Abstract

Climate change and geographic location affect water availability. Coastal areas in Indonesia generally have drinking water problems because the well water is dry due to the dry season and the water is brackish, as is the case in Sawojajar Village in Brebes Regency, Central Java. On the other hand, the potential for rainwater in Sawojajar Village is quite good. The Brebes Regency Government is planning and implementing a rain harvesting (Gama Rain Filter) with an individual type for people who want to install rainwater harvestings in their homes, and a communal type for people who still want communal rainwater harvestings. This applied research aims to compare the two types. The individual type planning method for harvesting rain is carried out in each house and the communal type planning method is carried out in groups of houses. The planning carried out includes checking the quality and quantity of rainwater, calculating the dimensions of the storage tank, design drawings, and planning and implementation budget plans. The results of this applied research are the quality and quantity of rainwater, the design of individual and communal type rainwater harvestings, and the planning costs and implementation costs required. This research resulted in the conclusion that the individual type rain harvesting is more recommended than the communal type because the individual type costs less to plan and construct, is more flexible in placement, easier to manufacture, and maintains operations more securely.

Abstract

The Aesesa watershed is the largest watershed in the Flores River Basin located in Ngada Regency and Nagekeo Regency, with a watershed area of 1,169.24 km2 and a main river length of 66.92 km. The Aesesa watershed consists of 13 sub-watersheds with varying shapes and complex characteristics. This makes the Aesesa watershed potentially prone to flooding. The purpose of this study is to identify the potential for flooding from sub-watersheds in the Aesesa watershed using the Cendana method. The data used include morphometry data, watersheds, and maps. In using the Cendana method, the input parameters taken into account are watershed area (A), main river length (L), annual maximum daily rainfall, watershed shape, river density (D), river slope (s), Nakayasu α value, channel roughness (n), curve number value (CN), and land cover. Then from the calculation of the data, value weighting will be carried out to identify flood vulnerability. The results of this study show that the weighting for 13 sub-watersheds in the Aesesa watershed is on average in the high category with a range value of 2.30 – 2.70. From this result, it is expected that mitigation and adjustment efforts can be made, especially in sub-watersheds that are already high with a weight value of 2.70 to reduce the magnitude of losses due to flooding.

Abstract

Infrastructure development is crucial to the development of a nation’s economy. Based on data from the 2021 World Competitiveness Yearbook, Indonesia's infrastructure is ranked 57th out of 64 countries and one of the assessment criteria is related to water resources. Water resource management in Indonesia is still faced with fundamental challenges, including the limited water storage capacity in Indonesia so alternative water resources development is needed, among which is through the construction of dams. In practice, dam projects are very vulnerable to time delays. One of the solutions to this problem is the application of the last planner system method. The implementation of the last planner system can help create major improvements in project planning, increase workflow and productivity, and reduce project time and site accidents. This research has an update regarding the implementation of the last planner system method on a dam project and analyzing the key success factors using SEM-PLS. According to the study's findings, the key success factors of the implementation of the last planner system method on dam projects are budget plan, work schedule, clarity of scope of work, work plan, planning process, and weekly plan

Abstract

Rainfall stations around the Meninting Dam catchment area are very limited. Global Precipitation Measurement (GPM) satellite rainfall data can be utilized to fulfill the lack of rainfall data. This research aims to improve the quality of flood discharge in the Meninting Dam catchment area through rainfall data correction. GPM rainfall data was corrected using the probability curve method, while flood discharge analysis used HEC-HMS modeling. The results showed that the correlation coefficient of GPM rainfall data with Sesaot Rainfall Station was 0,73, the average HHMT error decreased by 2.99% after correction, and the correction factor level was 0-1,2 for each rainfall value range. The flood discharge (Q) of HEC-HMS modeling for each return period was obtained Q2th = 117,1 m3/sec, Q5th = 142,5 m3/sec, Q25th = 242,3 m3/sec, Q100th = 335,6 m3/sec, Q1000th = 529,3 m3/sec, and QPMF = 930,9 m3/sec.

Abstract

Imogiri - Dlingo road section is a primary collector road located in the Mangunan tourist area, Bantul, Indonesia. This road is a provincial road with hilly terrain, lots of sharp turns, and long ascents and descents, which are potential for traffic accidents. Police data records that in February 2022 there was an accident on this road with 13 deaths and 33 injuries. Therefore, this study aims to evaluate road geometric, both horizontal and vertical alignments on Imogiri - Dlingo road based on Guidelines for Road Geometric Design number 13/P/BM /2021. To do so, road geometric analysis is conducted by employing road safety inspection data, which is then modeled using AutoCAD Civil 3D software. Based on the survey on road geometric, it is known that the number and width of lanes and shoulders are in accordance with Guidelines. Meanwhile, the analysis results using computer program show that this road has 24 horizontal and 6 vertical alignments. Nevertheless, 87% of bend radius, 67% of curve length, 58% of bend angle, 43% of slope, 57% of critical length, and 67% of control design (K) are not fulfilled the requirements. Therefore, Imogiri - Dlingo road is dangerous road and is potentially causing fatal accidents.

Abstract

Penguatan serat ijuk pada campuran beton aspal digunakan untuk meningkatkan kekuatan dan indeks kelelehan akibat peningkatan beban lalu lintas dan pengaruh temperatur guna mengurangi potensi terjadinya deformasi permanen. Tujuan dari penelitian ini adalah untuk menilai sejauh mana pengaruh serat ijuk sebagai bahan penguat dalam meningkatkan kekuatan kohesif dan tarik dari campuran beton aspal, terutama dalam merespons perubahan temperatur. Penelitian ini dilaksanakan menggunakan metode eksperimental di laboratorium dengan menggunakan serat ijuk berdasarkan persentase optimum sebesar 0,6%, memiliki panjang 8 mm, dan diuji dengan variasi temperatur. Hasil pengujian menunjukkan bahwa campuran beton aspal yang diperkuat dengan serat ijuk (DP) memiliki total deformasi sebesar 1,09 mm pada suhu pengujian 40°C. Laju deformasinya sebesar 0,0033 mm/menit, yang lebih kecil dibandingkan dengan campuran beton aspal tanpa serat ijuk (TS) yang memiliki total deformasi 1,19 mm dan laju deformasi 0,0040 mm/menit pada suhu yang sama. Pada suhu 60°C, campuran beton aspal dengan serat ijuk (DP) menunjukkan total deformasi sebesar 1,83 mm dengan laju deformasi 0,0107 mm/menit, sementara tanpa serat ijuk memiliki total deformasi sebesar 2,00 mm dengan laju deformasi 0,0113 mm/menit. Pada hasil pengujian kuat tarik tidak langsung campuran beton aspal tanpa menggunakan serat ijuk mudulus kekakuan campuran lebih rendah dibandingkan dengan menggunakan serat ijuk dan mengalami penurunan secara linier seiring dengan meningkatnya temperatur.

Abstract

The Sumedang-Cirebon Km 68+750 road section is a national road and an important transportation infrastructure in West Java. Albeit the road section's slope has previously been strengthened with bored pile reinforcement, the slope continues to move. This study's objective is to examine slope stability by considering earthquake loads and to suggest improvements for efficient slope reinforcement. Slope stability analysis utilizing PLAXIS 2D program based on the finite element method and DMT-KD Method which is the result of field testing using the Flat Dilatometer Test (DMT)). PLAXIS modeling results show that the slope failure line is deeper below the bored pile reinforcement. The results of the analysis using DMT-KD method showed similar slope failure, the conclusion is DMT-KD method can be the initial basis for slope stability analysis on mudstone. The PLAXIS modeling results obtained a static safety factor of 1.113 and a safety factor due to an earthquake of <1, both of which fall short of the requirements of minimum of 1.5 for static loads and 1.4 for earthquake loads. The body of the road develops cracked as a result of this issue. Additional reinforcement modeling is carried out using bored piles and gabions. As shown in the results of additional reinforcement modeling, bored pile reinforcement that reaches below the slope failure line is more successful than gabion reinforcement at the slope's base in raising the safety factor.

Abstract

A thermal energy foundation is an innovative combination of a foundation structure with thermal pipes that can absorb geothermal heat. This allows it to serve as an alternative source of electricity for the building above it. The goal of this technology is to help achieve sustainable infrastructure targets by minimizing the use of fossil fuels from a geotechnical perspective. This study aims to analyze the thermal effect on foundation deformation using the Finite Element Method approach. The modelling is done using PLAXIS software with element meshes to provide comprehensive deformation results. Additionally, the model is used to vary the thermal parameters of the soil and the quality of the foundation concrete. The analysis results indicate that variations in thermal conductivity values lead to a 34.112% decrease in deformation due to reduced thermal conductivity, while variations in the quality of concrete used in the foundation show a relatively small or insignificant effect on the deformation.

Abstract

Kabupaten Demak dan Grobogan merupakan wilayah yang sering mengalami banjir saat musim penghujan. Salah satu upaya untuk mengatasi banjir pada daerah tersebut, Kementerian PUPR membangun Bendungan Jragung yang direncanakan dengan menggunakan data series Tahun 1998 – 2017. Debit Sungai Jragung cenderung mengalami peningkatan dalam kurun waktu 10 tahun, yang salah satu kemungkinan penyebabnya adalah perubahan tutupan lahan. Maka, untuk mengetahui pengaruh perubahan tutupan lahan terhadap karakteristik hidrograf banjir Waduk Jragung, perlu dilakukan analisis penelusuran banjir di Waduk Jragung. Studi ini menggunakan program HEC-HMS dengan metode Soil Conservation Service (SCS – CN). Indeks perubahan tutupan lahan yang digunakan adalah curve number dan impervious. Hasil analisis menunjukkan adanya perubahan tutupan lahan pada DTA Waduk Jragung sebesar 2,5% yang didominasi oleh peningkatan luasan pemukiman sebesar 55,6%. Akibat dari perubahan tutupan lahan tersebut, debit banjir daerah tangkapan air Waduk Jragung mengalami kenaikan untuk semua kala ulang n-tahun. Besaran QPMF meningkat dari 1586,1 m3/dt menjadi 1689,6 m3/dt yang mengakibatkan peningkatan elevasi muka air banjir waduk dari +118,6 m menjadi +118,7 m.

Abstract

Produktivitas operasi masih menjadi tantangan sektor konstruksi. Keterbatasan ruang dan metode konstruksi turut mempengaruhi hal tersebut. Kondisi ini dialami oleh Universitas Pasundan dalam pembangunan gedung baru. Lokasi yang sempit dan padat mempengaruhi pembangunan gedung tersebut. Untuk itu, penelitian ini melakukan evaluasi produktivitas secara khusus pada operasi pemasangan balok baja berdasarkan data Time Studies, Method Productivity Delay Model (MPDM), Work Sampling dan 5 Minutes Rating. Analisis produktivitas dilakukan dengan menggunakan Method Productivity Delay Model (MPDM), Cycle Chart, Process Chart dan Crew Balance Chart. Hasilnya, evaluasi produktivitas keseluruhan operasi pemasangan balok baja menunjukkan perbandingan presentase pelaksanaan pekerjaan dibanding delay sebesar 62% berbanding 38%. Hasil ini cukup baik mengingat jangkauan proporsi produktivitas pekerja konstruksi berada pada rentang 40-70% dibandingkan dengan 62% pada proyek ini. Peningkatan produktivitas masih dapat dilakukan dengan mencegah delay akibat peralatan; efisiensi jumlah pekerja khususnya peladen; serta optimalisasi durasi masing-masing tugas dengan mengacu pada durasi terbaik yang diperoleh dari hasil pengamatan. Dengan demikian, nilai produktivitas pemasangan tiap batang balok baja dapat meningkat dari 10,36 menit/unit menjadi 6,25 menit/unit. Hasil ini diharapkan dapat menarik penelitian-penelitian serupa dengan objek perhitungan produktivitas yang berbeda untuk menghasilkan data produktivitas operasi konstruksi di Indonesia dan mendorong peningkatan produktivitas di sektor konstruksi.
