Abstract

Suhu mesin yang tinggi pada sepeda motor sangat memengaruhi performa dan umur komponen, terutama piston dan dinding silinder. Sistem pendinginan oli yang kurang optimal dapat menyebabkan temperatur oli meningkat dan berisiko menimbulkan overheating. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan oil cooler terhadap suhu mesin pada sepeda motor 4 langkah 115 cc. Metode yang digunakan adalah eksperimen dengan membandingkan suhu mesin sebelum dan sesudah pemasangan oil cooler. Pengukuran dilakukan dalam kondisi operasional yang sama untuk mengetahui efektivitas oil cooler dalam menurunkan suhu mesin pada setiap tingkat putaran. Persentase penurunan suhu tercatat sebesar 2,43% pada 3500 rpm, 1,67% pada 4500 rpm, dan 1,08% pada 7000 rpm. Hasil penelitian menunjukkan bahwa penambahan oil cooler mampu menurunkan suhu oli mesin secara signifikan. Dengan suhu yang lebih stabil, risiko keausan komponen mesin dapat diminimalisir dan performa mesin tetap optimal. Kesimpulannya, oil cooler efektif digunakan sebagai sistem pendinginan tambahan pada sepeda motor 4 langkah 115 cc. High engine temperatures on motorcycles greatly affect the performance and lifespan of components, especially pistons and cylinder walls. A less than optimal oil cooling system can cause oil temperatures to increase and risk overheating. This study aims to analyze the effect of adding an oil cooler on engine temperature on a 4-stroke 115 cc motorcycle. The method used is an experiment by comparing the engine temperature before and after the installation of the oil cooler. Measurements were made under the same operational conditions to determine the effectiveness of the oil cooler in reducing engine temperature at each rotation level. The percentage of temperature reduction was recorded at 2.43% at 3500 rpm, 1.67% at 4500 rpm, and 1.08% at 7000 rpm. The results showed that the addition of an oil cooler was able to significantly reduce the engine oil temperature. With a more stable temperature, the risk of engine component wear can be minimized and engine performance remains optimal. In conclusion, the oil cooler is effectively used as an additional cooling system on a 4-stroke 115 cc motorcycle.

Abstract

Pregnancy is a reproductive process that requires special attention so that it runs smoothly because it involves the lives of the mother and fetus (Elisabeth, 2020). Prenatal yoga is one way to prepare mothers physically and psychologically, including reducing anxiety before giving birth. Prenatal Yoga helps expectant mothers prepare themselves to face childbirth with confidence, happiness, comfort, without fear, as well as strengthening and forming body posture. The aim of this service is to increase the knowledge and participation of pregnant women in carrying out prenatal yoga exercises to improve health and reduce discomfort during pregnancy. The steps for this activity consist of establishing relationships, submitting proposals and setting schedules, as well as involving an evaluation process with a question and answer session. This counseling includes lecture methods, discussions, practices, and audio-visual media during prenatal yoga. The result of this community service activity is that 60% of pregnant women had poor knowledge about prenatal yoga before receiving counseling. After being provided with information about prenatal yoga, the knowledge of pregnant women increased by about 90%. The recommendation from the community service group to pregnant women is to improve their health by practicing prenatal yoga, including body movements and breathing techniques that can provide a relaxing effect, help reduce physical stress, and facilitate the delivery process.

Abstract

Fenomena saturasi pada trafo arus memiliki dampak krusial terhadap kinerja rele proteksi dalam sistem tenaga listrik. Pengujian eksperimental dilakukan untuk menganalisis karakteristik trafo arus, dengan fokus pada hubungan antara arus masukan primer (I1​), arus keluaran sekunder (I2​), dan tegangan keluaran (V). Hasil menunjukkan korelasi positif antara I1​ dengan I2​ dan V. nilai V tetap konstan pada 5,5 Volt meskipun I1​ meningkat dari 600 mA ke 800 mA, dan nilai I yang kembali ke 1,3 A pada tegangan tertentu dalam pengujian terpisah. potensi saturasi inti trafo atau perilaku non-linear komponen yang diuji, yang berpotensi memengaruhi akurasi pengukuran arus oleh rele proteksi. khususnya saat mendekati atau memasuki kondisi saturasi. Perilaku non-linear, seperti yang ditunjukkan oleh nilai V yang stabil pada dua titik I1​ yang berbeda, dan penurunan I pada tegangan yang meningkat, pengujian karakteristik trafo arus secara menyeluruh untuk memastikan rele proteksi dapat beroperasi secara akurat dan tepat waktu, terutama dalam menghadapi kondisi gangguan yang mungkin menyebabkan saturasi trafo.   The saturation phenomenon in current transformers has a crucial impact on the performance of protection relays in electric power systems. Experimental testing was conducted to analyze the characteristics of current transformers, focusing on the relationship between primary input current (I1), secondary output current (I2), and output voltage (V). The results showed a positive correlation between I1 and I2 and V. The V value remained constant at 5.5 Volts even though I1 increased from 600 mA to 800 mA, and the I value returned to 1.3 A at a certain voltage in a separate test. potential saturation of the transformer core or non-linear behavior of the components under test, which could potentially affect the accuracy of current measurement by the protection relay. especially when approaching or entering saturation conditions. Non-linear behavior, as indicated by stable V values at two different points of I1, and a decrease in I at increasing voltage, thorough testing of the current transformer characteristics to ensure the protection relay can operate accurately and timely, especially in the face of fault conditions that might cause transformer saturation.

Abstract

This study presents a thermo-structural finite element analysis of a single-cylinder diesel piston using ANSYS, comparing three aluminum alloys: Al2618-T61, Al4032-T6, and Al6061-T6. A coupled simulation approach was applied, where steady-state thermal results were imported into static structural analysis. Realistic boundary conditions, including applied combustion pressure, symmetry constraints, and cylindrical pin supports, were implemented based on Yanmar TF55 engine geometry. Results indicate that Al6061-T6 experienced the highest deformation and stress, nearing its yield limit at elevated temperatures. In contrast, Al2618-T61 and Al4032-T6 maintained structural integrity, with lower stress and elastic deformation within safe limits. Al4032 demonstrated superior dimensional stability, while Al2618 exhibited better strength under thermal load. These findings validate the importance of coupled thermal-structural analysis and material selection in piston design. The proposed framework offers reliable guidance for developing more durable, thermally resilient pistons for modern diesel engines.

Abstract

This research investigates the impact of Continuously Variable Transmission (CVT) roller weight on fuel consumption and engine performance in motorcycles. The study involved experimental testing of motorcycles fitted with rollers of varying weights (9 grams and 12 grams) to evaluate their effects on fuel consumption, and overall engine performance. This study concludes that the choice of CVT roller weight significantly affects both fuel consumption and engine performance, with potential implications for optimizing motorcycle efficiency based on user preferences and riding conditions. This study found that the 9-gram roller produced greater torque and power (7.85 Nm at 3,500 RPM, 8.45 hp at 6,500 RPM) than the 12-gram roller, but its fuel consumption was higher at low RPM (SFC 0.07 kg/hp.h at 1,500 RPM).

Abstract

This study critically examines the effectiveness of mortgage right execution under Indonesian civil procedural law in addressing non-performing loans. Employing a normative juridical approach through literature review, it analyzes statutory provisions and legal doctrines, particularly Law No. 4 of 1996 on Mortgage Rights. The findings reveal that despite the availability of mechanisms such as parate executie, executorial titles, and private sales, practical implementation remains hindered by complex bureaucracy, debtor objections, and procedural inefficiencies. The study highlights the potential role of digitalization, particularly blockchain technology, in enhancing transparency and legal certainty. It recommends regulatory harmonization, development of digital infrastructure, and a rights-based legal framework to strengthen protection for creditors, debtors, and third parties.
