Abstract

Abstrak Aspal porus merupakan campuran beraspal yang memiliki rongga udara yang besar yang menyebabkan aspal porus memiliki nilai stabilitas yang rendah. Untuk meningkatkan nilai stabilitas diperlukan bahan tambah lain yang memiliki potensi seperti limbah Abu Cangkang Tiram (OSA) dan limbah High Density Polyethylene (HDPE). OSA mempunyai sifat kimia yang mengandung kapur dan silika yang berfungsi untuk keawetan dan mengunci antar agregat pada perkerasan jalan. Sedangkan HDPE memiliki kekuatan yang tinggi dan kaku serta perilaku untuk mengikat sehingga dapat memperkuat ikatan antara agregat dan OSA dan menambah perkuatan terhadap campuran aspal porus. Tujuan penelitian ini adalah untuk menentukan Kadar Aspal Optimum (OAC) pada campuran aspal porus, dan menganalisis variasi persentase terbaik OSA dan limbah HDPE sebagai substitusi aspal pen 60/70. Pengujian yang dilakukan adalah pemeriksaan terhadap parameter Marshall. Hasil penelitian menunjukkan bahwa variasi filler 50% OSA : 50% PC dengan 4%, 6% HDPE dapat meningkatkan nilai stabilitas Marshall pada campuran aspal porus serta memenuhi spesifikasi Australian Asphalt Pavement Association (AAPA). Kata kunci: aspal porus, marshall, abu cangkang tiram, HDPE   Abstract Porous Asphalt is the asphalt mix containing large air void resulting low stability of porous asphalt.

Abstract

Abstract: The drainage channel is one of the complementary buildings on the road segment in requiring one of the technical requirements for road infrastructure. The road drainage channels in general are open channels using gravity to drain surface water or inundation to the channel. The distribution of flow in the drainage channel to this channel follows the contours of the highway so that the water will flow easily following gravity. The Several alternatives selection of drainage development technologies include elbow drainage, parallel, grid iron, natural and radial. The problem found that some factor considered in selection the right technology are the construction budget, construction period, material supply, and construction process affecting the selection process become complicated. The purpose of this study is to determine the dominant criteria required in considering the selection of drainage construction technology in Banda Aceh and to determine the proper alternative using Analytical Hierarchy Process (AHP) method. After distributing questionnaires to 16 respondents, the research found that the dominant criterion is the construction period as the score of 0.66. According to the respondents, the construction period become the most vital criteria since the assessment of criteria variable relate to the limitation in complete all drainage proposed. This study founds that the best alternative in selecting drainage construction technology is "parallel drainage" as the score is 4.96. Therefore, this study recommends the use of "parallel drainage" as a priority in the drainage construction Banda Aceh by considering construction budget, construction period, material supply and construction process.Abstrak: Saluran drainase merupakan salah satu bangunan pelengkap pada ruas jalan dalam memenuhi salah satu persyaratan teknis prasarana jalan. Pada umumnya saluran drainase jalan merupakan saluran terbuka yang menggunakan gaya gravitasi untuk mengalirkan air limbah ke outlet. Distribusi aliran di saluran drainase ke outlet ini mengikuti kontur jalan raya sehingga air limbah akan lebih mudah mengalir secara gravitasi. Beberapa alternatif pemilihan teknologi pembangunan drainase antara lain adalah drainase elbow, parallel, gridiron, natural dan radial. Persoalannya, beberapa faktor yang perlu dipertimbangkan dalam memilih teknologi yang tepat, biaya pembangunan, waktu konstruksi, ketersediaan material, dan proses pembangunan sehingga pilihan menjadi rumit. Tujuan dari penelitian ini adalah untuk menentukan kriteria dominan yang perlu diperhatikan dalam pemilihan teknologi pembangunan drainase di Kota Banda Aceh dan menentukan alternatif yang tepat melalui metode Analytical Hierarchy Process (AHP). Setelah menyebarkan kuesioner kepada 16 responden, penelitian menemukan bahwa kriteria yang dominan adalah waktu pengerjaan dengan bobot tertinggi (0,66). Menurut responden, waktu konstruksi merupakan kriteria yang paling penting karena keterbatasan dalam menyelesaikan seluruh usulan pembangunan drainase perlu dipertimbangkan. Studi ini menemukan bahwa alternatif terbaik dalam memilih teknologi pembangunan drainase adalah “drainase paralel” yang memperoleh nilai kinerja tertinggi sebesar 4,96. Oleh karena itu, penelitian ini merekomendasikan penggunaan “drainase paralel” sebagai prioritas dalam pembangunan drainase di Kota Banda Aceh dengan pertimbangan biaya, waktu konstruksi, ketersediaan material, dan proses pembangunan.

This study aims to analyze the influence of perceived benefits on users' health awareness among wearable device users in Banda Aceh City. Aim. This study aims to analyze association of perceived benefits on users' health awareness among wearable device users in Banda Aceh City. Method. This research applied a descriptive quantitative design with a cross-sectional approach. Data were collected using a questionnaire from 106 active wearable device users engaging in physical activity at Harapan Bangsa Stadium and Blang Padang Field, Banda Aceh. Respondents were selected using purposive sampling. Data were analyzed using logistic regression with STATA17.0. Result. The results indicated that the type of wearable device did not significantly affect users’ health awareness (OR = 0.766; P = 0.562). However, device features (OR = 55.5; P = 0.000), comfort in use (OR = 46.6; P = 0.000), and usage frequency (OR = 4.06; P = 0.004) showed a significanteffect. Conclusion. The conclusion is that the features, comfort, and frequency of use of wearable devices have a significant impact on users' health awareness, whereas the type of device does not.

Abstract

Abstract: Dam failure is a critical hydrological hazard with potentially severe impacts on downstream communities and infrastructure. This study analyzes dam break impacts and mitigation strategies using two-dimensional hydraulic modeling with HEC-RAS 2D, integrated with Geographic Information System (GIS)-based spatial analysis, at the Kerinci Merangin Hydropower Dam in Jambi Province, Indonesia. Overtopping and piping failure scenarios were simulated to estimate peak discharge, inundation extent, flow velocity, and flood wave arrival time, which directly informed the design of a site-specific Emergency Action Plan (EAP). Simulation results indicate that a complete dam failure could generate a peak discharge of approximately 681.5 m³/s, with flood waves reaching high-risk downstream areas within only 15-20 minutes. GIS-based hazard mapping reveals that several critical access and evacuation routes are located within high-inundation zones, limiting conventional evacuation feasibility. A sensitivity analysis of key hydraulic parameters, including breach geometry and Manning’s roughness coefficient, demonstrates that small parameter variations significantly affect flood arrival time and evacuation lead-time reliability. The study’s contribution lies in demonstrating how sensitivity-informed dam break modeling can identify evacuation constraints and support the development of a highly localized, rapid-response EAP, moving beyond generic mitigation frameworks toward operationally feasible disaster preparedness. Abstrak: Kegagalan bendungan merupakan bahaya hidrologi yang kritis dengan potensi dampak yang serius terhadap masyarakat dan infrastruktur di wilayah hilir. Penelitian ini menganalisis dampak keruntuhan bendungan dan strategi mitigasi menggunakan pemodelan hidraulik dua dimensi dengan HEC-RAS 2D yang terintegrasi dengan analisis spasial berbasis Sistem Informasi Geografis (SIG), dengan studi kasus Bendungan PLTA Kerinci Merangin di Provinsi Jambi, Indonesia. Skenario kegagalan akibat overtopping dan piping disimulasikan untuk mengestimasi debit puncak, luas genangan, kecepatan aliran, serta waktu kedatangan gelombang banjir yang secara langsung digunakan sebagai dasar penyusunan Rencana Tindakan Darurat (Emergency Action Plan/EAP) yang bersifat spesifik lokasi. Hasil simulasi menunjukkan bahwa kegagalan total bendungan dapat menghasilkan debit puncak sekitar 681,5 m³/detik, dengan gelombang banjir mencapai wilayah hilir berisiko tinggi hanya dalam waktu 15-20 menit. Pemetaan bahaya berbasis SIG mengungkap bahwa beberapa jalur akses dan evakuasi kritis berada dalam zona genangan tinggi, sehingga membatasi kelayakan evakuasi konvensional. Analisis sensitivitas terhadap parameter hidraulik utama, termasuk geometri rekahan dan koefisien kekasaran Manning, menunjukkan bahwa variasi parameter yang relatif kecil dapat secara signifikan memengaruhi waktu kedatangan banjir dan keandalan waktu evakuasi. Kontribusi utama penelitian ini terletak pada demonstrasi bagaimana pemodelan keruntuhan bendungan yang mempertimbangkan analisis sensitivitas dapat mengidentifikasi keterbatasan evakuasi dan mendukung penyusunan EAP yang sangat terlokalisasi dan berorientasi pada respons cepat, melampaui kerangka mitigasi generik menuju kesiapsiagaan bencana yang lebih operasional dan realistis.
