Abstract

The necessity of energy become a priority by goverment at this time, because the final consumtion of national energy on 2000-2012 increases 2,9% for each year. By using the fossil energy continuesly that can make the availibility of energy become rare, there are so many policy that created by goverment to control this problem, one of this using the policy is alternative energy. The alternative energy can get from some resources and products such as water energy, wind, geothermal, biodiesel, and biomass. Briquettes is a pottential fuel and very relieble as alternative energy for household needs and able to supply and a long time. Pre-design planning of rubber seed shell briquettes is using slow pyrolysis system. Where, the shell heated in 350º C - 400º C in 1 atm pressure for 6 hours process. The pre-design planning will build in Landak district of West Borneo. Pre-design planning of rubber seed shell briquettes that using slow pyrolysis system will build on 2020 with 8.900 ton/year capacity. The process is raw material preparation, pyrolysis reaction, separation and purificatin, and product handling. Based on economic analysis this plant feasible to set based on the economic aspects as follows : ROIAT(%) : 75,7%, POT(tahun) : 1,2 , BEP (%) : 37%, IRR(%) : 19,47. Key word : energy, briquettes, slow pyrolysis

Abstract

Bekisting merupakan struktur-struktur sementara yang berfungsi sebagai alat penghubung antara desain dan pelaksanaan konstruksi, Struktur-struktur permanen tidak bisa dibangun tanpa struktur - struktur sementara tersebut. Komponen bekisting pada pelaksanaan juga membutuhkan biaya yang besar, oleh karena itu perencanaannya harus dipertimbangkan faktor ekonomisnya. Pemilihan jenis bahan bekisting sering menjadi masalah bagi pelaksanaan pekerjaan, yaitu bagaimana memilih bahan yang tepat dan ekonomis misalnya bahan dapat digunakan secara berulang – ulang, pembongkarannya mudah dan cepat, dapat menahan beban selama pengecoran, harga relatif murah dan hasilnya sesuai dengan yang diharapkan. Tujuan dari penelitian ini adalah : 1. mengetahui seberapa besar nilai penyusutan setelah pemakaian bekisting pada setiap lantai dan balok di bangunan Gedung Alexanria secara berulang. 2. Mengetahui efektifitas penggunaan bekisting secara berulang pada pekerjaan lantai dan balok, pada gedung lantai I sampai lantai IV 3. Mengetahui Berapa waktu pelaksanaan yang efektif dan biaya yang di butuhkan untuk perkerjaan bekisting pada tiap lantai dan balok Gedung Alexanria. Jenis penelitian (metode penelitian) yang di gunakan adalah metode penelitian deskriptif Hasil penelitian terhadap pekerjaan bekisting konvensional Gedung Alexandria menunjukkan bahwa dari segi biaya Rp. 169.213.806 perlantai dan waktu yang efektif untuk pekerjaan bekisting adalah dua (2) minggu. Kata Kunci : Bekisting Multiplex, Efesiensi Biaya, Efektifitas Waktu
