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

Waste is a residual production material that contains substances capable of causing pollution and health disturbances. One of the waste types frequently encountered is cigarette filter waste and wood powder waste, both of which are managed minimally. This research aims to determine the influence of the composition of a mixture of cigarette filter waste and wood powder waste on sound absorption in composite materials. The method involved preparing the necessary tools and materials, then creating composites with fractions (65%, 20%: 10%, 15%), (60%, 20%: 13%, 7%), and (55%, 20%: 15%, 10%). Subsequently, sound absorption testing was conducted using the direct method following ISO 11654 standards. Results from the sound absorption testing at a frequency of 500 Hz showed the highest sound intensity value in the fraction (65%, 20%: 10%, 15%) at 104,833 dBa and the lowest in the fraction (55%, 20%: 15%, 10%) at 93,333 dBa. The highest sound absorption coefficient value was found in the fraction (55%, 20%: 15%, 10%) at 0,202, while the lowest was in the fraction (65%, 20%: 10%, 15%) at 0,104. As the volume of acoustic material from cigarette filter waste and wood powder waste increased, the sound absorption coefficient also increased. The best sound absorption coefficient value was observed in the fraction (55%, 20%: 15%, 10%) at 0,202

The machining process is a manufacturing process where the main process is removing or removing some of the material from a basic material which can be in the form of a shaft so that it meets the desired shape and quality. The purpose of this study was to determine the effect of the rotational speed of the lathe spindle on the value of Unit Horse Power (UHP) in the low carbon steel turning process. The study used carbon steel material in the form of a cylinder with an initial diameter of 40 mm and a length of 150 mm. The cylindrical workpiece is turned with a depth of 1 mm at various speeds, namely 95 rpm, 130 rpm and 180 rpm. The results showed that the rotational speed of the lathe spindle affects the value of the unit horse power (UHP). The higher the spindle rotation of the lathe, the greater the UHP obtained, where the highest UHP occurs at 180 rpm with a UHP value of 0.00030 and the lowest UHP. found in round 130 with a UHP value of 0.00016. High rotation causes a large force so that the vibration of the lathe tool is even greater.Keywords: Lathe process, carbon steel, spindle rotation.

This study aims to determine the effective shaft diameter in the design analysis of polishing machines in the manufacture of camshaft, determine the suitability of the V-belt, determine the service life of the bearing, determine the ability to accept seat loads. The method used in this research is the literature review method, namely by analyzing the primary data of the components of the tool to get the values that occur in the tool. The results of the calculation of the shaft suitability analysis obtained a suitable shaft with a diameter of 13 mm which has a rotational deflection smaller than the deflection limit of 0.061o < 0.3o. Based on the calculation of the V belt, size of the V belt selected is on the market, namely the V belt type A No. 37 with a length of L = 940 mm. From the calculation results, bearing is having a lifespan of 2603.838 hours. The strength analysis of the camshaft holder using the DS Abaqus software was found not to exceed the allowable deflection limit, namely: 2.736e-09 mm <0.417mm considered safe to be used. Meanwhile the analysis of the sandpaper seat is still lower than the limit’s value or 1.786e-09 mm < 0.694mm. Thus, the sandpaper holder is said to be safe in resisting the working forces.Kata kunci: camshaft, modification, shaft, v belt.
