Abstract

The quality of a watershed can be seen from the discharge of the river flow. Watershed quality can also be seen from the sedimentation found in river water flows and river bodies. Sedimentation is sediment produced by the erosion process carried by the flow and deposited in a place where the water velocity is smaller than the settling velocity. This research was conducted in the intake area of the Musi Hydroelectric Watershed, Ujan Mas District, Kepahiang Regency, Bengkulu Province in August – October 2022. This study used hydrographic and bathymetric survey methods. The results of research on sedimentation using bathymetric maps and the results of sub- bottom profiling in the intake corridor area of the Musi Hydroelectric Power Plant (up to approximately 500 m from the weir), it is known that an average thickness of 1.7 meters near the intake pond (south side) and is getting higher up to 2.5 meters thick to the north or upstream of the river. The thickness of the sediment tends to thicken towards the east or along the riverbank with an average thickness of 2 meters, while in the west it tends to be thinner, with an average of 1.8–2.0 meters. Based on the results of the grab sampler, the type of sediment layer is sandy silt.

Abstract

The central role of the Citarum River as a buffer to meet the needs of agricultural irrigation, industrial activities, and raw water in the six surrounding districts, including 80% of the population of Jakarta, has experienced a decline in conditions from up-downstream. That way, a lot of data is available regarding the adaptation of floods, drought, and other water source functions for an integrated concept for Citarum. The focus of the study is in the Central Citarum Zone by using 5 and 10 years of rainfall intensity (time series), actualizing the runoff coefficient, Intensity Duration Frequency (IDF) modeling to the formulation of the peak runoff discharge. This achievement is realized by applying Gumbel's Method and Mononobe's Equation and optimizing the 2D HEC-RAS software. Experimental data from 2010 to 2019 indicated that November was the highest rainfall of 448.07 mm/hour, while the lowest was in July with a value of 52.50 mm/hour. The simulation results show an increase in flow rate up to 11%, which means it affects the river's capacity to accommodate the overflow load. Furthermore, this simulation is equipped with a map of the flood-affected areas with a peak discharge scenario in November.

Abstract

Tarakan City is a city that has potential natural resources to be developed. One of the areas in the town of Tarakan is Tanjung Pasir, where the residents live in the coastal area. This study aims to determine the quality of the waters of the dune by using the plankton community structure as a water bioindicator. As a research object, Plankton communities in Tanjung Pasir waters include abundance, diversity index, uniformity index, and dominance index. This study uses a quantitative descriptive method with the research location being carried out at two points, namely Station I in the mangrove area and Station II close to residential areas. Sampling was conducted every two days, 15 times out in the field. The types of phytoplankton found in five classes, namely Bacillariophyceae, Coscinodiscophyceae, Cyanophyceae, Mediophyceae, and Dinophycea lessons and zooplankton from Crustacea class at Station I and Station II. Station I and Station II were from classes. The most abundant types of phytoplankton are found in Bacillariophyceae and Dinophyceae because these two classes dominate all kinds of phytoplankton worldwide. The abundance value of phytoplankton at; Station I was 354 cells/l; at Station II, it was 202 cells/l. The abundance of zooplankton at; Station I was 40 ind/l, and at Station, II was 38 ind/l. The diversity index at the two stations is in the medium category, with the uniformity index being in the high uniformity category and the dominance index at each low. Based on the value of the plankton community structure, Tanjung Pasir waters are classified as lightly polluted. Environmental factors of Tanjung Pasir waters in Tarakan city include the physical and chemical characteristics of Station I and Station II, which are still suitable for the life of aquatic organisms.

Abstract

Giritengah catchment is 5 km to the southwest of Borobudur Temple and is an area that has been designated as a buffer zone which acts as a support zone for tourism activities in the Borobudur Area. The purpose of this study is to predict erosion in the Giritengah catchment and develop a scenario for the application of the right Soil and Water Conservation (SWC) techniques to reduce erosion in the Giritengah catchment. Erosion estimation is carried out using the Soil and Water Assessment Tool (SWAT) model. The results showed  that the average amount of erosion is 30.7 tons/ha/year with the highest average erosion being on dry land use. The classification of the predominant Erosion Hazard Level is in the very low, low and heavy classes. The application of the right SWC technique in the form of bench and ridge terraces structure is expected to be able to reduce erosion that occurs in the Giritengah catchment to very low Erosion Hazard Level (EHL) classes reaching 60.4% of the total area and eliminate heavy EHL classes.

Abstract

The people of Palembang city during the covid-19 pandemic which lasted for approximately 3 years tended to be more selective in buying products, one of which was the most popular Palembang food, namely pempek. The Covid-19 pandemic has also brought significant changes for Small and Medium Enterprises or SMEs in Palembang City. Many SME players have experienced a decline in sales since this pandemic, one of which is the SME Pempek of snakehead fish. Seeing this condition, there is a need for a strategy to strengthen Pempek Gabus Palembang Small and Medium Enterprises during the COVID-19 pandemic using a SWOT analysis. This research was carried out in the city of Palembang by taking samples of the UKM Pempek Ikan Gabus. Research SMEs are Small and Medium Enterprises with 12 respondents whose central location is on Jl. Pakjo Palembang with the consideration that this UKM is one of the producers of cork fish pempek which is still active during the COVID-19 pandemic. Pempek Palembang UKM in order to survive during the COVID-19 pandemic must implement several targeted strategies, including: improving services with 24-hour admin services via wa (chat/phone) so that they can be ordered anytime, the order method made by order, Creating new innovations by using shuji/pandan leaves as a natural dye for pempek and minimizing the fishy smell of fish, making an MoU to snakehead fish farmers so that the availability of raw materials is guaranteed and the price of clothing materials is relatively more stable. In addition, the government, especially the fisheries service, can encourage the community to be more active in cultivating snakehead fish.

Abstract

The waste sector is one of the largest contributors to greenhouse gas (GHG) emissions in Indonesia. Landfilling (without methane recovery) and open burning of solid waste contribute significantly to GHG emissions. This study analyses the magnitude of GHG emissions from various municipal solid waste management (MSW) alternatives in Palembang city. The estimation of GHG emissions was conducted for five waste management scenarios, i.e. (a) BAU scenario (existing) where 850.12 tonnes of MSW is disposed in semi-aerobic landfill (not well managed), 37.73% in open incinerators, 1.17% in 3R facilities, and 61.1% others; (b) Scenario 1, in which the landfill is upgraded to a semi-aerobic (well managed); (c) Scenario 3, in which 70% of MSW is disposed in semi-aerobic (well managed) and 30% is disposed in 3R facilities; and (e) Scenario 4, in which all collected MSW is treated in incinerators. The methodology for estimating GHG emissions used IPCC 2006 (revised 2019). The Emission Quantification Tool from IGES is used to calculate GHG emissions from collection, transportation, composting, recycling/upcycling, and final disposal (landfill or incineration). The scenario is projected up to the year 2030, in accordance with the Indonesian NDC. The result of the analysis shows that the existing condition (BAU) has the highest GHGs emissions (730,767 tonnes CO2e). Scenario -4 has the lowest GHG emissions (117,954 tonnes CO2e). Therefore, 3R activities are the most important success factor for reducing GHG emissions in the MSW sector. Further financial analysis studies and multi-stakeholder engagement are needed for these scenarios to plan for sustainable MSW management.

Abstract

The existence of the Electric Steam Power Plant (ESPP) in Teluk Sirih located on the seafront will certainly have an impact on changes in environmental factors such as physical, chemical and biological factors, because the water needed for the ESPP operational process comes from sea water. Changes in the physicochemical factors of sea surface water due to ESPP activity will affect organisms in these waters, one of which is phytoplankton. Therefore, the purpose of this research is to look at changes or trends in the phytoplankton community and its relation to pollution by the physics and chemistry of the waters around the ESPP Teluk Sirih. This research was conducted from June 2019 to June 2021, sampling was carried out annually for three years. This study used a purposive sampling method and plankton sampling using a plankton net horizontally, then the samples were taken to the laboratory for identification. Sampling of water physics and chemistry was carried out in situ and ex-situ, namely by being preserved for further transport to the laboratory. The results of this study indicate the trend of phytoplankton fluctuating from the number of abundance, taxa and diversity index. This is because the physicochemical factor also fluctuates, there is one parameter above the quality standard, namely phenol whose levels are more than 0.02 mg/l. However, it can be concluded that the condition of the waters in the ESPP Teluk Sirih is still in quite good condition.

Abstract

Regulation of the Minister of Environment and Forestry of the Republic of Indonesia No. 4 of 2021: All types of businesses and activities must manage environmental impacts. Emissions resulting from the use of heavy equipment in the operational activities of the coal mining industry, such as scrapers, dump trucks, loaders, excavators and bulldozers. In addition to heavy equipment, exhaust emissions are generated from the use of generators that operate longer than 1,000 hours per year. The resulting emissions will have a long-term impact on air quality around business activities [1]. In an effort to tackle the spread of air pollution, modeling is carried out which aims to analyze emission air dispersion patterns by measuring exhaust emissions with Nitrogen Dioxide (NOx) and Carbon Monoxide (CO) test parameters in industrial activity areas with AERMOD applications and can predict emission air dispersion patterns dispersed into the air based on the distance and concentration of particles. One of the models used is the Gaussian Plume Model. Modeling is done by processing data from the meteorological section with AERMOD software, which will then provide a distribution pattern with a distribution pattern that is close to the true value [2]. Modeling is carried out with a radius of 5,000 meters and data from emission measurements from the power generation unit. Based on the modeling results, the CO parameter emission dispersion obtained the highest value in February with a value of 30.4 µq/m3 and the lowest value in March with a value of 3.43 µq/m3. As for the NOx parameter, the highest dispersion value was in June at 6.21 µq/m3, and the lowest value was in January at 3.51 µq/m3. This research was conducted in March 2023. It is located on the project site of the Coal Mining Industry area with a mining business permit (IUP) area of 2936.14 ha in Mekar Jadi Village, Sungai Lilin District, Musi Banyuasin Regency, South Sumatra Province.
