Diversity and Conservation Status of Sharks Based on Samudera Kutaraja Fishery Port, Banda Aceh
Get PDFSharks are a group of cartilaginous fish that are vulnerable to the impacts of overfishing due to their slow growth and limited reproductive ability. Therefore, it is important to periodically collect data on shark species to update population information and identify endangered species. This study used a direct observation method with data collection based on morphological characters to identify the shark species found. Data analysis was carried out descriptively qualitatively. The results of the study recorded 44 individual sharks from various species. Chiloscyllium punctatum was recorded as the most commonly found species with 14 individuals, while Chiloscyllium hasselti was only recorded as 5 individuals. Based on conservation status, 5 shark species were found that were included in Appendix II of CITES and there were 3 non-Appendix species. These findings indicate the importance of conservation efforts to prevent future declines in shark population
Composition and Diversity of Trammel net Catches Landed at PPI Cikidang, Pangandaran
Get PDFFishing activities are one of the main economic supports for coastal communities in Pangandaran, especially at the Cikidang Fish Landing Base (PPI Cikidang). Trammel nets are widely used, but the impact on the composition and diversity of the catch is not well understood. This study aims to analyze the dynamics of production, CPUE (Catch per Unit Effort) values, composition, and diversity of trammel net catches from 2019 to 2021. Secondary data from PPI Cikidang were analyzed descriptively and quantitatively, using trend graphs, frequency distribution, CPUE, and the Shannon-Wiener diversity index (H'). The results showed that production and fishing efforts fluctuated seasonally, peaking in mid- to late years. The highest CPUE value occurred in October 2020 at 39.19 kg/trip, while the lowest value was recorded in April 2021 at 14.17 kg/trip. The catch composition was dominated by shrimp, particularly Dogol Shrimp (Metapenaeus monoceros), which increased from 50.61% (2019) to 60.55% (2021). The diversity index showed a decline from 1.50 (2019) to 1.08 (2021), indicating the dominance of certain species and the potential decline in ecosystem stability. These findings highlight the importance of sustainable management of trammel net fishing gear to prevent negative impacts on marine biodiversity in the are

Peningkatan Karakteristik Aspal Menggunakan Bahan Tambah Nano Fly Ash
Get PDFAsphalt is a primary component in road pavement construction. Optimizing the utilization of industrial waste, such as fly ash from coal-fired power plants, is increasingly important as the number of companies using coal as fuel continues to grow. Although fly ash is widely used, applying nano fly ash as an asphalt additive remains limited. This study aims to evaluate the effectiveness of nano fly ash as an additive to improve the characteristics of asphalt. The research follows an experimental method conducted entirely in a laboratory setting. Testing was based on the 2018 Bina Marga Technical Specifications, with procedures aligned to AASHTO, ASTM, and SNI standards to ensure accurate and reliable results. Nano fly ash was added to Pen 60/70 asphalt in variations of 0%, 1%, 2%, and 2.5%. Each asphalt sample underwent parameter tests, including stability, flow, density, and stiffness. Results showed that the 1% addition provided the best outcomes, meeting all specified standards and demonstrating improved asphalt characteristics across multiple parameters. Variations of 2% and 2.5% yielded fewer compliant parameters, suggesting diminishing returns at higher nano fly ash levels. These findings indicate that nano fly ash can be a viable additive for Pen 60/70 asphalt, with a recommended optimal use of 1%. Further studies on economic viability and scalability are suggested to enhance the practical application of this material.

Pengaruh Variasi Temperatur Artificial Aging Terhadap Kekerasan Aluminium 6061 Daur Ulang
Get PDFRecycling is an effective way of utilising scrab ships waste in aluminium 6061. One of the alternative ways of utilisation is by casting. Increasing the hardness of the material after casting is done by artificial aging. The purpose of the study was to determine the material of the castings after the aging process. The research method was sand casting, 450°C heat treatment, quenching with (used) oil cooling media and artificial aging at 190°C with varying resistance times of 1, 5 and 11 hours. The test results after the aging process showed an increase in hardness. The average hardness without heat treatment is 38.6 HRB, then the average hardness of sample AA 1 is 39 HRB. When compared to the average without heat treatment and after aging, it has increased by 1.03%. Then, the average hardness of sample AA 5 is 45 HRB, which is greater than the hardness value of AA 1 hour. Meanwhile, the average hardness of sample AA 11 experienced a decrease in hardness of 40.4 HRB. Structural observations of samples without heat treatment have quite large pores and porosity. The addition of holding time during aging is thought to have no effect on grain size, but changes the grain shape. At the grain boundary of the aluminium matrix, the alloying element Si forms a precipitate that is thought to be a Mg2Si compound. This precipitate is likely to form during the aging process.A maximum 250 word abstract in English in italics with Times New Roman 11 point.
