Judul: Pola Rantai Pasok Ternak Sapi di Kabupaten Kepulauan Selayar (Studi Kasus di Desa Bonea Makmur)
Abstrak: Pola rantai pasok ternak sapi merupakan alur tataniaga yang berkaitan dengan distribusi ternak sapi yang terdiri atas pengaturan produk, informasi maupun keuangan. Tujuan dalam penelitian adalah untuk mengidentifikasi pola rantai pasok ternak sapi dari peternak sampai ke konsumen. Metode yang digunakan dalam penelitian adalah metode wawancara dan survey dengan teknik pengambilan sampel snowball sampling didapatkan jumlah responden 17 orang yang terdiri atas peternak, pedagang, dan konsumen (tukang jagal). Hasil penelitian menunjukkan terdapat dua jenis pola rantai pasok pada tataniaga ternak sapi yakni pola pertama peternak yang menjual langsung ternak sapi ke tukang jagal dan pola kedua peternak menjual sapi ke pedagang ternak untuk selanjutnya dijual kembali ke tukang jagal. Pola pertama merupakan pola yang paling efisien dan memberikan keuntungan yang tinggi bagi peternak. Kata kunci: peternak, rantai pasok, ternak sapi, The cattle supply chain pattern is a commercial flow related to cattle distribution consisting of product regulation, information, and finance. The purpose of the study is to identify the pattern of cattle supply chain from farmers to consumers. The method used in the study was an interview and survey method with snowball sampling techniques. Within this snow ball sampling it was obtained the number of respondents 17 people consisting of breeders, traders, and consumers (butchers). The results showed that there are 2 types of supply chain patterns in the cattle trade, which the first pattern is the farmers selling cattle directly to butchers and the second pattern is the farmers selling cattle to livestock traders to be resold over to butchers. The first pattern is the most efficient and provides highest profit for farmers. Keywords: cattle, farmer, supply chain

Judul: Keragaan farming of bakalancattle (case study:  farmer and  breeder group of tanjung lurah, nagari salimpauang, kabupaten Tanah Datar)
Abstrak: Nagari Salimpauang merupakan salah satu wilayah di Kecamatan Salimpauang, Kabupaten Tanah Datar, Provinsi Sumatera Barat dimana penduduknya banyak mengusahakan penggemukan sapi. Namun untuk mengembangkan usahanya, para peternak memiliki permasalahan seperti lahan, pengolahan limbah, ketersediaan input, dan tenaga kerja. Salah satu solusi untuk mengatasi permasalahan tersebut yaitu melalui pengelolaan dengan Kelompok Tani Ternak Tanjung Lurah. Tujuan dari penelitian ini yaitu (1) Menganalisis biaya dan penerimaan, dan (2) Menganalisis pendapatan dan rasio penerimaan dan biaya. Hasil perhitungan pendapatan atas biaya tunai per ST per tahun dan nilai R/C rasio yang paling besar diperoleh peternak skala besar. Sementara itu perhitungan pendapatan atas biaya total per ST per tahun menghasilkan nilai positif dan nilai R/C rasio lebih dari satu untuk semua skala, sehingga usaha ternak menguntungkan. Usaha pada peternak skala besar yang lebih baik dibandingkan skala kecil karena keuntungan yang diperoleh paling besar dan nilai R/C rasio nya yang paling besar., Nagari Salimpauang is located at Kecamatan Salimpauang, Kabupaten Tanah Datar, West Sumatera Province where the majority of people do fattening cattle husbandry for living. Meanwhile to develop the business, the breeders face through several obstacles such as area availability, waste management, input availability and labor. One of solution to solve those problems is by implementing supervision with farmer and breeder group of Tanjung Lurah. This study was aimed to (1) analyze cost and revenue, and (2) analyze profit and ratio of revenue and cost. Measurement result of profit based on cash cost per livestock unit (satuan ternak, ST) per year and biggest R/C ratio value were gained by wide– scale breeder. Otherwise, calculation of profit based on cash cost per ST per year indicated positive value and R/C ratio values which were more than 1 for every scales, therefore the business is considered profitable. Business by wide–scale breeder was better compared to small–scale one because of the most profit obtained and biggest R/C ratio value.

Judul: Synthesis of Molybdenum Trioxide (MoO3) by Electrochemical Method for Electrochromics Application
Abstrak: Molybdenum trioxide (MoO3) thin films have been deposited on glass substrates by electrochemical method using ammonium heptamolybdate tetrahydrate ((NH4)6Mo7O244H2O). The films were deposited onto glass substrates as the control temperature at 25○C and annealing treatment at 350○C for 30 mins. The MoO3 thin films were investigated by UV-Vis, X-ray diffraction techniques (XRD), Scanning Electron Microscopy (SEM). The JCPDS card show that orthorhombic MoO3 (α- phase) has been formed. Molybdenum trioxide MoO3 formation was also confirmed by JCPDS card no. 35-0609. The SEM photographs revealed that the spherical and rod-like morphology and their grains size increased with increasing of heating temperatures. The measurement results show that the MoO3 thin film prepared at 350°C transmited about 80% of the visible spectrum. The effect of different heat treatments on surface morphology, thickness and optical properties of the films are discussed in this thesis.
