Abstract

Striped catfish tetraploid induction through heat shock that carried out in this study is not intended to produce on growth fries.But to form a broodstock to produce triploid on growth fries through cross breeding without any physical shock induction process.The fries from the heat shock induction in the previous study were screened or selected by observing the maximum number of nucleoli in fin cells.The number of tetraploid individuals used in the performance test was 105 which were placed in three different concrete tanks.The results showed that the growth of tetraploid striped catfish was more significant than diploid with a difference in the daily weight percentage about 0.497% and 0.158% for length but insignificant differences in FCR and SR.In gonadal development based on histological observations, it was shown that each tetraploid and diploid both male and female striped catfish were at the same level of gonadal maturity.Female gonads were at the previtellogenic oocytes and vitellogenic oocytes, but males are dominated at the stage of spermatocytes and spermatozoa.This histology also shows us that the female gonad was still at the development stage, while the male had entered the mature stage and ready to be spawned.

Abstract

The development of natural adhesives derived from non-fossil resources is very important for the future. This research aimed to develop natural adhesive from maltodextrin and compare it with other natural adhesives such as citric acid and malic acid for particleboard production. The effect of the adhesive raw materials on the physical and mechanical properties of the particleboards was investigated. The sweet sorghum and those natural adhesives were used in the manufacturing of particleboard. The resin content of the natural adhesive was 20 wt% base on air-dried particles. The dimension and density target of the boards were 30 x 30 x 0.9 cm3 and 0.8 g/cm3, respectively. The particleboards were prepared by hot pressing at 200°C for 10 min. The physical and mechanical properties of particleboards were evaluated based on Japanese Industrial Standard for particleboard (JIS A 5908-2003). The results showed that the density, moisture content, modulus of elasticity, and modulus of rupture met the requirements of the JIS A 5908-2003 standard, while the thickness swelling, water absorption, and internal bond did not meet the standard requirements. The results of FTIR analysis indicated the establishment of ester linkages due to the reaction between the natural adhesive and sorghum bagasse that contributed to the excellent physical and mechanical properties of the particleboard. Keywords: cassava, maltodextrin, natural adhesive, particleboard, sweet sorghum

Abstract

Despite being regulated in Law Number 30 Year 1999, the effectiveness of arbitration in Indonesia still faces various challenges, such as lack of public understanding, high costs for small businesses, and limited arbitration infrastructure in the regions. Therefore, there is a need to evaluate and strengthen the role of arbitration to ensure that this mechanism can be a quick, fair solution and support business sustainability in Indonesia. The purpose of this study is to assess the extent to which arbitration has been able to be an effective solution in resolving commercial disputes in Indonesia, identify factors that influence its success, and provide recommendations to increase its efficiency and trustworthiness as a fair and speedy dispute resolution alternative. This research uses a descriptive method with a qualitative approach to describe phenomena systematically and accurately. Data was collected through documentation techniques, analyzing various relevant documents such as reports, archives, or articles. Data analysis was conducted in three stages: data reduction, data presentation, and conclusion drawing validated through triangulation. The results showed that arbitration is an effective commercial dispute resolution mechanism in Indonesia because it offers a fast process, affordable costs, and a final and binding award. Its advantages include flexibility, confidentiality, and international recognition through the New York Convention. However, its optimization requires strengthening regulations and education to overcome challenges such as the lack of understanding of business actors and inconsistencies in the application of the law.

Abstract

Waste of sengon wood could be used as an alternative material in the manufacture of particleboards. However,particleboards made from sengon has seome inferior physical and mechanical properties, which did not meet the Japanesestandard (JIS A 5908: 2003). The aim of this research is to improve the physical and mechanical properties ofsengon particleboard using sorghum bagasse in various raw material composition using citric acid adhesives. Citric acidwas used as a binding agent with 20% adhesive content based on the weight of the air-dried particle. Compositionof fiber mixtures between sengon and bagasse sorghum were set in 100:0, 75:25, 50:50, and 25:75 wt.%. Thetargetted density of particleboard was set at 0.80 g/cm3. The hot-pressing conditions of particleboard manufacturingwere 200°C for 10 min. The physical and mechanical properties of the particleboards were evaluated according toJIS A 5908: 2003 standard. The results showed that the density, moisture content, thickness swelling, modulus ofelasticity, modulus of rupture and internal bond met the requirements of the JIS A 5908-2003 standard. Thus, theadditional of bagasse sorghum becomes an alternative way to enhance the physical and mechanical properties of sengonparticleboard. The addition 75% bagasse sorghum had better moisture content, water absorption, thickness swelling,modulus of elasticity, and modulus of rupture of particleboard.

Abstract

The integration of artificial intelligence into healthcare promises to revolutionize medical diagnostics and service delivery. However, rapid technological advancement has outpaced the development of a specific legal framework, creating significant legal uncertainty. This study aims to examine Indonesia’s legal framework for medical artificial intelligence, identify key regulatory gaps, and propose an adaptive legal model to ensure safe and ethical artificial intelligence adoption. Using a normative juridical approach with statutory, conceptual, and comparative analyses, the study finds that current regulations, including Law Number 17 of 2023 on Health and Law Number 11 of 2008 on Information and Electronic Transactions, provide general but insufficient guidance. Critical issues such as liability for artificial intelligence-induced errors, data governance, algorithmic transparency, and patient consent remain unresolved. This regulatory gap poses risks to patients, healthcare providers, and technology developers. The absence of a robust, adaptive legal framework undermines legal certainty and patient protection, limiting trust and safe adoption of artificial intelligence in healthcare. The study proposes a tiered regulatory model based on international best practices to ensure accountability and foster confidence in artificial intelligence-driven medical services.

Abstract

The growing demand for renewable energy has driven the utilization of biomass as an environmentally friendly alternative energy source. This study aims to develop high-quality biopellets based on Calliandra calothyrsus wood by incorporating Eichhornia crassipes (water hyacinth) and Melaleuca cajuputi (cajuput leaf waste) to enhance combustion efficiency and reduce ash content. Five biomass formulations were evaluated: pure calliandra, pure water hyacinth, pure cajuput leaves, calliandra–water hyacinth (75:25), and calliandra–cajuput leaves (75:25). The produced biopellets were analyzed for their physical characteristics, calorific value, and proximate properties, including moisture content, volatile matter, ash content, and fixed carbon. Results showed that the calliandra–cajuput mixture yielded the best performance, with a density of 0.84 g/cm³, low ash content (2.65%), and a high calorific value (18.2 MJ/kg). The addition of water hyacinth reduced volatile matter but increased ash content. The biopellets from the calliandra–cajuput blend met the SNI 8675:2018 standard for both household and industrial use. This study demonstrates that the integration of locally available biomass waste can significantly improve biopellet quality while supporting sustainable waste management and renewable energy diversification.
