Abstract

Autonomous state theory is a view to see how public policy is implemented. Even if a policy is unable to overcome economic problems because it is not tied to the provision of public goods, the state still has the power to make its own policies. From the perspective of social goals to avoid damage, climate change and disaster adaptation policies in Indonesia are examples of appropriate policies that can be developed using this. This research aims to analyze whether the Autonomous State Theory can be reapplied to the emergence of climate change adaptation policies in the city of Palangka Raya or whether exogenous incentives have more influence on the implementation of climate change policies or not. In this research, the author used qualitative methods. Conducting an in-depth case study on the implementation of climate change policies in the City of Palangka Raya. This may involve interviews with policy makers, stakeholders, and analysis of policy documents. In-depth interviews were conducted with various parties involved in the climate change policy formulation process, namely, government, academics, environmental activists and other stakeholders. In addition, Analyze policy documents, reports and other information resources to understand the context, objectives and impact of climate change policies in the City of Palangka Raya. The data sources for this research are generally primary and secondary data. To be able to answer this research question, analysis techniques using qualitative methods are needed. The results of the research conclude that the exogenous theory is the antithesis of the Autonomous State Theory in formulating public policy regarding climate change in the city of Palangka Raya. This theory emphasizes the importance of involving actors other than the state in reducing the impacts of climate change. Countries must work together with private companies, international organizations, and civil society to develop effective solutions.

Abstract

The use of composites as materials has developed rapidly due to the many advantages they offer compared to alternative engineering materials. In this study, the researchers used Glass Laminated Aluminium Reinforced Epoxy (GLARE) to analyze the results of bending tests on hybrid laminate composites reinforced with fiberglass and aluminum plates. The method used was vacuum bagging, and the sample was reinforced with epoxy resin combined with carbon nanotube (CNT) nanoparticles and aluminum (AL) powder. This study applied variations in resin as adhesive, surface treatments, and the addition of CNT and AL nanopowders to determine their effects on the bending strength of the composite. The results showed that specimens with surface treatment and nanoparticle additions had higher bending strength compared to those without nanoparticles or surface treatment. The highest bending stress was found in the CNT variation specimens, with an average value of 181.4158 MPa. The lowest average bending stress was observed in the plain specimens without nanoparticles and surface treatment, with a value of 151.766 MPa. Macro photo analysis after the bending test showed adhesive failure in the plain variation (no resin adhered to the aluminum surface), and cohesive failure in the CNT variation (resin adhered to the treated aluminum surface). These findings indicate that the addition of nanoparticles improves bending strength. This research plays an important role in understanding the influence of nano adhesives and nanoparticles on the bending strength of hybrid laminate composites.

Abstract

Sistem kelistrikan pesawat memiliki peran penting dalam menjamin keselamatan dan kelancaran operasi penerbangan, salah satunya melalui Transformer Rectifier Unit 3 (TRU-3) yang bertugas mengubah arus AC menjadi DC. Kegagalan pada komponen ini dapat berdampak langsung terhadap sistem standby power pesawat. Penelitian ini dilatarbelakangi oleh pentingnya keandalan TRU-3 dalam sistem kelistrikan pesawat Boeing 737-200, terutama dalam kondisi darurat. Rumusan masalah membahas penyebab kegagalan TRU-3, bagaimana dampaknya, serta bagaimana metode perawatan dan penanganan yang tepat. Penelitian ini menggunakan metode kualitatif deskriptif dengan pendekatan Failure Mode and Effect Analysis (FMEA) sebagai teknik analisis data untuk mengidentifikasi potensi kegagalan, menghitung Risk Priority Number (RPN), dan menentukan prioritas perawatan. Pengumpulan data dilakukan melalui wawancara, studi pustaka, serta pengamatan langsung pada sistem TRU-3. Hasil penelitian menunjukkan bahwa penyebab utama kegagalan TRU-3 meliputi under voltage, over voltage, over current, dan over temperature, dengan nilai RPN tertinggi pada under voltage. Perawatan dilakukan secara preventif (C-check) dan korektif melalui penggantian unit. Penelitian ini menegaskan pentingnya analisis kegagalan berbasis FMEA untuk menjaga keandalan sistem kelistrikan pesawat.

Abstract

This study aims to investigate the effect of sintering temperature variations on the mechanical properties of Al-MWCNT composites produced by the powder metallurgy method. The matrix used was AA1100 aluminum with the addition of 1% nano Multi-Walled Carbon Nanotube (MWCNT). The mixture was compacted in a steel mold and sintered at temperatures of 450°C, 500°C, 550°C, and 600°C, and the results were compared with non-sintered specimens. The findings confirm that sintering at 500°C provides the most optimal results, as shown by a significant increase in hardness of 50.05 HV and improved wear resistance with a wear rate of only 0.4387 mm³/s, which is superior to the non-sintered specimens. EDS analysis revealed that this improvement is related to the lower oxygen content at 500°C, while SEM analysis showed tighter and more uniform particle bonding at this temperature. In contrast, sintering at temperatures above 500°C reduced material quality due to the formation of cracks and surface voids. These results clearly confirm that the increase in hardness and wear resistance of the material can only be achieved at the optimal sintering condition of 500°C.
