Abstract

Buildings subjected to horizontal vibration loading can cause displacement deformation and even collapse. Laboratory-scale testing to simulate vibrations due to horizontal loading can be done using structural modeling using a shaking table as the vibration source medium. This can be done because large-scale testing is very difficult to do due to cost and time constraints. This study aims to analyze the impact of bracing use on the response of Single Degree of Freedom (SDOF) and Multi Degree of Freedom (MDOF) structures due to horizontal vibration loads. The building models tested were one to three-story models with and without bracing. Testing was carried out using a one-way horizontal shaking table with varying frequencies of 15 Hz, 20 Hz, and 25 Hz to see the differences in each structural response. The parameters observed in this study were model displacement and acceleration. The study results show that the model without bracing experiences a maximum acceleration at each vibration table frequency of 490 cm/s2 with a vibration table frequency of 15 Hz, 649 cm/s2 with a vibration table frequency of 20 Hz, and 774 cm/s2 with a vibration table frequency of 25 Hz. Meanwhile, the model using bracing experiences the largest acceleration reduction of up to 35% for a vibration table frequency of 25 Hz. Bracing increases the lateral stiffness of the structure thereby reducing deformation to be smaller than the structure without bracing. The maximum displacement value of the model without bracing at each frequency is 1.08 cm at a vibration table frequency of 15 Hz, 1.54 cm at a vibration table frequency of 20 Hz, and 2.84 cm at a vibration table frequency of 25 Hz. From the study conducted, it can be concluded that the use of bracing in SDOF and MDOF structures has a reduction in structural response of up to 35%.

Abstract

Korosi pada baja struktural menimbulkan kerugian ekonomi yang besar dan menjadi tantangan teknis yang signifikan, terutama di wilayah tropis dengan tingkat kelembapan tinggi seperti Indonesia. Berbagai metode perlindungan korosi telah dikembangkan, namun kajian komprehensif yang membandingkan efektivitas masing-masing metode masih terbatas. Penelitian ini menggunakan pendekatan scoping review dengan mengacu pada kerangka Arksey dan O’Malley. Sebanyak 70 artikel diidentifikasi dari enam basis data elektronik untuk periode publikasi 2015–2026. Setelah penghapusan artikel duplikat serta proses penyaringan judul, abstrak, dan teks lengkap berdasarkan kriteria inklusi dan eksklusi, diperoleh 26 artikel yang digunakan dalam sintesis akhir. Data dianalisis secara naratif dan dikelompokkan ke dalam empat metode utama, yaitu lapisan polimer, perlindungan katodik, inhibitor korosi, dan perlakuan permukaan. Hasil kajian menunjukkan bahwa setiap metode memiliki keunggulan dan keterbatasan yang dipengaruhi oleh kondisi lingkungan, karakteristik struktur, kebutuhan pemeliharaan, serta aspek ekonomi dan keberlanjutan. Tidak terdapat satu metode yang unggul secara mutlak untuk seluruh kondisi. Oleh karena itu, pemilihan sistem perlindungan korosi perlu dilakukan secara komprehensif dan disesuaikan dengan kondisi paparan, karakteristik material, umur layan, serta kebutuhan spesifik struktur yang dilindungi.

Abstract

Simpang Ayam Village is located in Bengkalis District, Bengkalis Regency, Riau Province. This coastal area consists of peatland and faces the Malacca Strait, making it vulnerable to wave-induced abrasion. At the end of 2022, a significant landslide occurred in Simpang Ayam Village, causing substantial shoreline changes and resulting in the loss of dozens of hectares of land to the sea. Conducting manual investigations in the landslide-affected area is not feasible due to continuous land movement towards the sea, posing serious safety risks. Remote sensing technology offers an effective method to analyze shoreline changes using the Modified Normalized Difference Water Index (MNDWI) and vegetation density changes through the Normalized Difference Vegetation Index (NDVI). This study utilizes Sentinel-2 medium-resolution satellite imagery to assess these changes. The results indicate a noticeable shift in the shoreline, marked by landward advancement, and a decline in vegetation density, as evidenced by a vegetation index decrease of more than -0.1. Furthermore, the total landslide-affected area was 36.89 hectares, with the largest landslide occurring at Location 3 (15.96 hectares) and the smallest at Location 9 (0.49 hectares).

Abstract

Sungai Rokan merupakan salah satu wilayah sungai strategis di Provinsi Riau yang berperan penting dalam pemenuhan kebutuhan air domestik, pertanian, dan industri. Peningkatan pemanfaatan air sebagai materi menuntut sistem perizinan yang berbasis pada ketersediaan sumber daya air guna menjamin keberlanjutan hidrologis. Penelitian ini bertujuan mengevaluasi kesesuaian pemberian izin pemakaian air sebagai materi terhadap neraca ketersediaan air Sungai Rokan periode 2012–2021. Analisis dilakukan menggunakan pendekatan neraca air dengan metode NRECA untuk estimasi debit andalan (Q80, Q90, dan Q95), serta perbandingan terhadap total kebutuhan air dari sepuluh perusahaan pemegang izin. Hasil penelitian menunjukkan bahwa debit ketersediaan Sungai Rokan pada musim kering mencapai ±74,665 m³/det, musim normal ±355 m³/det, dan musim basah ±978,008 m³/det. Total kebutuhan air industri sebesar ±1,7 m³/det masih berada jauh di bawah debit andalan musim kering. Temuan ini mengindikasikan bahwa secara kuantitatif pemberian izin masih berada dalam kondisi surplus neraca air. Novelty penelitian ini terletak pada integrasi evaluasi perizinan berbasis regulasi nasional dengan pendekatan kuantitatif neraca air jangka 10 tahun sebagai dasar objektif pengambilan keputusan izin pemanfaatan air sungai kewenangan pusat.
