ABSTRACT Palm plants (Arrenga pinnata Merr) until now are not widely cultivated, but they are still forest plants. This plant can be used very much, both as a household appliance and as a home industry. The main results that are widely used in home industries are sap which is processed into palm sugar, which is then used as a sweetener in various kinds of cakes, drinks and others. This research was conducted to determine the factors that influence the production of palm sugar and to find out the risks in the small industry of palm sugar. From this study, it is expected to be used as a material consideration in advancing the palm sugar industry in rural areas, especially in the research area. This research was conducted in the Belimbing Village of Tabanan Regency, Bali. The results of this study indicate that only the factor of craftsman experience and the volume of roomie can affect palm sugar production, from five other factors that are suspected. Making palm sugar from sap material has a large risk of production of 115,587 kg, but it is still easily avoidable by craftsmen. With a risk threshold of producing 35.74 kg of printed palm sugar.

<p>Salah satu potensi sumber energi di Indonesia adalah limbah biomasa berupa limbah padat industri aren. Tujuan penelitian ini adalah untuk mengetahui pengaruh jenis bahan terhadap suhu reaktor dan efisiensi proses gasifikasi limbah padat aren. Bahan baku yang digunakan didapatkan dari Sentra Industri Tepung Aren di Dusun Daleman, Kecamatan Tulung, Kabupaten Klaten. Sebelum diproses bahan dikeringkan terlebih dahulu dengan dijemur di bawah sinar matahari selama sehari, kemudian dilakukan analisa proksimat. Variabel penelitian adalah jenis bahan berupa limbah padat aren murni, campuran limbah padat aren dan tempurung kelapa, serta tempurung kelapa murni. Proses gasifikasi diawali dengan memasukkan bahan ke dalam reaktor tipe <em>Fixed-bed Updraft Gasifier</em>, kemudian dinyalakan sampai keluar gas yang bisa terbakar dan diuji selama satu jam. Syn gas yang terbentuk dianalisa kandungan gasnya, kemudian dibakar untuk mengetahui efisiensinya. Hasil penelitian menunjukkan bahwa jenis bahan mempengaruhi suhu proses di dalam reaktor, dimana suhu optimal dicapai pada gasifikasi tempurung kelapa murni, yaitu proses pengeringan pada suhu 120 °C, pirolisis 340 °C, Reduksi 650 °C, dan oksidasi 721 °C. Gas yang dihasilkan tersebut dapat terbakar selama 15 menit, dibandingkan campuran limbah padat aren - tempurung yang terbakar 8 menit dan limbah padat aren murni yang hanya mampu terbakar 1 menit.</p><p><em>One of the potential energy sources in Indonesia is biomass waste in the form of palm sugar solid waste. The purpose of this study was to determine the effect of the type of material on the reactor temperature and the efficiency of the sugar palm solid waste gasification process. The raw materials used were obtained from the Palm Sugar Flour Industrial Center in Daleman Hamlet, Tulung District, Klaten Regency. Before processing the material is first dried by drying it in the sun for a day, then proximate analysis is done. The research variable is the type of material in the form of pure sugar palm solid waste, a mixture of palm sugar solid waste and coconut shell, and pure coconut shell. The gasification process is initiated by inserting the material into the Fixed-bed Updraft Gasifier type reactor, then igniting the flammable gas and testing it for one hour. The syn gas formed is analyzed for its gas content, then burned to find out its efficiency. The results showed that the type of material influences the process temperature inside the reactor, where the optimum temperature is achieved in pure coconut gas gasification, namely the drying process at 120 °C, pyrolysis 340 °C, Reduction 650 °C, and oxidation 721 °C. The resulting gas can burn for 15 minutes, compared to a mixture of aren solid waste - shells that burn for 8 minutes and pure aren solid waste that can only burn for 1 minute.</em></p>

The disposal of biomass waste is of great economic and environmental importance because it can be considered as a sustainable and renewable source of energy. Biomass waste can be converted into H2-rich fuel gas quickly by low temperature catalytic gasification technology. In the paper, fowl manure, a typical biomass waste, was pretreated by washing and the properties of the manure sample before and after pretreatment was investigated. The properties of the manure samples prepared depend strongly on washing method. Nearly all the minerals were removed from the waste by the treatment in the sequence of dilute HCl acid and HF acid washing. The difference in the pyrolysis behaviors of the samples before and after acid washing was ascribed to the changes in the organic components and the minerals present in HC during the pretreatment. A distinct catalytic effect of the minerals contained in CM on its pyrolysis behavior was observed.
