The growth of the nickel mining industry in Indonesia, particularly in Southeast Sulawesi Province, has made this sector one of the main contributors to the Regional Gross Domestic Product (RGDP). However, the development of supporting infrastructure—especially mining haulage roads—still faces various risks that could potentially cause project delays and disrupt operational efficiency. Therefore, a systematic risk identification process is necessary to ensure that project implementation proceeds in accordance with established time, cost, and quality targets. This study aims to identify and assess risks in mining infrastructure development projects using a stakeholder-based approach. This approach is employed to gain an understanding of the risks that arise from the perspectives of the parties involved in the project. The results of this study describe the dominant risks that could potentially occur in nickel mining projects, namely opposition from the local community surrounding the project, conflicts with community organizations, denial of access to project roads, and disruption of project security due to inadequate security measures by authorities. It is hoped that these dominant risks can serve as a basis for developing effective risk mitigation strategies to support the successful and sustainable development of mining infrastructure.

. The effort to re-visualize regional architectural elements combined with modern touches is known as neo-vernakular architecture. In North Sumatra, there are various ethnic groups, including Batak, Mandailing, Malay, and others, each possessing rich traditional architectural values. This study aims to identify and analyze traditional architectural elements applied to the façade of the North Sumatra Regional House of Representatives (DPRD) building. The DPRD North Sumatra building is one of the government buildings that functions as a workplace for representatives of the people, council members, and the secretariat in carrying out governmental duties and public services. The building is located on Jalan Imam Bonjol with an area of approximately 8,000 square meters. This study uses a qualitative descriptive method with data collection techniques through direct field surveys and literature studies related to the façade design of the DPRD North Sumatra building. The results show that the neo-vernakular character on the building façade is represented through several architectural elements, such as exposed columns, sunshading, opening forms, and other supporting elements that reflect a combination of traditional and modern architectural features.  

This research is motivated by the problems in manual attendance systems at schools, which remain vulnerable to fraud, time-consuming, and inefficient. The expected solution is to develop an automated attendance system based on face recognition that can operate in realtime with high accuracy. The research object is vocational high school students, with the applied method implementing the YOLO v10 algorithm for face detection, followed by the face_recognition library for identification. The instruments used include an Imou CCTV camera as the input device, a mid-range laptop as the hardware platform, and Python with SQLite as the software environment for data processing and attendance storage. The results show that the developed system achieved an average face detection accuracy of 96% under normal lighting and 91% under low lighting, with an average processing speed of 27 FPS. The implementation of an anti-duplication feature also ensured data validity by allowing each student to be recorded only once per day. In conclusion, the use of YOLO v10 in face-based attendance proved to be effective, efficient, and capable of reducing fraud. The implication of this study is that the system can be applied in both Islamic boarding schools and general schools as a modernization of attendance systems, with a recommendation for further development through web-based application and cloud database integration.

This study examines the effectiveness of urban city parks as a form of Urban Green Open Space (UGOS) in Jayapura City, focusing on Imbi Park (2,347.20 m²) and Mesran Park (2,122.88 m²). A mixed-methods approach combined direct observation of six park characteristics with a questionnaire-based rating-scale assessment of nineteen functional variables covering socio-cultural, aesthetic, and economic functions. Data were collected from 100 visitors and 31 street vendors, and analyzed using descriptive statistics and scoring analysis in accordance with Minister of Public Works Regulation No. 05/PRT/M/2008. Both parks share three dominant functions socio-cultural, aesthetic, and economic while the ecological function is present but not dominant. For Imbi Park, the socio-cultural function was moderately effective (1.8–2.0), aesthetic moderately effective to effective (2.4–2.6), and economic moderately effective (1.8–1.9). For Mesran Park, socio-cultural and aesthetic functions were moderately effective (1.8–2.2), while the economic function was ineffective (1.6). The main weaknesses across both parks are the unavailability of security posts and limited diversity of park-produce-based economic activities. The study recommends developing supporting facilities and a park-profile web portal to improve effectiveness and information accessibility.

Takaras River is a river basin that is vulnerable to pollution, particularly from the mercury usage in small-scale gold mining. This study aims to identify water quality based on mercury (Hg)and pH levels in the Takaras River. Samples were taken at two locations using a purposive sampling method. Results showed indications of mercury use on former gold mining land around the Takaras River altought the mercury content level was below 0.075 µg/L or 0.00075 mg/L in sample 1 and 2. Based on the test results, the acidity level (pH) in the two water samples from Takaras River is 3.86 and 3.84 in sample 1 and 2, compared to the maximum pH quality standard of 6-9 for Class II water, it is concluded that the scale of acidity in Takaras River is very low, indicating that the water quality in the Takaras River is highly acidic, abnormal, and shows signs of serious pollution. The implications of low pH levels in the Takaras River can cause damage to the Takaras River ecosystem, a decline in soil quality and fertility, and an increase in heavy metal toxicity in the environment surrounding the river.

Shares trading below their intrinsic value present compelling return opportunities, particularly for long‑term investors. This study aims to assess the valuation of eight food‑and‑beverage issuers listed on the Indonesia Stock Exchange (IDX) over the 2021–2025 period using two market‑based valuation instruments: the Price to Earnings Ratio (PER) and the Price to Book Value (PBV). A quantitative descriptive design was employed, and a purposive sampling technique selected eight issuers: INDF, ICBP, MYOR, ROTI, GOOD, CLEO, CMRY, and CAMP. The sectoral benchmarks obtained were an average industry PER of 22.64 times and an average industry PBV of 3.45 times. Comparative analysis reveals that INDF (PER 7.38x; PBV 0.59x), ICBP (PER 17.60x; PBV 1.83x), ROTI (PER 18.86x; PBV 2.47x), and CAMP (PER 16.59x; PBV 1.78x) are undervalued relative to the industry average and therefore merit consideration as buy candidates, while MYOR, GOOD, CLEO, and CMRY are overvalued. INDF emerges as the most attractive investment candidate because its PBV remained consistently below 1.00 throughout the observation window, a condition recognized in value‑investing literature as deeply undervalued. The findings reinforce the argument that combining PER and PBV serves as a reliable tool for identifying high‑potential stocks from a fundamental analysis perspective.

Patient safety is a top priority in healthcare services in hospitals. One of the critical elements is the accuracy of patient identification to prevent incidents such as procedural errors or medication administration. The purpose of this study was to determine the relationship between nurses' compliance in implementing SBAR communication with the accuracy of patient identification at Hospital X, West Jakarta.

This study analyzes junior high school students' errors in solving mathematics problems involving integers. This study was conducted through a systematic literature review of 12 related research articles published between 2021 and 2026. The analysis shows that students' errors in integers include contextual, procedural, and technical (calculation) errors. The most common conceptualization errors were found in the understanding of positive and negative signs and the rules for mixed operations. The main causes of errors are a lack of in-depth conceptual understanding, the habit of memorizing without understanding, and a lack of practice using concrete media. Internal factors such as learning motivation and external factors such as learning methods and media also contribute. This study recommends that the mathematics learning process emphasize meaningful conceptual understanding, the use of concrete media, and learning strategies that engage students' mathematical connection skills. Thus, difficulties in learning integers can be minimized sustainably.

Fruit rot disease is one of the main obstacles in the cultivation of guava (Psidium guajava) because it directly reduces the quality and selling value of the harvest. This research aims to identify and characterize the fungus that causes fruit rot disease in guava. The research was carried out by observing disease symptoms in the field, isolating the pathogen from infected fruit, as well as macroscopic and microscopic characterization of the fungus using Potato Dextrose Agar (PDA) media. The results of the research show that the initial symptoms are blackish brown spots on the surface of the fruit which develop into sunken lesions and spread to cause the fruit to dry out. The fungal isolate has white colonies with a flower-like pattern and forms black aservuli. Microscopic observation shows that the conidia are fusiform, insulated, with darker pigmented middle cells and have a transparent appendix. Based on these morphological characters, the fungus that causes fruit rot disease in guava is thought to belong to the genus Pestalotiopsis sp. Further research is needed through molecular approaches, such as PCR or DNA sequencing, as well as pathogenicity tests to strengthen and confirm the role of this fungus as the main cause of fruit rot disease.

Improper water management in rice cultivation can lead to water stress, which reduces productivity. Conventional monitoring has limitations on large-scale lands, necessitating more efficient remote sensing technologies. This study aims to develop a water stress identification system for rice plants in the late vegetative phase using multispectral drone imagery integrated with an Artificial neural network (ANN). The research method employs an experimental approach with six water availability levels in Karyamukti Village, Sumedang. Field reference data were obtained through soil moisture sensors converted into Available Water (AW) values. Image processing stages included orthomosaic reconstruction, leaf object segmentation, and transformation of vegetation indices (NDVI, NDRE, GNDVI, etc.) as model inputs. The results show that the ANN model with a four-hidden-layer architecture achieved training and validation accuracies of 94–95%. In the independent testing phase, the model produced an accuracy of 94.60% with an F1-Score of 93.33%. Spatial visualization of the prediction results indicates a consistent water condition distribution across rice plots. In conclusion, the integration of multispectral drones and ANN provides an accurate non-destructive solution for spatial monitoring of water availability in rice plants.

Helminth infections caused by Soil Transmitted Helminths (STH) and Taenia sp. remain a major public health concern in tropical regions, including Indonesia, particularly among elementary school children. This study aimed to identify the presence of eggs and larvae of intestinal nematodes and cestodes in fecal samples collected from elementary school children in Bekoso Village, East Kalimantan. The research employed a descriptive survey method with a cross-sectional approach, and laboratory examinations were conducted using the Kato-Katz technique. A total of 16 fecal samples were examined to detect Ascaris lumbricoides, hookworm, and Taenia sp. eggs. The results showed that 12.5% of samples were positive for hookworm eggs, 12.5% for Taenia sp. eggs, and 6.25% for Ascaris lumbricoides eggs. These findings indicate that poor personal hygiene and inadequate environmental sanitation contribute to an increased risk of intestinal helminth transmission. The study highlights the importance of preventive efforts through the promotion of clean and healthy living behaviors, consistent use of footwear, handwashing with soap, and community participation in mass deworming programs to reduce the prevalence of intestinal helminth infections among elementary school children.

This study aims to identify and minimize waste in the process of procuring Food & Beverage raw materials at Hotel PXY Jasa Bali using the Lean Inventory Management approach. Observations over one month showed that the total procurement cost reached 47% of the total revenue, exceeding the ideal limit of 35%. One of the main causes is the inefficient and lack of synchronization between divisions in the Rhapsody platform, which causes waste in the form of defects, delays, over-processing, and transportation. This study uses the Value Stream Mapping (VSM) method to map actual conditions and Process Activity Mapping (PAM) to identify the type of activity based on the waste category. In addition, root cause analysis is carried out using the Root Cause Analysis (RCA) approach. The mapping results showed that out of the total lead time of 598.44 minutes, only 278.49 minutes or 46.54% were value-added activities. This finding indicates that the procurement process is not yet efficient and needs optimization. Several recommendations were given to minimize waste, such as clearer division of tasks, improved communication with vendors, and the procurement of supporting facilities to reduce physical movement between divisions. The implementation of this lean service is expected to be able to increase the efficiency of the logistics process and reduce the company's overall operational costs.

This study was conducted to analyze the causes of occupational accidents and to identify potential hazards in the material cutting process at PT Kanaan Global Indonesia using the Job Safety Analysis (JSA) approach. The high number of occupational accidents, totaling 15 cases during the period of December 2024–May 2025, indicates the existence of gaps in occupational safety control in this area. Data were collected through direct observation, interviews with workers, and the collection of historical data from the Occupational Health and Safety (OHS) unit. Risk analysis was carried out using a risk matrix to determine likelihood and severity values, followed by JSA for each work stage. The results identified 25 potential hazards, consisting of 4 risks in the extreme category, 9 in the high category, 7 in the medium category, and 5 in the low category. High-risk hazards were predominantly found in roll cutting and cutting press machines, which are characterized by mechanical hazards. Control recommendations focus on the implementation of engineering controls such as the installation of guarding systems and safety light curtains, improvements in safe work procedures, and increased discipline in the use of personal protective equipment (PPE). These findings demonstrate that the JSA method provides a comprehensive overview of risk sources and serves as an effective basis for formulating occupational accident control strategies within the company.
