Abstract

The competence of science teachers in Padang City Junior High Schools in developing learning tools is still low, as revealed by the teacher's pre-test abilities before the workshop is held. Pre-test includes gathering information about learning resources, learning media, models / methods / approaches, and assessment instruments used by teachers not yet utilizing the environment. Referring to the problems of teachers, problem-based workshop activities are designed in an effort to improve teacher competencies in designing learning tools based on environmental potential. Problem-based workshops have stages: (1) problem identification, (2) Focusing on problems, (3) Finding alternative solutions, (4) Presentation of solutions; (5) Implementation and (6) Reflection & follow-up. The workshop was attended by 20 junior high school science teachers in Padang city. The workshop activities consisted of 2 parts, namely the workshop activities at FMIPA UNP and the Implementation activities at SMP 25 Padang. Problem-based workshops succeeded in increasing teacher competence in designing IPA-based environmental learning tools. The results of the implementation of the workshop products by the teacher showed a positive influence on student involvement and activity in learning

Abstract

Classroom Action Research (CAR) is one of the activities which teachers must carry out to improve and develop their professionalism. This community service activity aimed at train and improve the professionalism of chemistry teachers through CAR activities. The method was conducted with lectures, discussions, questions and answers, and workshops on proposal preparation, literature searching, CAR implementation, report, and CAR research articles preparation. The number of participants is 34 who are the members of MGMP Kimia Kabupaten Tanah Datar. There were six meetings with the total time was 36 hours in July-December 2019. The instrument used was a questionnaire. The data obtained were analyzed using the percentage and equation techniques of Kappa Cohen's. Based on the results, of the 34 participants, 15 CAR titles were obtained, 11 CAR titles were carried out, 8 CAR reports were produced, and 4 CAR articles were drafted. Based on the teacher's questionnaire responses, the kappa moment average value was 0.86 which categorized as very high. This data showed that the classroom action training activities provided can improve the professionalism of chemistry teachers in preparing proposals, implementing, drafting reports and articles. This training activity still needs to be continued to obtain CAR articles that have been published in several national /international journals or proceedings.

Abstract

Writing students worksheet is a routine task for each teacher. In this workshop, teachers design the worksheet using lesson study approach. Before design the learning material which is lesson plan and student’s worksheet, the teacher remind the basic concept of probability theory and its related topic. Related topics discuss are probability function, special distribution function, they are binomial and normal distribution. As assessment to the teacher, the devotee gave pretest in the first meeting and post test at the end of workshop. It item consist of lesson study concept, probability function, binomial and normal distribution. Depend on it, we see the increment of teacher’s competency.

Abstract

Control of plant diseases is usually carried out by the community using chemical pesticides. These chemical pesticides can damage the environment and human health. As an alternative, a technique for using fluorescent pseudomonad biological agents has been developed as an antagonistic, environmentally friendly microorganism to reduce the negative impact of using chemical pesticides. Community service has been carried out in Korong Kampung Guci Nagari Lubuk Pandan, Padang Pariaman regarding the application of compatible fluorescent pseudomonad biological agents. After the material was presented to the participants, it was continued with the application of compatible fluorescent pseudomonads to the tissue cultured rhizosphere of banana plants. All participants enthusiastically applied compatible fluorescent pseudomonads in the field.
