Abstract

Pontianak adalah ibu kota provinsi Kalimantan Barat dimana berdasarkan peta zonasi gempa berada pada daerah dengan tingkat risiko gempa yang sangat rendah sehingga perencanaan struktur di Pontianak tidak perlu diperhitungkan terhadap beban gempa. Tetapi dalam perkembangannya,  perencanaan struktur pada daerah dengan tingkat risiko gempa yang rendah harus turut diperhitungkan terhadap beban gempa. Seperti pada perencanaan pembangunan Gedung Rektorat Universitas Panca Bhakti Pontianak ini yang beralamat di Jl. Komyos Sudarso No. 1 Kota Pontianak. Perencanaan dimensi-dimensi elemen struktur pada bangunan ini mengacu pada SNI 1726-2012 mengenai perencanaan ketahanan gempa untuk struktur bangunan gedung agar bangunan tersebut mampu menahan beban mati, beban hidup, dan beban gempa rencana yang bekerja dan menghasilkan elemen-elemen struktur yang efisien dan memenuhi persyaratan dan pedoman yang berlaku. Dimensi yang telah ditentukan tersebut selanjutnya dihitung terhadap beban-beban yang bekerja dengan bantuan program analisa struktur ETABS agar dapat diketahui apakah dimensi tersebut efisien dan dapat menahan beban yang bekerja. Kata kunci: Beban gempa; etabs; perencanaan; struktur.

Abstract

The geoelectric method is an effective geophysical method in subsurface mapping by utilizing the electrical properties of rocks. The basic principle of the geoelectric method is to measure resistivity by flowing an electric current into the earth through electrodes. Geoelectrical (resistivity) surveys generally aim to determine the condition or structure of subsurface geology based on variations in rock type resistance. The results of the training showed significant variations in the resistivity of Andesite and Granite rocks, which were indicated as potential resource zones worthy of further exploration. The results of resource potential calculations show that the volume of Andesite is 909,364,491 m³ and the volume of granite is 55,436,878 m³. This training also provides recommendations for residents in Salatiga District, Sambas Regency, to use this as literature to attract investors so they can invest in the area as much as the relevant volume.

Abstract

Pontianak, sebagai Ibu Kota Provinsi Kalimantan Barat, berdasarkan peta zonasi gempa termasuk wilayah dengan tingkat risiko gempa sangat rendah. Meskipun demikian, perkembangan terkini menunjukkan bahwa perencanaan struktur di daerah berisiko gempa rendah tetap perlu mempertimbangkan beban gempa sebagai bagian dari desain yang komprehensif. Penelitian ini mengkaji perencanaan struktur tahan gempa pada bangunan strategis berbasis fungsi akademik, dengan studi kasus pada suatu gedung pendidikan yang berlokasi di kawasan perkotaan. Perencanaan dimensi elemen struktur mengacu pada SNI 1726-2012 tentang ketahanan gempa untuk memastikan kemampuan bangunan dalam menahan kombinasi beban mati, hidup, dan gempa. Analisis dilakukan menggunakan program ETABS untuk mengevaluasi efisiensi dimensi struktur dalam menahan beban yang bekerja. Hasil penelitian menunjukkan bahwa meskipun risiko seismik di Pontianak rendah, penerapan standar gempa tetap menghasilkan elemen struktur yang efisien, memenuhi persyaratan teknis, dan meningkatkan kesiapsiagaan struktural terhadap potensi beban dinamik. Studi ini menegaskan pentingnya integrasi prinsip tahan gempa pada bangunan strategis, bahkan di wilayah dengan zonasi risiko rendah, sebagai langkah antisipatif dalam mitigasi bencana.

Abstract

This study critically analyzes the implementation of constitutional principles within the framework of structural safety regulations for building constructions in Indonesia. The intersection between constitutional law and civil engineering becomes urgent to analyze considering the significant transformation of building construction regulations following the enactment of the Job Creation Law (Law No. 11 of 2020) and Government Regulation No. 16 of 2021. The study employs a normative juridical approach integrated with technical analysis through doctrinal legal research methods while still considering empirical aspects of structural safety standards. Through legislative, conceptual, and comparative approaches, this study identifies significant implementation gaps between constitutional principles and structural safety technical standards. The results indicate that: (1) there is disharmony between constitutional principles and the implementation of technical regulations, especially in the aspect of protecting citizens' human rights; (2) the paradigm shift from Building Permit (IMB) to Building Approval (PBG) has not fully accommodated the fulfillment of constitutional rights of building users; and (3) the state's constitutional accountability mechanism in building failures remains weak. The study recommends reformulating structural safety regulations that integrate constitutional principles with technical standards by strengthening the state's responsibility dimension in ensuring building safety, as well as improving the Building Feasibility Certificate (SLF) mechanism as a constitutional protection instrument. Keywords: Building construction, normative juridical study, job creation law

Abstract

This study examines public transportation accessibility in Bandung, the capital of West Java Province, located at 107 °36' E and 6 °55' S, covering 167.31 square kilometers and characterized by a mountainous "bowl-shaped" topography. Trans Metro Bandung (TMB) operates an integrated network of five main corridors and two feeder routes to enhance urban mobility. Corridor 1, the longest route, spans approximately 20 kilometers from Cibiru Terminal in the east to Cibeureum Terminal in the west, passing through major roads and serving 86 bus stops distributed across educational, commercial, office, and residential areas. The study utilizes secondary spatial data, including Bandung"™s road network and bus stop locations from the Trans Metro Bandung. Administrative boundary data delineates the study area. Using GIS software, the research compares two accessibility measurement methods: the circular buffer, which creates fixed-radius catchment areas around stops, and the service area buffer, which calculates accessible areas based on the actual street network. Both buffer types are merged to remove overlapping areas, producing union buffers representing unique coverage zones. Accessibility indices are calculated based on the union buffers: the Ideal Stop-Accessibility Index (ISAI) measures the ratio of circular buffer coverage to the ideal corridor buffer; the Actual Stop-Accessibility Index (ASAI) measures the ratio of service area buffer coverage to the ideal; and the Stop Coverage Ratio Index (SCRI) compares service area coverage to circular buffer coverage. These indices prevent overestimation caused by overlapping buffers and provide a realistic assessment of transit stop accessibility. This study provides valuable insights for developing more accurate and sustainable public transportation strategies in Bandung and similar urban contexts.

Abstract

Geopolymer concrete is a form of concrete where Portland cement is substituted with alternative materials like fly ash, rice husk ash, and other silica- and aluminum-rich sources as binders. The research employed an experimental method by preparing geopolymer concrete test specimens using fly ash, NaOH solution, Naâ‚‚SiO₃, fine aggregate, and coarse aggregate. Tests conducted included physical properties (slump test and unit weight) and mechanical properties (compressive strength, split tensile strength, and modulus of elasticity). The results showed a slump range of 130"“190 mm, an average unit weight between 2249.39 kg/m ³ and 2336.39 kg/m ³, a 28-day average compressive strength between 12.32 MPa and 15.92 MPa, an average split tensile strength between 1.46 MPa and 1.56 MPa, and an average modulus of elasticity (Chord Modulus) between 3011.67 MPa and 3881.8 MPa. The optimal variation was achieved with an NaOH solution concentration of 10 M, resulting in a slump of 160 mm, a 28-day average compressive strength of 15.92 MPa, an average split tensile strength of 1.56 MPa, and an average modulus of elasticity (Chord Modulus) of 3881.48 MPa. Therefore, fly ash-based geopolymer concrete demonstrates potential as a viable substitute for cement as a binder material.

Abstract

Geopolymer concrete is a sustainable alternative that replaces Portland Cement (PC) with fly ash. This research aims to analyze the mechanical properties of geopolymer concrete with variations in NaOH solution aging. An experimental method was applied through a series of tests, including slump, compressive strength, split tensile strength, and modulus of elasticity. The results indicate that the slump value ranges from 9,5 cm to 15,5 cm. The bulk density of geopolymer concrete varies between 2.313,052 Kg/m ³ and 2.387,324 Kg/m ³. The maximum compressive strength at 28 days was achieved after a 24-hour NaOH curing period, reaching 15,915 MPa, whereas the minimum strength of 10,186 MPa was observed with no curing time. The highest split tensile strength was observed at 24 hours (1,556 MPa), whereas the lowest occurred at 0 hours (1,085 MPa). Using the Chord Modulus method, the modulus of elasticity reached its highest value at 24 hours (3.625,261 MPa) and its lowest at 48 hours (2.152,499 MPa). Thus, this research concludes that a 24-hour NaOH curing period results in geopolymer concrete with optimal compressive strength and mechanical properties.

Abstract

Concrete is a primary construction material composed of a mixture of aggregates, cement, and water, where the proportion of each component significantly influences its physical and mechanical properties. A common issue in conventional concrete production is a reduction in strength due to uncontrolled porosity and poor air distribution. This study aims to evaluate the effect of sand powder substitution on concrete characteristics and to determine the optimal composition that enhances mechanical performance without compromising material efficiency. The experimental tests were conducted at the Materials and Construction Laboratory, Faculty of Civil Engineering, Universitas Tanjungpura, using a sand powder variation of 0%, 5%, and 10%. The tested parameters included unit weight, compressive strength, splitting tensile strength, flexural strength, and elastic modulus at curing ages of 3 to 28 days. The results showed that conventional concrete achieved the highest compressive strength of 34.802 MPa at 28 days, while the mixtures with 5% and 10% sand powder reached 26.26 MPa and 25.917 MPa, respectively. Although the substitution of sand powder reduced mechanical strength, its use has the potential to enhance construction sustainability by reducing the consumption of natural sand and utilising mineral waste as a replacement material.
