Abstract

Air pollution is one of the most dangerous and worrying. One of the causes of air pollution is dust or Total Suspended Particulate (TSP), namely particles with a diameter of <100 μm. The Total Suspended Particulate causes visual distrurbances and respiratory disorders such as URTI (Upper Respiratory Tract Infection). According to data from Badan Pusat Statistik Kota Padang in 2018, URTI represents the highest complaint in the district Lubuk Begalung as many as 5,534 cases (28%). In the district has industrial and transportation activities which are a source of air pollution. However, in there haven’t real time monitoring of air pollution, so it is necessary to carry out air pollution simulations. This study aims to determine the concentration of TSP ambient air pollution and to analyze the distribution air pollutant in the Lubuk Begalung District, Padang City. The research method used a quantitative, where the emission inventory and meteorological data used the Gauss dispersion model and surver 15 software. The maximum TSP from measurement and modeling results was 113.42 µg/m3 and 27.16 µg/m3. This result explain about the TSP concentration is still below the National BMUA in PP RI No. 41 of 1999, which is 230 µg/m3 (still in good condition). This is different from previous studies because this study only considers sources of industrial emissions without other sources of pollution. The result of the TSP distribution is moving increasingly towards the Southwest from the emission source and reaches a maximum concentration at the coordinate point (-0.98103 oS, 100.34567 oE), according to the dominant wind direction.

Abstract

Employing Hot Mix Asphalt (HMA) technology for asphalt pavement construction results in the emission of greenhouse gases and other harmful pollutants, contributing to significant air pollution due to extensive energy consumption. Consequently, the adoption of Warm Mix Asphalt (WMA) is recommended, given its potential for enhanced energy efficiency and reduced emissions due to lower mixing and production temperatures compared to HMA. This research delves into the impact of incorporating waste motor engine oil (WMEO) as a bitumen modifier in warm mix asphalt. The investigation involved adding WMEO at various percentages, specifically 0%, 3%, 4%, and 5% based on the weight of bitumen. The study assessed the performance of the samples in terms of penetration, softening point, stability, flow, and stiffness. The findings revealed that the incorporation of WMEO in warm mix asphalt led to a substantial improvement in penetration and softening point. Moreover, the results indicated that incorporating WMEO as a bitumen modifier could enhance the performance of WMA in terms of stability, flow, and stiffness.

Abstract

Effective energy conservation strategies are required to be implemented in academic buildings as they consume significant energy while considering the convenience and function of the buildings. However, the influencing factors are interrelated and complex, requiring an appropriate approach to unravel the complexity. Therefore, this study aims to identify, analyse, and map the interaction relationship between factors affecting energy conservation in academic buildings. This study used Interpretive Structural Modeling (ISM) procedure starting from developing the Structural Self Interaction Matrix (SSIM), converting SSIM into a Reachability Matrix, revising the matrix, and categorizing the factors by using MICMAC analysis. This study involved 9 factors, including architectural design, illumination technology, education and awareness, energy monitoring and management, renewable energy use, efficient HVAC system, energy-saving equipment, institutional policies, and campus community participation. The study found that renewable energy use at level 3 was the factor that was not influenced by and did not interact with any other factors. Meanwhile, the illumination technology was a factor that interacted with the efficient HVAC System factor which was at level 1 where these two factors were influenced by other seven factors. This study aligns with current developments in energy conservation, including an increased focus on renewable energy and energy efficiency in academic buildings, supported by global and national policies aimed at achieving sustainability goals. It provides a comprehensive understanding on developing sustainable energy conservation strategies in academic buildings.

Abstract

Mikroplastik adalah plastik berukuran kurang dari 5 mm yang berasal dari degradasi sampah plastik dilingkungan. Mikroplastik telah ditemukan pada air laut dan berpotensi terkonsumsi oleh beberapa organisme laut hingga mencapai manusia melalui rantai makanan. Penelitian ini dilakukan untuk mengidentifikasi karakteristik fisik mikroplastik dan menentukan kelimpahan mikroplastik pada air laut Pantai Pariaman. Karakteristik mikroplastik yang diidentifikasi yaitu kelimpahan, bentuk, warna dan ukuran mikroplastik. Sampel air laut diambil pada stasiun 1 (Gedung Pentas Seni Pantai Kata), stasiun 2 (Pantai Cermin), stasiun 3 (Pantai Gandoriah), stasiun 4 (Kawasan Hutan Mangrove) dengan frekuensi dua kali pengujian pada titik yang sama. Kelimpahan mikroplastik pada sampel dengan menghitung jumlah partikel mikroplastik per satuan volume sampel air laut. Karakteristik bentuk, ukuran dan warna di identifikasi menggunakan mikroskop. Kelimpahan mikroplastik rata-rata adalah 27,5 - 85 partikel/L. Mikroplastik yang dominan ditemukan adalah bentuk fiber dengan persentase 52%. Warna dominan yang ditemukan adalah warna hitam dengan persentase 30% dan Ukuran mikroplastik yang dominan ditemukan adalah 0,5 – 1 mm dengan persentase 42 %.

Abstract

Jalan Nasir Pamuncak adalah ruas jalan nasional yang vital di Kota Solok dan mengalami berbagai kerusakan. Penelitian ini bertujuan menganalisis tingkat kerusakan dan kondisi jalan untuk menentukan rekomendasi perbaikan. Penelitian ini menggunakan metode kuantitatif dengan dua pendekatan yaitu metode Asphalt Institute untuk menilai jenis serta luas kerusakan secara visual dan metode International Roughness Index (IRI) menggunakan aplikasi RoadLab Pro untuk mengukur ketidakrataan permukaan. Berdasarkan hasil analisis metode Asphalt Institute diperoleh total kerusakan sebesar 10,665% dengan nilai kondisi perkerasan sebesar 89,334% yang menunjukkan bahwa kondisi jalan tergolong baik dan memerlukan pemeliharaan rutin. Sementara itu, hasil pengukuran menggunakan metode IRI menunjukkan nilai rata-rata sebesar 4,58 m/km yang mengindikasikan bahwa kondisi jalan termasuk dalam kategori sedang dan memerlukan pemeliharaan berkala. Perbedaan hasil antara kedua metode menunjukkan pentingnya penggunaan pendekatan ganda untuk memperoleh gambaran kondisi jalan yang lebih komprehensif serta menentukan jenis penanganan yang tepat agar kinerja jalan tetap optimal.
