Abstract

Barriers to horticulture in several developing countries, including Indonesia, include low farmer income, limited farmer knowledge, limited farmer land ownership, and weak farmer supply situations. This results in reduced profits for farmers. One way to overcome these obstacles that can be done by the Rukun Tani farmer group is to establish a partnership with PT Agri Makmur Pertiwi. This study aims to analyze the partnership pattern in cucumber hatcheries and its impact on increasing farm income. This research used descriptive qualitative and quantitative methods with a case study approach on 20 respondents who established partnerships with hatchery companies. Data were collected through questionnaires, in-depth interviews, field observations, and documentation. Data were tested using the t-test. The results show that the partnership pattern applied is a core-plasma partnership, where the core company provides production facilities, provides guidance, transportation costs, and market guarantees. The farmer group acts as a plasma that provides land, labor, agricultural tools, fertilizers, and manages cucumber farming according to the standards set by the core company. The results of the difference test show that there are differences in income before and after partnering. Income before partnering was IDR 18,053,507.5 and income after partnering was IDR 35,622,807.5.

Abstract

Chlorophyll is a green pigment that found generally in chloroplast mesofil leaf cell. Chlorophyll is a pigment that easily degredating. Chlorophyll degradation is caused by temperature, light intensity, or environment condition. To keep chlorophyll from degradation, the encapsulation methods can be applied. Encapsulation is a method to coating substrate or raw material such as pigment before applied in food system. The combination of coating is called encapsulation. Pigments need to encapsulated because to protect material from degradation when processing or storaging. This research purpose is to know the influence of different solvent concentration to chlorophyll amount in storaging prosess. The research use Complitely Randomized Design. Encapsulation methods using freeze dryer and measuring chlorophyll amount using spectrophotometre. Measurement of chlorophyll amount after extracting process and encapsulation process. Measurement of chlorophyll stability do within 4 weeks storaging and each week need to measure the chlorophyll amount and half life time calculation is to know the chlorophyll life time. In the encapsulation process there is reduction about 92,18% from 75,4907 ppm to 5,9018 ppm at 50 ml solvent concentration, 75 ml solvent concentration reduction is 92,63% from 66,0438 ppm to 4,8628 ppm and 100 ml solvent concentration reduction is 91,35% from 45,7894 ppm to 3,9567 ppm. Half life time calculation is shown that chlorohyll damaging is happen at 26 days for 50 ml solvent concentration, for 75 ml solvent concentration is happen at 39 days and for 100 ml solvent concentration is happen at 75 days after storaging process.

Abstract

Organic waste management plays a crucial role in supporting sustainable agriculture by recycling valuable resources and reducing environmental impacts. This systematic literature review explores the implementation of organic waste management strategies, including composting, vermicomposting, fermentation, and eco-friendly technologies, in developed countries such as Germany, the Netherlands, and Sweden. The review also highlights the challenges and opportunities in each country, considering technological limitations, social and cultural aspects, as well as policy and regulations. Moreover, it analyzes the implications for sustainable agriculture and provides recommendations for further research. The findings underscore the importance of integrating organic waste management into agricultural practices to enhance soil fertility, reduce greenhouse gas emissions, and promote sustainable farming systems globally.
