Abstract

AbstractTotal Productive Maintenance been implemented by PT. Hamatetsu Indonesia to boost manufacturing firms' overall effectiveness and efficiency. The objective of this research is to determine the value of the tools' effectiveness, identify its root cause, and offer suggestions for improvement. This study is a quantitative narrative based on Total Productive Maintenance (TPM) maintenance procedures designed to improve work area productivity by reducing waste and increasing reliability. In this study, interviews and direct observation were used to collect data. The obtained results indicate that the Part Piston Cup Forging production process is prone to five types of failure, namely: Reduced speed resulted in a total loss of time of 328.2, a defect in the process resulted in a total loss of time of 148.35, equipment failure resulted in a total loss of time of 11.34, setup and adjustment resulted in a total loss of time of 114.74, and idle and minor stops resulted in a total loss of time of 433.7. Additionally, there are two types of process failures identified by FMEA Processing's findings: defects that occur in the process as a result of failure effects, such as product defects that arise during the process, and defects that occur in the process as a result of failure effects, such as a decrease in machine speed. The tool on the machine, which is no longer suitable for use, and the machine's age both contributed to the process's failure.Keywords: PT.

Abstract

AbstractOne of the causes of river pollution is the presence of waste in water bodies which causes substantial water quality deterioration. The Ciliwung River is one of Indonesia's most polluted rivers with a very high level of pollution. This study aimed to estimate the amount of daily waste generation in water bodies and theircomposition characteristics. Waste samples were taken from segment 4 of Ciliwung River, namely Jalan Juanda Depok. The waste collection method uses a trawl boom and a trap net. The results showed that the average daily waste generation in the Ciliwung River is 323.87 kg/day (standard deviation of 366 kg/day), with the composition of waste dominated by organic waste as much as 68.63%, plastic waste 15.54%, textile waste 10.89%, and other waste 4, 54%. Fluctuating composition results may be caused by weather, sampling locations, and surrounding activities. The average waste generation in Ciliwung River in theliterature is 970 kg/day. The difference in estimates is because 33 illegal waste collection points along segments 5 and 6 of the Ciliwung River are suspected of leaking into the water body. The difference in estimates is also influenced by the percentage of unmanaged waste in DKI Jakarta which was about 0.9%.Keywords: waste generation, waste composition, trawl boom, Ciliwung, waste collection

Abstract

AbstractOne of the impacts of climate change is the degradation quality of natural habitats of flora and fauna in Indonesia, risking the loss of most of the existing biodiversity. Obi Island as a natural habitat for several endemic species cannot be avoided from the threat of climate change impacts. The existence of mining concessions also can have a direct impact on their habitat potential. The purpose of this study was to analyze the distribution pattern of endemic species under current climatic conditions, synthesize models of the impact of climate change and analyze mining concessions on the distribution of potential habitats of Carunculated Fruit-dove on Obi Island. The occurrence data of Carunculated Fruit-dove and 19 bioclimatic variables are used as input in the process of making a habitat model with MaxEnt. As a result, the habitat potential model of Carunculated Fruit-dove with AUC = 0.955 has a very suitable habitat potential with an area of 66.02 km2 or 2.68%. The climate change in 2041-2060 with 4 different climate scenarios has an impact on the Carunculated Fruit-dove habitat potential model. Mining Business Permit Areas on Obi Island that have been issued until March 2022 amount to 19 locations with a total area of 373.14 km2 which will have a direct or indirect impact on the potential habitat of Carunculated Fruit-dove on Obi Island. 14.17 km2 of 66.67 km2 of potential habitat that is very suitable for Carunculated Fruit-dove will be directly affected by the existence of these mining areas.Keywords: endemic species, mining business permit area, climate change, obi island, maximum entropy

Abstract

AbstractResidual chlorine levels in water need to be maintained in the distribution network to prevent the presence of pathogens in drinking water that can be consumed by humans. According to Minister of Health Regulation No. 736/Menkes/PER/VI/2010 concerning Procedures for Monitoring the Quality of Drinking Water is in the range of 0.2 – 1.0 mg/l. This simulation was carried out to analyze the presence of residual free chlorine in the PDAM Padang, North Region distribution network sourced from the IPA Palukahan using EPANET software. Analysis of chlorine decay to determine the coefficient of bulk reaction and wall reaction was carried out at the Palukahan Reservoir outlet pipe for 6 hours using the DPD method. The dose of adding chlorine to the reservoir is 2.20 mg/l. The residual chlorine simulation results obtained a Global Bulk Reaction value of -0.105 and a Global Wall Coefficient value between -0.1 to -0.5 ranging from 0.12 mg/l – 2.20 mg/l. Low residual chlorine i.e., 1 mg/L, is located at a distance of 10-12 km from the reservoir, while high residual chlorine value, namely 1 mg/L, is located at 1-5 km from the reservoir. The results of this simulation show that chlorine levels in some distribution pipeline networks did not meet the drinking water regulation. The simulation results show that the dose and pipe spacing affect the remaining chlorine received by the customer.Keywords: disinfectant, distribution network, Padang City Water Supply Corporation (PDAM), remaining chlor, EPANET simulation

Abstract

AbstractJusticia gendarussa Burm.f has been traditionally used as male contraceptionin in Indonesia. Gandarusa leaves contain gendarusin A which has potential as an antifertility agent. To prove that gandarusa leaves are safe to use as a male contraceptive, a subchronic toxicity test was carried out on this plant. Acute and subchronic oral toxicity studies of Justicia gendarussa Burm.f in rats were performed in the previous study in order to evaluate its safety. The aim of this study is to identify the metabolite profile of rat organ results of their subchronic toxicity test. Seven organs of rat such as kidney, hepar, testis, limph, instestine, lung, and heart were extracted using methanol and their profile metabolites were identified using UHPLC Vanquish Tandem Q Exactive Plus Orbitrap HRMS by positive and negatif mode. The results showed that all sampels contain 22 compounds from the positive ionization mode and 35 compounds from the negatif ionization mode. Compounds identified from the positive mode were dominated by amino acid groups, then compounds identified from the negatif mode were dominated by fatty acids and their derivatives. There were 35 metabolites that identified from the organ samples of the rat resulting subchronic toxicity test using the UHPLC Vanquish Tandem Q Exactive Plus Orbitrap HRMS method.Keywords: Justicia gendarussa Burm.f, rats, organ, metabolite profile
