Abstract

The Regional Plantation Company (PDP) Kahyangan Jember as a producer of Robusta coffee experienced a decline in profits. As a result of not fertilizing coffee plants, the production of PDP Kahyangan Jember coffee has decreased drastically. So far, Gunung Pasang PDP Kahyangan Jember gardens only use chemical fertilizers and never use organic materials to maintain soil fertility. The use of litter buried in the rorak around the coffee plant canopy is an alternative to increase soil organic matter and plant nutrients. Decomposer technology from cow rumen can be applied to accelerate the decomposition process of plant litter which can increase soil organic matter while providing nutrients or nutrients needed by plants. The objectives of this service are: (i) accelerating the process of decomposition and mineralization of plant litter; (ii) increase soil organic carbon and provide plant nutrients; (iii) improve growth and increase coffee crop production. The method of service is carried out, among others, namely: (i) counseling in the form of the importance of increasing soil organic matter around the coffee plant canopy and the role of decomposers from cow rumen to accelerate the process of decomposition and mineralization of plant litter as a provider of plant nutrients); (ii) training in the practice of making decomposers from cow rumen; (iii) apply the decomposer technology from cow's rumen to plant litter and evaluate the results of the application of decomposer technology from cow's rumen to plant litter. Through discussions and questions and answers between the Telecommunications Rumen Decomposer Technology Development Team at the State Polytechnic of Jember with the PDP Kahyangan Management Team and the Management of Gunung Pasang Jember Gardens, it was concluded that the application of cow rumen decomposer technology has been running smoothly and quite successfully and can be applied in plantation areas

Abstract

This research purpose to increase students' self-efficacy in mathematics subjects with flat material through the problem based learning model at SDN Pisangan Timur 05 Pagi Jakarta Timur. This Classroom Action Research was carried out in 3 cycles, where each cycle contained 4 stages including: a.) Planning, b.) Acting, c.) Observing, and d.) Reflecting. The research results show that there is an increase in learning outcomes which can be seen from the implementation of research in each cycle. Self efficacy can be seen from the score obtained before the class average was 49.94% in the low category, in cycle I it increased to 69.2% in the medium category, and in cycle II it increased to 85.04% in the very high category. The increase in student self-efficacy can be seen from the majority of students being able to solve problems given by the teacher through teaching aids, students do not hesitate to work on problems with group members, students are able to think independently when solving mathematical problems, students are confident in the solution and dare to give opinions regarding differences problem solving, students have the ability and confidence in the correctness of concepts, principles of mathematical procedures regarding the problem being solved.

Abstract

Pupuk merupakan bahan mengandung unsur hara yang diberikan ke media tanam untuk memenuhi kebutuhan hara untuk tanaman. Pupuk hayati cair merek "Basiscrop" merupakan salah satu produk pupuk hayati cair yang diproduksi oleh CV. Basiscrop Indonesia. Tujuan dari penelitian ini untuk mengetahui substitusi pupuk hayati cair "Basiscrop" dengan NPK terhadap pertumbuhan dan hasil tanaman jagung manis (Zea mays L. Saccharata) varietas Secada F1. Pengujian dilakukan pada bulan Januari hingga Mei 2025 di Lahan Percobaan Kimia Tanah dan Nutrisi Tanaman, Fakultas Pertanian Universitas Padjadjaran, Jatinangor. Penelitian ini menggunakan rancangan penelitian Rancangan Acak Kelompok (RAK) yang terdiri atas delapan perlakuan, yaitu satu kontrol (tanpa pupuk), satu perlakuan pupuk rekomendasi, satu perlakuan dengan 3/4 dosis pupuk rekomendasi, dan enam kombinasi dosis pupuk hayati cair "Basiscrop" dengan pupuk anorganik. Seluruh perlakuan diberikan ulangan sebanyak tiga kali. Hasil penelitian pada 8 perlakuan memberikan hasil pertumbuhan dan komponen hasil terbaik pada perlakuan 1 dosis N (350 kg/ha), 1 dosis P (100 kg/ha), 1 dosis K (50 kg/ha), dan 1 dosis pupuk hayati cair "Basiscrop" (30 kg/ha).
