Optimal resource management is a key factor in enhancing efficiency and profitability in a business. The simplex method, as one of the approaches in linear programming, provides an analytical tool to solve optimization problems with specific constraints. This research aims to apply the simplex method to optimize business profits in a case study. The data used includes production capacity, costs, and market demand. Through the application of this method, an optimal solution was obtained, showing the combination of products and resource allocation that generates maximum profit. The findings demonstrate that the simplex method is highly useful in supporting strategic actions, particularly in efficient resource allocation. Thus, this method can serve as a reference for business practitioners in designing strategies to sustainably increase profitability. Additionally, it is expected that the results of this study can actively contribute to supporting the development of effective and sustainable business strategies.
 

Fenomena dispensasi kawin di Pengadilan Agama Martapura menjadi perbincangan hangat, mengingat semakin tingginya angka permohonan dispensasi kawin yang diajukan oleh pihak yang ingin menikah di bawah usia yang diatur oleh perundang-undangan. Penelitian ini bertujuan untuk mengkaji dispensasi kawin dari perspektif hukum positif dan syariah, serta implikasinya terhadap kehidupan sosial masyarakat. Secara yuridis, dispensasi kawin yang diajukan ke Pengadilan Agama harus memenuhi syarat-syarat yang telah diatur dalam Undang-Undang Nomor 16 Tahun 2019 tentang Perubahan atas Undang-Undang Nomor 1 Tahun 1974 tentang Perkawinan. Namun, terdapat ketegangan antara ketentuan hukum negara dan pandangan agama terkait batasan usia minimal untuk menikah. Dari sisi syariah, pernikahan di bawah usia yang ditetapkan dapat menimbulkan berbagai permasalahan baik dari segi kesehatan, psikologis, maupun sosial, meskipun dalam beberapa kondisi, dispensasi kawin dipandang sebagai solusi bagi individu yang berada dalam situasi darurat. Penelitian ini menggunakan pendekatan kualitatif dengan studi kasus pada Pengadilan Agama Martapura, dengan menganalisis keputusan-keputusan yang dikeluarkan terkait dispensasi kawin. Hasil penelitian menunjukkan bahwa meskipun hukum negara memberikan ruang untuk dispensasi, namun nilai-nilai syariah tetap mengedepankan perlindungan terhadap hak-hak anak dan perempuan. Oleh karena itu, kebijakan pengadilan perlu memperhatikan aspek-aspek perlindungan tersebut dalam memutuskan setiap permohonan dispensasi kawin. Penelitian ini diharapkan dapat memberikan kontribusi dalam pengembangan hukum keluarga Islam, khususnya terkait dengan usia pernikahan dan dispensasi kawin di Indonesia.

Linguistics plays a crucial role in studying and understanding the structure of language, including in the context of Arabic. The Arabic language, with its complex system of morphology, syntax, and phonology, requires an in-depth linguistic approach to analyze its grammatical structure. This study aims to explore how linguistic theories, such as phonology, morphology, syntax, and semantics, contribute to understanding the basic structure of Arabic. Through linguistic approaches, a clearer and more structured understanding of sentence structure, word patterns, and the relationships between language elements can be achieved. This paper also discusses the challenges faced in applying linguistic theories to Arabic, as well as the importance of a linguistic approach in teaching Arabic to non-native speakers. The findings of this study are expected to provide broader insights into the role of linguistics in learning and teaching Arabic more effectively and systematically. 

Objective: To investigate the effects of constant-width and varied-width parachute running training on the 100-meter sprint performance of athletes from the North Medan Athletic Club in 2023 and to determine which training method is more effective. Methods: The entire population of 10 athletes from the North Medan Athletic Club was analyzed. The athletes underwent pretest and post-test measurements for their 100-meter sprint times. They were divided into two groups: one group was trained with constant-width parachute running, and the other group was trained with varied-width parachute running. Pretest and post-test data were analyzed using SPSS 21. Normality tests were conducted to ensure data distribution. Homogeneity of variance was tested to compare the variances between the two groups. A t-test was used to determine the significance of the differences in sprint times before training and after training, as well as the difference between constant and varied-width training. Results: All data were normally distributed and showed homogeneity. The t-test showed a statistically significant improvement in sprint times for athletes in both the constant-width (p < 0.05) and varied-width (p < 0.05) parachute running groups. Furthermore, a significant difference was found between the constant-width and varied-width training methods, with varied-width training showing a greater effect in increasing the sprint speed of athletes at the North Medan Athletic Club.

Early Childhood Education (PAUD) has a crucial role in shaping children's character and basic knowledge, including in terms of environmental awareness. On the other hand, many families in Indonesia are facing economic challenges that require intervention to improve their well-being. This research aims to develop environment-based social entrepreneurship as a tool for family empowerment through early childhood education. Environment-based social entrepreneurship not only aims to create profitable businesses, but also to support the sustainability of nature, thus having a positive impact on both the family economy and environmental conservation. Through literature research, it was found that the integration of social entrepreneurship with early childhood education can provide dual benefits: increasing environmental awareness in children and empowering parents with eco-friendly entrepreneurial skills that can increase family income. Collaboration between educational institutions, the government, and the community is also considered very important to ensure the successful implementation of this program.

Psychological factors are one of the factors that support athlete performance. Therefore, there is a need for psychological training to overcome various psychological problems, especially the concentration and performance of karate athletes. This study aims to examine the effect of imagery training on the concentration and performance of kata karate athletes based on gender. This research uses an experimental method with a post-test only design. The sample used in this research was 10 karate kata Gokasi athletes from Bandung City, consisting of 5 female and 5 male athletes aged 11-13 years. Intensive imagery training was given as a research treatment, where they would imagine detailed word movements with an exercise duration of 10-15 minutes per session, frequency 3-4 times a week for 4 weeks. Measurements were carried out in two aspects, namely concentration using the Concentration Grid Test (CGT) and performance using the jury’s assessment through mini-events. Data analysis was carried out using the SPSS Version 27 statistical test. The results of the study showed that the impact of visualization training on the focus and performance of karate kata athletes, both male and female, varied greatly. Male athletes outperformed female athletes in the concentration variable, while female athletes outperformed male athletes in the performance variable. Thus, it can be said that imagination training is one of the exercises that can be used to help karate kata athletes, both male and female, to be more focused and perform better.

This research aims to determine the influence of painting with natural materials on the development of elementary school children's creativity. Through literature studies, this research analyzes various relevant publications to identify the concept of creativity, the benefits of using natural materials in art learning, as well as the results of previous research related to this topic. The research results show that painting activities with natural materials have great potential in stimulating children's creativity through various aspects, such as critical thinking skills, imagination and self-expression. Apart from that, this activity can also improve fine motor skills, hand-eye coordination, and environmental awareness in children. The use of a variety of natural materials and their multisensory nature can provide a fun and meaningful learning experience for children, thereby encouraging their interest and motivation to learn.
