Abstract

The Bayan traditional house in Lombok, West Nusa Tenggara, exemplifies traditional architecture that integrates Indigenous Knowledge (IK) in building construction. This study aims to analyze the construction techniques of the Bayan traditional house in enhancing earthquake resistance and environmental adaptation while exploring its potential application in sustainable modern architecture. A qualitative research approach with a case study design was employed, incorporating participant observation, in-depth interviews with key informants, and document and visual analysis. Findings reveal that Bayan traditional houses utilize distinctive construction techniques such as nail-free wooden joinery, flexible local materials like bamboo and hardwood, and thatched roofs that adapt to tropical climates. These techniques enhance structural flexibility in absorbing seismic shocks while providing optimal thermal efficiency and natural ventilation. These findings align with previous studies indicating that IK-based structures demonstrate greater resilience compared to modern concrete buildings. This study asserts that IK principles in Bayan traditional houses can be integrated into contemporary architectural design to create more environmentally friendly and disaster-resilient buildings. Therefore, policies promoting the adoption of IK-based construction techniques in modern housing and infrastructure development are essential to enhance sustainability and disaster preparedness in the future.

Abstract

Yellowfin tuna in Gorontalo is very abundant and is often exported outside the region and even abroad as fillets, so yellowfin tuna bones are also very plentiful. The community frequently processes yellowfin tuna bones into kuah asam or namely ilahe. One of the sources of ilahe is Averrhoa bilimbi L., but the leftover tuna bones are only a source of pollution. This research focuses on processing the waste into a product of high nutritional value and highlights the novelty of a more environmentally friendly fish bone calcium extraction method. One of the main novelties of this research is the use of natural materials, namely star fruit, as an alternative for calcium extraction, which reduces dependence on harmful chemicals and supports the principle of sustainability. The extraction method used heat, followed by drying to reduce moisture content, pulverizing (blender) to reduce particle size and sieving. The calcium content in tuna bone meal was then analyzed using the Atomic Absorption Spectroscopy (SSA) method. The results showed that the tuna bone meal was white in colour, and the calcium content was 184.4890 mg/g or 18.45%. This product has the potential to be applied in various fields, such as food, health, animal feed, pellets, and organic fertilizer, as well as a solution to reduce fishery waste and support environmental sustainability.

Abstract

This study aims to determine the kinetics of the saponification reaction in making solid soap from wasted cooking oil and its effect on the quality of the solid soap produced. The novelty of this study lies in evaluates the effect of different NaOH concentrations and reaction durations on the the kinetic model with quality parameters (free fatty acid, free alkali content, and pH) to demonstrating that a pseudo second order reaction mechanism contributes to superior soap characteristics. The method begins with the refining of wasted cooking oil using activated carbon, making solid soap from refined oil with variations in NaOH concentrations of 1; 1.5; and 2 M in 30; 45; and 60 minutes. Determination of reaction kinetics was carried out by titrimetry and testing the quality of solid soap with parameters of free fatty acid content, free alkali, and degree of acidity (pH) based on SNI 3532-2021. The results showed that the saponification reaction followed 2nd order pseudo kinetics. This is supported by the value of the reaction constant reaching 1.0995 min-1 and the coefficient of determination R2= 0,9954. The optimum variation of solid soap obtained is 2 M NaOH concentration in 60 minutes. Soap products produced through pseudo second-order reaction kinetics have high quality with a white appearance, no rancid odor, smooth and soft texture. This is evidenced by the parameters of free fatty acid and free alkali content of 0.1126% and 0.016%. The degree of acidity (pH) of the solid soap produced is also in the range of 9.5-10. All of these parameters have met the criteria for solid soap according to SNI 3532: 2021.

Abstract

The implementation of the Independent Curriculum requires an increase in the need for prospective teachers who are able to design open modules that are in accordance with student needs. The Discovery Learning model can be applied in the open module of the Independent Curriculum because it can improve problem-solving skills, creativity, and student independence and create an interesting and enjoyable learning experience. This study uses an effective qualitative descriptive method to gain in-depth insight into the development of the Independent Curriculum teaching module based on Discovery Learning by prospective chemistry teacher students. The purposive sampling technique ensures that the research subjects are relevant to the focus of the study, namely students taking microteaching courses with a sample size of 21 students. The identity module component obtained very good criteria, the core activity component obtained sufficient criteria, the learning activity component (discovery learning) obtained very good criteria, and the learning assessment component obtained sufficient criteria. The results of the analysis show that although prospective chemistry teacher students have an understanding of the syntactic psychology of Discovery Learning, its application in the Independent Curriculum requires additional expertise. Students need to plan activities that encourage student stimulation and motivation and practice making more holistic assessments, including diagnostic and summative assessments, to ensure that open modules are prepared in accordance with the Independent Curriculum standards.
