Published: December 2024

Abstract
Concreting in construction often generates significant waste, but effective waste management can mitigate this. This study examines the impact of management policies on waste efficiency in the concrete pouring work of the Logung Dam project in Kudus. Using both quantitative and qualitative methods, the research analysis empirical data to understand observed phenomena. The quantitative analysis employs a statistical compare-mean test to assess concrete work efficiency, while qualitative analysis involves interviews with project stakeholders about waste management policies. Findings show that inadequate waste control and management systems lead to resource and budget wastage. In response, a new policy was implemented to improve concrete waste management. This policy includes procedures for managing leftover materials, work instructions for controlling the volume and weight of ready-mix concrete delivery and receipt, and detailed oversight of concreting work. Implementation led to positive changes, such as organizational structure modifications, a transparent and controlled ordering system, and Joint Inspections (JI). Following the policy implementation, waste management efficiency improved significantly, with the waste inefficiency level decreasing from 0.527% to -0.225%, reflecting a 0.752% efficiency increase. Although the correlation between policy changes and waste volume efficiency was positive, it was relatively weak.

Published: December 2024

Abstract
The increase in the number of visitors to Edupark Mangrove Camar has caused environmental degradation and damage to the mangrove ecosystem. Efforts to develop management and conservation strategies at Edupark Mangrove Camar need to be implemented. An important aspect of implementing these strategies is the participation of visitors as users of public goods to provide economic value for the use of mangrove forest tourism services. Willingness to Pay (WTP) is an approach to measure the economic value that visitors are willing to pay for development efforts at Edupark Mangrove Camar. The contingent valuation method (CVM), using the double bounded dichotomous choice (DBDC) bidding technique, is used to determine the amount of visitors’ bid value. The non-parametric estimation models Kaplan-Meier-Turnbull (KMT) and Spearman-Karber (SK) are used to estimate the average WTP value of visitors. To determine the factors influencing visitors’ WTP, binary logistic regression analysis is used. Based on WTPKMT and WTPSK, the average WTP values are obtained at Rp. 21,529 and Rp. 25,820, respectively. Based on the binary logistic regression analysis, it is found that the variables gender (female), high local ecological knowledge, and high awareness have a significant influence on WTP.

Abstract
Paya Nie Swamp currently faces a decrease in peatland area from 306 hectares in 2013 to 262 hectares in 2023. This occurred due to community activities that converted it into oil palm and rice fields. Whereas, peatlands hold carbon stocks three times higher than forests, and have major environmental values as water reservoirs. In Paya Nie, there are several illegal activities of the community taking endemic fish, namely snakehead fish using electric shocks, and lack of public awareness of local wisdom to weave purun and protect peatlands. Based on these problems, PT Pupuk Iskandar Muda took the initiative to develop the Paya Nie Lestari, Damai, and Berdaya programs in Blang Me Village, Bireuen Regency. The program is a concrete contribution to the company’s empowerment of the community and conservation of peatlands. The initiation of Paya Nie Lestari, Peaceful, and Empowered is in line with the goals of sustainable development, where the program’s implementation supports the fulfillment of the 10 SDGs. The three sub-programs in it have an integrated goal, which is to conserve peatlands by growing economic value, and implementing green lifestyle ecosystems to support sustainable development.

Published: December 2024

Abstract
The marketing paradigm shift towards 6.0 encourages industry players to focus more on green retail technology. Memorable Experiential Reality Technology (MERT) is receiving great attention for its ability to bring users into a virtual environment. MERT includes mixed reality (MR) which consists of virtual reality (VR) and augmented reality (AR). Using this technology is considered to reduce energy consumption from the consumer side, because with technology consumers can experience the experience directly without having to visit the retail industry or shopping centers that apply MERT. This study aims to determine the impact of technology on saving energy consumption from the consumer side and identify barriers to its application. Literature studies, case studies and consumer surveys were used to obtain data information in the field. The research findings are that experiential reality can significantly reduce energy consumption by offering experiences that encourage sustainable behavior among consumers. Through interactive simulations and virtual environments, consumers gain a deeper understanding of their energy savings and make informed decisions to minimize energy wastage. Barriers to technology adoption are limited infrastructure, high costs and lack of user awareness of the benefits of MERT in reducing energy consumption. Users need to be convinced that the investment of time and resources in using MERT will have a positive impact on the environment and overall energy consumption. Education and socialization on the positive effects of technology implementation are needed to help increase community adoption.

Abstract
Fly Ash and Bottom Ash (FABA) is waste from coal combustion originating from Steam Power Plants. This waste has chemical content in the form of silica, aluminum oxide, and lime. Previous research stated that Oil Palm Empty Fruit Bunch can increase the mechanical strength of the building material and prevent the propagation of cracks due to loads. The use of additional ingredients FABA and Oil Palm Empty Fruit Bunch in the red brick mixture aims to determine the characteristics of red brick in the form of compressive strength and water absorption values. The test was carried out at the Civil Engineering Laboratory at Bangka Belitung University using 100 red brick samples. The percentage of FABA used in this research is 10% (5% fly ash and 5% bottom ash) calculated from the weight of the clay, while the percentage of Oil Palm Empty Fruit Bunch used is 0%, 5%, 10%, and 15% is calculated from the weight of the clay. The results of this test show that red bricks with the addition of 10% (5% fly ash and 5% bottom ash) FABA and 0% Oil Palm Empty Fruit Bunch increased the compressive strength value of normal red bricks and can reduce water absorption.
Study of the Connection Between Yogyakarta – Sleman Groundwater Basin and Pajangan Hill (as a Non-Groundwater Basin Area) Using Groundwater Geochemistry and Isotope
Authors: Hadameon Y , Hendrayana H , Dirgantoro M F 
Published: December 2024

Abstract
This study investigates the hydrological connectivity between the Yogyakarta-Sleman Groundwater Basin (GWB) and the non-groundwater basin (non-GWB) area of Pajangan Hill using geochemical and isotopic methods. A total of 28 groundwater samples were analyzed for major ion content and isotopic composition, sampled from shallow wells, deep wells, and springs. Ion chromatography and cavity ring-down spectrometry were employed for analysis. The findings reveal that groundwater in Pajangan Hill predominantly consists of calcium bicarbonate, while Yogyakarta-Sleman GWB includes calcium bicarbonate, calcium nitrate, and sodium bicarbonate. Isotopic analysis indicates that water samples close to the Local Meteoric Water Line (LMWL) likely originate from local rainwater infiltration, maintaining their original isotopic composition. Despite some geochemical similarities, based on classification and composition analysis, significant differences in major ion concentration values suggest no hydrogeological connection between the two regions. The distinct lithologies, limestone in Pajangan Hill, and young volcanic deposits of Merapi in Yogyakarta-Sleman GWB further support this conclusion, indicating no hydrological connectivity between these areas.
