Abstract

Background: Dyslipidemia is an abnormal condition (increase or decrease) in cholesterol lipoproteins, including an increase in total cholesterol, triglycerides, and low-density lipoprotein (LDL) levels, as well as a decrease in high-density lipoprotein (HDL) levels. Metabolism plays a role in converting nutrients into compounds necessary for life processes, such as energy sources (ATP). Research Objective: To determine the effect of administering single garlic extract (Allium sativum var solo garlic) on weight gain in male Rattus winstar rats with dyslipidemia. Research Methods: This quasi-experimental study used 24 male Wistar rats, single garlic extract, butter, quail eggs, used cooking oil, and scales. The study population consisted of 24 male Wistar rats, which were divided into four groups of six rats each using Federer's formula. The treatments in this study were: the positive group was given standard feed and simvastatin; the negative group was given standard feed and aquabides; treatment group 1 was given 200 mg/kgBW of single garlic extract; and treatment group 2 was given 400 mg/kgBW of single garlic extract. Body weight assessments were conducted four times, namely on days 7, 14, 21, and 28. The research data analyzed were total cholesterol, LDL count, HDL count, triglyceride count, and body weight. Data were analyzed for normality using the Shapiro-Wilk test, and if normally distributed, continued with a one-way parametric ANOVA test and Tukey HSD post-hoc test. Data were analyzed using IBM SPSS 23 for Windows, with P values < 0.05 interpreted as statistically significant. Research Results: The mean values and standard deviations for the positive group were 234±13.20 on day 7, 223±12.29 on day 14, 231.83±11.99 on day 21, and 227.5±10.15 on day 28. Negative group on day 7 (237.33±18.52), day 14 (240±7.84), day 21 (238.5±17.28) and day 28 (239.16±9.62). Treatment 1 on day 7 (261.5±27.22), day 14 (296±21.63), day 21 (316.33±21.05) and day 28 (334.16±17.03). Treatment 2 on day 7 (290±10.62), day 14 (327.16±7.41), day 21 (344.33±45.39) and day 28 (385.83±13.43). Administration of 400 mg/kgBW single garlic extract significantly (P = 0.02 < 0.05) increased the body weight of rats compared to the positive and negative control groups. Conclusion: Based on the results of this study, single garlic extract in test animals showed an increase in body weight in dyslipidemic rats, indicating the need for further research on the mechanism of weight gain due to the administration of single garlic extract.

Abstract

Fuel efficiency is a critical indicator in ship operations and maritime education, particularly within the context of sustainability. This study addresses the issue of increasing fuel consumption and exhaust gas emissions caused by suboptimal engine maintenance practices. The objective of this research is to analyze the impact of routine maintenance on the fuel efficiency of the main engine aboard the training vessel KL. Sultan Hasanuddin 02. A quasi-experimental method was employed, involving field observations, technical measurements using a flowmeter and gas analyzer, and interviews with the Chief Engineer. Data were collected before and after the implementation of maintenance procedures based on the Planning Maintenance System (PMS). The results showed a 12.5% improvement in fuel efficiency, along with reductions in CO₂ emissions by 16.4%, NOx by 19.2%, and SOx by 18.8%. These findings demonstrate that routine maintenance not only enhances energy efficiency but also mitigates the environmental impact of the ship's propulsion system. Key supporting factors include technician competence, operational conditions of the vessel, and the quality of fuel used. This research provides both practical and academic contributions to the development of data-driven main engine maintenance guidelines, which are relevant to vocational maritime education and efforts to improve energy efficiency in the shipping sector.

Abstract

This study aimed to examine the effect of the Premature Infant Oral Motor Intervention (PIOMI) on feeding skills in premature infants at RSUD Koja Jakarta, given that feeding skill dysfunction (mean gestational age 34.03 weeks) often leads to delayed oral feeding and prolonged hospitalization. Utilizing a one-group pretest-posttest quasi-experimental design, 30 premature infants were recruited via purposive sampling. The PIOMI intervention was administered intensively for 6 consecutive days, twice daily, starting at a mean chronological age of 6.8 days. Feeding skills were measured using the Early Feeding Skills Assessment Tool (EFSAT) before and after the intervention, and data were analyzed using the Paired Sample t-Test. Results showed that the mean EFS score significantly increased from 31.37 (pretest) to 47.17 (posttest), yielding a mean improvement of 15.8 points. The hypothesis test produced p < 0.001, indicating a highly significant effect of PIOMI. Furthermore, Cohen's d = 8.560 indicated a very strong, clinically relevant effect size (Very Large Effect). Functionally, 20% of subjects transitioned fully from OGT to oral feeding, and 43.3% increased their oral volume, accompanied by a mean weight gain from 1974.83 gr to 2049.23 gr. It is concluded that PIOMI is highly effective and has a strong clinical impact on improving feeding skills in premature infants, and its implementation as a standard protocol in the NICU is recommended to accelerate feeding independence.

Abstract

Occupational Safety and Health (OSH) is a fundamental aspect in creating a safe working environment, especially in high-risk laboratories such as road laboratories. Although the use of this laboratory is quite intensive for practical activities and research at the University of Lampung, to date there has been no comprehensive study on the extent to which OSH is effectively implemented. Therefore, this study aims to evaluate the implementation of OSH in the Road Laboratory of the University of Lampung with reference to national regulations. This study uses a qualitative descriptive approach with the location at the Road Laboratory of the Faculty of Engineering, University of Lampung. The research population includes students, lecturers, and laboratory staff, while the sample is determined purposively. Data collection techniques were carried out through observation, semi-structured interviews, questionnaires, and analysis of SOP documents and safety reports. The data were analyzed descriptively through categorization, interpretation, and comparison with Permenaker No. 5 of 2018 and ISO 45001:2018. The results of the study indicate that although most OSH facilities, such as PPE and SOPs, are available, the level of user compliance still varies and waste management is not yet optimal. The conclusion of this study is that there is a need to increase socialization, supervision, and strengthen the OSH management system so that laboratories can function safely, effectively, and efficiently.

Abstract

The 7 Kebiasaan Anak Indonesia Hebat program is one of the priority program of the Ministry of Primary and Secondary Education of the Republic of Indonesia. It aims to develop students with strong academic ability, good behavior, and strong character. The program is implemented in all primary and secondary schools, and thus large amounts of data must be summarized for monthly reports. Urban schools often use Google Forms or digital applications to record students’ activities, while schools in smaller towns or rural areas still rely on paper forms. Limited access to smartphones and internet connections among parents makes online data collection difficult. Consequently, teachers must manually summarize data using spreadsheet applications, increasing their workload—especially when managing many students. This study proposes the use of Canny Edge Detection to automate data processing from OMR (Optical Mark Recognition) sheets. By scanning or photographing filled OMR sheets, the system can accurately read and convert students’ responses into digital data. This method allows teachers to digitize the reporting process and reduce manual work. Using this method, the accuracy of reading the OMR sheets can reach 81% while the need of informing the parents to fill the form correctly since some tested data shown recall data reached 68%.

Abstract

This study aims to analyze and balance the production line in the assembly process using two Line Balancing methods, namely Helgeson–Birnie (H-B) and the Largest Candidate Rule (LCR), with a cycle time (CT) set at 2.28 minutes (137 seconds) based on the manual bottleneck workstation. The total element work time was recorded at 19.39 minutes, with a minimum required number of 9 workstations. The calculation results from both methods showed consistent and identical solutions, yielding 10 actual workstations (N_actual = 10). The line performance achieved a Line Efficiency (LE) of 85.04% with a Balance Delay (BD) of 14.96%. Although this efficiency is considered good, idle time analysis revealed a total waste of 3.41 minutes, most of which occurred at Workstation 10, which operated for only 0.20 minutes. These findings indicate that improvements should focus on restructuring the final workstation to eliminate waste, increase LE, and streamline total element time to approach the Takt Time, thereby optimizing overall line performance. This study provides practical recommendations for production management to enhance productivity and the efficiency of the assembly line.

Abstract

 This study aims to analyze the role of agricultural technology in improving food crop productivity and its impact on national food security and public health in Indonesia. A literature review approach was employed by examining relevant national and international scientific publications related to agricultural mechanization, precision agriculture, superior crop varieties, and modern irrigation systems. The findings indicate that the application of agricultural technology significantly improves farming efficiency, reduces post-harvest losses, and increases both the quantity and quality of food crop production. Increased productivity plays an important role in strengthening national food security through enhanced food availability, stability, and accessibility. Moreover, improved access to sufficient and nutritious food contributes to better nutritional status and overall public health outcomes. Despite these positive impacts, the adoption of agricultural technology in Indonesia still encounters several challenges, including limited access for smallholder farmers, unequal regional implementation, inadequate human resource capacity, and insufficient policy and financial support. These constraints may hinder the optimal utilization of technology and limit its broader benefits for food security and public health. Therefore, integrated policies and strong cross-sector collaboration between agriculture, health, and development sectors are essential to ensure that increased food productivity effectively translates into improved community welfare and sustainable development.

Abstract

Sustainable watershed management requires decision-making frameworks that are both scientifically robust and socially legitimate. This study develops an integrative management model for the Alo-Molamahu Sub-Watershed, part of the Limboto Watershed in Gorontalo Province, Indonesia, by combining hydrological modeling, spatial analysis, and social–institutional assessment within an epistemological framework. A mixed-methods design was employed, integrating biophysical data derived from Geographic Information Systems (GIS) and the Soil and Water Assessment Tool (SWAT) with qualitative data obtained from interviews, questionnaires, and policy document analysis. Model calibration and validation using observed discharge data from River Flow Monitoring Stations demonstrate strong agreement between simulated and observed hydrological responses. The results indicate that land-use change on steep slopes and limited vegetation cover significantly increase runoff and sediment yield, while socio-economic pressures and weak policy instruments constrain effective conservation practices. Through systematic data triangulation, biophysical model outputs were interpreted alongside stakeholder perceptions and regulatory conditions to generate an evidence-based and adaptive watershed governance model. The study demonstrates that integrating validated hydrological simulations with social knowledge enhances both the scientific credibility and policy relevance of watershed management strategies. The proposed framework provides a replicable approach for sustainable management of complex socio-ecological watersheds in Indonesia and comparable contexts.
