Abstract

The Sustainable Development Goals (SDGs), point 6, has the objective of ensuring access to clean water and sanitation. The planning of a drinking water treatment plant is an essential component of achieving Target 6.1, which aims to provide safe and affordable drinking water for all by 2030. However, the Pangalengan subdistrict in Bandung Regency is confronted with a significant challenge, as 56.67% of cattle farmers are engaged in the discharge of livestock waste into the Cisangkuy River. It is therefore imperative to plan the construction of a drinking water treatment plant in the Pangalengan subdistrict. The research method commences with a comparison of the results of raw water tests conducted on the Cisangkuy River, which are then contrasted with the stipulations set forth in Health Minister Regulation No. 2 of 2023. Subsequently, a population projection is conducted in order to ascertain the projected water demand. The projected water demand is 371.92 liters per second in 2032. Subsequently, the selection of treatment units is conducted using the Likert scale method. The analysis yielded the conclusion that the quality standards are exceeded by the parameters turbidity and coliform. The alternative units employed are the intake, barscreen, coagulation and flocculation, sedimentation, filtration, disinfection, and reservoir units.

Abstract

Flooding is one of the natural disasters that frequently occur in Indonesia, especially in Bandung Regency, which is often affected by flooding due to river basins that cannot accommodate excess water. To address this problem, an Internet of Things (IoT)-based flood early warning system (FEWS) has been developed that can monitor river water levels and provide early notification to the public via the WhatsApp application. This study aims to design and test a user interface integrated with the FEWS system using ThingSpeak as the database and WhatsApp as the notification application. The methods used include data collection, requirements analysis, design, implementation, and system testing. The test results show that ThingSpeak is able to upload water level data in real time with an average delay of 11.5 seconds, and WhatsApp successfully sends water level category notifications to users in a timely manner. In conclusion, the developed system successfully provides accurate information and appropriate notifications to help the public take early evacuation steps during floods.

Abstract

The generation of waste in landfills can result in the production of wastewater, commonly referred to as leachate. This leachate has the potential to pollute the surrounding environment, as it can enter the groundwater or be transported by surface flows. Consequently, leachate treatment is conducted through a two-stage anaerobic process. The method was selected due to its capacity to decompose waste with high organic content and to produce optimal biogas. The objective of this study is to ascertain the impact of employing a two-stage anaerobic bioreactor on the proliferation of anaerobic microorganisms in the context of leachate treatment. The application of an acidic pH in the acidogenic bioreactor influences the growth of acidogenic bacteria, resulting in a shorter lag phase in comparison to the single bioreactor. This also impacted the reactor's performance in reducing the concentration of chemical oxygen demand (COD). The two-stage bioreactor demonstrated a superior COD reduction efficiency of 78%, in comparison to the single-stage bioreactor, which exhibited an efficiency of 69%.

Abstract

One of the areas that can be mined for minerals in the form of igneous rocks, such as andesite and basalt, is Siulak Deras Village in Gunung Kerinci Regency, Jambi Province. These rocks are composed of rock minerals and thus do not require international sale. Mining is a relatively straightforward process that does not necessitate the use of sophisticated technology, as it is conducted at the surface. The objective of this research is to gain insight into the distribution of igneous rocks in order to facilitate the interpretation of rock reserves and deposits through the application of the geoelectric resistivity method. The study commenced with the mapping of the geological features pertinent to the excavation of igneous rocks, followed by the planned collection of geoelectrical data utilising a four-track Wenner configuration, with a track length of 240 metres and a track distance of 10 metres. The resistance values thus obtained should be converted into a two-dimensional cross-sectional view. The findings of this research indicate that the area exhibits potential for the presence of igneous rock, as evidenced by resistance values exceeding 2500 Ωm. The distribution of subsurface igneous rocks based on resistivity is thought to occur randomly, as evidenced by geoelectric lines. However, the numbers are very large. The data processing results indicate that the igneous rocks in this area are the result of volcanic activity rather than magma intrusion.

Abstract

A product defect is defined as a problem related to the quality of the product. The company will endeavor to minimize the occurrence of defective products in order to enhance its overall productivity. The total production of Dripper 1 in the period between May 2023 and May 2024 amounted to 4,227 units, with a defect rate of 22.7%. The proportion of defective products has exceeded the permitted tolerance limit of 5%, necessitating the implementation of quality control measures through the introduction of improvements to the production process. The most appropriate method for improvement is the TRIZ method, as it is designed to facilitate the generation of creative solutions. However, the solutions provided are merely alternative solutions; thus, the ANP method is necessary to determine which alternative is the most optimal. The production of Dripper 1 is characterized by eight distinct types of defects, namely black dot defects, flow marks, scratches, silver marks, burn marks, discoloration, bubbles, and brass flakes. Among these eight types of defects, black dot defects, flow marks, and scratches are the most prevalent, with respective frequencies of 449, 237, and 114 units. The alternatives resulting from the TRIZ method include the installation of filters, periodic machine cleaning, the design of auxiliary tools, modifications to gate sizes, periodic inspections, the creation of standard operating procedures (SOPs), and operator training. According to the ANP method, the alternative with the highest weight is the installation of filters, with a value of 0.29177 (29.177%), and is therefore selected as the solution to the problem.

Abstract

The increasing demand for paper products over time has led to a corresponding increase in the amount of paper waste generated. Andalas University Campus endorses the recycling concept through the establishment of an Integrated Waste Management Center (PPST), which encompasses the Andalas Enviro Waste Bank (BSEA). This center is designed to oversee the management of dry waste that is suitable for sale, with the proceeds from such sales being directed to third parties. This study examines the optimization of paper waste utilization at the Andalas University Campus in Limau Manis, Padang. The study referenced data on the generation, composition, and recycling potential of paper waste from the Unand campus, as well as existing conditions of paper waste management at each source, obtained through the distribution of questionnaires and interviews. The results of the calculations demonstrate that the quantity of paper waste suitable for sale on the Unand campus is 779.82 kg/day. The BSEA is responsible for the collection of this waste through the waste bank system. The study was conducted by creating three scenarios for the management of paper waste: (I) direct sales of paper waste without processing; (II) processing of cardboard waste into egg containers and other types of paper waste into recycled paper; and (III) processing of HVS paper waste and selling other paper waste. The results of the assessment, conducted using incremental IRR analysis and scoring methods, indicated that scenario III was the optimal management scenario for optimizing the utilization of marketable paper waste at the Andalas University Limau Manis Campus from a technical and financial perspective.

Abstract

Poly Aluminum Chloride (PAC) is a chemical that is frequently utilized in the treatment of drinking water. It is therefore essential to investigate methods of reducing the dosage of PAC in conjunction with natural ingredients that have the potential to adsorb pollutants in water. This research employs a combination of PAC and aloe vera, utilizing the optimal composition identified in previous research. The research was conducted on a laboratory scale using raw water samples of river water that had been intentionally contaminated with iron. The pollutant parameters measured were iron, organic matter, and ammonia. These parameters were selected as they are likely to be affected by the addition of aloe vera. The results of the treatment using jar tests were evaluated by comparing the quality of the initial water sample, the use of PAC alone, and the use of a combination of PAC and aloe vera. The experimental results demonstrated that the combination of PAC and Aloe vera exhibited superior efficacy in reducing iron levels compared to PAC alone. However, this combination also resulted in a notable increase in organic matter levels in the water samples.

Abstract

The coagulation and flocculation processing units represent a series of processing units that employ physical and chemical methods. The objective of this research is to ascertain the impact of coagulant type on process parameters, including turbidity, TSS, and pH, within the coagulation-flocculation processing unit integrated within the WWTP system. This research employs the use of raw water in the form of an artificial wastewater with characteristics closely resembling those of domestic wastewater, with a particular focus on process parameters such as turbidity, total suspended solids (TSS), and pH. The coagulants employed in the coagulation process are polyaluminum chloride (PAC) and aluminum sulfate/alum (Al₂(SO₄)₃.18H₂O). The operation of the wastewater treatment plant (WWTP) is conducted with a coagulation stirring speed of 150 rpm, while flocculation is performed at 60 rpm. A jar test was conducted to ascertain the optimal dose and pH of the coagulant. The results demonstrated that the optimal dose of PAC was 50 ppm, with an optimal pH of 7. In contrast, the optimal dose of alum was 60 ppm, with an optimal pH of 8. The findings revealed that the dose obtained through the implementation of the jar test in the WWTP unit with a stirring speed of 150 rpm yielded the most effective PAC coagulant results, with a TSS value of 10.53 mg/L, turbidity of 4.01 NTU, and pH of 6.74, accompanied by a TSS efficiency value of 94.86%. The velocity gradient and residence time in the coagulation and flocculation units do not align with the specified design criteria. However, both the residence time and overflow rate in the sedimentation unit meet the prescribed design criteria.
