Abstract

Sungai Selari Village is an area in Riau Province that features a high density of water activities, including a port where many fishing boats are moored and also serves as a transportation route for fishermen seeking fish. This activity can cause water pollution, which leads to the silting of waters through sedimentation. The activity of sediment input into a body of water can cause changes in the ecosystem, including alterations in sediment texture, organic matter content, and the abundance of macrozoobenthos biota. One organism that can be affected by differences in ecosystems is the macrozoobenthos due to its sedentary nature. This study aims to determine the type of sediment, grain size, and organic matter content, as well as their relationship with macrozoobenthos abundance. This research was conducted in March and April 2023, utilizing purposive sampling techniques at four stations in total. The samples taken were sedimentary substrates and macrozoobenthos. The results indicated that the size of the dominating sediment stalk, specifically the mud fraction, ranged from 14.72% to 71.25%. The types of macrozoobenthos found are grouped into two classes, namely Gastropods and bivalves. Individual abundances range from 0.3 - 4.4 ind/m2, with the highest abundance occurring at station 4 and the lowest occurring at station 1. The organic matter content ranges from 9.27- 34.2%. The relationship between organic matter content and macrozoobenthos abundance exhibits a moderate correlation of 0.506. The relationship between sediment grain size and macrozoobenthos abundance shows a fairly close correlation of 0.544

Abstract

Demam Berdarah Dengue (DBD) merupakan penyakit yang disebabkan oleh virus dengue yang ditularkan oleh nyamuk Aedes spp. dan telah menyebabkan kejadian luar biasa di berbagai wilayah. Pemerintah Kota Kendari telah menggunakan sipermetrin sebagai bahan utama fogging selama enam tahun terakhir. Penggunaan insektisida yang berkepanjangan berpotensi menyebabkan resistensi melalui mutasi gen VGSC (Voltage-Gated Sodium Channel). Penelitian ini bertujuan untuk mengidentifikasi mutasi gen VGSC pada Aedes aegypti sebagai penanda resistensi terhadap insektisida sipermetrin di wilayah kerja Puskesmas Lepo-Lepo, Kota Kendari. Penelitian ini adalah penelitian deskriptif observasional dengan pendekatan laboratorium. Penelitian dilakukan di Laboratorium Biomedik Fakultas Kedokteran Universitas Halu Oleo menggunakan sampel nyamuk Aedes aegypti dari wilayah kerja Puskesmas Lepo-Lepo. Sampel dipilih menggunakan teknik cluster sampling. Teknik PCR dan elektroforesis digunakan untuk mendeteksi mutasi pada domain IIS6 gen VGSC. Tidak ditemukan pita pada hasil elektroforesis, menunjukkan tidak adanya mutasi pada domain IIS6 gen VGSC pada nyamuk Aedes aegypti, sehingga nyamuk masih rentan terhadap insektisida sipermetrin. Hal ini diperkuat oleh hasil Uji Bioassay WHO yang menunjukkan angka kematian nyamuk 100% di setiap kelurahan. Tidak ditemukan mutasi gen VGSC domain IIS6 pada nyamuk Aedes aegypti sebagai penanda resistensi terhadap insektisida sipermetrin menggunakan teknik PCR dan elektroforesis di wilayah kerja Puskesmas Lepo-Lepo, Kota Kendari.

Abstract

Knowledge is very important, in addition to the primacy, it is the command of Allah. Humans have glory because of the science of knowledge. Therefore, the emphasis on the importance of knowledge for people, especially Muslims, has been there since the beginning of Islam revealed to the Prophet Muhammad. Science is meant obtained through the intermediary of the ability to read and write, or in different meanings through careful observation of the situation surrounding human life. This short article will discuss people with knowledge according to a review of the Quran as an effort to find the term-term intellectual according to the thematic study. The results of the study found that the science in the study of Islam has been found to have definition and foundation. There is also an explanation in the Quran about the people of knowledge and the reasons for revelation with regard to the tribunal of science. In fact, a variety of term similar texts with our intelligence as a form of real knowledgeable person is found in the term-term: Ûlû al-‘Ilm, al-Râsikhûn fī al-‘ilm, Ûlû al-Albâb, al-‘Âlimûn and al-‘Ulamâ.

Abstract

Environmental damage is caused by coastal reclamation to advance the economic sector in Batam City. Reclamation can cause changes in the coastline of Batam City. This study aims to determine the extent of changes in the coastline that occurred in Batam City from 2003 to 2023 and to understand the pattern of ocean current circulation in Batam City before reclamation in 2003 and after reclamation in 2023. This study was conducted in January 2024. The method used for data analysis to observe changes in the coastline is the Digital Shoreline Analysis System. Numerical models available in the MIKE21 software to model water circulation in estuary beaches. The study results show that land additions dominated changes in the coastline of Batam City from 2003 to 2023. The sub-district with the most significant addition was Bengkong, with an addition of 816.58 m and an addition rate of 39.79 m/year, followed by Nongsa, with an addition of 279.05 m and an accretion rate of 13.59 m/year. The flow pattern during the ebb and flow before reclamation had a maximum speed of 0.27 m/s, while after reclamation, the maximum current speed increased to 0.33 m/s. It can be concluded that the progression of the coastline primarily drove the changes in Batam City's coastline from 2003 to 2023. Meanwhile, the increasing current speed can reach 0.33 m/s

Abstract

The Rupat Strait, a strategically crucial marine channel separating Sumatra Island from Rupat Island, exhibits complex hydrodynamic characteristics influenced by tidal propagation from the adjacent Malacca Strait. As a vital shipping corridor, the strait's navigational safety is fundamentally governed by its bathymetric profile and tidal regime. This study implements an integrated methodological framework combining in situ bathymetric surveys with MIKE 21 hydrodynamic modeling to assess morphological dynamics quantitatively. Systematic validation of model outputs against field measurements revealed significant spatial variations in seafloor topography, including pronounced shallowing (>6.6 m) and substantial deepening (≤17 m) at distinct locations. Concurrent analysis of tidal data demonstrated extreme water level fluctuations, ranging from -2.36 m during the lowest astronomical tides to +6.28 m during peak tidal surges. These geomorphological alterations appear correlated with anthropogenic pressures, particularly intensive shipping traffic and coastal zone modifications, suggesting a coupled natural-anthropogenic forcing mechanism governing the strait's evolving morphodynamics. The findings highlight the critical need for ongoing monitoring to ensure maritime safety and sustainable coastal management in this rapidly changing marine environment

Abstract

Abstract: The completion of a construction project is determined by various factors. One of these factors is related to the adequate availability of equipment resources both in terms of quantity, type, and function. The process for construction heavy equipment provision is generally carried out through the process of purchasing, renting or leasing. The factors that are considered in the supply of equipment are one of the problems that need to be studied further so that the target of effective project implementation can be achieved. Based on these problems, this study was conducted to identify the factors that are considered by contractors in the process of providing equipment in a construction project. This research is focused on the supply of wheel loader heavy equipment by a contractor company in Banda Aceh City. Data collection was carried out using a questionnaire as a research instrument, and involved the participation of 36 contractors with Medium (M1 and M2) and Large (B1) qualifications. The questionnaire instrument is structured into 6 factors consisting of cost, operation and maintenance factors, heavy equipment investment value, risk, equipment specifications and project conditions, and strategy. The process of data analysis applies descriptive statistical methods. The results of the analysis of the contractor's perception data indicate that the strategic factor is the most considered factor by the contractor in the provision of wheel loader heavy equipment. This condition is known from the indication of the average score of 3.11 as the highest value compared to other factors. The strategic factor becomes a top priority for contracting companies in supporting the improvement of the company's image or bona fide, especially when the company offers its services to the construction owner through a tender process.Keywords: provision, heavy equipment, wheel loader, construction project, Banda Aceh City
