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

Hypertension is one of the most common noninfectious diseases that affects the elderly. Hypertension is also a leading cause of serious complications such as stroke, heart failure, and kidney disease. Non-pharmacological approaches such as the Mindfulness-Based Stress Reduction (MBSR) method have been proven effective in lowering blood pressure by reducing stress and increasing self-awareness. This study aims to determine the effect of relaxation therapy with the MBSR method on reducing blood pressure among elderly patients with hypertension. This research employed a quantitative approach with a quasi-experimental design. The design used was a pre-test post-test design. The sample consisted of 30 elderly selected using purposive sampling based on inclusion and exclusion criteria. The study was conducted from April 14th to June 3rd, 2025. The intervention given was an MBSR treatment program for two months, eight sessions, including mindfulness meditation, breathing exercises, and relaxation techniques. Blood pressure measurements were taken before and after the intervention. The data were analyzed using the paired t-test. The results showed a significant decrease in systolic blood pressure of P< 0.000 and diastolic blood pressure with P < 0.011 after intervention. The average reduction in systolic blood pressure was 5.13 mmHg, and in diastolic blood pressure was 4.63 mmHg. These findings indicate that the MBSR therapy is effective in helping elderly individuals manage hypertension through stress reduction and enhanced self-awareness

erned office by recording the data on the people who have KPS, PKH or SKTM, to get the Indonesia Smart Card (KIP) program, because many people submit applications and there are many criteria that must be taken into account. faced by the Sipaku Area Village Head Office in determining the priority of potential KIP recipients is very difficult, not transparent and inefficient. Therefore, to overcome this problem, it is necessary to have a system for determining the priority of potential KIP recipients by adding some more basic criteria. In this study a decision support system was designed using the AHP (Analitycal Hierarchy Process) method. The results of calculations using the pairwise comparison matrix for the use of criteria show that the most important priority is shown in the status of an active applicant of 0.391, the second priority is the completeness of the files of 0.406, the third priority is the orphanage of 0.095, the fourth priority is parental income of 0.066, and the priority the fifth is a dependent of 0.041. Meanwhile, for alternative use, the data obtained is that the highest value weight determines the recipient of Smart Indonesia Card Assistance (KIP), namely Rizky Amelia Ritonga with a value of 0.171, the second alternative is Rangga Pranata with a value of 0.141 and the third alternative is Elva Radis with a value of 0.124.

Abstract:This study aims to examine the application of the High-Low method, Scatterplot, and Least Squares in cost analysis, particularly in separating fixed and variable cost behavior. The research uses a library research approach…
ch by collecting and reviewing literature from textbooks, journals, and official publications related to cost estimation and cost behavior modeling. The findings indicate that the High-Low method is simple because it uses only the highest and lowest activity levels, but its accuracy is limited due to reliance on extreme data points. The Scatterplot method provides a visual representation of the relationship between cost and activity, helping identify patterns and potential outliers; however, its results may vary due to subjective judgment in determining the cost line. Meanwhile, the Least Squares method is considered the most accurate because it utilizes all available data to produce the best-fit regression line, although it requires more complex calculations and statistical understanding. Overall, the selection of the most suitable method depends on the objective of the analysis, data availability, and the level of accuracy required
Abstract:Transformasi digital global telah mendorong peningkatan signifikan transaksi lintas batas (cross border digital transaction), yang pada akhirnya menimbulkan kebutuhan mendesak akan regulasi pajak yang adaptif dan efektif.…
. Lahirnya Peraturan Presiden Nomor 68 Tahun 2025 merupakan respon strategis pemerintah Indonesia untuk mengatur pemungutan Pajak Pertambahan Nilai (PPN) atas transaksi digital lintas negara, sekaligus menjaga kepastian hukum serta meningkatkan penerimaan negara. Penelitian ini menganalisis secara komprehensif mengenai implikasi regulasi tersebut terhadap pelaku usaha Indonesia, baik domestik maupun asing, dengan fokus pada aspek implementasi teknis, kesesuaian dengan amanat konstitusi Pasal 23A UUD 1945, potensi sengketa perdagangan internasional, serta dampaknya terhadap kepastian hukum dan tanggung jawab kontraktual. Hasil analisis menunjukkan bahwa meskipun Perpres 68 Tahun 2025 berpotensi memperkuat level playing field dan meningkatkan daya saing usaha domestik, tantangan serius masih muncul terkait keterbatasan akses data transaksi, kepatuhan pelaku usaha asing, serta potensi disharmoni dengan prinsip perdagangan internasional seperti Most Favoured Nation (MFN) dan National Treatment. Dari perspektif konstitusional, regulasi ini memerlukan landasan yang lebih kokoh agar tidak dipandang sebagai ultra vires terhadap Pasal 23A UUD 1945. Penelitian ini menegaskan bahwa keberhasilan implementasi regulasi tersebut bergantung pada integrasi sistem lintas yurisdiksi, penyederhanaan beban administrasi, serta penguatan kerja sama internasional. Dengan demikian, Perpres 68 Tahun 2025 dapat menjadi instrumen penting dalam membangun sistem perpajakan digital yang adil, transparan, dan berdaya saing di tengah kompetisi ekonomi global.
