Abstract

The presence of antibiotics in aquatic environments has been known to lead to the development of bacteria with resistant genes. One type of antibiotic that has been found in the environment is trimethoprim, necessitating methods to remove this substance from the environment. Adsorption is a process that has been extensively studied in the field of water remediation. This study aims to investigate the adsorption of trimethoprim by granular activated carbon (GAC). Experiments were conducted by creating artificial wastewater containing distilled water and trimethoprim, which was then contacted with the adsorbent with variations in pH and trimethoprim concentration measured periodically up to the 3rd hour. Trimethoprim detection was performed using a UV-Vis spectrophotometer. The contact time required to reach equilibrium increased with the initial concentration of trimethoprim. The variations in initial trimethoprim concentrations of 5, 10, 20, 35, and 50 mg/L reached adsorption equilibrium after a contact time of 180 minutes with a GAC mass of 3 grams. All the percentages of trimethoprim removal after the contact time of 180 minutes at various concentrations used in this study were above 98%. The pH level has been proven to affect the trimethoprim removal process. The pseudo-second-order kinetic model has a high correlation with the adsorption process of trimethoprim by GAC. The isotherm model suitable for the interaction between trimethoprim and GAC was the Freundlich model.

Abstract

Home industry is a type of SME (Small and Medium Enterprise) that can promote community self-reliance and boost Indonesia's economic growth. NK Bread Home Industry produces various types of bread, including white bread, gembul bread and sweet bread. This home-based industry uses a make-to-order production system, with production levels based on orders. In order to anticipate fluctuations in demand, this industry also maintains stocks. The main problem for this cottage industry is the lack of accuracy in inventory planning due to the lack of demand forecasting. As a result, production is based on experience. In addition, production output is not maximised due to the lack of production capacity planning. This research aims to plan production capacity using the RCCP (Rough-Cut Capacity Planning) method with the BOLA (Bill of Labor Approach). The results obtained show that the required capacity is 1878.50 units, which is greater than the available capacity of 1417.26 units per period. In order to solve this problem, recommendations are made, such as the need to increase the number of workers, the number of machines, the adjustment of the production rate and the use of subcontracting. With these suggestions, it is expected that the production house will be able to maximise capacity, leading to an increase in production output.

Abstract

The landfill problem caused by plastic glass water bottle waste has become a serious concern in the last decade. The right processing process can be a solution to these problems, especially in the process of separating plastic glass components. The purpose of this study is to prioritise the main material alternatives used in the plastic glass ring cutter. The required material selection criteria consist of four, namely: material strength, material weight, environmental resistance and cost of raw materials and manufacturing processes. The specified material alternatives are: mild steel (SS41), aluminium and polymer (nylon). Based on the weighting determined by the experts and data processing using the AHP method, the first priority alternative material is aluminium with a value of 0.432 or 43.2%, the second is mild steel (SS41) with a value of 0.367 or 36.7% and the third is polymer (nylon) with a value of 0.201 or 36.7%. Based on these results, the main priority for the use of alternative materials in the AMDK plastic glass ring cutting tool is aluminium.

Abstract

The Karang Anyar Road - PTPN VII Trikora Anyar Road in South Lampung does not have adequate facilities. There are no street lights and road markings are not clearly visible. This situation can endanger the safety of drivers. In this study, the evaluation conducted includes evaluation of traffic speed and adequacy of road facilities to minimise traffic accidents. The research method broadly includes preparation, literature review and site identification, followed by conducting the research, namely speed and road facility adequacy surveys. The results of the survey on signs and markings in the current conditions show a lack of road facilities, including the absence of traffic lights and road control and safety devices. Other facilities such as warning signs are present. Street lighting is still inadequate as it is only present at a few points and does not provide adequate lighting for the Karang Anyar Road - PTPN VII Trikora Anyar Road in South Lampung. Vehicle speed shows that the speeds of vehicles passing through Karang Anyar Road are as follows: Light Vehicles (LV) at 27.69 km/h, Heavy Vehicles (HV) at 20.69 km/h, and Motorcycles (MC) at 40.67 km/h.

Abstract

The city of Surabaya is located downstream of the Brantas River, which is an area of overflow from passing rivers, making it prone to flooding during the rainy season. Climate change is the occurrence of changes in climate components due to global warming. The vulnerability of RW 01 Banjar Sugihan is facing the problem of flooding from other higher areas. The aim of this research is to analyse the duration of rainwater infiltration and also to calculate water infiltration in flood prone areas. Biopore absorption holes (LRB) are a suitable technology that is easy to implement, cheap and environmentally friendly. Rainwater infiltration can be calculated using water infiltration through biopore holes. The results of the water infiltration calculations show that the total volume of rainwater infiltration increases with the increase in the number of biopore infiltration holes each year, until in 2024, with a total of 86 biopore infiltration holes, the volume of rainwater infiltration is 0.47 litres/second.

Abstract

PT HMG is a manufacturing company that uses injection moulding machines to produce plastic components for the electronics, automotive and engineering industries. The problems found at PT HMG are that the finished goods are not placed in an orderly manner or that the goods are not neatly arranged. The placement of these goods is still mixed with goods that have run out, so the process of moving goods is not optimal and the risk of picking inappropriate goods is higher. This has an impact on delivery errors and the sub-optimal process of moving goods can cause delays in delivery to the customer. Dedicated storage is a layout design method for storing goods where the storage location is fixed. This method uses throughput as areference when positioning goods so that goods with a high flow of movement are prioritised to minimise the time it takes to move goods to I/O points. The difference in the total distance to the I/O point for the proposed layout is 17,809 metres, or 9% of the previous layout. With this layout improvement, the company is able to reduce the waste caused by material handling activities in the finished goods warehouse.

Abstract

The pollution of rivers by domestic waste has become a serious problem affecting water quality. To address this problem, the use of ecoenzymes has been proposed as a solution for domestic waste treatment. In this study, different concentrations of ecoenzymes (10%, 20%, 25%) in the anaerobic process and retention time (2, 4, 6 days) were used to measure the degradation of organic parameters such as TSS (Total Suspended Solids), surfactants and phosphates. The results of the study indicate a significant reduction in TSS, surfactants and phosphates. The optimum concentration for TSS reduction was found to be 10%, while for surfactants and phosphates it was 25%. The optimum retention time for all parameters was found to be 6 days. These results provide an effective and economical solution for reducing river water pollution caused by domestic waste. It is hoped that the results of this study will provide another option for the treatment of domestic wastewater and the maintenance of river water quality.

Abstract

Many large cities in Indonesia, including Surabaya, face major problems with urban waste management. One way to reduce the amount of waste generated is through the Zero Waste Village programme. This programme is an initiative of the city government of Surabaya with the aim of reducing waste and raising public awareness about waste management. The methods used are observation and interviews. The results of the implementation showed a decrease in the amount of waste in two regions. The success is supported by the active participation of the citizens. However, obstacles were also identified in the management of organic waste and in the extensive territorial and infrastructural constraints that support the programme's activities.
