Abstract

Snack food is one type of product produced by extrusion technology. Generally, extruded snack products are high in carbohydrates and low in protein because the main ingredients used are ingredients with high starch content, such as corn and rice. The protein content of extruded snack products can be increased by adding high-protein ingredients such as snakehead fish. The addition of snakehead fish to snack products can affect the physical and chemical characteristics of the resulting snack. The research aimed to study the effect of the size and concentration of fish grit on the physical characteristics (hardness, fracturability, color, expansion ratio), chemical (moisture content), and hedonic of the extruded snack product with the addition of snakehead fish grit. The study used a factorial completely randomized design consisting of 2 factors, namely factor A (fish grit size) in 3 levels (10, 12, and 20 mesh) and factor B (fish grit percentage) in 2 levels, namely (10%, and 15%). ). As a comparison (control) snacks were used without the addition of fish grit. All treatments were carried out 2 times. The size and concentration of fish grit did not affect the physical characteristics of the extruded snack, either hardness, fracture, or expansion ratio, except that the color of the extruded snack was influenced by the size of the fish grit but not influenced by the concentration or interaction between the size and concentration of the fish grit. The results of the sensory analysis showed that the combination of size and concentration of fish grit did not affect the panelists' acceptance of the sensory parameters of appearance, color, aroma, and texture but did affect the taste parameters.

Abstract

Up to now, employment in rural areas is still dominated by the primary sector, namely the agricultural sector. Especially the people in Panai Hulu Subdistrict, Labuhan Batu Regency, North Sumatra, still rely on the farming sector as a livelihood as a driver of the economy and to meet the needs of family life, which has a positive impact on improving the welfare of farmers. This study aimed to analyze the economic value and feasibility based on the scale of lowland rice farming in Panai Hulu District. The research analysis method is carried out by calculating the economic value and feasibility of farming by taking into account the economic value (production costs, revenue, income) and the feasibility value (B/C and R/C). The data collection method for this research was through interviews and field observations. The results showed the economic value and feasibility by grouping the average farmer with a land area scale of 0.5–1 ha per planting season. The research resulted in a production of 3,685 kg, total revenue of Rp. 15,430,370, the value of income obtained is Rp. 10,077,410. While the feasibility value of the Benefit–Cost Ratio (B/C) is 1.9 and the Revenue/Cost Ratio (R/C) is 2.9. Farmers with a scale of land area >1 ha per planting season produce 6,812 kg of production, total revenue of Rp. 28,363,030, and the value of the income obtained is Rp. 15,564,404. The Benefit – Cost Ratio (B/C) feasibility value is 1.3, and the Revenue/Cost Ratio (R/C) is 2.3. This value shows that the farming carried out is still quite feasible and appropriate compared to the costs incurred by farmers and has a positive impact on meeting the living needs of the farmer's family.

Abstract

Sunflower is a commodity that has the potential to be developed as a raw material for producing vegetable oil because it contains high levels of vitamin E. This plant has wide adaptability and requires areas with full sun. However, only certain varieties are able to grow and develop optimally in various agroecosystems. So we need information regarding the suitability of varieties with specific conditions of a location. This study aims to obtain information about varieties that are adaptive to new openings in the highlands of Alahan Panjang, Solok Regency, West Sumatra (1,620 masl) based on growth and yields achieved. The experiment was designed using a Randomized Block Design (RAK) with 3 groups and 5 levels of treatment, namely sunflower varieties. The varieties include IPB BM 1, Ring of fire, Russian Mammoth, Hoppy Black Dye, Black Russian, and Kanigara. The varieties of Russian Mammoth, Ring of Fire, and Hopi Black Dye have better growth when viewed from their adaptability in the research location. Meanwhile, based on the weight of seeds/plant, the percentage of pithy seeds, and the weight of 100 grains the Russian mammoth variety had the best results.

Abstract

Acidic land is underutilized as agricultural land because of its lack of nutrients and minimal water content. At the same time, acid land is widespread in Indonesia. This study aimed to determine the soil texture and response of tomato plants after applying manure and humic acid from cocoa pod extract. Humic acid was extracted from cocoa pod skin compost using the Tan method, while soil texture was measured using the pipette method. The experimental design used was a randomized block design with 3 treatments of giving organic matter to acid soil, including untreated acid soil, acid soil + manure, and acid soil + manure + humic acid. The results showed that acid soil + manure treatment could reduce the sand fraction up to 53%. In addition, there was an increase in values for all growth and production parameters of tomato plants, including plant height, number of leaves, and tomato fruit weight in acid soil. The addition of manure + humic acid to acid soil can also increase tomato plants' wet weight, dry weight, and root volume.

Abstract

The duck livestock business is one of the business branches in the livestock sector which is now widely cultivated by the community. Especially in South Sulawesi, duck farming has increased over the last 5 years. This happened because the duck culinary business increased along with the increasing demand and purchasing power of the people. In the aspect of duck farming, the feed factor is one of the problems faced by farmers because the proportion of financing can reach 60-80%. To overcome this, one solution that can be done is to utilize locally available feed ingredients sustainably. Gosse (Ceratophyllum sp) is one type of aquatic plant which if its production is excessive in ponds, can harm the growth of milkfish and shrimp. Its potential is so great, that it is considered very worthy of research. This study aims to determine the potential of Gosse as feed for ducks based on the production of fresh material, dry matter, and carrying capacity based on Geographic Information System (GIS) data. The research method applied includes 4 stages, namely Geographic Information System (GIS) analysis, analysis of fresh and dry matter production, nutritional quality analysis, and production conversion to calculate carrying capacity. The results showed that the production of fresh matter reached 74.7 tons/ha/year and the production of the dry matter reached 4,482 tons/ha/year. The production of gosse in Tellumpanua Village in total reached 1,157.09 tons/year in a fresh state and 70.3674 tons//year in a dry state. Based on these data, the carrying capacity of gosse at 30%, 50%, and 70% use respectively is 270, 162, and 115 head/ha/year or 4239, 2543, and 1805 head/year.

Abstract

Southeast Sulawesi is one of the largest producers of cashew commodities in Indonesia, which has an essential meaning in the world of trade. Determination of the polymorphism of a primer is the first step in conducting genetic diversity studies to obtain genetic information about a species. This study aims to determine the polymorphic RAPD primers to be used in the analysis of the genetic diversity of cashew in three districts in Southeast Sulawesi. The study used 20 RAPD primers to amplify cashew DNA samples and obtained three RAPD primers (OPA-15, OPP-08, and OPC-11 primers) which showed polymorphic bands in the DNA samples used. The three RAPD primers obtained have the potential to be used in genetic studies of cashew originating from Southeast Sulawesi.

Abstract

The study aimed to determine the effect of adding phytobiotics derived from the skin of shallots, garlic, and bay leaves combined with Lactobacillus sp. in turkey rations on fat deposition and carcass percentage. The experimental cattle used were 80 unsex turkeys aged 3 months. The experiment was arranged in a randomized block design (RAK) with 5 treatments and 4 groups based on body weight, each containing 4 turkeys. Groups were divided based on body weight, namely K1 (400-550 g); K2 (551-700 g); K3 (701-850 g), and K4 (851-1000 g). The treatments applied were T0= Basal ration/RB; T1=RB + 0.25 g Lactobacillus sp. ; T2 = RB + 2% Phytobiotics.; T3= RB+0.25 g Lactobacillus sp.+ 2% Phytobiotics and T4= RB + 0.5 g Lactobacillus sp.+ 2% Phytobiotics. The research parameters measured included fat digestibility, the relative weight of abdominal fat, meat fat content, and carcass percentage. The data were analyzed for variance at the 5% significance level, followed by Duncan's multiple area tests with a 5% significance level. The results showed that the addition of phytobiotics combined with Lactobacillus sp. had a significant effect (P<0.05) on the decrease in fat digestibility and fat content of meat but no significant effect (P>0.05) on the relative weight of abdominal fat and carcass percentage. The addition of 2% phytobiotics combined with 0.50 g of Lactobacillus sp. can reduce turkey meat's fat digestibility and fat content but does not increase the relative weight of abdominal fat and carcass percentage.

Abstract

The 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.
