“…The selection of the use of precast concrete is not only based on economic aspects, efficiency, and speed in its implementation [15]. However, it also relates to environmental impacts related to production inputs and outputs) [16]. The function of the Precast Half Slab method is as a structural component, namely a composite plate structure, so it needs to be reviewed from the point of view of technical analysis and structural efficiency [17].…”

This study aims to analyze the application of Precast Half Slab formwork with conventional formwork in terms of cost, time, and implementation stages. The method used in this study is the precast half slab method. The Batang I Industrial Worker Flats project is in the Batang Integrated Industrial Estate. In the highly advanced construction era, many projects compete to innovate to produce a fast and efficient building. This Project uses the precast half slab method, where half of the floor slab is printed offsite (precast) with a thickness of 7 cm, and the other half is in place (topping 5.5 cm). This final Project analyzes the precast half slab method used by comparing it to the conventional method in terms of cost and time, so it can be seen which method is more profitable. The precast half-slab method analysis focuses on calculating the direct cost of conventional half-slab precast in terms of materials, tools, and worker wages, as well as calculating the time needed for each job.

“…Untuk menentukan kategori dampak yang dijelaskan tersebut, maka dibutuhkan pula suatu metode untuk LCIA dalam LCA. Terdapat beberapa jenis metode yang dapat digunakan dalam LCA, diantaranya ReCiPE, CML-IA, USEtox,Ecoindicator 99, IPCC 2007, EPD, Impact 2002+, CML-IA, Traci 2, BEES, Ecological Footprint EDIP 2003, Ecological scarcity 2006, EPS 2000, Greenhouse Gas Protocol dan lainnya(Rakhmawati et al, 2020). Pada metode penilaian dampak berupa CML-IA yang memiliki 11 kategori dampak berupa midpoint impact category sebagai berikut abiotic depletion dan abiotic depletion (fossil fuel), global warming (GWP100), ozone layer depletion, human toxicity, fresh water dan marine aquatic ecotoxicity, terrestrial ecotoxicity, photochemical oxidation, acidification, dan eutrophication(Adiansyah et al, 2019).…”

Konsumsi energi dan penghasilan emisi gas rumah kaca telah menghasilkan peningkatan polutan ke lingkungan dari limbah kegiatan industri, salah satunya industri kelapa sawit yang sangat masif di Indonesia. Life Cycle Assessment (LCA) atau Penilaian Siklus Hidup merupakan metode yang dapat digunakan untuk menganalisis dampak lingkungan dari proses produksi pada industri kelapa sawit. Industri kelapa sawit dapat memberikan dampak terhadap lingkungan, seperti pencemaran udara akibat mesin, pencemaran air dan tanah akibat penggunaan pupuk dan pestisida, serta konsumsi air yang berlebihan. Tetapi hal ini dapat diatasi dengan menilai dan mendeteksi pada tahapan mana di industri kelapa sawit yang menjadi kontributor utama. Artikel ini memaparkan penerapan LCA pada sektor perkebunan kelapa sawit sebagai pendukung pengambil keputusan. Pendekatan Preferred Reporting Items for Systematic Reviews and Meta-analysis Item (PRISMA) digunakan untuk mengidentifikasi, menyaring, dan memasukkan artikel yang relevan. Mengidentifikasi artikel terkait penilaian siklus hidup di sektor perkebunan kelapa sawit yang memenuhi syarat untuk analisis menjadi salah satu metode penulisan. Temuan menunjukkan bahwa tren penelitian tentang LCA di sektor perkebunan kelapa sawit terbagi atas subsistem perkebunan kelapa sawit dan industri pabrik kelapa sawit. Dampak lingkungan yang ditemukan dalam artikel tersebut adalah parameter global warming potential (GWP dan asidifikasi. Didapatkan hasil bahwa penilaian LCA dapat menjadi salah satu pendukung pengambilan keputusan dengan berorientasi pada dampak lingkungan negatif terkecil yang dihasilkan dari suatu proses. Didapatkan bahwa pada industri kelapa sawit tahapan yang menghasilkan GWP terbesar ialah proses pemupukan dan pengelolaan limbah POME, sehingga pengambilan keputusan kedepannya dapat mempertimbangkan proses tersebut.

As one of the primary precast components in prefabricated construction, composite slabs have increasingly attracted interest for their costs as well as carbon footprint in production and installation stages. Conventional methods for separating composite slabs can lead to a building project necessitating multiple specifications of composite slabs. Due to the requirement to customize molds for different modulus of composite slabs, the production process experiences a substantial rise in energy consumption and resource waste. This not only increases production complexity and expenses but also indirectly raises carbon emissions. This paper conducts secondary development of a plugin based on the Building Information Modeling (BIM) technology platform, C# language and Visual Studio 2017 to optimize the modular design of composite slabs with the help of Revit software. This plugin can quickly and intelligently recommend the most suitable combination of composite slabs specifications based on the actual size of the floor slabs, thereby greatly reducing the types of composite slabs required. The modular optimization process developed in this paper is applied to an actual engineering project, the results show that the types of composite slabs molds after optimization are reduced from 9 to 4, and the mold cost is reduced by 69.60%. At the same time, the carbon emissions of the optimized composite slabs in the production stage are reduced by 7.03% compared with those before optimization. It is observed that this optimization scheme not only significantly reduces the production costs of composite slabs and improves production efficiency but also effectively reduces carbon emissions during the production phase of composite slabs.
