No full textFish protein hydrolyzate is breaking down proteins into simple peptides and amino acids through a hydrolysis process by enzymes, acids, or bases. This hydrolysis process uses toman fish (Channa micropellets) as an alternative to increase protein consumption and the nutritional quality of the product. It can be used as a base for natural flavor compounds. In addition, pineapple juice is added. The research was conducted in two stages: (1) making fish protein hydrolyzate powder; and (2) testing of color, organoleptik, water content, ash, protein, fat, carbohydrate, crude fiber, and glutamic acid. The results showed that giving pineapple juice 5% gave the best results for glutamic acid levels around 108.064 ppm, protein content 13.97%, fiber content 5.15%, fat content 0.44%, color 6.0, and texture 7. This study states that fish protein hydrolyzate powder with pineapple juice can be used as an alternative as a natural flavoring agent
Design Innovative Solution Model for Banking Specific Financing in Rice Commodity Agribusiness in South Sulawesi
No full textThe long history of agricultural credit schemes in Indonesia as the track record revealed was distinctively devided into (i) Pre-Social Development (1964), (ii) Socio-national Development and Collaboration (1965-1970), Completed Social Development (1970-1984), (iv) Farm Credit (1985-1999), (v) Food Security Credit (2000), (vi) Energy and Food Security Credit (2007), (vii) People Business Credit (2007 – up to recent time). Nevertheless, up to these days non of the agrcultural financing schemes that are consistantly specified to rice product commodity development. This research aimed at 1. Analyzing the obstacles hindering the distribution of the rice commodity agribusiness financing scheme specifically viewed from the collaborative side of financial institution and rice agribusiness farmers, 2. Compehensively analyzing the procedural system for distributing financing schemes implemented to rice agribusiness farmers mainly viewed from the aspects of (i) credit interest rate, (ii) credit limit, (iii) credit recipients, (iv) credit disbursement, (v) credit refund, (vi) credit refund time, and (vii) credit collateral 3. Designing an innovative solution model for banking specific financing reserved to rice commodity agribusiness farmers. The findings of this collaborative research were as follow: (1) obstcales hindering banking institutions from distributing fund to rice farmers were the credit allocation policy itself that is relatively centralized, whereas from the side of agribusiness doers seemed to derived from the weakness of finance administration system as well as the less of bankable collasteral values; (2) Financing schemes disbursement procedural system implemented by credit channelling agencies such as BRI, BNI, and other local banks did not meet with the needs and expectation of agribusiness doers, sophisticated, and too bureaucratic as well, (3) the innovative solution model for bank financing specified to rice commodity agribusiness resulted of this collaborative research was called Rice Agribusiness Credit Scheme (RACS) in which local government squeeze as both coordinator and coach

Peranan Dark Septate Endophyte dalam Budidaya Tanaman
No full textDark Septate Endophyte (DSE) is a fungus in symbiosis with the host plant and is characterized by the presence of dark pigment, insulated hyphae, and microscleretia. The effect of DSE fungi on the host plant is specific according to the fungal strain, host plant species, and environmental conditions. DSE fungi can colonize host plant roots intra and extracellularly as well as ectendomycorrhiza. In DSE colonization, sometimes it fails to form a dense mantle and hartig net, but instead, it forms melanin microscleretia. The symbiosis between DSE fungi and suitable host plants can increase plant growth, uptake of N and P elements, resistance to drought, extreme temperatures, and protect plants from plant-disturbing organisms. The increase in the uptake of N and P elements was caused by the ability of DSE fungi to produce proteolytic enzymes and phosphatases that can mineralize organic N and P so that they become available to plants. Increased resistance to drought and extreme temperatures is thought to be due to melanin hyphae which can help absorb water from the soil and produce antioxidants and protection against free radicals. In addition, some strains of DSE fungi also produce chlorine to protect plants from plant-disturbing organisms

Pertumbuhan dan Produksi Dua Jenis Sawi Menggunakan Perbedaan Nutrisi Secara Aeroponik
No full textConsumer demand for mustard needs in Indonesia is increasing. Efforts to produce mustard greens use an aeroponic system to utilize nutrients in dosage and type correctly. The study aimed to determine the proper type of nutrition for the growth and production of two mustard greens in an aeroponic system. This study used a completely randomized design with two factors. The first factor is the type of mustard which consists of two levels, namely pakcoy and pagoda. The second factor to consider is the nutrition applied at three different levels: AB mix, liquid organic fertilizer, and foliar fertilizer. Mustard greens grew and produced significantly differently when grown in an aeroponics system. Other nutrients greatly affected all observed variables, including plant height, leaf number, leaf color, root length, fresh plant weight, and dry plant weight. The use of pakcoy mustard provides the best growth and production of mustard greens compared to pagoda-type mustard. Giving AB mix nutrition to mustard greens can provide the best growth and production compared to nutrition from liquid organic fertilizers and foliar fertilizers. The AB mix nutritional treatment with pakcoy mustard produced the best results in plant height, leaf number, wet weight, dry weight, and root length. AB mix nutritional showing the best leaf color variable with pagoda mustard greens

Uji Toleransi Dua Kultivar Kedelei (Glycine max L.) Terhadap Cekaman Kekeringan dan Pengaruhnya Terhadap Komponen Hasil
No full textThe increasing population and the demand for soybean consumption in Indonesia are not comparable to soybean production, which is still low. Land conversion and changes in climate patterns that cause drought stress are also triggers for low production. Drought stress can be anticipated by using drought stress-tolerant cultivars at various growth phases. This study aimed to determine the effect of drought stress on yields and yield components of several soybean cultivars. In addition, to determine the soybean cultivars that are most resistant to drought stress. This study was arranged experimentally using a factorial (3x2) split-plot design. The main plot, namely drought stress, consisted of three levels: watering once a day, once every three days, and watering once every six days. The sub-plots were soybean cultivars with three replications consisting of 2 levels, namely Wilis and Anjasmoro cultivars. The selection of these 2 cultivars was made on purpose because farmers had easy access to seeds. Determination of drought stress-resistant cultivars using the stress tolerance index (ITC). Drought stress caused almost all yield and yield component variables to decrease, such as the number of pods, the number of seeds per pod, and the total weight of seeds. Based on the stress tolerance index (ITC), it is known that the Wilis cultivar is more tolerant to drought stress than the Anjasmoro cultivar
