the government to develop food and land intensification as a long-term national program. It cannot be denied that food productivity is closely related to fertilizer demand considering that Indonesia is an agricultural country. However, to date, 86.5% of Indonesian farmers rely on synthetic fertilizers which are adverse to the environment. On the other hand, Indonesia is the 2nd largest food waste producer and most of them are still unprocessed. Therefore, a practical solution to overcome this problem is to offer the application of MASARO technology. This technology can convert 1 kg of degradable waste into 10 L of organic liquid fertilizer so that it can increase agricultural productivity while replacing the role of synthetic fertilizers. In the organic liquid fertilizer production process, pH is an important parameter of the entire fermentation process where the value should be in the range of 3.9-4.2. However, the manual process still requires a long production duration, 28 days, because of pH value overshoot. By implementing a pH control system, the duration of organic liquid fertilizer production can be cut by 57% (from 672.8 hours to 288.6 hours) so the effect is proven can provide optimal and effective fermentation.

Organic fertilizers are defined as fertilizers derived from plants or animals that have gone through an engineering process to improve soil biological, physical, and chemical properties. Organic fertilizers in this study were made from basic ingredients in the form of waste banana peels and pineapple peels. Pineapple and banana peels are often found in the form of waste from food and beverage processing facilities that are collected and not used. Therefore, in this study we made liquid organic fertilizer (POC) from banana and pineapple peel waste. The purpose of this study was to examine the quality of liquid organic fertilizer (POC) products with parameters of pH, temperature, and C-Organic content compared with quality standards according to the Decree of the Minister of Agriculture of the Republic of Indonesia No. 261 / KPTS / SR.310 / M / 4/ 2019 concerning Minimum Technical Requirements for Organic Fertilizers, Biological Fertilizers and Soil Improvements. The production of POC in this study was carried out using the anaerobic method, where the fermentation process itself was carried out for 14 days using Effective Microorganisms (EM4) as a bioactivator. The results of this study indicate that the highest temperature in POC made from banana peels was obtained during the initial fermentation time of 33 oC and the lowest temperature was obtained during the 3-day fermentation time of 25 oC, while in POC made from pineapple peel, the highest temperature was obtained during the initial fermentation time. of 33.5 oC and the lowest temperature was obtained during the 9-day fermentation time of 26 oC. The initial pH value for POC made from banana peels is 5 and the final pH is 4. While for POC pineapple peel, the initial pH value is 3 and the final pH is 4. For the C-Organic content in the initial POC peel the results are 0.095% and final C-Organic content of 0.021%. Meanwhile, the initial C-Organic content in the POC of pineapple peel was 0.037% and the final C-Organic content was 0.013%. The final value of the pH parameter is in accordance with the quality standard, which is 4-9 for pH, while the final value of the C-Organic parameter is not in accordance with the quality standard where the C-Organic content according to the quality standard is a minimum of 10%.
