Abstract

Limbah zat warna dapat memberikan dampak negatif bagi kesehatan dan lingkungan. Metode adsorpsi yang dianggap paling efektif untuk mengelola limbah zat warna memiliki kekurangan karena sistem ini hanya mentransfer limbah ke bahan padat dan adsorben tidak dapat di recycle. Pada studi ini, reaksi degradasi katalitik heterogen zat warna dengan sistem reaksi Fenton dilakukan untuk mengatasi limitasi metode adsorpsi. Katalis heterogen oksida besi/karbon dibuat melalui dua tahapan, yaitu impregnasi garam besi dengan metode incipient wetness dan kalsinasi pada suhu 300 °C. Loading oksida besi divariasikan dari 0.5 sampai 2% massa. Reaksi degradasi katalitik zat warna dengan katalis oksida besi/karbon dilakukan pada sistem batch dengan 200 ml larutan metilen biru (konsentrasi 20 ppm) dan penambahan 5 ml H2O2 50%v/v. Uji adsorpsi tanpa reaksi katalitik dilakukan sebagai pembanding. Hasil penelitian menunjukkan bahwa degradasi katalitik lebih efektif 31.3% dibandingkan proses adsorpsi. Degradasi metilen biru meningkat dengan naiknya katalis loading dan hasil dekolorisasi tertinggi sebesar 0.365 mmol/(gr katalis) dengan katalis 2% oksida besi/karbon. Studi ini menunjukkan bahwa degradasi katalitik dapat menjadi metode yang efektif untuk mengatasi limbah zat warna.Kata kunci: karbon aktif; oksida besi; oksidasi katalitik

Abstract

The industries that produce the most liquid waste in Indonesia are the batik and textile industries. Napthol dyes are the most widely used dyes as dyes or batik dyes which are completely non-biodegradable and can cause cancer, digestive disorders, and weakening of the body's resistance due to disease and environmental pollution. One of the processing methods currently being developed to degrade color in liquid waste is the photocatalyst method. The photocatalyst method can use a photocatalyst semiconductor in the form of TiO2 with a supporting material in the form of SiO2. SiO2 as a supporting material can be obtained from the utilization of the local potential of Karangwuni Kulon Progo beach sand. Dye processing was carried out by varying the irradiation time and concentration of Naphtol Jeans. The degradation process was applied to a 25 ml sample solution with the addition of 5 gr/L catalyst for 24 hours, 48 hours, 72 hours, 96 hours, and 120 hours of irradiation. This study resulted in the highest reduction in naphtol concentration at the concentration variable of 100 ppm with a percentage of 44.4687% and a long irradiation time of 120 hours.

Abstract

This study analyzes the application of the Activity Based Costing (ABC) method in determining boarding room rental rates at Homestay Grace II in Jakarta. The ABC method is considered more appropriate than the method that has been used by Homestay Grace II, which is to follow market rates and consider facilities. The calculation using the ABC method resulted in a room rental rate for type A of Rp. 499,657 per month and type B of Rp. 507,282 per month, lower than the rate used by Homestay Grace II. The difference in rates is due to the difference in overhead costs charged to each room. The ABC method can allocate costs more accurately based on activity consumption in each room type. The study concluded that the application of the ABC method can help boarding room rental business owners in determining more accurate and competitive rental rates. This method is considered more effective and provides more accurate information than the method that has been used by Homestay Grace II.

Abstract

This research examines the role of intelligent forecasting as a key element in modern business success. By leveraging artificial intelligence (AI) technology, big data analytics, and machine learning, intelligent forecasting enables companies to predict market trends and optimize strategic decision-making. The research method was conducted through online webinars involving academics, practitioners, and business actors. The results showed that intelligent forecasting could improve accuracy by up to 98.2% and prediction ratio by 96.5%. However, MSMEs still face challenges in adopting this technology, including limited resources and technological understanding. This research concludes that intelligent forecasting is vital in improving operational efficiency and business competitiveness, but a more inclusive approach is needed to ensure wider adoption across various business scales.

Abstract

Bagi umat Islam adanya sertifikasi halal dapat lebih meyakinkan konsumen terhadap produk yang dikonsumsi. Dalam pelaksanaan pengabdian ini kami mengedukasi dan memperkenalkan kepada masyarakat terkait sertifikasi halal terhadap produk UMK dan UMKM. Dalam Undang-Undang mengenai Cipta Kerja yang menimbulkan implikasi terhadap aturan jaminan produk halal bagi pelaku usaha. Dengan adanya label halal dari Majelis Ulama Indonesia (MUI) pada produk pangan akan menjamin keamanan dan kualitas dari produk itu sendiri dan dunia telah menjadikan konsep halal ini sebagai tolak ukur atas kebersihan, keamanan dan kualitas dari produk. Pemerintah masih melaksanakan program Sehati untuk mempercepat proses sertifikasi halal produk-produk UMK. Namun pendampingan PPH (Proses Produk Halal) belum dapat mencapai target. Oleh karena itu, melalui program pengabdian kepada Masyarakat dengan diadakannya kegiatan sosialisasi dan pendampingan PPH dapat membantu dalam tercapainya target yang diharapkan.
