Accurate evaluation of head losses is essential in industrial systems transporting viscous chemical fluids, such as sodium hydroxide (NaOH), to ensure hydraulic efficiency and operational reliability, particularly in chlor alkali plants. This study analyses major and minor flow losses in the NaOH piping system at PT X Chlor Alkali Plant, Porsea, and evaluates the pipe design's hydraulic feasibility. After defining system parameters—including fluid properties, pipe geometry, and the number and type of fittings—technical calculations were conducted to assess flow profiles and pressure losses along two main pipe routes. A quantitative analysis using the Moody diagram and operational data reveals that minor losses dominate, contributing over 75% of total head loss in both routes. The total head loss remains within the pump's rated capacity (18 m), though with a narrow margin. A pipe diameter of 0.114 m produces a flow velocity of 0.79 m/s, aligning with recommended industrial standards for corrosive fluids. The use of Sch.80 stainless steel proves effective in minimizing frictional losses, particularly under turbulent flow conditions. These findings highlight the critical role of fitting configurations and material selection in optimizing chemical process piping systems.

Work fatigue is a physical condition that weakens workers, causing less than optimal work capacity and endurance. Lactic acid is produced from anaerobic metabolism or carbohydrate metabolism without oxygen. This happens because there is not enough oxygen to support muscle energy production. The body that cannot produce the amount of lactic acid that is comparable to the rate of its synthesis, then the muscle pH will decrease, this is what inhibits glycolysis enzymes resulting in physical fatigue. Physical fatigue is the effect of increased levels of lactic acid in the body, especially muscles. One of the jobs at PT. X in Kampar Regency that can cause work fatigue is a palm oil harvester. This study is an observational study type with a cross-sectional study design. Data were obtained using interviews using a BMI questionnaire. Data collection was also carried out to obtain BMI measurement data, pulse measurements, blood pressure measurements, and lactic acid measurements with Accutrend Plus Roche Brand on 138 harvesters at PT. X Kampar Regency. In this study, the independent variable is the level of lactic acid and the dependent variable is work fatigue. The results of the study showed that the harvesters who experienced moderate work fatigue were 13 people (11.4%). The harvesters who experienced high work fatigue were 54 people (47.4%). The harvesters who experienced very high work fatigue were 47 people (41.2%). The high proportion of workers who experienced high and very high work fatigue (88.6%) reflects the significant physical workload that must be faced by oil palm harvesters at PT. X. Harvesters with lactic acid levels <2 mmol/l (not increasing) were 13 people (11.4%) and harvesters with lactic acid levels> 2 mmol/l (increasing/hyperlactatemia) were 101 people (88.6%). From the results obtained, a significant increase in lactic acid levels in 88.6% of respondents indicated that most workers experienced higher muscle fatigue conditions during work with increased lactic acid levels.

This study examines the impact of bureaucratic reform through merit system implementation on political elite behavior and patronage politics practices in regional government. Using a mixed-method approach combining quantitative analysis of 150 regional governments and qualitative case studies in five provinces during 2019-2024, this research investigates how civil service recruitment reforms influence transactional political practices. The study employs New Public Management theory, political patronage theory, and institutional change theory to analyze the transformation of elite behavior. Results indicate that merit system implementation significantly reduces political patronage practices (β = -0.627, p < 0.001), with stronger effects in regions with higher institutional capacity and civil society oversight. However, political elites adapt by shifting patronage mechanisms from recruitment to procurement and project allocation. The study reveals that successful bureaucratic reform requires simultaneous strengthening of transparency mechanisms, political accountability, and civil society participation. These findings contribute to understanding the complex relationship between administrative reform and political behavior change in decentralized governance systems.
