Abstract

Guidance activities in correctional instututions are one of the efforts to help inmates develop skills and improve their behavior during their rehabilitation period. One form of guidance activity that can be implemented is music arts, especially choir activities. This study aims to determine the implementation of choir guidance activities and their impact on the vocal abilities and attitudes of inmates at Class III Rangkasbitung Correctional Institution. This study used a descriptive qualitative approach with data collection techniques in the form of observation, documentation, and direct involvement during the activity process. The activities were carried out from March to May, 2025 with training sessions held twice a week, every Wednesday and Friday. The materials provided included basic vocal techniques such as breathing, articulation, and intonation, which were then applied to the songs “Indonesia Raya,” “Tanah Airku”, and “Manuk Dadali”. The results showed that choir guidance activities had a positive impact in inmates. Participants showed improvement in singing abilities, especially in articulation, intonation, and vocal harmony. In addition, this activity also increased inmates’ self-confidence, participation, and enthusiasm during the training sessions. Some participants who were initially passive became more confident to perform and actively participate in group activities. Although there were obstacles, such as difficulties in memorizing song lyrics, these challenges could be overcome through repeated practice and facilitator assistance. Therefore, choir guidance activities can be considered an effective arts-based rehabilitation program to support the inmate development process in correctional institutions.

Abstract

Heavy metal elements concentration study has been determined from soils and tailing sediments in laterite nickel post-mining area in Motui District Southeast Sulawesi. This study aimed to determine the concentration of some heavy metal elements, especially Fe, Co, Mn and Cr, from surface soils sediments in waste dump sites and tailing sediments in settling ponds from lateritic nickel post-mining areas. A total of 20 samples consisting of 18 soil samples and 2 tailing sediments samples were systematically collected for the study. The soil samples from the waste dump site profile were collected from 3 layers which were divided based on the colour of the soils from top to bottom, namely Layer C, Layer D and Layer E. Six soil samples were taken from each layer with space between each sample in one layer was about 50 – 60 cm. The samples were sent to the laboratory and analysed using Atomic Absorption Spectrometer (AAS) method to determine the concentration of heavy elements. Metal-bearing minerals detected from the bedrock consists of chromite, manganese, magnetite and limonite which are responsible for the Cr, Mn and Co, and Fe content, respectively. The result showed that Fe content is significantly higher in soil samples from Layer C and tailing sediments with dark red to brown in colour, suggesting the strong relation between Fe content and colour index. The general element mobility trend showed that Mn and Co are positively correlated in soil sampling from all layers and tailing samples, whereas Fe and Cr show a negative correlation trend in Layer C, D and tailing sediments but positively correlated in Layer E.
