Abstract

Laundry wastewater contains high levels of Chemical Oxygen Demand (COD) and phosphate (PO₄), contributing to water pollution and eutrophication. This study investigates an integrated treatment approach using poly-aluminum chloride (PAC) coagulation and activated carbon adsorption to improve wastewater treatment efficiency. The research aims to determine the optimal PAC dosage (10% and 15%) and stirring time (0, 5, 15, 30, and 45 minutes) for maximizing COD and PO₄ removal. A batch reactor system was used to conduct the treatment process, and the analysis followed the Indonesian National Standard (SNI) methods. The results demonstrated that the highest removal efficiencies were achieved with a 15% PAC dosage and a stirring time of 45 minutes. Under these conditions, COD levels were reduced from 2189.62 mg/L to 143.47 mg/L, achieving a 93% reduction. Similarly, PO₄ levels decreased from 94.33 mg/L to 5.18 mg/L, corresponding to a 96% removal rate. These findings indicate that the combination of PAC coagulation and activated carbon adsorption is a highly effective treatment method for reducing pollution in laundry wastewater. This hybrid approach meets environmental discharge standards and presents a sustainable solution for large-scale wastewater treatment applications.

Abstract

Hybrid Anaerobic Baffled Reactor (HABR) is a development technology from the Anaerobic Baffled Reactor (ABR), which was already known as a technology that is successful in treating domestic waste. Aims: The objectives of these studies were to investigate the efficiency of reducing BOD and phosphate levels in HABR with zeolite (ZE) and activated carbon (AC) media. Methodology and Results: HABR reactor made of acrylic material with a size of 90 cm x 20 cm x 30 cm. The reactor designed has 7 compartments, with details the first 5 compartments are suspended growth microorganism reactors and the next 2 compartments are attached growth microorganism reactors. Conclusion, significance, and impact of study: The result of the research showed that the efficiency of reducing BOD concentration in the reactor with ZE and AC media were 59.30% and 65.12%, respectively. The final BOD concentration in the AC reactor is 30 mg/L, this value meets the domestic wastewater quality standard required by East Java Governor Regulation Number 72 of 2013 concerning Wastewater Quality Standards for Industry and/or Other Business Activities. The final BOD concentration in the ZE reactor exceeded the required quality standard with a value of 35 mg/L. The final phosphate levels of the two reactors meet the wastewater quality standards for business and/or laundry activities with a maximum phosphate concentration of 10 mg/L. The final phosphate levels in the ZE and AC reactors were 3.74 mg/L and 8.79 mg/L, respectively. The efficiency of phosphate removal in ZE and AC reactors were 70.58% and 30.87%, respectively.

Abstract

PT. Anzon Autoplaza is the official dealer of Toyota vehicle sales in Pontianak. Currently, the inventory and sales system in the sales department is still using a manual system. The company staff is having difficulty controlling and monitoring the inventory of vehicles for sale. Researchers designed an inventory and sales information system using Microsoft Visual Studio 2015 (.NET) with the aim of providing a solution to expedite and enhance the accuracy of vehicle inventory information during sales transactions. In this study, the researcher used a descriptive research method and data collection through interviews, observations, and literature review. The data search method using sequential search techniques. System analysis techniques are object-oriented, while the modeling tool used is the Unified Modeling Language. (UML). As a result, the researchers developed an information system at PT. Anzon Autoplaza that can enhance efficiency and accuracy in processing inventory and sales data. It is hoped that there will be an improvement in the quality of services to the company's consumers, as well as an increase in the effectiveness and efficiency of work

Abstract

Latar belakang : Penyakit Paru Obstruktif Kronis (PPOK) merupakan gangguan paru yang ditandai dengan penyempitan saluran napas dan penumpukan lendir, menyebabkan sesak napas dan penurunan kualitas hidup pasien. Penanganan nonfarmakologis seperti latihan pursed lips breathing (PLB) diyakini mampu memperbaiki pola napas dan meningkatkan oksigenasi. Tujuan : mengetahui pengaruh latihan PLB terhadap pola napas pasien PPOK di RSUD Kartini Karanganyar. Metode : penerapan yang digunakan adalah studi kasus dengan pengukuran kondisi pre dan post intervensi pada 2 pasien memenuhi kriteria tertentu. Hasil : Sebelum intervensi, frekuensi napas pada pasien berkisar antara 25-30 kali per menit, dengan saturasi oksigen (SpO2) sekitar 96-97%. Setelah dilakukan latihan selama 20 menit 2x selama 1 hari, terjadi penurunan frekuensi napas menjadi sekitar 20-26 kali per menit dan peningkatan SpO2 menjadi 98-99%. Pola napas menjadi lebih stabil dan teratur, serta nadi dalam batas normal. Hasil ini menunjukkan bahwa pursed lip breathing efektif dalam memperbaiki pola napas, menurunkan frekuensi napas, dan meningkatkan saturasi oksigen pasien PPOK. Kesimpulan : dengan penerapan teknik Pursed Lips Breathing pada pasien PPOK di RSUD Kartini Karanganyar cenderung mengalami perbaikan pada pola napas pasien
