Abstract

Kelompok Tani Minyak Serai Wangi Berkat Yakin merupakan kelompok tani penggerak diDesa Balai Batu Sandaran yang mengelola industri penyulingan minyak serai wangi. Pengolahan serai wangi harus memperhatikan aspek efisiensi dan efektifitas agar mampu memberikan keuntungan yang maksimal dan meningkatkan nilai tambah pada serai wangi. Tujuan penelitian adalah menentukan nilai tambah dan kelayakan finansial usaha minyak serai wangi pada Industri Minyak Serai Wangi Berkat Yakin Desa Balai Batu Sandaran. Analisis data dilakukan dengan Metode Hayami dan parameter kuantitatif dalam analisis kelayakan finansial ditunjukkan oleh indikator seperti: Benefit Cost Ratio (B/C),Internal Rate of Return (IRR), Net Present Value (NPV) dan Payback Periods (PBP). Hasil analisis nilai tambah yang diperoleh dari hasil pengolahan serai wangi dengan bahan baku 25.000kg menjadi minyak serai wangi sebanyak 400 kg adalah Rp.3.080/kg. Sedangkan rasio nilai tambah produk minyak serai wangi adalah sebesar 84%, artinya 84% dari nilai output (produk minyak serai wangi) merupakan nilai tambah yang diperoleh dari proses pengolahan serai wangi menjadi minyak serai wangi. Hasil perhitungan analisis kelayakan finansial industri minyak serai wangi didapatkan NPV Rp. 1.635.698.925,- IRR 37,60%,B/C Ratio 1,45, dan PBP adalah 3 tahun 6,5 bulan. Ditinjau dari aspek ekonomi, usaha produksi minyak serai wangi dapat dikatakan layak dan menguntungkan.

Abstract

West Sumatra-Indonesia has potential to plant coconut due to the coastal location, sunshine level with average temperature 27oC. Coconut is a very productive plant. Coconut dehusking is one of the process that takes a lot of time and energy. Most of the farmer still using human manual labour with the help of tools made of iron or wooden crowbar that is mounted standing vertically with the blade facing upward about 80 cm from the ground. To increase the number of coconut products, it is designed the coconut dehusker machine. The main component of the machine were two rollers that rotate each other in opposite directions with each roller embedded iron-shaped nails that work to tear the coconut husk. Each roller has a different rotational speed. This machine has dimensions of 98 cm x 51 cm x 95 cm. Roller length is 50 cm and diameter 4 inches. The power source of the machine is a 2 HP electric motor, the speed was reduced by using 2 speeds reducer with the ratio of 1:20 and 1:30 respectively. From the performance test of this machine can dehusk 100 coconuts per hour. The operational basic cost of the machine equal to Rp 129.89 per coconut (about 1 cent) and Break Event Point is 12.387 coconut per year from the result of the performance test. From the economic analysis machine can be concluded that the use of this machine is better when compared to human labour which has limitation to duration and capacity.

Abstract

Difference and variation of leaves shape is usually used as primary identifier of the plant species. But some plants may have a similar leaf shape and thus require another more accurate identifier. This study applied principal component analysis (PCA) methods for identifying tropical plant species from the shape of the leaves. This method simplified the observed variables by reducing the dimensions of the information that is stored as much as 75%, so it did not eliminate important information and can save the data processing time. There were 100 images of leaves taken from several sides of the leaf in JPEG format with which the shape of leaves were look similar, like citrus (Citrus aurantifolia), durian (Durio zibethinus), guava (Psidium guajava), mango (Mangifera indica), jackfruit (Artocarpus heterophyllus), avocado (Persea americana), rambutan (Nephelium lappaceum), sapodilla (Manilkara zapota), red betel (Piper crocatum) and soursop (Annona muricata). Identification of those 10 kind plant leaves produced 97% accuracy rate. Measurement systems were designed using the K-fold Cross Validation with k = 10, the results of experiments shown omission error occurs on the leaves of guava, jackfruit and red betel while twice commission error were found on the leaves sapodilla and once on citrus leaves.
