PROBLEM ANALYSIS IN ISLAMIC COOPERATIVE IMPLEMENTATION FOR KARANGASRI FARMER GROUP KAMPUNG DURIAN PONOROGO

Cooperatives in Indonesia is the cornerstone of the economy for all people, especially those with low economies . Agriculture in Indonesia experienced a decline in 2017. One of the problem factors is the problem of capital. To overcome the problem of capital in agriculture, the right step is the establishment of a cooperative. The cooperative will regulate the financial circulation of the farmer groups. The farmer group that is the object of this research is the Karang Asri Kamnpung Durian Ngebel farmer group. This Karang Asri farmer group is the focus of this research because it has the potential for agricultural products that are much sought after by the community, namely durian fruit. In this study, the researcher will analyze the problems that exist in the Karang Asri farmer groups in Durian Ngebel Village which are the causes for the not yet established cooperatives in the farmer groups and formulate a cooperative model that can be established in the Karang Asri farmer groups. The method used in this research is descriptive qualitative with data collection techniques through, observation, interviews, and documentation. By interviewing the head of the Karang Asri farmer group representing the entire group. The results of this study indicate that six problem sectors are ranging from human resources, natural resources, production, distribution, systems, and problems from outside the farmer group. The problems that exist are divided into two groups, namely roots and branches. The root problem is the main problem because there is no cooperative in the farmer group. T he branch problem is a factor that indirectly causes the absence of a cooperative. Then the cooperative model that was successfully designed was the sharia producer cooperative. It is hoped that this cooperative model will be a capital solution and also all problems that exist in farmer groups.

Teratogenic Effects of Durian Fruit (Durio Zibethinus Murr) on White Mice Fetus (Mus musculus L)

Durian (Durio zibethinus L.) is one of the most consumed and liked fruit in Indonesia, but there was no evidence about the safety of consuming durian during pregnancy. This study was determine the level of safety of durian fruit consumption during pregnancy by conducted teratogenicity test of durian fruit (Durio zibethinus Linn) on fetuses of white mice (Mus musculus L). Teratogenicity test was conducted in vivo, by step: preparation of experimental animal, observation during administration, laparotomy, fixation and observation of morphological defects. Data were analyzed using Analysis of Variance (ANOVA). If the results were significant (P < 0.05), the analysis was continued using Duncan Multiple Range Test. Administration durian during pregnancy did not affects the bodyweight of the mice (P > 0,05), but significantly influences the number of fetuses (P < 0,05) and its body weight (P < 0,05). Consumption of durian during pregnancy is safe in 32,5 mg / KgBW, but it has the potential teratogenic in 65 mg / KgBW and 97,5 mg/KgBW groups. Teratogen effects that were found in several fetuses were underweight, dead, hemorrhage, maternal death and there were resorption sites.

Phytochemical content and antioxidant properties of Bornean wild durian from Sabah

Borneo is the centre of diversity of the genus Durio (family: Malvaceae; local name: durian). Durian fruit is known to contain high amounts of the major bioactive compounds (as antioxidants) such as anthocyanins, carotenoids, polyphenols and flavonoids. Two types of wild durian species, namely Durio kinabaluensis Kosterm. & Soegeng (durian tupoloh) and Durio oxleyanus Griff. (durian sukang) were studied. The 80% methanolic extracts of flesh, seed and peel (mesocarp and exocarp) were analysed for antioxidant activities, total phenolic and total flavonoid content. The antioxidant activities were determined using three parameters; 2,2-diphenyl-1-picrylhydrazyl radical assay (DPPH), 2,2’-Azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) radical cation assay, and Ferric reducing antioxidant power assay (FRAP). Durio kinabaluensis mesocarp extract displayed the highest antioxidant properties and total phenolic content. The non-edible parts of both durians (seed and peel) exhibited higher phytochemical contents and antioxidant properties compared to the flesh parts. This data may contribute to the pharmaceutical applications, health benefit information of wild durians and helps in popularising the potential of these fruits in international markets and ultimately protects them from extinction.

Postharvest fungicide dips to control fruit rot of ‘Monthong’ durian (Durio zibethinus)

Fruit rot diseases are the serious problem in durian production for domestic consumption and export. Fungicides are commonly applied to reduce postharvest loss caused by postharvest diseases. The objective of this research was to study the efficacy of fungicides for controlling durian fruit rot diseases. Diseased durian cv. ‘Monthong’ were collected from three orchards from Tha Mai district, Chanthaburi province. Fungi were then isolated by tissue transplanting method and identified based on morphological characteristics. Three fungi including Fusarium solani, Lasiodiplodia theobromae, and Phomopsis sp. were confirmed as causal agents of fruit rot on durian. Ten concentrations of two ready-mix fungicides, which were Bumper P® (prochloraz 40% + propiconazole 9% W/V EC) and Custodia® (azoxystrobin 12% + tebuconazole 20% W/V SC), were evaluated towards the inhibition of the fungal growths. From in vitro experiment, both treatments could inhibit the mycelial growth at different levels. The EC50 of Bumber P® and Custodia® were 9.7–49.11 and 7.93–196.73 mg L−1 and respectively. In vivo experiments by dipping fruits showed that Bumper P® and/or Custodia® at the minimum rate of 1 ml L−1 exhibited strong control durian fruit rot caused by F. solani and Phomopsis sp., but both fungicide mixtures could not control L. theobromae. The results of residue analysis illustrated that no residues were detected in the edible pulp. This is important to ensure that the treated durian is safe for consumptions and these fungicides are suitable for the postharvest application in durian.

Pl/sql design to determine the training data pattern on the Adaline neural network

Inventories of goods in business activities greatly affect the smooth running of business activities. The durian fruit sales business is also affected by inventory. Durian fruit sellers must be able to predict the needs of durian fruit customers so that sales business activities run stable. For sellers with low durian fruit sales, they will have no difficulty predicting demand for durian fruit. But for sellers of durian fruit in large quantities, it will take a long time and is prone to errors. An error in the prediction causes the sales business to lose. It takes high accuracy and fast time to make predictions. Adaline neural network has been proven to be able to solve prediction problems precisely. Adaline network performance is affected by training data. Durian fruit sales data is used as network training data to improve network performance. The focus of this research is the design of the pl/sql database to determine the training data input pattern in the android application to predict the number of durian fruit customer needs. Types of pl/sql used in this study are procedures and functions. Meanwhile, the method used to design pl/sql is an extreme method.

Characteristics and community perception on mitigation of Human-Tapanuli Orangutans conflict around Dolok Sipirok Natural Reserve, South Tapanuli

The frequency of human-tapanuli orangutan (Pongo tapanuliensis) conflict has been increased with the widespread on degradation and fragmentation at Batangtoru Forest, South Tapanuli Regency. Orangutans often come on community lands to look for food, especially while the durian fruit season. This study aims to obtain information on socio-economic characteristics and public perception index to mitigate on human-tapanuli orangutan conflict around the Dolok Sipirok Nature Reserve, South Tapanuli Regency. Data was collected using a questionnaire distribution, interviews and descriptive observations, starting from October 2019 to January 2020. Respondents were selected by purposively sampling method, i.e. people had met and interacted with orangutans as many as 61 respondents from three villages. Data analyzed using frequency tables, likers scale and spearman rank correlation. The results showed that the community is Muslim majority, productive age, education below senior high school, farmers and income below IDR. 4,000,000. The public perception has declared orangutans as animals that consume community plants. They will drive away the orangutans found in processed land. The perception of conflict mitigation has strongly agreed with the program that must be done including providing compensation for losses, increasing patrol programs, developing local wisdom and building corridors in state forests. The characteristics were a significant (α <0.01) influence on the perception index assessment i.e. the level of education, household member and family income.

ANALISIS KLASTER DURIAN (Durio zibethinus Murr.) UNGGUL LOKAL DI KABUPATEN JEMBER DAN BANYUWANGI

Indonesia is one of the centers of durian diversity in the world and one of the regions that makes durian a superior local fruit crop is Jember and Banyuwangi. Clustering is useful to facilitate the search for certain features of the type of durian. This study aims to determine the durian grouping in two districts namely Jember and Banyuwangi. The materials used were local superior durian fruit and characterization questionnaire. Research using descriptive methods. Characterization data will be analyzed using NTSYS software.The results showed that local superior durian fruit were grouped into 2 groups based on morphological characters. Cluster 1 consists of 4 durians namely Klemben, Hijau, Bajul, and Lambau. Cluster 2 only consists of durian Musang King. Based on the chemical content of durian fruit, durian Lambau from Jember has the highest water content of 75.52%, Musang King from Banyuwangi has a fat content (2.29%), Bajul from Jember has the highest fiber content (11.89%), and Hijau from Banyuwangi has the highest protein (3.14%) and sugar (26.08%) content. Based on PCA showed that Musang King and Hijau have similirity on some morphological characters and chemical fruit contents. The results of correlation analysis of morphological characters and chemical content of durian fruit showed that leaf length was positively correlated with leaf width and protein content. Leaf width is positively correlated with sugar content. Fruit weight is positively correlated with water content.

Morphological Characters of Local Origin Durian (Durio zibethinus Murr.) Fruits and Seeds from Central Tapanuli Regency, North Sumatra, Indonesia

Most of the diversity resource of durian was reported existing in Central Tapanuli. Due to local durian potential, germplasm needed to obtain information on the potential for superior cultivars. Here, we report our identification of morphology characteristics to the genetic relationship of local durian to determine the best durian. This research applied exploration study, interviews, descriptive, and qualitative identification. Research data were grouped based on similarity values using cluster analysis. Results showed that each local durian from Central Tapanuli had similar morphological characters, especially in the vegetative phase. Characters that show distant genetic relationships are fruit length, fruit diameter and seed weight. Other characters that depict close genetic relationship were the color of the fruit stalks and thorns' presence in the fruit. Based on morphological characteristics, a dendrogram was drawn and formed into three clusters. The present study shows that 75 accessions of durian fruit detected in each location have a relatively close similarity distance. That similarity between durian accessions is influenced by interactions between genetic factors and the environment. This result can also be used for durian conservation aimed at collections as genetic resources to benefit durian breeding in expanding diversity.

Fruit ripening-associated leucylaminopeptidase with cysteinylglycine dipeptidase activity from durian suggests its involvement in glutathione recycling

BackgroundDurian (Durio zibethinus L.) is a highly popular fruit in Thailand and several other Southeast Asian countries. It is abundant in essential nutrients and sulphur-containing compounds such as glutathione (GSH) and γ-glutamylcysteine (γ-EC). Cysteinylglycine (Cys-Gly) is produced by GSH catabolism and occurs in durian fruit pulp. Cysteine (Cys) is a precursor of sulphur-containing volatiles generated during fruit ripening. The aforementioned substances contribute to the strong odour and flavour of the ripe fruit. However, the genes encoding plant Cys-Gly dipeptidases are unknown. The aim of this study was to measure leucylaminopeptidase (LAP) activity in durian fruit pulp.ResultsWe identified DzLAP1 and DzLAP2, which the former was highly expressed in the fruit pulp. DzLAP1 was expressed at various ripening stages and in response to ethephon/1-MCP treatment. Hence, DzLAP1 is active at the early stages of fruit ripening. DzLAP1 is a metalloenzyme ~ 63 kDa in size. It is activated by Mg2+ or Mn2+ and, like other LAPs, its optimal alkaline pH is 9.5. Kinetic studies revealed that DzLAP1 has Km = 1.62 mM for its preferred substrate Cys-Gly. DzLAP1-GFP was localised to the cytosol and targeted the plastids. In planta Cys-Gly hydrolysis was confirmed for Nicotiana benthamiana leaves co-infiltrated with Cys-Gly and expressing DzLAP1.ConclusionsDzLAP1 has Cys-Gly dipeptidase activity in the γ-glutamyl cycle. The present study revealed that the LAPs account for the high sulphur-containing compound levels identified in fully ripened durian fruit pulp.

The analysis was designed to observe the microbial consortium associated with solid state fermentation (SSF) for amylase production. Together with the additional data from culture-dependent analysis, we observed the morphological features, molecular characteristics, and amylase concentration produced by each isolate. We performed Solid State Fermentation (SSF) for amylase production and the enzyme activity was then determined using UV-Vis spectrophotometer at 540 nm. Result obtained from metagenomic approach consist of 4 group that fungal species included in the Ascomycota identified as Botryosphaeria dothidea (1.35%), Lasiodiplodia crassispora (17.62%), Aureobasidium pullulans (55.02%), Paraphoma chrysanthemicola (11.38%), Preussia funiculate (1.90%), Sporormiella intermedia (0.82%), Myrothecium gramineum (1.35%), Fusarium oxysporum (6.24%), Fusarium proliferatum (3.25%) and Phialemoniopsis curvata (1.08%). The results of isolation using culturable medium in the form of YMA obtained 40 yeast isolates. A total of 40 representative isolates from durian fruit were screened, two positive amylase isolates based on clear zones formed were DU 4.2 (Candida sorboxylosa) and DU4.22 (Cyberlindnera fabianii) isolates with amylolytic index of DU 4.2 isolates at 0.24 and DU 4.22 at 0.72 with an incubation time of 48 h. The highest amylase enzyme activity was found in isolate DU 4.2 of 31.21 U / mL.

Teknologi Pengomposan Limbah Kulit Durian Menggunakan EM4

Durian rind waste is a source of organic material that is easily found during the durian fruit season in South Kalimantan, where the potential abundance can reach 100 tons / day. If left unchecked, it will involve environmental problems such as garbage build-up, strong odors, and aesthetically disturbing views, so special care needs to be taken on the organic waste. Therefore, a solution is needed to overcome this problem by using durian rind waste as raw material for composting. The purpose of this study was to study how to apply the EM4 dose to the quality of durian skin waste compost. This study used a single complete randomized design (CRD) consisting of 6 preparations: s0 (0 mL EM4 / kg material), s1 (1 mL EM4 / kg material), s2 (1.5 mL EM4 / kg material), s3 (2 mL EM4 / kg material), s4 (2.5 mL EM4 / kg material), s5 (3 mL EM4 / kg material). The results showed that what was needed in the study with the help of 1 mL EM4 / kg material (S1), where the durian skin compost was in accordance with SNI on the pH parameters namely 7.48, C-organic 16.59%, total N 1.34%, moisture content 42.54%, temperature 30oC, and compost odor test with criteria not approved rotten.

Shrink-wrap packaging extend the storage life of mature-dropped durian

ABSTRACT The shelf life of mature-dropped durian especially the premium clone Musang King (D197) is very short when store at ambient temperature without any packaging compared to other varieties. Current commercial practice is to vacuum packing the fruit using plastic material of nylon with 0.1mm thickness, helps in avoiding dehiscence up to 7 days storage. However, due to vacuum environment, there is an alteration in taste of the flesh and the core of the fruit become browning. Shrink-wrapping has potential to be used as the plastic material comes in many types and thicknesses. A study was conducted in which durian were packed in two types of packaging, vacuum-packing using nylon bag 0.1mm and shrink-wrapping using LDPE bag 0.04mm. Unpacked fruit was set as control. The quality, gas in the package and incidence of dehiscence were observed during 21 days’ storage. By shrink-wrapping the whole fruit durian, it reduced the weight loss and retained the freshness as well as the taste and overall acceptability are still accepted. The storage life of shrink-wrapped durian can be extended up to 14 days at 5°C without any dehiscence occur and maintained the fruit quality.

Effect of freeze‐dried durian skin nanofiber on the physical properties of poly(lactic acid) biocomposites

AbstractDurian skin wastes generated by durian fruit or Durio zibethinus Murray shows potential as a new natural fiber‐based reinforcement for polymers. Freeze drying (FD) method is reported able to reduce the size of particles. Thus, in this research, durian skin nanofiber (DSNF) is developed using a FD process from durian skin fiber (DSF) and its effect on poly(lactic acid) (PLA) biocomposite is investigated. Cinnamon essential oil was added as a plasticizer for PLA biocomposite. Morphological analysis via transmission electron microscopy and scanning electron microscopy showed that FD method reduced the DSF particle size into DSNF. Dynamic light scattering was also performed to see the size distribution of DSNF particle after the freeze dried process. The hydrophobicity of the biocomposite was measured by contact angle and UV transmittance was done to analyze its transparency and UV penetration. The tensile strength of these composites showed significant changes in the presence of DSF and DSNF in PLA.

Durian husk wastes as low-cost adsorbent for physical pollutants removal: groundwater supply

Durian peel can be the main contributor to agricultural wastes and becomes an environmental problem when it is discarded into the landfill site or even burning it. The average of entire durian fruit weight is about 255,353 MT for all over the country. The loading rate of landfills is increasing, especially with the massive amount and size of the durian waste that requires a larger space to dispose of. Therefore, it is certainly important to utilize durian husk as an adsorbent to improve water quality, especially groundwater source. Groundwater commonly has a higher hardness level than surface water. The higher hardness in water becomes a major concern, especially in every cleaning task. This research aimed to investigate the potential of durian husk in reducing water hardness, electrical conductivity (EC), and total dissolved solids (TDS). Durian husk was treated with NaOH solution to improve adsorption efficiency. Laboratory analyses such as the ethylenediaminetetraacetic acid (EDTA) titration method were performed for the water hardness, total dissolved solids, and conductivity concentrations respectively to test the performance of the removal efficiency before and after the treatments. As the results, the removal of hardness concentrations by durian husk has significantly dropped with dosage and settling time. However, not for TDS and EC concentrations removal, which it went sudden increased for a higher dosage. The novelty of this study is that it is the first-ever experiment using the real on-site samples in the field as for initial concentrations, different from other previous studies by lab-scale the synthetic hard water and most of them using the highest concentration of hardness which up to 700 mg/L of CaCO 3 as to find out the removal efficiency for water softening in water treatment using durian husk, compare to this study using a concentration that is too low within 300 mg/L and below.
