Abstract

Currently, the presence of shellfish waste is increasing but its utilization is still lacking. As much as 66.70% of calcium carbonate is contained in clam shells. This content can reduce iron levels. This research purpose to compare the effectiveness of reducing iron in well water using silica sand and shellfish media. The size of the media is 0.15 mm-0.45 mm. This research used silica sand 60 cm and variations of the clam shell media in the thickness, is 30, 20 and 10 (cm). Apart from that, also uses variations in sampling time on an hourly scale, is 1, 12, 24, 36, 48 (hours). The research results is showed that the average reduction iron, in the sand reactor was 37.09%, in the 30 cm clam shell reactor was 88.64%, in the 20 cm clam shell reactor was 78.45%, and in the 10 cm clam shell reactor was 68 .82%. This research shows that the influence of the thickness of the clam shell media is directly proportional to the decrease in iron levels that occurs.

Abstract

Nile tilapia is a superior commodity that has been developed with high production. Male nile tilapia has a growth rate of 2 times faster than female nile tilapia, so the cultivation of male nile tilapia (monosex) is far more profitable. The masculinization using honey will produce monosexual male nile tilapia, through immersion method using honey. Honey contain flavonoids which function to direct male genitals. Honey also contains potassium which triggers steroid hormones in protein metabolism, brings glucose into cells and stimulates the hypothalamus, so that it can trigger appetite in animals and influence the level of consumption and feed efficiency. This study aims to determine the best type of honey in nile tilapia larvae for consumption and feed efficiency. Honey used in this study were; forest honey (from Bontocani, Selayar, Sumbawa) and livestock honey with a dose of 0.2% of the total volume of solvents, through the immersion method. The seven days old nile tilapia larvae were immersed in the treatments for 24 hours, then they were reared for 60 days. Completely Randomized Design (CRD) with 3 replications per treatment was used in this experiment. The results showed that honey from Bontocani forest produced highest feed consumption and forest honey (from Bontocani, Selayar and Sumbawa) produced highest feed efficiency.

Abstract

Energy utilization in power plants in Indonesia significantly relies on fossil energy sources, especially those obtained from power plants that use coal as the main fuel. The aim of testing co-firing of sugarcane bagasse biomass is to determine the effect of co-firing on the reliability and main parameters of coal-fired power plants and to obtain an overview of the feasibility of implementing co-firing which includes aspects of operational technical evaluation, production cost evaluation and environmental evaluation. The biomass effectiveness test was carried out at PLTU Rembang, with test variables of 100% coal, co-firing test of 1.25% and 2.5% sugarcane bagasse biomass with a maximum operational load of 315 MW for 6 hours. The results of data analysis were carried out descriptively. The tested sugarcane bagasse biomass had a calorific value of 2947 kCal/kg. Meanwhile, the coal used in PLTU Rembang has a calorific value of 4286 kcal/kg. The SO2 emission test results decreased in the Co-firing test of 1.25% sugarcane bagasse and increased in the Co-firing test of 2.5% sugarcane bagasse compared to the 100% coal test, while the NOx emission test results produced during the co-firing test firing 1.25% and 2.5% sugarcane bagasse biomass has a lower value than using 100% coal. The cost of co-firing electricity production from sugarcane bagasse biomass is 1.25% and 2.5% cheaper than the cost of producing 100% coal electricity. To reduce electricity production costs, the sugarcane bagasse biomass co-firing scheme needs to be emphasized by referring to HPT determination in accordance with PLN Perdir No.0004/DIR/2022, so that co-firing electricity production costs can be more economical.

Abstract

Nitrogen is one of the organic compounds contained in liquid waste produced by the tofu industry. In aquatic ecosystems, excessive amount of nitrogen can lead to eutrophication and increase the amount of ammonia, nitrate and nitrite which are poisonous to humans, livestock and wildlife. In order to deal with the issues, photo-catalyst technology is employed to process the organic liquid waste by converting themintoCO_2 and water which are relatively safer. Throughout the process, it requires a medium like resin immobilized photocatalyst-ZnO (RIP-ZnO) to absorb the pollutants. Based on the aforementioned background, this study aims to analyze the impact of RIP-ZnO capacity in reducing the total Nitrogen parameter. The analysis of total Ninthisstudy was conducted by using the Kjeldahl method consisting of three processes, namely destruction, distillation and titration. The research began with the process of making reactor and RIP-ZnO. Subsequently, once the total N concentration is known, the process of resin capacity calculation is continued. As a result, the research findings indicate that the highest resin capacity of 1.14542 reduces the total Nby 33%, while the lowest one of 0.00012 decreases it by 59%. In other words, the resin capacity has an impact on the percentage of total N removal. In conclusion, the lower the resin capacity is, the higher the removal percentage is, and vice versa.
