Abstract

The negative impact of spreading hate speech on social media has prompted various parties to intervene. Computer science researchers have conducted experiments to find solutions for automated intervention by applying artificial intelligence, such as machine learning and deep learning. The fulfillment of the theory of truth makes the machine learning paradigm considered by scientists to solve problems. However, the increasing size of social media data has shifted its paradigm to deep learning. Deep learning becomes a new normal science after completing the task of classifying hate speech well on a large amount of data. However, any approach will be an anomaly when it cannot complete the task. The accessibility of research resources makes it easier for researchers to determine the nature of their experiments, whether scientific or pseudo-science.

Abstract

Efforts to develop assistive devices for children with disabilities at YPAC Foundation Pangkal Pinang, a school that provides education for children with special needs. This initiative is a form of commitment from the Mechanical Engineering Study Program in covering cooperation in the field of education at the YPAC Pangkal Pinang Foundation, where in 2023 the Mechanical Engineering Study Program at Bangka Belitung University has submitted a walking aid, but there is still much that needs to be developed from the device. The focus of this collaboration is aimed at children with disabilities, who have difficulty in mobility. Based on an evaluation by the UBB team with the General Chairperson of the YPAC Foundation, it was found that the device that we had submitted still had weaknesses in supporting walking training for children with disabilities, so that they still experienced difficulty and discomfort in experiencing walking. As a follow-up, the UBB Mechanical Engineering Team succeeded in updating a flexible walking aid that can be used by children of various ages, is safe when used and is expected to improve the mobility and quality of life of children with disabilities at the YPAC Pangkal Pinang Foundation.

Abstract

Jurusan Teknik Mesin pada tahun 2024 telah melaksanakan melaksanakan pengabdian kepada masyarakat di desa Pergam Kecamatan Airgegas Kabupaten Bangka Selatan. Mitra pengabdian adalah Pemberdayaan Kesejahteraan Keluarga (PKK) Desa Pergam. Untuk lanjutan pengabdian tahun 2025 berdasarkan hasil wawancara dengan bapak Sukardi (kepala desa pergam) dan Ibu Nenih Sumarni (ketua PKK desa Pergam) adalah tentang pembuatan kompos. Saat ini dibutuhkan alat atau mesin untuk membantu dalam produksi kompos. Kendala saat ini yang dialami mitra yaitu pencacahan bahan-bahan untuk kompos masih dilakukan secara tradisional menggunakan pisau atau parang. Selain itu pengadukan untuk mencampur bahan kompos masih dilakukan secara manual sehingga memerlukan tenaga yang besar dan waktu yang cukup lama. untuk mencacah bahan kompos bisanya diperlukan waktu berkisar 30 menit sehingga tidak efektif. Tim pengabdian berencana membantu mitra dengan menyiapkan mesin pencacah bahan organik. Mesin yang akan dihibahkan merupakan mesin dari hasil penelitian mahasiswa program studi Teknik Mesin. Mesin tersebut diharapkan dapat digunakan untuk mencacah bahan-bahan organik untuk bahan pembuatan pupuk kompos. Melalui proposal pengabdian ini, tim pengabdian akan membuat dan menyerahkan mesin pencacah sampah organik ke mitra, melakukan pendampingan penggunaan mesin, dan sosialisasi cara membuat pupuk kompos.

Abstract

Composite materials have become highly important in the manufacturing industry. However, the development of composites often faces the challenge of finding effective, economical, and environmentally friendly reinforcing materials. This study aims to analyze the comparison of physical characteristics in composite materials reinforced with natural fibers through Vickers hardness testing and then compare these hardness values with composite materials reinforced with synthetic fibers. The Vickers hardness testing method adheres to the ASTM E348 microhardness testing standard. The results show that the addition of fibers to composite materials tends to increase the likelihood of voids or trapped air bubbles within the composite material, which increases its porosity value. Furthermore, the use of synthetic fibers, especially carbon fiber, is still superior to pineapple leaf fiber (PALF) because the hardness value of carbon fiber is indeed superior to other fibers. However, pineapple leaf fiber (PALF) has advantages in its stability, is more environmentally friendly, and has a lower production cost compared to synthetic fibers.

Abstract

The cultivation of Alabio ducks (Anas Platyrynchos Borneo) so far is still natural and only involves one parameter; furthermore, each location has different characteristics. The hierarchical structure constructed has a ranking of importance as an alternative option for ducks' development in peatland ecosystems. This research aims to formulate a strategy for duck production in the Hulu Sungai Utara Regency. AHP (Analytical Hierarchy Process) method in this study is used to structure the decision-making flow from goals and alternatives and weigh the variables. Data collection was carried out with duck farming experts from academia, farmer groups, and policymakers. This study found that the availability of feed, both sago (0.254) and bran (0.218), is a significant component from an ecological perspective. Distance to market (0.307) and hatchery location (0.287) is an economic variable. The social part consists of distance from the settlement (0.443) and labor availability (0.247). Meanwhile, the availability of feed (0.282), hatchery technology (0.269), and Mina ducks (0.251) are the development strategies for duck cultivation in swamp areas, and economic stimulus (0.93) is the final contributor.

Abstract

One of the uses of used oil is as fuel for multifuel stoves. A multifuel stove is a stove that has flexibility in its fuel selection. In the operation of a multifuel stove, the air supply plays an important role in the combustion process. This study discusses the influence of air velocity on fire characteristics and water temperature during the heating process. In this study, three variations of air velocity were used, namely 13 m/s, 12 m/s, and 11 m/s. Based on the tests that have been carried out, it was found that the speed of air blown into the combustion chamber can affect the temperature and duration of the flame. The faster the speed of air that is blown into the combustion chamber, the higher the temperature of the flame will be, but the faster the fire will be extinguished. This is because more oxygen is supplied into the combustion chamber, causing the combustion process to take place more quickly and intensely. Meanwhile, regarding the water heating time, the time required by the three variations of air speed to heat 0.5 kg of water to boiling is 1.5–2 minutes, which surpasses the performance of gas stoves and conventional electric stoves.

Abstract

Land cover change on Sumatra Island has accelerated rapidly over recent decades, marked by extensive tropical forest deforestation, widespread peatland degradation, and increasing disaster occurrences. Spatio-temporal analysis using multi-temporal satellite data provides valuable insights into the trajectories of vegetation cover change in this region. This study synthesizes findings on patterns of forest conversion to other land uses (plantations, agriculture, and infrastructure), as well as vegetation recovery patterns following fire events, particularly in peatland areas. The results reveal several dominant change trajectories: (1) deforestation followed by conversion to agricultural and plantation land, (2) cyclical changes in plantation forests, including planting, harvesting, and replanting phases, and (3) natural secondary regeneration on abandoned land after deforestation. Furthermore, in cases where deforestation is driven by land and forest fires, fire frequency plays a significant role in shaping vegetation succession pathways. Areas burned only once are able to recover toward near-original conditions after several years, whereas areas subjected to repeated fires exhibit slower recovery and tend to be dominated by shrub vegetation. These findings highlight the importance of sustainable landscape management informed by spatio-temporal data, including controlling deforestation and restoring peatlands through rewetting and vegetation rehabilitation, to prevent further degradation and support long-term ecosystem recovery.

Abstract

Tropical peatlands are among the most fire-prone ecosystems in Southeast Asia, where recurrent burning causes long-term degradation, carbon loss, and biodiversity decline. Assessing spatio-temporal patterns of recovery is therefore essential for guiding effective peatland restoration and fire prevention strategies. This study investigated vegetation recovery dynamics in a fire-affected peatland in Sumatra, Indonesia. Multi-temporal satellite imagery was processed to extract the Enhanced Vegetation Index (EVI) and Normalized Burn Ratio (NBR). Fire frequency and severity were further analyzed through hotspot distributions and fire history. The results revealed that NBR and dNBR were highly effective in detecting burned areas and assessing severity, while EVI provided complementary perspectives on recovery trajectories. Vegetation in once-burned areas showed relatively steady regrowth, with EVI values approaching pre-fire levels after several years. In contrast, repeatedly burned areas exhibited slower and more heterogeneous recovery, with fluctuating EVI pattern reflecting vegetation growth succession. Field vegetation surveys confirmed that repeated fires drastically simplified forest structure, reducing tree and pole density and favoring shrubs and ferns such as Stenochlaena palustris and Melastoma malabathricum. Overall, the study demonstrates that fire frequency and severity are critical determinants of peatland recovery. The EVI offers valuable insights into vegetation dynamics, while NBR provides reliable fire history mapping. These findings underscore the importance of combining spectral indicators with ground-based vegetation data for long-term monitoring and highlight the need for targeted restoration strategies, including hydrological rewetting and assisted natural regeneration, in repeatedly burned peatlands.

Abstract

Sago is a local food resource with high potential to be developed as an alternative carbohydrate source in Indonesia. One of the critical stages in sago processing is the grating process, which significantly affects production capacity and efficiency. This study aims to analyze the effect of the number of grating teeth on the performance of a sago stem grating machine. Two grating tooth variations, namely 18 × 20 and 20 × 22, were tested using a 7.5 HP gasoline engine. Each variation was tested three times using sago stems weighing 6,000 grams. The observed parameters included grating time, mass of perfectly grated material, imperfect grated material, wasted material, production capacity, and production efficiency. The results showed that the 20 × 22 grating teeth variation produced better performance, with a production capacity of 128.85 kg/h and an efficiency of 94.70%, compared to the 18 × 20 variation with a capacity of 99.65 kg/h and an efficiency of 89.3%. The study concludes that increasing the number of grating teeth significantly improves the performance of the sago stem grating machine.
