Abstract

Paddy drying was performed using a hybrid drier utilizing solar energy, biomass and combined solar-biomass energy as energy sources. This research objective was to evaluate performance of the hybrid paddy drier using solar energy and paddy straw and coconut coir biomass. The experimental and descriptive method was used. The result showed that the drier with solar system was capable to generate temperature of drying chamber to 40.42 °C in average, while the average relative humidity was 41.45%. The paddys final moisture was 14.88%w.b after 7 hours of drying with drying rate of 0.64% d.b/h and energy consumption of 32,595.32 kJ. Paddy drying with biomass energy system was capable to obtain drying chambers temperature of 33.8 °C in average, the average relative humidity of 57%, the final moisture of 15.57%, the drying rate of 0.50 %d.b/h and energy consumption of 160,662.15 kJ with the same drying times. The solar-biomass drying system was capable to achieve temperature of 39.98 °C, the average relative humidity of 45.85 %, the final moisture of 15.33%w.b with drying rate of 0.55 %d.b/h and energy consumption of 136,457.76 kJ. Therefore, the best performance for drying paddys was with the solar drying system. ABSTRAKPengeringan gabah dapat dilakukan menggunakan alat pengering energi surya, energi biomassa dan energi kombinasi surya dan biomassa.  Penelitian ini bertujuan untuk menguji kinerja alat pengering gabah hybrid energi surya dan biomassa jerami padi dan sabut kelapa.  Metode yang digunakan dalam penelitian ini adalah metode eksperimental dan deskritif.

Abstract

This study was aimed to apply Peleg Model to analyze rehydration of dried tekwan at several variations of water immersion temperature.  The method used was descriptive and experimental of one factor treatment (Non Factorial), which was immersion temperature with four treatments level (30, 45, 70 and 90oC), each treatment was done triplicate.  The parameter observed was moisture content at times of observation.  The result showed that the Peleg Model coefficients (K1 and K2) were inversely affected by the temperature.  The relationship was expressed into non-linear regression (polynomial) with R2 value of 0,973 and 0,988.  It showed that the obtained Peleg model could be applied adequately for the rehydration of dried tekwan at some immersion temperature. The resulting model also met the statistical criteria with the largest SEE and MRE values 6.73% and 3.58%. The model could predict the dried tekwan rehydration best at the temperature of 30oC and 45oC with the smallest SEE and MRE values.

Abstract

Tujuan dari kegiatan pengabdian ini adalah untuk meningkatkan pengetahuan dan keterampilan para pengurus Bank Sampah Palembang Lestari dalam membuat alat/composter sederhana yang dapat digunakan dalam operasionalmya sehari-hari. Kegiatan dilaksanakan di rumah Direktur Bank Sampah Palembang Lestari yang terletak di Kecamatan Jakabaring, Palembang. Kegiatan ini berbentuk penyuluhan, pelatihan serta pendampingan dalam pembuatan alat composter sederhana. Composter yang dibuat adalah tipe drum berputar dengan posisi horizontal. Pelatihan dilakukan dengan praktek langsung oleh tim pengabdian dan para peserta. Kegiatan pengabdian masyarakat ini mendapatkan respon yang baik. Target kegiatan untuk menghasilkan minimal satu buah alat composter sederhana telah tercapai. Bahkan, pengurus Bank Sampah Palembang Lestari telah mampu membuat secara mandiri dan mengembangkan model lain dari alat composter. Keberhasilan pembuatan alat composter sederhana ini diharapkan dapat menunjang keberlangsungan kegiatan operasional Bank Sampah Palembang Lestari terutama dalam pengelolaan sampah organik di lingkungan Jakabaring Palembang.

Abstract

The objectives of this research were to study the effects of freezing period of gluten and levels of gabus fillet fish addition on the characteristics of gluten pempek. This research was conducted at the Laboratory of Agricultural Product Chemistry, Department of Agricultural Technology, University of Sriwijaya, from July to October 2005. This research used completely randomized factorial design with two treatments and three replications. The treatments were freezing period (0, 6, and 12 hours) and levels of gabus fillet fish addition (0, 5, 10, and 15%). The observed parameters were content of water, ash, protein, carbohydrate and fat. The results showed that freezing time affected significantly on water content but not to the other parameters. Fillet fish addition level had significant effect on ash and fat, but had no significant effect on other parameters. The best treatment was gluten pempek using freezing time of 12 hours and 15% of fish addition level.

Abstract

Agricultural insurance is one solution for farmers to minimize the risk of crop failure. The condition of climate change, especially flooding that occurs in paddy fields, of course requires an effort to minimize the risk of crop failure for farmers, one of the efforts that have been made is to provide agricultural insurance for farmers. In Ogan Komering Ilir (OKI) Regency this agricultural insurance program has been implemented. Therefore research or study is needed on farmers 'perceptions of agricultural insurance as an effort to minimize the risk of crop failure, so the purpose of this study is to measure farmers' perceptions of agricultural insurance as an effort to minimize the risk of crop failure in rice fields.  Identify what factors support and hinder the implementation of insurance and formulate recommendations for developing agricultural insurance that can be done.  Hasil dari penelitian ini menujukkan bahwa Persepsi Petani terhadap asuransi Pertanian secara umum sangat baik. Indikator yang masih perlu diperbaiki adalah sosialisasi asuransi pertanian yang baru dilakukan satu kali serta perbaikan pada jumlah klaim asuransi yang diajukan petani baik dari lamanya waktu pembayaran maupun dalam jumlah klaim yang dibayarkan. Rekomendasi pengembangan program yang diprioritaskan agar asuransi pertanian dapat berkelanjutan adalah kegiatan sosialisasi secara berkala dari pihak perusahaan penyedian asuransi pertanian, pemilahan tingkat premi dan klaim berdasarkan tipologi lahan, peninjauan langsung oleh pihak asuransi saat ada klaim yang diajukan petani sehingga lebih objektif.
