Abstract

Abstrak   Proyek konstruksi sering menghasilkan waste material, yaitu material sisa yang tidak dapat langsung digunakan kembali tanpa perlakuan tambahan. Dari berbagai jenis material, besi tulangan sering menghasilkan sisa dalam jumlah yang cukup besar, hal ini disebabkan karena perubahan desain, kesalahan perencanaan, dan pemotongan yang tidak optimal. Untuk meminimalisasi waste tersebut, dilakukan optimasi penggunaan tulangan melalui pemodelan pada Autodesk Revit untuk menghasilkan rebar schedule, yang kemudian diolah menggunakan Cutting Optimization Pro untuk menentukan pola pemotongan paling efisien. Penelitian ini difokuskan pada pekerjaan struktur bawah Jembatan No.8 Proyek Jalan Tol Akses Patimban Paket 1. Hasil dari penelitian yaitu, waste material dapat ditekan hingga 3,55%, dengan rincian D13 sebesar 0%, D16 sebesar 0,46%, D19 sebesar 1,01%, dan D32 sebesar 2,08%. Total waste cost mencapai Rp138.364.599,96, dengan D32 sebagai penyumbang biaya terbesar. Pengelolaan sisa material dilakukan melalui strategi recycle dan salvage untuk mendukung efisiensi serta keberlanjutan konstruksi.   Kata kunci: waste material, besi tulangan, minimalisasi, waste cost       Abstract   Construction projects often generate waste material, which refers to leftover materials that cannot be reused without additional processing. Among various materials used, reinforcing steel (rebar) often produces a significant amount of waste due to design changes, planning errors, and suboptimal cutting processes. To minimize this waste, rebar usage is optimized through modeling in Autodesk Revit to produce a rebar schedule, which is then processed using Cutting Optimization Pro to determine the most efficient cutting pattern. This study focuses on the Substructure Work of Bridge No. 8 in the Patimban Access Toll Road Project Package 1. The results show that waste material can be reduced to 3.55%, with waste percentages of 0% for D13, 0.46% for D16, 1.01% for D19, and 2.08% for D32. The total waste cost reached Rp138,364,599.96, with D32 contributing the highest cost. Waste management was carried out through recycling and salvage strategies to support efficiency and construction sustainability.   Keywords: waste material, reinforcing steel, minimization, waste cost

One potential recycling approach is its utilization as a partial substitute for asphalt. The AC-WC (Asphalt Concrete–Wearing Course) layer is the uppermost pavement layer, functioning as a wearing course, and consists of coarse aggregate, fine aggregate, filler, and asphalt binder. The use of HDPE (High Density Polyethylene) and LDPE (Low Density Polyethylene) plastics as partial replacements for asphalt in AC-WC mixtures aims to improve stability values compared to conventional asphalt and to act as a thermoplastic binder between aggregates. This study aims to evaluate variations in the use of HDPE and LDPE plastics that satisfy Marshall parameter requirements. A total of 15 specimens were prepared to determine the Optimum Asphalt Content (OAC), while 3 specimens were tested for each plastic variation of 5%, 6%, and 7%. Marshall testing was conducted, and the OAC was found to be 6%. The results indicate that all Marshall parameters meet the specified requirements. It can be concluded that partial substitution of asphalt with HDPE and LDPE plastics at 5%, 6%, and 7% variations complies with the 2018 Bina Marga General Specifications (Revision 2).   Keywords: Laston AC-WC, Marshall Parameters, HDPE Plastic, LDPE Plastic

Abstract

Abstrak   Beton ready mix banyak digunakan pada proyek konstruksi berskala menengah hingga besar, terutama pada struktur yang terpapar air dan lingkungan agresif. Selain memenuhi kuat tekan rencana, beton juga dituntut memiliki kinerja kekedapan yang baik. Penelitian ini bertujuan mengevaluasi pengaruh penambahan admixture integral waterproofing terhadap kuat tekan dan penetrasi air pada beton ready mix proyek di Bakauheni, Lampung Selatan. Beton mutu rencana f’c 24,9 MPa diuji dalam tiga variasi: tanpa admixture, dengan admixture integral waterproofing, dan kombinasi admixture dengan finishing coating. Uji kuat tekan dilakukan pada umur 28 dan 56 hari dengan perendaman air tawar dan air laut, sedangkan uji penetrasi air dilakukan pada umur 28 hari. Analisis menggunakan metode deskriptif dan ANOVA (α = 5%). Hasil menunjukan seluruh variasi melampaui kuat tekan rencana dan admixture tidak berpengaruh signifikan terhadap kuat tekan. Namun, kombinasi admixture dan coating secara signifikan menurunkan penetrasi air sesuai SNI 03-2914-1992.   Kata kunci: Beton ready mix, admixture integral waterproofing, kuat tekan beton, penetrasi air, beton kedap air   Abstrack   Ready-mix concrete is widely used in medium- to large-scale construction projects, particularly for structures exposed to water and aggressive environments. In such conditions, concrete is required not only to achieve the specified compressive strength but also to provide adequate watertight performance. This study aims to evaluate the effect of integral waterproofing admixture on compressive strength and water penetration depth of ready-mix concrete used in an actual construction project in Bakauheni, Lampung Selatan. Concrete with a design strength of f’c 24.9 MPa was tested under three variations: without admixture, with integral waterproofing admixture, and with integral waterproofing admixture combined with a finishing coating. Compressive strength tests were conducted at 28 and 56 days under freshwater and seawater immersion, while water penetration tests were performed at 28 days. Data were analyzed using descriptive analysis and two-way ANOVA (α = 5%). Results indicate that all variations exceeded the design strength, and the admixture had no significant effect on compressive strength. However, the combination of admixture and coating significantly reduced water penetration depth in accordance with SNI 03-2914-1992.   Keywords: Ready-mix concrete, integral waterproofing admixture, compressive strength, water penetration, waterproof concrete

Abstract

Abstrak Daerah Irigasi Sekampung  masih bergantung pada suplai air dari Bendungan Batutegi hingga Bendung Argoguruh. Penelitian ini bertujuan untuk mengevaluasi alokasi air tahunan pada sistem irigasi Sekampung Sistem. Analisis dilakukan menggunakan data debit terukur periode 2014–2023, pola tanam, dan kebutuhan air PDAM. Ketersediaan air dianalisis menggunakan debit andalan 33,33%, 50%, dan 66,67% pada skenario tahun basah, normal, dan kering. Hasil penelitian menunjukkan kebutuhan air didominasi oleh sektor irigasi dengan nilai 79,23 m³/dt pada puncak musim tanam, sedangkan kebutuhan air baku PDAM bersifat relatif konstan sebesar 0,93 m³/dt sepanjang tahun. Neraca air mengindikasikan bahwa defisit air masih terjadi pada periode Januari hingga Maret pada seluruh skenario hidrologi, sementara kondisi surplus terjadi pada periode Oktober–Desember serta April–September. Temuan ini menunjukkan pengelolaan alokasi air tahunan yang adaptif dan berbasis neraca air diperlukan untuk memanfaatkan periode surplus sebagai cadangan guna mengantisipasi defisit dan menjamin keberlanjutan pelayanan irigasi dan air baku.   Kata kunci: Daerah Irigasi Sekampung; kebutuhan air; ketersediaan air; neraca air; debit andalan   Abstrack The Sekampung Irrigation Area is dependent on water supply from Batutegi Dam to Argoguruh Weir. This study aims to evaluate the annual water allocation in the Sekampung Irrigation System. The analysis was conducted using measured discharge data from 2014–2023, cropping patterns, and PDAM raw water demand data. Water availability was assessed using dependable discharge values of 33,33%, 50%, and 66,67% to represent wet, normal, and dry year scenarios, respectively. The results show that water demand is dominated by the irrigation sector, reaching 79,23 m³/s at the peak of the planting season, while PDAM raw water demand remains relatively constant at 0,93 m³/s throughout the year. The water balance analysis indicates that deficits occur during January–March under all hydrological scenarios, whereas surplus conditions occur during October–December and April–September. These findings highlight the need for adaptive annual water allocation management based on water balance analysis to optimize surplus periods as reserves, anticipate deficits, and ensure sustainable irrigation and raw water services.   Keywords: Sekampung Irrigation System, water demand; water availability, water balance, dependable flow

Abstract

Abstrak   Risiko longsor di wilayah tropis dipicu interaksi iklim dan topografi, namun kajian sistematis yang memadukan keduanya dengan Digital Elevation Model (DEM) masih terbatas. Studi ini menelaah faktor pemicu dan pemanfaatan DEM dalam analisis kerentanan. Metodologi menggunakan analisis tematik terhadap 19 artikel (2015-2025) dari Google Scholar dan Scopus. Hasil menunjukkan lereng curam dan hujan intensitas tinggi sebagai pemicu dominan, terutama di kawasan bergunung. Secara keseluruhan, risiko longsor di wilayah tropis yang dikaji didominasi kategori kerawanan sedang hingga sangat tinggi. DEM terbukti efektif mengekstraksi parameter elevasi, kemiringan, dan aliran. Metode Frequency Ratio dan Analytic Hierarchy Process mencapai akurasi tertinggi (Area Under Curve/AUC 0,90-0,91), diikuti Random Forest (0,85). Kajian ini menyintesis temuan iklim-topografi tropis dan mengidentifikasi celah penelitian terkait integrasi data hujan temporal, resolusi DEM, serta validasi lapangan.   Kata kunci: Longsor, Curah Hujan, Topografi, Digital Elevation Model, Studi Literatur Sistematis       Abstrack   Landslide risk in tropical regions is driven by climatic and topographic interactions, yet systematic studies integrating both with Digital Elevation Model (DEM) data remain limited. This systematic review examines landslide triggers and DEM utilization in vulnerability analysis. The methodology involves a thematic analysis of 19 articles (2015-2025) from Google Scholar and Scopus. Results identify steep slopes and high-intensity rainfall as dominant triggers, particularly in complex mountainous areas. Overall, landslide risk in the studied tropical regions is predominantly categorized as moderate to very high. DEM effectively extracts elevation, slope, and flow parameters. Frequency Ratio and Analytic Hierarchy Process achieved the highest accuracy (Area Under Curve/AUC 0.90-0.91), followed by Random Forest (0.85). This study synthesizes tropical climate-topography findings and identifies research gaps regarding temporal rainfall integration, DEM resolution, and field validation.   Keywords: Landslide, Rainfall, Topography, Digital Elevation Model, Systematic Literature Review

Abstract

Abstrak   Wilayah pesisir memiliki potensi besar bagi pembangunan ekonomi, sosial, dan ekologi, namun pemanfaatannya masih terbatas dan menghadapi tekanan lingkungan yang meningkat. Di Provinsi Aceh, kawasan pesisir semakin rentan akibat perubahan iklim dan aktivitas manusia yang memicu kenaikan muka air laut, peningkatan frekuensi badai, abrasi, serta banjir rob. Salah satu wilayah yang terdampak adalah Pantai Susoh di Kabupaten Aceh Barat Daya yang memiliki fungsi penting sebagai kawasan wisata dan religius. Namun, abrasi terjadi hampir setiap tahun dan pada Oktober 2023 gelombang pasang akibat anomali iklim merusak lebih dari selusin rumah penduduk. Kondisi ini diperparah oleh banjir rob yang dipengaruhi penurunan muka tanah pasca gempa 2004. Penelitian ini menggunakan pemodelan numerik dengan metode morphological scale factor (morfac) untuk menganalisis kondisi eksisting dan memprediksi dinamika morfologi pantai jangka panjang. Hasil simulasi menunjukkan tren erosi berkelanjutan hingga 50 tahun mendatang dengan kemunduran garis pantai rata-rata ±200,19 m. Oleh karena itu, strategi mitigasi berbasis struktur pantai dan rehabilitasi ekosistem diperlukan untuk mengurangi risiko abrasi dan mendukung pengelolaan pesisir yang berkelanjutan.   Kata kunci: erosi pantai, mitigasi pesisir, morfac, pemodelan numerik, perubahan iklim   Abstrack   Coastal areas have significant potential for economic, social, and ecological development; however, their utilization remains limited and increasingly pressured by environmental changes. In Aceh Province, coastal regions are becoming more vulnerable due to climate change and human activities that contribute to sea level rise, increased storm frequency, coastal erosion, and tidal flooding. One of the affected areas is Susoh Beach in Southwest Aceh Regency, which plays an important role as a tourism and religious area. However, coastal erosion occurs almost every year, and in October 2023 storm surges triggered by climate anomalies damaged more than a dozen houses. This condition is further exacerbated by tidal flooding influenced by land subsidence following the 2004 earthquake. This study employs numerical modeling using the morphological scale factor (morfac) method to analyze existing conditions and predict long-term coastal morphological dynamics. The simulation results indicate a continuous erosion trend over the next 50 years, with an average shoreline retreat of approximately ±200.19 m. Therefore, mitigation strategies based on coastal protection structures and ecosystem rehabilitation are necessary to reduce erosion risk and support sustainable coastal management.   Keywords: Coastal erosion, coastal mitigation, morfac, numerical modeling, climate change

Abstract

Abstrack   This study aims to analyze the determinants of flow connectivity in small-scale irrigation networks within wetland ecosystems of Aceh Jaya Regency, based on the perceptions of 135 water users. Five primary parameters were evaluated: channel structural stability (X1), channel conveyance condition (X2), sedimentation (X3), flow connectivity (X4), and discharge control performance (X5). Integration of Spearman correlation, ordinal logistic regression, Sobol’ sensitivity analysis, and cluster analysis reveals that canal conveyance condition (X2) performs best. Channel structural stability (X1) shows the lowest performance as a direct impact of wetland characteristics. Unstable soil conditions exacerbate the physical stability of irrigation networks in the region.Correlation findings reveal that cross-sectional stability is significantly and positively related to connectivity (r=0.452), while discharge control performance (X5) shows a negative correlation (r=-0.513). A reverse causality phenomenon is indicated in locations with high water distribution constraints, where control infrastructure tends to be concentrated. Regression analysis confirms that good cross-sectional stability increases the probability of optimal connectivity by up to 2.6 times. Sensitivity analysis results identify flow control as the most critical parameter (STi=0.51), followed by cross-sectional stability (STi=0.44). This research recommends priority interventions in strengthening control infrastructure and cross-sectional stability adaptive to wetland hydrological dynamics based on a farmer cluster approach.   Keywords: Small-scale Irrigation Networks, Flow Connectivity, Wetlands, Sobol’ Sensitivity Analysis   Abstrak   Penelitian ini bertujuan menganalisis determinan konektivitas aliran pada jaringan irigasi skala kecil di lahan basah Kabupaten Aceh Jaya berdasarkan persepsi 135 petani. Lima parameter utama dievaluasi meliputi stabilitas penampang (X1), kebersihan saluran (X2), sedimentasi (X3), konektivitas aliran (X4), dan pengendalian aliran (X5). Melalui integrasi korelasi Spearman, regresi logistik, sensitivitas Sobol’, dan analisis klaster, ditemukan bahwa kebersihan saluran (X2) berkinerja terbaik, sedangkan stabilitas penampang (X1) terlemah akibat kondisi tanah lahan basah yang labil. Hasil korelasi menunjukkan X1 berhubungan positif signifikan dengan X4 (r=0,452), sementara X5 berkorelasi negatif (r=-0,513), mengindikasikan fenomena kausalitas terbalik pada area dengan kendala distribusi air tinggi. Analisis regresi mengonfirmasi bahwa peningkatan kondisi X1 meningkatkan peluang konektivitas aliran (X4) hingga 2,6 kali lipat. Analisis sensitivitas menempatkan pengendalian aliran (X5) sebagai parameter paling kritis (STi=0,51), diikuti X1 (STi=0,44). Penelitian ini merekomendasikan prioritas intervensi pada infrastruktur pengendalian dan stabilisasi penampang yang adaptif terhadap dinamika hidrologi lahan basah berbasis pendekatan klaster petani.   Kata kunci: Jaringan Irigasi Kecil, Konektivitas Aliran, Lahan Basah, Sensitivitas Sobol’
