The high dependence of national food on imported commodities, especially wheat, creates vulnerabilities in the aspect of National Food Security. This study examines the position and role of Modified Cassava Flour (Mocaf) Micro, Small, and Medium Enterprises (MSMEs) in Padi Village as a pillar of local food diversification and its implications from the perspective of Constitutional Law (HTN) on the internal sector (community, MSMEs, and Village Government). Mocaf, as a gluten-free cassava derivative product, has the potential to be a substitute for wheat flour. The research method used is Empirical Normative Law with a conceptual and legislative approach, reinforced by primary data regarding the operational model of MSMEs in Padi Village. The results of the study indicate that Mocaf MSMEs at the village level act as strategic legal subjects in realizing Article 33 paragraph (3) of the 1945 Constitution (UUD 1945) and Law Number 18 of 2012 concerning Food. The implications of HTN are seen in the need for regulatory harmonization and strengthening village autonomy through budget policies and assistance that ensure the sustainability of production and marketing. The position of MSMEs demands stronger recognition of the internal role of villages in the national food governance structure.

Learning media is a tool used to convey messages so that it can stimulate students' thoughts, feelings, attention, and willingness in the learning process. This study aims to determine the effectiveness of using KoKaMi media, a three-dimensional media combined with language games, in improving Arabic vocabulary mastery of eighth-grade female students of SMPIT An Nur Sragen. This study uses a quantitative approach with an experimental method and a pre-experimental design of one group pretest–posttest type. The study population consisted of 22 female students and all were sampled through a total sampling technique. Data collection was carried out through tests, interviews, observations, and documentation, while data analysis used descriptive statistics, prerequisite tests, and hypothesis testing with the help of SPSS. The results of the analysis showed that the data were not normally distributed so the Wilcoxon Signed Rank Test was used. The test results showed a significance value of 0.000 smaller than 0.05, which means H0 is rejected and Ha is accepted. These findings prove that KoKaMi media is effective in improving Arabic vocabulary mastery. Therefore, KoKaMi media can be used as an alternative innovative learning media that helps students understand vocabulary more actively, enjoyably, and meaningfully. The implications of this research indicate that the use of game-based media can increase learning motivation, class participation, and learning interactions, so teachers are advised to utilize similar creative media as an effective and student-centered language learning strategy in learning practices at school consistently and sustainably.

Disputes over unpaid insurance claims are a problem that frequently arises in insurance practice and can harm consumers both financially and psychologically, while also reducing public trust in the insurance industry. Such disputes are generally triggered by differing interpretations of policy provisions, alleged breaches of the good-faith principle, and administrative obstacles, which ultimately lead to civil conflicts between the insured and the insurer. To provide access to dispute resolution that is faster, fairer, and more affordable than litigation, the Financial Services Authority (Otoritas Jasa Keuangan/OJK) established the Alternative Dispute Resolution Institution for the Financial Services Sector (Lembaga Alternatif Penyelesaian Sengketa Sektor Jasa Keuangan/LAPS SJK) through OJK Regulation No. 61/POJK.07/2020. This study aims to analyze the mechanism for resolving disputes over unpaid insurance claims through LAPS SJK and to assess its effectiveness in providing legal protection and legal certainty for consumers. The research method employed is normative legal research using a statutory approach and a conceptual approach, through an examination of primary, secondary, and tertiary legal materials related to contracts, insurance, consumer protection, and alternative dispute resolution. The findings show that LAPS SJK has the authority to handle civil disputes in the financial services sector, including insurance disputes, provided that the parties have a written agreement and have first pursued internal dispute resolution (Internal Dispute Resolution/IDR). Dispute resolution at LAPS SJK is conducted through mediation and arbitration. Mediation is facilitated by a mediator to encourage the parties to reach a settlement agreement, which may be reinforced into a Deed of Settlement (Akta Perdamaian) that is final, binding, and enforceable. If mediation fails, arbitration offers a more determinative resolution through a final and binding award that can be enforced after being registered with the District Court. Overall, LAPS SJK is considered effective because its procedures are structured, time-bound, and provide a fee waiver for mediation in retail and small-claim cases up to IDR 750,000,000. However, its effectiveness remains conditional, as it depends on the existence of a written agreement between the parties, the obligation to undergo IDR, and good faith in the mediation process.

This study analyzes the performance of three types of controllers—PID, Fuzzy-PID, and Model Predictive Control (MPC)—in maintaining water level stability in a dam system. Proper water level regulation is essential to prevent flooding, ensure adequate water distribution, and maintain the structural safety of the dam. Previous studies have widely implemented PID and Fuzzy-PID controllers; however, MPC offers significant advantages through system prediction and multivariable optimization. This research compares the performance of the three controllers through simulation analysis using a second-order mathematical model. The results indicate that MPC has the potential to deliver a faster settling time and a smaller steady-state error compared to PID and Fuzzy-PID, although it requires higher computational complexity.

Moreover, SGCA does not significantly influence SBP. These results suggest that while Green HRM Practices can enhance competitive advantage, a more nuanced approach may be required for SMEs to fully leverage innovation and stakeholder collaboration for long-term sustainable business performance. This research contributes to the growing body of knowledge on green strategies in SMEs, offering practical recommendations for business leaders to integrate sustainability into their operational strategies. The study aligns with Sustainable Development Goals (SDG) 8, 9, 12, and 13, aiming for responsible production and climate action.

This study explored how a teacher’s writing habit functions as emotional expression within a demanding teaching routine. Specifically, it examined four aspects like writing as emotional release, writing as reflective practice, writing within a demanding teaching routine, and writing as an emotional coping strategy. A qualitative single-case study design was employed. The participant was one female teacher at SD Negeri 060 Pekkabata, Polewali Mandar, Sulawesi Barat, who had a very hectic schedule including full-time teaching, administrative duties, and private tutoring. Data were collected through semi-structured interviews conducted via Zoom and WhatsApp chat, as well as document analysis of the teacher’s syllabus, lesson plans, blog, Instagram posts, journal book, and mobile phone notes. Thematic analysis was used to analyze the data. The findings revealed that writing served as a powerful emotional release, helping the teacher process anxiety and accept difficult situations. Reflective writing occurred primarily during professional training periods and motivated her to improve classroom practice. Despite her demanding routine, the teacher maintained a writing habit by using multiple platforms, writing during natural breaks, and prioritizing short, happiness-focused notes. She considered writing equally effective as talking to others for emotional expression and strongly recommended writing to fellow teachers. The study concludes that a flexible writing habit focused on emotional release and small positive moments can be a sustainable, low-cost coping strategy for teachers facing overwhelming professional demands. These findings have implications for teacher well-being program and teacher education.

This research offers valuable insights for tourism SMEs and policymakers, emphasizing the importance of global leadership capabilities and internal organizational dynamics in enhancing sustainable tourism.

Sea Surface Temperature (SST) is an important parameter in oceanographic studies because it influences climate dynamics, ocean circulation, and marine ecosystems. Continuous monitoring of SST in open sea areas requires a reliable system capable of operating autonomously. This study develops a solar-powered ocean buoy designed to measure sea surface temperature while simultaneously evaluating the performance of a solar panel as the main energy source. The system uses a DS18B20 sensor to measure SST and an INA219 sensor to monitor the voltage, current, and power of the solar panel, while an ESP32 microcontroller functions as the central data processing unit. The results show that sea surface temperature tends to remain relatively stable with small daily variations, whereas the temperature and performance of the solar panel exhibit larger fluctuations due to direct exposure to solar radiation and changing weather conditions. Solar panel performance also shows significant variations in current and power depending on the intensity of sunlight. To analyze the influence of SST variations on solar panel performance, a statistical analysis using Analysis of Variance (ANOVA) was conducted. The ANOVA results, based on the calculated F-value and the significance value (p-value) at a confidence level of α = 0.05, indicate that SST variations have a significant effect on solar panel performance, demonstrating that the proposed solar-powered buoy system can operate autonomously and has potential for long-term SST monitoring in offshore areas.

The increasing demand for electrical energy and the limited availability of fossil fuels have driven the development of renewable energy sources, including marine current energy, which remains underutilized in coastal and remote maritime regions. This study presents the design and realization of a small-scale marine current power generation prototype using a horizontal axis propeller turbine with a NACA S814 blade profile and analyzes the effect of turbine rotational speed on electrical power output. The system converts marine current kinetic energy into mechanical energy through turbine rotation and subsequently into DC electrical energy using a generator, which is stabilized by a Buck–Boost Converter and Maximum Power Point Tracking (MPPT) for charging a 12 VDC battery. Real-time monitoring of electrical and mechanical parameters is implemented using an Internet of Things (IoT)–based system comprising an ESP32 microcontroller, a PZEM-017 sensor, and an RPM sensor. Experimental results demonstrate a positive correlation between water flow rate, turbine rotational speed, and generator output voltage. The system begins operating at a minimum flow rate of 35.2 L/s at 56 RPM, producing 0.2 V, while optimal performance is achieved at 45.3 L/s and 516 RPM, generating up to 13.3 V. These results indicate that the proposed prototype is a viable alternative renewable energy source for marine applications.

This research aims to design and develop a prototype wave power plant that utilizes the vertical motion of a buoy as a source of mechanical energy, which is then converted into electrical energy using a recoil starter mechanism. The system is designed to be installed at the stern of a prototype ship. The vertical movement of the buoy caused by ocean waves is transmitted to the recoil starter through a drive rope, producing a stable one-way rotational motion. This rotation is further transmitted to a gearbox to increase rotational speed before driving a DC generator. The electrical energy generated is stored in a 12 VDC battery, supported by a buck–booster converter to stabilize the output voltage. This study employs an experimental engineering approach to evaluate system performance based on empirical test data. The main components of the system include a buoy as a wave energy collector, a recoil starter as the initial rotating mechanism, a DC generator as the electrical energy producer, a buck–booster converter as a voltage regulator, a 12 VDC battery as an energy storage unit, and a monitoring system based on an ESP32 microcontroller integrated with a PZEM-017 sensor. Experimental results show that the recoil starter operates effectively in driving the generator under both no- load and buoy-loaded conditions. Increases in generator rotational speed are directly proportional to increases in output voltage and current. The PZEM-017 sensor demonstrates a high level of measurement accuracy, approaching 100% when compared with a multimeter. Overall, the proposed wave power generation system functions reliably and shows potential for further development as a small-scale alternative renewable energy source.

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.
