STABILITAS KANDUNGAN AMILOSA BERAS BEBERAPA VARITAS PADI SAWAH DI SUMATERA BARAT
No full textAmylose content of rice is one of the variables that determine the quality of rice. Although Solok considered a first-class rice-producing areas inWest Sumatra, but a stable varieties will produce amylose content is relatively similar across all planting sites, so it can be cultivated in various regions. The study was conducted at 3 locations lowland rice production centers inWest Sumaterathat is Solok, Bukittiggi and Pariaman. The research design used at each location is randomized block design with 3 replications. The treatment consisted of 5 varieties of rice that is Cisokan, Anak daro, Randah-kuniang, Kuriak kusuik and Saratuih hari. The results showed that the five varieties tested showed a stable amylose content.Key words: stability, amylose, rice, west sumater
EXPLORASI DAN MUTU BERAS GENOTIP PADI MERAH DI KABUPATEN PASAMAN BARAT SUMATERA BARAT
No full textThe purpose of this study was to determine the nutrient content based on the phenotype of red rice in West Sumatra West Pasaman. The study was conducted in the West Pasaman by doing a survey to determine and collect the red rice in the area. Limited access to isolated areas growing regions in the rice collection was also done by buying rice from the traditional market vendors West Pasaman. Analysis of the nutrient content in the form of protein and amylose conducted in the Laboratory of Chemistry Department of Chemistry, State University of Padang. The results showed that in the West Pasaman found 5 red paddy rice genotypes. Amylose content ranged from 27.16% to 40.13% Island Manggis until at Nabara. Protein content ranged from 5.93% to 8.72 on the genotype Nabara Cimarisik genotype. Based on these results it can be concluded that the Dolok Nabara (8.25%) and Cimarisik (8.72%) developed considering the potential for relatively higher protein content than rice genotypes grown in West Sumatra. In conclusion, the amylose content of the five genotypes were high.Key words:  explorasi, genotip, quality rice, red rice, west pasama
Biology Teachers' Readiness in State High Schools in West Sumatra Facing Learning in the Era of the Industrial Revolution 4.0 on Aspects of Communication Skills

Full text linkPeningkatan kadar klorofil dapat dipengaruhu oleh kemampuan Trichoderma asperellum dalam meningkatkan penyerapan nutrisi, khususnya nitrogen sebagai komponen penting dalam sintesis klorofil. Penelitian bertujuan menganalisis pengaruh frekuensi formula Trichoderma asperellum terhadap kadar klorofil. Penelitian dengan metode eksperimental dengan menggunakan Rancangan Acak Lengkap (RAL), dengan penambahan ecoenzyme pada konsentrasi 0% dan 60% yang terdiri dari 5 perlakuan dan 5 ulangan. Hasil menunjukkan pada klorofil a nilai tertinggi 6.8260 mg/L dan terendah 5.7620 mg/L. Hal ini, Trichoderma asperellum tidak berpengaruh signifikan. Pada klorofil b tercatat nilai tertinggi 8.7280 mg/L dengan nilai paling rendah 6.6500 mg/L menunjukkan adanya perbedaan yang signifikan. Sedangkan pada klorofil total mencatat nilai tertinggi 15.328 mg/L dan terendah 12.458 mg/L. menunjukkan bahwa tidak ada pengaruh signifikan diantara perlakuan
Based Module Development PBL (Problem Based Learning) in the Matter Excretion Systems for Class XI MIPA SMAN 3 Kerinci
No full textStudent difficulties in understanding the material of the respiratory system and the excretory system for memorizing the material when the material is very close to everyday life, to the existence of modules that can guide students to discover concepts with issues close to the everyday life. Modules that are used in schools has not assist students in finding the concept directly to the material learned. The aim to be achieved from this development effort is to produce a module-basedProblem Based Learning on the material of the respiratory system and the excretory system for high school students of class XI. Research development Plomp is using a model consisting of three stages, namely a preliminary investigation, prototyping, and evaluation. Subject penilitian is a class XI student of SMAN 3 Kerinci. Validation is done by experts in biology education, education technology and Indonesian. Practicality module seen from the results of the questionnaire filling practicalities by students and teachers as well as conducting interviews with students. seen the effectiveness of student competence and the data were analyzed by descriptive. The results showed that the module-based Problem Based Learningobtain very valid category. Category practicalities of response is very practical teacher and student response practicalities category very practical. This module has also been effective in terms of student competence. In this case increase student competence more than the specified minimum attainment. Based on these results, we can conclude that Problem Based Learning modules based on the material excretion system for high school students of class XI can be declared valid, practical and effective.Keywords: Module, Problem Based Learning, Valid, Practical, Effectiv
