This study aims to determine the effect of the application of guided inquiry learning models with the practice of converting heat to electricity to improve critical thinking skills. The population of this research is all students of class XII Science of SMA Negeri 1 Way Jepara. The selection of research samples using purposive sampling techniques with a sample of class XII Science 5 totaling 33 students. The research design used was One Group Pretest-Posttest. Learning is done by conducting practicum activities using a set of guided inquiry-based heat energy conversion devices. The tool used in practicum activities is an advantage in this study because there has been no previous research that uses practicum learning methods with tools to convert heat energy to electricity. Practicum activities carried out on two learning topics or practicum twice. In practicum activities topic one is about the unit thermoelectric generator module specifications and in practicum activity topic two is regarding the thermoelectric generator circuit to turn on the LED lights. Data were tested by N-gain analysis, normality test, Paired Sample T-Test. Based on the results of the Paired Sample T-test, it can be seen that the significance value of 0.00 is less than 0.05, it can be concluded that there is an influence of students' critical thinking skills before and after using guided inquiry learning models with energy conversion practicum.
本研究的目的是确定指导性研究性学习模式的应用效果与实践的热量转换为电力，以提高批判性思维能力。本研究的人群为SMA Negeri 1 Way Jepara科学12班的所有学生。研究样本的选择采用有目的的抽样技术，以科学5 12班共33名学生为样本。采用一组前测后测的研究设计。学习是通过使用一套引导式探究式热能转换装置进行实习活动来完成的。在本研究中，实习活动中使用的工具是一个优势，因为之前没有研究使用实习学习方法与工具将热能转换为电能。针对两个学习课题进行实习活动或两次实习。在实习活动的主题一是关于单位热电发电机模块的规格，在实习活动的主题二是关于热电发电机电路打开LED灯。数据采用n增益分析、正态性检验、配对样本t检验。从配对样本t检验的结果可以看出，显著性值0.00小于0.05，可以得出使用能量转换实习的引导探究学习模式前后对学生批判性思维能力有影响的结论。

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.

Rainfall variability in Indonesia could be affected by global phenomenon like La Nina 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 Nina of 2010 affected the amounts of rainfall that is greater than its average in Jembrana Regency Bali. La Nina of 2010 affected the amounts of rainfall that is greater than La Nina period of the previous years.
