<![CDATA[Method has been carried out. Research is done on mild steel zincalume type with immersion treatment (NaCl 3.5%) for 10 days, and 30 days and without immersion. Mild steel is laser irradiated (Nd-YAG 1064 nm, 7 ns) with energy of 120 mJ, and the data is taken with an accumulation of 3, delay time of 0.5 µs. Elements identification is done by taking data from up to 75 μm from the surface. The results of the analysis with LIBS showed immersion for 10 days, the corrosion rate and hardness of mild steel increased with 30 days immersion. The increase in the corrosion rate of mild steel is indicated by decreasing the value of dissolved oxygen intensity, the electrochemical reaction is fast. The decrease in the corrosion rate is indicated by the increase in the intensity value of Zn and Al elements associated with the formation of a passive film on the metal surface as a protective layer to protect further corrosion attacks.DOI : 10.29408/kpj.v5i1.3446]]>

<![CDATA[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. 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.]]>

<![CDATA[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.]]>
