Abstract

Proper handling of biomass waste can turn waste into something beneficial for society. One way that can be done is to convert biomass waste into quality biochar for energy needs and agriculture as a planting medium. This partnership program is intended to provide education and practical knowledge to the community regarding utilizing biomass waste for biochar production using a double tube reactor. The activities consisted of socialization of the impact of the abandonment of biomass and the benefits of biomass for household energy needs, as well as practical experience of carbonizing biomass by directly involving partner communities. This activity was carried out at Pambulaan Jaya Village Hall attended by 32 community partners and 9 teams from Halu Oleo University. This partnership activity is very relevant for people in the village where most of the population lives as rice and field farmers. The practical knowledge on carbonizing biomass waste was conducted in two days for the two types of biomasses, namely wood chips and coconut shells. The community was very enthusiastic about continuing the carbonization process after they learned about the great benefits of this biochar product for household energy needs, growing media for plantations, and increasing their income.

Abstract

This research aims to investigate the value of thermal conductivity of a composite material made from Polyester Resin (R), Aren Fiber (I) and a some water and epoxy. Composite materials used in this work have been made based on the ASTM C177. Experimental apparatus used in this study consists of a source of heat (150 Watt), thermocouple, digital balance and stopwatch. The main materials on this study consist of the three variations of composition, 40%, 50% and 60% I/R (by volume) respectively. This work begins with preparation of the three specimen materials of each composition. All specimen have been made in 30cm x 30cm x 1 cm size of length, width and thickness, respectively, and investigated the properties of the composites at several spatial and time during applied some energy source. Investigation was conducted at ambient temperatures and pressure at each 1 minute for 120 minute of heating. Density of each composites composition was also measured for the same size of all specimen of 5cm x 5cm x 1cm with standard ASTM C 2005, respectively. The results of the study show that the properties of the composite material varies with material-based compositions. The higher the Resin the better the thermal conductivity of the composites. Volume fraction of 40% I/R has thermal conductivity (k) of 1.235 W / m ° C, volume fraction of 50% I/R has thermal conductivity of 1.129 W / m ° C and volume fraction of 60% I/R has Thermal conductivity of 1.077 W / m ° C. The density of the specimens of the volume fraction of 40%, 50% and 60%I/Ris 1177.962 kg / m³, 1155.386 kg/m³ and 1144.662 kg/m³ respectively. The result of analysis also shows that composition of 60% I/R seems to be the appropriate material isolator using in many engineering applications based on the lower thermal conductivity and lower density.

Abstract

Penelitian ini difokuskan untuk perbaikan kualitas biomassa limbah kayu jati melalui proses torefaksi microwave dan mengamati parameter penting untuk meningkatkan densitas energi dan energy efisiensi dari bahan baku dalam menghasilkan bioarang berkualitas. Pengujian ini dilakukan dalam sebuah tabung reaktor 250 mL yang diletakkan dalam pemanas microwave dengan mengalirkan gas inert dan non-inert. Pemanas microwave yang digunakan beroperasi pada frekuensi 2,45GHz dengan variasi daya masing-masing 540W, 720W, dan 900W. Selama proses torefaksi gas nitrogen (inert) dialirkan ke dalam reaktor dengan Laju 0,125 mL/min dan untuk media udara (non-inert) dialirkan secara alami. Pengamatan terhadap temperatur dalam reaktor dilakukan setiap kenaikan 0.5 menit selama 20 menit menggunakan termokopel Type-K. Perubahan massa dan sifat produk torefaksi diamati dan dianalisis untuk memprediksi korelasi kenaikan nilai kalor, massa dan energi tersisa dengan daya operasi pemanasan microwave. Hasil penelitian menunjukkan bahwa dengan meningkatnya daya operasi torefaksi microwave maka nilai kalor dan densitas energi bahan produk meningkat signifikan sedangkan massa sisa dan energi tersisa cenderung menurun. Media udara sangat potensial sebagai pengganti gas nitrogen yang mahal untuk melakukan torefaksi microwave biomassa kayu jati.

Abstract

This study is designed to analyze the flow characteristics aver a square body with variations in the angle of attack of the flow. The force components u, CD, -CPb, CL and St are analyzed numerically. The method used in this research is the Large Eddy Simulation (LES) turbulent model with variations in the angle of incidence of fluid flow on a square test geometry model with cross-section height H = 40 mm (D = H). The results showed that the large angle of incidence of the flow increased the value of CD, CL due to the enlargement of the flow in the downstream wake area. While the CP value also decreased due to the negative pressure gradient of the downstream area enlarged with an increase in the value of the angle of attack of the flow. The angle of attack increases the parameters CDmax = 2.33, CP = -1.87, and St = 0.09 at an angle of -30° while at an angle of 0° the value of CD = 2.05 -CPb = -1.37, St = 0.128. Changes in the angle of incidence of the flow affect the frequency of vortices. The local velocity component (u) decreased.

Abstract

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
