Abstract

Increased productivity of cocoa needs high quality of cocoa seeds which are generally provided by certified seed gardens located far from smallholders farm, where seed delivery takes long time and may reduce physiological quality of seeds. One effort to maintain the seed quality is by treatment the seeds with polyethylene glycol6000 (PEG 6000). This study was aimed to study the interaction of PEG 6000 concentration and storage period on cocoa seed quality, and to determine the best concentration of PEG 6000 and storage period to maintain cocoa seed quality. The research was conducted in seed storage room, seed laboratory and green houseof PPPPTK, Cianjur. The experimental design used was a factorial completely randomized design and each combination treatment repeated three times. The first factor was concentration of PEG 6000 of 0%, 20%, 40%, and 60%, and the second factor was the storage period of 3 weeks, 6 weeks, 9 weeks, and 12 weeks. The results showed that concentration of PEG 60% with three weeks storage period was able to minimize the number of moldy seeds. The concentration of PEG 20%, 40%, and 60% were able to prevent seed germination in storage until six weeks. Concentration of PEG 6000 20% was able to maintain moisture content, seed germination, and germination rate.Key words:cocoa seed, storage, recalcitrant, PEG

Abstract

Bima Farmer Group of Dieng Kulon Village, Banjarnegara is a micro-enterprise in the agricultural sector and a center for exotic ornamental plants, particularly Hydrangea flowers. Hydrangea is a leading commodity within the Bima Farmer Group and supports the development of tourism in Dieng Kulon, Banjarnegara. Some of the challenges faced by the group in maintaining productivity include the topography of Banjarnegara, which has a land slope of 45.04%, posing risks to effective and efficient irrigation and fertilization technologies. This research-based community service activity aims to transfer drip irrigation technology to assist in the management of water and nutrients for Hydrangea flower production. The methods used in this technology transfer activity are as follows: 1) Providing assistance and hands-on practice in nutrient management for Hortensia flower production, 2)Establishing demonstration plots using drip irrigation technology for Hortensia flower cultivation, and 3) Conducting activity evaluations to assess the farmers group's level of understanding. Results from this activity show a significant improvement in the farmer’s understanding of the technology transfer, increasing from 3–5% to 85–87%. The average number of Hydrangea flower heads per plant per season before drip irrigation was 6–9, which increased to 11–13 flower heads per plant after implementation. Fertilization became more controlled with the use of drip irrigation, and water usage was reduced by 30–55% compared to conventional methods. Nutrient and water supply remained stable due to the drip irrigation technology. The sustainability of this technology transfer has been well received by the Bima Farmer Group, which plans to expand drip irrigation to other cultivation areas.
