Abstract

In general, the process of peeling coconut coir still uses a manual process with amachete or crowbar so that it requires a lot of manpower with special skills, long time,and sharp tools to peel coconuts, This research aims to produce the design of a coconutcoir peeling machine, which can help in the process of peeling coconut coir and separatecoconut coir from coconut shells. The method used in this study is the Pahl Beitzmethod which consists of four stages. First, compile product technical specifications tomeet the needs of the community. Second, look for several product concepts in the formof sketches or simple schemes. Third, give shape to the product concept so that theelements can compose the shape of the product. Fourth, determine product details suchas the arrangement of elements, shape, dimensions, surface smoothness, and material.From the results of this study, it was obtained that the drive motor was selected with apower of about 3 HP with a speed of 2200 rpm. For the chain system and sprocket, a chain number of 40 with a single frame was chosen. With the shaft diameter selectedØ20 mm for the drive motor and Ø25 mm for the peeling roller. The calculation resultsshow that the production capacity of coconut fiber peeling is 360 kg/hour, taking intoaccount the number of coconuts per session (10 coconuts), with the average weight ofcoconuts (1.5 kg), and the peeling time per session for (2 minutes).

Abstract

Preheating is carried out by heating around the welding point, before welding begins, which is called the preheating temperature. Stabilizing the sample temperature before welding is intended to carry out preheating to prevent damage and defects during and after welding. The aim of this research is to determine the effect of preheating temperature on the hardness value of SMAW welding results on the hardness test on Hardok 450 steel. The welding carried out was the SMAW method on Hardok 450 steel using a 60? V seam connection. The preating temperatures used in this research were 200?C, 300?C and 400?C. The results of SMAW welding are subjected to hardness testing. From the results of the hardness testing, the hardness value increases as the preheating temperature increases. The lowest hardness value was obtained at a temperature of 200?C with an average hardness value of 68.2 HRC in the HAZ (Heat Affected Zone) area and an average value for weld metal of 64.6 HRC. Meanwhile, the highest hardness value was obtained at a temperature of 400?C, the average hardness value was 77.8 HRC in the HAZ area, while the hardness value for weld metal was 67.3 HRC

Abstract

When renewable fuel energy is running out, many academics and practitioners are starting to try to make alternative fuels that come from renewable resources. To reduce our dependence on fossil fuels, this is very important to do, one of the renewable energies that has great potential in Indonesia in biomass. Biomass energy includes livestock, plantations, wood, and industrial and household organic materials. The aim of this research is to determine the characteristics of briquettes mixed with palm fruit and bamboo sticks. The best composition of a mixture of palm fruit and bamboo stems in this research was in sample 5 a mixture of 25% palm fruit : 65% bamboo stem with 10% adhesive had a water content of 11.17%, ash content of 57.59%, volatile matter content of 19.62%, bound carbon content 48.73% and heating value 4.288 cal/g.

Abstract

Pengelolaan sampah yang efektif dan ramah lingkungan menjadi tantangan utama dalam mengurangi dampak pencemaran udara. Insinerator merupakan alat yang umum digunakan untuk mengolah sampah, tetapi emisi gas buang yang dihasilkan dapat mencemari lingkungan jika tidak ditangani dengan baik. Penelitian ini bertujuan untuk memodifikasi sistem penyaringan asap pada insinerator sampah agar lebih ramah lingkungan dengan mengoptimalkan penyerapan gas berbahaya. Modifikasi yang dilakukan mencakup pemasangan filter air flow untuk menyerap gas beracun seperti karbon monoksida (CO), karbon dioksida (CO?), PM2.5, dan PM10. Selain itu, ditambahkan sistem penyemprot air (mist sprayer) untuk menangkap partikel halus yang tersisa. Pengujian dilakukan dengan membandingkan kualitas udara sebelum dan sesudah modifikasi menggunakan alat pengukur emisi gas buang. Hasil penelitian menunjukkan bahwa sistem penyaringan yang dimodifikasi mampu mengurangi emisi CO? hingga 33,33%, dan PM2.5 turun menjadi 50 µg/m³, di bawah batas standar kualitas udara. Modifikasi ini juga mempercepat proses pembakaran sampah basah dan kering sebesar 30 menit. Dengan adanya inovasi ini, insinerator sampah dapat beroperasi lebih ramah lingkungan dan lebih efisien.
