Abstract

Abstrak Pati merupakan substrat yang ideal sebagai perekat untuk pembuatan komposit berbahan dasar kayu karena merupakan bahan yang murah, mudah diperoleh dan diproses, serta mengandung ikatan glikosidik reaktif dan gugus hidroksil. Tujuan dari penelitian ini adalah karakterisasi bioadhesive dari pati jagung dan asam sitrat, meliputi viskositas, dan kadar air. Metode yang digunakan dalam penelitian ini meliputi persiapan bahan baku, pembuatan perekat, dan karakterisasi perekat. Hasil penelitian pada perekat menunjukkan bahwa karakterisasi perekat pada pengujian viskositas belum memenuhi standar SNI 06-4565-1998 sebagai perekat untuk papan partikel, sementara kadar air penambahan asam sitrat pada perekat mempengaruhi kadar air, dengan kadar air yang berbeda pada setiap penambahan asam sitrat. Abstract Starch possesses desirable attributes such as cost-effectiveness, availability, ease of processing, and the presence of reactive glycosidic bonds and hydroxyl groups, making it an excellent substrate for wood-based composite adhesives. This research aimed to assess the bioadhesive properties of corn starch and citric acid, specifically focusing on viscosity and moisture content. The methodology encompassed the preparation of raw materials, formulation of the adhesive, and characterization of the adhesive. The findings of the adhesive analysis revealed that the viscosity measurements did not meet the requirements outlined in SNI 06-4565-1998 for adhesives used in wood particle boards. Moreover, the moisture content of the adhesive was influenced by the incorporation of citric acid, leading to varying moisture levels with each citric acid addition.

Abstract

ABSTRACT: This study investigates the development of environmentally friendly briquettes as a sustainable alternative fuel. Production involved utilizing sub-bituminous coal waste and carbon derived from the carbonization of seaweed. The primary objective of this research was to optimize the briquette composition to achieve optimal combustion performance, with a focus on reducing the emissions of harmful combustion byproducts, such as SOx (sulfur oxides), NOx (nitrogen oxides), COx (carbon oxides), and particulate matter. The results indicate that briquettes with a 1:1 ratio of coal to seaweed carbon, carbonized at 300°C (sample 3A1), demonstrate potential as an alternative fuel. The 3A1 briquettes exhibited a calorific value of 4422 cal/g, with SOx and NOx emissions that were 11.11% and 25.00% lower compared to pure coal briquettes. This reduction is attributed to the lower sulfur and nitrogen content in the seaweed, as well as the improved carbon structure stability resulting from the carbonization process at 300°C. The utilization of coal waste and seaweed in the form of briquettes represents a viable approach to mitigating environmental impacts and contributes to the development of clean and sustainable energy.

Abstract

PT Semen Tonasa, especially in the Quality Control unit, still has samples that are tested manually, including the Blaine test, residue test, kiln feed and cement, moisture, and LOI (Loss Of Ignition) so it takes a long time for sample preparation to sample testing. The time to test each sample takes an average of 60 minutes. One type of test that takes a long time is LOI (Loss Of Ingnation) analysis. This test is a test used in inorganic chemical analysis, especially in mineral analysis, by subjecting the sample to a certain temperature. The general objective of this research is to determine the Hotmeal LOI analysis curve for calculating LOI on Hotmeal 05 and 10 and determine the sample preparation steps that will be used in creating a linear regression equation. Meanwhile, the specific aim of this research is to create a formula that is suitable for calculating LOI (Loss of Remembrance) specifically for hot meals 05 and 10. This research was carried out using direct experimental methods and data processing using Microsoft Excel 2013 software. The research was carried out by taking directly raw materials in the form of clinker lumps and Kiln Feed in the factory area, and then preparation and data processing were carried out. The results of this research are that a linear regression equation is obtained, namely y= 1.1824x-6.9094, then this equation is input into a computer device with the method name, namely Hotmeal_2023, to be used as a reference in working on the Hotmeal Sample more quickly, the time used when using this formula is 5 -10 minutes.

Abstract

ABSTRACT: This research aims to characterize the chemical composition of laterite nickel ore and analyze the effect of variations in the mass of cassava rubber starch depressant (Manihot glaziovii) and the pH of the flotation solution on nickel recovery and the content of gangue minerals (Fe2O3 and SiO2) in the flotation process. The laterite nickel ore used was obtained from Southeast Sulawesi. The research was conducted experimentally in the laboratory with pH variations of 5, 7, and 9 and starch depressant masses of 0, 0.1, 0.3, and 0.5 g. The collector used was sodium oleate, and pine oil was used as a frother. The results showed that the laterite nickel ore used as raw material has typical characteristics of laterite ore with a low Ni content and high gangue content. Variations in the mass of cassava rubber starch depressant and pH affected nickel recovery and the selectivity of separation toward gangue minerals. Under acidic conditions (pH 5), increasing the starch mass up to 0.3 g decreased nickel recovery from 58.26% to 36.75%. At neutral pH (pH 7), a recovery of 69.62% was obtained, while at basic pH (pH 9) and a starch mass of 0.5 g, the highest nickel recovery of 76.61% was achieved. However, the use of cassava rubber starch has not yet shown optimal selectivity in reducing Fe2O3 and SiO2 contents. Research using cassava rubber starch has potential as a natural, economical, and environmentally friendly depressant to improve nickel recovery in the flotation process of laterite nickel ore, although further optimization is still needed to improve selectivity toward gangue minerals.
