Abstract

Mangroves (Rhizophora apiculata) are one of the plants that grow in mangrove forests. The significant degradation of mangrove forests in Indonesia requires effective and efficient rehabilitation efforts. Efforts to provide superior seeds in a short time and in large quantities, one of which is through tissue culture. ZPT (Growth Regulator) Kinetin and IAA in balance can stimulate the morphogenesis process in the explant. This study used a 4×4 factorial randomized complete (RAL) design with 3 replications. The first factor is the concentration of kinetin. 0 mg/L, 1 mg/L, 3 mg/L, and 5 mg/L. The second factor is IAA concentrations of 0 mg/L, 0.5 mg/L, 1 mg/L, and 1.5 mg/L. The parameters observed were explant growth time, explant growth percentage, and bud height. The results showed an interaction with the plant growth time factor, and the best plant growth rate was achieved using the kinetin treatment of 5 mg/L and the IAA treatment of 1.5 mg/L, while the best shoot height factor was found in the kinetin treatment of 5 mg/L. l and IAA 1 mg/L treatment concentrate.

Abstract

Diagnostic assessment is a crucial step in the differentiated learning process as an implementation of the Merdeka curriculum. This study aimed to develop a diagnostic assessment instrument that can identify students' learning styles and critical thinking skills, especially in the Cell and Bioprocess material, in the context of implementing the Independent Curriculum. This study uses the Research and Development (R&D) method with the Borg and Gall development model. The subjects of the study were 35 grade X students of SMA Negeri 8 Pekanbaru who were selected randomly. Data analysis was carried out using the Rasch model with Winstep. The results of the study showed that the critical thinking diagnostic instrument had high validity and good reliability, while the learning style instrument had low reliability and needed further improvement. Several learning style assessment items were considered invalid and had to be adjusted or discarded. This diagnostic assessment instrument is expected to help teachers develop more effective learning strategies that are in accordance with the individual needs of students, so that it can improve the quality of learning, especially in understanding the Cell and Bioprocess material.

Abstract

ABSTRAK Bekasam merupakan proses pengawetan dengan teknik fermentasi menggunakan ikan, beras sebagai sumber karbohidrat, dan garam yang dimasukkan ke dalam toples tertutup rapat dan disimpan selama beberapa hari. Tujuan penelitian ini adalah untuk mengetahui pengaruh jenis-jenis sumber karbohidrat dari perbagai perlakuan beras terhadap mutu ikan sepat toakang (Helestoma temminckii) dari mutu kimia dan organoleptik. Jenis penelitian ini merupakan percobaan dengan Rancangan Acak Lengkap (RAL) menggunakan konsentrasi sumber karbohidrat sebanyak 50% dari berat ikan, yaitu beras, nasi karak, nasi panggang, dan tepung beras. Jumlah perlakuan yang digunkan yaitu 4 perlakuan (beras sanggrai, nasi, kerak dan tepung beras) dengan jumlah pengulangan masing-masing 3 kali. Parameter yang diamati adalah kandungan protein, kandungan lemak, pH dan kadar air. Penambahan berbagai jenis sumber karbohidrat berpengaruh signifikan terhadap kualitas ikan sepat bekas toakang dari kualitas kimia dan organoleptik dengan hasil terbaik yaitu perlakuan nasi sangrai dengan kandungan protein 16,12%, kadar lemak 6,86%, kadar air 68,83%, dari segi warna dan aroma,  Yaitu warna yang baik dan merata secara optimal serta aroma khas bekasam dan aroma yang sangat tajam. Kandungan nilai mutu ikan sepat toakang bekas telah memenuhi kriteria TKPI dan dapat dikonsumsi. Kata kunci: jenis sumber karbohidrat, bekasam, kualitas, ikan sepat toakang ABSTRACT Bekasam is a preservation process with fermentation techniques using fish, rice as a source of carbohydrates, and salt which is put in a tightly closed jar and stored for several days. The purpose of this study was to determine how the influence of the type of carbohydrate source on the quality of the former toakang sepat fish (Helestoma temminckii) from chemical and organoleptic quality. This type of research is an experiment with a Complete Randomized Design (RAL) using a concentration of carbohydrate sources as much as 50% of fish weight, namely rice, rice karak, roasted rice, and rice flour. The total treatment obtained was 4 treatments with the number of repetitions 3 times each. The parameters observed were protein content, fat content, pH, and water content. The addition of various types of carbohydrate sources has a significant effect on the quality of the former toakang sepat fish from chemical and organoleptic quality with the best results, namely the treatment of roasted rice with a protein content of 16.12%, fat content of 6.86%, water content of 68.83%, in terms of color and aroma, namely a good color and optimally evenly distributed and a distinctive aroma of bekasam and very sharp aroma. The quality value content of used toakang sepat fish has met the TKPI criteria and can be consumed.

Abstract

Process of science learning stresses on giving students direct experience to develop their competence. Therefore, teachers are required to be creative and innovative to improve students’ critical thinking. Accordingly, there is a need for a research on “The science learning based on guided inquiry integration with Numbered Heads Together (NHT) toward critical thinking skill”. This research aim to figure out of influence of the science learning based on guided inquiry integration with NHT. This research is a quasi-experimental study, with design "non-equivalent group control design". This research was conducted at September-December 2018 with samples of the experimental class (n = 40) and the control class (n = 40) at class VIII SMP N 21 Pekanbaru. The research instrument consisted of questions to test students' critical thinking skills. This shows the research instrument at a good and quality stage. The results of this study note that there are significant differences in the average value of the Post test students' critical thinking skills between the experimental class amounted to 75.00 with the control class 67.00 after the intervention (P <0.05). So that the use of Integration of guided inquiry with NHT in the learning process can improve students' critical thinking skills.

Abstract

The K13 Curriculum requires students thinking skills, especially in the regulation of cognition which consists of planning, information management strategies, monitoring, examination of actions, and evaluation. This study aims to look at the metacognitive abilities of class X students of SMAN 7 Pekanbaru on the concept of environmental pollution through mind mapping with problem based learning models. This type of research was a quasi experiment using two classes, one class as an experimental class and one class as a control class. The experimental class used mind mapping models of problem based learning and the control class used conventional learning. The research design used a pretest-posttest control group design. Data collection techniques used questionnaires metacognitive abilities and description test questions. The analysis technique used the Anova test analysis. The results of the pretest and posttest showed a significant increase in students metacognitive abilities through mind mapping with the problem based learning model of the concept of environmental pollution at SMAN 7 Pekanbaru with a significance value of 0,000. Sig. (0,000) < then H0 is rejected, so it can be concluded that the metacognitive abilities of students are increased through mind mapping with problem based learning models on the concept of environmental pollution.
