Abstract

Management of market organic waste in Balikpapan City is an important thing to do to reduce the burden on Manggar TPA. Organic waste, especially market organic waste, which continues to increase along with the rapid growth of the population in Balikpapan City as a buffer city for the IKN can increase the risk of environmental pollution and safety. Market organic waste can be used as an alternative feed for cattle and goats and this has been done by the Sumber Makmur Farmer Group, Gunung Tembak, Balikpapan City. In addition to utilizing market organic waste as cattle and goat feed, the Sumber Makmur Farmer Group has also managed cow manure in the form of solid and liquid into solid organic fertilizer and liquid organic fertilizer. Thus there has been a series of Economy circular which can be an alternative in overcoming the problem of market organic waste in the Balikpapan city as well as increasing economic value. The method in this study uses a descriptive-qualitative method with a design action research model or action research by observing directly to obtain information from the object of study. Discussion of this research is divided into 4 parts such us System for Utilizing Market Organic Waste as Cattle and Goat Feed, the system for utilizing solid cow manure, the system for utilizing liquid cow manure, the potential for managing cattle and goat farms based on an economy circular. The results of observations at the Sumber Makmur Farmer Group, Gunung Tembak, Balikpapan City, show that there have been livestock management activities that apply an economy circular from upstream to downstream. Furthermore, it is hoped that further and in-depth research can be carried out in terms of economy circular-based livestock management in the utilization of organic waste as animal feed so that it can provide more comprehensive information to the wider community so that they can implement this system. Keyword: market organic waste, farming, animal feed, economic circular, manure

Abstract

BIM hadir sebagai bukti perkembangan teknologi digital yang telah mempengaruhi dan memberikan manfaat di lingkup pekerjaan konstruksi, mulai dari perencanaan proyek, penjadwalan proyek, pengelolaan proyek, manajemen bangunan dan lain – lainnya.  Dalam menghitung anggaran biaya proyek harus dilakukan se-efisien mungkin untuk menghindari terjadinya pembengkakan biaya pembangunan. Oleh karena itu pada penelitian ini menggunakan konsep Building Information Modelling (BIM) 5D yang bertujuan untuk menganalisis selisih volume dan estimasi biaya antara metode BIM dengan perhitungan konsultan pada pekerjaan struktur Graha Sucofindo Balikpapan. Dari hasil perhitungan menggunakan konsep BIM 5D didapatkan selisih biaya pekerjaan pembesian sebesar Rp. Rp. 123.946.941,75 dengan persentase selisih sebesar 7,34% dan untuk selisih biaya pekerjaan pembetonan sebesar Rp. 234.507.945,47 dengan presentase selisih sebesar 30,32 %. Hasil dari perhitungan ini menunjukkan bahwa menggunakan konsep BIM 5D pada pekerjaan pembesian dan pembetonan dapat menghemat total biaya sebesar Rp 312.943.542,70 dengan persentase mencapai 12,71%. Hal ini berarti bahwa perhitungan biaya dengan konsep BIM 5D lebih rendah dibandingkan dari perhitungan biaya yang dihasilkan oleh konsultan. Hasil ini juga menunjukan bahwa implementasi BIM 5D di Autodesk Revit lebih efisien dalam perhitungan volume dan estimasi biaya.

Abstract

Building Information Modeling (BIM) represents a technological advancement in the modern era that continues to develop, particularly in the construction industry, by supporting planning and capital management. One of the software applications that can be used to support BIM is Autodesk Revit. The objective of this research is to compare the results of cost estimation for building structures using conventional methods and BIM, applied to a type 400 residential house project located in Balikpapan, East Kalimantan Province, within the Grand City housing area. The study focuses on calculating structural work costs, highlighting significant differences in structural components, particularly in reinforcement and concreting work. The findings indicate a cost difference of 16.82% in reinforcement work and 12.7% in concreting work, resulting in an overall budget estimation discrepancy of 15.62%. Based on these results, this study concludes that the use of BIM is highly necessary for identifying and evaluating cost estimation in building or construction planning from the perspective of project planners.
