Abstract

South Kalimantan is one of the natural habitats of gelam wood. In South Kalimantan, gelam wood can grow well and fertile. This makes the availability of gelam wood abundant and can be used for various purposes, one of which can be used as raw material for wood pellets (biomass energy). Wood pellets made from gelam wood have not been widely studied, so it is necessary to know the effect of the size of gelam wood powder and the addition of the percentage of adhesive on the physical properties of gelam wood pellets. Wood pellets made from gelam were made using various sizes of powder (mesh) 40, 50, and 60 as well as using flour adhesive (percentage of adhesive 5%, 10%, and 15%). Gelam wood pellets were then tested for physical properties in order to determine their performance. From the research that has been carried out, it is found that the volatile matter content, ash content, and water content tend to increase with the smaller size of the gelam sawdust. Meanwhile, the calorific value and fixed carbon content have a tendency to decrease with the smaller size of the gelam sawdust. volatile matter content, ash content, and water content tend to increase as the percentage of adhesive is increased. Meanwhile, the calorific value and fixed carbon content tend to decrease with the increase in the percentage of the amount of adhesive.

Abstract

AbstrakPemanfaatan potensi biomassa yang terdapat di Kalimantan Selatan dengan raw material melimpah, salah satunya adalah kayu gelam yang berpotensi digunakan sebagai bahan bakar co-firing boiler untuk pembangkit listrik tenaga uap sehingga dapat mengurangi penggunaan bahan bakar fosil batubara. Serbuk kayu gelam dapat dijadikan sebagai bahan baku pellet dengan penambahan perekat atau tanpa perekat. Dalam penelitian ini menganalisa bagaimana penambahan perekat tepung tapioka menpengaruhi karaktersitik sifat fisik pellet kayu gelam. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh variasi ukuran mesh dan persentase perekat tapioka terhadap sifat fisik pellet kayu gelam. Metode yang digunakan adalah secara eksperimental. Pellet kayu gelam dibuat dengan menggunakan variasi ukuran serbuk (mesh) 40, 50, dan 60 serta menggunakan perekat tapioka dengan persentase perekat 5%, 10%, dan 15%. Pellet kayu gelam selanjutnya di lakukan pengujian di laboratorium Baristand Banjarbaru. Pellet kayu gelam diuji meliputi pengujian sifat fisik yang terdiri dari nilai kalor, kadar air, kadar abu, kadar zat-zat terbang (volatile matter), dan kadar karbon terikat (fixed carbon). Hasil pengujian menunjukkan pellet kayu mengalami peningkatan pada kadar air, kadar abu, dan kadar zat-zat terbang seiring semakin kecilnya ukuran serbuk (mesh) kayu gelam. Sedangkan kadar karbon terikat dan nilai kalor pellet kayu mengalami penurunan seiring dengan semakin kecilnya ukuran serbuk (mesh) kayu gelam. Sehingga dapat disimpulkan bahwa penambahan perekat tapioka mempengaruhi karakteristik sifat fisik pellet kayu, semakin tinggi persentase perekat maka kadar air, kadar zat-zat terbang, dan kadar abu semakin meningkat. Sementara itu, penambahan persentase perekat pada pellet kayu menyebabkan penurunan pada kadar karbon terikat dan nilai kalornya. AbstractUtilization of the potential of biomass found in South Kalimantan with abundant raw materials, one of which is gelam wood which can be used as boiler fuel for steam power plants to reduce the use of coal fossil fuels. Gelam wood is processed into wood pellets using tapioca flour adhesive. The gelam wood pellet then carried out tests in the form of testing physical properties which included water content, ash content, volatile matter content, fixed carbon content, and calorific value. Wood pellets made from gelam were made using various sizes of powder (mesh) 40, 50, and 60 as well as using tapioca adhesive (percentage of adhesive 5%, 10%, and 15%. The gelam wood pellets were then tested for physical properties to determine their performance. The test results showed that wood pellets increased in moisture content, ash content, and volatile matter content along with the smaller size of gelam wood powder (mesh). While the carbon content and calorific value of wood pellets decreased along with the smaller size of the gelam wood powder (mesh). The addition of tapioca adhesive characteristics affect the physical properties of wood pellets, the higher the percentage of adhesive, the water content, volatile matter content, and ash content increase. Meanwhile, the addition of adhesive to wood pellets causes a decrease in carbon and calorific value.

Abstract

Corn oil may be one of the solutions to overcome biodiesel mixing as a substitute for fossil energy. In this study, we investigate the combustion characteristics of a mixture of corn oil with diesel oil. We used corn oil mixed with diesel oil using percentages 10%, 20%, 30%, 40%, and 50%. Characteristics of combustion were investigated by the time of ignition, visualization (height of fire and color of fire), flame temperature, and rate of combustion. The results show the highest ignition delay time is shown by a mixture percentage of 50%, which is 6,28 s. The flame of combustion has a yellow color. The highest flame was shown by the percentage of the mixture 10% that was as high as 66mm. The highest flame temperature in the percentage of 50% mixture with a temperature of 63,7°C. The highest combustion rate test results are shown by a 50% mixed percentage that is 0.849 s.

Abstract

Since plastic and food waste are both types of non-lignocellulosic biomass, these must be handled and managed correctly to avoid pollution problems and damage to the environment. Bio-oil, made from recycled materials, including plastic and food waste, is one focus of these attempts. The co-pyrolysis method is being investigated in this study as a technique of recycling plastic waste and food waste to produce biofuels with reduced environmental impact. In terms of energy efficiency, bio-oil is unequal to other fuels like coal or natural gas because of its high acidity, high oxygen content, and low thermal stability. Therefore, a vacuum distillation process is required to improve bio-oil quality by adjusting the distillation temperature from 300 to 350 OC and the percentage of plastic waste used from 30 to 50%. The bio-oil was analyzed using a Gas Chromatography-Mass Spectrometer (GC-MS). The general compound showed that acids (60%) and alcohols (20%) were the most prevalent chemical compounds, followed by phenol (4%), aldehyde (14%), aliphatic (5%), Furan (14%), and ketones (11%) at maximum temperature (350 oC) for 30-50% plastic waste. Meanwhile, the final product is affected by temperature and plastic waste (PET) ratio factors. At 350 °C and a plastic waste addition of 50%, the highest bio-oil yield is 45%.

Abstract

Sampah jumputan padat memiliki kadar air rendah selain itu sampah juga mempunyai nilai kalor cukup tinggi, setara dengan bahan bakar fosil seperti bensin dan solar. Untuk itu, penanganan sampah jumputan padat yang efektif adalah dengan memanfaatkannya sebagai bahan baku energi alternatif, salah satunya adalah dibuat pellet sampah jumputan padat yang dapat digunakan sebagai bahan bakar co-firing boiler pada PLTU dengan mengurangi pemakaian bahan bakar berbahan bakar fosil dari pembangkit listrik. Bank Sampah Urban Dewan di Barabai kabupaten Hulu Sungai Tengah saat ini berusaha untuk mengurangi polusi sampah dan membantu pengelolaan sampah sekitar menjadi sesuatu yang lebih berguna dan bernilai. Bank Sampah Urban Dewan dapat menjadikan potensi sampah yang telah dikumpulkan menjadi sesuatu yang bernilai ekonomis. Sehingga perlu adanya upaya untuk mengatasi permasalahan tersebut, yaitu dengan sosialisasi pemanfaatan, pengolahan, dan pembuatan pellet sampah jumputan padat serta hibah bantuan alat cetak pellet sampah jumputan padat. Dari kegiatan ini dihasilkan produk olahan yang lebih berkualitas dari sampah jumputan padat serta meningkatkan produktivitas dan pendapatan komunitas Bank Sampah Urban Dewan Barabai.
