Abstract

Abstract: The purpose of this study was to improve the results and learning process of Genetic subjects in the Biology Education Study Program through lesson study (LS). The research type is descriptive, the sampling technique used purposive. The study sample used 40 students in the sixth semester of class a Biology Education Study Program, Faculty of Education, University of Mataram in academic year 2017/2018. The research data collection technique used observation, documentation, and tests. Data on student learning outcomes and LS-based learning processes were analyzed descriptively. LS implementation in this study consisted of four cycles and each cycle consisted of three stages, namely: planning, implementation, and reflection. Classically the average value of students' cognitive achievement is 82.1% in cycle I and II while in cycle III and IV it increases to 82.67%. Data from LS implementation observation results obtained an average value of 91.63%. The conclusion of this study is the application of LS learning can improve student achievement and learning processes on Genetic subjects in the Biology Education Study Program. It is recommended to other researchers to conduct similar follow-up research in broader research areas, more samples, use more complex research designs, and use more subjects so that more optimal results can be found. Keywords: Lessons Study; learning; genetics; learning achievements; collaborative

Abstract

Pengabdian pada masyarakat ini telah dilaksanakan di Desa Jatisela Kecamatan Gunung Sari Kabupaten Lombok Barat Propinsi Nusa Tenggara Barat. Sebagian masyarakat Desa Jatisela yang bermatapencaharian sebagai petani, kuhusnya yang berdomisili di Dusun Ireng Daye memiliki usaha sampingan yaitu beternak sapi, kuda dan kambing. Mereka membentuk kelompok ternak yang disebut Kelompok Ternak Patuh Angen. Kegiatan peternakan sapi yang dilakukan oleh Kelompok Ternak Patuh Angen menghasilkan limbah berupa kotoran ternak dan sisa makanan ternak. Peternak sapi di Dusun Ireng Daye belum menemukan alternatif pemecahan masalah limbah peternakan sapi yang ada di sekitar tempat tinggal mereka. Pengolahan limbah peternakan sapi menjadi pupuk organik merupakan alternatif pemecahan masalah yang dapat diterapkan untuk mengatasi permasalahan yang mereka hadapi. Pupuk organik yang dihasilkan dapat dijadikan pupuk untuk meningkatkan hasil panen tanaman. Adapun tahapan kerja pengolahan limbah peternakan sapi menjadi bokashi dan pemanfatannya pada lahan pertanian adalah sebagai berikut: (1) sosialisasi kegiatan, (2) penyampaian materi tentang kebersihan lingkungan, cara pembuatan bokashi dan manfaat bokashi untuk pertumbuhan tanaman, (3) pembuatan bokashi, (3) penggunaan bokashi pada lahan pertanian.  Metotode yang digunakan adalah metode ceramah, diskusi, pelatihan dan pendampingan. Dalam pelaksanaan kegiatan ini nampak bahwa masyarakat yang menjadi mitra kegiatan telaah mengikuti kegiatan dengan baik mulai dari sosialisasi kegiatan sampai pada kegiatan terakhir pelaksanaan pengabdian. Hal ini dapat dilihat dari banyaknya pertanyaan yang diajukan peserta yang terkait dengan materi yang disampaikan tim pelaksana pada saat diskusi. Selain itu pada saat praktek pembuatan bokashi semua peserta ikut bekerja secara aktif sehingga kegiatan paraktek pembuatan bokashi dapat berjalan lancer. Kata Kunci: Pendampingan masyarakat; pengelolaan limbah; peternakan sapi; pertumbuhan tanaman.

Abstract

The present work aims to study the effect of pineapple fruit extracts on the quality of Chemical and microbiological - rabbitfish sauce products. Utilizing pineapple extract can speed up the fermentation process because pineapple extract contains bromelain enzymes that will break down rabbitfish’s protein, carbohydrate, and fat molecules into simpler molecules. The research method applied involved experimental laboratory procedures. This study used a completely randomized design. The variables observed were protein, water content, acidity (pH), total microbe, total lactic acid bacteria, Escherichia coli, Staphylococcus, and taste values. The pineapple extracts and fermentation length affected sauce product quality significantly. Pineapple extracts of 15% and 12-day fermentations produced the best sauce quality, consisting of 14.18% protein content, 73.55% moisture content, and a pH of 5.26. Besides, other parameters observed were total microbes 7.8 x 104 CFU/g, total lactic acid bacteria 1, 0 x 102 CFU/g, E. coli, and Staphylococcus sp. (negative), taste value was 3.46, but consumers did not like it so much. However, these results have met the Indonesian National Standards for the product and are safe for human consumption.
