Abstract

Bridge that implement BIM can increase planning accuracy, reduce construction risks, and better plan the entire project. PTPP is a pioneer contractor that has implemented BIM in Indonesia since the end of 2015. The PTPP division that handles road and bridge infrastructure is Infrastructure 1. The aim of this research is to evaluate whether the BIM implementation is commonly carried out on PTPP bridge projects. The aim of this research is to evaluate the BIM implementation to the bridge project. This research method was used library research with a focus on the use of valid literature that already has previous research. The result of this research is that the BIM implementation to PTPP bridge projects is commonly used. All PTPP bridge projects since the end of 2015, a total of 3 projects have implemented BIM. Two bridge projects, Kendari Bay Bridge and the PIK 2 Connecting Bridge, North Jakarta, provide information about the implementation of BIM which can be accessed by the public via the official PTPP website and social media. Information on BIM implementation includes the process, software used, and the benefits on the bridge project. Meanwhile, for the Bogeg Bridge, Serang, no detailed information is available regarding the application of BIM. For the Kendari Bay Bridge project, the benefit of implementing BIM is that PTPP designed the bridge in just one month, saving three months. 3D model visualization really helps minimize errors and save time during the actual construction phase so that teams can collaborate easily using the same 3D model throughout the project. For the PIK 2 Bridge project, the benefits of implementing BIM include synchronous work drawings, helping with volume calculations, speeding up topographic surveis, detecting discrepancies, visualizing the project implementation schedule, helping coordinate with the project team, and helping with quality checks in the field.

Abstract

Used cooking oil (UCO) is abundant in Indonesia because of lifestyle of people. Especially UCO from street vendors had very low quality based on its Free Fatty Acid (FFA) content that reached 5.074%. When UCO was deposed into drainage, it would pollute the environment. Low grade UCO from street vendors contained Unsaturated-Fatty-Acid, Saturated-Fatty-Acid, and other hydrocarbons. Recycling UCO to replace edible oil considered more desirable rather than biodiesel since higher added value. FFA was the most undesired compound affecting cooking oil quality. FFA reducing with diluted 0.1 M NaOH 10% v/v could reduce FFA from 5.07% to 0.53%. Bleaching earth (BE) content mostly Si, Nb, Al, Ca and Na was safe to treat UCO for edible cooking oil. BE played cleaning UCO but absorbed the oil 17%. ANOVA analysis for BE and Moringa oleifera leaves (MOL) treatment fits with Reduced Quadratic model. Based on the ANOVA, the model showed that the decrease of FFA was determined significantly by BE amount and temperature with P-values less than 0.05. Optimization for BE treatment was done using Response Surface Method to find out the lowest FFA. And based on the simulation, it was obtained 0.2854% while the experimental results showed 0.2908%. Furthermore, BE combined with Moringa oleifera leaves (MOL) that known anti-oxidant source was used to treat UCO. UCO originally content stronger anti-oxidant activity rather fresh palm oil with IC50 62.12 and 83.03 mg/kg, respectively. Stronger anti-oxidant in UCO allegedly derived from fried foods. Treatment 10% BE and 5% MOL considered optimal for good appearance edible oil, little yellow greenish. Moreover, GC/MS analysis showed improvement active compounds in treated UCO with 5, 7.5 and 10 g MOL in 150 ml UCO with 24.36%, 30.32% and 37.76% active compounds, respectively. Moreover, anti-oxidant measured with IC50 the treated UCO were 43.18, 42.33 and 41.78 mg/kg, respectively. Increasing the number of MOL did not significantly increase the anti-oxidant activity. Anti-oxidant detected in treated UCO identified such as ethyl acridine, indolizine derivatives, cyclotrisiloxane-hexamethyl, benzimidazoles, and Fumaric acid. Based on the results, UCO recycling is applicable for a community, save expenses and strengthen food security and food sovereign. Further thought for its implementation is to design an integrated system from collecting UCO in a reservoir tank equipped with filter, recycling process and finally product tank at mini plant scale. Keywords: Anti-oxidant enrichment, bleaching earth, edible treated UCO, Moringa oleifera leaves (MOL) , UCO recycle

Abstract

The strengthening of globalization and the dominance of modern popular culture have contributed to the gradual fading of local cultural values, especially in rural areas that are rich in traditions. To respond to these challenges, community-based cultural events are used as an important strategy for cultural promotion and the development of sustainable tourism. This research aims to analyze the role of participatory communication in increasing tourism attraction and encouraging the advancement of Sundanese culture through the Pakuwon Earth Market event in Bantaragung Village, Majalengka Regency, focusing on its communication mechanisms, impacts, and strategies. This study uses a qualitative method, specifically a case study approach, in which data were collected through semi-structured interviews with three informants, participatory observation, and documentation studies, and analyzed using thematic analysis. The results indicate that dialogical, open, and inclusive participatory communication can increase awareness of Sundanese cultural values and strengthen community involvement by presenting meaningful tourism experiences. In addition, participation plays a role in transmitting cultural heritage values orally and strengthening a collective sense of belonging. This research concludes that participatory communication is an effective strategy for linking cultural advancement with the development of community-based cultural tourism and provides both theoretical and practical contributions to the development of sustainable tourism communication.
