This research was conducted to: (1) improve the science domain based learning tool which is integrated with appropriate local wisdom for Science learning material "Object Change Around Us" for students grade VII of Junior High School, (2) know the effectiveness of science based learning tool which is integrated with developed local wisdom to improve science process skill and scientific attitude of students grade VII of Junior High School. This research was a research and development which adapt 4D Thiagarajan model which include four steps, they were: (1) define, (2) design, (3) develop, and (4) disseminate and Borg & Gall development model which was done into 7 steps, they were: (1) research and information collecting, (2) planning, (3) developing preliminarry form of product, (4) preliminary field testing, (5) main product revision, (6) main field testing, and (7) operational product revision. The research result showed that the science domain based learning tool which was integrated with developed local wisdom were: (1) appropriate to be used for science learning material "Object Change around us" for students grade VII of JHS, (2) effective to improve science process skill and scientific attitude of students grade VII of JHS.

One of the mangrove forests in Indramayu, West Java, Indonesia that plays an essential role in the environment and becomes a learning center, is the Karangsong mangrove forest. The study aimed to determine the feasibility and effectiveness of Enrichment E-Module of Mangrove Ecosystem (EMME) to improve students' self-regulated learning. This study was Research & Development with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). This study was conducted at a Senior High School in Sindang, Indramayu, Indonesia with ten (X) grade of science class. The samples were chosen using a purposive sampling technique, resulting in class X-7 chosen as a control group and class X-8 as an experimental group. The design of this study used a non-equivalent control group design. The average validation result by experts was that media expert of 87.75 (very feasible), material expert of   94.36 (very feasible), and biology teacher of 93.40 (very feasible). The results indicated that the enriched e-module of the mangrove ecosystem was feasible in enrichment learning. E-module did not significantly influence to improve students' self-regulated learning, as seen from the result of the Mann Whitney test (0.077). Improvement of students' self-regulated learning was low, as seen from the N-gain score of the control group (0.06) and the experimental group (0.20). These concluded that the e-module of the mangrove ecosystem could be used in the learning, and short time allocation causes the module not to influence self-regulated learning significantly. Several revisions are needed in order to make the e-module more effective in improving students' self-regulated learning.

This study aims to analyze the influence of science learning integrated with the local potential of wood carving and pottery to the critical thinking skill of class VIII SMP students. This research is a quasi-experimental research (quasi-experiment). The research design uses pretest-posttest control group design. The population in this study is the students of class VIII MTs Negeri Piyungan, while the sample is the students of class VIII A and VIII B MTs Negeri Piyungan. The technique of collecting data in this research is in the form of test. The data collection instrument is a critical thinking skill descriptive test. The data were analyzed using ANOVA test. The results of this study indicate that the learning of science integrated with the local potency of wood carving and pottery have an effect on critical thinking skill of class VIII SMP student. This effect is indicated by a significance of 0.008 (significance <0.05).

Penelitian ini bertujuan untuk mengetahui keefektifan dan kelayakan web-LKS IPA terintegrasi lingkungan lahan gambut. Penelitian ini merupakan penelitian pengembangan dengan model 4D (define, design, develop, dan disseminate) dan desain penelitian pretest posttest control group design. Penilaian kelayakan produk web-LKS IPA dilakukan oleh ahli materi, ahli media untuk kelayakan produk, guru IPA sebagai penilai kepraktisan dan respon siswa untuk mengetahui keterbacaan produk. Perolehan skor hasil penilaian kelayakan oleh ahli materi sebesar 53 (sangat baik) pada skor maksimal 56, oleh ahli media sebesar 38 (sangat baik) pada skor maksimal 40 dan penilaian kepraktisan oleh guru IPA dengan skor 53 (sangat baik) pada skor maksimal 56. Uji keterbacaan oleh siswa memperoleh persentase sebesar 95% dengan respon positif. Hasil skor gain ternormalisasi menunjukkan peningkatan dalam pembelajaran dengan perolehan skor rata-rata sebesar 0,51 pada kelas eksperimen dan tergolong pada kategori tinggi. Uji independent sample t test digunakan untuk mengetahui keefektifan dengan nilai signifikansi sebesar 0,000 (> 0.05). Hasil penelitian menunjukkan bahwa pembelajaran IPA dengan menggunakan web-LKS IPA terintegrasi lingkungan lahan gambut efektif meningkatkan literasi lingkungan siswa SMP Negeri 1 Pelaihari. Web-LKS natural science integrated local potential of peatlands to increase student environmental literacy  AbstractThis study aims to determine the effectiveness and feasibility of an integrated IPA LKS web environment. This research is a development research with a 4D model (define, design, develop, and disseminate) and a pretest posttest control group design. Assessment of the feasibility of science-based LKS web products is carried out by material experts, media experts for product feasibility, science teachers as assessors of practicality and student responses to know the readability of the product. The score obtained by the feasibility assessment by material experts was 53 (very good) at a maximum score of 56, by media experts at 38 (very good) at a maximum score of 40 and practicality assessment by science teachers with a score of 53 (very good) at a maximum score of 56. Readability test by students gets a percentage of 95% with a positive response. The normalized gain score results showed an increase in learning with the acquisition of an average score of 0.51 in the experimental class and belonging to the high category. The independent sample t test was used to determine effectiveness with a significance value of 0,000 (> 0.05). The results showed that science learning by using an integrated science-based LKS web environment effectively improved peatland environmental literacy of Pelaihari 1 Junior High School students.
