This research is to test a theoretical model about the impact of the organizational climate as a result of servant leadership and conflict management towards organizational citizenship behavior with as mediator; the organizational commitment of PT Pegadaican (Pesero). The total number of respondents was 213 consisting of employees of the Central Office, the Jakarta I Area Office and the Jakarta II Area Office. To collect the data, the instrument utilized was a Linkert Technique scale questionnaire, after which the data was processed using a Lisrel 8.72 software version deploying applicative statistics using The Sructural Equation Model (SEM), and for analysis Confimatory Factor Analys Confimatory and Factor Analys technique was used. As the result it could be concluded that the hypothesis of the research is in accordance with the theoretical model about the impact of servant leadership, and conflict management on organizational citizenship behavior with as mediator the organizational commitment of the PT. Pegadaian (Pesero); the data did support this accordance and could be accepted. The same was the case for the structural equation hypotheses, and in general it could be concluded that the organizational climate created by servant leadership had a direct, positive and significant impact on organizational citizen behavior, and that conflict management had an direct positive but insignificant impact on organizational citizenship behavior. Furthermore, the organizational climate, servant leadership and conflict management had direct and positive impact on organizational commitment and the organizational climate, servant leadership and conflict management had an indirect, positive and significant impact on organizational citizenship behavior through the mediator of organizational commitment.

A turbine is a drive that converts potential energy into kinetic energy and kinetic energy. The nature of magnets with the same poles will result in a repulsive force or a pushing force. The aim of this research is to determine the effect of magnet diameter and magnet attack angle and their interaction on the tangential force in a magnetic turbine using neodymium permanent magnets. The research method used is experimental on a magnetic turbine using neodymium permanent magnets. Variations in the diameter of the magnet are 15 mm, 20 mm, 25 mm, and 30 mm and variations in the angle of attack of the magnet are 5°, 10°, 15°, 20°. The results obtained in this research are that in the clockwise rotation direction the optimal tangential force value is 4.648 N with a magnet diameter of 30 mm and an angle of attack of 5°, while in the counterclockwise rotation direction the optimal tangential force value is 4.087 N with a diameter 30 mm magnet and angle of attack 5°.

Penelitian ini bertujuan untuk mengetahui pengaruh arah serat dan fraksi volume serat terhadap kekuatan impak komposit berbasis serat karbon untuk aplikasi helm. Spesimen dibuat menggunakan metode vacuum infusion dengan kombinasi serat karbon dan resin epoxy infusion. Pengujian impak dilakukan menggunakan metode Charpy dengan variasi arah serat (0°, 30°, 60°, dan 90°) serta dua tingkat fraksi volume serat (31% dan 46%). Hasil menunjukkan bahwa arah serat merupakan faktor yang paling berpengaruh terhadap kekuatan impak. Spesimen dengan arah serat 0°, yaitu sejajar dengan arah beban tumbukan, menghasilkan kekuatan impak tertinggi. Semakin besar penyimpangan sudut dari 0°, kekuatan impaknya menurun secara signifikan. Peningkatan fraksi volume dari 31% menjadi 46% juga meningkatkan kekuatan impak, namun pengaruhnya tidak sebesar arah serat. Nilai kekuatan impak tertinggi sebesar 0,2459 J/mm² diperoleh pada spesimen dengan fraksi volume 46% dan arah serat 0°, jauh melebihi standar minimum helm SNI sebesar 0,00972 J/mm². Temuan ini menunjukkan bahwa penyusunan serat sejajar dengan arah beban serta peningkatan fraksi volume serat merupakan faktor penting dalam menghasilkan helm komposit yang kuat, ringan, dan memenuhi standar keselamatan.

Proses penghalusan media dengan permukaan kasar secara manual sering kali kurang efektif, baik dari segi waktu maupun hasil yang presisi, akibat kecepatan putaran motor yang tidak terkendali. Untuk mengatasi hal ini, dikembangkan alat penghalus permukaan bidang kasar dengan sistem kontrol PI untuk pengaturan kecepatan motor AC 1 fasa. Sistem ini menggunakan Arduino UNO sebagai pengendali sudut motor servo, yang mengatur driver melalui potensiometer berdasarkan nilai setpoint dan sensor optocoupler sebagai pembaca kecepatan motor. Berdasarkan pengujian dengan menggunakan media yang dihaluskan berupa bonggol jagung untuk mewakili bidang dengan permukaan kasar, kontrol PI dengan parameter Kp = 0,405 dan Ki = 0,1215, mampu menghasilkan error steady state maksimal sebesar 3,14% dan minimal 0,14% pada setpoint kecepatan putaran motor sebesar 1400 RPM. Sistem ini terbukti meningkatkan stabilitas kecepatan dan efisiensi waktu dalam proses penghalusan bidang dengan permukaan kasar.

Jamu kunyit asam merupakan minuman herbal tradisional yang kualitasnya dipengaruhi oleh ketepatan takaran kunyit dan kestabilan suhu perebusan. Pada produksi manual, variasi jenis kunyit dan suhu yang tidak terkontrol menyebabkan warna serta rasa jamu kurang konsisten. Penelitian ini mengembangkan sistem otomasi terintegrasi yang mencakup penakaran kunyit berbasis koreksi warna hasil rebusan dan kontrol suhu perebusan menggunakan metode PID. Sensor load cell digunakan untuk mengukur berat kunyit, sedangkan kamera Pixy2 mendeteksi warna berdasarkan nilai RGB. Hasil pengujian koreksi warna kuning muda dengan target 200 g menunjukkan berat terbaca 198,8–202,1 g dengan eror 0,6–1,05%, sedangkan koreksi warna kuning dengan target 100 g menghasilkan berat terbaca 99,9–103,3 g dengan eror 0,1–3,3%. Aktivasi LED pada Pixy2 terbukti meningkatkan akurasi klasifikasi warna dengan mengurangi variasi RGB yang tidak terstandarisasi. Pada proses perebusan, sensor DS18B20 digunakan sebagai input kontrol PID untuk mengatur valve gas melalui motor servo sehingga suhu stabil pada 85–90°C. Hasil tuning PID dengan parameter Kp = 33.28, Ki = 0.27, dan Kd = 10 memberikan overshoot 0,44%, rise time 39 menit, dan eror steady-state 0.06%.

This study aims to analyze the application of the Average Effective Rate (TER) in calculating Article 21 Income Tax (PPh) for employees with a Fixed-Term Employment Agreement (PKWT) pattern at the security outsourcing service company PT TFN. The application of TER is compared with the progressive rate of Article 17, especially after the enactment of the Minister of Finance Regulation (PMK) Number 168 of 2023 concerning Guidelines for the Implementation of Tax Withholdings on Income in Connection with Work, Services, or Activities of Individuals. The study uses a qualitative approach with triangulation techniques through in-depth interviews, field observations, and document analysis, including simulations of PPh 21 calculations using the progressive method and TER for PKWT employees for the period January–December 2024 with various dependent statuses (TK/0, K/0, K/1, K/2, K/3). The results show that TER simplifies the calculation and reporting of PPh 21 and increases administrative efficiency by around 40–50 percent compared to the progressive rate. However, from a fiscal perspective, TER tends to result in potential underpayments of around 30–40 percent on annual tax returns, especially for employees with variable incomes and multiple dependents (K/2 and K/3). This finding confirms the trade-off between administrative efficiency and tax fairness and suggests that the principle of vertical fairness has not been fully achieved. The study recommends increasing TER socialization, tax education for PKWT employees, and strengthening the integration of digital tax systems to minimize the risk of underpayments and future tax disputes.
