One alternative way to eliminate the distinctive properties of garlic is through processing, namely heat treatment which can improve the taste and create new qualities of garlic without removing the nutritional components of raw garlic, known as black garlic. However, several times there are often obstacles in fulfilling black garlic which can be produced on a large scale, does not require a long time, and is of high quality. Based on the considerations above, research was conducted on using temperature control technology to improve the quality of Asssyifa black garlic at the Utsman bin Affan Islamic boarding school. The equipment used is a thermolysis device with a capacity of 15 kg to 30 kg. This tool has a design similar to a cake-making oven but has a special rack and pan for garlic production. This research uses a survey method by looking directly at the physical characteristics of garlic processed into black garlic. Apart from that, this research also uses organoleptic tests to measure the quality of black garlic in terms of taste on the tongue. The research results, Black garlic Assyifa which is produced using a thermolysis device using the best temperature control is 70^oC for 9 days, which has a predominantly sweet taste and a blackish color.

Rice is an important food crop as the main source of carbohydrates. In Tountimomor Village, West Kakas Subdistrict, Menado, Northern Sulawesi which detection of rice production is disrupted by pest attacks. This study aims to evaluate the effectiveness of color traps in attracting insects on rice plants as an alternative environmentally friendly control. Using a Randomized Group Design (RAK) with 4 treatments (yellow, blue, red, and transparent/control traps), each trap was set on 5 plots. Trapped insects were identified in the laboratory. Results showed yellow traps were most effective with an average of 59 insects, followed by blue (42.4) and red (28.6). Color traps can be an effective and safe insect control solution in paddy plantations in Menado.

This paper provides a comprehensive overview of the results and widespread effects of the Hazelnut Gardens Rehabilitation Project in Ordu Province and the surrounding region of northeastern Türkiye. The project launched some years ago, aimed to revitalize the region's vital hazelnut industry by addressing challenges such as aging hazelnut orchards, poor agricultural practices, and environmental degradation. The paper examines the multifaceted impacts of the rehabilitation efforts through quantitative data analysis and qualitative interviews with stakeholders. Key outcomes include significant hazelnut yields and quality increases, improved soil health and water conservation, and enhanced economic opportunities for local farmers and businesses. Additionally, the study explores the ripple effects on the region's environmental sustainability, food security, and social fabric. By empowering smallholder farmers, promoting organic cultivation, and fostering community engagement, the project has catalyzed a broader transformation in the way the hazelnut industry operates in Ordu. The findings offer valuable insights for policymakers, agricultural development practitioners, and other stakeholders seeking to replicate or scale up similar initiatives to revitalize traditional crop systems and enhance rural livelihoods. The paper concludes with recommendations for sustaining the project's momentum and maximizing its long-term benefits for the Ordu region and beyond.

Evaluation of Land Suitability For Durian (Durio Zibethinus) Plants In Parmaksian District, Toba Regency

Simon Haholongan Sidabuke — 2024-12-24

Durian (Durio zibethinus) is known as a plant that has a fairly high economic value which is widely planted on community land in Parmaksian District, Lauhanbatu Regency, North Sumatra Province. This study aims to evaluate the land suitability class for durian as an agroforestry plant in Parmaksian, Toba Regency. Research activities include several stages of activities, namely: preparation, survey, soil analysis in the laboratory, data processing, and mapping. The survey method was carried out to collect soil samples in the field. Durian land suitability class was analyzed using the matching method. The method refers to the references and criteria adopted from the Soil Suitability of Agricultural Crops by the Center for Soil and Agroclimate Research, Bogor, Indonesia. The results showed that the actual land suitability class for durian plants in Parmaksian sub-district, was marginally suitable (S3) on Land Units 1 and 6 and not suitable (N) on Land Units 2, 3, 4, and 5 with limiting factors. are temperature and soil texture. The results of the GIS analysis show that 52.5% of the total sub-district area is marginally suitable (S3) and 47.8% of the total sub-district area is not suitable (N).
