AbstractThis research was conducted on November-December 2018 in the Laboratory of Environmental Quality of Culture Fisheries and Marine Riau University. Objective of this study to determine the conditions of TSS and TDS value in the toxicity test treatment aet and survival rate’s Baung fish. Method this research used experiment with completely randomized design (CRD) and 3 replications. LC50 96 hour value determine by using EPA Probit analysis with software of SPSS Program. Result of acute toxicity test that the LC50 96 hour and biological safety level (BSL) value were 230,57 ml/L and 2,30 ml/L. TSS and TDS values were obtained 85,71 ml/L and 2,30 ml/L. then, absolute weight growth, specific growth rate, and survival growth rate values of Baung fish were 2,39 g, 3,42% and 93% respective. Water quality parameters such as temperature range from 26-28 0C, pH ranges from 5,6-8,0, DO ranges from 4,1-2,3 mg/L, CO2 ranges from 8,60-13,50 mg/L and amonia ranges from 0,018-0,056 mg/L.

This research was conducted in October 2022 at the SUPM Natural Feed Labor/Maritime and Fisheries Polytechnic Pariaman. The purpose of this study was to obtain a suitable dose of palm oil wastewater for culturing Skeletonema costatum microalgae, to analyze the chemical composition of Skeletonema costatum microalgae, to identify the ability of Skeletonema costatum to utilize nitrate and phosphate content in palm oil wastewater, to see the effect of Skeletonema costatum on water quality which has been contaminated with palm oil liquid waste. The method used was an experimental method with a one-factor Completely Randomized Design (CRD) consisting of 6 (six) treatment levels and 3 (three) replications. The treatment given was palm oil wastewater with different concentration treatment levels, namely 0%, 10%, 15%, 20%, 25%, 30% with 3 (three) repetitions so that a total of 18 experimental units, culture carried out for 6 days. The results showed that palm oil wastewater had an effect on the abundance of Skeletonema costatum. The best treatment for Skeletonema costatum culture media was P5 (300 ml/L), cell abundance 329,260 cells/mL, biomass (dry weight) 7.27 g, chlorophyll-a 0.84, nitrate 0.759 mg/L, phosphate 0.301 mg/L, protein 30.70%, fat 0.291% and carbohydrates 21.96%. Meanwhile, a good CO2 is P0 (control), the best dissolved oxygen level is P5 (300 ml/L). Water quality parameters for a temperature of 160C, pH 8.2

One of the key ratios in a bank that is essential is the profitability ratio. This ratio, which can be explained by ROA, ROE, and NIM, is related to the bank's profitability. Customers will use a strong profitability value as a point of comparison. Based on data from 2016–2023 taken from the annual report, this study was carried out in Bank Muamalat and employed a trend analysis to see the development of profitability ratios at Bank Muamalat in 2024–2026. Semi-average analytical approach for trend analysis. The analysis revealed that Bank Muamalat's general trends decreased in all three ratios. This may serve as a reminder to the management to adopt policies that are appropriate for the business. However, Bank Muamalat customers can also utilize these results as a guide to make future financial decisions.

This study aims to measure the performance of Indonesian Sharia Banks. Bank Syariah Indonesia is a bank resulting from the merger of three state-owned sharia commercial banks, namely Bank Rakyat Indonesia Syariah, Bank Negara Indonesia Syariah and Bank Syariah Mandiri. Previously, research on these 3 banks had been carried out before the merger occurred. This study seeks to see the performance of Indonesian Islamic Banks after the merger using the Islamicity Performance Index approach. The data used is Bank Syariah Indonesia annual report data for 2021. The results of this study show that two indicators have very satisfactory values, namely Islamic Investment vs. Non-Islamic Investment and Islamic Income vs. Non-Islamic Income, the Equitable Distribution Ratio indicator has a fairly good value, the Profit Sharing Ratio indicator has an unsatisfactory value, and the last two indicators, namely the Zakat Performance Ratio and the Director-Employee Welfare Ratio have very unsatisfactory values.

Semakin maju pesatnya perkembangan teknologi di Indonesia maka semakin banyak perubahan yang berdampak pada kehidupan masyrakat salah satunya dalam perjanjian yang adanya meterai elektronik atau disebut e-meterai. Namun pada penerapannya saat ini meterai elektronik kurang diketahui oleh masyarakat dan hanya orang-orang tertentu saja yang dapat mengetahuinya. Pada hal ini masyarakat umum juga kurang yakin terhadap keabsahan meterai elektronik karena dianggap bisa dipalsukan. Dalam pengumpulan data pada penelitian ini ialah menggunakan jenis penelitian hukum normatif, yaitu dengan cara mengumpulkan sumber data dari bahan literatur. Hasil analisa yang diperoleh pada penelitian ini ialah sebuah dokumen yang diletakkan meterai elektronik juga memiliki keabsahan, karena pemerintah sudah mengeluarkan meterai elektronik yang tentu saja itu sudah sah dimata hukum.
