Analisis Hasil Produksi Perikanan Budidaya Air Tawar di Kebumen Menggunakan Metode Clustering K-means
Get PDFKebumen, as one of the districts in the south of Central Java Province with an area coverage of 26 sub-districts, has the potential for freshwater aquaculture production to reach 3,316,378 kg in 2022. This production can be optimized by creating clusters in sub-districts in Kebumen to utilize this area. Data mining using the k-means clustering method helps to group sub-district areas so that it can assist in decision making. Tests in data mining using Davies Bouldin with values k=2 to 10 show that the best value results, namely at value k=3, is 0.487. The K-means method with a value of k=3 produces 3 clusters with the result that cluster 1 consists of 19 sub-districts, namely the areas of Petanahan, Bulus Pesantren, Ambal, Mirit, Bonorowo, Prembun, Padureso, Alian, Poncowarno, Kebumen, Pejagoan, Sruweng, Rowokele, Sempor , Gombong, Karanganyar, Karanggayam, Sadang and Karangsambung. Cluster 2 consists of 1 sub-district, namely the Kuwarasan area, while cluster 3 consists of 6 sub-districts, namely the Ayah, Buayan, Puring, Klirong, Kutowinangun and Adimulyo areas

Utilization of Hospital Solid Waste as Paving Blocks
Get PDFA hospital as a health facility has the potential to produce medical waste, which is harmful to the environment, if it is not handled properly and correctly. At Hospital X, infectious medical waste is chopped and sterilized at temperatures above 100oC using a sterilwave to reduce the size of the waste and hand it over to a third party at a substantial cost. This waste has the potential to be used as construction materials, such as paving blocks, which are used as parks in the hospital area. Therefore, this research was conducted to determine the best paving block mix design and composition using chopped medical waste as a fine aggregate substitution. In addition, this research carried out a TCLP test on paving blocks that had the best water absorption to find out whether paving blocks are good enough to strip potential soil contamination. The quality target for paving blocks in this study was to meet class D quality with a minimum compressive strength of 8.5 MPa and a maximum water absorption of 10%. The quality of compressive strength and water absorption was based on SNI 03-0691-1996, and the TCLP test referred to Indonesia Government Regulation Number 22 of 2021. The results showed that the mix design used is 1:5 for the ratio of cement and fine aggregate with an average compressive strength of normal paving blocks of 10 MPa. Whereas paving blocks with a mixture of medical waste with the best absorption were those with as much as 8% substitution of fine aggregate, with an average compressive strength value of 10 MPa. The results of the TCLP test on the best specimens showed that the levels of heavy metals in medical waste paving blocks met the TCLP A quality standards and were safe for use in hospital parks
Cost Benefit Analysis of Energy Retrofitting with the Addition of Ventilation Holes in Middle Low-Income Houshold Buildings
Get PDFThe current climate change is characterized by an increase in the earth's surface temperature; one of the impacts that is felt quite significantly is the thermal comfort conditions in buildings. This will encourage residents to use air conditioning to provide the required level of thermal comfort. From the results of electricity demand forecasts, from 2017 to 2036, electricity demand will increase by 6.4% annually, dominated by the household sector at 38.49%. Efforts can be made to condition the room's thermal comfort to reduce the AC's operating time. This can be realized through building energy retrofitting, especially in middle-low-income households. Retrofitting will also not require high costs, so it suits middle-low-income households. In this research, retrofitting was carried out by implementing ventilation. It is hoped that ventilation will naturally provide air to specific rooms through air movement and exchange. This study implemented 12 variations in ventilation, namely variations with cross ventilation and non-cross ventilation, then varied the size of the ventilation and the number of ventilations. This research was carried out based on simulations using Computational Fluid Dynamics. After carrying out the simulation, it was obtained that the most significant decrease in indoor temperature was when cross ventilation was applied at night with ventilation measuring 30 cm x 70 cm with a total of 4 vents, namely with a decrease in the average indoor temperature of 1.614C. After that, a cost-benefit analysis was carried out to compare the costs and benefits of a project; a cost-benefit ratio of 1.26 was obtained, where the profits were more significant than the expenditure costs, a payback period value of 0.402 was obtained, or the capital could be returned for five months, and savings were obtained. Electricity consumption costs up to year five amount to IDR 24,340,306
Analysis of The Relationship of Rework and Inventory to Waste in The Ciputra Hospital Surabaya Project
No full textCurrently, the construction sector is adopting the theory of production in the manufacturing industry, known as lean construction, to reduce waste and increase value. Last Planner System (LPS) has not been widely used and has good potential because the advantage of LPS is to identify a job along with obstacles to improve performance in a construction project. In the construction of Junior High School (SMP) Al-Falah, it has work obstacles due to erratic weather so that the project is delayed, the author conducts a field survey to analyze the actual progress in the field, LPS has work indicators / work flow to measure the extent to which work indicators can be realized properly, the LPS work flow are Master Plan, Phase Pull Planning, Lookahead Planning, Constraints Analysis, Shielding Production, and Percent Plan Complete (PPC) as a standard for measuring whether project productivity is realized properly or not. In this study, the results of the implementation using LPS on the Al-Falah Junior High School construction project show that the lowest PPC can be seen in week 7, which is 0% because there is no work achievement so that the work is delayed, while in week 16 it can be seen that PPC has increased dramatically to 96%. Then after averaging the PPC of 51% which means that LPS has not been able to increase the reliability of planning above 70%, (Ballard, 2000)
Thermal Analysis of Greenhouse Environment Using Computational Fluid Dynamics (CFD), Case Study in ITERA
Get PDFGreenhouse is a modern agricultural technology that allows for increased agricultural yields. The purpose of this study was to analyze the thermal distribution in the greenhouse of the Sumatra Institute of Technology (ITERA) in 3 time conditions, namely in the morning, afternoon and evening. The method used is CFD modeling using Solidwork. The dimensions of the greenhouse are 12.5 x 25 x 4.26 m³. The greenhouse is divided into a grid into 20 thermal measurement points separated by 2.5 m. The greenhouse has 2 cooling pads and 2 exhaust fans separated by 12.5 m. Model validation using MAPE and R2. The results of the analysis show that 3 models have valid results with MAPE 10% and R2 0.75 and can continue in the review of thermal distribution. of the 3 time condition models that provide a thermal distribution of 28 - 37 ℃. Morning conditions are hotter than afternoon and evening. Cold air from the cooling pad sucked by the exhaust fan is only able to control an area 50%. So the thermal distribution of the greenhouse needs improvement
