Penilaian Tanah Sekitar Sarana Transportasi dengan Metode Geographically Weighted Regression (GWR)
Get PDFTanah merupakan benda yang bersifat abstrak karena memiliki hak digunakan dan diperdagangkan. Karena sifatnya yang dapat diperdagangkan, diperlukan penilaian tanah untuk mengetahui kualitas dan harga tanah. Pada penelitian ini dilakukan pemodelan nilai tanah untuk mengetahui nilai tanah di sekitar sarana transportasi. Penilaian tanah menggunakan metode Geographically Weighted Regression (GWR) artinya setiap nilai tanah memiliki model matematis. GWR dilakukan dengan kernel fixed gaussian dengan bandwidth optimum Cross Validation (CV). Variabel independen yang dijadikan parameter penilaian untuk nilai tanah ini adalah lebar jalan. radius bandara. radius rel kereta api. jarak ke stasiun. jarak ke terminal. jarak ke pasar. jarak ke pemadam kebakaran. jarak ke rumah sakit. status hukum lahan. guna lahan. dan kesesuaian lahan. Variabel dependen yang digunakan adalah Nilai Indikasi Rata-rata (NIR) dan Zona Nilai Tanah (ZNT) Badan Pertanahan Nasional (BPN). Analisis model dilakukan dengan melihat residu antara variabel dependen dan survei lapangan. Hasilnya apabila dibandingkan dengan nilai hasil pemodelan variabel NIR terdapat perbedaan sebesar Rp 423.831,159,- apabila dibandingkan dengan NIR dan Rp 1.976.916,526,- apabila dibandingkan dengan survei lapangan. Hasilnya apabila dibandingkan dengan nilai hasil pemodelan variabel ZNT terdapat perbedaan sebesar Rp 372.063,117,- apabila dibandingkan dengan ZNT dan Rp 2.041.621,107,- apabila dibandingkan dengan survei lapangan.Kata kunci—GWR, penilaian tanah, sarana transportas
MENINGKATKAN PERAN ENERGI BERSIH LEWAT PEMANFAATAN SINAR MATAHARI
Get PDFDalam 10 tahun terakhir antara tahun 2004 sampai 2013 pemanfaatan energy surya sebagai tenaga listrik meningkat pesat dari 3,7 GW menjadi 139 GW. Hal tersebut disebabkan adanya tuntutan dari Protocol Kyoto yang mewajibkan negara-negara maju untuk mengurangi emisi karbon. Sehingga energi surya yang bersifat renewable dan ramah lingkungan menjadi pilihan disamping energy angin. Di Indonesia kapasitas terpasang Pembangkit Listrik Tenaga Surya (PLTS) belum bersifat komersil. Salah satu PLTS yang dikembangkan sebagai pilot proyek untuk pengembangan PLTS di Indonesia adalah PLTS Cirata berkapasitas 1 MW. Untuk mengestimasi potensi tenaga surya yang berlimpahnya sebagai sumber energi, dilakukan penelitian menggunakan metodologi kualitatif dengan pendekatan studi literatur, analisis database PLTS, diskusi terfokus dan analisis deskriptif. Diharapkan dengan pengalaman dari PLTS Cirata dapat menjadi dukungan untuk pembangunan PLTS lain secara komersil. Untuk itu diperlukan dukungan pemerintah berupa pengukuran potensi tenaga surya di berbagai tempat, pengembangan industri fotovoltaic, serta feed-in tariff yang menarik bagi pengembang PLTS

Get PDFThis study aims to identify entrepreneurial characteristics possessed by young farmers. Young farmers who are the object of study are horticulture farmers in Kabupaten Bandung Barat. This study tries to explain the characteristics of farmers in terms of entrepreneurship. This study focuses on young farmers in Cisarua, Parongpong, and Lembang Subdistricts, with land ownership of no more than two hectares (small scale). The determination of the sample is done by a stratified random sampling method. The strata in this study are young farmers under the age of 40 and farming in the sub-sector of horticulture products in Kabupaten Bandung Barat. The next step is to determine the sample in the study as many as 120 farmers. Farmers who play a role as entrepreneurs are not only experts in the production process, but they have visionary results-oriented business managerial skills. The results of the study show that the majority of respondents have moderate (moderate) entrepreneurial characteristics. This is more due to the farming climate in rural areas which is still moderate, not oriented to professionalism and entrepreneurship. However, young farmers have a desire to develop, so that their business processes are different from those of farmers in general, where young farmers are starting to implement professional work methods in their gardens. The entrepreneurial approach has been seen in the way they do business, where they always want to be better, always look for the latest information, create innovations in the garden, apply management in their farming and take risks
