Abstract

The Asian palm civet (Paradoxurus hermaphroditus) plays a crucial role in the ecosystem as a seed disperser and has economic value in the civet coffee industry. However, monitoring civet activity in captivity is still conducted manually, which is time-consuming and prone to human error. This study aims to develop an automatic monitoring system based on Computer Vision using the YOLOv8 method with the Python programming language. The system can detect civet activities such as eating, drinking, moving, and sleeping through surveillance cameras in real time. The model was trained using a specialized dataset collected from civet enclosures under various lighting conditions and camera angles. Evaluation results show that the model achieved a mean Average Precision (mAP) of 99.5%, precision of 100%, and recall of 99.3%, indicating excellent detection capability. The implementation of this system is expected to assist captive management in monitoring efficiently, reducing reliance on manual supervision, and improving animal welfare through more accurate observation. Furthermore, this system has the potential to be further developed for real-time video-based monitoring and applied to other animal species. Thus, this study not only contributes to the efficiency of Asian palm civet monitoring but also opens opportunities for the application of Computer Vision technology in conservation and wildlife-based industries.

Abstract

Liquid-liquid extraction is one of the methods for separating rare earth elements (REE) in the presence of an extractant. The separation of REE ions, complex with an extractant, involves interfacial migrations that are influenced by the diffusion of the respective ions. Therefore, we performed molecular dynamics simulations on REE ions (La3+, Sm3+, Eu3+, Gd3+, and Tb3+) in a water-n-hexane system to determine if each ion exhibited a distinct diffusion coefficient. By employing molecular dynamics simulations, we calculated diffusion coefficients for these ions based on the Einstein relation. The diffusion coefficients for La3+, Sm3+, Eu3+, Gd3+, and Tb3+ were found to be 4.21×10–6, and 3.96×10–6, 4.57×10–6, 4.17×10–6, and 5.19×10–6 cm2/s, respectively. However, statistical analysis via the Kruskal-Wallis test revealed no significant variance in the diffusion coefficients (p-value greater than 0.05), indicating that diffusion is not a rate-limiting factor in REE separation. The findings suggest that effective mixing during extraction can eliminate the role of diffusion as a differentiating factor in REE separation. Overall, this study offers critical insights into optimizing REE extraction processes

Abstract

Kemiri sunan oil is non-food oil. Therefore, kemiri sunan oil can be a potential raw material for biodiesel synthesis. Kemiri sunan oil has relatively high free fatty acid content so that before the transesterification step with a homogeneous base catalyst it is necessary to esterify it first. In esterification, the water content in oil and fat as raw material for biodiesel affects the conversion rate of free fatty acids into biodiesel, so this needs to be studied. The purpose of this study was to study the effect of water content in kemiri sunan oil on the conversion of free fatty acids into biodiesel at the esterification stage. The research was conducted by quantitative experiment. Variations of water content in kemiri sunan oil were obtained through evaporation at a temperature of 105 oC with time variations of 1, 1.5 and 2 hours. Esterification was carried out at a temperature of 60 oC, mole ratio of oil to methanol of 1:6, reaction time of 1.5 hours, and 98% sulfuric acid catalyst as much as 1%. The results showed that the less water content in the kemiri sunan oil, the less free fatty acids contained in the biodiesel from the esterification result.

Abstract

The development of teacher professionalism in elementary schools depends not only on pedagogical and cognitive competence but also on spiritual intelligence, which forms the foundation of integrity, work ethic, and teacher exemplarity in shaping students’ character. This study aims to describe the management of the peer coaching program at SDN 15 Koto Panjang Kota Solok as an effort to enhance teacher professionalism based on spiritual intelligence. The research employs a descriptive qualitative approach with data collection techniques including observation and data reduction. The findings show that the management of the peer coaching program is carried out through several stages: planning, which involves identifying teachers’ spiritual needs and integrating character values into lesson modules; implementation, which consists of conducting peer coaching sessions twice a month in a safe environment that allows teachers to share challenges, receive technical guidance, and gain spiritual reinforcement from the principal; and supervision, conducted through academic and non-academic monitoring to ensure consistent application of spiritual values and teacher professionalism in teaching practices. This program has been proven to contribute to improving instructional quality, teachers’ emotional resilience, and the strengthening of students’ character. Thus, peer coaching based on spiritual intelligence becomes an effective program for building teacher professionalism while addressing the challenges of moral degradation.   Keywords: peer coaching management, teacher professionalism, and spiritual based

Abstract

Data storage that is not centralized and less dynamic in being accessed by village officials, this is a problem when during the COVID-19 pandemic, work is done online. The research utilizes existing technologies such as the Cloud, so there is no need to provide a local server and access it using a public IP. The cloud used for storage will be installed with Linux Ubuntu 20 in it, then the OwnCloud feature will be configured in it, so that important files in the village office will be uploaded via the owncloud application which can be accessed by the public. The next stage is that each village apparatus will be given access rights according to the position in the village office. It is hoped that this research can support efforts to improve information technology in the village.
