Abstract

Slope stability is an important aspect in construction planning, especially in areas with weak soil conditions and high rainfall that have the potential to trigger landslides. This study aims to analyze the effect of variations in pile depth in combination with retaining walls (DPT) on increasing slope stability. The method used is numerical analysis using Plaxis software with a Mohr-Coulomb soil model based on secondary data of geotechnical parameters. The variations in pile depth described include 12 meters, 16 meters, 19 meters, and 20 meters. The results of the analysis show that the existing slope condition has a safety factor (SF) value of 1.270 and decreases to 1.064 after being given additional loads, which indicates unstable conditions. The application of DPT and pile reinforcement can significantly increase the SF value, with values ​​of 1.540 (12 m), 1.124 (16 m), 2.354 (19 m), and 2.450 (20 m), respectively. A depth of 19 meters is determined as the optimal condition because it provides a significant and efficient increase in stability. Thus, variations in pile depth have been shown to significantly impact slope stability and can be used as a reference in designing safe and economical slope reinforcement.

Abstract

This study analyzes the impact of compaction levels and paper pulp ratios on the compressive strength of papercrete blocks. The objective is to develop a lightweight building material that meets structural strength standards based on SNI 03-0348-1989. The base formulation combines cement and sand in a 1:3 ratio, with the sand volume substituted by paper at variations of 80%, 90%, and 100%. Density engineering was conducted by compressing the initial mixture volumes of 120%, 130%, 140%, and 150% into a standard size of 5 cm x 10 cm x 20 cm. Mechanical performance testing involved single blocks, paired blocks bonded with a 1 cm mortar joint, and conventional red bricks as a control comparison. Experimental results demonstrate that most papercrete variants qualify as structural materials within classes II, III, and IV. Only the 120PB100 sample failed to meet the standard classification. Interestingly, the standard red brick did not qualify for any strength class under the SNI framework. The highest mechanical performance was achieved by the 140PB80 variant, yielding a single-block compressive strength of 70.139 kg/cm². However, when evaluated in a paired formation, the strength of this 140PB80 sample reduced by 29.87% to 49.190 kg/cm².

Abstract

This study aims to analyze the mineral composition of clay soil and coffee husk ash, as well as to evaluate the effect of coffee husk ash as a stabilizing agent for clay soil. The main problem addressed is the high plasticity of clay soil, which causes volume changes and reduces bearing capacity, making stabilization methods necessary. The research was conducted by collecting clay soil samples from Kebun Kurma Barbate, Aceh Besar, and coffee husk ash from Aceh Tengah. Mineral composition was analyzed using gravimetric, titrimetric, spectrophotometric, and AAS methods, while soil plasticity was examined through Atterberg limits and specific gravity tests. The results indicate that clay soil contains dominant Silica Oxide (SiO₂) at 42.99% and Aluminum Oxide (Al₂O₃) at 5.63%, contributing to its high plasticity. Meanwhile, coffee husk ash contains 8.30% SiO₂ and 5.22% Calcium Oxide (CaO), which play crucial roles in stabilization. The addition of 5– 25% coffee husk ash reduced the plasticity index from 38.42% to 34.29%, increased soil specific gravity from 2.587 g/cm³ to 2.690 g/cm³, and transformed soil classification from clay to silt. These findings confirm the potential of coffee husk ash as an effective, and sustainable stabilizing material for geotechnical engineering applications

Abstract

Langsa City, Aceh, is an area prone to both flooding and earthquakes. Recurrent flooding can deteriorate building conditions, including foundation damage, wall cracking, material degradation, and reduced structural performance, which may increase vulnerability to future earthquake events. This study aims to assess the vulnerability of the construction sector following flood disasters as a basis for developing earthquake risk reduction strategies in Langsa City. A descriptive qualitative approach was employed using field observations and in-depth interviews. The collected data were analyzed through thematic analysis based on three dimensions: technical, socio-cultural, and political-economic aspects. The findings reveal that construction sector vulnerability in Langsa City is multidimensional. From the technical aspect, vulnerability is associated with material deterioration, wall cracks, and inadequate drainage systems. From the socio-cultural aspect, limited public awareness of earthquake-resistant construction practices and reliance on traditional building experience contribute to increased vulnerability. From the political-economic aspect, financial constraints, unequal distribution of rehabilitation assistance, and weak construction oversight further exacerbate risks. The study concludes that reducing earthquake vulnerability in post-flood areas requires integrated efforts, including structural strengthening, drainage improvement, community education on disaster-resilient construction, and the incorporation of flood and earthquake risk considerations into local development policies.

Abstract

Dalam proyek konstruksi kontraktor dihadapkan pada berbagai risiko biaya, berbagai usaha dilakukan untuk dapat menghindari atau mengurangi risiko sehingga dapat dicapai hasil yang efektif. Salah satunya adalah dengan menganalisa risiko dari kontrak proyek konstruksi diantaranya kontrak yang sering digunakan yaitu kontrak Lumpsum dan kontrak Unit Price. Tujuan dari penelitian ini adalah mengetahui alternatif pemilihan antara kontrak Lumpsum dan Unit Price pada proyek konstruksi di Kota Banda Aceh.  Penelitian ini dilakukan dengan menyebarkan kuesioner kepada perusahaan yang pernah mengerjakan proyek konstruksi di Kota Banda Aceh. Pemilihan alternatif kontrak dengan metode Analytical Hierarchy Process (AHP) dengan jumlah responden pada penelitian ini adalah 10 responden. Teknik sampling yang digunakan adalah Purposive Sampling. Penelitian ini terdiri dari kriteria dan subkriteria mengenai risiko yang mungkin terjadi di proyek konstruksi. Berdasarkan hasil penelitian menggunakan metode AHP maka diperoleh pemilihan alternatif utama pada risiko yang mungkin terjadi pada proyek konstruksi di Kota Banda Aceh adalah pada subkriteria biaya kontrak Unit Price memiliki bobot risiko 0,0000001 (0,00001%), dibandingkan dengan kontrak memiliki bobot risiko 0,9999999 (99,99999%). Sedangkan pada subkriteria waktu dimana kontrak Lumpsum memiliki bobot risiko 0,00005 (0,005%), dibandingkan dengan kontrak Unit Price memiliki bobot risiko 0,99995 (99,995%). Sedangkan pada subktiteria mutu kontrak Unit Price memiliki bobot risiko 0,0001 (0,01%), dibandingkan dengan kontrak Lumpsum memiliki bobot risiko 0,9999 (99,99%). Pada pembobotan alternatif secara keseluruhan kontrak Unit Price dengan bobot risiko 0,3333 (33,33%), dibandingkan dengan kontrak Lumpsum memiliki bobot risiko 0,6667 (66,67%).
