Abstract

Mikroplastik adalah potongan plastik yang sangat kecil dan dapat mencemari lingkungan. Meskipun ada berbagai pendapat mengenai ukurannya, mikroplastik didefinisikan memiliki diameter yang kurang dari 5 mm. Penelitian ini bertujuan unuk menganalisis kelimpahan mikroplastik pada kolom permukaan air di perairan pesisir Takisung. Perairan pesisir Takisung memiliki nilai kelimpahan mikroplastik sebesar 7100 partikel/m3 yang menunjukan bahwa perairan ini sudah tercemar oleh adanya mikroplastik, didominasi mikroplastik jenis line dengan total kelimpahan 5100 partikel/m3, kemuadian film dengan total kelimpahan 1400 partikel/m3, dan yang paling rendah fragment dengan total kelimpahan 600 partikel/m3.

Abstract

Salah satu sumber daya alam yang sangat besar manfaatnya bagi kesejahteraan manusia adalah Hutan. Penelitian ini bertujuan menghitung produktivitas penyaradan kayu dengan dua teknik yaitu Teknik Winching dan Tanpa Winching. Penyaradan merupakan kegiatan yang sangat berpengaruh dalam proses pemanenan hutan, tanpa penyaradan kayu yang ada akan sulit untuk dikeluarkan dari dalam hutan. Indikator keberhasilan pemanenan kayu dipengaruhi oleh faktor kondisi alat, teknik penyaradan dan kondisi lapangan. Berdasarkan hasil penelitian produktivitas penyaradan kayu dengan traktor Skidder komatshu D85.ESS dengan teknik Winching pada kelerengan 25-75% yaitu 1.197,67 m3/jam atau rata-rata 29,94 m3/jam, sedangkan penyaradan tanpa Winching pada kelerengan 0-25% produktivitasnya yaitu 580,46 m3/jam atau rata-rata 14,51 m3/jam.

Abstract

This research aims to analyze the supply chain and marketing chain of freshwater fish in the West-Southern Region of Aceh Province, Indonesia. The research activities took place from May to July 2022, with data collection continuing in 2023. The determination of data collection locations used purposive methods, and data collection was conducted through survey methods. Data were obtained from fish traders in four  markets: Ujong Baroh Meulaboh Fish Market, Blang Pidie Market, Nagan Raya Market, and Krueng Sabe Fish Market. Data analysis was conducted descriptively. The research results indicate that the supply chain includes fish farmers, partner traders, collector traders, retailers, and consumers, and there are two supply chains based on regions: inter-insular and intra-region. The dominant types of freshwater fish supply are catfish and tilapia. Tilapia has a higher price compared to catfish. Tilapia is dominant in the Ujong Baroh market, while catfish is dominant in the Blang Pidie  market. It has become a substitute when sea fish are scarce or expensive in the market. Based on the value chain analysis, a margin ranging from 10% to 30% was obtained. Partner traders play a significant role in production activities and the supply chain due to cooperation in input-output factors. Challenges in the freshwater fish supply consist of seeds and feed, with seeds mostly supplied from outside West-South, accounting for more than 80%.. Addressing freshwater fish supply challenges in Southwest Aceh requires an integrated supply chain approach enhancing hatchery systems and fry distribution upstream, improving aquaculture infrastructure and feed subsidies at the production level, and establishing collection centers, cold storage, and modern markets in key districts to strengthen distribution, stabilize prices, and improve food security.

Abstract

This study aims to analyze the influence of school culture, work attitudes, stress management, and job satisfaction on teachers' organizational commitment in schools. The study used a quantitative, survey-based approach. Data were collected through questionnaires distributed to teachers and analyzed using path analysis to examine relationships among variables and to measure direct and indirect effects. The results indicate that school culture and work attitudes have a direct, positive, and significant effect on teachers' stress management. Furthermore, school culture, work attitudes, and stress management have a direct, positive, and significant effect on teachers' job satisfaction. The coefficient of determination indicates that these four variables together explain 74.8% of the variation in teachers' organizational commitment, while factors outside the research model influence the remaining 25.2%. These findings confirm that teachers' organizational commitment is shaped by the interaction of organizational, work behavior, psychological, and affective factors. The implications of this study suggest that strengthening teachers' organizational commitment can be achieved through developing a supportive school culture, fostering professional work attitudes, and enhancing job satisfaction in an integrated manner, thereby improving teacher performance and the effectiveness of educational organizations.
