Penelitian ini bertujuan untuk mengetahui korelasi keterlaksanaan pembelajaran biologi dengan hasil belajar siswa menggunakan model pembelajaran kooperatif tipe jigsaw pada siswa kelas XII di SMA Hang Tuah 3 Mataram. Penelitian ini merupakan penelitian deskriptif kuantitatif yang dilakukan tiga pertemuan. Instrumen yang digunakan adalah lembar observasi keterlaksanaan pembelajaran dan lembar soal. Hasil penelitian menunjukkan bahwa pembelajaran biologi dengan menerapkan pembelajaran kooperatif tipe jigsaw terdapat hubungan positif antara keterlaksanaan pembelajaran biologi dengan hasil belajar siswa menggunakan model pembelajaran kooperatif tipe jigsaw (Spearman’s rho) = (+) 0,998*, sig = (0,39 > 0,05). The Correlation of Biology Learning Implementation with Student Learning Outcomes Using the Jigsaw Type Cooperative Learning Model This study aims to determine the correlation between the implementation of biology learning with student learning outcomes using the jigsaw-type cooperative learning model in class XII students at Hang Tuah 3 High School Mataram. This research is a quantitative descriptive study conducted in three meetings. The instruments used were observation sheets on the implementation of learning and question sheets. The results showed that learning biology by applying jigsaw type cooperative learning there is a positive relationship between the implementation of biology learning and student learning outcomes using the jigsaw type cooperative learning model (Spearman's rho) = (+) 0.998*, sig = (0.39 > 0.05.
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.
Community service is an activity that realizes and improves the quality of community knowledge in helping the problems experienced by the community in the community. Through the Thematic Real Work Lecture (KKNT) program based on community service, this activity is to increase students' sense of solidarity with the existing conditions of the community. The use of land with hydroponic cultivation is an alternative that can be done by utilizing minimal yard land and being able to use used goods. Farming with hydroponics is very environmentally friendly in addition to not using pesticides, also the production can be used alone or as an economic source of household income. In addition, the outputs obtainedare n: (1) Improvement of superior quality of resources; (2) improving household economic resources; (3) Encourage the progress of the village. On the other hand, to ensure the discipline and participation of KKNT student participants and the community, by seeing the success in the form of outputs produced
Pengaruh Aplikasi Pupuk kandang Sapi dan Bokashi Sampah Kota Terhadap Pertumbuhan dan Produksi Tanaman Mentimun (Cucumis sativus L). Penelitian ini dilaksanakan di kebun percobaan Universitas Asahan, jalan jend. Ahmad Yani, Kecamatan Kisaran Timur Kabupaten Asahan dengan topogafi dan ketinggian tempat ± 20 m dpl. dilakukan pada bulan Februari s/d April tahun 2021. Penelitian ini disusun berdasarkan Rancangan Acak Kelompok (RAK) Faktorial dengan 2 faktor perlakuan dan 3 ulangan. Faktor pertama adalah aplikasi pupuk kandang sapi dengan 4 taraf yaitu : K0 = 0 kg plot-1, K1 = 1 kg plot-1,K2 = 2 kg plot-1 dan K3 = 3 kg plot-1. Faktor kedua adalah aplikasi bokashi sampah kota, dengan 3 taraf yaitu S0 = 0 kg plot-1, S1 = 1 kg plot-1dan S2 = 2 kg plot-1. Hasil penelitian menunjukkan bahwa aplikasi pupuk kandang sapi menunjukkan pengaruh nyata terhadap diameter buah, panjang buah, produksi tanaman per sample, produksi tanaman per plot dengan perlakuan terbaik yaitu 3 kg plot-1. Aplikasi bokashi sampah kota tidak berpengaruh nyata terhadap seluruh parameter amatan tanaman mentimun. Interaksi aplikasi pupuk kandang sapi dan bokashi sampah kota tidak berpengaruh nyata terhadap seluruh parameter amatan tanaman mentimun
