Abstract

This study aims to analyze the Fresh Fruit Bunch Boiling Process at the Sterlizer Station in Palm Oil Processing at PT. Sumber Bumi Sawit Jadi Jaya. In writing this report, data collection is very important. The data collection methods used by the author are as follows: Documents or References Data collection through written and electronic documents from PT. Sumber Bumi Sawit Jadi Jaya. Field Observation. The method is carried out by direct observation in the company environment. Literature Review. In addition to field observations, data is also taken from several literatures related to this report. The location of the field work practice was held at PT Sumber Bumi Sawit Jadi Jaya which is located on Jalan Besar Mandoge-Kisaran. And the field work practice lasted for 1 month. Starting from September 1st – October 1st, 2023. The conclusions obtained from the results of the practical work are as follows: PT. Sumber Bumi Sawit Jadi Jaya is a factory that processes fresh oil palm fruit bunches into CPO and palm kernel. The processing capacity at PT. Sumber Bumi Sawit Jadi Jaya is 30 Tons of FFB / Hour The organizational structure at PT. Sumber Bumi Sawit Jadi Jaya is a functional organizational structure. The results of processing the percentage of cardiovascular load obtained that all boiler workers needed repairs, and the workload category of the four workers was influenced by age factors

Abstract

This study aims to Test Wastewater Quality Using the Mpn (Most Probable Number) Method to Detect Total COLIFORM Bacteria. This study uses laboratory analysis, which aims to provide an overview of the microbiological quality of wastewater based on the presence and number of Coliform bacteria. The working principle of the Most Probable Number (MPN) method in detecting total Coliform bacteria in wastewater is carried out semi-quantitatively by detecting microbial growth through lactose fermentation which produces gas or turbidity in selective liquid media. The implementation procedure includes a presumptive test stage using Lactose Broth (LB) media, a confirmatory test with Brilliant Green Lactose Bile Broth (BGLB) media, and determining the final value by matching the combination of positive tubes with the standard MPN table. From the results of laboratory testing on three domestic wastewater samples (1224 AL, 1225 AL, and 1226 AL), it was found that all samples showed negative results with a combination of 0-0-0 tubes in the presumptive test. This indicates that the tested sample does not contain Total Coliform bacteria or has a value of less than 1000 MPN/100 mL, so that its microbiological quality is declared very good and has met the quality standard threshold set by the government through the Minister of Environment Regulation No. 5 of 2014 and PP RI No. 22 of 2021

Abstract

This  research  aim  For  knowThe  Influence  of  the  Project  Based  Learning  Model  on  Learning Outcomes PPKN On Students of Class IV of UPTD SD Negeri 122350 Pematangsiantar.Research design implementedis  Pre-Experimental  Designs  method  is  appropriate  with  limitations  amount  samples  to  be researched.This research will was held at the UPTD of State Elementary School 122350 Pematangsiantar.The time study implemented in the even semester May of the Year Academic Year 2023/2024. Based on results  research  and  discussion  that  has  been  put  forward  can  taken  conclusion  that  from  pretest  results,obtained the average value is 46.35 which is classified as in category low.While average value of results Study posttest students, namely 85.52, which indicates that results after given treatment increase with such a  range  big.From  the  average  pretest  and  posttest  scores  there  are  difference  of  39.17  and  based  on hypothesis test results with level significant = 0.05 and ttable of 2.034, thitung of 14.737. With thus thitung> ttable 14.737> 2.034, then can concluded that there is the influence of the Project Based Learning Model on results learning PPKN for students  Class IV of UPTD SD Negeri 122350 Pematangsiantar.Maka based  on  Hypothesis  Test  Results   is  rejected  and accepted  which  indicates  that  existence  the influence of the Project Based Learning Model is significant to results learning PPKN for students  Class IV of UPTD SD Negeri 122350 Pematangsiantar.
