: Liquid organic fertilizer is a fertilizer that is available in liquid form. This liquid organic fertilizer can be made naturally through a fermentation process to produce a solution of decay from plant residues. Liquid organic fertilizer is better to use because it is free from chemicals and has a good impact on health. The purpose of this research is to study the manufacturing technique and to determine the physical and chemical properties of liquid organic fertilizer from tofu liquid waste with banana hump mole decomposer. The research method is experimental. The results obtained are the quality of the physical properties of liquid organic fertilizer from tofu liquid waste with banana hump Mol with an average temperature from 26 to 29 o C, yellow (8/8) 10YR color or reddish yellow, characteristic sour smell, and TSS 5132 – 5879 mg L -1 . The quality of the chemical properties of liquid organic fertilizers are the average pH 3.62 – 3.72: Nitrogen 7.98 – 8.22%, Phosphor 0.002%, and Potassium 0.03%. The liquid organic fertilizer is under the standard of liquid organic fertilizer but the pH value is slightly lower than the standard.

Abstrak: 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.

: 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. A 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 level of pollution in the waters of the Teluk Sirih Steam Power Plant area is still low in the good category so it is still safe for marine biota

: The people of Palembang city during the covid-19 pandemic, which lasted for approximately three 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 SMsE Pempek of snakehead fish. Based on this condition, during the COVID-19 pandemic, there is a need for a strategy to strengthen SMEs that produce pempek of snakehead fish using a SWOT analysis. This research was carried out in the city of Palembang by taking samples 12 respondents at a SMEs Pempek Snakehead fish. This SMEs is located on Jl. Pakjo Palembang by consideration as one of the producers of snakehead fish pempek which is still active during the COVID-19 pandemic. In order to survive during the COVID-19 pandemic, SMEs Pempek Palembang must implement several targeted strategies, including improving services with 24-hour admin services via Whatsapp application (chat/phone) so that they can be ordered anytime, the order method made by order, creating 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 is relatively more stable. In addition, the government, especially the fisheries service, can encourage the community to be more active in cultivating snakehead fish.

. Giritengah catchment is 5 km to the southwest of Borobudur Temple and is an area that has been designated as a buffer zone that 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 predominant Erosion Hazard Levels is in the very low, low, and heavy classes. The application of the suitable SWC technique in the form of bench and ridge terrace’s 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.
. 吉里登加集水区位于婆罗浮屠寺西南5公里处,是一个被指定为缓冲区的地区,作为婆罗浮屠地区旅游活动的支持区。本研究的目的是预测吉里腾嘎流域的侵蚀,并为应用正确的水土保持技术来减少吉里腾嘎流域的侵蚀制定一个方案。利用水土评估工具(SWAT)模型进行侵蚀估算。结果表明:平均侵蚀量为30.7 t /ha/年,其中旱地侵蚀量最大;主要侵蚀危害等级分为极低、低和重三级。在台阶和山脊阶地结构中应用合适的SWC技术,有望将吉里吞加流域发生的侵蚀减少到极低的侵蚀危险等级(EHL)等级,达到总面积的60.4%,并消除严重的EHL等级。

: 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 in Tanjung Pasir 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. 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.
