Abstract

Jada Bahrin village has an area of 56 km2, and consists of 3 hamlets. The boundaries of Jada Bahrin Village are, among others, in the north by Kimak Village, in the south by Balun Ijuk, in the west by Kemuja and in the east by Baturusa village. The majority of Jada Bahrin's livelihood is farming (80%). During the 2020-2021 pandemic, the Jada Bahrin village community was classified as having quite low awareness in the implementation of the Covid-19 Vaccination, until March 2022 the achievement rate of vaccine dose 1 was only 60% and dose 2 vaccine was only 40%. Seeing some of the existing problems, the team took several steps to help the community and village officials to overcome these problems. Some of the things that the service team did were collecting data on the number of people who had vaccinated and had not vaccinated, education was carried out through several points of view, namely from the point of view of medicine and science, education about hypertension, health consultation assistance and health screening. The search results from 84 communities showed that up to mid-July 2022, 15.5% of the people had not / did not vaccinate. 69.23% of them are not eligible for the vaccine because of illness.

Abstract

Isotherm models of Cu (II) adsorption in Kolong Bangka’s water onto NaOH-deacetylated shrimp shells waste chitin was studied. The extraction of chitin was carried out through three steps: deproteinization, demineralization and decolorization. The deacetylated shrimp shells waste chitin (DA-SW chitin) were prepared by the reaction of DA-SW chitin with NaOH at varying concentrations of 20, 40 and 60% (%W) with stirring for 1 hour at room suhue where the degree of deacetylation for varying NaOH concentrations were 65.72, 67.44 and 88.98%, respectively based on our previous research. Increasing the NaOH concentration causes the diffusion rate of OH- increase thus realizing the effectiveness of OH- attack on the carbonyl carbon group in chitin acetamide increasing so that the chitin deacetylation process becomes more effective. In order to study adsorbent equilibrium behaviour, Freundlich and Langmuir isotherm models were used based on Cu (II) adsorption data with variations in contact time 5, 10, 15, 20, 25, and 30 minutes. The results showed that the concentration of Cu (II) decreased with the increase of the degree of deacetylation and contact time. The optimum condition for the percentage of Cu (II) adsorption was achieved in DA-SW chitin with NaOH 60% (where the degree of deacetylation was 88.98%) during 30 minutes was 97.19%. The Cu (II) adsorption isotherm model in Kolong Bangka water onto DA-SW chitin is represented by the Freundlich isotherm model where the Cu (II) adsorption mechanism onto DA-SW chitin causes the formation of multilayer surface which may due to Van der Waals force.

Abstract

Inkonsistensi teori C merupakan anomali dimana teori C tidak berlaku dalam proses Agitated Leaching. Hal ini menuntut penjelasan sehingga banyak peneliti berspekulasi untuk menjelaskannya. Contohnya teori A yang kontra- intuitif dan teori B yang cenderung menentang teori A. Dalam penelitian ini telah dilakukan penyelidikan terhadap teori A dan B melalui pendekatan tidak-langsung dengan variabel terikat dari proses Agitated Leaching adalah Total Dissolved Solid (TDS), laju pengadukan sebagai variabel bebas dan variabel tetap adalah rasio solid-likuid (1:20 Gr/mL) dan lama pengadukan (10 menit). Proses pelaruran dilakukan pada keadaan STP dan membatasi proses hanya pada tahap pelarutan sampel menggunakan HNO3 5%. Sampel yang digunakan adalah pasir tailing timah. Hasil penelitian menunjukkan bahwa inkonsistensi terjadi pada laju pengadukan 1000 rpm. Teori A1 tidak dapat disimpulkan keberlakuannya dalam proses pelindian tailing timah. Teori A2 berlaku dalam proses pelindian tailing timah. Teori B berlaku dalam proses pelindian tailing timah.

Abstract

As one of unique non-volcanic geothermal field in Indonesia, mapping the groundwater flow in Nyelanding Village, South Bangka is essential as preliminary study for further exploration activity if the geothermal manifestation. In order to achieve this goal, we conduct a research using natural electrical properties of subsurface, Self-Potentials (SP) method. In this study, fixed-based technique was used where the spacing between measurement stations is the multiplication of 10 m along three lines at the study area. Raw field data (potential value) was corrected to diurnal and closure corrections. Further, SP anomaly was plotted and combined with topography data to be analyzed. The result shows potential value raging from -25mV to 100mV which in agreement with the lowest and highest elevation in topography map, respectively. This means, these values are controlled by topographic feature in the study area. Thus, in conclusion, the groundwater flows from the West to North East and South East part of the study area

Abstract

A study has been carried out on supercapacitor electrodes as an electrical energy storage media based on pepper shell activated carbon. The Synthesis is done by mixing the waste carbon pepper shell with an activator HCl with a ratio of 1 : 4. Furthermore, the activated carbon is activated physically by using a pyrolysis temperature of 600 0C. The SEM results indicate that carbon has a porous morphology with a pore size of 24.6 nm which is a mesoporous category. Electrochemical properties are analyzed using cyclic voltammetry (CV). The CV results at the scan rate of 1 mV/s indicate the specific capacitance value generated is 0.45 Fg-1. The results showed that pepper shell waste has the potential to be used as a supercapacitor electrode material

Abstract

In this research, the purification and characteristics of monazite, a by-product of the tin ore enrichment process. Monazite is given pre-treatment to monazite sand using the mechanical-magnetic separation method to increase the content of rare earth metal elements. Based on the results of the analysis of monazite samples from Tin mine tailings concentrate that has been purified, the dominant elements of the highest rare earth metals are cerium (Ce), lanthanum (La), neodymium (Nd), and Yttrium (Y). The mechanical-magnetic separation method, monazite from Tin mine tailings concentrate can have higher purity. These rare earth metal elements can be further extracted or synthesized; and used as supporting or even main materials in developing advanced technological industries.
