Abstract

Biomass waste from wood carpentry, which amounts to 15-20% of the woody biomass used, is still not fully utilized. Meanwhile, the biomass can be utilized as a renewable energy source derived from natural materials. The design of energy utilization from biomass waste as an alternative energy source for cooking is a simple utilization effort that can be done by the community. So on the stove design to utilize this waste wood chip biomass is done semi-closed combustion with a limited amount of air entry, so that the heat calorie fire stove that occurs will come out centrally on the hole above the stove. So the selected research topic is the way of utilization of wood chip waste biomass into alternative energy sources for cooking needs. The purpose of this research is to get the design of the utilization of biomass waste (wood chips) as an alternative energy source for cooking. The treatment in this study is the number of holes on the bottom plate of the stove, namely: A has 3 holes, B has 4 holes, C has 5 holes, and D has 6 holes. Based on the result of the analysis of variance (ANOVA), it is seen that the value of F- count is much bigger than the F-Table value either 5% or 1%, so Ho will be rejected and receive H1. This means that the treatment of the number of holes on the plate under the design of the biomass waste stove (wood chips) as a fuel gives a very real effect of its ability in the heat achievement to boil test water as much as 1 liter in the test pan. The treatment which gives effect and different from all other treatments is the D treatment with 6 holes on the bottom plate of the stove, which has a larger LSD value for 1%, but for the C treatment with 5 holes on the bottom plate of the stove is only different at the 5% level. While for treatment C to treatment A and B only differ on level of 5% only. The conclusion of this study is that the best stove design is D treatment, with a faster flame stabilized with a more perfect combustion process and leaving only a small amount of charcoal.

Abstract

Implementasi energi Angin digunakan untuk mengatasi kekurangan suplai listrik PLN, menghemat biaya listrik dan menurunkan emisi gas karbon terhadap lingkungan dalam langkah mendukung konsep bandara dengan green energy atau Eco-Airport, dalam metode perhitungannya menggunakan analisa komponen, pengaruh suhu dan juga dari segi ekonomi pada investasi awal proyek. Kebutuhan energi listrik di bandara Kulon Progo setiap gedung mempunyai konsumsi energi yang berbeda-beda dimana jumlah keseluruhan energi adalah 96.240.205,42 Kwh. Energi alternatif yang bisa digunakan bandara untuk memenuhi kebutuhan energy listrik adalah energy Angin dan bandara membutuhkan 1.129 buah. Berdasarkan metode trend kuadrat terkecil, penggunaan energi listrik pada tahun 2035 di bandara Kulon Progo sebanyak 156.706.5877 Kwh.
