This research examines the physical and chemical properties of the potential contamination of condenser cooling water (heat water) at the 2x7 MW West Sumbawa Steam Power Plant. Method’s this research is direct observation in the field. The determination of the sample point was done by purposive sampling. The results showed that the hot water had met the predetermined quality standards, namely a pH of 8.21, a temperature of 38.50C and a content of free chlorine (Cl2) of 0.03 mg / L. There was an increase in sea water temperature in a radius of 17 meters east and west by 80C from 280C to 360C. Direct discharge of hot water has the potential to pollute the marine prawn environment around the 2x7 MW West Sumbawa PLTU. From the results of the study, it was found that the temperature of the hot water had met the specified quality standard, which was 40oC, but direct disposal caused the sea water temperature to rise, exceeding the set sea water temperature quality standard of 320C and the temperature increase should not be more than 20C from the temperature. at first. The status of sea water quality due to the entry of hot water is determined using a pollution index. From the calculation results obtained PIj of 1.125 at the sample point Outfall 2, meaning that the sea water conditions at a radius of 17 meters are lightly polluted. As a form of control and prevention of pollution due to the entry of high temperature hot water, continuous monitoring is necessary and it is necessary to create a mixing pool between sea water and hot water before the heat is discharged into the sea.
本研究考察了2x7 MW西松巴哇蒸汽发电厂冷凝器冷却水(热水)潜在污染的物理和化学性质。本研究方法为实地直接观察。采样点的确定采用目的采样法。结果表明，热水水质达到了预定的水质标准，即pH值为8.21，温度为38.50℃，游离氯(Cl2)含量为0.03 mg / l，东西17米半径范围内的海水温度从280℃上升到360℃，上升了80℃。直接排放热水有可能污染2x7 MW West Sumbawa PLTU周围的海洋对虾环境。从研究结果来看，热水的温度达到了规定的质量标准，即40℃，但直接处理导致海水温度上升，超过了设定的海水温度质量标准320℃，温度的上升幅度不应超过20℃。在第一位。利用污染指数确定热水进入后的海水水质状况。由计算结果可知，样本点Outfall 2处的PIj值为1.125，表示半径17米范围内的海水状况为轻度污染。作为控制和预防高温热水进入污染的一种形式，必须进行连续监测，并在热量排入海洋之前在海水和热水之间建立一个混合池。

The purpose of this study was to describe the application of the think-pair-share method with article analysis to improve students' higher order thinking skills. This type of research is pre-experimental with research subjects, namely students who take the Physics Learning Strategy course, academic year 2020/2021, at one of the universities in Mataram, totaling 27 people. The research design used was One Group Pre-test and Post-test Design. The instrument used in this study was a test of higher order thinking skills. The level of higher order thinking skills of students is calculated as a percentage, with 5 categories. The increase in score is calculated using N-gain, with 3 criteria. The results showed that the level of high-order thinking skills of students at the pre-test was 49 with a very low category, while at the time of the post-test it was 83 in the good category. The N-gain score is 68 with moderate criteria. Thus, the application of the think-pair-share method with article analysis can improve students' higher-order thinking skills in the Physics Learning Strategy course.

Student worksheets (LKPD) is the most significant aspect on the learning activities because it consists of the student’s learning process of gaining knowledge, primarily growing the critical thinking ability. The aim of the study is giving information about the development of critical thinking with LKPD process in physics subject. The method is Research and Development (RnD)-ADDIE which is limited on the development stage. Based on the evaluation result through validity which involve expert validity from the lecturer and the teacher, Content Validity Index (CVI) is 0,95 that means very suitable. The CVI result indicates that the LKPD process could be used to grow the physics critical thinking. The LKPD process has not arrived at implementation yet, hopefully the reseacher on the same field could apply till the implementation stage so that we could say LKPD process could grow the physics critical thinking.

The Delta Wing aeromodeling aircraft uses a symmetrical airfoil where the top of the wing is the same as the bottom. The main aspects in the design of the Delta Wing aircraft are center of gravity, the engine thrust, the air resistance, the lift and the weight. Delta Wing aircraft are dominated by jet-engined aircraft with the advantages of high speed and small air resistance. From the design and field trials, it was concluded that the minimum thrust of the Delta Win aircraft must be equal to 2 times the total weight of the aircraft so that the aircraft is able to maneuver vertically, perform looping maneuvers, roll maneuvers and hovering.

Based on data analysis results The conclusion that there is a significant difference between the results of learning before and after with a significance value of 0.000 < 0.05 and there is a significant relationship between student activity with the results of student physics learning after applied model based learning numbered heads together with significance value 0.028 < 0.05.
