Distribusi energi listrik dari pusat pembangkit listrik (power plant) ke jaringan beban tambang yang letaknya berjauhan selalu mengalami terjadiya rugi-rugi (losses), salah satunya adalah rugi tegangan. Rugi tegangan akan menyebabkan terjadinya jatuh tegangan (drop voltage) yang cukup besar, yang mengakibatkan rendahnya tegangan terima terutama yang berada di ujung saluran jaringan tegangan menengah (JTM). Drop Voltage pada saluran tenaga listrik secara umum berbanding terbalik dengan luas penampang penghantar. Sehingga penambahan luas penampang penghantar akan sangat berpengaruh terhadap perbaikan jatuh tegangan.Metode untuk memperbaiki jatuh tegangan pada sistem distribusi jaringan tegangan menengah (JTM) 20 kV di suatu feeder diantaranya adalah rekonduktor penghantar yaitu dengan mengganti luas penampang menjadi lebih besar dan mengganti jenis penampang konduktor. Penelitian ini menganalisis penambahan luas penampang penghantar terhadap drop voltage. Perhitungannya dilakukan dengan cara memasukan data-data yang didapat dari katalog spesifikasi kabel serta sebagai pembanding dilakukan pengukuran nilai resistansi dan induktansi pada kabel AL 3 x 240 mm dan CU 3 x 70 mm dengan mengambil sampel langsung dilapangan.Penelitian dilakukan pada penghantar jenis kabel AAAC (All Alumunium Alloy Conductor) 3 x 240 mm², dan kabel CU 3 x 70 mm. Hasil simulasi perhitungan menunjukkan nilai drop voltage nya 1,11% untuk kabel tembaga, 0,83% untuk kabel Alumunium. Dengan dilakukannya rekonduktor penghantar dengan penambahan luas penampang penghantar akan menurunkan drop voltage, sehingga dapat meningkatkan kualitas serta keandalan sistem tenaga listrik.

Cardiac disease is one of the major causes of death in the world. Early diagnose of the symptoms depends on abnormality on heart beat pattern, known as Arrhythmia. A novel fuzzy neuro generalized learning vector quantization for automatic Arrhythmia heart beat classification is proposed. The algorithm is an extension from the GLVQ algorithm that employs a fuzzy logic concept as the discriminant function in order to develop a robust algorithm and improve the classification performance. The algorithm is tested against MIT-BIH arrhythmia database to measure the performance. Based on the experiment result, FN-GLVQ is able to increase the accuracy of GLVQ by a soft margin. As we intend to build a device with automated Arrhythmia detection, FN-GLVQ is then implemented into Field Gate Programmable Array to prototype the system into a real device.

Electromigration is a critical issue in materials science and electrical engineering, significantly impacting the reliability and efficiency of electrical systems. This study investigates the electromigration behavior of PVC-insulated copper wires under various overcurrent conditions, focusing on material degradation and electrical performance. Copper cables, identified as 046620.3 Eterna CU/PVC 1.5 mm2, were subjected to currents ranging from 0 to 110 A. The mean time to failure (MTTF) was calculated using Black’s equation, revealing a sharp decline in MTTF with increasing current density. Surface morphology analysis using SEM showed the formation of voids and hillocks at higher currents, indicating severe electromigration damage. XRF analysis demonstrated significant changes in the elemental composition, particularly a reduction in copper content and an increase in chlorine and other elements, suggesting degradation of the PVC insulation. FTIR spectroscopy revealed substantial chemical changes in the PVC material, especially under extreme overcurrent conditions, highlighting dehydrochlorination and carbonyl group formation. There is a clear relationship between overcurrent conditions and electromigration phenomena, as evidenced by the observed damage to surface morphology, changes in elemental composition, and alterations in the chemical structure of PVC. The mechanisms and causes of electromigration are explained comprehensively in this work, illustrating how increased overcurrent accelerates the electromigration process, leading to the formation of voids and hillocks in the copper conductor. This damage is accompanied by a significant reduction in copper content and an increase in chlorine levels, indicating the degradation of PVC insulation. FTIR spectra further confirmed these findings by showing chemical changes such as dehydrochlorination and carbonyl group formation under high current stress. The MTTF values reflect the severity of these impacts, with samples exposed to higher currents showing drastically reduced lifespans. For instance, samples subjected to 100 A and 110 A currents exhibited MTTF values of 0.2 minutes and 0.004 minutes, respectively.

The low learning outcomes of fifth-grade students at SDN 173265 Onan Hasang were attributed to a lack of interest in learning, stemming from ineffective teaching methods that were not suitable for the subject matter. This research aimed to enhance students' abilities, learning outcomes, and activities in social studies (IPS), particularly in the topic of Indonesia's natural phenomena. A classroom action research (CAR) method was employed, targeting specific samples. The findings demonstrated the following: 1) Improvement in Learning Outcomes: The contextual teaching model effectively increased students' academic performance in social studies. 2) Content Relevance: Emphasis on local contexts, such as Indonesia's natural phenomena, engaged students by connecting the material to their environment. 3) Active Student Participation: The contextual learning model encouraged active involvement in the learning process. 4) Enhanced Critical Thinking Skills: Students showed improved critical and analytical thinking abilities through this approach. 5)Future Implications: The contextual teaching model presents an effective alternative for enhancing social studies education, particularly in understanding local environmental phenomena.

Warehouses have an important role for companies, including PT. XYZ located in Karawang. This research aims to optimize truck queues in the loading and loading process at PT. XYZ uses a discrete simulation approach with ProModel software. The problem of long truck queues and high delivery order (DO) waiting times disrupted the operational efficiency of distribution facilities. In this study, 3 simulation scenarios were tested to evaluate the impact of adding loading docks on throughput, waiting time, and resource usage by removing the Delivery Order (DO) waiting time. The data collected includes loading and loading process time, namely truck arrival data, warehouse information data, transport truck information data, and product information data implemented using ProModel software and then validated through replication tests and validity tests using the t-test method. The simulation results show that using scenario 1, the addition of one loading dock increases throughput by 45% and reduces the average wait time from 18 minutes to 9.3 minutes per truck. In addition, the use of resources becomes more optimal, increasing overall productivity. With these results, the study concludes that the addition of loading dock is an effective solution to overcome bottlenecks in the loading process at PT. XYZ, which can be implemented to improve operational efficiency.
