Abstract

Hospital wastewater has characteristics that distinguish it from wastewater generated by other human activities. The purpose of this study is to analyze and evaluate the operation of Hospital Wastewater Treatment Plants in West Surabaya and assess how well they affect the quality of the wastewater they produce. The research method applied is direct observation of the WWTP process and discussion with the person in charge of the hospital's WWTP in West Surabaya. The evaluation results show that some WWTP process units are operating according to standards, but some process sections show a decrease in efficiency, which impacts the quality of the water produced. The average removal rate for the parameters BOD5 was 95.03%, COD was 93.73%, NH3-N was 99.9%, and PO4 was 96%. These results indicate that all parameters meet the applicable quality standards and optimization of the maintenance of the WWTP system is required.

Abstract

Logistics processes, particularly in the loading and unloading area, pose a critical challenge for the Bottled Drinking Water (AMDK) industry, as they have the potential to reduce profitability due to waste. This study aims to eliminate non-productive activities in the distribution line of PT XYZ using a Lean Manufacturing approach. By integrating Value Stream Mapping (VSM) to map process flows and the Waste Assessment Model (WAM) to weight operational issues, this study examines the company’s operational problems. The identification results indicate that defect is the most dominant form of waste, contributing 24.37% of the total waste variability, which significantly hampers distribution flow. Root Cause Analysis (RCA) highlights employee discipline and operational work instructions as the primary factors causing these defects. As a mitigation strategy, this study formulates improvement recommendations based on restructuring work instructions and strengthening employee discipline standards to reduce defect rates and accelerate service lead time.

Abstract

Air quality is an important aspect in maintaining environmental sustainability in industrial work areas. In facilities that rely on backup power systems such as generator sets, emission release remains a potential source of air pollution, particularly during operation. This study investigates ambient air quality, noise levels, and models the potential dispersion of genset emissions at PT. X. Ambient air, emission, and noise measurements were conducted directly in the field. The results showed that all ambient air quality and noise parameters were below the applicable regulatory limits, with differences influenced by surrounding activities, location characteristics, and genset operation schedules. Dispersion modeling using AERMOD indicated that the highest pollutant concentrations occurred near the emission source and decreased with distance, influenced by wind direction and speed. The modeling results suggest that the environmental impact of genset emissions remains low and within acceptable limits.

Abstract

The handling of Hazardous and Toxic (B3) waste needs a storage system that satisfies technical criteria in an effort to reduce environmental damage and health hazards. This study aims to evaluate the level of compliance of the Temporary Sotrage Area (TPS) for B3 waste at PT. X with the applicable technical requirements. The research was conducted through field observations, measurement of technical parameters, and examination of licensing documents and B3 waste management records. The results indicate that the compliance level of the B3 waste TPS reached 95.88%, and falls into the highest performance category. Several issues were still identified, particularly in the aspects of B3 waste accumulation and the provision of symbols and labels. Therefore, this study recommends the implementation of periodic internal audits and improved compliance with B3 waste packaging and labeling standards.

Abstract

The objective of this research was to identify the most dominant waste, calculate the average cycle time per unit at each work station, and provide suggestions for improving the production process. The approach used was Lean Manufacturing with the tools of Value Stream Mapping (VSM) and Waste Assessment Model (WAM). VSM was used to map the process flow and identify non-value-added activities, while WAM was used to assess the dominance of waste using the Waste Relationship Matrix (WRM) and Waste Assessment Questionnaire (WAQ). The analysis results showed that defects were the most significant waste, contributing 14.57%. The main causes were inconsistencies in boiling temperatures and printing errors. In addition, imbalances in cycle times between work stations were found. Proposed improvements focused on the Future State VSM, in the form of process standardization, temperature control, and rearrangement of work areas. The implementation of this method is expected to improve production efficiency sustainably.

Abstract

This study is motivated by high transportation costs caused by direct material distribution from suppliers in Bandung to four project sites without passing through a central distribution warehouse. The distribution distances reach 152 km (C1), 154 km (C2), 139 km (C3), and 143 km (C4), resulting in increased logistics costs, difficulties in inventory control, and project completion delays. Consequently, the target of installing 100 utility poles per site within 20 days was not achieved, leading to a decline in project KPI performance. This study aims to determine the optimal distribution warehouse location using the Center of Gravity (COG) and Analytical Hierarchy Process (AHP) methods. The research adopts a descriptive approach with mixed methods. Data were obtained from company documents for cost information and from interviews and discussions to collect distance and distribution volume data, as well as to validate criteria and alternative locations. The COG analysis produced coordinates X = −6.702795806 and Y = 108.5351786; however, this point is located in an alley area and is therefore unsuitable as a warehouse site.

Abstract

Hydrocarbon reserve estimation is a fundamental aspect in oil and gas field development planning and project economic evaluation. This study compares two reserve estimation approaches: reservoir simulation using Computer Modelling Group (CMG) and Decline Curve Analysis (DCA) with Microsoft Excel. CMG simulation uses IMEX module to model conventional reservoir with Original Oil in Place (OOIP) of 1.9735 × 10⁷ STB. DCA method analyzes three production decline models with initial production rate parameter of 1,065 BOPD and decline rate of 50% per year. Results show different 36-month cumulative production predictions: Exponential decline yields 172 MBO, Hyperbolic decline 212 MBO, and Harmonic decline 241 MBO with difference reaching 40%. Hyperbolic decline method provides optimal balance for heterogeneous reservoir characteristics. Combination of both approaches provides strong cross-validation for more accurate reserve estimation in supporting field development decision making.

Abstract

Limited agricultural land and increasing demand for food have encouraged the implementation of efficient and sustainable production systems. Biocyclofarming-based hydroponic systems are an alternative because they optimise the use of water, nutrients and biological waste in a closed cycle. This study aims to analyse the application of Closed-Loop Supply Chain (CLSC) in a water spinach hydroponic system in Balongsari Village. The study was conducted through supply chain flow mapping, crop productivity analysis, calculation of total supply chain cost structure, and evaluation of biological waste return flow as production input. The research object included local-scale water spinach hydroponic production units. The results showed that the application of CLSC was able to effectively integrate forward and reverse flows, increase resource use efficiency, and reduce system waste. Economically, the identified cost structure supported fair pricing and the sustainability of hydroponic businesses.
