Abstract

Thorium is an essential element as an alternative nuclear fuel to replace uranium. Thorium is found in the mineral monazite, which is a by-product of the alluvial tin mining process. Many methods have been used to extract and separate thorium from uranium and REEs from monazite, one of which is the organic solvent extraction method. In this research, the primene JMT, which is an extractant of primary amine compounds, was used in the method. The studied parameters are feed pH, JMT primene concentration, and stirring speed. The results show that the optimum conditions for Th extraction in monazite using solvent extraction method primene JMT were obtained at pH 0.5, extractant concentration of 2%, and stirring speed of 300 rpm with Th recovery of 94.05% while U and REE were not extracted.

Abstract

Abstract: Batik cual dye wastewater is produced from the batik cual industry in Bangka, which contains Remazol dye, which is carcinogenic and a non-biodegradable organic compound that can be a pollutant for the environment. The elevated levels of remazol dyes in Batik Cual wastewater necessitate effective and environmentally safe waste management methods. One such method is photodegradation, utilizing a Fe3O4/SiO2/TiO2 composite photocatalyst derived from tin tailings sand. The Fe3O4/SiO2/TiO2 composites were synthesized via the hetero-agglomeration method. XRF characterization revealed that the SiO2 content, following purification with HNO3 acid leaching, reached 78.63%. XRD characterization of the tin tailings indicated the presence of peaks corresponding to quartz silica. Phase analysis using XRD diffractograms for the Fe3O4/SiO2/TiO2 composites showed peaks of magnetite, quartz silica, and a predominant anatase TiO2 phase with strong diffraction patterns at 2θ angles of 27.42°; 39.19°; 44.00°, and 54.29°. UV-DRS analysis determined the band-gap energy of the Fe3O4/SiO2/TiO2 photocatalyst to be 1.9 eV. Morphological SEM analysis indicated that the synthesized Fe3O4/SiO2/TiO2 composite had a spherical, uneven, rough, and porous surface. The photodegradation of the Fe3O4/SiO2/TiO2 composite on cual batik dye waste showed that the optimal contact time for photodegradation was 60 minutes, and the catalyst dose was 500 mg at 98.1%. Consequently, these findings confirm that the Fe3O4/SiO2/TiO2 composite is a viable photocatalyst for photodegradation in handling cual batik dye waste.Abstrak:  Limbah zat warna batik cual dihasilkan dari industri batik cual di Bangka yang mengandung zat warna Remazol, bersifat karsinogenik dan merupakan senyawa organik non-biodegradable yang dapat menjadi pencemar bagi lingkungan Tingginya kadar zat warna remazol pada limbah batik cual membutuhkan penanganan limbah yang tepat dan aman bagi lingkungan. Salah satu metode yang dinilai efektif  yaitu metode fotodegradasi menggunakan  fotokatalis komposit Fe3O4/SiO2/TiO2berbahan pasir tailing timah. Karakterisasi XRF menunjukkan kadar SiO2 setelah dilakukan pemurnian acid leaching HNO3 mencapai 78,63%. Hasil karakterisasi XRD tailing timah menunjukkan terdapatnya puncak yang menandakan silika kuarsa. Komposit Fe3O4/SiO2/TiO2berdasarkan analisis fasa menggunakan XRD difraktogram menunjukkan puncak magnetit, silika kuarsa dan didominasi fasa TiO2 anatase pada sudut 2θ 27,42°; 39,19°; 44,00°; dan 54,29. Berdasarkan analisis UV-DRS didapatkan energi ban-gap untuk fotokatalis Fe3O4/SiO2/TiO2sebesar 1,9 eV. Analisis morfologi pada komposit Fe3O4/SiO2/TiO2 menunjukkan bentuk sperik, permukaan yang tidak rata, kasar dan berpori. Uji fotodegradasi komposit Fe3O4/SiO2/TiO2terhadap limbah zat warna batik cual didapatkan waktu kontak optimal fotodegradasi pada waktu 60 menit dan massa komposit 500 mg sebesar 98.1%. Sehingga dengan hasil tersebut dapat disimpulkan bahwa komposit dapat dijadikan fotokatalis dalam proses fotodegradasi dalam menangani limbah zat warna batik cual.

Abstract

A study on the synthesis and characterization of silica gel/chitosan composite derived from tin tailings for removal of Fe(III) in post-tin mining water has been carried out. The silica source used for the synthesis of silica gel is tin tailings. It is produced by the sol-gel method. The characteristics of silica gel from tin tailings sand are white powder with a silica content of 73.58% after compositing with 30 mL and 45 mL chitosan solution, showing that the chitosan phase was successfully formed together with the silica phase. Functional group analysis showed the presence of typical chitosan functional groups (-NH2) at 1629 cm-1 and 1635 cm-1 and typical silica functional groups (-Si-O-Si) at 1000 cm-1 to 1020 cm-1. These functional groups appeared in addition to all variations of the chitosan solution. Morphological analysis shows that in the addition of 45 mL chitosan solution, the silica gel/chitosan composite has a morphology in the form of small round particles with uneven surfaces and more dominant pores. Adsorption study of silica gel/chitosan composite on Fe(III) in post-tin mining water showed 95.5% adsorption efficiency in the addition of 45 mL chitosan solution. The adsorption condition observed is the adsorption time as a fixed variable in this study, which is for 17 hours.

Abstract

The use of local plants in the Bangka Belitung islands, such as shoots of idat (Cratoxylum glaucum), pelawan (Tristaniopsis spp) and shoots of iding-iding (Stenochlaena palustris) has been practiced by local people for a long time as medicinal plants and vegetables. The three plants are natural ingredients that have been studied and contain very high antioxidant and antibacterial compounds. Iding-iding shoots (Stenochlaena palustris) have antimicrobial uses but their use as antiseptics has not been carried out. Iding-iding shoots have been studied to contain many flavonoids, polyphenols, hydroxycinnamic acid and anthrocyanins. In this study, the formulation of hand sanitizer gel preparations from iding-iding leaf extract (Stenochlaena palustris) as a natural antiseptic with varying concentrations in inhibiting the growth of Escherichia coli and Staphylococcus aureus will be carried out in this study. So far, there has been no research using iding-iding leaf extract (Stenochlaena palustris) in hand sanitizer gel preparations. The results showed that the leaf extract of iding-iding shoots had excellent bacterial inhibition at a concentration of 5% on E.Coli and S.Aureus bacteria.

Abstract

Bangka Belitung Province is one of the largest tin producing area in Indonesia. One of the mining sites located on the Sampur Beach, Kebintik Village, Central Bangka Regency. Tin mining activities can increase heavy metals harmful to the environment, such as Cadmium (Cd). This research aimed to measure Cd levels in sediment and seawater, to isolate and identify Cd resistant bacteria from sediment. Cd metal was analyzed using Atomic Absorption Spectrophotometer (AAS). The average Cd metal level in seawater is 0,0080 ppm and in sediment is 0,0086 ppm. Bacteria were isolated using Zobell 2216E media with the spread plate method. The isolated Bacteria were tested for resistance to Cd with concentration of 20 ppm, 50 ppm, 80 ppm, 100 ppm, and 120 ppm. From 16 bacterial isolates that have been obtained, 7 isolates were resistant to all concentrations, 1 isolate was resistant to 50 ppm, 1 isolate was only resistant to 20 ppm, and 7 isolates were not resistant. Based on the results of the analyzed, the seven isolates of resistant bacteria have similarity with Halomonas sp. (R2 and R3), Neisseria sp. (R4), Cupriviadus sp. (R5), Bacillus sp. (R11), Alcaligenes sp. (R12), and Roseobacter sp. (R13).

Abstract

In managing household waste, KSM Srimenanti Jaya has played an active role in supporting the efforts of both the community and the government. Their main services in Kelurahan Srimenanti include waste collection, provision of plant seedlings, and processing of domestic waste. However, until now, no laboratory testing has been conducted on the compost fertilizer they produce, so the quality of the product remains uncertain. Therefore, this community service program is aimed at improving the quality of compost through fertilizer standard certification for KSM Srimenanti Jaya. Based on laboratory test results, most of the compost quality parameters have met the requirements of SNI 19-7030-2004 and are deemed marketable. Nevertheless, some aspects such as pH level, presence of foreign materials, and particle size still need to be optimized. The program also includes outreach on strategies to enhance compost quality, distribution of pocket guidebooks, and the provision of large waste shredding machines. At the conclusion of the activities, an evaluation was conducted which showed that all KSM managers felt greatly assisted and understood the material presented in the program.
