Abstract

Tofu is a soy-based culinary product. During the manufacturing process, the tofu industry generates solid refuse and liquid waste. The majority of the tofu industry lacks a sewage treatment infrastructure, so the resulting waste is discharged directly into the river. High levels of organic pollutants are present in liquid waste, which can cause significant pollution. The effluents discharged into the water must meet the established quality requirements. If the water discharged does not meet quality standards, it will pollute the environment. This research aims to evaluate the quality of wastewater produced by the tofu industry, as well as determine the most suitable treatment technology for the waste conditions and design a wastewater treatment plant (WWTP). The tofu industry's liquid effluent contains 2666.5 mg/L BOD, 12476.1 mg/L COD, and 3220.3 mg/L TSS. The selection of WWTP technology utilizes a scoring method based on criteria provided by the Technical Team for Sanitation Development. The chosen treatment unit is an Anaerobic-Aerobic Biofilter with a score of 4.3. The design of the WWTP model includes an equalization tank, initial sedimentation tank, anaerobic biofilter tank, aerobic biofilter tank, and final sedimentation tank.

Abstract

Because the capacity of natural or man-made channels can no longer support the flow of incoming rains, inundation may happen. Nearly every puddle in Cempaka District, with an average height of 20 cm and an inundation time of 6 hours or until the rain stops, is in a residential area, a rice field, or a plantation, according to the final report of the 2021 Banjarbaru City Environmental Road Drainage Masterplan. The goal of this plan is to study the anticipated flood flow, assess the drainage channel's capacity, suggest infiltration well proportions, and create a three-dimensional layout of the infiltration wells. With maximum daily rainfall data for 10 years (2012-2021), hydrological and hydraulic analysis was conducted for this design. According to the findings of the anticipated flood discharge calculation, segment 1 will experience a minimum discharge of 0.06 m3/s and a maximum discharge of 0.19 m3/s. This planning makes use of the Storm Water Management Model (SWMM) software, which enables modeling of the field's current drainage conditions by adding metrics collected under real circumstances. It is advised to include infiltration wells with a 1 m diameter and a 3 m well depth. To avoid flooding, infiltration wells will be installed to each section to lessen the projected flood flow that will enter the drainage canal and reach the water body.

Abstract

Waste is the rest of human daily activities and / or natural processes in solid form. Waste can have a very bad impact on people's health and environment if it cannot be addressed. The waste problem must be handled appropriately. One alternative to improving waste management is by replacing or implementing an existing waste treatment site with a 3R (reduce, reuse, and recycle) based waste treatment site. The amount of waste generation is directly proportional to population growth. North Banjarbaru is one of the sub-districts in Banjarbaru City with an area of 26,855 km2. North Banjarbaru District has a population of 53,770 people (as of 2021) and has a population growth rate of 1.31% annually, North Banjarbaru is the district with the densest population density of 2,162 people/km2. The data processing method used in planning consists of site selection, population projection calculation, waste generation calculation, mass balance calculation, land/space needs calculation, and 3R TPS floor plan layout. The logarithmic method is used for the calculation of population projections and waste generation in TPS 3R planning because it has the best correlation coefficient value and standard deviation. The total population of waste generation in the planning year (2031) is 65.595 people and 28,206 tons/day. The planning location is located on Jl. Pd. Sejahtera, North Loktabat Village. The land area required for this plan is 365.3 m2. Keyword: waste, population, waste generation, TPS 3R planning

Abstract

Water is one of the crucial factors determining the basic needs of human life on Earth. The increasing demand for drinking water, if not accompanied by an increase in its production capacity, can lead to issues in service provision. PTAM Bandarmasih is a government institution responsible for providing clean water for the residents of Banjarmasin city. The objective of this research is to analyze the pH, turbidity, and distance of clean water related to residual chlorine in the distribution pipeline network within the customers' houses in IPA 1 A.Yani PTAM Bandarmasih Zone West Banjarmasin. This study is an analytical observational research using survey methods. A total of 30 water quality samples were taken from different locations, each representing a District Meter Area (DMA) block in the West Banjarmasin Zone. The data analysis employed univariate and bivariate analyses using Pearson correlation and Spearman Rank correlation. This method involved measuring all relevant variables and then conducting statistical analysis to observe the relationships between these variables. The research findings indicate that the average pH in the distribution water of IPA 1 A.Yani PTAM Bandarmasih is 7, with an average turbidity of 3.41 NTU. The average distance between customers' houses and IPA 1 A.Yani is 4.7 km. The analysis reveals strong correlations: pH with a correlation of -0.767, turbidity with a correlation of -0.779. The parameter most strongly related to residual chlorine value is the distance, with a very strong correlation of -0.850.

Abstract

Since the communal WWTP of Banjarbaru was operated in 2012, no evaluation has been conducted to assess the performance of the communal WWTP. The evaluation was conducted to determine the ability of the WWTP and to analyze various problems that caused the wastewater to not meet the quality standards from a technical and non-technical perspective. The methods used in this study were observation, literature study, laboratory tests, interviews, and questionnaires. Sampling locations are at the communal WWTP inlet and outlet. The results of the questionnaire were processed by scoring using a Likert scale. The results showed that the performance of communal WWTP in Banjarbaru based on technical aspects was classified into category A (good), operational and maintenance aspects, as well as financial aspects, were included in category B (good enough), and institutional aspects were included in category C (not good). Based on the results of the assessment, it is known that the performance of the Banjarbaru communal WWTP is not optimal and needs to be improved in several aspects.

Abstract

Swamp land in Terantang Village, Barito Kuala Regency, South Kalimantan has the potential to be utilized if managed optimally. Sour swamp land needs to be managed by the reclamation process. However, the high accumulation of toxic iron (Fe) becomes an obstacle in optimizing the reclamation process. The two-way flow system with the help of tidal ponds in the reclamation channel used still needs further evaluation to find out how effective the washing of toxic materials is. The main factors that influence the most are tidal events and partial pond function. The use of Environmental Fluids Dynamic Code (EFDC) software with simulation based on the data obtained is estimated to be able to solve the existing problems. This research was conducted in primary, secondary and tertiary reclamation channels with several stages. The first stage is to identify the hydrodynamic conditions and water quality in the Terantang unit reclamation channel. The second stage is the preparation and testing of the model. The second stage is the preparation and testing of the model. The last stage is model simulation on flow pattern, water age, accumulation of iron (Fe) concentration and accumulation of TSS concentration in 3 scenarios. The scenarios consist of simulating the hydrodynamic aspects of current movement and water age and 2 simulation scenarios of the water quality aspect on the accumulation of iron (Fe) concentration and TSS concentration by paying attention to the partition coefficient and without the partition coefficient. Simulations were carried out using the primary, secondary and 5 tertiary channel representative model data. The simulation results show that the application of channel tidal forces and partial pool utilization is still not running well. This happened based on the simulation results on the hydrodynamic and water quality aspects, showing that the water washing process still reached 60% with the water age reaching 3 days. The tidal force of the water is not able to reach the end of the channel and the tide pattern has not yet reached the end of the channel but has receded.

Abstract

The number of uses of transportation equipment such as motorcycles continues to increase every day along with the number of populations that increases every year. Motorcycles are most often used by the community because motorcycles are quite affordable and more flexible for people with a high enough level of mobility. The increasing demand for motorcycles must be offset by the addition of services for these motorcycles such as workshops, where workshop activities produce waste in the form of hazardous and toxic materials (B3) waste such as used oil, used oil filters, used oil packaging bottles and also cloth contaminated by used oil. The purpose of the study is to identify the amount of B3 waste generation, management of packaging, storage/collection, and licensing and transportation of B3 waste. The calculation of B3 waste generation is carried out by taking sample data and questionnaires at each Type-B motorcycle workshop which amounts to 12 workshops and is carried out for 12 days. The average B3 waste generation per workshop at each Type-B motorcycle workshop in Banjarbaru City is for used oil accommodated as much as 8.24 liters/workshop/day, used oil filters as much as 0.40 pieces/workshops/day, waste washcloths/used fields as much as 2.53 sheets/workshops/day and used oil packaging as much as 15.33 bottles/workshops/day. B3 waste management at two-wheeled motorcycle workshops in Banjarbaru City has still not been by applicable regulations.
