Abstract

This study aims to analyze the ICN Kerinci Coffee Perfume agroindustry. Data collected from June 2019 to August 2019 were analyzed using the descriptive analysis to describe the business profile and quantitative analysis using the variable costing approach to explore profit and breakeven point. The results showed that the ICN Kerinci coffee perfume business is a medium-scale business with ten workers, including business owners as leaders who concurrently marketers and wives as administrative and financial staff. In fulfilling raw materials in green beans from the Robusta type, business owners collaborate with partner farmers. At the time of research, ICN Kerinci only produced one kind of product with two packaging variants, namely Kerinci original perfume for Rp.22,000/pack (45 grams) and an original variant + oil coffee (package) for Rp.35,000/pack. The study suggested expanding the market, especially to Eastern Indonesia, and increasing good cooperation with farmers to ensure the certainty of supply of raw materials; and provide prices based on sorting and grading to stimulate farmers to improve the quality of their green bean products.

Abstract

The medicinal properties of Pouteria campechiana fruit in Vietnam currently have not been studied much. This study was conducted to evaluate hydrolysis's effect on the carotenoid, tannin, and antioxidant activity through the correlation between IC50 and TPC values of Pouteria campechiana extract. This study examined hydrolysis conditions, such as enzyme type, enzyme concentration, temperature, and hydrolysis time. Experimental results showed that at pectinase enzyme concentration of 0.6 wt%, cellulase enzyme concentration of 0.6 wt%, at hydrolysis temperature of 600C, and 65 minutes for hydrolysis, the study found carotenoid of 115.14±4.14 (µg/g) and tannin of 45.88±2.37 (mgTAE/g)in the extract. IC50 value (7.82±0.21 mg/mL) and TPC content were highly correlated (R2=0.98). This study's results contributed to the provision of valuable scientific data on Pouteria campechiana fruit, especially for the food industry

Abstract

This study has been conceived with the basic objective to investigate the role played by industries in the East Godavari River Estuarine Ecosystem (EGREE) region to reduce the level of industrial pollution and other eco-friendly initiatives taken for eco-friendly and sustainable development. Effluent treatment systems prevalent in the majority of the studied industries are in working conditions. 57% of industries' effluent treatment plants are working conditions, 29% of the industries are using landing filling methods for disposal of agro-based waste. There is a strong common understanding among the EGREE region industries to lower the CO2 footprint by substituting coal consumption with bio-fuel. In some companies like ITC, biofuel consumption is 80%, and the remaining 20% is Coal. Government and policymakers have to make provision for industrial waste disposal, especially for small and medium enterprises (SME).  Waste transporting cost is high for SME. Effluent treatment plant (ETP) and sewage treatment plant (STP) conditions to be verified by the pollution control board periodically

Abstract

Rice is staple grain production that plays an important role in food security and the socio-economic value of agriculture in South East Asia countries. Among the factors that have negative effects on rice, weed is the major one. Its production constraint is directly seeded rice; besides, weed also affects rice growth and yield by competition about light, water, nutrient, space. Jussiaea octovalvis is a kind of weed in the field during rice growth to mature, which affects the growth and yield of rice but not significantly different based on this research. Treatments were arranged factorially in Randomized Block Design (RCBD) with two factors, 20 treatments (4 varieties, 5 of weed densities), and four replications, and each repetition used two pots for each treatment. As a result, the data showed the difference between the rate of growth and the yield of rice grain recovery products. Especially at data of LL 58 DAP showed significant difference (P=0.017), which the highest rate is 59.13 cm of V2; for harvest data showed that V3 is the best result, but it is also a sensitive one in the condition of weed densities impaction more than the others varieties (D0V3=620.5; D4V3=438). Besides, the measurement of W1000 of rice grain (30.96 g) and Wt per pot (20.01 g) of D0V3 is weight more than the other treatment; within D4V4 was obtained lowest of W1000 (19.26 g) and the lowest of Wt is D1V1 (5.25 g). Besides that, D2 and D4 are more effective on rice growth and yield, and it was non–significant. However, it is not the interaction between weed densities and varieties of rice.

Abstract

This research is motivated by the condition of Gambier marketing in Limapuluh Kota Regency, the Gambier center of West Sumatera and Indonesia, which is still experiencing problems and tends to be inefficient because of the high marketing margins, and the low share received by farmers. This study aims to analyze what factors influence the marketing efficiency of Gambier commodities in Lima Puluh Kota Regency. In this study, the researcher uses a Structural Equation Model (SEM) PLS method by taking 100 Gambier producers from Kapur IX sub-district and Pangkalan Koto Baru sub-district as research sites. The results showed that the variables of human resources, marketing institutions, products, capital, and markets significantly affect the marketing efficiency of Gambier commodities in the research site. Only the variable of government policy did not have a substantial impact on marketing efficiency

Abstract

This study analyzes the factors influencing gambier productivity, analyzes the technical efficiency of gambier farming, and analyzes the factors affecting gambier farming's technical efficiency. This research was conducted in Lima Puluh Kota Regency, a gambier production center in West Sumatra. Data were analyzed using the Cobb Douglas stochastic frontier production function. The results showed that the factors that significantly influenced gambier's productivity were labor, NPK fertilizer, plant age, number of trees, varieties, and technology. The number of labor, fertilizer factor, plant age, number of trees, and seedling varieties had a positive effect on gambier productivity. In contrast, NPK fertilizer and technology had a negative impact on gambier productivity. The technical efficiency level of gambier farming started from 0.25 to 0.99 with an average level of 0.76. It means that farmers are technically efficient but can still increase gambier productivity if they use production inputs appropriately and adequately. Factors that significantly influence technical efficiency are age, farming experience, and technology. Older farmers will have a higher level of technical efficiency compared to young age. The lower the farming experience, the more technically efficient the farmer is. Farmers who use the hydraulic jack system technology are more efficient than farmers who use the jack system technology
