Abstract

To maintain sugarcane freshness, it is crucial to process it promptly after harvest. This study aims to analyze the quality of molded brown sugar derived from raw materials with varying levels of freshness. The research adopts a non-factorial design involving three main treatments: the duration of stay on the first, second, and third days, with three replications. Parameters observed during the molded brown sugar production process include brix, pol, purity, and reducing sugar from raw juice; brix, pol, purity, and reducing sugar from clear juice; color, brix, moisture content, and reducing sugar of sugar. Data analysis is performed using analysis of variance (ANOVA) with the application of Duncan's multiple range test. The purity value in raw juice data H1 with a value of 89.54 significantly differs from data H3 with a value of 73.83. Similarly, reducing sugar in raw juice H1 at 0.74 significantly differs from H3 at 0.93. The purity value in clear juice H1 at 88.34 significantly differs from H3 at 75.40. As for reducing sugar in clear juice, H1 at 0.81 is significantly smaller than H3 at 1.18. Regarding the difference between open-pan and close-pan cooking treatments, it is concluded that the cooking system producing the best molded brown sugar is the close-pan system, evident in both color results and the reduced sugar content of molded brown sugar. The best color for molded brown sugar is found in treatment H1 (day 1) with the close-pan system at 551.40. The lowest reducing sugar content is observed in treatment H1 (day 1) with the close-pan system at 0.94.

Abstract

Penelitian ini dilaksanakan di Politeknik LPP Yogyakarta pada bulan Mei-Agustus 2023. Penelitian ini bertujuan untuk mengetahui dan mempelajari trend produksi tanaman karet di provinsi Jawa Barat. Penelitian ini menggunakan metode kuantitatif, dengan pengambilan data sekunder produksi karet tahun 2013- 2022 dari BPS, dan pengambilan data curah hujan tahun 2013-2022 dari BMKG. Berdasarkan data yang dihimpun dari badan badan terkait, akan menjadi variabel utama pada penelitian untuk menentukan trend analisis produksi 2023-2025 dan melakukan uji korelasi data produksi, curah hujan dan luas lahan untuk melihat nilai signifikansi dan melakukan uji analisis data regresi untuk memperoleh pengaruh nyata antara keterkaitan produksi, curah hujan dan luas lahan. Hasil analisis tren selama 10 tahun pada 2013-2022 mengalami flutuktuasi penurunan yang sangat signifikan dengan rata-rata penurunan yaitu 45.123 ton/tahun dengan rata-rata luas lahan 56.515 Ha. Tren produksi karet juga mengalami penurunan setiap tahunnya dengan persamaan tren yaitu Yt = 56686 + 1242 x t – 480 x t ^ 2 yang dapat diartikan setiap tahunnnya produksi karet di Jawa Barat menurun sebesar 12.300 ton. Penurunan produksi karet disebabkan adanya pengurangan luas areal tanam, yang berdampak pada penurunan produksi.

Abstract

One of the pillars that will support the sugar self-sufficiency program proclaimed by the Indonesian government is smallholder sugarcane farmers. The problems faced are not only on-farm problems such as land management and inaccurate pest control, but also sugarcane farmer cooperatives which have many obstacles. This causes productivity both in terms of cultivation to be less than optimal and the existing cooperatives to be unable to run as originally intended. The purpose of this community service is to provide assistance to people's sugarcane farmers by providing counseling on good sugarcane management, proper sugarcane control, and cooperative management. This activity was carried out with partners from smallholder sugarcane farmers in Sleman who are members of the Koperasi Petani Tebu Rakyat Sido Makmur Abadi which is located at Jl. Raya Selomartani Dayakan, Purwomartani, Sleman. In Yogyakarta. The activity phase that has been carried out is preceded by coordination to discuss the main problems of sugar cane farmers, then there is socialization regarding alternative solutions to farmer problems, and finally assistance in the form of counseling. The results of the activities showed an increase in knowledge regarding good sugarcane cultivation techniques and proper beetle larvae control by 41% and regarding cooperative management by 60%. It is hoped that this increased understanding will become the basis for improving cultivation activities in the 2023-2024 sugarcane planting year so that productivity increases and sugarcane farmer cooperatives are better managed
