Construction project control requires careful planning to avoid delays and cost overruns. This study aims to evaluate the performance of the CBT Laboratory Building construction project at the Faculty of Medicine, Wahid Hasyim University, Semarang, in terms of cost and time using the Earned Value Analysis (EVA) method, and to analyze acceleration alternatives using the crashing method. The method used is a quantitative approach with a case study, based on project data such as the Budget Plan (RAB), S-curve, and work progress reports. The analysis was carried out using the Earned Value Analysis (EVA) method to assess project performance in terms of cost and time through indicators such as CV, SV, CPI, and SPI. Furthermore, an acceleration analysis was conducted using the crashing method to determine the optimal alternative for overcoming project delays by considering time and cost efficiency. The results of the Earned Value Analysis indicate that the project experienced delays and cost overruns, as shown by SPI < 1 and CPI < 1. The estimated project completion time increased to 227 days, longer than the initial plan of 217 days, while the estimated final cost reached RP 5,451,241,064.85, exceeding the initial budget. Acceleration efforts using the crashing method show that adding adding labor is more efficient than working hours (overtime), resulting in a project duration of 212 days with lower costs of RP 5,658,221,364.08. Thus, the Earned Value Analysis method is effective for evaluating project performance, while crashing can be a solution for acceleration by considering time and cost efficiency.

Dredger operations in water-based mining areas have a high occupational risk because they involve a combination of wet environments, mechanical equipment, and electrical systems. The presence of electrical panels, power cables, terminal connections, electric motors, inverters/drives, and protection components on the Dredger requires a sound understanding of Occupational Health and Safety, particularly electrical safety. Water splashes, wet walking surfaces, high humidity, and improper procedures during inspection or cleaning may increase the risk of short circuits, protection trips, and electric shock. Therefore, structured basic safety training is required so that operators are able to identify electrical hazards and implement safe working procedures. This activity aimed to improve operators’ understanding of hazardous electrical components, initial safety briefing procedures, measurement practice and safe handling during trips or short-circuit indications, and the correct and safe use of water pumps for unit cleaning. The activity was carried out through field observation, technical briefing, direct demonstration on the electrical panel and work area, simple measurement practice, and safe cleaning practice. The results indicate that field documentation can serve as an effective learning medium to strengthen operators’ understanding of electrical hazard sources on the Dredger, the application of simple lock out-tag out procedures, the control of wet areas, and the limitation of water spray direction during cleaning activities. Overall, the activity shows that improved compliance with safety procedures may reduce the risk of short circuits and electric shock during operation and maintenance.

Background: Acne vulgaris is one of the most common skin problems and is closely associated with the activity of Propionibacterium acnes. Long-term use of antibiotics may lead to bacterial resistance; therefore, alternative antibacterial agents derived from natural products are needed. White rice (Oryza sativa L.) is known to contain bioactive compounds such as flavonoids, alkaloids, terpenoids, tannins, and saponins, which potentially exhibit antibacterial activity. Objective: This study aimed to evaluate the antibacterial activity of ethanol extract of white rice against the growth of Propionibacterium acnes. Methods: This research was conducted as a laboratory experimental study using a post-test only control group design. The ethanol extract of white rice was prepared by maceration using 70% ethanol. Antibacterial activity was evaluated using the disc diffusion method with extract concentrations of 100%, 50%, 25%, 12.5%, and 6.25%. Clindamycin was used as a positive control, while sterile distilled water served as a negative control. The parameter observed was the diameter of the inhibition zone. Result: The results of phytochemical screening showed that the ethanol extract of white rice (Oryza sativa L.) contains flavonoids, alkaloids, and terpenoids. Antibacterial activity test showed that the ethanol extract of white rice at concentrations of 100%, 50%, and 25% was able to inhibit the growth of Propionibacterium acnes by forming an inhibition zone, while at concentrations of 12.5% and 6.25% no inhibition zone was formed. The highest inhibition zone diameter was found at a concentration of 100%. The ethanol extract of white rice at concentrations of 100% (7.65 mm), 50% (6.77 mm), and 25% (6.15 mm) was able to inhibit the growth of Propionibacterium acnes, and was classified as having moderate inhibition. In contrast, at concentrations of 12.5% and 6.25%, the ethanol extract of white rice did not show any inhibitory activity detected in vitro using the disc diffusion method. The results of statistical analysis showed a p value <0.001, which means there was a significant difference in the diameter of the inhibition zone between the treatment groups. Conclusion: In conclusion, the ethanol extract of white rice exhibits antibacterial activity against Propionibacterium acnes in a concentration-dependent manner; however, its inhibitory effect remains lower than that of clindamycin.

The consistent decline in cucumber production in Indonesia indicates limitations in conventional cultivation systems, particularly due to land scarcity and inefficient resource management. This condition has encouraged the development of hydroponic systems as a more controlled and productive cultivation alternative. This study aims to critically analyze the key factors determining the success of hydroponic cucumber cultivation and to identify the most influential management aspects in improving yield. The method employed is a literature review, examining various recent studies related to hydroponic systems, nutrient management, growing media, and environmental factors. The results show that the advantages of hydroponics lie not only in land and water efficiency but also in the ability to precisely control growth variables. However, optimal productivity highly depends on the proper integration of nutrient management, particularly the regulation of pH, electrical conductivity (EC), and nutrient balance, as well as the control of environmental factors such as temperature, humidity, and light intensity. Inaccuracy in a single component can significantly reduce plant performance, even when other factors are optimal. Therefore, an integrated approach combining nutrient and environmental management simultaneously is essential to enhance hydroponic cucumber productivity. This study confirms that hydroponics has strong potential as a strategic solution to support sustainable agriculture amid land limitations in Indonesia.

The quality of rice that is suitable for consumption, one of which is determined by the absence of associated components when the rice is in storage. Rice storage is carried out by means of long shelf life and good rice quality. Damage to rice due to pest attacks causes a decrease in quality and quantity. Environmentally friendly efforts are needed to control the rice weevil Sitophilus oryzae using vegetable materials. This study sought to ascertain the death rate of rice weevils treated with lemongrass stem (Cymbopogon citratus), bay leaves (Syzygium polyanthum), and pandan leaves (Pandanus amaryllifolius). The study employed a fully randomized design with three treatments in the form of simplicia plant components. There were 21 study units because each treatment included seven repetitions. Each treatment used 20 rice weevil imago breeding results which were infested in a jar containing 200 g of rice for 4 weeks in the laboratory. The use of pandan leaf, bay leaf, and lemongrass simplicia at 7 days after treatment showed the proportion of rice weevil mortality was 59,29%, 39,29%, and 50,00%, respectively. As for the observations of 14 day after treatments, 21 day after treatments, and 28 day after treatments showed that the mortality rate of all rice beetles was above 50%. Regarding the percentage of rice powder, hollow rice, and rice weight loss, the findings of observations on rice weevil mortality did not reveal any significant variations across all treatments.

Postharvest handling of leafy vegetables, such as kale (Brassica oleracea var. acephala), is crucial for maintaining product quality and market value. This study aims to review the application of sorting and grading processes in improving the quality of horticultural products. The method used is a literature review of scientific journals and relevant references related to postharvest handling of vegetables. The findings indicate that sorting functions to separate damaged and unmarketable products based on physical condition, while grading classifies products into quality categories based on size, shape, and visual appearance. These processes contribute to reducing postharvest losses, improving product uniformity, and increasing market value. Furthermore, proper sorting and grading support quality control and enhance efficiency in distribution and marketing systems. Therefore, sorting and grading are essential components of postharvest management to ensure product quality and market competitiveness.

This model offers a digital resilience approach that can be replicated in other educational institutions with similar characteristics.

This study aims to analyze legal protection for auction winners of mortgage rights within the framework of Indonesian laws and regulations. The auction of mortgage rights serves as a mechanism for executing secured collateral with binding legal force; however, in practice, it often raises legal issues, particularly concerning legal certainty and protection for auction winners. This research employs a normative juridical method using statutory and conceptual approaches. The findings indicate that legal protection for auction winners has been regulated under various laws, including the Mortgage Law, auction regulations, and provisions governing collateral execution. Nevertheless, challenges remain in its implementation, such as lawsuits filed by debtors or third parties that hinder the transfer and control of auctioned objects. This condition reflects a discrepancy between legal norms and their practical application. Therefore, strengthening regulations and ensuring consistency among law enforcement authorities are necessary to guarantee legal certainty and protection for auction winners. This study is expected to contribute to the development of secured transactions law and the improvement of auction practices in Indonesia.

Hypertension is one of the most common chronic diseases encountered in primary healthcare and may lead to serious complications if left uncontrolled. This case report aims to describe the management of a 48-year-old female patient with grade II hypertension through a family medicine approach at Nisam Primary Health Center, North Aceh Regency. The patient presented with intermittent headaches for one week, which worsened after physical activity and were accompanied by numbness in both legs. She had a five-year history of hypertension with poor adherence to antihypertensive medication. Physical examination revealed a blood pressure of 165/70 mmHg, leading to a diagnosis of grade II hypertension. Comprehensive management was conducted using patient-centered and family-centered approaches, including education regarding hypertension, lifestyle modification, DASH diet implementation, physical activity, medication adherence, and family support through home visits and family folders. The interventions were expected to improve blood pressure control, prevent complications, and enhance the patient’s quality of life. A family medicine approach plays an important role in comprehensive hypertension management at the primary healthcare level.

This study aims to analyze a comparison of coal stockpile volumes using the DJI Mavic 3 Pro Unmanned Aerial Vehicle (UAV) method versus the truck count method at PT. Mitra Barito. Data collection was conducted through aerial photography using a UAV at altitudes of 60 meters and 70 meters, as well as Ground Control Point (GCP) measurements using GPS. The aerial imagery data was processed using photogrammetry software to generate orthophotos and a Digital Elevation Model (DEM), followed by a geometric accuracy test based on the Geospatial Information Agency Regulation No. 6 of 2018, using the Circular Error 90% (CE90) and Linear Error 90% (LE90) parameters. The research results show that high-quality processing at an altitude of 60 meters yields a CE90 value of 2.1619 meters and an LE90 value of 4.3656 meters, thereby meeting the accuracy standards for RBI maps at a scale of 1:5,000, Class 3 for horizontal accuracy, and a scale of 1:10,000, Class 3 for vertical accuracy. Volume calculations of the stockpile using UAVs yielded a result of 22,750.900 m³, while the truck count method produced a volume of 23,503.300 m³. The volume difference between the two methods was 753.400 m³, with a deviation percentage of 3.2%. Based on the research results, the UAV method is considered capable of providing relatively accurate calculations of coal stockpile volume.

This study examines land-use transformation in Hamadi Rawa I, Jayapura City, focusing on the shift from water catchment to built-up land during 2015–2025. The research employs a mixed-methods approach, combining analysis of Google Earth imagery with interviews with community, government, and academic stakeholders. Findings show the catchment area shrank by 48% (from 17% to 8% of the total area), decreasing from 21.36 ha to 11.20 ha. The built-up area increased by 28.1%, from 70.78 ha to 90.67 ha, with residential development driving most of this growth (51.1%). Three spatial transformation patterns emerged: ecological fragmentation, linear service sector development, and concentric settlement patterns. Idle land was also identified as a phenomenon that damages ecological functions without providing a productive benefit. The conversion was driven by physical-natural factors (basin topography), economic factors (market proximity), socio-demographic factors (urbanization), and especially institutional factors. Customary land transactions outside state control created a governance dilemma between humanity and public order. The study recommends a proactive-collaborative approach with three key instruments: (1) Zero-Reclamation with Adaptive Permitting for stilt structures; (2) fiscal intervention using Idle Land Tax and Payment for Ecosystem Services; and (3) a Participatory Spatial Control Task Force integrating government and customary authorities (Ondoafi).

According to the Regulation of the Minister of ATR/BPN of the Republic of Indonesia No. 14 of 2022 concerning the Provision and Utilization of Green Open Space, an area must have at least 30% Green Open Space of its total area with details of 20% as Public Green Open Space and 10% as Private Green Open Space. The availability of Public Green Open Space in Pangkalpinang City is ± 1,486 ha or ± 14% of the total area, less than 6% of the applicable provisions. The purpose of writing this scientific article is to determine the potential distribution of Public Green Open Space in Pangkalpinang City as an effort to fulfill the availability of Green Open Space in the area. The variables or data used are open land by considering residential / non-residential areas, building density, distance from roads and distance from rivers, as well as land ownership or control status, content in the Spatial Plan, and Green Open Space typology. This study uses overlay analysis techniques to determine the distribution of potential Public Green Open Space in the Pangkalpinang Region. The results of the study indicate that there is still a distribution of potential land that can be developed into public green open space including green open space areas/zones in the form of road borders and other areas/zones in the form of areas that provide protection to the area below, spring borders, underpasses, beaches, and rivers. The distribution of potential public green open space can be used as a consideration in fulfilling the availability of public green open space in the Pangkalpinang area of ​​20% of its area. The fulfillment of Public Green Open Space can provide ecological and social functions for the surrounding environment.

Given the important objectives that banks strive to achieve through financial stability and their role in ensuring its continuity and ability to face various economic challenges, many have expanded their policies beyond their traditional functions by adopting a range of additional practices and activities that contribute to strengthening their developmental role in society. Among the most prominent of these practices are corporate social responsibility (CSR) activities, which have become a crucial aspect of the work of contemporary financial institutions. In this context, this research highlights CSR practices in banks. It relied on a sample of nine Iraqi banks listed on the Iraq Stock Exchange, which are characterized by their continued banking operations and regular publication of their annual financial reports. The research period was set from 2014 to 2023, and included a set of statistical tests that incorporated a number of financial determinants as control variables to determine their contribution to enhancing the impact of CSR when included alongside it, and to define the nature of the relationship between the research variables. We have reached a number of conclusions, most notably that when regulatory variables are included in the analysis model, this effect becomes statistically insignificant, which indicates that banks’ interest in internal financial factors still outweighs their interest in social aspects.

This study aims to gain an in-depth understanding of the legal reasoning used by judges in the Administrative Court (PTUN) in annulling State Administrative Decisions (KTUN), as well as to examine the legal implications for the parties involved and the overall system of government administration. This research employs a normative juridical method with three approaches: statutory, conceptual, and case approaches. The analysis was conducted qualitatively by studying reference books and reviewing court decisions. The study shows that the annulment of KTUN by PTUN judges is based on three important factors, namely lack of authority (ultra vires), procedural defects, and substantive defects in the decision. In addition, violations of the General Principles of Good Governance (AUPB), such as the principles of legal certainty, prudence, and proportionality, also constitute important considerations for judges. In the judicial process, judges not only consider the formal aspects of the law, but also take into account substantive justice in order to protect citizens’ rights from improper governmental actions. The implications of the annulment of KTUN include the restoration of the plaintiff’s rights through the process of restitutio in integrum, the obligation of administrative officials to revoke or correct the issued decision, as well as the potential impact on third parties involved in the decision. In general, the annulment of KTUN serves as a legal control mechanism over government administration while also encouraging the realization of good and transparent governance within a state governed by the rule of law.

This study aims to determine the effect of the deep learning learning approach on fourth-grade elementary school students’ understanding of IPAS concepts, particularly on the topic of pollination in perfect flowers. This research employed a quantitative approach with a quasi-experimental design using a pre-test and post-test control group design. The population consisted of all fourth-grade students of SDN 4 Muara Dua, totaling 58 students, who were divided into experimental and control classes through total sampling techniques. Data collection techniques included tests, observations, and documentation. The research instruments were tested for validity and reliability before being implemented in the study. The results revealed that the implementation of the deep learning approach had a positive effect on students’ understanding of IPAS concepts. This was indicated by the higher post-test scores achieved by students in the experimental class compared to those in the control class. In addition to improving conceptual understanding, the deep learning approach also enhanced students’ critical thinking skills, activeness, and participation during the learning process. Therefore, the deep learning learning approach can be considered an effective alternative strategy to improve elementary school students’ understanding of IPAS concepts.

Rebonding is a chemical hair straightening procedure widely popular in Indonesia, involving two-stage redox reactions on keratin disulfide bonds using ammonium thioglycolate and hydrogen peroxide. Although it provides effective hair-straightening results, rebonding potentially causes significant damage to the hair cuticle structure. This study aimed to analyze the morphological changes of hair surface before and after rebonding treatment through a descriptive comparative case study approach using Scanning Electron Microscopy (SEM). The samples consisted of one strand of healthy, chemically untreated hair (control) and one strand of post-rebonding hair that both obtained from a female. Samples were prepared using gold-sputter coating prior to SEM observation. Representative SEM images from each sample were then qualitatively compared based on cuticle morphology parameters. The results showed clear morphological differences between the two samples: the control hair displayed tightly arranged and orderly cuticle scales with a smooth surface, while the post-rebonding hair showed surface erosion and the presence of cracks in multiple areas of the cuticle. These findings confirm that rebonding procedures cause visible and characterizable morphological cuticle damage as identified through SEM, providing a scientific basis for developing more protective post-rebonding hair care products.

The quick advancement of digital technology has drastically changed the social and religious life of Indonesian teenagers. The purpose of this study is to investigate how pupils at Al Muslim Junior High School's daily worship practices, self-control, and fear of missing out (FoMO) affect the principles of Islamic Religious Education (PAI). The study used a quantitative methodology with a causal and correlational design. All students in grades VII, VIII, and IX made up the study population for the 2025–2026 school year. Using the Slovin formula, a proportionate stratified sample of 171 students with a 5% margin of error was chosen. A five-point Likert scale questionnaire was used to gather data. The Pearson Product-Moment correlation (r > 0.30) was used to evaluate validity, while Cronbach's Alpha (α > 0.70) was used to test reliability. Multiple linear regression using SPSS version 26 was used for quantitative analysis, beginning with traditional assumption tests for heteroscedasticity (Glejser), multicollinearity (VIF), and normality (Kolmogorov-Smirnov). According to the analysis results, self-control had a substantial, favorable impact on the practice of PAI values, but FoMO had no significant influence (β = -0.034, p = 0.530).

The pollution of the Ciliwung River caused by urban and commercial activities has become an increasingly critical environmental issue, reflecting the weak effectiveness of environmental law enforcement in urban areas. This condition is evident in the area surrounding Seasons City Mall, where ecological pressure resulting from domestic waste and commercial activities has contributed to the deterioration of river water quality. This study aims to analyze the implementation of environmental law enforcement, identify the obstacles to controlling pollution in the Ciliwung River, and formulate strategies for optimizing sustainable environmental protection. The research employs a qualitative approach using normative juridical and empirical methods through observation, interviews, documentation, and literature review. The findings reveal that environmental law enforcement has been implemented through administrative supervision and waste control mechanisms; however, its effectiveness remains limited due to weak inter-agency coordination, inadequate monitoring capacity, low compliance among business actors, and limited public participation. This study concludes that strengthening integrated supervision, enforcing consistent legal sanctions, and enhancing collaboration among government institutions, business sectors, and communities are essential to achieving sustainable pollution control and environmental protection of the Ciliwung River.
