Abstract

Water pollution such as in rivers has become a concern due to its impact on health and the decreasing availability of clean water. There is a common assumption that industrial pollution is the main cause of water pollution. However, an interesting fact is that river pollution is largely dominated by contamination from household wastewater (domestic waste) discharged directly into drainage systems and ending up in rivers without prior treatment. Such cases are particularly prevalent in developing countries. Therefore, the challenge is to find solutions to treat domestic wastewater using simpler and cheaper technologies. Current research is focused on treating domestic wastewater especially greywater with eco-enzymes. Eco-enzymes are enzymes produced from the fermentation process of organic materials such as fruit peels or vegetable scraps for a minimum of three months. This paper will review the treatment of greywater using eco-enzymes, including the eco-enzyme production process, its characteristics, greywater characteristics, the methods employed, and the research findings. Finally, the paper will recommend possible avenues for further research related to the treatment of greywater using eco-enzymes

Abstract

The mixture of adsorbents of moringa seed (BK) and natural zeolite of Lampung (ZAL) is placed in a fixed bed adsorber column arranged at a certain height according to the designed height ratio. BK is processed by extraction to remove its oil content while ZAL is activated by chemical and physical treatments. Composition ratio of BK-ZAL (cm/cm) was varied i.e.1:1, 1:2 and 1:3 and concentrations of Pb entering adsorber were 1 ppm and 2 ppm. The adsorption conditions were 20-35 mesh adsorbent size, 4 cm diameter column of adsorber, 5 cm bed height, and 8 liters/3 hours flowrate. Upflow adsorption was performed in a fixed bed adsorption column for 3 hours and Pb solution of output adsorber was taken at every 30 minutes. Analysis of Pb content was performed by Atomic Absorption Spectroscopy (AAS). Adsorbent BK before and after extracted, and after adsorption were characterized using Fourier Transmission Infra Red (FTIR). ZAL before and after activation were characterized using X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), and Fourier Transmission Infra Red (FTIR). The characterization results of XRD, XRF and FTIR showed that the crystalline phases of ZAL increased, the activation process of ZAL only caused a shift in the peak, no significant change in the structure of solids, and the content of impurities in ZAL reduced after activation, thereby enhancing its ability to adsorb Pb. AAS analysis results showed that the best combination adsorbent BK-ZAL (cm/cm) was 1: 2 with the highest effectiveness of the entrapment of Pb metal reached 99.90%. The adsorption capacity of adsorbent was 2.25 mg Pb/ gram adsorbent calculated using Freundlich equilibrium model.

Abstract

Coal Fly Ash and rice husk ash can be utilized by converting it into ZSM-5 synthetic zeolite. One of the influencing factors of ZSM-5 synthetis is ratio of SiO2/Al2O3. Synthesis of ZSM-5 was carried out in an autoclave at a temperature of 180°C with a variation of the ratio of SiO2/Al2O3, namely 20, 30, 40, 50 and 60 mol/mol during 24 hour crystallization using TPABr template. Characterization of ZSM-5 was conducted using X-ray Diffraction, Scanning Electron Microscopy, Adsorption-Desorption Analysis of Nitrogen and Acidity. The results showed that the ZSM-5 was formed in all the variations of SiO2/Al2O3 ratios with the highest percent crystallinity of 52.83%, at the ratio of 50 mol/mol. All products are still in accompany with the formation of side products such as Analsime and Silica Oxide. The ZSM-5 crystal product was in hexagonal shape. Results from Adsorption-Desorption Analysis of Nitrogen indicated that all products were mesoporous materials.

Abstract

This work investigates synthesizing activated carbon obtained from rubber seed shells utilizing several activating agents (KOH, CaCl2, and ZnCl2) for supercapacitor applications. Activated carbon was produced from a rubber seed shell using hydrothermal carbonization at 275 °C for 60 minutes and a 120-minute activation treatment at 800 °C. Various activating agents pronounced impacted the pore architecture, surface area, crystallinity, and level of graphitization, which collectively determined the electrochemical characteristics of the resulting materials. Incorporating activation agents enhances the specific surface area and influences the extent of graphitization of activated carbon. The specific surface area of activated carbon products ranges from 367 to 735.2 m² g⁻¹. Further investigation through electrochemical analysis, conducted with a carefully engineered two-electrode system, demonstrated a peak electrode capacitance value of 246 F g-1 at 50 mA g-1 for an ACZn-based supercapacitor. Supercapacitor cells’ energy and power densities reached significant levels, measuring 5.47 Wh kg-1 and 246 W kg-1, respectively. The RSS-derived activated carbon-based supercapacitor exhibited remarkable longevity in a 5000-cycle test, with consistent capacitance retention and coulombic efficiency of 100.11% and 100%, respectively. This work presents a sustainable pathway for producing activated carbon electrodes, contributing to the global circular economy and demonstrating considerable industrial potential.

Abstract

The processing of mining products in indonesia has not been utilized optimally. One of them is manganese ore. Way kanan is one of indonesia's potential manganese ore sites. The manganese leaching study used a -200 mesh way kanan manganese ore that was reacted with sulfuric acid at concentrations of 0.1 M, 0.5 M, and 1 M, as well as corncob as a reductant. To separate the dissolved iron in the leaching process, the manganese sulfate solution was purified with sodium hydroxide and then filtered to have a manganese sulfate solution free of iron. Manganese was precipitated using oxalic acid. The manganese oxalate precipitation was calcined at a temperature of 350 °c for two hours. The best manganese extraction obtained at 92.3% was at a sulfuric acid concentration of 1 M, a temperature of 80 °c, and a solution volume of 400 ml. Calcination of manganese oxalate converted the material into hausmannite (Mn3O4).

Abstract

Natural dyes are one of the popular choices for textile dyes today. One part of the plant that has the potential to produce natural dyes is cocoa pod husk (Theobroma cacao L.) because it contains several secondary metabolite compounds, such as tannin which produces a brown color. The extraction method used in this research is Ultrasonic Assisted Extraction (UAE). This study aims to obtain the highest yield of natural dye extracts from cocoa pod husk by varying solvent types, extraction time, and material-to-solvent ratios using the UAE method. In addition, the types of compounds contained in extracts of natural dyes and color results on cotton fabrics were also obtained. The extraction process was carried out using several types of solvents, namely methanol, ethanol, acetone, and distilled water with varying extraction times of 30, 60, and 90 minutes. The research results show that the solvent that can extract the best natural dyes was ethanol with a yield of 11.43% and an extraction time of 90 minutes. Variable ratios of material to 96% ethanol solvent were also observed, namely at ratios of 1:5, 1:6, 1:7, and 1:8 for extraction times of 30, 60, 90, and 120 minutes. The research results were obtained for the ratio of material to ethanol solvent; 1:8 (w/v) and extraction time 120 minutes with a dye yield of 12.29%. The results of the UV-visible spectrophotometry analysis were obtained that the maximum wavelength of cocoa pod husk extract was 656.5 nm with an absorbance of 0.532. The results of the Gas Chromatography-Mass Spectrometry (GC-MS) analysis were obtained that the dye compound in the cocoa pod husk was tannin. Tannin compounds are natural dyes that can be applied to fabrics and will reduce the use of synthetic dyes. The application of dye extracts to cotton fabrics produced a brown color.

Abstract

Proses penyulingan minyak serai wangi sangat bergantung dari pasokan bahan bakar karena proses penyulingan membutuhkan pasokan panas untuk mempercepat proses penguapan. Saat ini, proses produksi minyak serai yang dilaksankan oleh UKM/perajin di Indonesia umumnya masih menggunakan cara tradisional yaitu dengan peralatan tungku dan ketel sederhana yang tidak memenuhi standar efisiensi energi dan cenderung menimbulkan banyak polusi. Oleh karenanya, dirasa perlu untuk melaksanakan kegiatan pemberdayaan masyarakat yaitu pemberian pengetahuan dan ketrampilan dalam  penggunaan energi alternatif dengan menggunakan Kompor Pellet Biomassa sebagai pengganti tungku tradisional. Kegiatan pemberdayaan ini diharapkan dapat menjadi solusi yang dapat memecahkan permasalahan yang dihadapi oleh UKM yang mempunyai kesulitan mendapatkan bahan bakar seperti gas elpiji atau kayu bakar. Program pengabdian masyarakat ini merupakan program kemitraan yang dilakukan bersama tiga pihak, yaitu industri biopelet (PT. Indokarya Global Jaya) dan UKM Minyak serai wangi sebagai pengguna bahan bakar pelet. Kegiatan pengabdian masyarakat yang dilaksanakan oleh tim pengabadian kepada masyarakat (PKM) Universitas Lampung bertujuan untuk memperkenalkan dan melatih masyarakat tentang teknologi pembakaran yang lebih ramah lingkungan dan memberikan efesiensi yang lebih tinggi dengan menggunakan pellet biomassa (biopellet) sebagai bahan bakar. Kegiatan pengabdian masyarakat terdiri dari beberapa kegiatan, yaitu: (i) sosialisasi, (ii) pelatihan penggunaan kompor dan proses produksi pelet biomassa (i). Target luaran yang diharapkan pada kegiatan ini adalah masyarakat mendapatkan pengetahuan dan keterampilan dalam menggunakan kompor pelet biomassa untuk sebagai sumber energi dalam proses penyulingan yang lebih ramah lingkungan.Kata Kunci : pelet biomassa, UKM minyak atsiri, energi terbarukan, kompor biomassa
