Arif Rakhman — 2025-05-21

The inventory information system currently employed by the General Administration Department remains largely manual, relying on Microsoft Office Excel. This approach results in inefficiencies, particularly in the retrieval and processing of inventory data, which tends to be slow and prone to errors. In response to these limitations, this study aims to develop a more efficient, user-friendly inventory management system that improves access to information and streamlines data and file handling. The proposed system is designed to enhance operational efficiency within administrative units, particularly the logistics sub-division, by providing accurate records of goods management activities, including procurement, inventory, and transactional processes. With the implementation of this system, it is expected that the handling of university logistics data will become faster, more reliable, and less prone to human error. Moreover, access to logistical information will be more readily available whenever required, supporting timely and informed decision-making.

Strategies for Managing Renovation Project Delays: An Integrated Approach to Project Communication and Stakeholder Engagement Using the Critical Path Method.

Indra Karmawan — 2025-05-22

Delays in hotel renovation projects can significantly disrupt business continuity, increase operational costs, and erode stakeholder confidence. This study investigates the primary causes of delay and the role of stakeholder influence in managing renovation projects, focusing on the Hotel X Jakarta renovation case. A mixed-method approach was adopted, combining quantitative analysis through questionnaires and Exploratory Factor Analysis (EFA), along with qualitative insights from stakeholder interviews. Fifty respondents representing both internal and external actors were selected from a total of 100 identified project stakeholders.

The findings revealed three dominant causes of delay: (1) ineffective communication and coordination among project teams, (2) decision-making delays by internal managerial staff, and (3) lack of involvement of key stakeholders in the early phases of the project. The most influential contributors to delay were internal decision-makers, government regulators responsible for permitting, and external consultants who failed to deliver project documentation on time. Stakeholder mapping showed that these actors possessed both high power and high interest, yet their engagement was either misaligned or delayed.

These results indicate that project delays are not only technical issues but are also deeply rooted in behavioral, organizational, and structural dynamics. To mitigate such delays, renovation projects should integrate stakeholder engagement strategies with proactive communication planning and scheduling tools such as the Critical Path Method (CPM). This integrated approach provides a more resilient framework for managing complexity in multi-stakeholder renovation environments.

Lukmanul Khakim — 2025-05-31

A septic tank is a temporary storage place for household waste, in which there are several gases that if the concentration increases, it will cause several impacts on the health and safety of people or the community around the septic tank. Previous research related to monitoring and neutralizing gas sewers in septic tanks has been successfully made, but the tool has shortcomings in terms of the use of the HC-SR04 sensor, where if the sensor is in humid conditions for a long time, then its performance cannot be optimal, due to the influence of humid space, therefore it is necessary to optimize the tool in terms of detecting the level of fulfillment of septic tank volume. As a result of optimizing the septic tank volume detection sensor which was replaced with the JSN-SR04T sensor, the volume detection results are more accurate and more stable, this is because the JSN sensor is waterproof, so that intervention from a humid environment is minimized. Testing from the two sensors found that the accuracy level of HC-SR04 in measuring distances between 20 to 200 cm, with 12 tests, the accuracy level of JSN-SR04T was 100%, and HC-SR04 was 90.1%.

Suryaneta Suryaneta — 2025-05-31

This study aimed to develop and validate a service quality measurement instrument specifically for brick-and-mortar cosmetic retail stores in Lampung Province, Indonesia. An initial pool of 40 items—reflecting six dimensions (store aesthetics, ambience, lighting, product display, store layout, and staff service quality)—was generated based on the literature and refined through expert review and pilot testing. Data were collected from 126 customers of three major cosmetic retailers in Lampung. Exploratory factor analysis (EFA) on 33 retained items revealed a stable three-factor structure (“Store Aesthetics,” “Ambience & Lighting,” and “Product Display, Layout & Staff Service”), explaining 70.6% of the total variance. Confirmatory factor analysis (CFA) confirmed model fit (CFI = 0.96; TLI = 0.95; RMSEA = 0.045; SRMR = 0.042). Each factor demonstrated high internal consistency (α ≥ 0.878; CR ≥ 0.90) and acceptable convergent validity (AVE ≥ 0.56) and discriminant validity. The final 26-item scale offers a psychometrically sound tool for assessing service quality in Indonesian cosmetic retail environments. Practically, managers can use this instrument to identify areas for improvement—in interior design, sensory ambience, merchandise presentation, store layout, and staff training—to enhance customer satisfaction and loyalty.

Analysis of Trends and Correlation Between Ground-based PM₂․₅ and Satellite AOD in Jakarta (Dec 2022–Mar 2025)

Marthin Abednego Gultom — 2025-05-31

Monitoring of PM₂․₅ concentrations in urban areas such as Jakarta is crucial given its impact on public health (WHO, 2021) and the urban environment (Zhang et al., 2020), where measuring PM₂․₅ levels is essential for assessing air quality and health risks in metropolitan regions, including Jakarta. However, the limited number of ground-based monitoring stations and variable weather conditions often result in uneven PM₂․₅ data availability (Alim et al., 2023). As an alternative, satellite-derived Aerosol Optical Depth (AOD) can serve as a proxy for particulate pollution monitoring (Liang et al., 2018).This study aims to analyze the temporal trends and quantify the correlation between ground-based PM₂․₅ and satellite AOD in Jakarta from December 2022 through March 2025. PM₂․₅ data were obtained from five Air Quality Monitoring Stations (SPKU) located in Kebon Jeruk, Bundaran HI, Kelapa Gading, Lubang Buaya, and Jagakarsa, while AOD was extracted via Google Earth Engine (MODIS MCD19A2) at the same five locations. Key methods include additive seasonal decomposition of each time series, calculation of Pearson and Spearman correlation coefficients, and cross-correlation analysis to determine the optimal lag. The results indicate that both PM₂․₅ and AOD trends rose from mid-2023, peaked in early 2024, and then gradually declined through late 2024; monthly correlations were very strong (Pearson r = 0.71, p < 0.001; Spearman ρ = 0.76, p < 0.001). Seasonal analysis revealed concentration maxima during the dry season (June–September) and minima in the wet season (December–February). Cross-correlation shows that AOD leads PM₂․₅ fluctuations by one month (lag +1). These findings underscore the potential of satellite AOD as a monthly proxy for estimating PM₂․₅ in Jakarta, supporting more spatially and temporally comprehensive air quality monitoring than ground-based networks alone. In conclusion, satellite AOD can be used as a supplementary indicator for PM₂․₅ air quality monitoring in Jakarta, particularly to fill gaps in ground-based PM₂․₅ data coverage.
