Biopellet is a type of solid fuel based on biomass waste which has a smaller size than briquettes. The purpose of this study was to determine the effect of adhesive composition and the effect of the diameter of biopellet briquettes on the characteristics and temperature and combustion time of the gasification stove. The method used was a mixture of 40% sawdust biomass and 60% coconut shell charcoal by varying the adhesive as much as 20%, 25%, 30% on 4 mm and 7 mm diameter biopellet briquettes. Based on the test results, it is known that the adhesive composition affects the temperature and time produced during combustion. The highest temperature reached 713.20C with an adhesive percentage of 20% at a diameter of 7 mm biopellet briquettes with a flash time of 26 minutes. While the lowest temperature reached 653.00C with 30% adhesive percentage on 4 mm diameter biopllet briquettes and 30 minutes of flame time. For the characteristics of biopellet briquettes from laboratory tests, the highest moisture content value was 8.10% in 30% adhesive at 4 mm diameter for the highest ash content value 9.45% at 30% adhesive variation at 4 mm diameter and the highest calorific value reached 4571.64 cal/g of 20% adhesive vari at 7 mm diameter.

Komposit merupakan material yang terbentuk dari kombinasi dua atau lebih material, sehingga dihasilkan material yang mempunyai sifat mekanik dan karakteristik yang berbeda dari material pembentuknya. Bahan komposit memiliki banyak keunggulan diantaranya: berat jenisnya, kuat, tahan korosi, dan memiliki biaya pembuatan yang lebih murah. Bahan komposit terdiri dari dua jenis, yaitu bahan komposit partikel dan bahan komposit serat [1]. Batang pisang dari limbah perkebunan pisang dipotong dengan ukuran 25 cm supaya proses pengambilan serat yang lebih mudah. Batang pisang dijemur hingga kering sebelum diambil seratnya, hal ini dilakukan agar kadar air yang ada di batang pisang hilang dan supaya mudah pada saat pengambilan serat. Batang pisang disisir menggunakan sikat kawat untuk memisahkan antara serat dengan partikel partikel-partikel yang ada pada pelepah pisang. Serat yang sudah terpisah kemudian dijemur dalam waktu 2-3 hari, tetapi penjemuran dilakukan tanpa kontak langsung dengan sinar matahari. Nilai hasil uji rata-rata kekuatan tarik dari komposit serat batang pisang raja (19,88 N/mm2), pisang kepok (25,46 N/mm2), pisang raja sereh (15,02 N/mm2) dan pisang jantan (22,96 N/mm2). Dapat diketahui bahwa komposit serat batang kepok memiliki nilai kekuatan tarik yang paling besar dengan nilai hasil uji rata-rata 25,46 N/mm2. Nilai hasil uji rata-rata kekerasan dari komposit serat batang pisang raja, pisang kepok, pisang raja sereh dan pisang jantan adalah 98,6 HRR; 83,4 HRR; 96,5 HRR; dan 101,75 HRR. Dapat diketahui bahwa komposit serat batang pisang jantan memiiki nilai kekerasan yang paling tinggi dengan nilai hasil uji rata-rata 98,6 HRR. Tinggi rendahya nilai hasil uji rata-rata kekerasan dan kekuatan tarik komposit serat batang pisang dapat dipengaruhi oleh besar kecilnya serat yang dimiliki oleh batang pisang, susunan serat dan adanya void (kekosongan) pada masing-masing komposit serat batang pisang. Untuk pengujian tarik didapat nilai terbesar pada serat batang pisang kepok dengan nilai 25,46 N/mm2. Kemudian untuk pengujian kekerasan didapat nilai pengujian terbesar pada jenis batang pisang jantan dengan nilai kekerasan 98,6 HRR

The calorific value contained in the fuel is one of the benchmarks for the quality of the fuel. To test the calorific value of fuel, a test device such as a bomb calorimeter is needed. The performance of the calorimeter bomb is influenced by the heat absorbed by the water media and the heat wasted into the environment and the heat from the combustion that occurs in the combustion chamber (reactor). Combustion in a bomb calorimeter is affected by the rate of air flow used. The wasted heat to the environment can be minimized by using an insulator on the outer wall of the calorimeter bomb. The purpose of this study was to determine the effect of air flow rate and type of insulator on combustion temperature, heat transfer and accuracy of bomb calorimeter test results. The method used in this research is experimental research by making and testing bomb calorimeters using variations in the air flow rate in the combustion process, namely 40 m/s, 50 m/s and 60 m/s and the types of insulators are air and Fiber glass wool. From the results of the research that has been done, it can be concluded that the air flow rate and the type of insulator affect the combustion temperature, heat transfer and accuracy of the bomb calorimeter. The maximum combustion temperature is 480 °C to 490 °C, heat transfer is 77.7 watts and the highest bomb calorimeter accuracy is 98% obtained at variations in air flow rate of 60 m/s and Fiber glass wool insulator.

In this modern era, the problem of packaging has become a part of everyday people's lives, especially in relation to food products. Cup drink MSME business actors have started using labels to market and create a special attraction for their products. At this time cup printing has begun to use machines, but the machines commonly used are only capable of printing one color and cannot print two or more colors and the price of the machines is still quite expensive. The purpose of this research is to optimize and redesign a one-color cup screen printing machine into a cup screen printing machine design that is practical and capable of printing two or more colors, to determine the power consumption of the electric motor on a two-color cup screen printing machine, and to determine the capacity and production yield of cup screen printing machines. two colours. The research method used was experimental by designing and manufacturing and testing a semi-automatic two-color screen printing device.
