Abstract

This study aims to determine the effect of the concentration of rice husk charcoal and cow manure on the growth of Dayak onions (Eleutherine americana Merr.) And produce Student Worksheets for class XII SMA. This research was conducted in Jayapura Village, Siak Regency, in October-December 2019. This study used an experimental method with a completely randomized factorial design consisting of 2 treatments using a combination of rice husk charcoal and cow manure and each treatment was repeated as much 3 times. The parameters of this study were leaf length, number of leaves, number of tillers, leaf wet weight, and tuber wet weight. The design of LKPD development refers to the stages of the Problem Based Learning model which are simplified into the Analyze and Design stages. The results showed that the combination of rice husk charcoal and cow manure can increase the growth of Dayak onions significantly affected at a dose of 90 gr/tan (S2K2) with the best treatment on each parameter observed. The results obtained will be used as a development material for the growth and development of Class XII SMA in KD 3.1 and 4.1. The results of the design of learning tools in the form of Syllabus, RPP and LKPD.

Abstract

The aims to determine the effect of chitosan concentration and smoking time on the quality of smoked catfish (Pangasius sp.) and produce Student Worksheet design. This research was divided into two step, there is experimental step and the Student Worksheet design. At the experimental step, used a factorial Completely Randomized Design (CRD). Factor I is the concentration of chitosan, and factor II is duration of smoking time. This study consisted of 12 treatments with 3 replications so that there were 36 experimental units. Parameters observed were protein content, fat content, water content and organoleptic on appearance, scent, taste and texture. The results showed that the effect of chitosan concentration and smoking time had an effect on treated with 3% chitosan and 3 days of smoking showed the best results, with the total protein content was 35.89%, fat content was 29.72% and water content was 15.27%. Meanwhile, the organoleptic test results of smoked catfish on the aspects of appearance, scent, taste and texture, the best treatment was also found in smoked catfish with 3% chitosan treatment and 3 days of smoking time. The results can be used as a student worksheet design on Food Additives material for class XI high school.

Abstract

Vegetasi bawah adalah lapisan penutup tanah yang terdiri dari herba, perdu atau perdu liana dan paku-pakuan. Keanekaragaman vegetasi bagian bawah dapat dimanfaatkan sebagai bahan pengayaan materi keanekaragaman hayati pada tingkat spesies. Keanekaragaman hayati merupakan ilmu dasar yang sudah ada dibidang ekologi. Materi tentang keanekaragaman hayati ini telah dijadikan sebagai materi utama dalam kurikulum 2013. Keanekaragaman hayati disajikan khususnya pada materi untuk siswa kelas X SMA yaitu KD 3.2 menganalisis data hasil pengamatan tentang berbagai tingkat keanekaragaman hayati (gen, spesies dan ekosistem) di Indonesia seta ancaman dan pelestariannya. Penelitian ini dilaksanakan di Laboratorium Alam Pendidikan Biologi Universitas Riau, perancangan buku saku dilakukan pada bulan September 2021. KD yang cocok untuk diintegrasikan dengan hasil penelitian tumbuhan bawah di Laboratorium Alam Pendidikan Biologi adalah KD 3.2 menganalisis data hasil pengamatan tentang berbagai tingkat keanekaragaman hayati (gen, spesies dan ekosistem) di Indonesia serta ancaman dan konservasinya. Perancangan buku saku ini disesuaikan dengan pendekatan discovery learning. Buku saku tumbuhan bawah yang telah dibuat dapat digunakan sebagai media pembelajaran materi keanekaragaman hayati di SMA Biologi kelas X dari tahap analisis, desain dan pengembangan.
