Abstract:This study aims to Test Wastewater Quality Using the Mpn (Most Probable Number) Method to Detect Total COLIFORM Bacteria. This study uses laboratory analysis, which aims to provide an overview of the microbiological quality…
ity of wastewater based on the presence and number of Coliform bacteria. The working principle of the Most Probable Number (MPN) method in detecting total Coliform bacteria in wastewater is carried out semi-quantitatively by detecting microbial growth through lactose fermentation which produces gas or turbidity in selective liquid media. The implementation procedure includes a presumptive test stage using Lactose Broth (LB) media, a confirmatory test with Brilliant Green Lactose Bile Broth (BGLB) media, and determining the final value by matching the combination of positive tubes with the standard MPN table. From the results of laboratory testing on three domestic wastewater samples (1224 AL, 1225 AL, and 1226 AL), it was found that all samples showed negative results with a combination of 0-0-0 tubes in the presumptive test. This indicates that the tested sample does not contain Total Coliform bacteria or has a value of less than 1000 MPN/100 mL, so that its microbiological quality is declared very good and has met the quality standard threshold set by the government through the Minister of Environment Regulation No. 5 of 2014 and PP RI No. 22 of 2021
Abstract:The purpose of this article is to investigate the methods by which Batak Toba women in Habeahan Naburahan Village, Samosir Regency, resist the concealed practice of marpariban matchmaking. As part of the Batak Toba kinship…
ip structure, Marpariban matching is a traditional practice that places women in a position where they are unable to select their life partners. A form of resistance that is not overtly articulated has emerged as a result of this. Information was gathered using descriptive qualitative methods such as in-depth interviews, documentation, and observation. Relevant data and information are provided by informants who are Batak Toba women in the village of Habeahan Naburahan who have firsthand experience with the Marpariban matchmaking practice and family members who participate in the customary matchmaking procedure. The findings and analysis revealed that the Batak Toba women in this hamlet oppose this matchmaking practice through covert resistance. Some of these behaviors are putting off arranged marriages for school or work reasons, using religious legitimacy as a reason to say no without directly confronting the person, formally accepting arranged marriages with a passive attitude and little emotional involvement, and not talking openly about marriage plans. James C. Scott's theory of resistance says that these activities show that there is concealed resistance, or a sort of resistance that happens while people follow the rules. This suggests that Batak Toba women tend to use subtle opposition as a tactic to preserve their independence inside the patriarchal system rather than openly rejecting the Marpariban norm
Abstract:Metode Profile Matching merupakan salah satu dari Sistem Pendukung Keputusan, yaitu suatu system berbasis komputer guna membantu para pengambil keputusan dalam mengatasi permasalahannya untuk mendapatkan atau menghasilkan…
n keputusan yang tepat. [spk] perhitungan dari metode profile matching cukup sederhana, yaitu dengan membandingkan GAP dengan nilai alternative dan kriteria. Ada beberapa hal yang penting yang perlu diketahui mengenai analisis GAP, yaitu table nilai bobot GAP [1]. Selain itu, analisis GAP juga harus memiliki konsep skala prioritas untuk stiap kriteria Karena kemudahan perhitungan dari metode profile matching serta kebutuhan dan tujuan penelitian yang juga sederhana maka peneliti mengambil judul implementasi perhitungan metode profile matching untuk membantu peneliti memberikan jawaban pada komutias akhwat sholeha khususnya kisaran dalam mendapatkan rumah singgah dakwah yang tepat atau cocok untuk dihuni. Adapun tahapan perhitungan dari Profile Matching adalah Penentuan Bobot Nilai GAP, lalu perhitungan dan pengelompokkan core factor dan secoundary factor, selanjutnya perhitungan nilai total tiap kompetensi kriteria dan terakhir perhitungan rangking [2], [3], [4]. Setelah mendapatkan hasil perhitungan yang tepat terhadap rumah singgah dakwah, perhitungan dihentikan dan hasil seleksi diberikan kepada founder KoAS. Hasil dari seleksi rumah singgah dakwah pada Komunitas akhwat Sholehah (KoAS) Kisaran berupa nama dan nilai.
