Abstract

Sigupai is one of the local rice varieties that characterizes the Southwest Aceh district. This variety has many outstanding characteristics that make this variety a commodity that is in great demand and expensive. The existence of this variety is now challenging to find. The harvest age is long enough so that people rarely cultivate sigupai variety. As a result, many traders or farmers often practice adulteration, which will ultimately incur losses for consumers. The purpose of this study was to analyze the authenticity of sigupai rice based on non-destructive qualitative and quantitative analysis using a portable near-infrared spectrometer. Qualitative analysis used 86 samples consisting of 43 sigupai rice and 43 inpari rice, while quantitative analysis used 44 rice samples mixed between sigupai rice and inpari rice with a percentage of 0% - 30%. The two approaches were applied by partial least square-discriminant analysis (PLS-DA) and partial least square regression (PLS-R) for qualitative and quantitative analysis. Qualitative analysis using the partial least square-discriminant analysis (PLS-DA) method obtained the best results for validation data using original data with accuracy, sensitivity, specificity, and false alarm rate, respectively 89.29%, 92.86%, 85.71%, and 14.29%. At the same time, the quantitative analysis used the partial least squares regression (PLS-R) method. The best results were obtained using derivative SG1 pre-treatment with r = 0.96, SEC = 1.52%, SEP = 1.50%, RPD = 5.93, and consistency = 100.69%. From this study, the portable near-infrared spectrometer has the potential to be used as a tool for analyzing the authenticity of sigupai rice in the field.

Abstract

Pisang Mas Kirana merupakan salah satu varietas pisang yang populer dipasar domestik dan ekspor. Umur simpan yang pendek menjadi kendala utama dalam ekspor buah varietas ini. Salah satu cara untuk mempertahankan mutu buah pisang adalah menunda kematangan (mempertahankan masa green life) dengan eating quality yang tetap disukai konsumen. Proses kematangan pisang dapat diperlambat dengan menggunakan etilen absorber bag (EAB) berbahan Zeolit-KMnO4 dan silica gel. Tujuan penelitian adalah mengkaji pengaruh penggunaan EAB untuk menunda kematangan buah terhadap perubahan mutu dan eating quality saat pisang matang. EAB diaplikasi pada pisang yang dikemas menggunakan plastik HDPE yang diberi perforasi berdiameter ± 2 mm sebanyak 18 lubang. Berat pisang perkemasan 1.000 ± 50 g. Skenario penundaan kematangan adalah 12 dan 20 hari yang disimpan pada suhu ruang (27 oC± 2°C). EAB dilepas sesuai skenario kemudian dilakukan penyimpanan pada suhu ruang untuk proses pematangan alami dan pemajangan. Hasil penelitian menunjukkan bahwa aplikasi EAB dapat menunda kematang pisang sesuai skenario yaitu 12 dan 20 hari. Saat pisang dibuka dari kemasan masih berwarna hijau dengan indek kematangan 1. Setelah disimpan di suhu ruang, pisang matang alami setelah 2 hari yang ditunjukkan dengan indeks kematangan 5. Setelah matang, pisang dapat bertahan sampai dengan 3 hari berdasarkan uji organoleptik terhadap rasa dan warna kulit dengan nilai 3 dari skala nilai 1-5. Eating quality yang dinyatakan dengan oBrik. menunjukkan pisang yang ditunda dengan EAB menghasilkan nilai 29,6 oBrix – 31,0 oBrix, sedang kontrol 28,1 oBrix. Waktu simpan sampai dengan display mencapai 18 dan 25 hari, sementara kontrol hanya sampai 12 hari.

Abstract

The process of lifting fresh fruit bunches (FFB) of oil palm to trucks is generally still done manually, with a heavy workload and potential for injury. The existing lifting equipments are powered by an internal combustion engine at a high cost. The purpose of this study was to design and test an equipment for lifting FFB of oil palm into the bed of a truck by utilizing the weight of the truck. The weight on the rear wheels of the truck when backing is used to press a pair of hydraulic cylinders whose pressure is transferred to a hydraulic cylinder driving a scissor type lifting mechanism. FFB which are loaded in a low trough, can be loaded onto the truck easily and quickly. This lifter was designed to lift 400 kg of FFB with a lifting height of 2.4 m. In the top position, the FFB bed is inclined 20o so that it slides into the tailgate. The test results show that this lifter could perform well with a work capacity of 17.22 tons/hour, 2.3 times greater than the manual capacity, and with low work risk. The basic operational cost is IDR 4,894/ton FFB while manually it is IDR 9,008/ton FFB.

Abstract

Applying the concept of utilizing rice mill waste as an energy source can support the increase in the productivity of renewable energy. The exergonomic concept can be used as one of the steps to see opportunities for husks to be used as an energy booster in a rice mill system that has been integrated with a gasifier. Specific Exergy Cost (SPECO) is used as the method, that combines exergy and economic analysis by applying the cost concept to the thermal system. Based on the analysis results, gas producers can replace diesel fuel in small-sized rice mill systems. Compared with these inputs, husks and energy products from the gasifier can produce nearly 6 and 4 times the exergy, respectively. In addition, gas utilization producers can also reduce fuel expenditure costs by up to 84.67%.
