Abstract

The ODJG group (People in Mental Disorders) is a community group engaged in social activities: helping, guidance, and mental health rehabilitation for ODJG who have undergone psychiatric medical treatment from a Mental Hospital. To carry out its activities, this group formed a business that produces food and beverages (MaMin) made from Moringa leaves (moringa tea, instant Moringa, Moringa ice wax, Moringa yogurt, Moringa pudding, Moringa flower extract). where the products have been marketed in Malang and surrounding areas. However, the production process encountered several obstacles: the lack of production equipment, the lack of maintaining product quality and the health of the work environment, and the lack of marketing techniques. Community service (PkM) aims to increase partners' ability to produce quality, safe, dan healthy MaMin made from Moringa leaves. The methods used in solving partner problems: 1). Production equipment grants, 2). Excellent and safe production technique training (GMP and HACCP), 3). Marketing digital training (digital marketing), 4). Production and marketing assistance and consulting. The results of the PkM activity show that there is an increase in the knowledge and skills of partners in producing healthy and quality MaMin and marketing it with digital marketing media

Abstract

A major challenge in injection molding is the instability of mechanical properties in products due to suboptimal process parameter settings, which necessitates identifying the optimal parameter combination to achieve adequate tensile strength and hardness. This study aims to evaluate the effects of cooling time, injection pressure, and material type on the tensile strength and hardness of ballun insulator products produced by injection molding. Two thermoplastic materials, Polypropylene (PP) and High-Density Polyethylene (HDPE), were selected due to their different molecular structures and crystallization behavior, both of which influence mechanical performance. The materials were processed under varying cooling times (20, 25, 30, and 35 s) and injection pressures (24, 27, 30, 33, and 36 bar). The novelty of this study lies in the comparative evaluation of PP and HDPE under identical process conditions for ballun insulator applications. The results showed that higher injection pressure improved mold-filling and molecular chain compaction, leading to increased tensile strength, while longer cooling time promoted more controlled crystallization and improved surface hardness. PP exhibited higher tensile strength due to its stiffer molecular structure, achieving a maximum tensile strength of 0.031 MPa at 36 bars. In contrast, HDPE showed higher hardness due to its denser crystalline structure, reaching 69.75 HD at 35 s cooling time. These findings indicate that material-specific optimization of injection molding parameters is important for achieving consistent mechanical properties and dimensional stability in ballun insulator products.

Abstract

Kinerja lampu utama yang memadai merupakan faktor penentu keselamatan berkendara sepeda motor, terutama pada malam hari, dan regulasi di Indonesia sesuai pp No. 55 tahun 2012. Teknologi bi-LED projector yang kian populer menawarkan sumber cahaya yang terarah dan hemat energi. Namun, produk yang beredar di pasaran memiliki variasi diameter lensa dan spesifikasi arus yang berbeda-beda, sehingga memunculkan asumsi umum bahwa lensa terbesar dan arus tertinggi selalu memberikan hasil terbaik. Penelitian ini menganalisis secara eksperimental pengaruh variasi diameter lensa dan arus listrik secara bersamaan terhadap intensitas cahaya dan temperatur kerja lampu bi-LED projector yang terpasang pada sepeda motor Honda Supra X125. Rancangan faktorial dua arah digunakan dengan mengombinasikan tiga diameter lensa (2, 2,5, dan 3 inci) dan tiga level arus (2, 4, dan 6 A), masing-masing diuji sebanyak tiga kali pengulangan. Data kemudian diolah menggunakan Two-Way ANOVA dan Response Optimization pada perangkat lunak Minitab. Hasil penelitian menunjukkan bahwa arus listrik dan diameter lensa sama-sama berpengaruh signifikan terhadap intensitas cahaya (P = 0,000), sedangkan terhadap temperatur hanya arus listrik yang berpengaruh signifikan (P = 0,000), sementara diameter lensa tidak berpengaruh signifikan (P = 0,311). Intensitas cahaya tertinggi, yaitu 112.676,74 cd, tercatat pada kombinasi lensa 3 inci dan arus 6 A, tetapi hasil optimasi menunjukkan bahwa kombinasi lensa 3 inci dengan arus 4 A merupakan titik kerja terbaik, yaitu menghasilkan 86.795,2 cd pada temperatur yang lebih aman sebesar 33,83°C dengan nilai composite desirability 0,642. Temuan ini menegaskan bahwa memadukan lensa berdiameter besar dengan arus menengah lebih menguntungkan dibandingkan dengan memaksimalkan arus semata, karena tetap jauh melampaui ambang regulasi, sekaligus membatasi thermal droop dan menjaga keawetan chip LED.

Abstract

The COVID-19 pandemic has had a significant impact on Indonesia's economy, with reduced purchasing power and job losses, highlighting the need for the strategic role of Micro, Small, and Medium Enterprises (MSMEs) in economic recovery. In Mulyoagung Village, East Java, cassava cracker MSMEs face challenges in increasing production capacity due to traditional drying methods that depend on sunlight, which is unreliable during the rainy season. This study proposes the adoption of a drying oven technology as a solution to enhance production efficiency and capacity. By implementing this technology, the production of cassava crackers increased from 200 kg/day to 500 kg/day, a 2.5-fold improvement. Additionally, the study addresses the administrative issues within MSMEs, specifically the lack of structured financial record-keeping. Through training in financial management and the use of break-even point (BEP) analysis, MSMEs were able to improve their financial tracking and decision-making processes. The combination of technological improvement and better administrative practices not only boosted production but also improved the competitiveness of the MSMEs in local and regional markets. This project demonstrates the importance of applying appropriate technology and effective management to overcome operational challenges and foster long-term business sustainability.

Abstract

Welding parameters strongly influence the mechanical integrity and metallurgical quality of welded joints. Shielded Metal Arc Welding (SMAW) is valued for its ease of use and versatility across various materials. This study investigates the effect of welding angle variations on the impact strength, microstructure and macrostructure of AISI 1020 steel joints welded using SMAW technique. Welding was performed at angles of 45° and 70° using currents of 80, 90, and 100 A. Charpy impact testing was conducted in accordance with ASTM E23, while macrostructural and microstructural observations were used to evaluate weld quality and the Heat-Affected Zone (HAZ). Impact testing evaluated the internal toughness of the welded joints, while structural observations provided insights into the weld quality and integrity. Results indicated that higher welding currents and larger angles significantly improved impact resistance. The highest impact energy (56 J/cm²) was obtained at 100 A and a 70° welding angle, showing the best impact resilience. The macro and microstructural analysis supported this, with fewer cracks and more evenly distributed martensite, indicating better weld quality.

Abstract

Material selection is crucial for ensuring the structural reliability of hydraulic actuator cylinders operating under high-pressure and dynamic loading conditions. Conventional methods, which focus on cost or manufacturing ease, may neglect detailed performance analysis, leading to local stress concentrations exceeding material strength. This research addresses this issue by comparing the performance of AISI 1020, AISI 1035, and AISI A2 tool steel using Finite Element Analysis (FEA) and conducting experimental testing to assess displacement, Von Mises stress distribution, and safety factor under various loads (450 N, 900 N, and 1350 N). The experimental results show that AISI A2 performed best in structural response with the highest safety margin, AISI 1035 exhibited the highest stress, and AISI 1020 exhibited the highest displacement. In FEA, AISI A2 showed a controlled maximum displacement of 0.28 mm with a safety factor of 3.94, compared with AISI 1020, which reached 0.82 mm and a safety factor of 1.23. The findings support the significant influence of material mechanical properties on actuator structural integrity and confirm that AISI A2 provides the highest resistance to deformation and stress concentration. The study demonstrates the effectiveness of FEA in optimizing actuator material selection for high-load applications.

Abstract

Heat Treament process has experiencing progress driven by improvements in science and technology. The heat treatment process has the aim to form the properties of metals with different work to be achieved in accordance with the objectives being made, heat treatment can also be used to change certain useful properties or for specific purposes for manufacture, such as: escalating machine ability characteristic, restoring the elasticity after cold work operations. The Purpose of the study to determine the effect of carbon equivalent and viscosity of cooling oil on the microstructure and hardness of steel in the hardening process. The method of the study is by doing a hardening process on the specimen with the temperature according to the thickness and composition of specimen. Then the cooling process is done using SAE 10 oil, SAE 40 oil, and SAE 90 oil. Then micro photo testing and hardness test are done with Vickers. The results of the study are, the carbon equivalent equivalent to violence results in a carbon equivalent value that has a significant effect on response because the P-value is smaller than alpha (P-value <α). On the influence of the cool oil viscosity to the hardness, the oil viscosity results have a significant effect on the response because the P-value is smaller than alpha (P-value <α). Whereas the interaction between variations in carbon equivalent and the viscosity of the coolant oil does not significantly influence the response because the P-value is greater than alpha (P-value> α). For the highest average hardness value on VCN 150 using SAE 10 oil at 486.5 HV and the lowest using SAE 40 oil at 450.7 HV, while on S45C steel the highest hardness using SAE 10 oil at 276.5 HV and the lowest hardness using SAE 40 oil is 249.7 HV. In the analysis of micro carbon equivalent structure and oil viscosity which has the highest average hardness value because it has a dominant martensitic structure. Whereas specimens that have ferrite structure still dominate compared to martensite which have the lowest mean hardness value.

Abstract

properties and rapid combustion. However, optimizing the performance of dry cell HHO generators remains a significant challenge. This study investigates the effect of varying electrode materials (copper and stainless steel), electric current, and NaOH concentration on HHO gas production. The key performance indicator used is the flow rate of HHO gas produced. Results show that increasing electric current significantly enhances HHO production, though this relationship is non-linear due to the rise in electrolyte temperature and internal resistance. A higher NaOH concentration increases electrolyte conductivity, improving HHO production, but excessive concentrations can lead to higher temperatures and electrode degradation. Copper electrodes outperformed stainless steel in gas production due to better electrical conductivity, while stainless steel exhibited superior corrosion resistance over time. Optimizing the combination of electrode material, current, and NaOH concentration is crucial for enhancing the performance of dry cell HHO generators, offering valuable insights for hydrogen-based energy systems.

Abstract

In the automotive world, power reduction in long-used motorcycles is a common issue that can affect vehicle performance. Over time, engine components experience wear and decreased efficiency, leading to reduced power output. One solution to address this problem is optimizing ignition settings by upgrading the CDI (Capacitor Discharge Ignition) and replacing the standard coil with an aftermarket coil. Upgrading the CDI and replacing the standard coil with an aftermarket one aim to improve engine power, as the standard CDI has a relatively low output and the standard coil has a limited output capacity. Therefore, the coil must match the output capacity of the upgraded CDI. This study aims to enhance the performance of a 110cc four-stroke engine. The study method used is a quantitative experimental approach, and data processing is carried out using two-way ANOVA analysis of the test results, processed in Microsoft Excel, with the average results taken from three trials per variation. The independent variables in this study are the racing coil with a voltage greater than the standard (up to 90 kV) and ignition timing mapping with a programmable CDI, while the dependent variable is power. The results of the study show that the ignition timing set at 13 degrees and the use of the BRT coil provided the highest power output, reaching 8.33 horsepower at 8000 rpm. This outcome is due to the critical role of ignition timing in controlling fuel combustion in the combustion chamber, where an earlier explosion with a larger spark results in higher power output
