Abstract:This research aims to develop and determine the quality of physics learning modules based on contextual on the material of rigid dynamics of rotation and equilibrium for class XI students. The research method used is the Research and Development (R & D) method which includes; analysis of potential and problems, data collection, product design, design validation, design revisions, product trials, product revisions, and usage tests. The data in this research were analyzed qualitatively deskriptive. The subject of this research included three lecturers and two physics teachers as experts, as well as students of class XI IPA MA NW Kotaraja. The research instrument used was the validation sheet and student response sheet. Design validation resulted in a score of 3.29, a product trial yielded a score of 3.17, and a trial of use resulted in a score of 3.23.

Abstract:This study aims to determine the effect of demonstration methods using virtual and real laboratories on science process skills of class VIII students of SMPN 2 Sikur 2018/2019 academic year. This type of research is experimental research, with post test only control group design. The population in this study were all eighth grade students who numbered 4 classes. The sample was determined by cluster sampling technique, and class VIII-B was obtained as the experimental class and VIII-D as the control class. The data collection technique used is the test technique. Test techniques are used to measure students' science process skills in science subjects. The prerequisite test used is the data normality test using Kolmogorov smirnov and the homogeneity test using Leaven Test with a significance of 5% in SPSS Version 20. While to test the hypothesis in the study using the Independent T-Test Sample Test on SPSS Version 20.

Abstract:This research aims at; (1) describe the characteristics of the Physics module in material with ESQ for grade X SMA / MA. (2) get Physics module with ESQ for grade X SMA / MA who are eligible based on criteria. The method of this research using R & D with the reference of model 4-D (four D model) proposed by Thiagarajan, Semmel (1974). Model 4-D consists of definition, design, development and dissemination. The module is arranged with a load of emotional spiritual quotient (ESQ) which consists of developing knowledge, students can find a solution to their problems, provide a productive learning environment, creating a learning climate of physical and social for students, and engage students optimally in learning good emotional and spiritual. In addition, the module is also equipped with guided-inquiry stage as pillars in the module because it is a part of scientific approach that needs to be developed in 2013 curriculum. The module is assessed based on the feasibility of materials, media, and languages, as well as trials (limited and extensive) to students, and the deployment phase in MGMP. Data collection of the research used questionnaires and guidelines of analysis interview, validation sheet, questionnaire responses, the character values questionnaire, observation of character value, and disseminate questionnaire. The results of the study as follows: (1) physics module which contains six components of esq were well presented, expressed or implied, with guided-inquiry basis in it. (2) modules which are categorized as an adequateone with the calculation results (matter experts, media specialists, linguists, teachers, peers) that shows the average score of 86.0> cut-off 84.3. And supported by the positive response from students and disseminate results conducted on the MGMP forum categorizing as a good module. (3) the use of the module can empower the character value and knowledge of the student because > 75% can reach more than minimum score (KKM).

Abstract:Research has been done to identify radioactive elements and determine Work Level Month (WLM) values on workers in the sized room of 2m x 2m using gypsum material. Identification of radioactive elements in gipsum samples using Laser Induced Breakdown Spectroscopy (LIBS) methods and measurement of radiation dose in gypsum walls using surveymeter methods. Identification of radioactive elements to the LIBS method showed an element of Th, U, K were detected. The accumulated dose of radiation detected in the room using gypsum walls is (1,6993±0,0169) μSv and the accumulated dose of radiation detected in the room without gypsum walls is (0,5657±0,0292) μSv. WLM values from the room use a gypsum walls if workers work for 1 years is 0,9924 WLM, then it is still considered safe because it is still below the RR values that has been determined that is equal to 50 WLM.

Abstract:Rainfall variability in Indonesia could be affected by global phenomenon like La Niña by looking at the intensity value of Southern Oscillation Index (SOI) and anomaly value of SPL. The amount of these effect varies from one place to another. Jembrana Regency is one of the Regency of Bali Province. Jembrana Regency is located at 8°09'30" - 8°28'02" SL and 114°25'53" - 114°56'38" EL. The west and south border of Jembrana Regency are the sea which are Bali Strait and Indian Ocean, whereas the its east and north border are Buleleng Regency and Tabanan Regency. Rainfall pattern of Jembrana Regency has a peak of the rainy season between December – February and a valley of the dry season between June – August. From monthly rainfall data taken from the rain post of Poh Santen, Rambutsiwi, Palasari and Negara, descriptive statistical method was used to calculate the average monthly rainfall during the period of 30 years during period of 1981-2010. La Niña of 2010 affected the amounts of rainfall that is greater than its average in Jembrana Regency Bali. La Niña of 2010 affected the amounts of rainfall that is greater than La Niña period of the previous years.

Abstract:Belimbing wuluh merupakan tumbuhan yang masih kurang pemanfaatannya terutama pada buah belimbing wuluh. Dilihat dari kandungannya, belimbing wuluh mengandung asam format sehingga berpotensi untuk menghasilkan tegangan listrik sebagai sumber energi alternatif. Elektroda merupakan konduktor yang digunakan untuk bersentuhan dengan bagian atau media non-logam dai sebuah sirkuit. Tujuan penelitian ini adalah untuk mengetahui pengaruh luas penampang elektroda yang digunakan terhadap tegangan listrik yang dihasilkan dan menyusun sumber belajar dari hasil penelitian. Penelitian ini dilaksanakan di Laboratorium Pendidikan Fisika pada tanggal 3 april 2018. Metode pengambilan data menggunakan metode eksperimen dan metode pengolahan data menggunakan anava. Rancangan penelitian yang dilakukan adalah dengan membedakan luas penampang elektroda yang digunakan dengan masing-masing luasnya yaitu 4 cm², 10 cm², dan 16 cm². Menggunakan 900 ml bubur belimbing wuluh dengan melakukan 10 kali pengulangan pengambilan data. Berdasarkan hasil penelitian yang telah dilakukan didapatkan hasil tegangan listrik masing-masing luas penampang sebesar 1.385 volt, 1.75 volt, dan 1.945 volt.
