Academic stress is a common challenge experienced by students due to the burden and pressure in higher education environments. This study conducted a systematic literature analysis to evaluate the effectiveness of mindfulness-based psychological interventions and social support in addressing academic stress. By reviewing various empirical studies from leading journals, it was found that mindfulness—through techniques such as Mindfulness-Based Stress Reduction (MBSR)—is beneficial in reducing stress, anxiety, and improving students' emotional regulation and learning focus. In addition, social support from family, friends, and the campus environment acts as a stress buffer by providing emotional support and a sense of connectedness. An approach that combines mindfulness and social support has shown more effective results in helping students manage academic stress. Therefore, it is recommended that higher education institutions develop programs that integrate these two interventions to improve students' mental well-being sustainably.

The demand for chocolate continues to increase along with high public consumption. One of the main components in chocolate formulation is fat, which generally comes from cocoa butter. However, the availability of cocoa butter is limited and the price is relatively high, so a more economical and easily obtained substitute material is needed locally to support the sustainability of the chocolate industry. This study aims to examine the potential of palm oil fractions, especially palm stearin and olein, as a partial substitute for cocoa butter (Cocoa Butter Substitute/CBS) in chocolate formulations. The study was conducted through a literature review of scientific journals published in the last 10 years, which included chemical, physical, and sensory analysis data on palm oil-based chocolate products. The results of the study showed that stearin increased the melting point and firmness of the product, while olein produced a softer texture and a smoother melting sensation. Sensorially, olein-based formulations showed a higher level of acceptance than stearin, especially in color, aroma, taste, and texture attributes. In addition, palm oil fractions do not produce trans fats, and are able to maintain the balance of solid and liquid fats, while supporting the stability of the product emulsion. This study shows that palm oil fractions, especially through the right combination of stearin and olein, have great potential as a substitute for cocoa butter without reducing physical or sensory quality, thus supporting the sustainability of chocolate production in the future.

. Freezing is a widely used preservation method to extend the shelf life of food, yet conventional freezing often produces large ice crystals that damage tissue structures and reduce product quality. This study aims to evaluate the effectiveness of ultrasound-assisted freezing technology in improving the quality of frozen food. A literature review method was employed, focusing on scientific publications from 2015 to 2025. The results show that ultrasound application, particularly High-Intensity Ultrasound (HIUS), can accelerate the freezing rate by enhancing ice nucleation and improving heat transfer efficiency. The formation of smaller and more uniformly distributed ice crystals helps preserve the structural integrity of food and reduces water loss during thawing. The effectiveness of this technology varies depending on the type of food material, temperature, duration, and ultrasound intensity. In animal-based products, it helps maintain texture and color, while in plant-based materials, it preserves moisture content and firmness. However, excessively high intensity may pose a risk of protein denaturation, especially in sensitive materials such as fish. These findings suggest that ultrasound-assisted freezing is a promising innovative solution to improve both the quality and efficiency of the food freezing process.

This study aims to analyze the effect of product arrangement on consumer purchasing decisions at Alfamidi Jl. Tuasan, Medan. Product arrangement is a crucial visual merchandising strategy in the modern retail industry to attract consumer attention and increase sales. The study used a quantitative approach with an associative method, involving 30 respondents selected through accidental sampling techniques. Data were collected using a questionnaire with a 5-point Likert scale and analyzed using simple linear regression with the help of SPSS version 25. The results showed that product arrangement had a positive and significant effect on consumer purchasing decisions with a coefficient of determination (R²) of 90.2%. The regression equation Y = 1.245 + 0.675X shows that every one unit increase in product arrangement will increase purchasing decisions by 0.675 units. The t-test produced a calculated t value of 16.071> t table 2.048 with a significance of 0.000 <0.05, confirming the research hypothesis. This finding confirms that product layout elements such as ease of access, visual appeal, and layout comfort play a vital role in influencing consumer behavior and increasing the effectiveness of retail marketing strategies.

Sholawat is a request to obtain blessings and respect for the Prophet Muhammad SAW. Sholawat diba' is a form of worship to get closer to Allah SWT. The Sholawat assembly was held in the community with the aim of increasing religious knowledge and belief, which in turn encourages the implementation of religious teachings as a way for the community to foster friendship between residents. Community service activities through Diba'an have succeeded in achieving an important goal, namely forming the religious character of Tropodo village. Not only that, this activity has also succeeded in increasing the spiritual values, social values ??and cultural values ??of the Tropodo village community. The Diba Sholawat Assembly activity held together with IPNU and IPPNU in Tropodo Village, Waru District, Sidoarjo Regency, has a significant role in shaping the religious character of teenagers. Through this activity, teenagers are not only trained to love and practice Islamic teachings, but also in the form of love for the Prophet Muhammad SAW

Community Service Activities are a real form of students' social concern for the surrounding environment. Five students of the Management Study Program at Borneo Tarakan University carried out community service in collaboration with local MSME actors through an activity entitled "Sharing Chocolate Bread as a Form of Social Concern". This activity was held on Sunday, May 4, 2025 at 11.00–12.00 WITA at the Hidayah Nurul Yaqin Orphanage, Jl. Sesanip, Karang Anyar, Tarakan, North Kalimantan. The activities included welcoming, praying together, introductions, distributing chocolate bread produced by MSMEs, and documentation. The children of the orphanage welcomed enthusiastically, a warm and pleasant atmosphere was created, and positive interactions were established between students, MSMEs, and the children of the orphanage. This activity brought happiness to the children, became a means of social learning for students, and promoted products for MSMEs. This collaboration shows that synergy between academics and business actors can provide sustainable social contributions.
