Harga emas dunia merupakan faktor eksternal yang berpotensi memengaruhi kinerja keuangan perusahaan pertambangan emas, namun hubungan keduanya tidak selalu bersifat linear mengingat kompleksitas struktur bisnis dan biaya perusahaan. Penelitian ini bertujuan menganalisis secara komparatif tren harga emas dunia dengan profitabilitas PT Aneka Tambang Tbk periode 2021–2025 menggunakan metode deskriptif kuantitatif dengan pendekatan komparatif tren. Data bersumber dari laporan keuangan konsolidasian audited PT Aneka Tambang Tbk tahun 2021–2025 serta data harga emas rata-rata tahunan yang diterbitkan oleh World Gold Council, dengan indikator profitabilitas Return on Assets (ROA) dan Net Profit Margin (NPM). Hasil penelitian menunjukkan bahwa harga emas mengalami kenaikan akseleratif dari USD 1.793,38 menjadi USD 3.518,43 per troy ounce dengan pertumbuhan kumulatif 96,2%, sementara profitabilitas perusahaan bergerak fluktuatif dengan puncak tertinggi pada 2025. Analisis komparatif terhadap empat fase pergerakan menunjukkan hubungan yang tidak konsisten dan non-linear, di mana dua fase bergerak searah, satu fase berlawanan, dan satu fase bersifat parsial, yang disebabkan oleh fluktuasi volume penjualan, ekspansi aset yang belum produktif, dan lonjakan beban pokok pembelian logam mulia dari pihak ketiga. Penelitian ini mengimplikasikan bahwa analisis profitabilitas perusahaan pertambangan perlu mempertimbangkan struktur biaya, strategi pengadaan, dan keputusan investasi secara simultan, tidak cukup bertumpu pada pergerakan harga komoditas semata.

SARIMA modeling followed the Box-Jenkins procedure, while Prophet was configured with a Lag-1 regressor, weekly and monthly seasonality, Indonesian public holidays, and log transformation. Model performance was evaluated using MAPE, MSE, and Dstat metrics. Results showed that SARIMA outperformed Prophet in MAPE and MSE across all six stock-variable combinations, with MAPE values ranging from 1.3368% to 1.9386% for SARIMA and 1.5992% to 2.2300% for Prophet. However, Prophet demonstrated marginally higher Dstat values in several series. Both models achieved "Very Good" forecasting accuracy. A web-based forecasting system was also developed using Streamlit to make the models accessible to investors.

Gatot, a fermented-cassava food, is the culinary icon of Gatot Tourism Village in Sumberpucung Subdistrict, Malang Regency. Cafe Koka, the pioneering gatot business in the area, faces two problems that hold back its growth. Its drying process still relies on sunlight, so production stops during the rainy season and the failure rate reaches 30–40%, while product presentation lacks adequate display facilities, lowering its appeal and selling value. This community-service program installed a 5 kg-per-batch cabinet dryer and two display refrigerators, accompanied by dried-gatot packaging development and staff training. The work followed a Plan-Do-Check-Act cycle combined with participatory mentoring over eight months, evaluating production and marketing indicators. After the program, drying time dropped from 2–4 days to about 4–5 hours, the product failure rate fell to 8–10%, and drying uniformity rose to about 90%. On the marketing side, impulse purchases increased by more than 40%, customer satisfaction with product display reached 4.5 of 5 (n=50), and monthly revenue grew about 175% owing to the new packaged-gatot line. Combining production and marketing technology strengthened the self-reliance of this local-food micro-enterprise.

Kappaphycus striatum seaweed is a strategic commodity producing high-value carrageenan and is widely cultivated in Indonesia. This study aims to assess the growth rate of Kappaphycus striatum which is seeded with Sargassum sp. in floating net cages (KJA) and then cultivated using the longline method in the waters of Batuhopon, Huilelot Village, Semau Island, Kupang Regency. The study was conducted during August–October 2025 using a Completely Randomized Design (CRD) with four treatments, namely P0 (5 kg Kappaphycus striatum + 0 kg Sargassum sp.), P1 (4.5 kg Kappaphycus striatum + 0.5 kg Sargassum sp.), P2 (3.5 kg Kappaphycus striatum + 1.5 kg Sargassum sp.), and P3 (2.5 kg Kappaphycus striatum + 2.5 kg Sargassum sp.). Observed parameters included daily growth rate, specific growth rate, absolute growth rate, ice-ice disease incidence, and water quality. Data were analyzed using Analysis of Variance (ANOVA). The results showed that the average daily growth rate in all treatments increased until the fifth week, but some treatments decreased in the sixth week. Treatment P0 provided the highest and most stable growth. The results of the ANOVA test showed that the treatment had no significant effect on the daily growth rate (P>0.05), but had a significant effect on the specific growth rate and absolute growth (P<0.05). The highest absolute growth was obtained in treatment P0, followed by P1, P3, and P2. The incidence of ice-ice disease increased gradually from 5% in the first week to 35% in the sixth week. Water quality parameters during the study were in the range that still supported seaweed growth, namely temperature 28–30°C, salinity 30–33 ppt, pH 7.5–8.0, depth 20 cm, and current velocity 0.3–0.4 m/s.

 The development of information technology encourages government agencies to implement digital systems in administrative management, including the filing of financial documents. This study aims to analyze the application of digitization of financial document archives in the General and Administration Section of the South Sumatra National Road Implementation Center, find out the benefits obtained, and identify obstacles faced in its implementation. The research uses a descriptive method with a qualitative approach. Data was obtained through direct observation during internship activities, documentation, internship logbooks, and literature studies. The results of the study show that the digitization of financial document archives is carried out through the stages of document completeness, scanning, digital storage, archive grouping, and document retrieval. The implementation of archive digitization provides benefits in the form of easier document searching, reducing the risk of losing archives, increasing work effectiveness and efficiency, saving storage space, improving data security, and supporting the digital transformation of government agencies. However, there are still several obstacles such as the large volume of documents, the need for high precision in the scanning process, file naming errors, device and system interference, the risk of digital data loss, limited human resources, and the simultaneous management of physical and digital archives. Therefore, it is necessary to improve the quality of digital archive management so that the benefits obtained can be more optimal.

The Free Health Check-up (CKG) is a government program designed to strengthen promotive and preventive health efforts through the early detection of risk factors, pre-disease conditions, and diseases across the community according to the life-cycle approach. As a relatively new initiative, the implementation of the CKG program in primary healthcare settings still requires further evaluation to assess implementation readiness, digital support systems, and community participation. This literature review aimed to examine the implementation of the Free Health Check-up Program in primary healthcare services. Relevant literature was retrieved from the Google Scholar database using the keyword "implementation of the free health check-up program" and was limited to open-access, full-text articles published between 2025 and 2026. The search identified eight eligible articles, which were extracted and analyzed in this review. The synthesis revealed three major themes in the implementation of the CKG program: (1) primary healthcare service readiness, (2) digitalization and reporting systems, and (3) community participation and communication strategies. Primary healthcare readiness includes the availability of human resources, infrastructure, medical equipment, consumable medical supplies, funding, service workflows, and cross-sectoral coordination. Digitalization through the SATUSEHATplatform and integrated reporting systems has the potential to improve service efficiency; however, challenges remain regarding digital literacy, internet connectivity, and the technical capacity of healthcare personnel. Community participation is influenced by knowledge, attitudes, the roles of community health volunteers, teachers, healthcare workers, and communication strategies tailored to the characteristics of the target population. The successful implementation of the CKG program requires strengthening primary healthcare systems, optimizing digital health platforms, and adopting community-based communication strategies to ensure the program is more effective, inclusive, and sustainable.

The phenomenon of infinite scrolling in digital media reflects a fundamental shift in how modern individuals experience spirituality in the digital era. The continuous flow of information creates new spaces for the search for meaning, including the human relationship with the Divine, while simultaneously introducing challenges in the form of constant distraction that disrupts deep reflection. This study aims to analyze how infinite scrolling contributes to a crisis of spiritual awareness and how digital technology functions as an ambivalent space between distraction and reflection. The research employs a descriptive qualitative method with a library research approach, using relevant academic literature and religious documents. The findings indicate that intensive digital engagement reduces opportunities for contemplation, weakens reflective capacity, and produces shallow and fragmented spiritual experiences. However, digital technology also provides broad access to spiritual resources that can be used constructively. This study concludes that the crisis of spiritual awareness in the digital era is influenced not only by individual factors but also by technological structures shaping human attention. Therefore, digital literacy that includes ethical and spiritual dimensions is essential to ensure technology supports the search for meaning.  

This study aims to analyze and compare the cabin noise levels of the Mitsubishi Destinator Ultimate variant (sunroof) and Exceed variant (non-sunroof) under various driving speed conditions. Measurements were conducted using a Sound Level Meter inside the cabin at idle, 10, 30, 50, 70, 90, and 100 km/h. Results indicate that the Ultimate (sunroof) variant consistently produces higher noise levels than the Exceed (non-sunroof) variant across all speed variations. The largest noise difference was recorded at 100 km/h at 6.50 dB, while the smallest occurred at idle at 0.05 dB. Noise levels in both variants increased significantly with increasing speed, with the sunroof variant reaching 70.00 dB and the non-sunroof variant reaching 63.50 dB at 100 km/h. This difference is attributed to gaps and seals in the sunroof panel, which allow greater noise penetration from the external environment.

This literature review analyzes the impact of data privacy issues on consumer usage intention in Indonesian e-commerce platforms. The study aims to map privacy threats and understand the phenomenon of the privacy paradox in the context of digital retail. Using a literature review method, this study synthesized findings from international journals published in the last five years from Scopus, Web of Science, and Google Scholar databases. The results show that excessive data collection, unauthorized secondary use, and data breaches significantly increase consumer privacy concerns. However, the research also confirms a privacy paradox, where consumers willingly share personal data to gain shopping convenience and promotions. The findings highlight that strong brand trust and a seamless user experience can effectively mitigate these privacy fears. Practically, this study recommends that e-commerce companies implement the Privacy by Design framework, utilize dynamic passwords (OTP), and provide transparent privacy settings as a competitive marketing advantage. Future research should explore specific regional demographics and the direct impact of new technologies like AI chatbots on consumer security perceptions.

Somongari Tourism Village in Indonesia's Purworejo Regency is the site of this research on the ways in which community-based creative economy development could promote ecotourism. As a destination rich in natural, cultural, and historical assets, Somongari demonstrates significant potential to integrate creative industries into tourism practices. Examining community involvement, entrepreneurship, and government, this study used a qualitative descriptive technique to gather data via observation, recording, and interviews.Findings reveal that creative economy initiatives—such as culinary innovation, agro-tourism, cultural storytelling, and digital promotion—strengthen destination attractiveness while generating income for residents. Innovation, inclusion, and intergenerational colaboration are greatly enhanced when women and youths are involved. Community ownership and fair distribution of benefits are reinforced via participatory governance and collective management. Limited product diversi-fication, reliance on seasonal tourism, and limitations in management competence are some of the difficulties that continue to exist. The study concludes that community-based creative economy development provides a strategic pathway for sustainable tourism by integrating economic empowerment, cultural preservation, and social participation. Strengthening entrepreneurship, enhancing digital marketing, diversifying tourism products, and fostering stakeholder collaboration are essential to improving competitiveness and resilience. This study contribute to the discourse on sustainable rural tourism by demonstrating how creative economy initiatives can serve as instruments of empowerment and sustainable destination development.

This study examines the implementation of religious freedom in Indonesia, focusing on the case of the sealing of the POUK Tesalonika House of Prayer in Teluknaga, Tangerang Regency, in April 2026. This incident reflects the tension between administrative regulations, specifically the Building Permit, and the constitutional right to freedom of religion as guaranteed in Article 28E and Article 29(2) of the Constitution of the Republic of Indonesia. This study employs a normative legal method with legislative,conceptual, and case-based approaches. The analysis reveals that the sealing action fails to meet the principle of proportionality in administrative law, and results in legal discrimination that contradicts the principle of equality before the law and the spirit of Pancasila. These findings affirm that the right to worship is a non-derogable right that cannot be diminished by technical permitting regulations. Therefore, the state must prioritize a facilitative and protective approach in regulating places of worship, to guarantee freedom of religion and uphold Indonesia’s integrity as a democratic and tolerant rule of law state.

Artificial Intelligence (AI) has increasingly influenced higher education, including learning practices among students of Islamic Education (PAI). Applications such as ChatGPT, Claude AI, and Gemini are widely used to support academic activities, including information searching, understanding course materials, idea generation, and assignment completion. This study aims to examine the use of AI among PAI students and analyze its implications for critical thinking skills. A qualitative descriptive approach was employed at the Islamic Education Program of UIN Salatiga. Data were collected through written interviews with 12 students selected using purposive sampling and analyzed using an interactive data analysis model. The findings reveal that AI has become an important part of students’ academic activities due to its perceived usefulness and ease of use. Most participants demonstrated critical thinking behaviors by verifying AI-generated information, comparing multiple academic sources, and evaluating the accuracy of responses before using them for academic purposes. Nevertheless, excessive dependence on AI was found to potentially reduce students’ independent learning and analytical engagement. The study concludes that AI has a dual impact on critical thinking: it can enhance critical thinking when used reflectively and responsibly, but it may also weaken cognitive involvement when relied upon excessively. Therefore, strengthening AI literacy, digital literacy, and critical thinking skills is essential in higher education learning practices.

In the digital era, job-seeking mechanisms have evolved through e-recruitment platforms, particularly for Gen Z fresh graduates. However, seamless digital access does not inherently trigger a high intention to apply for jobs, suggesting a complex interplay between internal psychological states and external technical factors. Objective: This investigation empirically examines the extent to which self-efficacy and the effectiveness of e-recruitment systems influence the intention to apply for jobs among Gen Z fresh graduates in Tasikmalaya Regency. Methodology: This study employed an explanatory quantitative approach involving 80 subjects selected via purposive sampling. Data evaluation was conducted through Multiple Linear Regression analysis using SPSS software. Findings: The research data demonstrates that both self-efficacy and digital recruitment systems exert a positive and significant impact on job application intentions, both independently and simultaneously. Furthermore, self-efficacy was identified as a more dominant predictor compared to recruitment technology. An R-Square value of 0.590 indicates that these two variables account for 59% of the variation in job application intentions. Implications: Companies are encouraged to continuously modernize their recruitment infrastructure while considering the psychological readiness of applicants and strengthening corporate branding to attract high-potential new graduates.

This research was conducted at the Semarang City Public Works Department, particularly in the secretariat section responsible for correspondence administration and public information management (PPID). The study focuses on the conventional management of letter disposition, which makes it difficult for PPID officers to monitor letter status quickly, reduces process transparency, and may cause delays in decision-making and public services. This research aims to develop and implement a Disposition Monitoring Information System (SIMODIS) to digitize correspondence administration so that it becomes more effective, efficient, transparent, and accountable. The study uses ASTRID Analysis to identify strategic issues and a Design Thinking approach consisting of the Empathize, Define, Ideate, and Prototype stages. Empathy Map and Persona were also used to understand user needs. System testing was conducted using Black Box Testing to assess functionality and the System Usability Scale (SUS) to evaluate user experience. The results show that SIMODIS was successfully developed with features such as an admin dashboard, digital disposition forms, and a public mail status search portal. The SUS score reached 83, categorized as Excellent, indicating high usability and user acceptance.

The KRI Nagapasa Class is a submarine of the Indonesian Navy that has the capability to deploy sea mines, launch anti-surface missiles, and release countermeasure torpedoes. However, to face the increasingly complex dynamics of the regional strategic environment, it is necessary to increase combat power through the installation of a Sub Launch Missile weapon system. Until now, the Indonesian Navy does not have a submarine equipped with this underwater missile, especially in the Chang Bogo class. This study aims to analyze and determine the most appropriate choice of Sub Launch Missile missiles to support submarine training and operations. The method used is the Analytic Hierarchy Process (AHP) with a quantitative approach. The results of the ranking of five respondents showed that the SM-39 Exocet missile was in first place with a value of 0.46424 followed by the CM-708UNB with a value of 0.41461 and the UGM-84 Harpoon with a value of 0.12115. The SM-39 Exocet missile was chosen as a priority because it has technical specifications that best meet the operational needs of the Indonesian Navy (TNI AL), as well as significantly contributing to enhancing the deterrence effect and combat capability of the Nagapasa-class submarines.

Analyzing the freshwater needs on Landing Platform Dock (LPD) type ships in the Amphibious Unit of Koarmada II, with a focus on the implementation of the Reverse Osmosis (RO) system to supply freshwater at sea. The problem faced is the limited supply of freshwater on ships operating far from external freshwater sources. This study uses a qualitative approach with interviews, observations, and documentation as data collection methods. The results of the study indicate that the RO system can improve the efficiency of freshwater supply, although technical challenges such as maintenance and crew training still need to be addressed. Optimal implementation of the RO system can support the logistical independence of the ship during long-term operations in remote waters. This study is expected to serve as a reference for the development of freshwater supply systems on Indonesian warships.

The Indonesian Archipelagic Sea Lane II (ALKI II) constitutes a strategic route stretching from the Sulawesi Sea to the Indian Ocean with trade values reaching USD 1.5 million daily and traversed by more than 36,773 vessels annually. The complexity of maritime security threats in this region has increasingly intensified following the relocation of the capital city to East Kalimantan, thereby demanding an effective decision support system to assist Indonesian Warship Commanders in making operational decisions that are rapid, accurate, and in accordance with applicable legal provisions. This research employs a qualitative approach through in-depth interviews with four maritime expert sources, with data analysis using NVivo 12 software. Analysis results identified maritime operational complexity and the urgent need for a comprehensive decision support system. These findings subsequently served as guidance in designing a Decision Support System (DSS) with a tab-based interface that integrates international legal frameworks such as UNCLOS 1982, Law No. 3/2025 on TNI, and related national regulations to generate structured action recommendations along with their legal foundations. Research findings demonstrate that the developed DSS successfully integrates operational, legal, and situational aspects to support decision-making that is rapid, accurate, and legally compliant. This system has proven to enhance the effectiveness of Indonesian Warship Commanders in addressing the complexity of maritime security (KAMLA) challenges in ALKI II through the provision of legally-based action recommendations from national and international frameworks accessible in realtime during operational situations.  

As a maritime nation with vast sea territories, Indonesia faces significant challenges in safeguarding its waters, particularly in strategic regions such as the Natuna Sea. This area is vulnerable to various threats, including territorial violations, marine resource theft, and illegal underwater activities. This study aims to formulate a concept for the utilization of Autonomous Underwater Vehicles (AUVs) as an alternative solution to enhance underwater security systems in the region. The method employed is Research and Development (R&D), adopting model development steps and complemented by a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis to assess the feasibility and effectiveness of AUVs in the context of Indonesian maritime defense. The research findings indicate that the main strength of AUVs lies in their technological capability to effectively detect underwater threats. Although they have weaknesses, such as high operational costs, dependency on imported components, and limitations in battery endurance and sonar capabilities, these factors do not significantly hinder AUV effectiveness. Major opportunities arise from global technological advancements, yet challenges remain due to insufficient government policy support. The threats faced include the risk of sabotage and extreme weather conditions. Therefore, the recommended strategies are to maximize the use of technology, strengthen supporting regulations, and address logistical and financial barriers to realize effective and sustainable AUV operations in the Natuna Sea.

However, there are still elderly people who are reluctant to carry out regular physical activity, so the health status and quality of life of the elderly also decline. Aims: This systematic review aims to identify the relationship between social cognitive theory (SCT) on physical activity in the elderly. Methods: This systematic review method approach is based on PRISMA. This systematic review examines several research articles from journal databases, namely PubMed and ScienceDirect, and obtained 13 articles in 2019-2024. The keywords used in the search are “Social Cognitive Theory”, “SCT”, “Physical Activity”, “PA”, and “Elderly”. The articles reviewed met the inclusion criteria, namely relevant article topics, original research articles in English, and publications in the last five years. The eligibility criteria were then assessed separately using the JBI Critical Appraisal Checklist tool.  Results: From a total of 13 articles reviewed, it can be concluded that the majority of articles explain how important the social cognitive patterns that elderly people must have in relation to the physical activity of the elderly, such as predicting the physical activity of the elderly, increasing the exercise behavior of the elderly, influencing the level of physical activity for people with chronic diseases, and adjusting physical activity with the abilities of the elderly. The higher an elderly person's social cognition, self-efficacy, encouragement, and social support to be able and willing to carry out physical activities in accordance with the elderly's abilities and physical condition. Conclusion: The social cognition of the elderly places more emphasis on the ability of the elderly to learn things around them, so that the elderly have self-efficacy, encouragement, and social support to do things in according to their goals and beliefs. Health workers in provide health services to the community, social cognitive theory can be used for alternative to increase the physical activity of the elderly. A personalized smartphone-based intervention based on SCT is highly effective for promoting physical activity in older adults.
