Abstract

Human resource operations in many Indonesian companies still rely heavily on manual systems, leading to inefficiencies, data inaccuracies, and delays. This study examines the development and implementation of an Android and cloud-based Human Resource Information System (HRIS) at PT Sari Ater, a hospitality company facing such operational challenges. The objective is to reduce processing time, improve data accuracy, and enhance employee satisfaction by digitizing core HR functions such as leave requests, reimbursement claims, attendance tracking, and training records. The study adopts a qualitative descriptive method, including interviews, observations, and document analysis, and applies the Trees Rapid Track Cloud Implementation Methodology. A four-week pilot involving 35 employees showed significant improvements: leave approval times dropped from over 4 days to under 1 day, reimbursement processing was reduced by 65%, and form entry errors declined by over 80%. Employee satisfaction with HR services also increased substantially. These findings demonstrate that integrating mobile and cloud technologies can transform HR operations in SMEs, increase transparency, and support digital transformation. The system offers a scalable model for similar organizations seeking to modernize their HR management and foster a culture of accountability and efficiency.

Abstract

This research aims to analyze the distribution cost structure and transportation requirements for CPO-FAME-Biodiesel to meet B40 quota implementation in Java Island using a dynamic system approach. This study uses dynamic system simulation with Vensim software to model CPO-FAME-Biodiesel distribution from Sumatra and Kalimantan to Java Island, utilizing data from Ministry of Energy and Mineral Resources and GAPKI with 2025 projections. The simulation reveals that meeting the B40 quota in Java Island requires substantial infrastructure investment with total transportation costs exceeding IDR 1.3 trillion, highlighting the massive scale and logistical complexity of national biodiesel implementation. Analysis identifies fleet tariff, shipping frequency, fleet capacity, raw material prices, and conversion ratios as the primary cost drivers affecting distribution efficiency. Cost optimization can be achieved through strategic shipping frequency management, capacity optimization, efficient fleet fuel management, and implementation of centralized production systems with hub-and-spoke distribution networks. This research contributes essential strategic insights for policymakers in developing cost-effective transportation frameworks and infrastructure planning for Indonesia's national biodiesel policy implementation.

Abstract

The objective is to examine the extent to which Islamic values, such as honesty (sidiq), responsibility (amanah), consistency (istiqamah), wisdom (fathanah), and effective communication (tabligh) are internalized in daily work routines and how they contribute to performance outcomes. A quantitative descriptive-correlational method was applied, involving 57 Muslim midwives working in the Bougenville Unit at RSUD Dr. Soedirman Kebumen. Data were collected using validated structured questionnaires, and analysis was conducted using simple linear regression via SPSS 25. The results revealed that Islamic work culture was implemented at a good level (mean score: 76.7%), and midwife productivity was also rated good (mean score: 75.8%). Regression analysis demonstrated a significant positive relationship (p = 0.02), with Islamic work culture explaining 13.7% of productivity variance (R² = 0.137). These findings highlight the practical implication that integrating Islamic values into human resource policies can enhance work performance and foster ethical professionalism. Institutions with strong religious backgrounds may benefit from aligning their organizational culture with spiritual values to improve service quality and employee well-being.

Abstract

This study evaluates the effectiveness of Distribution Requirements Planning (DRP) integrated with ARIMA time series forecasting to support delivery scheduling decisions and the determination of minimum inventory levels. As a representative case study, a 60-month sales series of Ultra-Pure Water was used to simulate fluctuating retail demand across the agent–depot network. The Augmented Dickey–Fuller test confirmed stationarity (p = 0.0142), allowing candidate ARIMA (p, 0, q) models to be evaluated using ACF/PACF and information criteria. The best model was ARIMA (1,0,1), which had the lowest Akaike Information Criterion and passed diagnostic tests (normal residuals, no autocorrelation, no heteroscedasticity), making it suitable for operational forecasting. Projection results indicated a stable demand pattern and yielded a safety stock threshold of 733.24 units/month (equivalent to 24.44 units/day) as a reference for inventory control. These findings demonstrate that the DRP–ARIMA integration can enhance supply reliability and distribution efficiency, particularly for subsidized goods such as 3 kg LPG, with practical implications for determining adaptive inventory levels, delivery routes and frequency, and upstream–downstream coordination. Theoretically, this study provides additional empirical evidence on the use of quantitative forecasting models to operationalize DRP in the energy sector, while also providing a foundation for replication in other critical commodities.

Abstract

The rapid growth of manufacturing demands continuous process improvement. This study examines a plastic manufacturing company’s Mouldshop, which has not met performance targets an average lead time of 52 days (target 50 days) and a 75% success rate (target 93%) and struggles to achieve the desired surface finish quality of plastic molds. An integrated Value Stream Mapping (VSM) and Six Sigma DMAIC approach is applied to visualize end-to-end process flows (VA/NNVA/NVA), quantify performance gaps, analyze root causes (Fishbone with the 4M Man, Machine, Material, Method), and design improvements. VSM reveals three dominant wastes defects, inappropriate processing, and waiting linked to six critical failure causes spanning operator capability and discipline; overloaded schedules, equipment failures, machining errors, temperature control, and precision instability; material selection and procurement delays; and shortcomings in work- instruction compliance, machining parameters, drawing completeness, and standardized process flow. Using 5W+1H within DMAIC, the study proposes: standardized machining instructions and setup times; preventive- maintenance schedules and checklists; incoming verification with PIC accountability; structured training; mold quality checklists; weekly 5S/5R audits; and Future State Mapping to reduce NNVA/NVA. The integrated DMAIC–VSM roadmap is expected to shorten lead time, raise the value-added ratio, and improve surface finish quality, offering a transferable blueprint for similar manufacturing operations.
