Abstract

Kompos merupakan pupuk organik yang mudah dan murah dengan memanfaatkan limbah sisa bahan organik. Kompos mempunyai sifat lama tersedia bagi tanah dan tumbuhan,namun bersifat aman bagi lingkungan. Karena bahan organik berupa kompos dapat memperbaiki sifat kimia, fisik dan biologi tanah. Pada penelitian ini memanfaatkan limbah kulit pisang goroho. Sebagai bioaktivator digunakan BAL dalam bentuk kultur kering. Penelitian ini menggunakan keragaman dosis kultur kering BAL yang terdiri dari 3 taraf yaitu kontrol, 20%, 30%, dan 40% dari bobot bahan organik. Data yang dihasilkan kemudian dilakukan uji analisis kandungan ketersedian nitrogen dan C-Organik. Berdasarkan hasil peneliian di peroleh ketersedian Nitrogen yang sesuai dengan standar SNI pupuk kompos, sedangkan untuk kadar C-Organiknya rata-rata belum sesuai dengan dengan standar SNI

Abstract

Virgin Coconut Oil contains medium chain fatty acids that are easily digested and oxidized by the body so as to prevent accumulation in the body. This research will try to produce virgin coconut oil / VCO by fermentation and using various variations of the concentration of BAL dry culture starter. The use of BAL dry culture has several advantages including being able to be stored for a long time in cold temperatures, easily applied and cost efficiency. The purpose of this study was to determine the percentage of Free Fatty Acid (FFA) and yield produced in the fermentation process of virgin coconut oil. Because the lower the FFA value produced the higher the quality of the oil produced The parameters observed in this study are the percentage of Free Fatty Acid (FFA), yield of virgin coconut oil (VCO), and water content. This study used a complete randomized design with 1 factor, namely the concentration of BAL dry culture, with the following research treatments: A1 = 5 gram of BAL dry culture; A2 = 10 gram of BAL dry culture; A3 = 15 gram of BAL dry culture; A4 = 20 gram of BAL dry culture. From the results of the study it can be concluded that the best treatment of water content is in treatment A3 which is 0.1463%. The best treatment yield was in treatment A1, which was 13.336%.

Abstract

Tujuan penelitian ini adalah mengetahui pengaruh pH dan warna terhadap penyimpanan selai papaya Kalifornia (Carica Papaya L). Uji pH dilakukan dengan mengkalibrasinya dengan buffer pH 4 dan buffer pH 7 lalu dikeringkan dengan tissue. Kemudian instrument tersebut dicelupkan sampai diperoleh keadaan stabil selama 15 sampai 30 menit. Pengujian warna ini menggunakan alat pendeteksi warna yaitu Colorimeter AMT-501. Dengan menggunakan alat ini kita dapat mengidentifikasi perbedaan warna menggunakan koordinat L*a*b*. Rata-rata kadar pH pepaya kalifornia berturut-turut 5.15, 5.12, 5.04, 5.02, 4.79, 4.78, 4.69 dan 4.61. Adapun nilai ΔE dari hari 1hingga 6 adalah 1.81, 1.92, 1.22, 2.40, 2.82, 2.91, 3.16.

Abstract

This study aims to analyze the improvement of students' learning outcomes in economic activity material through the use of Crossword Labs learning media in class X.11 SMAN 3 Pekanbaru. The background of the study is based on the low learning outcomes of students in economics learning which is considered difficult and less interesting. To overcome this, the researcher applied the Cooperative Learning model combined with Crossword Labs media to create an interactive and enjoyable learning atmosphere. This study uses the Classroom Action Research (CAR) method of the Kemmis and McTaggart model, which is carried out in two cycles through the stages of planning, action, observation, and reflection. The subjects of the study were 36 students of class X.11 who were selected through saturated sampling techniques. Data were analyzed quantitatively using a difference test (paired sample t-test) to determine the effectiveness of the learning media. The results showed a significant increase in learning outcomes, with most students experiencing an increase in grades. These findings indicate that Crossword Labs media is effective in improving students' learning outcomes in Economics subjects.
