Abstract

This study analyzes the influence of constructin value variation on project control effectiveness in Indonesia using a quantity explanatory research design. The data were obtained from the statistics Indonesia (BPS) 2023 report, specifically the dataset on constructin categories. Descriptive analysis reveals highly extreme value variations with several large-scale outliers. Pearson correlation analysis indicates very strong relationship (≥ 0,97) among value categories, suggesting simulatneous escalatin in multi component projects. The findings imply that higher construction values requier more complex control mechanism, including Earned Value Management (EVM), structured risk mitigation, and strist change-order management. This study recommends adopting value-based project control classifications to enhance the effectiveness of cost anda schedule oversight and to support optimal construction project performance.

Abstract

This study aims to identify the most suitable country of origin for Indonesia’s machinery imports by analyzing import data from 2018 to 2024 using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. Secondary data obtained from the Central Bureau of Statistics (BPS) include import volume, CIF value, logistics costs, trade stability, and import growth. The analysis process consists of constructing the decision matrix, normalizing the data, assigning criterion weights, determining ideal solutions, and calculating preference values for each alternative country. The results indicate that China is the most optimal source of machinery imports, achieving the highest preference score due to its dominance in volume, economic value, supply consistency, and trade growth. South Korea and the “Others” category follow as strategic alternatives. Overall, the TOPSIS method proves effective in providing objective and measurable support for multi-criteria decision-making related to selecting import partner countries.

Abstract

This study maps development priorities for rail freight in Indonesia based on the spatial distribution of freight volume by major island groups. A descriptive quantitative approach was applied using secondary data on rail freight volume (thousand tons) across five island groups. The analysis includes volume tabulation, share calculations, Java-to-other regions dominance ratios, and a Java versus non-Java aggregate comparison. Results indicate a total of 33.0 million tons, dominated by Java at 18.5 million tons (56.06%), followed by Sumatra 7.2 (21.82%), Kalimantan 4.1 (12.42%), Sulawesi 2.3 (6.97%), and Bali–Nusa Tenggara 0.9 (2.73%). The dominance ratio of Java reaches 20.56 over Bali–Nusa Tenggara and 8.04 over Sulawesi, while non-Java accounts for 43.94% (14.5 million tons). These findings support prioritizing rail freight development outside Java through strengthened logistics nodes and intermodal integration.

Abstract

This study aims to optimize the inventory control of plastic pellet raw materials in the production line of PT. Tiplas by applying mathematical models consisting of Economic Order Quantity (EOQ), Safety Stock, Reorder Point (ROP), and Total Inventory Cost (TIC). One year of observation shows that raw material usage fluctuates significantly, with notable differences in monthly consumption. Such conditions require the company to implement a more structured and measurable inventory control system to ensure smooth production activities and minimize the risk of stockouts. Analysis of monthly consumption data indicates that the average daily demand reaches 768 units, with a standard deviation of 329.24 units, reflecting a high level of demand uncertainty. Using a probabilistic inventory approach, the study determines the optimal order quantity at 9,601 units, safety stock at 1,880 units, and a reorder point at 11,099 units. The results demonstrate that the applied model provides more efficient inventory control recommendations, reduces total inventory costs, and ensures better readiness of raw material availability to support continuous production operations.

Abstract

The environmental challenge faced by communities living in residential areas is the issue of plastic waste. Many households do not yet understand the classification of waste types and lack the habit of waste segregation. Consequently, this leads to an accumulation of plastic waste. This community service activity, conducted in RT 13, Bumi Candi Asri Housing, Sidoarjo, aims to initiate a culture of plastic waste segregation at the household level to support the creation of a clean and sustainable environment. The methods employed include education on plastic types and direct assistance in plastic sorting. The results indicate a significant increase in community awareness, with 90% of residents now separating plastic waste into saleable categories. This initiative has successfully reduced the volume of plastic waste sent to landfills (TPA) and has also emerged as a new economic source for the residential environment. This activity is expected to strengthen awareness of healthy living behaviors and realize a sustainable environment. .

Abstract

This study aims to determine the optimal allocation of planting areas for rice (X₁) and corn (X₂) in order to maximize agricultural profit in East Java Province. The agricultural sector in this region faces significant limitations in key resources, particularly land, fertilizer, and labor, which necessitate efficient and quantitatively grounded management strategies. This study employs a Linear Programming approach using the graphical method, based on a mathematical model developed from simulated data representing regional agricultural conditions. The results indicate that the optimal land allocation consists of 60 hectares for rice and 40 hectares for corn, generating a maximum profit of IDR 1,300,000,000. The constraint analysis reveals that land and fertilizer constraints act as binding constraints at the optimal solution, while the labor constraint is non-binding. This finding implies that further profit improvements cannot be achieved by increasing labor input, but rather by expanding or optimizing land use and fertilizer availability. Overall, this study provides a clear analytical framework to support decision-makers in formulating more efficient land allocation policies and improving agricultural productivity through optimal resource utilization

Abstract

Network security in hospital environments represents a critical challenge due to high traffic volumes and the sensitivity of medical data. This study aims to evaluate the performance of a Snort-based Intrusion Detection System (IDS) in detecting network attacks within the Mitra Keluarga Hospital infrastructure. The evaluation was conducted using an experimental approach by deploying Snort on a monitored server segment and performing simulated attacks, including port scanning, SSH brute force, ICMP flooding, and SQL injection. System performance was assessed based on detection respone time, detection rate, and alert consistency. The results demonstrate that the IDS successfully detected all tested attack scenarios, achieving respone times ranging from 0.4 to 1 second and a detection rate of 100% under the experimental conditions. However, potential false positives were identified in internal ICMP traffic, indicating the need for threshold parameter adjustment. These findings indicate that a Snort-based IDS is effective as an early attack detection mechanism for hospital networks and can be further enhanced through integration with centralized monitoring systems to support informed network security decision-making

Abstract

This study develops an optimized inventory control policy for pipe products characterized by intermittent demand in a manufacturing company in Surabaya. Monthly demand data from January to December 2024 were analyzed using the Average Demand Interval (ADI) and the Coefficient of Variation Squared (CV²) to classify demand behavior. The results indicate an ADI of 2.6 and a CV² of 0.82, confirming a lumpy intermittent demand pattern. Based on this classification, inventory parameters were determined for a 15-day lead time. The proposed policy yields a safety stock of 18 units and a reorder point of 25 units at a 95% service level. Implementation of the integrated forecasting–inventory approach reduces annual inventory costs by 21.7% and improves material availability from 89% to 95%. Findings demonstrate that demand classification-based inventory decisions provide measurable operational and economic improvements for project-oriented manufacturing environments.

Abstract

This study aims to measure the process efficiency of student admission (PPDB) using a work measurement approach by comparing manual and digital systems at a private vocational school in Surabaya. A quantitative–comparative design was applied to ten complete admission process records, evaluating three indicators: process time, administrative error rate, and staff workload. Data were collected through structured time study, error logging, and daily task records during one admission period. The results indicate that the digital system reduces process time by 50–90%, decreases the error rate from 15% to 5%, and improves staff productivity by minimizing overtime. The three indicators were integrated into a composite efficiency index adapted from Overall Equipment Effectiveness (OEE), yielding 18.7% for the manual system and 80.7% for the digital system. These findings confirm that digitalization significantly enhances service process performance and provides a measurable industrial engineering framework for improving administrative efficiency.

Abstract

The use of small-scale solar energy is one of the strategic solutions for electricity needs in remote areas and outdoor activities. As the need for portable electrification increases, the development of solar backpack systems is becoming a practical and sustainable alternative. This research aims to design and test a portable backpack system based on a thin film solar panel with a capacity of 20 Wp, equipped with a 12V solar charge controller and a 7.2 Ah battery. The system is designed with two outputs, namely 12V DC and 5V USB, to support lightweight devices such as LED lights and smartphones. The test was carried out at two different locations, namely Mount Lorokan and Mount Penanggungan, with data taken which included latitude, longitude, solar elevation angle, PV voltage, PV current, and output power. The measurement results show that there is a variation in the performance of solar panels according to geographical conditions and solar elevation angles. On Mount Lorokan, the peak power reaches 8.55 W at an angle of 75°, while on Mount Penanggungan the maximum power is slightly higher, which is 8.6 W at an angle of 78°. Mount Lorokan excels at maximum power, Penanggungan shows more stable performance at low to medium angles. This research contributes to the development of a portable electrification system based on renewable energy that supports power continuity in locations without access to electricity.
