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.

Public health center is responsible for carrying out comprehensive health services to the community in a certain work area. However, in an effort to implement it, Public health center can produce waste in the form of waste that is harmful to health. This review was conducted to analyze the management pattern of hazardous solid waste in Public health center in Kapuas Regency in accordance with the standards set out in the Peraturan Menteri Lingkungan Hidup dan Kehutanan Nomor 56 Tahun 2015. The results showed that the generation of hazardous solid waste of Public health center in Kapuas Regency has an average weight of 0.99 kg/puskesmas/day and a volume of 11.51 liters/puskesmas/day. The composition of the most waste produced by infectious waste is 40.23%. Meanwhile, the pattern of B3 solid waste management of Public health center in Kapuas Regency includes sorting, renting, collecting, moving, temporary storage and destruction, there are still many shortcomings that need to be addressed.

EVALUATION OF PARTIAL POOL AND THE INFLUENCE TIDAL FORCE APPLICATION BASED ON CIRCULATION PATTERN, AGE OF WATER, DISSOLVED IRON (Fe) and TSS AT RECLAMATION UNIT OF TERANTANG, TERANTANG VILLAGE, BARITO KUALA REGENCY, SOUTH BORNEO

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.

Study of Hazardous and Toxic Waste (B3) Waste Oil and Used Oil Contaminated Waste in Motorcycle Workshops in Banjarbaru City

Tue, 15 Apr 2025 00:00:00 +0800

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.

and, at DESIGN OF A REDUCE-REUSE-RECYCLE DUMPSTER (TPS 3R) IN KUIN CERUCUK BANJARMASIN CITY

Waste is a problem that is often experienced in urban areas, including the City of Banjarmasin. In big cities, waste is a problem both in terms of quantity and type. The size of the waste problem grows along with the growth of the population in the city. The increase in population causes an increase in population activity which also means an increase in the amount of waste generation. Hoarding is one of the most common ways of disposing of municipal solid waste. As happened in Kuin Cerucuk Village, Banjarmasin City which has a population of 19 467 people with a population density of 11,727.11 people/km2. As an effort to overcome the problem of waste generation in Kuin Cerucuk Village is to plan a TPS 3R. In making a waste building design, it is necessary to have both population projections and waste generation projections. From the results of the design of the buildings contained in the TPS 3R in the form of a receiving area, inorganic room (sorting area, plastic waste reception area, processed plastic waste reception area, milling area and washing area), inorganic room (organic reception area, enumeration area, composting area and sieving area), warehouse buildings, and supporting facilities (offices, toilets, prayer rooms and ablution areas). The land requirement for this design is an area of 1,110 m² with a Budget Plan of Rp. 3,017,465,295.09.

Syifa Yulia Hidayati, Muhammad Syahirul Alim — Tue, 15 Apr 2025 00:00:00 +0800

Coal wastewater can be treated by electrocoagulation method, is wastewater treatment using direct electricity and electrodes Aluminum (Al) plates. An analysis of the results of the quality test of coal effluent was carried out after the electrocoagulation method was carried out in meeting environmental quality standards according to the Peraturan Gubernur Kalimantan Selatan No. 36 Tahun 2008 tentang Baku Mutu Air Limbah Batubara and analysis of the effect of the contact time used, namely 30, 45, 60, 75 and 90 minutes. The research method used is the experimental method. The parameters tested were Total Suspended Solid (TSS), pH, iron (Fe) and manganese (Mn) and the distance between the electrode plates was 1 cm. The voltage used 12 volts. The results showed that at a contact time of 90 minutes the electrocoagulation process was effective in reducing contaminants so that it met quality standards, the TSS parameter value of efficiency reached 99.97% with a decrease in levels from 4305 mg/L to 1.33 mg/L, on the parameter pH increased from 5.37 to 7.27, in the iron (Fe) parameter the efficiency value reached 99.96% with a decrease in levels from 53 mg/L to 0.02 mg/L and the manganese (Mn) value efficiency reached 99.81% with a decrease in levels from 20.32 mg/L to 0.039%.
