Red mud is a solid waste residue of the digestion of bauxite ores with caustic soda for alumina production. Bintan Island as one of the bauxite mines in Indonesia has a large red mud potential that can be utilized for research utilization. Red mud has a negative impact on the environment because the condition is alkaline, and in the form of fine-grained mud, and the amount is large enough. Over the last decade, research has been conducted to increase the added value of red mud. This journal explains briefly about the potential of red mud in order to be used as reference for red mud development in Bintan Island.

Ekstraksi nikel laterit menggunakan metode hidrometalurgi lebih efisien dari segi konsumsi energi dengan lebih sedikit gas buang dibandingkan dengan metode pirometalurgi. Hal ini menyebabkan nikel laterit berkadar rendah dapat diekstraksi lebih banyak menggunakan metode hidrometalurgi. Salah satu metode hidrometalurgi dalam mengekstraksi nikel dari bijih nikel laterit adalah Atmospheric Acid Leaching. Penelitian ini bertujuan untuk memperoleh data persentase perolehan nikel, menentukan variabel yang paling berpengaruh dan menentukan kondisi optimum dalam proses pelindian. Pada penelitian ini dilakukan variasi pada faktor-faktor yang berpengaruh dalam proses leaching yakni temperatur, konsentrasi asam dan waktu pelindian. Analisis kandungan nikel hasil pelindian dilakukan menggunakan Atomic Adsorbtion Spectroscopy (AAS). Hasil penelitian menunjukkan bahwa persentase perolehan nikel terendah adalah 9,40% Ni dan tertinggi 75,76% Ni. Perhitungan ANOVA digunakan untuk menentukan faktor paling berpengaruh pada proses pelindian nikel laterit. Faktor yang paling berpengaruh dalam penelitian ini adalah temperatur (B), diikuti konsentrasi asam (A), waktu pelindian (C), interaksi konsentrasi-temperatur (AB), interaksi temperatur-waktu (BC), interaksi konsentrasi-waktu (AC) dan interaksi konsentrasi-temperatur-waktu (ABC). Kondisi optimum pelindian diperoleh pada kondisi temperatur 75°C, konsentrasi asam 2,9-3 Molar dalam waktu 69-70 menit dengan perolehan nikel >70%. ABSTRACT - Leaching of Low-Grade Nickel Laterite Ore Using Atmospheric Acid Leaching Method in Hydrochloric Acid. Nickel laterite extraction using the hydrometallurgical method is more efficient in energy consumption with less exhaust gas than the pyrometallurgical method. This method causes the extraction of low-grade nickel laterite ore using hydrometallurgy could be more effective. One of the hydrometallurgical methods to extract nickel from its ore is atmospheric acid leaching. This research aims to determine the percentage of nickel recovery through the leaching process, determine the most influenced leaching factor, and determine the optimum leaching condition. The main factors that influence the leaching process are temperature, acid concentration, and leaching time. Atomic adsorption spectroscopy was chosen to analyze the leaching solution. This research showed that the lowest recovery of nickel leaching was 9,40% of Ni, and the highest was 75,76% of Ni. Analysis of variance (ANOVA) was used to determine the most influenced factor of leaching. The most influenced factor was the temperature (B), followed by acid concentration (A), duration (C), the interaction of acid concentration-temperature (AB), the interaction of temperature-duration (BC), the interaction of acid concentration-duration (AC), and interaction of acid concentration-temperature-duration (ABC). The optimum leaching condition is at 75°C of temperature, 2,9-3 molar of acid concentration, in 69-70 minutes of duration, which has >70% of Ni recovery.

Chitosan; calcium carbonate; DMFC; thermal stability Membrane is the most important part of Direct Methanol Fuel Cell (DMFC) because of its function as a proton transfer. The purpose of this research was studying the effect of calcium carbonate filler to the performance of chitosan (CS)/Calcium Carbonate (CC) composite membrane using 0.02; 0.04; 0.06; 0.08; and 0.10 g of CC. In this study, CS/CC membranes showed high performance for DMFC application. The best concentration of CS/CC was obtained with 0.06 g of CC based on proton conductivity, methanol permeability, and TGA measurements.

The development of infrastructure in archipelago countries often faces difficulties and challenges due to the lack of fresh water. Hence, in some cases, the usage of seawater is favourable, in particular for concrete making. Little studies have been conducted on comparing the seawater, and freshwater concretes, especially on microstructure analysis. The objective of this study was to reveal the compressive strength, elasticity, and microstructure of concrete using seawater and freshwater as the mixing water. The methodology of this study was mix design, making test specimens, curing test specimens, and microstructure analysis. The tests of concretes were conducted for each sample with variations of 1, 3, 7, and 28 days and the mechanical behavior were tested using compressive strength and elasticity as parameters. At the same time, the microstructure was examined using an X-Ray Diffraction (XRD). The results showed an increase in compressive strength and elasticity of seawater and freshwater concretes at all variations with insignificant differences observed between the two types of concretes. It was also discovered that the formation of Friedel's salt (3CaO.Al2O3.CaCl2.10H2O) in the seawater concrete was not in the freshwater concrete. In conclusion, the differentiation of microstructure did not significantly affect the compressive strength and elasticity between seawater and freshwater in mixing concrete.

Methylene blue (MB) is a dye in wastewater from textile industries that pollutes the water environment. Reduction of its content is necessary for protecting humans and the surrounding environment. This study fabricated chitosan/Fe3O4 nanocomposite through the mixture of chitosan from crab shell waste and magnetite (Fe3O4) from local sand iron with sodium tripolyphosphate (STPP)-sulfate crosslinker as an adsorbent to reduce methylene blue content. The obtained composite was characterized by Fourier Transform Infrared (FTIR) Spectrophotometer and X-Ray Diffraction (XRD) instrument. The contents of methylene blue before and after applying adsorbent-based nanocomposite were determined using an ultraviolet-visible (UV-Vis) spectrophotometer. FTIR characterization results show that chitosan and chitosan/Fe3O4 nanocomposite had successfully synthesized based on the typical vibrational peaks. The deacetylation degree of chitosan was 69.79%. Fe3O4, and chitosan/Fe3O4 nanocomposite, were confirmed by XRD patterns. The chitosan/Fe3O4 nanocomposite adsorption capacity reached 45.37 mg/g when adsorption occurred with 20 mg adsorbent, pH 9, and contact time of 1.5 h. Hence, the chitosan/Fe3O4 nanocomposite in this study has potency and is applicable to adsorb MB effectively.

The pokea clamshell contains high calcium content which has the potency to be used as a precursor of calcium in synthesis of hydroxyapatite (HAp). This study aimed to utilize the waste of the pokea clamshells as a precursor of CaO in synthesizing of HAp, and to carry out the characterizations. Analysis of CaO content XRF showed that pokea clamshell after calcination was 94.23% (by weight). The hydrothermal method synthesized HAp confirmed the formation of single phase of HAp as indicated by the sharpness of the phosphate (PO43-) vibration peak at 561.85; 962.01; and 1024.55 cm-1.
