Abstract

Urban sanitation remained a difficult problem to overcome, particularly waste watermanagement. Improper wastewater discharges that do not meet health and environmentalrequirements maybe harmful to health. In order to control discharges of domestic wastewater,the Governor of East Java issued Regulation No. 72 of 2013 regarding Wastewater Standard forIndustries and/or Other BusinessActivities that includes parameters such as pH, BOD,COD,TSS,Oils and Fats. The purpose of the present study was to determine the system and processesofcommunal WWTP in RT 4 RW 11 on Jalan Kertajaya IV Raya Kelurahan Kertajaya KecamatanGubeng of Surabaya Municipality.This was a descriptive and cross-sectionalstudy. Data were collected through observations,measurements, interviews, laboratory tests, as well as secondary data collection. Water sampleswere taken three times at the inlet and outlet of the WWTP. The collected data weresubsequently analyzed in descriptive manner.Results showed that the inflow was greater than the outflow, leading to overflow of theWWTP. Sources of wastewater conslsted of domestic wastewater, water used to wash utilities,water discharge from motor vehides washing activities. Wastewater was treated by biologicalmethod consisted of an anaerobic system and physical methods involving a filtration system.Wastewater was sampled at the inlet and outlet points of the WWTP using a time-combinationmethod. BOD removal efficiency was found to be 29.9%-67.9%; COD removal efficiency was8.5%-44.6%; TSS removal efficiency was 41.7%-92.3%; Oil and Fat removal efficiency was 5%-61.9%. The quality of treated domestic wastewater of RW 11 Kelurahan Kertajaya did not meetthe deSignated requirements with regard to parameters of BOD,COD,Oil and Fat.It is recomended to improve the processing capacity of the WWTP in order to preventoverflows, increase the dimension of the biological treatment facility, and add a grease trap unitto help the effluent quality to meet the standards stated in EastJava Governor Regulation No. 72of 2013

Abstract

Penelitian ini dilatarbelakangi dengan adanya ketertarikan pada olahraga ekstrim skateboard di kalangan renaja, olahraga skateboard sendiri memiliki resiko yang sangat tinggi, mulai dari cidera ringan seperti terkilir sampai cidera berat seperti patah tulang, tapi masih banyak remaja di Kota Padang tertarik untuk mempelajari olahraga skateboard. Metode yang digunakan pendekatan kualitatif, tipe penelitian studi kasus, pemilihan informan dilakukan dengan cara purposive sampling dengan jumlah 15 informan, pengumpulan data secara observasi, wawancara mendalam dan studi dokumentasi. Data dianalisis dengan teknik analisis interaktif Miles Huberman dengan cara reduksi data, penyajian data dan penarikan kesimpulan. Hasil penelitian menunjukan bahwa adanya daya tarik olahraga estrim skateboard bagi remaja di Kota Padang yaitu (1) dianggap sebagai simbol kebebasan berekspresi, (2) skateboard merupakan olahraga yang tidak kompetitif, (3) olahraga skateboard dijadikan media untuk pelepas stres, (4) untuk menambah relasi (5) skateboard merupakan olahraga yang dianggap “keren” dikalangan remaja.

Abstract

Covid-19 has become a worldwide pandemic and eventually spread to Indonesia. The government is taking preventive measures by COVID-19 vaccination program. People looking for this vaccination information program through online media. However, hoax news about the covid-19 vaccination is spreading more and more because of the lack of ability of the public to distinguish between valid news and hoaxes. This makes hoax news increase its spread quickly. So this study will utilize text mining in classifying hoax news texts for the Covid-19 vaccine using 4 kernels of Support Vector Machine. The data collected from 2 sources, hoax news title data are collected from Kominfo and non-hoax news title data are collected from Kompas. The research methodology used is Knowledge Discovery in Databases. The data will go through several preprocessing stages before testing the model. The results show that the best test results for the model obtained by the linear kernel in the 80:20 data split scenario which after going through an evaluation using a confusion matrix produces an accuracy value of 89,43%, precision 94,93%, recall 87,20%, and f1-score 90,90%.

Abstract

Old coconut meat is usually used for household needs. Usually used for making coconut milk for combination ingredients for cooking every day by the community. Demand increases with certain needs and moments, approaching Eid al-Fitr and Eid al-Adha. Based on the results of a field survey to traditional markets located in the Sungailiat area, grated coconut sellers still use coconut grating machines where in the process of grating they still use human hands, even with the help of wood, in 1 hour they can only grate ± 25 coconuts, so the process is finished. slower. At this stage, we conduct a survey and identify problems, determine data needs, data sources will continue with further data collection from observations and research results will be compared to determine product planning to be modified. This design is an illustration before making machine analysis in the form of construction and other components. In designing the machine, it is necessary to know the grating process that will be carried out so that the results used are maximized. In the trial, it was able to grate ± 190 coconuts per hour so that the coconut grater machine looks more optimal in the grating process.
