Biobriket sangat potensial menjadi pengganti bahan bakar fosil yang mahal dan berdampak negatif terhadap lingkungan. Penelitian ini bertujuan untuk memahami karakteristik pembakaran biobriket yang terbuat dari campuran cangkang kelapa sawit yang telah mengalami torefaksi dan arang sekam padi. Cangkang kelapa sawit (CS) diproses pada suhu 250°C dan digiling halus sebelum dicampur dengan arang sekam padi (SP). Variasi rasio pencampuran kedua bahan tersebut dilakukan pada 70%:30%, 50%:50%, dan 30%:70%. Proses pencampuran menggunakan perekat kanji sebesar 15% (berdasarkan massa). Pembentukan briket dilakukan dalam tabung silindris dengan menggunakan 5 gram campuran untuk setiap briket, dengan tekanan kompaksi sebesar 0,85 MPa. Selanjutnya, briket dikeringkan selama 4 hari dalam ruangan terbuka sebelum diuji pembakarannya dalam sebuah reaktor. Pengujian pembakaran dilakukan pada 4 briket dalam sebuah reaktor dengan aliran udara ke biobriket sebesar 0,75 m/s. Selama proses pembakaran, dilakukan pengukuran terhadap perubahan massa dan temperatur. Pengukuran dilanjutkan hingga semua bahan terbakar habis. Hasil penelitian menunjukkan bahwa briket dengan komposisi 50:50 menunjukkan suhu pembakaran yang relatif stabil dan mencapai suhu tertinggi dibandingkan dengan komposisi lainnya. Laju pembakaran biobriket sejalan dengan peningkatan temperatur yang dihasilkan dari proses pembakaran

Penelitian ini bertujuan untuk menganalisis pengaruh komposisi perekat terhadap karakteristik termal briket arang pelepah sagu. Tiga komposisi yang diuji adalah briket dengan perbandingan presentase arang pelepah sagu:perekat tepung kanji masing-masing 90:10%, 80:20%, dan 70:30%. Pembuatan briket dilakukan pada tekanan konstan 70 kgf/cm2. Pengujian termal dilakukan menggunakan tungku pembakaran silindris yang dirancang untuk aliran udara secara alami. Setiap komposisi diuji dengan tiga briket. Selama pembakaran, penurunan massa dan peningkatan suhu ruang bakar diamati setiap interval waktu 4 menit menggunakan timbangan digital dan termokopel tipe K. Hasil penelitian menunjukkan bahwa komposisi dengan perbandingan 90% arang pelepah sagu dan 10% perekat tepung kanji menunjukkan kenaikan suhu pembakaran tertinggi. Hasil ini menunjukkan bahwa proporsi perekat tepung kanji yang lebih rendah dalam briket dapat meningkatkan efisiensi pembakaran

Tire production in Indonesia is increasing continuously in line with the increasing automotive industry. Along with that, the waste of used tires that are not used in the environment is increasing. So we researched the use of used tire pyrolysis oil as an alternative fuel. The purpose of this study was to determine how to produce fuel oil through the pyrolysis process of used motorcycle tires and to determine the combustion characteristics of the pyrolysis results of motorcycle-used tires. The method used in this research is an experimental method using a pyrolysis tool and data collection is carried out directly with various temperature variations. The research was conducted at temperatures of 250oC, 300oC, and 350oC to produce 202 ml, 280 ml, and 219 ml of pyrolysis liquid, respectively. The pyrolysis oil combustion test produced shows that the burning of used tire pyrolysis oil takes longer than the burning of kerosene in the same volume. Keywords: Tires, pyrolysis, temperature

Gasification is the process of converting energy from fuel containing carbon (solid or liquid) into a gas called syngas (synthesis gas). The purpose of this study was to determine the characteristics of syngas resulting from the gasification of a mixture of corn cobs and cashew shells and to determine the ideal composition of a mixture of corn cobs and cashew shells that produces optimal gas ingredients. The method used in this study is an experimental method by making a gasification tool and taking data directly with several variations of composition. The results showed that thecharacteristics syngas at the composition of 100% corn cobs could not produce flames, the mixture composition of 75% corn cobs and 25% cashew shells could not produce flames, at the composition of a mixture of 50% corn cobs and 50% cashew shells it was able to produce flames. flame, the composition of a mixture of 25% corn cobs and 75% cashew shells can already produce a flame and a composition of 100% cashew shells can also produce a gasification flame. Virtually the resulting flame is thought to be due to the presence of more hydrogen (gas) than carbon (smoke from combustion). The best composition in updraft gasification testing for corn cobs and cashew shells was obtained in a composition with a mixture of 25% corn cobs and 75% cashew shells, the resulting flame was obtained at 32.5 minutes to 50 minutes. Key words: Updraft gasification, composition , corn cobs, cashew shells, flame

So far, most farmers have drained agricultural products by drying directly under the hot sun. The drying process by drying directly requires intensive labor, longer time and requires a large amount of land. The purpose of this study is to find out the heat transfer analysis that occurs in rack type dryers that utilize moving air flow into the device naturally and then the air is heated by utilizing the heat of solar radiation collected at solar collectors and also utilizing biomass energy used to accelerate drying process of the product in the drying chamber. The data obtained were taken by using Thermocouple CC type (Cooper Constanta), Solar Powermeter, Anemometer, Thermo-Hygrometer and Scales. The results of the study that the heat transfer analysis on the rack type dryer with the drying process using solar collectors as heat absorbers and biomass energy then combined.

Torrefaction is a heat treatment of raw biomass to obtain a fuel that is more stable, has a high energy density and higher brittleness and is easy to grind. The purpose of this study is to determine changes in physical properties, calorific value of water absorption resistance (hydrophobic) in teak wood after the torrefaction process in the microwave. The method used in this study is an experimental method using a microwave heater equipped with measuring instruments such as a digital thermometer, and digital scales. The biomass material used was finished wood cut with sample sizes of Model 1 (cube 3 x 3 cm), Model 2 (rectangular 7 x 3 x 3 cm), and Model 3 (cylindrical tube 7 x 3 cm). Each material was put in a microwave depth for torrefaction for 15, 25, 35 minutes. The results showed that the model 2 sample experienced the largest mass change of 80.95%, followed by model 3 with a mass change of 76.47% and Model 1 which experienced a mass change of 70%. The longer you experience electromagnetic wave radiation in the microwave, the greater the mass change and the lower the water absorption Keywords: Torrefaction, teak wood, microwave, calorific value, moisture content
