Abstract

AbstrakTujuan penelitian ini adalah mendiskripsikan kurva moisture ratio dan melakukan pendugaan lama pengeringan dendeng ikan manyung (Arius thalasisinus) dengan Pengering Energi Surya YSD-UNIB12. Percobaan dilakukan dengan mempersiapkan sampel sesuai dengan cara pembuatan dendeng ikan dan selanjutnya tiga perlakuan ditetapkan yaitu ketebalan dendeng (0,5 cm dan 1 cm), lama perendaman dalam larutan bumbu (1 jam, 3 jam dan 5 jam), dan posisi sampel pada rak yaitu rak1 (bawah), rak2 (tengah) dan rak3 (atas), masing-masing dilakukan dengan tiga ulangan. Pengamatan dilakukan terhadap suhu dan kelembaban relatif ruang pengering dan udara luar, dan penurunan berat sampel sepanjang proses pengeringan dari pukul 09.00-16.00 WIB sampai pengeringan selesai dengan kadar air akhir ikan 12%. Hasil percobaan menunjukkan bahwa pengering mampu menaikkan suhu udara 15,2 oC lebih tinggi dari udara luar dan menurunkan kelembaban relatif 31% lebih rendah dari udara luar. Model kurva hubungan antara moisture ratio dan kadar air dengan waktu pengeringan adalah kuadratik. Lama pengeringan hanya dipengaruhi oleh tebal dendeng dan posisi di rak. Rata-rata waktu penyelesaian pengeringan berkisar antara 11,9 jam sampai 30,3 jam.Kata kunci: kadar air, lama waktu pengeringan, moisture ratio, pendugaan Abstract The objectives of this study were to describe the curves of moisture ratio and moisture content and to predict drying times of the jerked flesh of Manyung fish (Arius thalassinus) dried by utilizing YSD-UNIB12 solar. The experiments were set up by employing three treatments, i.e., thickness of jerked flesh (0.5 cm and 1 cm), flesh submerging time in spices solution (1, 3 and 5 hours), and rack’s positions that were rack1 (lower), rack2 (middle) and rack3 (upper) with three replications each. The observation was carried out at 9 AM to 4 AM for drying room temperature and relative humidity, ambient temperature and relative humidity, and weight of samples along drying process until the fish moisture content of 12%. The result of experiments showed that the dryer generated the drying chamber temperature 15.2oC higher than the ambient temperature, and the drying chamber relative humidity 31% lower than the ambient relative humidity. Both models of curves of moisture ratio and moisture content versus drying time were quadratic (polynomial second order). Only the position of the rack and the thickness of jerked fish affected drying time. The drying time to produce dry jerked fish varied from 11.9 hours to 30.3 hoursKeywords: drying time, moisture content, moisture ratio, prediction

Abstract

Dalam menganalisis kemampuan lahan selalu menggunakan data keruangan. Data tersebut merupakan data faktor yang akan menentukan satuan kemampuan lahan diantaranya jenis morfologi, kestabilan lereng, kedalaman efektif dan ketersediaan air. Data lingkungan tersebut ditumpang-susunkan dan diberi nilai untuk mendapatkan kelas kemampuan lahan sesuai potensinya. Tujuan penelitian ini menentukan kemampuan lahan, membandingkan penggunaan lahan dan merekomendasikan pengembangan sesuai kemampuan lahan di wilayah Kabupaten Musi Rawas Provinsi Sumatera Selatan. Pengolahan data pada satuan kemampuan lahan dilakukan dengan pemodelan spasial menggunakan sistem informasi geospasial yaitu dengan metode tumpang susun (overlay). Hasil analisis kelas kemampuan lahan terdiri dari 3 kelas kemampuan lahan yaitu kelas kemampuan lahan b dengan klasifikasi pengembangan rendah dan diarahkan untuk tetap dilestarikan dan tidak merusak tutupan lahannya. Kelas kemampuan lahan c dengan klasifikasi pengembangan sedang, arahan pengembangan harus mendapat persetujuaan telaah tata ruang. Pada kelas kemampuan lahan d dengan klasifikasi pengembangan agak tinggi yang mempunyai sedikit penghambat perlu perhatian terutama pada lahan sawah, sungai, danau dan rawa agar tidak dialih fungsikan, sedangkan kawasan rawan banjir tidak ada pembangunan. Pada rentang waktu antara tahun 2008 ke tahun 2017, ternyata ada perubahan luasan kemampuan lahan. Pada tahun 2008 luasan kemampuan pengembangan agak tinggi seluas 53,17%, dan pada tahun 2017 menjadi seluas 53,39%. Untuk kemampuan pengembangan sedang, pada tahun 2008 seluas 44,92%, menjadi seluas45,72% pada tahun 2017. Dengan kurun waktu yang sama pada tahun 2008 kemampuan lahan rendah seluas 1,91% dan pada tahun 2017 menjadi seluas 0,89%.

Abstract

Tebat Pulau Village is a formerly protected forest area that has become a community social forest processed and planted with robusta coffee. Robusta coffee from the Tebat Pulau Village Farmers Group is of good quality because it is in great demand and attracts the attention of large buyers. However, the quality profile, the roasted coffee criteria, and the preferred quality of the brewed coffee are not yet known. Therefore, this research was conducted to determine the quality profile of rice coffee, the physical and chemical characteristics of ground coffee and the brewing quality of robusta coffee during roasting time. The experimental design used was Completely Randomized Design with one factor. The factor tested was roasting time (P), which consisted of 4 treatment levels, namely P1:10 minutes, P 2:11 minutes, P3:12 minutes, P4:13 minutes with roaster temperature 200°C and bean temperature 107°C. The research was carried out with three repetitions to produce 12 experimental units. The results showed that the coffee from the Tebat Pulau Village Farmer Group had quite large coffee beans with a water content value of 9.00%, had quite a lot of lanang (peaberry bean) coffee beans, and had a total defect value of 13.83. Ground coffee samples with a long roasting time significantly affected water content, color, ash content, coffee essence, and caffeine content. The best-brewed coffee quality was obtained at 12 minutes of roasting time with a final score of 8.50, included in the "fine" category.
