Abstract

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

Abstract

Population growth and economic factors are the causes of changes agricultural land supply chain use in North Aceh District. The regional development requires land for housing, industry, trade and other purposes while land availability was constant, resulting in land conversion from the function of agricultural land supply chain to non-agricultural. The shifting of land use from 2012 to 2015 was significant in the reduced farm forestry 7,138 ha, agricultural estate 6,465 ha and Wetland area of 227 ha. The purpose of this study was to determine the significance of the effect of population growth and economic factors on the conversion of agricultural land supply chain into non-agricultural land supply chain. The method used was Quantitative Method by using Structural Equation Model (SEM). The results showed that population growth and economic factors affect the conversion of land from agricultural land supply chain to non-agricultural land supply chain, especially in urban areas. The shift in the dominant production area for housing, store shops because it is more profitable as a place of business in increasing peoples income but this causes the reduction of agricultural land supply chain as a support food support

Abstract

Krueng Peudada River is located in sub district Peudada, Bireuen District, empties into the Strait of Malacca with a area watershed (catchment) of 425.8 km2. Water discharge is contributed by Krueng Wie River and Krueng Uneuen River. Subdistrict Peudada is an area prone to flooding, therefore the government made reservoir in the Meunasah Lawang village as an attempt to utilize the excess water as water source and as a flood control. Return period flood discharge plan is calculated by empirical formula method of Gumbel Type I. The result study shows the largest flood discharge at 50-year return period 333,282 m3/sec. To cope with likely flooding the reservoir Krueng Peudada planned dam height (H) 35 m and a summit elevation of +55 m and the area of 16,534,168 m2, so the total reservoir volume Peudada reservoir 329,419,094.58 m3. Volume used for water for all needs supply taken in an effective volume that is equal to 233,236,063.20 m3. The availability of water current (existing conditions) reached 0.971 m3/det, while the water needs for all the needs of 24.557 m3/det. In general, if there is a prolonged dry season, the water needs for all conditions can not be met.

Abstract

Perkerasan jalan AC-BC yang terlalu dini rusak tidak sesuai dengan umur rencana biasanya di sebabkan oleh faktor beban berlebih dan mutu campuran aspal itu sendiri. Dewasa ini telah banyak diteliti tentang bahan pengisi (filler) dari material lokal yang banyak digunakan dan ramah lingkungan untuk memodifikasi sifat-sifat aspal dalam campuran aspal beton sehingga dapat memperbaiki kinerja perkerasan dari sisi nilai-nilai parameter Marshallnya. Penelitian ini membahas mengenai pengaruh kadar filler abu batu kapur (ABK) dan abu tempurung kelapa (ATK) pada perkerasan jalan AC-BC dengan metode Spesifikasi Umum Bina Marga Revisi 3. Masalah yang ditinjau adalah karakteristik Marshall, dengan membandingkan perilaku campuran AC-BC yang menggunakan filler ABK dan ATK dengan campuran normal. Pada penelitian ini KAO yang didapatkan sebesar 6 % dan untuk benda uji dengan filler ABK dan ATK dengan variasi 100:0, 0:100, 25:75, 50:50,75:25. Hasil pengujian di laboratorium perbandingan nilai stabilitas menunjukkan nilai stabilitas yang didapat dari penggunaan filler ABK dan ATK dengan metode spesifikasi Bina Marga 2010 revisi 3 meningkat dibandingkan dengan tanpa ada penggunaan filler ABK dan ATK yaitu nilai stabilitasnya sebesar 1562,95 kg, sedangkan campuran normal sebesar 1430,19 kg. Untuk nilai density, VFWA, stabilitas, dan flow mengalami peningkatan pada semua variasi,  sedangkan nilai VMA, VITM, dan MQ mengalami penurunan dan masih dalam spesifikasi yang disayaratkan, selanjutnya untuk nilai durabilitas adalah sebesar 80,3%, nilai tersebut belum memenuhi nilai yang disyaratkan. Pada penelitian ini hanya pada variasi filler 25% ABK dan 75% ATK yang menunjukan seluruh nilai parameter Marshall telah memenuhi Spesifikasi Bina Marga 2010 Revisi 3.

Abstract

Abu batu bara terdiri dari partikel-partikel halus, gradasi dan kehalusan abu batu bara dapat memenuhi persyaratan gradasi untuk mineral filler. Penggunaa filler pada campuran aspal beton adalah untuk mengisi rongga dalam campuran, untuk mengikatkan daya ikat aspal beton, dapat meningkatkan stabilitas dari campuran aspal beton. Tujuannya dari penelitian ini adalah untuk mengetahui perubahan nilai Parameter Marshall akibat pengaruh penggunaan abu batu bara sebagai pengganti filler dengan beberapa variasi campuran. Metode penelitian menggunakan Metode Marshall dengan rujukan Spesifikasi Bina Marga tahun 2010 Revisi 2. Hasil penelitian didapat nilai Flow pada campuran aspal mengalami peningkatan pada kadar 25% abu batu bara nilai sebesar 3,30 mm dan kemudian meningkat sebesar 0,91% menjadi 3,33 mm pada kadar 50% abu batu bara,  kemudian terus meningkat seiring bertambahnya kadar abu batu bara seiring bertambahnya kadar abu batu bara dalam camputran,hal ini disebabkan nilai VIM dapat menerima kadar abu batu bara bertambah dan rongga dalam campuran bertambah licin.Sedangkan nilai stabilitas pada campuran aspal mengalami penurunan dimulai pada kadar 25% abu batu bara nilai stabilitas sebesar 1431 kg kemudian menurun sebesar 70,79% pada kadar 50% abu batu bara sebesar 1418 kg nilai stabilitas mengalami penurunan seiring bertambahnya kadar abu batu bara dalam campuran. Hal ini disebabkan oleh menurunnya penggunaan butiran abu batu yang mengakibatkan film aspal menjadi tebal, sehingga fungsi aspal sebagai pengikat berubah menjadi pelicin dan akan menurunya nilai stabilitas.

Abstract

Structural degradation caused by sudden damaging extreme events (e.g. earthquake) has significant impact on residual life of bridges and ultimately the collapse of bridges. This paper presents a reliability-based approach of a bridge subjected to shock degradation caused by earthquake events. In particular, this study develops a numerical procedure for assessing time dependent probability of failure to estimate the residual life a bridge. Key factors that govern the residual life of a bridge (e.g., damage size caused by earthquake shocks and loss of initial structural capacity) were investigated. The results of study show that both damage size caused by earthquake shocks and loss of initial structural capacity are key factors that govern residual life of a bridge. Keywords: residual life, earthquake, shock degradation, bridge.

Abstract

Slope in the drainage channel system is a primary factor that determines the quantity of water to be gravity discharged. By having bigger slope, the flow velocity becomes larger and the capacity of water discharged becomes more so that there will be no surface runoff. Lhokseumawe is a city located in the coastal area with its height is only 0.95 m above sea level. It is difficult to build the appropriate slope of the channel. For this reason, innovation is needed by modifying the slope of the channel in stages and tiered at each distance of 50 m, by which for channels along the 1,350 m will have 27 stages. The discharge capacity required to flow the rainfall is based on a 2-year return period of 5.10 m3/ sec. Slopes under normal conditions are 0.0013 to get a flow velocity of 1.27 m/sec. Using a section area of 1.32 m2 channel it can get discharge capacity of 1.67 m3/ sec. Furthermore, the slope of the channel was modified to 0.005 at each distance of 50 m and this obtained a flow velocity of 2.46 m/sec so that it was able to drain a discharge capacity of 3.24 m3/ sec. By modifying this channel slope can increase the discharge by 1.57 m3/sec or 93.7% compared to the slope without modified. It has not been able to multiply the overall discharge but at least can reduce the discharge 93.7%.
