Abstract

Tomatoes are essential for Indonesians because they have high economic and nutritional value. In addition, as population growth increases, the demand for tomatoes also increases. Based on this, it is essential to research to predict the future development of tomato crop production. The research in this paper uses a dataset of tomato plant production in Indonesia, which is spread across 34 provinces in the last seven years, namely from 2015 to 2021), which is sourced from the Indonesian Central Bureau of Statistics and the District/City Agriculture Service of each Province. The algorithm proposed in this study is the Fletcher-Reeves Conjugate Gradient Algorithm which will be processed with the help of Matlab2011b. Research analysis with three network architectural models: 5-7-1, 5-13-1, and 5-17-1. Based on a network comparison of the three architectural models, the best result is the 5-17-1 model because the MSE value is the smallest compared to the other two models, namely 0.0009915 compared to 0.0010851 and 0.0049764, as well as the highest level of accuracy, namely by 94% versus 91% and 88%. Therefore the 5-17-1 model is used to predict the yield of tomato production in Indonesia for the future (2022 and 2023). Based on the prediction results at the end of 2022 and 2023, there are 18 provinces where tomato crop production has the potential to increase, although not too significantly. The prediction of tomato production using the Fletcher-Reeves algorithm is quite good because it produces a small error rate and high accuracy.

Abstract

Research on coffee exports to main destination countries is important because it provides an in-depth understanding of the markets that are the main focus. This allows governments and businesses to allocate resources efficiently and design appropriate marketing strategies. In addition, this research provides a strong basis for the government in formulating coffee export policies. By monitoring the development of coffee exports to main destination countries, Indonesia can be better prepared to face changes in global market demand and take appropriate steps in responding to market dynamics. . This research will use the Conjugate Gradient Fletcher-Reeves algorithm, which is one of the algorithms of Artificial Neural Networks. The research was analyzed using 3 architectural models, including: 5-5-1, 5-10-1, and 5-15-1. As a result, the 5-5-1 model was selected as the best model, with the highest accuracy of 94% and the lowest MSE of 0.00500142. Higher than the accuracy of the 5-10-1 model which is only 83% with MSE 0.05058359, and 78% accuracy with MSE 0.01975643 on the 5-15-1 model. Based on the estimation results regarding the development of coffee exports according to main destination countries using the 5-5-1 model, the conclusion that can be drawn is that there will likely be a decline in the level of coffee exports to main destination countries in 2024.

Abstract

Penelitian ini dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas Asahan, Kelurahan Kisaran Naga, Kecamatan Kisaran Timur, Kabupaten Asahan, Provinsi Sumatera Utara dengan topografi ketinggian 23 mdpl dengan suhu sekitar 20oC-30oC dan kelembaban mencapai 90%. penelitian ini dilaksanakan Januari sampai April 2022. Penelitian ini disusun berdasarkan Rancangan Acak Kelompok (RAK) faktorial dengan 2 faktor perlakuan dan 3 ulangan. Faktor pertama adalah perlakuan Intensitas Cahaya (I) dengan 3 taraf yaitu I1 = 75% intensitas cahaya, I2 = 50% intensitas cahaya, I3 = 25% intensitas cahaya. Faktor kedua adalah perlakuan Pupuk Kandang Sapi (S) dengan 4 taraf yaitu S0 = 0 ton/ha Pupuk Kandang Sapi (kontrol), S1 = 5 ton/ha Pupuk Kandang Sapi (0,5 kg/plot), S2 = 10 ton/ha Pupuk Kandang Sapi

Abstract

Abstract: Wastewater from fish farming is useless to fish breeders and the community in general. The contents of wastewater include specific compounds such as ammonia, which has benefits as a nutrient source for plants. However, this information is restricted between fish breeders, including the Mekar Jaya fish breeders. The goal of this activity is to provide additional knowledge and broaden understanding of the benefits of wastewater from fish farming activities in supporting plant growth. The stages of this activity are the preparation stage, the implementation stage, and the evaluation. The results of this community service activity have a positive impact, namely that partners are using wastewater from fish farming to irrigate plants. The plants irrigated with wastewater from fish farming become more fertile. The community service activity concludes that the socialization related to the utilization of wastewater from fish farming provides positive benefits for partners, as evidenced by the increased productivity of plants and the reduced dependence on chemical fertilizers. Keyword: fish; plant; pond; wastewater. Abstrak: Air limbah yang berasal dari pemeliharaan ikan kurang dimanfaatkan oleh pembudidaya ikan maupun masyarakat pada umumnya. Kandungan dari air limbah adalah senyawa-senyawa tertentu seperti amonia yang memiliki manfaat sebagai sumber nutrisi bagi tanaman. Akan tetapi, informasi ini masih minim di kalangan pembudidaya ikan, salah satunya pembudidaya ikan Mekar Jaya. Tujuan dari kegiatan ini adalah untuk  memberikan pengetahuan tambahan dan memperluas wawasan tentang manfaat air limbah dari kegiatan budidaya ikan dalam mendukung pertumbuhan tanaman. Tahapan dari kegiatan ini yaitu tahapan persiapan, tahapan pelaksanaan dan evaluasi. Hasil kegiatan pengabdian kepada masyarakat ini memberikan dampak positif yaitu mitra menggunakan air limbah dari pemeliharaan ikan untuk menyirami tanaman. Dan tanaman yang disiram menggunakan air limbah pemeliharaan ikan menjadi lebih subur. Simpulan dari kegiatan pengabdian kepada masyarakat yaitu kegiatan sosialisasi terkait pemanfaatan air limbah dari pemeliharaan ikan memberikan manfaat positif bagi mitra, ditandai dengan meningkatnya produktivitas tanaman serta berkurangnya ketergantungan terhadap pupuk kimia. Kata kunci: ikan; tanaman; kolam; air limbah.
