Abstract

Keterlambatan jadwal pada proyek konstruksi merupakan salah satu masalah yang dapat merugikan berbagai pihak pada proyek. Critical Chain Project Management (CCPM) adalah suatu metode penjadwalan yang dapat menjadi solusi alternatif dari permasalahan pengendalian jadwal tersebut. Metode ini ditempuh dengan cara menghilangkan multitasking, student syndrome, parkinson’s law serta memberi buffer di waktu akhir proyek. Penelitian ini bertujuan untuk membandingkan metode CCPM tersebut dengan metode Critical Path Method (CPM) pada studi kasus proyek Pembangunan Apartamen Menara Rungkut, Surabaya yang tengah berjalan. CPM sendiri adalah metode penjadwalan tradisional yang masih menggunakan waktu cadangan pada setiap aktivitas untuk melindungi aktivitas-aktivitasnya. Penjadwalan awal proyek menggunakan metode penjadwalan tradisional berupa gantt chart yang kemudian di-breakdown lebih detail dan lengkap dengan hubungan antar aktivitasnya ke dalam bentuk CPM, dan kemudian akan dibandingkan dengan hasil dari penjadwalan CCPM yang telah menghilangkan multitasking, menghilangkan Safety time pada tiap aktivitas dan memberi buffer dalam pengerjaannya. Dibandingkan dari segi waktu, hasil penelitian ini didapatkan durasi waktu untuk CCPM adalah 121 hari lebih cepat 48 hari jika dibandingkan dengan metode CPM.

Abstract

Seiring dengan kebijakan pemerintah terkait pembangunan infrastruktur, maka pelaksanaan proyek infratuktur juga harus berjalan dengan baik. Oleh karena itu perlu adanya pengukuran kinerja pada proyek infrastruktur. Penelitian ini bertujuan untuk mengukur kinerja biaya dan waktu proyek Jetty dengan menggunakan metode earned value analysis. Earned Value (EV) adalah sebuah metode yang dapat mengukur kinerja sebuah proyek dengan mengintegrasikan biaya dan waktu. Hasil penelitian menujukan bahwa kinerja proyek pembangunan Jetty PT. Kias yang berlokasi di Manyar, Gresik mengalami keterlambatan dari jadwal yang sudah direncanakan. Ini ditandai dari nilai SV yang berada pada posisi negatif dan SVI yang kurang dari nilai 1. Jika kinerja ini tetap dipertahankan oleh kontraktor, kontraktor selaku pelaksana proyek juga mengalami kerugian keuangan bila dibandingan dengan anggaran rencana yang ada.

Abstract

Linear programming can be an alternative in solving problems in the construction sector. In construction work there is a workforce, but the allocation of the number of workers used requires good planning. If the allocation of the number of the worker is optimal, then the costs incurred for labor wages are also more efficient. For this reason, this study aims to optimize wages and the number of workers in construction projects. In performing optimization, the method used is simplex analysis. The simplex method is a linier program that can be used more than 3 variables, to solve the problem by iterating or recalculation until it reaches the optimal solution. The results of this are a decrease in the cost of labor wages, for concrete work there is a decrease in the cost of labor wages by 8,60%, and ceiling work there is a decrease in the cost of labor wages by 58,59%.

Abstract

Background: Air pollution is a very serious problem nowadays. Air pollution can be caused by the problem of haze from forest fires that occurred in 2015 & 2019 in Province Riau & Jambi. The worst conditions occurred in the period 1997-1998 and in 2006-2007. In 2015 & 2019 the haze conditions returned to the 1997 period. Province Riau & Jambi contributed to the largest hotspots in forest fires compared to North Sumatra or Kalimantan. The increase in the haze that has continued for the past three months is very worrying because the haze is getting worse and thicker, making the visibility of the affected areas even smaller. The purpose of this research to know the capabilities being run the Riau provincial government has been in control of who impressed off guard because repeated continuously, and whether factors constr ai nts and defienc e i nflu enci ng th e c apab i li ti es of th e Province Riau & Jambi government. Method: Descriptive research is research that aims to describe, describe and analyze existing events and aims to obtain information about the impact of the haze in Province Riau & Jambi with existing theories so that it can be used in mitigation in different places. Findings: The urgency in this study to see why the Province Riau & Jambi government off guard so persistent, because the capabilities of the system and the process will involve considering the fire that occurred not once or twice only. Conclusion: The main causes of forest and peatland fires in Riau are human activities, such as the use of fire for land clearing and agricultural practices, combined with natural conditions like dry land and extreme hot weather. These fires significantly impact human health, social interactions, and the environment, necessitating critical awareness among farmers to act responsibly and monitor fire spread to prevent future losses. Novelty/Originality of this article: By analyzing the inhibiting factors and definitions that influence local government capacity, this study opens new insights into the complexity of environmental disaster management involving interactions between human activities, natural conditions, and institutional capacity.

Abstract

The current climate change is characterized by an increase in the earth's surface temperature; one of the impacts that is felt quite significantly is the thermal comfort conditions in buildings. This will encourage residents to use air conditioning to provide the required level of thermal comfort. From the results of electricity demand forecasts, from 2017 to 2036, electricity demand will increase by 6.4% annually, dominated by the household sector at 38.49%. Efforts can be made to condition the room's thermal comfort to reduce the AC's operating time. This can be realized through building energy retrofitting, especially in middle-low-income households. Retrofitting will also not require high costs, so it suits middle-low-income households. In this research, retrofitting was carried out by implementing ventilation. It is hoped that ventilation will naturally provide air to specific rooms through air movement and exchange. This study implemented 12 variations in ventilation, namely variations with cross ventilation and non-cross ventilation, then varied the size of the ventilation and the number of ventilations. This research was carried out based on simulations using Computational Fluid Dynamics. After carrying out the simulation, it was obtained that the most significant decrease in indoor temperature was when cross ventilation was applied at night with ventilation measuring 30 cm x 70 cm with a total of 4 vents, namely with a decrease in the average indoor temperature of 1.614C. After that, a cost-benefit analysis was carried out to compare the costs and benefits of a project; a cost-benefit ratio of 1.26 was obtained, where the profits were more significant than the expenditure costs, a payback period value of 0.402 was obtained, or the capital could be returned for five months, and savings were obtained. Electricity consumption costs up to year five amount to IDR 24,340,306.

Abstract

The phenomenon of the Lapindo Mudflow that occurred on May 29, 2006, in Sidoarjo, East Java Province has entered its 17th year after the disaster with a continuous overflow until now. One of the disaster mitigation methods to handle the threat of wider mudflow to more densely populated areas is with the construction of embankments. Glagaharum Village on Porong is directly adjacent to the outer barrier with a distance of ± 500 meters, and between the village and the embankment is only a meter-wide tributary before reaches the village road. This research was arranged descriptively with a quantitative method. This method was used to find out the community's knowledge about evacuation routes and places through questionnaires. Researchers used the parameters of age, gender, and education as a binary logistic regression test. The binary logistic regression test showed that the education parameter had more influence on knowledge of evacuation locations; next was gender, and lastly was age. Education influences education level, literacy level, and critical thinking skills. Meanwhile, the female gender had difficulties regulating emotions when circumstances were urgent. So, the importance of increasing literacy and adding special training for women was needed to increase equality in the knowledge of evacuation locations.
