Abstract

Global warming arises due to environmental damage that coincides with one of the causes of building construction projects. Hence, green construction is a solution to minimize the negative impact of development construction projects. This study aims to determine the application of green construction in the Jragung dam, Semarang construction project. Data collection was carried out through a questionnaire survey of respondents from 50 workers from 5 companies (contractors) involved in the construction of the Jragung dam, Semarang. Data analysis was carried out using statistical descriptive analysis methods. The results showed that in the Jragung dam construction project, Semarang, the contractors as the executors and persons in charge of the project had applied the green construction concept even though it has yet to be maximized. The application of green construction based on six assessment indicators has a percentage of 53%-98%. PT Wijaya Karya is a project contractor who has implemented Green construction with the highest percentage of 81%, followed by PT Wijaya Karya.

Abstract

Sungai Waridin, sebagai sungai utama pada DAS Waridin seluas 28,88 km² dengan panjang 8,21 km, sering mengalami banjir akibat kapasitas tampungan yang tidak memadai, topografi curam, pendangkalan sungai, dan longsornya tanggul, terutama saat hujan lebat berdurasi panjang. Analisis debit banjir menggunakan metode Rasional menunjukkan debit rencana 25 tahunan (Q25) mencapai 98,51 m³/detik, yang tidak dapat ditampung dalam kondisi eksisting berdasarkan simulasi HEC-RAS, sehingga beberapa lokasi mengalami luapan air. Untuk mengatasi masalah ini, disarankan perkuatan tanggul menggunakan beronjong berukuran 2 m x 1 m x 0,5 m dan peninggian elevasi tanggul sebesar 0,8 m dari muka air banjir Q25, menghasilkan dimensi tanggul dengan tinggi 3,5 m dan lebar 5,5 m guna menahan debit banjir secara efektif.

Abstract

Irrigation is an effort to drain water from the source to agricultural land to meet the water needs of the land. Irrigated Area (I.A.) East Glapan needs help in the form of channels that carry too much mud or sediment material, thus hindering water distribution to the farthest lands. The lack of optimal mud bag building in the primary channel causes this. Based on these problems, it is necessary to check the effectiveness of the East Glapan I.A. mud bag. The analysis stage involves sediment sample tests and sediment transport calculations using the Shield, Einstein, and Mayer-Patter & Muller (MPM) methods, checking the deposition effectiveness and calculating the draining time. Based on the results of sediment transportation calculations, the highest value of 37.15 tons/day was obtained based on the MPM method. A settling efficiency value of 86.10% was obtained for the effectiveness of sludge bags. Then to optimize the performance of the mud bag, according to the calculation results, it is necessary to drain the mud bag of I.A. East Glapan every four months.

Abstract

Intelligent Transport System (ITS) is an intelligent traffic system used for traffic management and engineering. The ITS network uses inter-vehicle telecommunication technology. The city of Semarang is one of the cities that will establish ITS technology. One area that applies technology is health. The telecommunications system applied in the health sector today allows medical staff to treat patients in ambulances before arriving at the hospital. This communication system needs to be supported by a good cellular network so that data can be sent to the server. This study aims to measure QOS (Quality of Service) including the characteristics of delay, packet loss, jitter, and throughput from various cellular providers. The results of data measurements using wireshark software with TIPHON standard guidelines obtained an average value for delay obtained by Provider A with the best result of 86.22 ms. The average value for packet loss obtained from the measurement results from the Penggaron Terminal to the City Hall Bus Stop was obtained by Provider A with the best result of 0.474% d for the City Hall Bus Stop to the Penggaron Terminal obtained by Provider B with the best result of 0.574%. The average value of jitter obtained from the measurement results from the Penggaron Terminal to the City Hall Bus Stop was obtained by Provider B with the best result of 0.42 ms, for the City Hall Bus Stop to the Penggaron Terminal, Provider A was obtained with the best result of 0.57 ms. The average throughput value obtained from the measurement results for Penggaron Terminal to City Hall Bus Stop was obtained by Provider C with the best result of 6631 Kbps, for City Hall Bus Stop to Penggaron Terminal obtained by Provider B with the best result of 6339.5 Kbps. Based on this, knowing the value of delay, packet loss, jitter and throughput is expected to be a consideration for the development of a smart ambulance system in the city of Semarang. There are two measurement points, namely the Penggaron Terminal to the City Hall Bus Stop and the City Hall Bus Stop to the Penggaron Terminal using the Semarang BRT.

Abstract

Abstrak   Beton geopolimer merupakan beton tanpa semen sebagai bahan pengikat, dipandang sebagai solusi mengatasi pemanasan global akibat produksi semen portland dan alternatif pengganti beton konvensional. Beton geopolimer segar memiliki kekentalan kaku yang tidak workable, padahal workability sangat dibutuhkan dalam proses pengecoran di lapangan. Untuk mengatasi masalah ini, dikembangkan inovasi Self Compacting Concrete (SCC) yang dapat memadat sendiri tanpa alat pemadat. Beberapa metode untuk mendapatkan sifat self compacting meliputi pengaturan kadar agregat, rasio air, dan penggunaan superplasticizer. Penambahan superplasticizer membuat geopolimer lebih workable dengan setting time lebih lama. Pengujian menggunakan slump flow, v funnel, dan box test. Penelitian ini menganalisis kinerja Self Compacting Geopolymer Concrete (SCGC) menggunakan fly ash PLTU Tanjungjati B sebagai pengganti semen. Hasil pengujian menunjukkan campuran berhasil diformulasikan sebagai SCGC berperforma tinggi dengan keseimbangan sangat baik antara fluiditas, stabilitas, dan kemampuan melewati celah sempit. Beton ini efektif untuk aplikasi pada elemen struktur dengan geometri rumit dan penulangan padat, berpotensi meningkatkan efisiensi konstruksi, mengurangi pemadatan mekanis, dan menjamin kepadatan optimal di seluruh struktur.   Kata kunci: SCGC, Fly ash, Slump Flow, V Funnel, Box test   Abstract   Geopolymer concrete is concrete without cement as a binding material, seen as a solution to global warming caused by Portland cement production and an alternative to conventional concrete. Fresh geopolymer concrete has a stiff consistency that is not workable, even though workability is very much needed in the casting process in the field. To overcome this problem, Self Compacting Concrete (SCC) innovation has been developed, which can compact itself without compaction tools. Several methods to obtain self-compacting properties include adjusting the aggregate content, water ratio, and the use of superplasticizers. The addition of superplasticizers makes geopolymers more workable with a longer setting time. Testing was carried out using slump flow, V-funnel, and box tests. This study analyzes the performance of Self-Compacting Geopolymer Concrete (SCGC) using fly ash from the Tanjungjati B power plant as a cement substitute. The test results show that the mixture was successfully formulated as high-performance SCGC with an excellent balance between fluidity, stability, and the ability to pass through narrow gaps. This concrete is effective for applications in structural elements with complex geometries and dense reinforcement, potentially increasing construction efficiency, reducing mechanical compaction, and ensuring optimal density throughout the structure.   Keywords: SCGC, Slump Flow, V-Funnel, Box Test
