Abstract

The purpose of the study is to analyze the added value of Liberika coffee powder in Samustida Village, Teluk Keramat District. The Mitra Sejahtera Cooperative in Samustida Village has been processing coffee into coffee powder. Using the Hayami method, the research analysis found that the added value of processing coffee powder was Rp 6,930/kg, with an added value ratio of 39.33%. The coffee powder processing business received a positive added value or was classified as a moderate increase in value. To increase income, production of coffee powder must be increased, and efforts must be made to find raw materials, as well as to utilize the resources available within the cooperative according to their respective roles and functions.

Abstract

Hydroponics is one of the vegetable cultivation techniques that is beginning to develop in Sambas. In addition to its stable price range of IDR 5,000 - IDR 6,000 per 200 gram package, consumers prefer it because the vegetables tend to be healthier and cleaner than similar vegetables grown in soil. This study aims to analyze consumer willingness to pay (WTP) for hydroponic vegetables in Sambas District. The research method used is the Contingent Valuation Method (CVM) with data collection through surveys of consumers who have purchased or are interested in hydroponic vegetable products. Data collection was carried out in several locations that are centers for hydroponic vegetable cultivation. The results of the study show that the average WTP that consumers are willing to pay for hydroponic vegetables in Sambas is IDR 6,980 per 200 gram package. Household income and expenditure have very little influence on the purchase of hydroponic vegetables. These findings indicate the market potential for hydroponic vegetable products in Sambas, even though the WTP value of consumers in this region is relatively lower than the results of studies in other regions, which are generally influenced by factors such as health awareness, product quality, and environmental concerns. The results of this study are expected to serve as a reference for business actors and policy makers in the development of the hydroponic vegetable agribusiness in Sambas, particularly in determining pricing and promotion strategies that are in line with the purchasing power and preferences of local consumers.

Abstract

Sambas Liberica coffee holds significant strategic value as a leading local commodity. The main challenge on the ground is low productivity due to suboptimal propagation techniques. Many farmers still rely on generative propagation (from seeds), which results in plants with inconsistent traits and suboptimal growth. Vegetative propagation has the potential to accelerate the regeneration of high-quality, uniform plants. High-quality coffee seedlings can be obtained through vegetative propagation using the shoot-grafting method. There is a need to identify the most effective vegetative propagation technique for Sambas Liberica coffee. This study aims to determine the optimal propagation technique based on germination and growth success rates. In this study, vegetative propagation techniques will be tested, specifically top-grafting, as well as the use of Trichoderma-treated growing media. The research was conducted in the greenhouse of the Agribusiness Department at the Sambas State Polytechnic. The study subjects were Liberica coffee seedlings; the rootstocks were 7-month-old seedlings, and the scions were obtained from Liberica coffee parent trees in Kartiasa Village. The experimental design used in this study was a two-factor completely randomized design (CRD) with three replicates. The results showed that growing media treated with Trichoderma yielded a 36% higher success rate for topgrafting. The oblique grafting method yielded a higher success rate of 39%, compared to the center grafting method, which had a success rate of 14%.
