Abstract

Penelitian ini merupakan penelitian pengembangan. Tujuan penelitian ini untuk menghasilkan modul kimia materi sistem koloid berbasis Problem Based Learning yang valid dan praktis. Model pengembangan yang digunakan adalah model ADDIE (Analysis, Design, Development, Implementation, Evaluation) dan dievaluasi dengan metode evaluasi formatif Tessmer. Tahapan evaluasi formatif Tessmer dalam penelitian ini meliputi self evaluation, expert review, one- to-one dan small group. Analisis data uji kevalidan dan praktisan menggunakan uji validitas aiken. Uji validasi pada tahap expert review menghasilkan rata-rata nilai koefisien Aiken sebesar 0,86  dengan  katagori  tinggi (sangat valid). Rata-rata nilai koefisien Aiken uji praktisan pada tahap one-to-one sebesar 0,89 dengan kategori tinggi (sangat praktis) dan small group memperoleh nilai 0,77 dengan kategori tinggi (sangat praktis). Hasil penelitian menunjukkan bahwa modul kimia materi sistem koloid berbasis problem based learning tergolong valid, praktis.

Abstract

Chemical bonding was one of the subjects considered difficult by students, because it had submicroscopic concept that learns about the formation of bonds an element that was quite difficult for students to understand. The development of teaching material in the form of teaching materials was seen as a solution to this problem. This study aimed to develop chemical bondinginquiry modelsteaching materials with conflict cognitive strategies towards critical thinking skills. This studywas development research with ADDIE (Analysis, Design, Development, Implementation, and Evaluation)model design. The development results were validated by three expert validators, one practitioner validator and ten IKIP Mataram students as students' limited test validators. Quantitative data from the results of feasibility validation and the results of the assessment of student attitudes toward critical thinking skills were analyzed by percentage formula and the results of effectiveness test data were calculated by N-gain. Qualitative data in the form of responses and suggestions for improvement from the validator was used as a consideration to make revisions to the instructional materials developed. In general, the validator's assessment of the results of the development obtained an average percentage of 83.80%, 85.71%, 88% and 85.71%. While the results of the analysis of effectiveness using the N-gain test obtained an average score of 0.6 with the medium category and analysis. This showed that the teaching materials developed were very feasible to proceed to a broader and more effective stage to foster critical thinking skills.

Abstract

Acid-base material is one subject that is considered difficult by students. In addition, students are less able to associate material with a problem or phenomenon in everyday life. The development of a teaching material in the form of modules can be seen as a solution to this problem. This study aims to develop a prototype in the form of developing contextual-based chemical modules to build students' conceptual understanding of acid-base material. This research is a development research with ADDIE model design (Analysis, Design, Development, Implementation, and Evaluation). The results of the development were validated by two expert validators, one practitioner validator and ten MA Al-Mansyurati NW Aik Bukak students as students' limited test validators. Quantitative data from the results of feasibility validation were analyzed by percentage formula. Qualitative data in the form of responses and suggestions for improvement from the validator are used as considerations to make revisions to the modules developed. In general, the validator's assessment of the results of the development obtained an average percentage of material expert validators 88.8%, product design expert validators 95%, practitioner validators 92%, and limited trials of students 85.28%. This shows that the developed module is very feasible to proceed to the effectiveness test phase. Thus it can be concluded that the contextually based modules are declared to be feasible with very good quality.

Abstract

One of the chemistry conceptsthat was considered difficult by students was acid-base concept. Acid-base conceptwas closely related to everyday life and includes three representations of chemical levels, namely: macroscopic level, microscopic level and symbolic level, so students experience difficulty in learning it. The development of a teaching material in the form of LKS was seen as a solution to this problem. This study aimed to develop teaching materials in the form of POE LKS oriented to green chemistry to foster students' scientific attitudes towards acid-base concepts. This studywas development research with ADDIE (Analysis, Design, Development, Implementation, and Evaluation)model design. Quantitative data from the results of feasibility validation and the results of assessment of scientific attitudes of students were analyzed by percentage formula and the results of student responses were calculated using N-gain. Qualitative data in the form of responses and suggestions for improvement from the validator. The validator's assessment of the results of the development obtained an average percentage of 83.2%, 84%, 81.6%, and 78.93%. While the responses of students were analyzed using the N-gain test obtained an average score of 0.4 with a moderate category and students' scientific attitude data obtained an average score of 61% with moderate qualifications. This showed that the LKS developed was very feasible to proceed to a broader stage and effectively improve students' scientific attitudes.

Abstract

Buffer solution is a material that requires a fairly high analysis withan understanding of concepts that must be understood by studentsand requires practice in everyday life. Learning will be moremeaningful and provide a deep understanding to the learner if thelearning is adapted to the characteristics of the subject matter. Oneeffective solution is to apply the learning model POE (Predict-Observe-Explain) oriented Chemoentrepreneurship. The aim of thisresearch was to evaluatethe influence of learning model POE(Predict-Observe-Explain) oriented Chemoentrepreneurship tounderstanding the concept and. This research was conducted inMAN 2 Praya, the population in this research was student of MIAclass XI, sample was taken by using saturated sampling technique.The design of this research is prettes-posttest control group design.The instruments used to measure conceptual understanding weremeasured using objective tests. Hypothesis testing was performed byusing One-Way ANOVA test with SPSS 15.0 for windows. Based onthe results of the study can be concluded that: Application oflearning model of POE (Predict-Observe-Explain) orientedChemoentrepreneurship influence to understanding student concept.This is evidenced by the sig value. of 0.00 < 0.05.

Abstract

In the processing of rice into the rice used is rice that has been whased away, while the rice water thrown away because it was considered important that the rice water that is not used will be waste, it is necessary alternative in their utilization. The alternative is to make a food product by a fermentation process using bacteria Acetobacterxylinum called nata de leri. It is caused rice water contain nutrients such as carbohydrates, protein, and vitamin B1 or thiamine. This study aimed to compare the volume and optimum mass of nutrients at chemical characteristicts of nata de leri generated. This type of research was Pre-Experimental by varying nutrient source used was suger as a carbon source and tofu waste water as a source of nitrogen. In this research, was adding four variations of nutrient source that has been 100:25 (g/mL), 125:50 (g/mL), 150:75 (g/mL), 175:100 (g/mL). Furthermore, the analisisproksimat include moisture content, ash content, fat content, protein content, and carbohydrate content. Best treatment combination was obtained on the addition of nutrient source 125:50 (g/mL) which generate 78,7217% moisture content, ash content of 1,0707%, fat content of 0,5636%, protein content of 0,4776% and the carbohydrate content 19,1893%.
