Abstract

Microhydro Power Plant (PLTMH) is a power plant that utilizes flowing water as energy. The minimum power requirement from PLTMH is 5 kW. The energy value of the microhydro flow is influenced by the water discharge value and the height of the water fall. The higher the water discharge and the height of the water fall, the higher the energy that can be produced. The aim of this research is to calculate the potential microhydro sources in one of the tributary streams in Tarakan City, RT. 05 Kelurahan Pamusian, Kecamatan Tarakan Tengah. The river flow studied has an effective fall height of 0.7 meters. To determine the discharge value, it was obtained using the 90o angle V-Notch Thompson method. Measurements carried out in the morning and evening for 32 days showed an average of power value produced was 8.55 W. Based on this data, This location cannot meet the PLTMH criteria. However, this flow source has potential as a Picohydro Power Plant with a power below 5 kW.

Abstract

Mangrove ecosystems, vital for coastal biodiversity and protection, confront escalating degradation from human and natural influences. Addressing the imperative for precise degradation assessment, this study introduces a Random Forest-based technique, utilizing NDVI (Normalized Difference Vegetation Index) feature extraction within a spatio-temporal framework. The principal aim is to establish a robust approach for evaluating mangrove degradation and land cover shifts. This involves extracting NDVI values from satellite images to monitor vegetation health and changes chronologically. Leveraging the Random Forest algorithm, acknowledged for managing intricate relationships and classifications, further enhances the methodology.By situating the approach spatio-temporally, degradation patterns and alterations in mangrove distribution are traced over time. The temporal progression of the study area is considered, affording a thorough degradation analysis. Outcomes affirm the method's efficacy, evidenced by a Cohen's Kappa Score of 0.96 denoting substantial agreement between predictions and observations. Remarkably high scores across accuracy, precision, recall, and F1-score (all at 0.97) underscore the model's precision in classifying mangrove degradation levels. The amalgamation of the Random Forest-based approach and NDVI feature extraction emerges as a valuable instrument for precise mangrove degradation assessment. The spatio-temporal analysis augments comprehension of degradation dynamics, pivotal for proficient mangrove management and conservation strategies.

Abstract

Globalization fosters economic growth and intensifies competition within the business sector, highlighting the increasing importance of information transparency as a source of competitive advantage. Risk disclosures and Sustainability Reports play a pivotal role in enhancing stakeholder trust and boosting firm value through transparency. This study investigates the impact of risk disclosure and Sustainability Report disclosures on firm value, while also exploring the moderating role of Corporate Governance. Using purposive sampling, data from 80 companies listed in the Kompas 100 index in 2022 were analyzed using E-Views software. The findings reveal that risk disclosure positively influences firm value, whereas the disclosure of Sustainability Reports does not significantly affect firm value. Additionally, CG moderates the relationship between risk disclosure and firm value, reinforcing its negative impact, while CG strengthens the positive relationship between Sustainability Report disclosure and firm value. These results offer valuable insights into the role of transparency and governance in shaping corporate outcomes in a globalized market.

Abstract

Indonesia has great potential to sustainably utilize both marine and terrestrial resources. However, The Harapan Baru Cooperative Group still faces various challenges, such as limited knowledge of fish storage and the use of home gardens as cultivation areas for crops. This community service activity aims to address management and production issues to improve the economy of fishermen in the Harapan Baru Cooperative Group in Tarakan City, North Kalimantan, through the integration of blue economy and green economy concepts. The approaches used in this program include surveys, socialization, training, and evaluation. The identification results obtained during the survey revealed two main issues: the suboptimal income of partners from marine products and the minimal utilization of their yards for agriculture. In the training, partners were educated on various fish storage techniques and preservation methods, as well as the production of organic fertilizer from fish waste and botanical pesticides from Siam weed. The results of the activities showed an increase in understanding and skills among fishermen, especially regarding fish storage and micro farming, which can support local economic and food security. The evaluation results concluded that the average scores obtained by the participants indicated that the majority of partners have a good understanding, with a score of 80.2% for fish storage methods and 95% for the production of liquid organic fertilizer, compost, and botanical pesticides. These results reflect the success of the community service activities.

Abstract

Children with special needs often face challenges in recognizing animal shapes and sounds. This community service program (PKM), based on the Service Learning approach, developed an application called Teh Melati, which utilizes Augmented Reality (AR) by combining 3D animation with traditional 2D flashcards to aid in animal recognition. The PKM was conducted over one day with 32 students with disabilities aged 6–14 years (N=32) at HS-Lantaburo. The Service Learning methodology involved actively engaging the community (teachers, parents, and students) in the design, implementation, and evaluation of the learning intervention. Students participated in an interactive animal exploration game that focused on animal images and sounds. Pre-intervention test scores averaged 63.75, while post-intervention scores increased to 81.25. A total of 25 students (78% of the participants) showed significant improvement. The active participation of teachers and parents in hands-on workshops further extended the impact of the intervention. These results demonstrate that learning gaps in special needs education can be addressed through community involvement and the integration of 3D flashcard animation technology, with Service Learning serving as an effective framework for creating meaningful educational experiences for both the students and the community.
