Abstract

Pada proses pembangunan JDU SPAM WOSUSOKAS Segmen 3 Kabupaten Sukoharjo tidak luput dari segala bentuk risiko yang akan dan telah muncul. Risiko tersebut dapat berpotensi menimbulkan kerugian baik minor atau pun mayor yang dapat merugikan proyek pada aspek biaya dan waktu, berbagai pihak yang menjadi Stakeholder tidak ingin kerugian tersebut berdampak pada mereka. Penelitian ini mengemukakan bahwa terdapat Sembilan risiko yang menjadi prioritas untuk ditangani, risiko tersebut berhubungan tentang aspek pengendalian biaya dan waktu. Setelah penetapan Sembilan risiko prioritas dipilihlah 15 strategi penanganan untuk mencegah kerugian meluas dan menjadi acuan proyek Pembangunan JDU SPAM WOSUSOKAS Segmen 3 pada penanggulangan risiko tersebut.

Abstract

Climate change and global warming have become major global concerns due to their significant impacts on the environment and human life. One of the primary contributors to climate change is Greenhouse Gas (GHG) emissions, which are generated by various industrial activities, including the construction sector. PT Kaltim Methanol Industri, one of Indonesia's largest methanol producers, plans to add a new unit for CO₂ injection to enhance its production capacity. In this new unit, the reciprocating compressor machine foundation is a crucial structural component that must not only meet technical requirements but also consider environmental impacts, particularly GHG emissions produced during the construction process. This study employs the Life Cycle Assessment (LCA) method to identify the life cycle stages that contribute the most to GHG emissions and to compare the GHG emissions of various foundation types, namely standard block foundation, spring-supported foundation types 1, 2, and 3. The dimensions of each foundation type are 10.2 m in length and 6.2 m in width, with varying heights: standard block foundation (1.5 m), spring-supported type 1 (1.25 m), spring-supported type 2 (1.0 m), and spring-supported type 3 (0.75 m). The height above ground for each foundation type is 0.35 m. The study results indicate that the raw material stage contributes the most emissions, with the highest emissions recorded in the standard block foundation at 65,969.8476 kgCO₂e. Meanwhile, the foundation with the lowest emissions is the spring-supported type 3, producing 36,550.0597 kgCO₂e.

Abstract

Background: Annona muricata L. (A. muricata) leaf contains several active compounds, including flavonoids, which are known to have antioxidant properties. People only use A. muricata leaves as antioxidants by boiling them in water. Therefore, the development of tablet potential is necessary to enhance user comfort and storage stability.Objective: The aim of this research was to determine the disintegration time of A. muricata leaf extract tablets with varying levels of the disintegrating agent crospovidone and to determine the best disintegrating level according to the results of evaluating the physical properties of the tablets.Methods: Tablets are made using the wet granulation method with a composition of 2-5% crospovidone. The resulting granules are tested for water content, flow time, angle of repose, and tapping. The resulting tablets were tested for hardness, friability, and disintegration time.Results: The test results show that crospovidone and lactose can produce excellent A. muricata leaf extract tablets.Conclusion: Crospovidone 3.5% produces optimum A. muricata leaf extract tablets with a friability of 0.36% and a disintegration time of 7.82 minutes.
