This study aims  to determine the validity of the development of website-based science learning media on invertebrate animal material for grade 7 in Junior High School, and to determine student responses to the development of website-based science learning media on invertebrate animal material. This research was a type of R&D (Research and Development) research which refers to the ADDIE (Analysis, Design, Development, Implementation and Evaluation) development research model of Robert Maribe Branch. The data collection instruments in this study were validation questionnaires and student response questionnaires. Validation was carried out by material experts, media experts, and science teachers. The development trial to determine student responses to the developed product was carried out in two stages, namely a small-scale trial consisting of 6 students and a large-scale trial consisting of 32 students. Based on the results of validation from experts on website-based science learning media, it showed that the assessment of material experts was 96.16%, media expert assessments was 89.12% and assessments from science teachers was 89.83% . In this case, the average percentage of the expert's assessment was 91.70%, which means it was included in the "Very Valid" category and tested on students, and Small-scale trials obtained an average percentage of 94.28%. Then continued large-scale trials and obtained an average percentage of 92.00%. which means “Very Interesting”.

Research and development of sigil-based teaching materials based on facts in yhe field, namely students rarely read textbooks in printed form because the display is less attractive, additive and addictive substances have not been delivered as a whole so thaht astudents miss lessons and lack insight. When in class students tend not to play attention because the learning used by teachers is often convensional and rarely uses media. Teaching materials are needed by students in learning activities that can be used anytime and anywhere so that learning activities can be efficient. The purpose of the study was to describe the results of validation and student responses to sigil-based teaching materials for junior high schools. This type of research is the research and development of R&D (Research and development). The development model in this study uses a model developed by Thiagarajan 4-D. The product that has been developed is then validated by 2 (two) lecturers from the Faculty of Tarbiyah and teacher Training consisting of material experts and media experts as well as one science teacher of SMP Plus Darus Shlolah as user expert. After being validated, the product is then field tested to determine student responses. The results of the materials expert assessment are 98.75%, 91.42% media expert and 92.30% user expert, all three have a high percentage so that the developed digital teaching material has the criteria of “very valid”. The small-scale trial results showed a percentage of 78.4% so they included the criteria of “interesting”. Large-scale trial results the percentage of results is 83.3% so it includes the criteria of “very interesting”.

The survey results on teachers and students in six regencies/cities in Lampung Province showed that in science learning, teachers have not optimized the argumentative skills of students. Thus, this study aimed to develop and validate science worksheets oriented to the argumentative skills of students. This study used a 4D-study design with Argument-Driven Inquiry (ADI) learning model. A small-scale trial was conducted on 20 IX-graders at SMP 9 Krui Pesisir Barat. The large-scale trial was conducted on 50 IX-graders at SMP 9 Krui Pesisir Barat by purposive sampling with one experimental class and one control class. The control class used a worksheet from a particular publisher, and the experimental class used the developed worksheet. Based on the results, the ADI model worksheet can be declared valid in terms of content, construction, and language with an average of 92.3% with very high criteria. The practicality of the ADI worksheet model can be seen from the implementation of learning, student responses, and teacher responses had an average of 89.24% with very high criteria. The effectiveness of the ADI model worksheet can be seen from the ability to work on argumentation skills test questions, showing that the control class N-gain was 0.27 with low criteria and the experimental class was 0.57 with medium criteria. The effect size (SE) of 0.64 showed that the developed science worksheet was effective in developing argumentative skills of students with medium criteria

IPA Integrated is a place for students to study themselves and the surrounding environment applied in daily life. Integrated IPA Learning provides a direct experience to students through the use and development of scientific skills and attitudes. The importance of integrated IPA requires to pack learning well, integrated IPA integration with the preparation of modules combined with learning strategy can maximize the learning process in school. In SMP 209 Jakarta, the value of the integrated IPA is obtained from 34 students there are 10 students completed and 24 students are not complete because they get the value below the KKM of 68. This research is a development study with the development model of ADDIE (Analysis, Design, Development, Implementation, and Evaluation). The use of KPS-based integrated IPA modules (Science Process sSkills) on the theme of rainbow phenomenon obtained by media expert validation results with an average score of 84.38%, average material expert 82.18%, average linguist 75.37%. So the average of all aspects obtained by 80.55% is worth using and tested to students. The results of the teacher response obtained 88.69% value with excellent criteria. Student responses on a small scale acquired an average score of 85.19% with highly agreed criteria and on the large-scale student response gained a yield of 86.44% with very agreed criteria.

Scheduling track lines at a marshalling station where the objective is to determine the maximal weighted number of trains on the track lines can be modeled as an interval scheduling problem: each job has a fixed starting and finishing time and can only be carried out by an arbitrarily given subset of machines. This scheduling problem is formulated as an integer program, which is NP-Complete when the number of machines and jobs are unfixed and the computational effort to solve large scale test problems is prohibitively large. Heuristic algorithms (HAs) based on the decomposition of original problem have been developed and the benefits lie in both conceptual simplicity and computational efficiency. Genetic algorithm (GA) to address the scheduling problem is also proposed. Computational experiments on low and high utilization rates of machines are carried out to compare the performance of the proposed algorithms with Cplex. Computational results show that the HAs and GA perform well in most condition, especially HA2 with the maximum of average percentage deviation on average 3.5% less than the optimal solutions found by Cplex in small-scale problem. Our methodologies are capable of producing improved solutions to large-scale problems with reasonable computing resources, too.

This development research is motivated by the low learning outcomes of students and the lack of motivation students in learning chemistry, especially on solubility and solubility result at SMAN 1 Mandor. This study aims to produce worksheets based on chemo-edutainment student on solubility and solubility result. This type of research is the development of the ADDIE Research and Development (R&D) model. The instruments used were validation sheets, questionnaire sheet for teacher and student responses and test sheets for pretest and posttest questions. The analysis shows the validity criteria obtaine by the validator 1.0 value with a very valid category. The results of the questionaire respons of primary field trial students obtained an average percentage value of 88.57 %. The efective criteria for chemo-edutainment based worksheets were seen from the pretest and posttest results of students calculated using N-gain formula, the value obtained in the main field trial is 0.85 (very high). Based on these results, it can be conculuded that the development of chemo-edutainment based student worksheets is feasible to be used as teaching material on solubility material and solubility results in class XI IPA in SMAN 1 Mandor.
