Abstract

Shipbuilding is one of the marine industries which in development needs to pay attention to various parameters from the sea and land. This research was conducted in March to May 2022 with the aim of identifying the influence of oceanographic factors and water quality on the development of the shipbuilding industry at the fishing port of Sabang City. The oceanographic data used includes tides, wind, bathymetry, and sediment composition observed at 12 station points. The depth and tide data are then processed using QGIS. Wind data was analyzed using the Wind Rose Plot and sediment using the Wentworth scale. Oceanographic factors in Sabang Bay have shown very satisfactory results for the development of fish landing bases. The wind in the waters of Sabang Bay blows northwest with high speeds ranging from 10.00 m/s. The depth of the waters indicates a potential location for ship mooring. Sandy sediment is the most common type of sediment found. The tides that occur in the bay of Sabang are relatively stable. Oceanographic factors in Sabang Bay have shown very satisfactory results for the development of fish landing bases.Keywords:OceanographyShipyardSabang Bay

Abstract

Three-phase Self-Excited Induction Generators (SEIGs) are commonly employed for electricity generation in remote or isolated areas. SEIGs are preferred in such regions due to their ability to create a magnetic field by adding a capacitor to one of their terminals. Nevertheless, a significant challenge in utilizing SEIGs is maintaining a consistent output voltage in the presence of load fluctuations. This study aims to investigate the impact of generator rotation on the SEIG's output voltage and determine the optimal rotation speed required for achieving a stable output voltage. Ensuring stable voltage regulation is crucial to guarantee the proper functioning of all loads connected to the SEIG. Furthermore, operating the SEIG in parallel with other generators is advantageous. The methodology employed in this study involves varying the load supplied by the SEIG at different capacitor values. Unwanted voltage variations occur due to load fluctuations within a generating system or SEIG. Adjustments to the generator's rotation speed are made to uphold a uniform voltage level. The variables considered in this study include the generator's rotation speed, capacitor size, and load fluctuations. Simulation results demonstrate that the SEIG's output voltage is affected by the generator's rotation speed, and maintaining a consistent voltage necessitates appropriate adjustments to capacitor values and generator speed. This research enhances understanding of SEIG characteristics and offers guidance on effective settings for maintaining a stable output voltage at various generator rotation speeds. Future research can focus on practically implementing these findings to enhance the performance of SEIGs in real-world applications

Abstract

This study investigates the impact of solution treatment parameters such as temperature, holding time, and quenching media on the hardness enhancement of wrought aluminum alloy 6061-T6 through precipitation hardening. The objectives of this research are to analyze the influence of solution treatment parameters on hardness enhancement, explore the correlation between the solutioning step and the artificial aging process, and optimize the heat treatment process for improved hardness values. Specimens of 6061-T6 aluminum alloy initially exhibited a hardness of 102 HV. After heating to 500°C with holding times of 45, 60, and 75 minutes, followed by quenching in water and SAE 40 oil, Vickers hardness testing revealed significant changes: hardness dropped to 52 HV after solution treatment, then increased to 63 HV (21.15% increase) for 60 minutes and 64 HV (23.08% increase) for 75 minutes. After artificial aging at 210°C for 120, 180, and 240 minutes, the maximum hardness recorded was 113 HV, marking a 10.78% increase from the initial hardness. The quenching medium also influenced hardness; specimens quenched in SAE 40 oil showed improved hardness compared to those quenched in water, likely due to slower cooling rates that allow for better precipitate formation. The increase in hardness is closely linked to microstructural changes during heat treatment. Solution treatment promotes the dissolution of alloying elements, leading to the formation of fine precipitates during aging. These precipitates impede dislocation movement, enhancing the alloy's strength through precipitation hardening. Thus, the density and distribution of these precipitates significantly contribute to the overall hardness enhancement observed in the 6061-T6 aluminum alloy

Abstract

Perdagangan atau jual beli merupakan akad yang diperbolehkan menurut Al-Qur’an, sunnah, dan ijmak ulama, sehingga hukum asal dari kegiatan jual beli adalah mubah atau boleh, Akan tetapi penting untuk diingat bahwa ada batasan dan aturan tertentu yang perlu diikuti dalam konteks perdagangan Islam. Beberapa prinsip utama yang perlu diperhatikan dalam jual beli menurut perspektif Islam adalah; keadilan, kejujuran, transparansi, dan menghindari riba (bunga) serta unsur-unsur spekulatif yang melanggar prinsip-prinsip syariah. Penelitian ini bertujuan untuk menganalisa praktik jual beli papaya dengan sistem timbangan yang di lakukan oleh masyarakat Hutabargot. Adapaun jenis penelitian ini adalah studi lapangan dengan sifat deskriptif. Pendekatan dilakukan dengan menggunakan hukum normatif. Pengumpulan data melalui observasi, wawancara, dokumentasi dan studi pustaka. Data yang ditemukan kemudian akan di analisis menggunakan dalil nas dan juga pendapat para ulama. Hasil penelitian ini menjelaskan bahwa praktik jual beli papaya yang di lakukan toke di Kecamatan Hutabargot sangat tidak sesuai dengan ajaran Islam, bahkan bias masuk dalam kategori haram. Karena tidak adanya unsur keadilan dan kejujuran dalam hal timbangan. Oleh karena itu, perlu adanya perbaikan dan kesadaran di kalangan pelaku usaha agar praktik jual beli dapat mematuhi prinsip-prinsip syariah dalam Islam.

Abstract

The practice of ‘uang titik’ in artisanal gold mining activities in Hutabargot Sub-district is a form of unwritten contract between landowners and miners in land utilisation. The money point is given as an initial permit accompanied by a profit-sharing scheme of 20% for the landowner, while all risks are borne by the miner. This research aims to analyse the justice and legal certainty aspects of the practice of uang titik based on the perspective of sharia economic law. This research uses a qualitative approach with a normative-empirical method, through in-depth interviews, field observations, and literature studies. The results show that in principle, the practice of uang titik is acceptable in Islamic law through the 'urf approach, but there are inequalities in the distribution of risks and profits, as well as the absence of a written contract which creates legal uncertainty and potential injustice. Therefore, it is necessary to reformulate the contract with a fairer and more transparent approach to be in line with the principles of maqashid sharia, namely justice, protection of the rights of related parties, and environmental sustainability. This study recommends strengthening agreement documents and sharia law education for the community as applicable and sustainable solutions

Abstract

The wealth of natural resources is often not directly proportional to the welfare of the community, triggering social and environmental conflicts and showing signs of the resource curse phenomenon due to weak governance. The prevalence of unlicensed mining activities has caused serious environmental damage, land degradation, and social conflict. This study aims to analyse how the Collaborative Governance framework can be implemented in Aceh to optimise the potential of the Qanun, while overcoming existing structural and institutional challenges. This study uses a descriptive qualitative research method, focusing on Collaborative Governance in Aceh's Mining Management. Data collection techniques include observation, interviews, and documentation, which are essential for gathering rich contextual information on the research topic. The results of research on mining governance in Aceh through the Qanun framework have provided a strong normative foundation, particularly in terms of distributive and procedural justice, the right to sue, and the role of the Wali Nanggroe Aceh. The implementation of collaborative governance is in its emerging phase and is not yet optimal. The main obstacles lie in the initial conditions, which are characterised by power asymmetry and resource disparities, inconsistent institutional design, and collaborative processes that fail to address crucial issues such as unlicensed mining. The failure of conventional governance requires a hybrid governance solution that legalises the informal sector on the condition of environmental and social compliance.
