Abstract

In line with industrial development and scientific and technological advancement, the use of metals cannot be separated from human life. Aside from benefits, the rapidly increasing industrial developments also give negative impact from their heavy metal waste. Some electroplating waste treatment methods are studied in this research, specifically electrodeposition method, electrocoagulation, and pH 9 hydroxide coagulation method. This research aimed to determine the most effective method and conditions from the 3 methods mentioned above in reducing contents of nickel in the wastewater. The artificial wastewater was made to have the same concentration to waste from electroplating industry; specifically 2154.20 mg/L. The most effective reduction of nickel for this method occurs at 6 volts with final concentration of 404.86 mg/L. The treatment result from electrodeposition was then further processed through two different processes, a electrocoagulation method and pH 9 hydroxide coagulation method. Electrocoagulation process was done for 1 hour with variation in voltage at 5; 7, 5; and 10 volts. Metal Al was used at the anode, while metal Cu was at the cathode. The optimum voltage for this process occurs at 10 volts with final concentration of nickel at 164,98 mg/L, nickel elimination efficiency was at 59.25 %, specific energy at 1.0777 kWh/kg and current efficiency at 32.3 %. Sample from electrodeposition which was processed further with pH 9 coagulation process produced final nickel concentration at 25.59 mg/L, nickel elimination efficiency was at 93.68 %. Keywords: electrocoagulation; electrodeposition; electroplating; hydroxide coagulation; nickel.

Abstract

Indonesia is one of the largest agricultural countries in the world, with the majority of the population working as farmers. Theagricultural industry certainly needs fertilizer to maintain quality, accelerate growth and provide nutrients for plants to grow well. To provide cheap potassium sulphate fertilizer, we conducted a study on "The Effect of Temperature and Time on Yield andPurity K2SO4Fertilizer from gypsum and Ash Bark" as an alternative to commercially available ZK fertilizers. The reason we usedash bark was because it was a waste from cottonwood industry. This study used a single stage methodwhere in this method the final result was not recycled to save time.The variables used are temperature (60oC, 70oC, 80oC) and time (60, 90, 120 minutes). The results showed that the most K2SO4crystals were formed at 80oC for 120 minutes with potassium concentrations of 69.60%.Keywords: potassium sulphate fertilizer, single

Abstract

Treatment of liquid waste using iron coagulant produces a by-product in the form of sludge which requires large handling costs. To reduce environmental pollution and sludge treatment costs, the sludge will be used as raw material for the manufacture of iron coagulant. This study aims to determine whether the sludge from textile WWTP can be used as raw material for iron coagulant. To determine the effectiveness of coagulants made from sludge, this study will compare the results of the coagulation-flocculation process using commercial iron coagulants and iron coagulants made from sludge as well as mixed coagulants with ratios of commercial iron coagulants to iron coagulants made from sludge of 70%, 60%, 50%, 40%, and 30%. The water quality resulting from the coagulation-flocculation process was indicated by pH, color turbidity, Total Dissolved Solid (TDS) and Total Suspended Solid (TSS). The results showed that the water quality of the coagulation-flocculation process was worse when mixed coagulant was used with a smaller ratio of commercial iron coagulant to iron coagulant made from sludge. A mixture of commercial iron coagulant and iron coagulant made from sludge that meets the quality standard for the TSS parameter is a mixed coagulant with a v/v ratio of 70%, while those less than 70% do not meet the quality standard.

Abstract

Petroleum reserves in Indonesia are running low, as well as fossil energy. If these conditions are not handled appropriately and quickly, the Indonesian nation will experience a petroleum crisis. Biomass briquettes are made from a combination of rice husks, taro husks, and a tapioca flour adhesive, and they will be produced as a byproduct of Indonesia's extensive agricultural sector and the growing taro industry. The use of taro skin in conjunction with other raw materials gives this study an element of originality. The purpose of this research is twofold: to disseminate knowledge about the potential of biomass waste, and to analyze how different biomass waste mixtures affect the briquettes SNI-required properties. An experimental approach was used for this study. In this experiment, three different weight ratios of taro husks to rice husks (KT:50%, KT:75%, and KT:100%) were employed as the primary raw materials. Five-and-a-half percent of the briquette dough's overall weight comes from tapioca flour's role as an adhesive. Preparation of briquette materials, carbonization, briquetting, and testing for biomass briquette characteristics are the first steps in the study approach. The calorific value, moisture, ash, volatile matter, binding carbon, and density tests are all part of this battery of analyses. The highest grade briquettes have a calorific value of 3,993.92 cal/g and are made from 100% KT briquettes. KT briquettes with a 75% moisture content are the highest grade briquettes available. At 22.90%, KT briquettes have the lowest ash level of any high-quality briquettes. Briquettes made from 100 percent KT, or 0.09 percent volatile matter, are the highest grade available. KT briquettes, which have a bonded carbon content of 74.59%, are the highest grade option. 50% KT briquettes, with a density of 0.48 g/cm3, are the highest grade briquettes available.

Abstract

In view of information on rambutan creation which is expanding, the misuse of rambutan strips and seeds is likewise expanding. Remembering that rambutan strips and seeds contain a few mixtures that can be utilized as elective unrefined components in the production of bioethanol. This study aims to determine the effect of variations in the addition of yeast on the yield and content of bioethanol, and also to determine the maximum mass of the addition of yeast to acquire the biggest yield and ethanol content. This research went through 5 stages, first stage is the readiness of the skin and seeds of rambutan, second stage is α-cellulose detachment, third step is hydrolysis with 1% HCl to create glucose which will be analyzed using Benedict's reagent and the Luff-Schoorl method. Qualitative analysis showed positive results and glucose levels obtained were 22.39% with a glucose yield of 1.50%. The fourth stage is glucose fermentation by using five days with variations in yeast weight of 5, 6 and 7 grams. The fifth step is to separate the resulting bioethanol by distillation and determine alcohol content using an alcohol refractometer. Yield bioethanol obtained by varying the weight of yeast 5, 6, and 7 grams respectively was 1.05%, 1.18%, and 1.67% with the levels of bioethanol obtained 1.95%, 2.15%, and 3.00%. The highest yield and content of bioethanol were obtained by adding 7 grams of yeast. The yield obtained on this bioethanol is 1.67% and the bioethanol content is 3.00%. Keywords: bioethanol, cellulose, fermentation, hydrolysis, rambutan peels.

Abstract

Abstract: Hygiene is essential in daily life, and soap is vital for effectively cleansing contaminants and bacteria from the skin. Recent innovations in soap-making, including the development of transparent soaps, aim to enhance both functionality and aesthetic appeal. This study explores the incorporation of eco-enzyme, derived from the fermentation of kitchen waste such as fruits, vegetables, sugar, and water, into transparent antibacterial soap. Eco-enzyme contains lipase, trypsin, and amylase, which are effective in inhibiting pathogenic bacteria. The adoption of eco-enzyme not only enhances the sustainability of soap production but also promotes the efficient use of organic waste. This research conducted a laboratory-based experimental investigation to evaluate the effectiveness of eco-enzyme in the production of transparent solid antibacterial soap using palm oil. The process involved several stages: preparation of raw materials, soap production, and subsequent analysis. The results demonstrated that the soap met SNI standards with water content ranging from 12% to 17%, a pH between 9.57 and 9.81, and free fatty acids ranging from 0.9% to 1.7%. The inhibition zone for Staphylococcus aureus was 7.81 mm, indicating a moderate antibacterial effect. These findings suggest that eco-enzyme provides a bacteriostatic effect, inhibiting bacterial growth without necessarily killing the bacteria, and highlight its potential for developing sustainable and effective antibacterial products. Keywords: antibacterial soap, eco-enzyme, Staphylococcus aureus.

Abstract

Cilokolot Village, RT 02 RW 02, Margahayu Selatan, Bandung Regency, is a densely populated area where traditional tempeh production occurs. In this village, there are two small-scale tempeh factories involving seven artisans, processing approximately 700 kg of soybeans daily. This study focuses on one factory, which is smaller and utilizes traditional technology, with a production capacity of 200 kg per day and firewood as its fuel source. The tempeh production process consists of boiling, soaking, separating, washing soybeans, fermenting, and packaging, which generates significant volumes of liquid waste. One of the tempeh artisans also has a livestock farm with ten cattle, fifteen goats, and a few turkeys, ducks, and chickens. Waste from tempeh and animal manure is often discharged directly into rivers and vacant land, leading to air, soil, and water pollution, which poses health risks. Biogas energy is produced through microbial processing of organic waste, such as vegetable scraps, fruit peels, leftover rice, livestock manure, and tempeh waste. The main components of biogas are methane and carbon dioxide. The objectives of this study are: 1) to educate artisans on the negative impacts of tempeh waste and livestock manure on the environment; 2) to install a Wastewater Treatment Plant (WWTP) for managing tempeh waste and cattle manure; 3) to provide training and support for processing tempeh waste and animal manure into biogas and Liquid Organic Fertilizer (LOF); and 4) to conduct training on the application of LOF to crops. The methods employed include outreach, training, technology implementation, ongoing support, and evaluation. The results indicate that: 1) artisans actively participated in socialization sessions addressing the negative impacts of tempeh waste and livestock manure; 2) the WWTP for tempeh waste and cattle manure has been successfully installed on land provided by the artisans; 3) training and support for operating the WWTP resulted in the successful production of biogas and LOF, which provide added value and benefits; and 4) training on the application of LOF to demonstration plots has been conducted, with enthusiastic participation from the artisans.
