Abstract

Malang City has an increasing population every year, causing the amount of waste generated by residents and public facilities to increase. The waste is transported to the Supit Urang final waste processing site (TPA) located in Sukun District, Malang City. Currently, processing is still using the controlled landfill method so that a large area is needed for the landfill process. TPA waste generation data collection by load count analysis method. Analysis of environmental aspects was carried out using the Life Cycle Assessment method, the input and output processes used SimaPro v.9.0.0.47 software. In the analysis of technical aspects and environmental analysis, a projection of waste generation to the Supit Urang TPA is required, namely 189,989 tons / year in 2030. From the results of the analysis of technical aspects, it is concluded that the thermal treatment of mixed waste incineration is the best because it only requires a small amount of land, namely 1,385m2. , using 1 reactor and 14 workers. For the type of waste composition that produces the smallest emissions is the type of organic waste biowaste. The results of the environmental impact analysis of biowaste organic waste gasification processing are Global Warming 4,51E8 kg CO2 eq, Ozone layer depletion 1,74E3 CFC-11 eq, Photochemical oxidation 1,11E5 C2H4 eq, Acidification 2,21E6 kg SO2 eq, Eutrophication 3, 03E6 PO4 eq

Abstract

Livestock manure which is produced every day can be a problem for the environment if not handled properly. Vegetable waste is generally only allowed to accumulate in the market and immediately disposed of in a landfill without further processing, it can pollute the environment and disturb the aesthetics of the environment. Utilization of organic waste as raw material for renewable energy can be a solution. This study aims to determine the C/N ratio, methane gas production and flames produced from biogas production, as well as knowing the ratio of the ratio of substrate composition and the optimum time to produce the best biogas. This study combined Vegetable Waste (VW) and Cow Manure (CM) with ratio of 90:10, 70:30, 50:50, 30:70, 10:90. Variation of fermentation time was carried out for 5 days, 10 days, 15 days, 20 days and 25 days using a 19 liter volume reactor. The results show that the best ratio of substrate composition in biogas production is VW:CM 70:30 with a C/N ratio of 21.39% and produces 93.78% methane gas and produces a blue flame for 102.35 seconds.

Abstract

Leachate is a liquid containing extracted, dissolved, and suspended materials from waste in a landfill. Leachate from Klotok landfill contains pollutant loads that do not meet the water quality standards, necessitating treatment. In this study, parameters considered were COD, TSS, and TN. Anoxic-Oxic Moving Bed Biofilm Reactor (MBBR) was chosen due to its compact footprint, low sludge production, ability to handle high COD loads, and not requiring periodic backwash. Variations including media type, media volume, and Hydraulic Retention Time (HRT) were applied to reduce pollutant parameter concentrations. The experiment was conducted in batch-continuous mode. The derived parameter concentrations yielded promising results using a biocube/sponge media in the reactor, constituting 50% of the leachate volume, with an HRT of 45 hours. Upon continuous operation under the best variations for parameter reduction, COD, TSS, and TN values were achieved as 160 mg⁄L, 132  mg⁄L, and 31.5  mg⁄L, respectively. Meanwhile, the average removal percentages for COD, TSS, and TN were 87%, 50%, and 87% respectively. Additionally, microorganism identification was performed in the anoxic-oxic moving bed biofilm reactor, revealing the presence of microorganisms such as coliforms, Bacillus sp., and Pseudomonas sp.

Abstract

The importance of K3 aspects in docking activities not only includes individual safety, but also has a direct impact on productivity and operational continuity. Accidents or incidents that occur during the docking process can not only threaten the lives and health of workers, but can also cause detrimental environmental impacts and hinder the smooth running of the supply chain. The HIRARC method allows identifying various potential hazards that may be associated with an activity or work environment. This approach involves data collection, situational analysis, and determining appropriate mitigation measures. From the results of the identification carried out during ship docking activities at PT. Pelindo Marine Service has 14 activities that have potential danger. With 4 activities that have very low risk, namely maintenance and repair activities in the engine room, ship maintenance in closed rooms, maintenance and repairs in the electrical room, and manual lifting of heavy materials. Then there are 5 activities with low risk, including welding process activities in open spaces, carrying out repair work at height, operating cranes, cleaning ship rooms, and plate cutting (LPG gas cutting) and material grinding processes. 3 activities with medium/medium risk, namely working around waters, working/standing around ships, and stuffing/stripping activities. And there is 1 activity with high risk, namely the ship maintenance process using the welding process in a closed space and 1 activity with very high risk, namely the activity of filling gas cylinders (for cutting and welding equipment). The risks faced include slipping, falling, scratches, shortness of breath, weakness, eye irritation, injuries, minor injuries, serious injuries, sprains, burns, fractures, electrocution and others. And the efforts made to control the risks above include using Personal Protective Equipment with discipline, working according to SOPs, installing K3 signs, providing fire extinguishers, regular inspections and implementing a good ventilation system. Based on the results of risk identification in ship docking activities at PT. Pelindo Marine Services.
