Background: Traceability systems and carbon emissions are two important factors involved in production and distribution activities. The involvement of these two factors in production and distribution activities along the supply chain will ensure the safety and quality of food through the manufacture, packaging and distribution of products with minimal costs and in an environmentally friendly way. Objective: This study aimed to develop a model of canned fish food production and distribution integration by considering traceability and carbon emissions to minimize total costs. Method: A mixed-integer linear programming (MILP) approach was used to develop mathematical models and the optimal solution of the model created was obtained using an open-source spreadsheet solver program. Results: The results show that the proposed models produce the minimum total production and distribution cost with high traceability and low carbon emissions. Conclusions: The sensitivity analysis from this study shows that there is a significant relationship between production, carbon emissions, and the total cost of production-distribution. Moreover, it was concluded that the production level, carbon emission level, and emission threshold can have a significant influence in the generation of the total carbon emissions.

The sun emits light which is solar radiation energy. This solar radiation energy can be utilized for humans, including by changing the energy of solar radiation into electrical energy. Radiation energy is changed with the help of solar or photovoltaic panels. To increase the efficiency of electricity production in solar panels, by adding Dual Axis Tracking controls. The Dual Axis Tracking Photovoltaic system is expected that solar panels will always face the sun. Because of the deviation of the direction of the solar panel to the direction of the sun will reduce the performance of generating electricity. In this study comparing 4 dual-axis tracking design methods, namely without a controller, with PID-PSO controllers that have been studied, with PDI-FA controller, and with ANFIS-FA controller. The simulation results show that ANFIS-FA is the best controller of the four methods used. This research will be a reference to compare with other methods to obtain the best method in this study.

This study aims to examine and analyze financial distress using the Altman Z-Scrore, Springate, Zmijewski, and Grover methods to predict bankruptcy in food and beverages companies listed on the Indonesia Stock Exchange for the period 2020-2023 and compare the most effective methods in analyzing financial distress. This study uses a descriptive quantitative approach method which is research conducted to determine the independent variable either one or more variables aims to analyze the problem of the relationship between one or more variables without making comparisons or connecting with other variables. The results of research using the Altman Z-Scrore, Springate, Zmijewski, and Grover methods make the Company able to analyze the Company's financial performance to prevent bankruptcy and from this study can compare between the Altman Z-Scrore, Springate, Zmijewski, and Grover methods. From the comparison results between the Altman Z-Scrore, Springate, Zmijewski, and Grover methods, the Grover method is the most effective and accurate method in analyzing financial distress with an accuracy rate of 98.4375% and an error type of 1.5625%. That way, the use of the Grover method can be used as a reference to prevent bankruptcy

This research investigates occupational stress as mediator of relationship between workload, emotional intelligence and performance of teachers in Probolinggo regency. A number of 198 teachers from both public and private secondary school in the regency were randomly selected. Data collected using questionnaires and analyzed using Structural Equation Modelling (SEM). The analysis on the validity of workload, emotional intelligence, occupational stress and performance instrument gives result above 0.139 (rtable). This tells that all instruments are valid while the reliabilities based on the analysis result in Alpha coefficient of 0.6, which is reliable. The results showed that both workload and emotional intelligence significantly influence work stress and teacher performance, and work stress is able to mediate the effect of workload and emotional intelligence on teacher performance.

Era digital telah membawa dampak signifikan pada pola asuh anak dan keharmonisan keluarga, dengan peluang dan tantangan. Di sisi positif, alat digital seperti media sosial dan panggilan video memperkuat koneksi keluarga, memungkinkan komunikasi jarak jauh, dan mempererat hubungan emosional. Namun, penggunaan perangkat digital yang berlebihan dapat mengganggu waktu berkualitas keluarga dan mengurangi interaksi langsung. Anak-anak menghadapi risiko seperti paparan konten tidak pantas, ketergantungan teknologi, serta gangguan pola tidur dan aktivitas sosial. Untuk menjaga keharmonisan keluarga, penting menemukan keseimbangan. Menetapkan batasan penggunaan teknologi, mendorong komunikasi terbuka, dan mengutamakan interaksi langsung dapat mengurangi dampak negatif sekaligus mempertahankan manfaat konektivitas. Keluarga perlu beradaptasi dengan perubahan ini secara bijak untuk mendukung hubungan yang sehat dan perkembangan positif di era digital.

Kebutuhan energi listrik yang terus meningkat akibat perkembangan teknologi dan pertumbuhan populasi memberikan tekanan besar pada sumber daya energi global. Salah satu upaya untuk mengurangi dampak lingkungan dari konsumsi energi yang berlebihan adalah melalui penggunaan teknologi penerangan yang lebih efisien, seperti lampu Light Emitting Diode (LED). Lampu LED dikenal memiliki keunggulan dalam hal efisiensi energi dan umur pakai yang lebih lama dibandingkan dengan lampu konvensional, sehingga menjadi solusi penerangan yang berkelanjutan dan ramah lingkungan. Meskipun demikian, adopsi lampu LED di kalangan masyarakat masih terbatas, terutama karena kurangnya pemahaman tentang manfaat dan efisiensi energi yang ditawarkannya. Artikel ini membahas pentingnya sosialisasi penggunaan lampu LED sebagai langkah strategis dalam menghemat energi listrik di tingkat rumah tangga dan industri. Melalui program pengabdian masyarakat, diharapkan peningkatan kesadaran tentang penerangan yang efisien dan berkelanjutan dapat tercapai, sehingga masyarakat lebih memahami dan beralih ke solusi penerangan yang ramah lingkungan. Pada akhirnya, upaya ini diharapkan dapat berkontribusi pada pengurangan konsumsi energi dan emisi gas rumah kaca, serta mendukung pencapaian target energi berkelanjutan.
