<![CDATA[Scaling silika merupakan masalah utama dalam proses pemanfaatan energi panas bumi. Scaling silika paling banyak terjadi pada PLTP dengan karakteristik reservoir yang memproduksi fluida 2-fasa. Pilot Testing diperlukan untuk mengetahui parameter dan teknologi yang optimal dalam memitigasi scaling silika. Production Optimization Unit (POU) merupakan unit untuk melakukan pilot testing. Penentuan parameter operasi POU menggunakan simulasi (test planer) secara general dengan algoritma yang terkunci dan tingkat keakuratannya masih rendah. Penelitian ini bertujuan untuk melakukan pengembangan simulasi pada parameter suhu jalur injeksi brine di POU dengan menggunakan prangkat lunak EES dan melakukan verifikasi hasil simulasi dengan hasil pengoperasian POU secara eksperimental. Metode penelitian yang digunakan pada penelitian ini adalah kuantitatif komparatif, atau membandingkan secara langsung data hasil simulasi dan eksperimen untuk memverifikasi. Berdasarkan perbandingan data verifikasi simulasi, pengembangan simulasi berhasil meningkatkan akurasi sebesar 6.471%. Algoritma yang dibuat bersifat fleksibel sehingga engineer PT.XYZ dapat leluasa melakukan rekayasa algoritma dan parameter. Rekayasa diperlukan guna mendapatkan parameter-parameter yang optimum sebagai dasar pengoperasian POU.]]>

<![CDATA[Chassis is the most important part of the vehicle. The purpose of the Chassis is to get optimal results between the size of the Chassis and the level of Safety Factor that is qualified in order to support the needs of the prototype "Warak" The chassis is designed using a ladder frame type frame design because this type is simple but sturdy to support the load. Design chassis uses Software Autodesk Inventor 2023 to get optimal results and uses Square Hollow Aluminum 6061 type material. The use of the Frame analysis feature which is equipped with the Finite Element Analysis (FEA) method plays an important role in knowing indications of discrepancies in the prototype that has been designed in the form of VonMises Stress, Displacement, and Safety Factor. After going through the design stage, the overall dimensions of the prototype "Warakâ Stress Analysis obtained the maximum stress of Von Mises Stress which occurred in the chassis of 192.408 MPa. While displacement the maximum chassis is 1.7401 mm and the safety factor obtained from the analysis is a minimum of 1.08.]]>

<![CDATA[In recent years, the additive manufacturing process has developed rapidly especially in the FDM process. One of the developing FDM processes is the mixing of two filaments, namely the layer by layer technique. The technique of mixing two filaments by layer by layer is a mixing technique with the concept of layers on one specimen. The aim is to find out the strength properties of the filaments as a result of mixing layer by layer. The results of previous studies show that the mechanical properties of PLA and ABS materials are highly dependent on the level of speed and the effect of printing speed. However, to obtain the appropriate alloying results from PLA and ABS, further research is needed to adjust the parameters of the PLA and ABS alloys. so that it is expected that the layer by layer mixing technique is able to produce better mechanical properties than PLA and ABS.]]>

<![CDATA[Currently the use of motorcycles is increasing from year to year in Indonesia. The need for bicycles is increasingly important because its means of transportation, to make easier for users to carry out their daily activities. The existence of motorbikes in Indonesia is very important because they have several factors, namely having great power and fuel economy. Besides that, modifying motorbikes is one of the hobbies of Indonesian people with one of the reasons being the condition of the track in Indonesia. Modifying motorbikes is done by adding parts or changing the original components to get maximum results. Therefore, based on these problems, this research was conducted to test the performance of the vario motor for standard and modified CDI ignition systems. This test uses 2 types of fuel, namely pertalite and Pertamax. The measurement results from this study are using a dynamometer to measure various variations of engine speed to obtain motor power and torque. Based on research data, it was found that CDI modifications 1 and 2 with pertalite and Pertamax fuel had an influence on engine performance. Then for better results, namely the modification 2 CDI test with Pertamax fuel with the maximum power produced, namely 7.7 HP and 8.6 Nm of torque.]]>

<![CDATA[Failure studies on the F4.04 milling machine cutter that frequently occur in the manufacturing industry have been conducted using applied failure analysis and repair methods. This study aims to analyze the damage to the F4.04 milling machine cutter and carry out repairs according to existing standards. The analysis of the root causes of damage and appropriate repairs is expected to enhance efficiency, productivity, and reduce production costs in the manufacturing industry. This analysis describes the results of visual observations of damage to the cutter in the form of fractures at the edges and surface wear. Fractures at the cutter edges appear irregularly, caused by excessive cutting loads. Excessive cutting loads result from improper feed speeds and excessive cutting depths. Process instability also contributes to cutter damage. Excessive vibration in the milling machine generates impacts or collisions that damage the cutter and accelerate wear. Excessive cutting loads and cutting instability are initiated by damage to bearing components and the use of non-standard V-belt sizes. This study provides a better understanding of the types of cutter damage and influencing factors, which can be utilized to enhance cutting efficiency and cutter lifespan. It is expected that this study will contribute to identifying the exact causes of damage and designing appropriate repairs, thereby improving production quality, and reducing the risk of damage to F4.04 milling machines in the future.]]>

<![CDATA[Belt conveyor is one of the transportation media used to move material in the form of units or bulk spills from one operating system to another. At PT Solusi Bangun Indonesia, one of the belt conveyor is used to alternately transport two types of materials, namely fly ash & bottom ash (FABA) and silica. It causes inconsistent bin filling when the consumption of silica and FABA materials is high at the same time. In addition, problems with the FABA belt conveyor drive system often occur, such as tripping motors, broken chains, and worn sprockets, causing FABA transport to be disrupted. Therefore, it is necessary to modify the belt conveyor drive system so that FABA transport becomes smoother. The methode begins with collecting data in the field or information from supervisors, field studies, carrying out the design process to evaluating the results. The modifications made were by replacing the gearmotor with a power of 11 kW with a rotational output 24 rpm, changing the transmission system from chain-sprocket to a coupling, and increasing the diameter of the head pulley from 478 mm to 560 mm to increase the belt conveyor transport capacity to 125 tons per hour.]]>

<![CDATA[Stabilitas forklift masih menjadi salah satu perhatian terbesar hingga saat ini, masih banyak kasus kecelakaan yang disebabkan hilangnya stabilitas saat forklift membawa beban. Berbagai penelitian terkait stabilitas forklift telah dilakukan namun belum membahas terkait dengan stabilitas forklift dalam kondisi dinamis. Dalam penelitian ini akan dianalisa kestabilan forklift dalam kondisi statis yaitu diam dan kondisi dinamis terhadap pengereman.. Model forklift yang menjadi obyek penelitian ini adalah Forklift TCM FD25T3Z dengan variasi beban dan kecepatan. Analisa dilakukan untuk mengetahui massa beban maksimum yang dapat diterima forklift dan pengaruh massa beban terhadap kestabilan forklift dalam kondisi diam dan dalam kondisi pengereman. Hasil analisa menunjukkan forklift akan terjungkal apabila mengangkat beban 3380,67 kg atau dengan penambahan 35,2% dari beban maksimum Operation Maintenance Manual (OMM) yaitu 2500 kg. Kestabilan forklift dalam kondisi statis jika dilihat dari nilai gaya kontak roda dengan tanah dan posisi Combined Center Gravity (CG) massa beban berpengaruh terhadap kestabilan forklift. Kestabilan forklift dalam kondisi dinamis jika dilihat dari jarak pengereman kritis yang menyebabkan forklift tidak stabil dipengaruhi oleh penambahan beban dan kecepatan. Semakin tinggi kecepatan dan semakin besar beban, semakin jauh pula jarak pengereman yang diperlukan untuk menghentikan forklift.]]>
