Abstract

Konstruksi berbasis kayu mengalami perkembangan pesat dengan munculnya Cross Laminated Timber (CLT), material inovatif yang menawarkan kekuatan tinggi, stabilitas dimensi, dan keberlanjutan. Salah satu aspek penting dalam penerapan CLT adalah desain sambungan dinding tegak lurus. Penelitian bertujuan menganalisis kapasitas geser dan modulus keruntuhan sambungan CLT yang menggunakan sekrup dengan jenis yang berbeda, yaitu tapping screw dan lag screw dengan diameter 5 mm.  Sambungan ini dipasang dengan menghubungkan 3 panel CLT secara tegak lurus dan diperkuat dengan pelat siku. Sambungan CLT lag screw memiliki kapasitas geser maksimum yang lebih besar dibandingkan sambungan CLT tapping screw dengan rata-rata 31,77 kN, dan sambungan CLT tapping screw 28,02 kN. Rata-rata deformasi terbesar pada sambungan CLT tapping screw sebesar 23,49 mm dan lag screw 21,07 mm.  Pelat siku memiliki kapasitas tarik sebesar 560 MPa. Modulus keruntuhan diambil dari nilai terkecil yaitu pada mode kelelehan IIIm sebesar 0,0989 kN. Rasio perbandingan kapasitas geser eksperimental dengan kapasitas geser estimasi untuk sambungan CLT tapping screw sebesar 17,7 dan lag screw 20,07.

Abstract

The community living in Kesiman Kertalangu Village, East Denpasar, Denpasar City, Bali, has a few open shallow wells at home. Well water is used for daily activities such as washing, washing vehicles, and watering plants. The main source of water is groundwater, which is found in rocks below the earth's surface. The availability and movement of groundwater depends on the geological conditions of the area. Groundwater that is used as a source of community life must meet good water quality, so the purpose of this study was to determine the condition of groundwater during the study. The samples used for groundwater testing were 30 wells spread across this village. The methods used were interviews with the local community, field testing of well water samples (smell and temperature tests), laboratory tests (pH, TSS, TDS, DHL and microbiology) and modeling analysis of all research data results using the ARCGIS application. The research results obtained were field tests such as odor tests and temperature tests that passed the clean water requirements because they met the standards set by the Ministry of Health. laboratory tests such as the TDS, TSS and DHL tests have met the requirements as clean water because the number of solid particles dissolved in water and gas is below the specified limits, and the amount of suspended solids in water is also below the limits. Microbiological test results showed that several points were quite polluted by E.Coli and Total Coliform bacteria caused by the distance between the well points and the septic tank in people's homes.

Abstract

Rainfall plays a critical role in the hydrological cycle, affecting various sectors such as water resource management, agriculture, and disaster mitigation. The Global Precipitation Measurement (GPM) satellite is a significant innovation in global rainfall measurement. The availability of GPM satellite data is particularly beneficial for regions with limited ground-based rainfall station data. This study validates rainfall data from the Global Precipitation Measurement (GPM) satellite against ground observation data to calculate dependable flow in Pepe River, Surakarta, using the National Rural Electric Cooperative Association (NRECA) method. The analysis spans data from 2004 to 2024. Validation results show a strong correlation (R = 0,7315) but notable deviations with Root Mean Square Error (RMSE) = 0,415 and NSE = 0,667. Post-calibration (coefficient 0,856), the correlation improves significantly (R = 1, RMSE = 0,016, NSE = 0,758). Dependable flow analysis identifies February as the month with the highest average discharge (1,163 m3/s) and highlights 2017 as the year with a Q80% value of 4,578 m3/s using the Weibull Basic Month method. Comparison of Q80% results with field discharge data, obtained through rating curve conversion, shows that the Q80% value falls within the standard deviation range of field discharge, validating the calculated results. The results of this study are expected to provide insights into the quality of GPM satellite rainfall data for dependable flow estimation.

Abstract

Beton konvensional memiliki dampak yang signifikan terhadap jejak karbon yang diakibatkan karena proses produksinya, terutama pembuatan bahan utamanya, yaitu semen. Oleh karena itu diperlukan segera upaya untuk mencari material lain sebagai pengganti semen dalam pembuatan beton. Salah satu pengganti semen dalam pembuatan beton adalah dengan beton geopolimer. Beton geopolimer merupakan beton yang memiliki reaksi berbeda dengan beton konvensional yaitu reaksi polimerisasi. Beton ini menggunakan limbah dari hasil pembakaran batu bara berupa fly ash yang membutuhkan aktivator untuk mengikat campuran fly ash dengan pasir dan kerikil. Penelitian ini akan meninjau pengaruh kadar aktivator dan variasi rasio SS/SH terhadap kuat tekan beton pada umur 28 hari. Bahan kimia yang digunakan untuk mengaktifkan reaksi polimerisasi pada fly ash adalah dengan menggunakan alkali hidroksida dan alkali silika atau dengan sodium silikat (SS) dan sodium hidroksida (SH). Metode yang digunakan pada penelitian ini adalah metode eksperimen yang dilakukan di laboratorium dengan benda uji silinder tinggi 30 cm dan diameter 15 cm dengan menggunakan kadar aktivator 0,33 untuk perbandingan alkali dengan fly ash dan variasi SS/SH sebesar 0,5 ; 1,0 ; dan 1,5. Berdasarkan hasil eksperimen didapat kuat tekan maksimum sebesar 41,16 MPa pada rasio SS/SH 1,5.

Abstract

Tanah pasir lepas memiliki daya dukung rendah akibat porositas tinggi dan ikatan antarbutir yang lemah. Kondisi ini menjadi tantangan signifikan dalam perencanaan konstruksi fondasi dangkal, karena berisiko menyebabkan penurunan berlebih dan ketidakstabilan struktur. Penelitian ini bertujuan mengevaluasi efektivitas metode Enzyme-Induced Carbonate Precipitation (EICP) berbasis ekstrak kedelai dalam meningkatkan kapasitas daya dukung tanah tersebut. Perlakuan dilakukan satu kali dengan menyuntikkan 9 liter larutan EICP ke dalam media pasir menggunakan metode two-phase. Rasio larutan urease (dari ekstraksi bubuk kedelai) dan sementasi (1 mol/L urea dan 1 mol/L CaCl₂) adalah 1:1, dengan konsentrasi total 22,24% terhadap berat kering pasir. Pengujian meliputi uji beban statik aksial (ASTM D1194) dan uji geser langsung (ASTM D3080). Hasil menunjukkan bahwa kapasitas daya dukung ultimit meningkat sebesar 272,7% (uji aksial) dan 368,2% (perhitungan). Peningkatan sifat tanah juga terlihat dari nilai kohesi hingga 13,78 kPa, sudut geser dalam mencapai 57,16°, dan berat volume tanah naik dari 13,48 menjadi 18,00 kN/m³. Uji ANOVA (F(1,114) = 239,97; p < 0,001) mengonfirmasi pengaruh perlakuan yang signifikan secara statistik. Disimpulkan bahwa metode EICP berbasis kedelai efektif dalam memperbaiki sifat fisik dan mekanik tanah pasir lepas, serta meningkatkan daya dukung fondasi telapak lingkaran secara signifikan.

Abstract

The COVID-19 pandemic, which spread to all countries worldwide, also influenced changes in individual behaviors related to activities and travel. These changes were further intensified by government policies to implement lockdowns to reduce the spread of the Coronavirus. The impact of these policies resulted in a significant decrease in the frequency of public travel, resulting in the preference for the use of private vehicles to avoid Coronavirus transmission. This study was conducted to investigate individual travel behavior in the Surakarta Agglomeration Area. Data were collected through home interview surveys from March to June 2021, involving 402 respondents. It was hypothesized that with regard to sociodemographic attributes, those with high-income levels would rely more on private vehicles during the COVID-19 pandemic, while lower-income groups would show the opposite trend. The results of the study indicated that high-income individuals were highly dependent on private vehicles, particularly cars, compared to those with other attributes. 17.8% of high-income respondents used cars more frequently than those in other income groups, finding them not only safer from COVID-19 transmission but also more comfortable.

Abstract

Urbanisasi yang masif di Kota Surakarta telah mendorong peningkatan area terbangun dan alih fungsi lahan di Daerah Aliran Sungai (DAS) Kali Boro, memicu eskalasi masalah genangan akibat sistem drainase eksisting yang inadekuat. Meskipun banyak studi drainase perkotaan modern mengadopsi model numerik canggih dan solusi berbasis alam, studi ini secara strategis memilih pendekatan hidrologi-hidraulika klasik (Log Pearson Tipe III, Mononobe, Rasional, Manning) untuk mengatasi keterbatasan data spesifik dan sumber daya di tingkat mikro perkotaan tropis, sekaligus menawarkan solusi yang relevan dan aplikatif bagi Pemerintah Kota Surakarta. Pendekatan ini mengisi kekosongan literatur terkait implementasi master plan drainase mikro komprehensif di kota tropis yang masih mengandalkan data primer dan metode yang terjangkau. Penelitian ini bertujuan untuk menganalisis kondisi drainase mikro eksisting, menghitung debit banjir rencana (T = 2, 5, 10 tahun), mengidentifikasi akar permasalahan, dan menyusun master plan drainase mikro di DAS Kali Boro. Hasil analisis menunjukkan bahwa kapasitas saluran drainase eksisting hanya mampu menampung sekitar 72,5% dari debit banjir rencana untuk kala ulang 5 tahun, diperparah oleh penyempitan, sedimentasi, dan penumpukan sampah. Implementasi master plan yang diusulkan, meliputi normalisasi, peningkatan dimensi saluran, perbaikan gorong-gorong, pengelolaan sedimen dan sampah, pembangunan sumur resapan, serta adopsi drainase berwawasan lingkungan, diproyeksikan mampu mengurangi luasan genangan hingga lebih dari 50% di area prioritas. Studi ini menegaskan relevansi pendekatan konvensional yang terjustifikasi dalam konteks lokal, memberikan kontribusi signifikan dalam perencanaan ketahanan banjir di DAS mikro perkotaan tropis, dan dapat menjadi acuan kebijakan adaptasi iklim Kota Surakarta.

Abstract

Concrete has now become the most essential material in modern construction. The strength and durability of concrete are vital factors that influence the strength and stability of buildings and infrastructure. Porosity refers to the degree to which concrete has voids or voids within its structure. Concrete porosity has a significant impact on concrete compressive strength. The higher the level of porosity, the lower the compressive strength of the concrete. In this research, we conducted a concrete formulation experiment by adding a type F additive to MasterGlenium Ace 8595. This research investigates the effect of adding the additive Master Glenium Ace 8595 on changes in concrete porosity and increasing concrete compressive strength. The results of the research show that from the aggregate suitability testing, it was stated that all the aggregates tested were suitable for use as a building material for concrete, workability testing obtained results with dilute criteria, porosity testing obtained an average porosity of 8.05%, and compressive strength testing obtained an average compressive strength value. -an average of 23.56 MPa indicates an increase of 8.69% of the planned concrete quality. This research concludes that concrete porosity is one of the factors that must be considered to increase the compressive strength of concrete because it significantly influences its density and compressive strength. Keeping the porosity at a low level and the compressive strength of the concrete at a high level can ensure that the concrete structure has good resistance to loads and the environment and reduces the risk of damage and maintenance.

Abstract

Engineers increasingly use project management technology such as Building Information Modelling (BIM) to optimize resource utilization and minimize costs in construction projects. Cubicost is a 5D BIM software used for volume and material price calculations. This research aims to compare architectural work volumes using Cubicost Takeoff for Architecture and Structure (TAS) with contractor volumes and conduct a comparison analysis of the Budget Plan (RAB). This study employs a quantitative method through a simple linear regression approach to validate Cubicost results with the author's manual calculations. First, data is collected to be modeled using Cubicost software. Then, a simple linear regression analysis is conducted to assess the validity of Cubicost based on the author's manual calculations. Next, a comparison of volumes and RAB between Cubicost results and contractors is performed to analyze deviations caused by contractor human error factors and determine the percentage of efficiency in Cubicost software usage. The comparison of Cubicost with the contractor results in a cost efficiency of Rp734,925,053.97 or an efficiency percentage of 18.429%. Based on these results, this research recommends the implementation of Cubicost in the construction project of the Integrated Multi-Matra SBSN ISI Surakarta Laboratory Building for decrease human error in this project.
