Abstract

Politeknik Kampar merupakan salah satu politeknik yang mempunyai laboratorium miniplan pengolahan CPO menjadi minyak goreng, biodisel dan sabun. Pada saat operasinya pengolahan ini menghasilkan limbah cair dan limbah padat. Limbah cair yang dikeluarkan oleh suatu sistem pengolahan harus dilakukan pengolahan sebelum dibuang kelingkungan. Berdasarkan percobaan yang dilakukan proses yang menghasilkan limbah adalah pada proses degumming dihasilkan air limbah sebesar 159 L per 1 kali proses dilakukan, dimana air limbah ini mengandung gum dan berwarna kuning. Pada proses netralisasi menghasilkan limbah padat yang mengandung soapstock sebesar 10,93 kg limbah per 1 kali proses dilakukan. Limbah padat ini dapat dijadikan bahan baku sabun dengan bilangan penyabunan sebesar 480,7 mgram KOH/1 gram zat uji. Air limbah yang dihasilkan dilakukan uji jartest di laboratorium menggunakan koagulan PAC (poly alumunium clorida) dan flokulan aqua clear. Berdasarkan percobaan uji jartest yang dilakukan didapat kualitas air hasil olahan sudah berada dibawah ambang batas lingkungan baik pH, warna maupun tingkat kekeruhan. Dosis ekonomis koagulan PAC adalah pada penambahan 60 g/L dan dosis aqua clear yang dibutuhkan adalah sebesar 1,2 g/L per 1 kali proses dilakukan. dilakukan pengecekan kadar COD pada air limbah, dari hasil laboratorium didapat kadar COD akhir sebesar 444,9280ppm dan efesiensi penurunan COD sebesar 63,41%. Berdasarkan hasil laboratorium dibuat perancangan unit-unit pengolahan limbah, didesain bak equalisasi, koagulasi, flokulasi dan sedimentasi. Pada penelitian ini perancangan dilakukan untuk bak sedimentasi yakni panjang 1,50m, lebar 3,20m dan tinggi 3,20m dan bak pembubuh dengan pertimbangan sudah memenuhi volume limbah cair yang diolah.

Abstract

Purpose: The aim of this article is to provide education to students on the importance of establishing goals from an early age. Aspirations can be determined if students already know about various professions. The types of work that require education and special skills are known as professions. Therefore, many children do not prepare for what they will become in the future. Methodology/approach: The strategy used to provide knowledge regarding the introduction of various professions is to give direct lectures about various professions, equipped with their advantages and abilities that must be possessed and prepared from an early age. Results/findings: Through discussions with participants, the service team received information that, on average, students only knew about their profession, but did not yet know how to achieve these goals. In addition, many students still do not know the profession of private employees such as company supervisors or BUMN employees. They know only the professions they often see, such as teachers, doctors, police, and traders. This was discovered during the question-and-answer discussions during socialization. Explained the material from the head of service explaining the abilities that must be possessed if students want to become people in this profession Limitation: This service still needs to be improved with further activities to provide more enthusiasm so that children can be enthusiastic about pursuing their dreams Contribution: We would like to express our gratitude for the assistance and cooperation from SD Negeri 50 Palembang for the permission given to the community service team.

Abstract

At the Sari Mukti Landfill, the reduction in the volume of waste entering the final processing is achieved through landfill management, composting, and sorting. The sorting that has been carried out so far is done by scavengers. Based on data and studies conducted at the landfill, it was concluded that the sorting efficiency, on average, between January and February is 0.81%. This efficiency of 0.81% was obtained from sorting in 5% of zones B and C, with a total of 385 scavengers. If we apply the same efficiency to 100% of the area, the number of scavengers required would be 7,700. However, the results of the study do not recommend increasing the number of scavengers. Instead, it is recommended to sort waste at the source. With the sorting mechanisms outlined in the discussion, it is hoped that only a small portion of organic waste will enter the landfill.

Abstract

Activated carbon can be synthesized from lignocellulosic biomass, such as kepok banana (Musa paradisiaca) stems, which are an abundant agricultural waste rich in cellulose (~64%). In this study, kepok banana stems were utilized as a precursor to produce activated carbon using hydrochloric acid (HCl) as the chemical activating agent. The activation process employed HCl concentrations of 1.5, 2.0, 3.0, 5.0, and 7.0 N, with a carbonization temperature of 400 °C for 1 hour and an Fe adsorption contact time of 30 minutes. The resulting activated carbon was evaluated based on its physicochemical properties according to the Indonesian National Standard (SNI 06-3730-1995). The sample treated with 3.0 N HCl showed optimal characteristics, including moisture content of 2.34%, ash content of 0.28%, volatile matter content of 2.05%, and fixed carbon content of 95.33%. Its iodine number reached 1116.98 mg/g, and the Fe ion removal efficiency was 99.14%. FTIR spectroscopy confirmed the presence of functional groups typical of activated carbon—O–H, aromatic C=C, C–H, and C–O—suggesting good adsorption potential. Furthermore, adsorption behavior was analyzed using the Freundlich isotherm model, which describes multilayer adsorption on heterogeneous surfaces. The findings demonstrate that activated carbon derived from kepok banana stems is an effective, low-cost, and environmentally friendly adsorbent for iron removal, suitable for applications in water purification and wastewater treatment.
