Abstract

The fact that construction causes negative impact to the environment such as degradation of environmental quality that caused by the increasing of waste volume produced by construction activity. Based by research around the globe, it is said that more than 50% of waste are produced by construction activity (Wulfram Ervianto, 2012). The increasing of construction waste comes from a construction process. If large amount of construction waste produced, so analogically the natural resources that exploitated has a large of amount of volume either. So it needs a right management to overcome by appliying a responsible construction process so that the waste that produced will be decreased. In its development, that construction process is known as green construction. This research will discuss about the comparison between the amount of waste that produced during the processing of the 1st and 2nd floor of upper structure work between green construction and conventional project based on implementation method applied by each project. Research method used such that qualitative method with description and data derivation by direct observation and interview on field with case study of construction project of Mataram City Yogyakarta Hotel and Apartment with PT. Pembangunan Perumahan (Persero) contractor as an object of green construction project and Hotel 101 Yogyakarta one with PT. Bintang Sewu Sejahtera as an object of conventional project. From the observation result, the fact that waste on green construction project is considerably less than conventional is obtained, that is with percentage of bar reinforcement waste 0.54%, wood/plywood 4.85%, and concrete 0%.  It shows that selecting the implementation method and waste management precisely can decrease material solid waste.

Abstract

Industri konstruksi merupakan industri yang memiliki tingkat kompleksitas yang sangat tinggi. Tercermin dari banyaknya tahapan dalam suatu siklus hidup proyek atau Life Cycle Project. Dari semua tahapan tersebut, tahapan implementasi (construction) merupakan tahap yang perlu mendapat perhatian yang serius, karena pada tahap ini harus tercapai tepat waktu, tepat biaya, dan tepat mutu atau yang sering disebut sebagai triangle project constraint. Untuk itu diperlukan sistem manajemen proyek yang baik seperti ditawarkan oleh Konsultan Manajemen Konstruksi (KMK). Penelitian ini bertujuan untuk mengidentifikasi dan membuat instrument pengukuran kinerja  KMK pada tahap implementasi. 5 indikator kinerja yang dikembangkan menjadi 22 variabel digunakan untuk mengukur kinerja KMK pada proyek pemerintah dan pada proyek swasta. Selanjutnya dilakukan analisis dengan tiga metode yaitu metode analisis kesenjangan (GAP), Importance Performance Analysis (IPA), dan Customer Satisfaction Index (CSI). Dari hasil analisis dan perhitungan pengukuran kinerja KMK yang diukur dengan  metode analisis GAP dan IPA secara garis besar menunjukan bahwa kinerja KMK pada proyek swasta memiliki kinerja yang lebih baik dibandingkan kinerja pada proyek pemerintah, didapatkan pula nilai CSI untuk kinerja KMK pada proyek pemerintah sebesar 52,51% (cukup puas) dan CSI untuk kinerja KMK pada proyek swasta 85,88% (sangat puas).

Abstract

Every construction project especially for PDAM project which responsible for water distribution has some risk that affect the construction. One of the common problems which became risk for the PDAM project is the pipe leakage level. The average of indonesia’s pipe leakage level is more than 30%. This research is about risk management of IPA Kaligarang piping project analyzing based on Work Breakdown Structure (WBS). The aim of this research is to identify, analyze, evaluate and manage the existing risk of IPA kaligarang piping project. The matter of this research is limited for the construction phase. IPA Kaligarang Piping project is a project of West Semarang PDAM. Based on identification and risk assessment, IPA Kaligarang West Semarang PDAM piping project had 23 risks which is found almost at each Work Breakdown Strukture(WBS) project. For then more through analyzing and evoluation process, the result of this research is the risks of PDAM projects consist of two categories. The categories are moderate risk which has 14 work items (39%) and low risk which has 74 work items (61%). The whole 23 risks that found can be managed, like permitting risk can be managed by asking government approval, The risk of workers excalation or reduction can be managed by making the barchart of workers or reschedule, etc. The contractor is the one who responsible of the whole risk, and there’s no high risk that will obstruct the construction of IPA Kaligarang West Semarang piping project.

Abstract

Sedimentation in the estuary of the Bodri River have a major impact on the flooding problems in the area around the Bodri River. To overcome this by planning Normalization Pecut River which has a large enough funding, so it is necessary to value engineering. The purpose of this paper is to obtain solutions to problems of sedimentation, coastal erosion, seawater intrusion and flooding, know the function and cost of the initial design (Normalization Pecut River), as well as getting the design alternatives (Re-naturalization Bodri Lama River) as a substitute for the initial design, which is further than the value of the function and cost. In terms of the normalization function Pecut River hydrologic analysis of the calculation results obtained by the discharge of floods over 25 years, the amount of Q25=18.236 m3/sec. The amount of sediment transport Pecut River, is 47.267 tons/year. Results hydraulics analysis with HEC-RAS program occurs runoff groove along the river, which means there is a flood. To Re-naturalisation Bodri Lama River flood discharge when re-used 50 years the amount of Q50=61.58 m³/sec. With the Renaturalisation of Bodri Lama River can reduce flood discharge in Bodri River at 5.73%. Old Bodri river sediment transport, amounting to 159.408 tons/ year. The results of the HEC-RAS program checks the water level in the re-naturalization of the Bodri Lama River be lower, so the plan is safe from flooding. In terms of costs for normalization Pecut River RAB calculation results obtained by Rp.34.269.498.000,00 (in words: Three-Four Billion Two Hundred Sixty-Nine Million Four Hundred Ninety Eight Thousand), to Renaturalisasi Bodri Lama River at Rp.10.362.242.000,00 (in words: Ten Billion Three Hundred Sixty-Two Million Two Hundred Forty-Two Thousand). Based on the analysis of value engineering, Renaturalisasi Bodri Lama River generate cost savings of RP. 23,907,256,000.00 (in words: Twenty-Three Billion Nine Hundred and Seven Million Two Hundred Fifty Six Thousand Rupiah).

Abstract

Construction project have problems regarding waste, which can be in forms of Physical Construction Waste and Non-Value Adding Activity. The purpose of this research is to evaluate waste that occured in construction projects, while the aim of this research is to know the frequency and impact of waste, as well as the waste cause factor. The object of the research was waste on building project in the area of Semarang. Waste identification was carried outfrom literature, observation and interview and wereanalyzed using fishbone diagram to get waste cause factor variable. Waste variables were divided into four categories, i.e. waiting periods, material, human resources, and operations. Waste cause factor variables were grouped into six categories, i.e. people, professional management, design and documentation, materials, execution and external.Questionnaires were distributed to 100 respondents of 12 different contractors, with response rate of 65%. Data was processed by Weighted Mean Score (WMS) method. The results of this research showed that “extra work” waste had the highest frequency, “rework and repair” waste had the highest impact, and “slow drawing revision and distribution” and “design changes”, were the highest waste cause factors on building projects in the area of Semarang. The results of data processing also showed that structural works was type of work where waste often occurred. The result of risk-waste matrix showed that “extra work” was included into high risk-waste category which means it could cause serious disruptions to the project execution and company’s finance.

Abstract

Perubahan iklim global yang terjadi saat ini sangat mempengaruhi lingkungan hidup manusia, hal ini juga mempengaruhi perubahan karakteristik iklim atau cuaca, halmana durasi musim hujan kadang memasuki pada musin kemarau / panas demikian juga sebaliknya, secara umum durasi musim hujan makin pendek, sebaliknya durasi musim kemarau makin panjang. Jumlah hari hujan cenderung semakin menurun, sementara hujan harian maksimum dan intensitas hujan cenderung semakin meningkat. Banyaknya lahan hijau yang berubah menjadi bangunan atau permukaan tanah yang tertutup akan mengakibatkan semakin meningkatkan limpasan air permukaan juga berakibat pada menurunkan resapan air ke dalam tanah. Kecamatan Tembalang merupakan salah satu wilayah di Semarang yang mengalami pesatnya pembangunan, hal ini bermula dari berdirinya kampus Universitas Diponegoro, kelurahan Bulusan merupakan salah satu wilayah yang terdampak akan hal tersebut, untuk itu maka tim pengabdian kepada masyarakat dari Teknik Sipil melakukan kegiatan Sosialisasi dengan pembuatan Biopori di wilayah tersebut sebanyak 24 buah biopori. Pelaksanaan kegiatan dilakukan di RW. V (RT.01, RT.02, RT.03 dan RT.04), diharapkan dengan diberikan bantuan pemasangan biopori beserta sosialisasi kepada masyarakat dapat meningkatkan semangat untuk melakukan swadaya di lingkungan rumah masing-masing, sehingga bisa memberikan dampak yang baik dalam mengatasi permasalahan banjir dan cadangan air tanahnya.

Abstract

Surface peak ground acceleration (PGAM) needs for seismic forces of basement and retaining structures design.  The PGAM value can be calculated using bedrock peak ground acceleration (MCEG) and multiplied it with site coefficient FPGA. For building design purposes, the MCEG value can be calculated based on the combination of DSHA (Deterministic Seismic Hazard Analysis) and PSHA (Probabilistic Seismic Hazard Analysis). Compared to the previous 2012 website response spectrum design which is displayed the PGAM value, only MCEG value at site position can be obtained from the new 2021 response spectrum design website. This paper describes the development of PGAM distribution of Semarang using Visual Basic programming language software. The distribution of DSHA and PSHA (2500 return periods) combination analysis for developing MCEG value also describes in this paper. The analysis was performed based on the earthquake record data from 1900 to 2016. The PGAM analysis was performed at 203 soil boring investigation positions and using FPGA site coefficients of SNI 1726:2019. The minimum and maximum PGAM distribution values at the study area are in between 0.45 through 0.55 g and the maximum PGAM is distributed at the northern part of the study area.
