Abstrak Pelayanan kebutuhan air di wilayah IKK Bukit Oregon kurang memadai diduga jaringan pipa menjadi pokok masalahnya sehingga berdasar hal tersebut maka diperlukan evaluasi jaringan perpipaan air minum dan design dibuat dengan menggunakan software Aplikasi Watercad V8-I dan ingin diketahui seberapa besar kebutuhan debit pada proyeksi tahun 2030 termasuk kapasitas pompa dan jenis pipa transmisinya. Hasil pengamatan secara langsung di wilayah studi pada pelayanan terdapat permasalahan yang terjadi pada pipa transmisi, yaitu pipa dari intake (sumber air baku utama) menuju ke Instalasi Pengolahan Air (IPA) yang akan di distribusikan ke masyarakat. Permasalahan yang terjadi adalah pipa induk tersebut mengalami kebocoran akibat umur teknis pipa yang sudah tua. Meningkatnya jumlah penduduk sama halnya semakin meningkatnya pemenuhan akan kebutuhan air bersih. Permasalahan tersebut harus ditanggulangi dengan pergantian pipa dengan jenis dan diameter yang tepat serta kapasitas pompa yang sesuai hasil menggunakan software Watercad V8-i. Dari hasil perhitungan analisa pertumbuhan penduduk pada tahun 2030 dengan jumlah pelanggan 96.770 jiwa kebutuhan air mencapai 102,476 liter/detik. Sistem transmisi menggunakan sistem pompa dengan kapasitas terpasang 90 liter/detik. Jenis pipa yang dipakai untuk pipa transmisi menggunakan pipa HDPE dengan diameter 350 mm. Kata kunci: evaluasi, air bersih, perpipaan, pompa, Watercad V8-i Abstract The service for water needs in the IKK Bukit Oregon area is inadequate, it is suspected that the pipeline network is the main problem, so based on this, it is necessary to evaluate the drinking water piping network and the design is made using the Watercad V8-I application software and wants to know how much the demand for discharge in the 2030 projection includes pump capacity and type of transmission pipe. The results of direct observations in the study area on the service there are problems that occur in the transmission pipe, namely the pipe from the intake (main raw water source) to the Water Treatment Plant (IPA) which will be distributed to the community. The problem that occurs is that the main pipe has a leak due to the technical age of the pipe which is old. The increasing population is the same as the increasing fulfillment of clean water needs. These problems must be overcome by changing the pipe with the right type and diameter and the pump capacity according to the results using the Watercad V8-i software. From the calculation results of population growth analysis in 2030 with the number of customers 96,770 people, water needs reach 102,476 liters/second. The transmission system uses a pump system with an installed capacity of 90 liters/second. The type of pipe used for the transmission pipe uses HDPE pipe with a diameter of 350 mm. Keywords: evaluation, clean water, piping, pump, Watercad V8-i

Bridges are a critical part of transport infrastructure networks for social activities and economics of human life. Dynamic analysis of bridge is very important to perform in order to ensure the ability of the bridge to withstand loads and maintain the sustainability of transport infrastructure. This paper presents a methodological framework for monitoring dynamic behavior of the bridge (e.g., natural frequencies, displacement time history) by using civil engineering micro-tremor technique and numerical modeling. The study was conducted at the Alue Raya Bridge located in Lhokseumawe City, Aceh Province, Indonesia. To capture the dynamic behavior of the bridge under traffic loading, the micro-tremor techniques, e.g., Short Period Seismograph (SPS) sensor was placed underneath the bridge at the mid span of the bridge girder. The obtained vibration data were processed using Geopsy software. A three dimensional (3D) model of the bridge was then developed by using CSI Bridge software. The modal analysis was conducted to obtain the modal natural frequencies of the bridge due to traffic loads. The natural frequency measurements using SPS were compared with the simulation results. Through analyzing the measured results, it was found that the natural frequency of the bridge is around 4,3275 Hz which is very close to those obtained from numerical modeling using CSI bridge software. The measured maximum vertical displacement of the bridge girders is below 5mm under normal traffic condition which is under the allowable serviceability limit state requirements of the bridge. The outcomes of this study could have the potential to enable maintenance and capital works decisions which are an important component of the sustainability of transport infrastructure.

One of the approaches to producing lightweight concrete is by adding the aluminum powder to the cement mixture to create air bubbles in the concrete as such enabling pores to appear in the concrete. Aluminum powder can reduce the weight of lightweight concrete despite its tendency to reduce compressive strength. The compressive strength of concrete can be increased by certain methods, one of which is by the addition of Plastiment-VZ admixture. This study aims to investigate the effect of the use of Plastiment-VZ admixture on the compressive strength and flexural strength of lightweight concrete. The normal concrete compressive strength is designed to the range of 0.7 MPa – 5.0 MPa. The concrete testing specimens were in the form of a cube of 15 cm x 15 cm x 15 cm for the compressive test and beams with dimensions of 15 cm x 15 cm x 60 cm for the flexural test. The test results of the compressive strength obtained for normally aerated concrete (0% of Plastiment-VZ) is 6.31 MPa; and for the variation of 0.2% is 6.52 MPa, for 0.4% is 6.8 MPa, and for 0.6% is 8.04 MPa. The highest increase in strength occurred at 0.6% variation, which is 27.46% above normally aerated concrete. The degrees of flexural strength of the concrete produced from each variation of 0%; Based on the findings, it can be concluded that Plastiment-VZ has a significant effect on increasing the compressive strength and flexural strength of lightweight concrete. The more quantity of Plastiment-VZ is used, the higher the compressive strength and flexural strength are produced; even though, the optimum level for the use of Plastiment-VZ for aerated concrete has not been found.

Micro Hydro Power Plant (PLTMH) is a small-scale power plant with an installed capacity of under 200 kW that uses water flow from irrigation channels, rivers, or natural waterfalls by utilizing potential waterfalls at the proposed site. This study discusses the planning and equipment needed for the PLTMH located in a rural area such as Tingkem Village to meet the electricity needs of local residents. The research also includes the technical feasibility study aspect by surveying the hydrological potential and the height of the waterfall at the proposed site. Based on the study, the electricity needs of the residents of Tingkem Village at a peak load of 20kW. The results of the survey show that the potential of water discharge in the Aih Tilis river in Tingkem Village is about 0.95 m3/s with a flow discharge designed of 0.38 m3/s and has a head of about 7.5 m so that it can generate a power of 28 kW which is sufficient to meet the needs of local residents. Based on the head, discharge plan and installed capacity, the appropriate turbine type is a cross-flow type and the generator type is the synchronous generator type. Based on the findings, it can be said that the PLTMH is suitable to be developed in the Tingkem Village.

The small hydropower plant with a run-of-river concept are being increasingly adopted in less developed and developed countries. The optimization of the plant capacity is critical in the successful development of the plant. The adoption of the current technology will assist in the optimization of the plant development. The important criteria in the evaluation of the optimization are the energy output and plant factor of the plant. In this study, twelve scenarios by varying the installed capacity in range of 4MW to 7.5MW has been simulated in order to obtain the most optimum installed capacity of the plant. In respect to the installed capacity, by the adopting the same available net head of 246.75 m, the design flow would be in range of 1.872 m3/s to 3.510 m3/s with the probability of the flow exceeds or equal to the design flow in range of 29.2% to 8.9%. In the energy calculation, the amount of 0.063 m3/s has been deducted from the available daily flow for the ecological flow. It shows that the energy output for the plant 4MW and 7.5MW would be in range 23 589 MWhr to 28 636 MWhr, respectively. The plant factor of the plant based on all the scenarios are 67.32% for the 4MW plant and 43.59% for the 7.5MW plant. Based on the hydraulic parameters, it was found that the most suitable type of turbine for the plant would be pelton turbines. Based on the relationship between installed capacity, energy output and plant factor, it concludes that the optimum installed capacity is at 5 MW plant.

Aceh is one of the most earthquake-prone regions in Indonesia. It is, therefore, essential to design seismic resistance structures according to applicable standards. To reduce damage to building structures, the Indonesian government has updated the seismic-resistant design code for building and non-building structures. The seismic resistant design standard has been updated from SNI 03-1726-2012 to SNI 03-1726-2019 due to a significant change in spectrum response data. The purpose of this study was to evaluate and compare the impacts on the seismic base shear and the cross-sectional area of columns, beams, and tie beams of buildings in 23 regencies in Aceh Province based on SNI 03-1726-2012 and SNI 03-1726-2019. A typical five-story office building with medium-type soil is used in the study. For structural analysis, a particular moment-resistant frame was considered. The determination of the design response spectra is carried out by using coordinates and soil types through the website “indo spectra”. The method used is spectrum response analysis. Some different requirements in the two standards include the spectrum response curve, mass participation, and dynamic base shear. The study’s results revealed that the dynamic base shear in Sabang City had grown by 192.05 percent. Aceh Barat Daya Regency was observed to have the smallest increase in dynamic base shear, which was only 8.16 percent. The required cross-sectional area of structural columns, beams, and tie beams in Sabang City increased by 96%, 40%, and 44.44%, respectively; in the meantime, the required cross-sectional area of columns, beams, and tie beams in several regencies in Aceh province remained unchanged.

A foaming agent is a concentrated solution of surfactant material that must be dissolved in water before mixing with other concrete material. The foaming agent is used to produce lightweight concrete with a density is £ 1.900 kg/m³. Using foam agents may affect the compressive strength and absorbency of the concrete. Hence, adding clam shells is expected to improve the compressive strength of the foam concrete. In addition, it is also essential to investigate the effects of utilizing foam agents and clam shells on the density of the foam concrete. Nine concrete mixes namely 1 variation of standard concrete, four variations of concrete mixes with foam agent, and four variations of concrete with foam agent and calm shell have been studied to investigate the parameters.The variation of foam agents in the eight concrete mixes were 5%, 10%, 15%, and 20% by water weight. The last four variations contained clamshell of 5% by weight of fine aggregate. The foam agent wasfoamingduced by mixing with a ratio of water and foam agent of 40:1. The experimental results show that at the variation of 20% foam agent, the density reduced by 34.55% and 26.89% for foam concrete with and without clam shell compared to normal concrete. I contrast, adding clamshell also lowered down the compressive strength of foam concrete by 79.86% and 74.96% for the variations. Meanwhile, the highest absorption rate of 1.65% or increased about 6.45% from normal concrete occurred at a variation foam agent of 15% mixed with clamshell. It was concluded that the use of clam shell in the foam concrete seems to decrease the strength of the foam concrete. However, in terms of density, the use of clam shells benefits foam concrete by lowering the self-weight of concrete.

Multi-storey buildings are very susceptible to lateral forces, so reinforcement is needed to stiffen the building by adding a system of stiffeners to the building structure. In steel building structures, the system of stiffeners bracing and confessor shearwall can provide rigidity and strength by limiting the movement of the structure. In addition, the placement of stiffener systems in the right locations can also increase the rigidity of the building structure. This study aims to compare the effectiveness of structural behavior using a stiffener system based on the value of the fundamental period (T), the base shear force (V), the drift between stories (?x). In this research using a steel structure model that functions as an office building with a height of 10 levels, one variation of the model without stiffeners and four models with stiffeners, with two variations of the position of the stiffeners, namely in the middle and on the edge of the structure. The results of this study indicate that the addition of a stiffener system can increase the rigidity of the structure. The most effective structural model is found in the structural model with stiffeners shearwall the stiffener position in the middle which has a fundamental period value in the X and Y directions of 17.67% and 18.32% is better than the other models. For the base shear force values in the X and Y directions are 0.95% and 0.95% smaller than the other models. The deviation values between floor levels in the X and Y directions are 9.67% and 34.17% better than the other models. Meanwhile, the inefficient structural model is found in the structural model with stiffeners bracing on the edge which has a fundamental period value in the X and Y directions of 8.96% and 9.32% which is no better than the other models. For the base shear force values in the X and Y directions are 18.02% and 18.02% greater than the other models. The deviation values between floor levels in the X and Y directions are 1.69% and 13.15%, not better than the other models. So in this study it can be concluded that the stiffener system with a position in the middle is better than the position on the edge.
