Abstract

This study aims to analyze the Factors Affecting Coffee Exports in Indonesia. The data used in this study is secondary data from 1990-2016 obtained from the Central Statistics Agency (BPS) and the Indonesian Ministry of Agriculture. The data analysis method used is Vector Auto Regression using Eviews Software. The results of the study can be concluded that partially coffee imports have no effect and are positive on coffee exports in Indonesia, partially inflation does not have an effect and negatively affects coffee exports in Indonesia, partially the exchange rate does not have an effect and is positive for coffee exports in Indonesia and partially production does not have an effect and is positive for coffee exports in Indonesia as well as simultaneously the variables of imports, inflation, exchange rate and production also have no effect and positive effect on coffee exports in Indonesia.The suggestion in this study is that it is expected that the government needs to emphasize the Amount of Coffee Production in Indonesia, this is done so that Exports and The Amount of Coffee Production are balanced with each other and increase state income.

Abstract

The rising levels of heavy metal pollution in water bodies present major environmental and public health issues. Conventional methods for remediation often come with high costs and produce secondary waste, which can pose additional environmental risks. As an alternative, chitosan—a natural, biopolymer derived from chitin—has gained attention as a promising biosorbent for heavy metal removal. Its advantages include biocompatibility, biodegradability, and a strong ability to bind metal ions effectively. This review explores chitosan’s capacity to adsorb various heavy metals and examines its practical applications in biosorption technology. Key factors that impact its adsorption efficiency, such as solution pH, metal concentration, and contact time, are discussed. Additionally, structural modifications to enhance chitosan’s performance, including cross-linking and nanoparticle incorporation, are analyzed to highlight improvements in adsorption efficiency. By assessing these elements, this review aims to offer a comprehensive perspective on the role of chitosan in environmental management, particularly for treating heavy metal contamination in wastewater. The findings underscore chitosan's potential as a sustainable solution in pollution control, emphasizing its advantages over traditional methods and its capacity to contribute to cleaner water resources.

Pada pengabdian yang dilaksanakan oleh mahasiswa KKN UIN Sumatera Utara Medan Kelompok 147 di Desa pegajahan mulai dari tanggal 18 July–18 Agustus 2022 ini bertujuan untuk memberikan edukasi tentang pemasaran secara online kepada pemilik usaha gula merah berbahan dasar nira sawit untuk memperluas jaringan pemasaran agar dapat membantu meningkatkan pendapatan masyarakat di Desa Pegajahan. Berdasarkan hasil observasi yang dilakukan saat melaksanakan pengabdian masyarakat ditemukan bahwa jaringan pemasaran hanya sebatas agen atau bergantung pada pengepul saja. Oleh sebab itu pengabdian dilaksanakan dengan cara memberikan sosialisasi atau penyuluhan kepada pengusaha gula merah agar dapat memperluas jaringan pemasaran yang nantinya meningkatkan penjualan, hasil produksi dan keuntungan sehingga dapat membuka lapangan pekerjaan bagi masyarakat. Metode pengabdian yang dilakukan yatu observasi dan wawancara, identifikasi masalah, pelaksanaan sosialisasi, penerapan, evaluasi dan hasil akhir.

Abstract

Latar Belakang Masalah: Penelitian ini dilatarbelakangi oleh masih seringnya terjadi kasus tenggelam di kolam renang akibat kurangnya keterampilan dan pengetahuan renang. Media audio visual dan alat bantu diyakini dapat meningkatkan kemampuan tersebut. Tujuan penelitian ini adalah mengembangkan media pembelajaran audio visual renang gaya dada untuk meningkatkan hasil belajar peserta didik. Metode: Metode yang digunakan adalah penelitian dan pengembangan (R&D) dengan model ADDIE. Sampel diperoleh melalui cluster random sampling menggunakan aplikasi Google Spin, sehingga terpilih kelas VIII-A dengan jumlah 31 siswa. Instrumen pengetahuan berupa 12 soal valid, sedangkan keterampilan dinilai oleh 3 rater bersertifikat dengan konsistensi baik. Data dianalisis secara deskriptif menggunakan skala Likert (1–4), uji normalitas Shapiro-Wilk, serta uji beda Paired T-Test dengan taraf signifikansi 0,05 melalui SPSS. Hasil: Hasil penelitian menunjukkan media pembelajaran yang dikembangkan dinyatakan sangat layak dari aspek materi (99%), media (98%), dan praktisi (99%). Hasil belajar siswa juga mengalami peningkatan signifikan. Pada aspek pengetahuan, nilai pretest 3,94 meningkat menjadi 9,84 (149%, p < 0,001). Pada aspek keterampilan, nilai pretest 31,29 meningkat menjadi 60,10 (92%, p < 0,001). Kesimpulan: Kesimpulan penelitian menyatakan peningkatan pengetahuan lebih tinggi dibanding keterampilan, kemungkinan karena durasi latihan fisik lebih singkat dibanding paparan informasi kognitif melalui media. Guru PJOK disarankan menayangkan video terstruktur berdurasi ≤ 10 menit sebelum praktik, dilaksanakan minimal empat pertemuan, dengan penggunaan swimboard serta rubrik penilaian baku dan penilai ganda.

Abstract

Food waste remains a major challenge in school meal programs, as it not only causes economic losses but also leads to resource inefficiency, and reduced nutritional benefits. This study aims to analyze differences in food waste amounts across free nutritious meal programs at the elementary, middle, and high school levels, estimate nutrient loss, and identify related factors of food waste among students in East Aceh Regency. A cross-sectional design was employed involving 106 students purposively selected from three schools participating in the free nutritious meal programs. Data were collected using a weighing method over a 10-day menu cycle, anthropometric measurements, structured interviews on student characteristics, and food preferences. Data were analyzed using the Kruskal-Wallis test, Pearson and Spearman correlations, and linear regression. The results showed that the average food waste was 24,3% of the served portion, with the highest amount in middle school (29,8%) and the lowest in high school (16,5%). The largest proportion of waste came from staple foods, vegetables, and plant-based side dishes. Nutrient loss due to food waste was equivalent to 12 complete lunch portions for a child per year. Factors significantly associated with food waste were age, gender, BMI-for-age, pocket money, and menu variety (p<0,05). Older students, males, who perceived the menu as more varied, tended to waste less food. These findings highlight the importance of portion adjustment, appropriate serving times, diversified menus, and nutrition education to reduce food waste and optimize the benefits of the Free Nutritious Meal program
