Abstract

Abstrak Limbah Konstruksi dihasilkan adanya pembangunan infrastruktur yang memberikan dampak negatif terhadap lingkungan. Pesatnya pembangunan infrastruktur di Indonesia tentunya hal ini juga akan menghasilkan limbah konstruksi yang jumlahnya banyak dan cepat penambahannya. Sumber limbah konstruksi bisa dalam bentuk padat, cair, gas atau kombinasi dari semua bentuk tersebut. Proyek konstruksi merupakan penghasil limbah padat yang sangat besar. Manajemen pengelolaan dan pemanfaatan limbah konstruksi perlu dilaksanakan secara seksama, Indonesia merupakan negara berkembang yang laju pembangunan infrastrukturnya sangat pesat sekarang ini tetap mendukung pencapaian SDGs Agenda 2030, salah satu SDGs adalah Zero Waste Project dengan melaksanakan prinsip œThe 6 Rs of sustainability. Beberapa penelitian sebelumya terkait pemanfaatan abu batu digunakan sebagai penganti agregat halus campuran pembuat beton. Mengacu penelitiaan sebelumnya terkait pemanfaatan abu batu belum terdapat pemanfaatan abu batu digunakan sebagai material pengganti lapis drainase pada pondasi pekerasan jalan beton, sehingga masih terdapat gap pada penelitian sebelumnya yang akan dilakukan penelitian ini. Kata Kunci: Limbah Konstruksi, Abu Batu, Lapis Drainase, Perkerasan Beton  Abstract Construction waste is generated by infrastructure development that has a negative impact on the environment. The rapid development of infrastructure in Indonesia will certainly also produce construction waste in large quantities and increasing rapidly. Sources of construction waste can be in the form of solid, liquid, gas or a combination of all these forms. Construction projects are very large producers of solid waste. Management of construction waste management and utilization needs to be carried out carefully, Indonesia is a developing country with a very rapid rate of infrastructure development currently still supporting the achievement of the SDGs Agenda 2030, one of the SDGs is the Zero Waste Project by implementing the principle of "The 6 Rs of sustainability". Several previous studies related to the utilization of stone ash were used as a substitute for fine aggregate in concrete mixtures. Referring to previous studies related to the utilization of stone ash, there has been no use of stone ash as a substitute material for drainage layers on concrete road pavement foundations, so there is still a gap in previous research that will be carried out in this study. Keyword: Construction waste, Stone Ash, Drainage Layer, Concrete Pavement

Abstract

This paper presents a comprehensive study of the dynamic responses of machine foundations, both block and pile foundations, on stratified residual soils in Duri and Ulubelu, Indonesia. The evaluation was conducted using two widely recognized methods: the lumped mass method (LMM) and the finite element method (FEM). LMM and FEM were performed by utilizing DYNA and ABAQUS, respectively. The analysis results showed that LMM generally predicted more conservative displacements compared to FEM. This conservatism in predicted displacement was more pronounced for pile group foundations, which are inherently more flexible than block foundations. Additionally, this study found that the resonance frequencies obtained through both analysis methods were not the same. Furthermore, this paper includes a parametric study and presents its results to assess the influence of key factors, i.e., pile cap thickness, pile diameter, number of piles, and vertical dynamic loads, on displacement.

Abstract

Penelitian ini dilakukan pada Bendungan Sadawarna yang menunjukkan indikasi rembesan dan tekanan uplift pada tubuh bendungan, sehingga diperlukan tindakan mitigasi melalui pembangunan counterweight sebagai upaya perkuatan. Studi ini bertujuan untuk mengevaluasi efektivitas counterweight dalam menurunkan debit rembesan dan meningkatkan stabilitas bendungan. Metode analisis yang digunakan meliputi evaluasi rembesan berdasarkan metode ambang batas, Seepage index, serta pemodelan numerik menggunakan SLOPE/W untuk mengkaji respons hidraulik dan stabilitas lereng setelah pemasangan counterweight. Hasil evaluasi menunjukkan bahwa debit rembesan pada kondisi Elevasi Muka Air Maksimum (+84,00 m) berada jauh di bawah batas yang dipersyaratkan, yaitu 0,0015 liter/menit/meter dibandingkan nilai ambang 0,28 liter/menit/meter. Berdasarkan metode Seepage Index, nilai rembesan sebelum pemasangan counterweight adalah 1,3482 (>1), yang mengindikasikan potensi rembesan berlebih, sedangkan setelah pemasangan nilai turun menjadi 0,3391 (<1), menunjukkan kondisi aman. Hasil pemodelan SLOPE/W menguatkan bahwa perkuatan counterweight memberikan peningkatan signifikan pada stabilitas tubuh bendungan. Secara keseluruhan, penelitian ini menyimpulkan bahwa pemasangan counterweight efektif dalam mengendalikan rembesan, mengurangi risiko uplift, dan meningkatkan tingkat keamanan Bendungan Sadawarna.

Abstract

Landslide in high plasticity stiff overconsolidated clays frequently occur despite high safety factors obtained from analyses based on undrained shear strength. This is because the parameters used in such analyses do not adequately represent slope conditions subjected to repeated deformation and weathering. This study aims to identify the fully softened and residual shear strength parameters, to examine their relationship with the liquid limit (LL) for this soil type, and to find out the suitability of the relationship graph with that developed by Stark & ​​Hussain. Fully softened and residual shear strengths were obtained from direct shear slow reversal test. Remoulded specimens prepared using the slurry method and consolidated under normally consolidated conditions were used. Soil samples were collected from three landslide sites in Semarang. The test results indicate very high LL values (94-105%) with clay fractions exceeding 50% at all sampling locations. Overall, the results show consistency with the  regression bounds relating LL to fully softened and residual friction angles developed by Stark & Hussain. The correlation demonstrates good agreement and is applicable to local clayshales.

Abstract

This study evaluates the outlet system design for the Budong-Budong Dam, with a focus on optimizing downstream water delivery for irrigation purposes, calculated at 410 liters per second. The outlet structures are categorized by their discharge pathways: river outlet channels, channel outlet channels, and pressurized pipe outlets. A bottom outlet is proposed to aid in meeting irrigation demands, with hydraulic analysis conducted to determine the optimal diameter for efficient water flow. Two diameters (0.4 m and 0.6 m) were analyzed for total head loss, factoring in head loss from the trash rack, entrance, and friction. Results show that a 0.4 m diameter produces a head loss of 4.2905 m, while a 0.6 m diameter produces a head loss of 1.8599 m, consistent with Bernoulli’s Principle that smaller cross-sectional areas increase head loss. Both diameters meet the required downstream discharge of 0.705 m³/s, with head loss remaining within safety limits across hollow jet valve openings. The study concludes that both diameters are feasible for downstream discharge requirements, with the installation of the bottom outlet coordinated in parallel with diversion tunnel excavation for project efficiency.

Abstract

The Jlantah Dam is a random fill dam with a vertical core zone. One of the potential hazards of the Jlantah Dam is slope failure caused by the rapid drawdown of the reservoir water level. During a rapid drawdown event, the pore water pressure does not decrease in tandem with the rapid drop in water level. This condition can be a critical factor in slope stability due to the pore water pressure within the dam body. This study aims to analyze the stability of the Jlantah Dam under rapid drawdown conditions using three daily water level reduction scenarios: 2.3 m/day (10 days), 1 m/day (23 days), and 0.75 m/day (31 days). The rapid drawdown is conducted from the normal water level (+685) to the minimum water level (+662), with a total elevation drop of 23 meters. The analysis results show that the percentage reduction in pore water pressure under rapid drawdown conditions is 48.673% for the 2.3 m/day (10 days) scenario, 57.979% for the 1 m/day (23 days) scenario, and 60.309% for the 0.75 m/day (31 days) scenario. The minimum safety factors obtained for each scenario are 1.74023, 1.67292, and 1.6783, respectively. These values remain above the acceptance criteria for stability during rapid drawdown from normal to minimum water levels.

Abstract

The slope stability of the Bagong Dam spillway is controlled by colluvial soils and weathered volcanic rocks containing discontinuities that may form non-circular failure surfaces. This study assesses the existing slope condition and the effectiveness of bore-pile reinforcement using Limit Equilibrium analysis in PLAXIS LE. The lateral capacity of the piles is derived from rock-mass parameters obtained through the RMR–Hoek–Brown correlation and applied as lateral resistance in the numerical model. Independent verification is performed using the Zeng Method (2002) by computing translational equilibrium between slices. The results show that the factor of safety increases from 1.141 (existing) to 1.547 after installing bore piles. The Zeng Method yields FS = 1.5564, confirming strong agreement with the numerical model. The reinforcement enhances lateral resistance and shifts the critical slip surface deeper into more competent rock
