: 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.
液体有机肥是一种以液体形式存在的肥料。这种液体有机肥料可以通过发酵过程自然制成,从植物残留物中产生腐烂的溶液。液态有机肥最好使用,因为它不含化学物质,对健康有很好的影响。本研究旨在研究利用香蕉驼峰鼹鼠分解器从豆腐废液中提取液体有机肥的生产工艺及理化性质的测定。研究方法是实验性的。结果表明,以香蕉驼峰Mol为原料的豆腐废液为原料,得到的液体有机肥的物理性能优良,平均温度为26 ~ 29℃,颜色为黄色(8/8)10YR或红黄色,有特有的酸味,TSS为5132 ~ 5879 mg L -1。液体有机肥化学性质的平均pH值为3.62 ~ 3.72,氮为7.98 ~ 8.22%,磷为0.002%,钾为0.03%。液体有机肥低于液体有机肥标准,但pH值略低于标准。

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.
摘要:一个流域的质量可以从河流的流量中看出。流域质量也可以从河流水流和河体的沉积中看出。泥沙是由水流携带的侵蚀过程产生的泥沙,沉积在水流速度小于沉降速度的地方。该研究于2022年8月至10月在明古鲁省Kepahiang县Ujan Mas区Musi水电流域取水区进行。本研究采用了水文测量和水深测量方法。根据木寺水电站进水口廊道区域(距堰约500米)的测深图及亚底剖面沉降研究结果可知,进水口(南侧)附近的平均厚度为1.7米,向北或上游的平均厚度为2.5米。沉积物的厚度向东或沿河岸呈增厚趋势,平均厚度为2米,向西呈变薄趋势,平均厚度为1.8-2.0米。根据抓斗取样器的结果,沉积物层类型为砂质淤泥。

: 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
:电蒸汽发电厂(ESPP)的存在定会对环境因素的变化产生影响,如物理、化学和生物因素,因为电蒸汽发电厂运行过程所需的水来自海水。由于ESPP活性引起的海洋表层水体理化因子的变化会影响到这些水域的生物,其中之一就是浮游植物。因此,本研究的目的是观察浮游植物群落的变化或趋势,以及它与污染的关系,通过ESPP周边水域的物理和化学。本研究于2019年6月至2021年6月进行,每年进行一次抽样,为期三年。本研究采用目的取样法和浮游生物网水平取样法,然后将样本带到实验室进行鉴定。对水的物理和化学进行了就地和移地取样,即保存以便进一步运往实验室。研究结果从丰度、分类群和多样性指数等方面反映了浮游植物的变化趋势。这是因为理化因素也有波动,有一个参数高于质量标准,即苯酚含量超过0.02 mg/L。然而,可以得出的结论是,在直落Sirih蒸汽发电厂区域的水域污染水平仍然处于良好类别的低水平,因此它对海洋生物仍然是安全的

: 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.
在持续了大约三年的covid-19大流行期间,巨港市的人们在购买产品时往往更有选择性,其中一种是最受欢迎的巨港食品,即pempek。新冠肺炎大流行也给巨港市的中小企业带来了重大变化。自这次大流行以来,许多中小企业的销售额都出现了下降,其中之一是SMsE Pempek的蛇头鱼。基于这种情况,在2019冠状病毒病大流行期间,需要使用SWOT分析制定战略,以加强生产蛇头鱼的中小企业。这项研究是在巨港市进行的,在一家中小企业的Pempek蛇头鱼中抽取了12名受访者的样本。这家中小企业位于上海。Pakjo Palembang被认为是在COVID-19大流行期间仍然活跃的蛇头鱼pempek的生产商之一。为了在COVID-19大流行期间生存下来,庞贝巨港中小企业必须实施几项有针对性的战略,包括通过Whatsapp应用程序(聊天/电话)改善服务,提供24小时管理服务,以便随时订购,采用按订单下单的方式,创新使用树吉/香兰叶作为庞贝的天然染料,并尽量减少鱼腥味。与黑头鱼养殖户签订谅解备忘录,保证原料供应,价格相对稳定。此外,政府,特别是渔业部门,可以鼓励社区更积极地养殖黑头鱼。

. 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.

: 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.
