Analisis Optimasi Cetakan Briket Sistem Hidrolis Menggunakan Pendekatan Finite Element Method
Full text linkThe briquette mold is a critical component in the manufacturing process of the hydraulic briquette molding machine. Improved mold design can increase production efficiency and quality. The finite element method simulates the structural response of the briquette mold to hydraulic pressure. An accurate mathematical model is built based on material parameters, mold dimensions, and hydraulic load characteristics. The influence of mold design variables such as geometry, materials, and internal configuration can be evaluated in detail by applying FEM. Mold optimization uses a numerical optimization algorithm to find a combination of mold parameters that provides the best structural response. The main goal of mold optimization is to increase mold durability, reduce deformation, and minimize the potential for structural failure. The optimization process is integrated with FEM analysis to achieve the optimal mold solution. Improved mold design resulting from this optimization makes a positive contribution to the efficiency of hydraulic briquette production and reduces the potential for mold damage. The results of this research by optimizing the design of the length of the rod, length of the mold, height of the central protrusion of the press, and changing the diameter of the mold, we obtained simulation results that show an even distribution of loads shown in the same color. In this study, the total deformation value was 5.0298 x 10-6 mm and the equivalent elastic strain was 3.4972 x 10-10 m

Analysis Of Water Harvester Machine Performance Using Single-Sided Thermoelectric Cooling
Full text linkThis study addresses the urgent issue of global water scarcity, particularly in arid regions with limited access to conventional water sources. The performance of a water harvester equipped with single-sided thermoelectric cooling technology is evaluated to enhance water collection efficiency from the atmosphere. The primary objective of this research is to optimize the machine's performance by varying fan speeds and analyzing its impact on collected water volume. The methodology involves experiments conducted at three different fan speeds: 1000 RPM, 1500 RPM, and 2000 RPM, with each speed tested for three hours and data collected every 30 minutes. The observed variables include collected water volume, air temperature, and humidity. Results indicate that water collection efficiency increases with higher fan speeds, with 2000 RPM yielding the highest volume. However, efficiency declines after 90 minutes, mainly influenced by fluctuating external factors such as temperature and humidity. Additionally, increased fan speeds may result in higher energy consumption, which is a consideration for developing more energy-efficient machines. The study recommends further development to integrate automatic control systems capable of adjusting fan speeds based on environmental changes in temperature and humidity. The conclusion of this research is that thermoelectric cooling technology has significant potential for water harvesting, yet sustainable innovations are necessary for adaptation across diverse environmental conditions

Studi Eksperimental Pengaruh Jarak Tempuh Dan Temperatur Udara Sekitar Terhadap Penurunan Nilai Viskositas Oli Mesin Pada Engine 125 CC
Full text linkThere are various types of motorbike oil, riders can choose oil according to their needs. This experiment aims to find out which oil is suitable for use by a 125 cc engine at different air temperatures according to the driver's needs. This experiment will analyze the reduction in oil viscosity values with brands of oil A, oil B and oil C. The mileage used is 20 km, 40 km and 60 km with air temperatures of 33-36°C and 28-30°C. The viscosity value was measured using a Brookfield viscometer. Based on the results of the tested data, the percentage reduction in viscosity value at an air temperature of 33-36°C with a distance of 60 km is Oil A 26%, Oil B 62%, and Oil C 19%, therefore Oil C is better used in areas with a temperature of 33-36°C because it does not experience a significant decrease in viscosity. The percentage reduction in viscosity value at an air temperature of 28-30°C with a distance of 60 km is oil A 11%, oil B 62%, and oil C 62%, so oil A is better used in areas with a temperature of 28-30°C
Studi Kasus Pengembangan Energi Surya Sebagai Stimulus Ekonomi Hijau 2045
No full textTo face the planetary crisis, Indonesia has prioritized sustainable development through the use of green economy practices to reduce future carbon emissions. Solar energy as one of the renewable energy sources has greater value than others, but its utilisation is still small. Consideration of this condition is discussed with the aim of evaluating the progress of the green economy; finding problems; providing solutions and suggestions for Indonesia's future development. The research method uses a systematic quantitative descriptive approach based on data collected through observations, interviews and questionnaire surveys from resource persons by providing 3 leverage factors namely; funding, regulation and institutions. The study results show that the regression coefficient of the funding factor variable (X1) is 0.365 and positive, then the funding factor variable (X1) has the largest coefficient compared to the coefficient of the regulatory factor (X2) and the institutional factor (X3), so that the funding factor is the most dominant factor in measuring the performance of solar energy success towards the implementation of the green economy. Without serious support from the government in terms of funding readiness, development goals will not be achieved, due to the large amount of funds needed to support the development of the Green Economy. However, the three variables are mutually sustainable by making policies and legal foundations to fulfil the funding needs of the green economy, regulations will be the foundation in mainstreaming the implementation and funding of green economy policies. Green economy planning, governance and supervision are supported by mature institutions and fund
