Abstract

Water treatment plants (WTPs) are critical to providing clean, safe and compliant drinking water. However, the use of chemicals and electrical energy in the process can have a negative impact on the environment.This study examines the environmental impact of WTPs using Life Cycle Assessment (LCA) methodology and SimaPro software. The study aims to investigate how the process of treating clean water affects the environment and to provide a more environmentally friendly replacement for WTP. SimaPro 9.0 is used in the LCA technique of environmental impact assessment. This includes defining the objectives and parameters of the study, collecting data (Life Cycle Inventory), analysing the results (Life Cycle Impact Assessment) and interpreting the data. According to the results of the analysis, the reservoir and lamella units are the main sources of impacts in the Endpoint Impact category. The impacts produced by the Impact 2002+ and ReCiPe 2016 approaches differed, with ReCiPe 2016 showing stronger impacts in certain categories. This study sheds light on how the WTP's clean water treatment process impacts the environment. Reducing the use of chemicals, increasing energy efficiency and implementing environmentally friendly technologies are some suggestions for improvement.

Abstract

The drying process in this study was carried out using a tray dryer at a drying air temperature of 60oC and a relative humidity of 17.8% by varying the flow rate, namely 1.6, 2.4 and 3.2 m/s. An analysis of the decrease in water content and drying rate constant was carried out to determine the effect of variations in flow rate on these two parameters based on experimental data and corroborated by correlation analysis and statistical significance. Variations in the flow rate of the drying air have an impact on reducing the water content of the butterfly pea flower by 57-60%, where based on the significance test, the results show that the relationship between the two variables is not statistically significant. In addition to the reduction in water content, the drying rate constant was also investigated in this study, where the largest drying rate constant was 0.0154 kgH2O/m2.minute when a drying air flow rate of 3.2 m/s was used.

Abstract

Hydropower with a cascade scheme utilises the energy potential of water in a sustainable manner. The Brantas River area is used to generate 4 (four) hydropower plants (HEPP) that are arranged in series from upstream to downstream, namely Sengguruh HEPP, Sutami HEPP, Wlingi HEPP and Lodoyo HEPP. From December 2022 to November 2023, the four hydropower plants can produce 888,629,472 kWh of electricity. However, there is still potential for electricity generation that can be optimised from the unused water potential (spillwaywater) of 553.61 million m3. The optimisation management system provides a solution for utilising water energy sources by formulating a mathematical model using Solver in the Microsoft Excel application to plan the water level of the Sutami reservoir, hydropower load settings and peak/off-peak times at each hydropower plant. By implementing an optimisation, electrical energy production has the potential to reach 951,796,287 kWh or an increase of 7.11% in the period December 2022 to November 2023 by minimising the occurrence of spillway water by up to 92.40% or 551.61 million m3. As a result, the cascade efficiency of the hydropower plants of the Brantas River cascade was increased by 2.87% or 0.003 kWh/m3.

Abstract

This company is an industry that operates in the field of printing boxes made of paper such as duplex, ivory, art paper, mirror coated, HVS and the like. This company uses a make-to-order system or what is known as a production strategy where the company makes products based on customer orders. The production process of this company starts from printing, finishing, laminating, gluing, packing and sorting. The problem in this company is in the gluing section, especially when the packing is done manually and in a bent position, which can cause fatigue if done for a long period of time and can lead to certain muscle disorders or musculoskeletal disorders (MSDs). Therefore, the researcher proposes to design a tool that can support the production of gluing, especially the packaging part, by designing a carton sealing tool so that the packaging process can be speeded up and the level of fatigue caused by an uncomfortable working position can be reduced. This research uses data collection methods by means of interviews and observations of workers' complaints of discomfort, so that the results are complaints of fatigue, namely in the shoulders, back and waist. Based on the results of these observations, it is necessary to design tools to make them more comfortable and increase production output.

Abstract

Electricity problems encountered on a daily basis cannot be separated from the problem of high electricity prices and electricity shortages that still exist in several areas of Indonesia. This paper will analyse the renewable energy potential of Tello Island and the feasibility study of building a power plant, as well as the carbon offset that can be reduced by switching from fossil energy to renewable energy. The use of solar panels as a hybridisation of a diesel power plant will reduce the use of fossil fuels. Based on the economic analysis of the PLTS on Tello Island, it can be concluded that the initial investment cost for the design of the PLTS system on Tello Island was IDR 2,467,599,996. With an NPV of IDR 416,062,532 (>0), a B-CR of 1.17 (>1), a PBP of 1.45 (< investment period), which is 1 year and 5 months, and an IRR of 26%, it shows that the investment in solar power plants to be designed in the Tello Island building is feasible. Based on the automatic screening carried out on amdal.net, the electricity generated in one area only requires effort documents Environmental Management and Environmental Monitoring Effort (UKL & UPL), do not require AMDAL because the solar power plants built include low voltage. If it is assumed that the diesel power plants on Tello Island consume 60% of the electricity, the CO2 eq produced is reduced to 600 CO2 eq for the production of 750 kWh.

Abstract

The distribution process is, of course, closely related to transport, as transport acts as a means of movement or delivery from the warehouse to the destination. PT Pupuk Indonesia is the largest fertiliser producer in Asia and is the official fertiliser producer. PT Pupuk Sriwidjaja (Pusri) Palembang is part or group of PT Pupuk Indonesia. PT Pupuk Sriwidjaja (Pusri) carries out deliveries by land and sea transport. PT Pupuk Sriwidjaja (Pusri) only uses trucks as land transport equipment to distribute fertiliser, so this research will focus on truck transport. The purpose of this research is to identify the strategies used by companies to prevent product damage during the transfer process from warehouse to land transport. The research method used is a qualitative method with a descriptive approach and the research design is a case study of the handover process. The outcome of this research is to find out the problems during the handover process, namely loss of fertilizer, shrinkage of fertilizer, damage to fertilizer bags such as bag leaks and deformed bags due to dirt. Also find out what strategies the company has in place to prevent product damage.
