Abstract

Sukamoro area, Banyuasin Regency, South Sumatera, was the research location. This investigation focuses on the origin of sandstones from the Talang Akar Formation. In the area of investigation, sandstones are widely dispersed and exhibit a variety of properties. Due to the abundance of sandstones found and their high resistance and physical compactness, an analysis of the original rock can be carried out. Generally, the material that makes up sandstone comes from the previous rock. This investigation was undertaken using a descriptive-analytical methodology to determine the origin of the rock. The collected surface data is subsequently petrographically examined. After determining the composition of the constituent minerals, a provenance analysis was conducted to determine that the Talang Akar Formation's sandstones originated from the Magmatic Arc. Furthermore, the Talang Akar sandstone reveals the origin of the Recycle Orogen. Thus, it is considered that the sandstones of the Talang Akar Formation have seen many uplift episodes as a result of tectonic activity, almost to the point where they have experienced an increase in the maturity or stability of their continental block provenances

Abstract

People’s growth and their activities increase waste generation. Therefore, efforts to reduce waste are needed, including community-based reduction efforts. This research is located in Gading and Dukuh Setro sub-districts in Surabaya City. The purpose of this study was to measure the potential for waste reduction and greenhouse gas reduction. Measurement of waste generation, waste composition, and waste density was based on SNI 19-3964-1994. The researcher conducted sampling in low, middle, and high-income areas, covering 83 families. Greenhouse gas emissions were estimated using the LandGEM (U.S. EPA) method based on the waste disposed at landfill, considering the existing reduction conditions and optimal material recovery. Solid waste generation in 2022 per year was 4.695,58 tons. The largest composition of waste consisted of biodegradable waste (37.13%), plastic waste (25.73%), and diapers and sanitary napkins (18.25%). The average density of loose waste was 152.42 kg/m3. The existing reduction had 1.47% waste bank reduction activity and 0.72% composting reduction activity, for a total reduction of 2.19%. The average optimal reduction was 52.7%, whereas the optimal reduction in the waste bank was 17.5%. The optimal composting reduction was 35.2%. Thus, the existing scenario in 2032 obtained reductions from total landfill gas of 725,498 Gg/year, methane of 193,788 Gg/year, carbon dioxide of 531,710 Gg/year, and NMOC of 8,330 Gg/year. Meanwhile, the optimal scenario for 2032 obtained reductions from total landfill gas of 239.067 Gg/year, methane of 63.857 Gg/year, carbon dioxide of 175.209 Gg/year, and NMOC of 0.412 Gg/year

Abstract

Transportation has an important role in the logistics of a company, both in services and products. Increased orders in 2020 for wooden speaker products at CV. XYZ (Wonoayu-Sidoarjo) makes this company try to minimize transportation costs at their operational level. This study focuses on determining the relationship between changes in the type of fleet vehicle and the depot location on the operational costs of product delivery and the time to return to the depot in terms of adding trips. The methodology used in this study is the CVRP Multi Trip with Heterogeneous fleet vehicle and the Gravity Location Model based on the heuristic method. Saving heuristic method and nearest neighbor are heuristic methods used in computational studies to determine the order of visits to the formed sub-routes. There are 4 scenarios that are modeled to further analyze the results of these computations, namely: (1) CVRP multi-trip of old location with wings box truck, (2) CVRP multi-trip of old location with Fuso truck, (3) CVRP multi-trip of the new location with wings box truck, and (4) CVRP multi-trip of the new location with fuso truck. The results of the study concluded that there is a relationship between: (1) changes in fleet vehicle type with total traveling distance, (2) changes in depot location with total traveling distance, (3) fuel consumption rate on vehicle operating costs, (4) average vehicle speed on the time back to the depot. Scenario 4 is the best scenario in terms of traveling distance, fuel costs and delivery time. However, moving the depot center is not easy, so the scenario 2 is the most applicable condition considering that the fuso truck is available and has a higher utility than the wings box truck

Abstract

Feed is the most important thing in doing a tilapia fish farming. In a feed required appropriate and balanced nutritional content so that fish growth becomes faster. Shrimp waste and tarum leaves are an alternative raw material for the manufacture of tilapia feed because they have a fairly high protein content. The purpose of this study was to examine the comparative effect of adding the percentage of tarum leaf meal and EM-4 fermented shrimp waste on water content, ash content, protein content, fat content, and crude fiber content of feed. The research method used is using the EM-4 fermentation process on shrimp waste. The variations carried out were the concentration of the addition of EM-4 (14,16,18,20, and 22 ml) and the percentage of addition of Wet Shrimp Waste (WSW) and Tarum Leaf Powder (TLP) (90%WSW + 10%TLP, 80%WSW + 20%TLP, 70%WSW + 30%TLP, 60%WSP + 40%TLP, and 50%WSW + 50%TLP). The results showed that the addition of fermented WSW EM-4 and TLP had a significant effect on the protein, fat and crude fiber content, while the water and ash content did not have a significant effect. The best tilapia feed formulation results were obtained at a ratio of 60% WSW and 40% TLP using 18 ml of EM-4 with the results obtained for water, ash, protein, fat and crude fiber content each of 7.09%. ; 12.59%; 29.98%; 7.45%; and 3.49%.

Abstract

The lid-driven cavity is an important fluid mechanical system that serves as a benchmark for testing numerical methods and for studying fundamental aspects of incompressible flow in a confined volume. This paper is concerned with the numerical calculation of the LDC on the 2-D and 3-D model. The commercial software ANSYS Fluent was used for the simulation. In these models of the simulated cases, the lid moves in the x-direction. The 2-D solutions for the driven cavity are calculated for 10 ≤ Re ≤ 35,000 with a 501 × 501 and 601 × 601 grid. The driven 3-D cavity is calculated with a 75 × 75 × 75 grid. The steady flow inside the cavity consists of the velocity distributions at different Reynolds numbers. The present numerical results agree well with the literature analytical solutions.

Abstract

Jolotundo is a village in the Mojokerto Regency area that is located on the slopes of Mount Penanggungan, close to the forest and Majapahit kingdom relics. In Indonesia, public awareness of the importance of health is declining, causing bad behavior and unhealthy environmental conditions in the community. As technology advances, health technology such as orgonite becomes an effective method of treatment or restoration for both physical and psychological health. Unfortunately, no facilities provide a place to support this method. Therefore, it is necessary to have a facility that provides a place of recovery within the orgonite method based on healing and negative energy elimination for physical, mental, environmental, and spiritual well-being. This research employed field studies and literature studies as well as several methods such as observation, documentary, and interview to obtain data, both primary data as a direct data source and secondary data as other supporting data sources. The design applies the theme of therapeutic architecture, the macro concept of tropical architecture, and the micro concept of adaptive land use. The design environment involves green open spaces and maximizes landscape arrangements.

Abstract

Coffee is the bean of the coffee plant and is the source of coffee drinks. Coffee beans must pass through the coffee roasting stage or also called coffee roasting, from this stage of the process the coffee will be roasted and this process also has its own level. At this stage of the roasting process coffee shop business people often do not know this process, then in this case used Local Binary Pattern (LBP) method. LBP is a simple and very efficient texture operator by labeling pixels by doing thresholding on each pixel neighbors and considers the result as a binary number. This method is used to obtain the texture ektrasi of an image. While for the classification method using the Naive Bayes Classifier (NBC) method. Naive Bayes is a simple probabilistic classifier that calculates a set of probabilities by summing the frequencies and combinations of values from a given dataset. The algorithm uses Bayes' theorem and assumes all the independent or non-interdependent attributes given by the values on the class variables. From the test results by comparing training data and testing data obtained an accuracy rate of 81%. For an image-based developed system with display recognition difficulties, this performance is good.
