Abstract

Food waste is critical issue in developing countries, including Indonesia, affecting both the retail and consumers. In the case of vegetables, food waste frequently arises due to their short shelf life, spoilage, and physical damage. Additionally, the instability of vegetable prices creates challenges for consumers in meeting their needs. In sufficiency in the vegetable supply chain exacerbate the problem leading to leftovers and waste. This research aims to explore the causes of vegetable food and propose effective procurement strategies to mitigate it. A quantitative research approach was employed, with data collected through structured interviews involving 127 vegetable traders. The analysis utilized ANOVA to examine the effect of traders’ demographic characteristics on factors contributing to food waste. The results showed that demographics factors, such as age, daily turnover, and market location, significantly influence procurement strategies. Key findings underscore the importance of proper packaging tailored to the specific type of vegetable and the need for supplier intervention, to ensure adequate packaging during delivery, thereby maintaining vegetable quality. Moreover, traders with higher turnover rates are advised to carefully manage their purchasing practices to minimize waste. These insights highlight the critical role of procurement strategies in reducing vegetable food waste and the need for targeted interventions across the supply chain.

Abstract

Good production planning can meet the demand and availability of raw materials, as well as proper production planning and scheduling, production control, inventory control, and evaluation. PDAM XYZ produces clean water for the Banyumas Regency area. Water demand at PDAM XYZ is starting to exceed the production capacity limit, so a capacity addition plan is needed to meet the customer's clean water demand. The addition of capacity can be calculated by calculating demand forecasting. Thus, this study aims to determine the best forecasting method for making water demand forecasting calculations at PDAM XYZ and the estimated amount of water demand at PDAM XYZ in the next five years. The forecasting methods used are least square and regression. The accuracy values compared are MAD, MSE, RMSE, MAPE, and Tracking signal. The results of the comparison state that the regression method is better with a MAD value of 129938.4, MSE of 28536740000, RMSE of 168928.2, and MAPE of 0.05. So, in planning the addition of production capacity, the regression method can be used to forecast calculations as a reference for determining the additional production capacity. The forecasting results using the regression method show a value of 4,352,051 m3. Based on these results, it is expected that PDAM XYZ will be able to map the amount of clean water demand so that customer water needs can be met.

Abstract

Banyumas values are ancient traditions, and cultures are slowly considered old-fashioned and outdated. It creates a reluctance to implement, continue, and believe in them. The value is almost similar to Javanese values, but it has some differences. The value shall be maintained to mitigate food waste in this era. The National Waste Management Information System (SIPSN) of the Ministry of Environment and Forestry (KLHK) mentioned that total food waste reached 74.11% In Banyumas, and young consumers dominate the proportion of Indonesia's demographics. This research aims to find the relationship between Banyumas values, home edutainment, household routine, and anti-food waste lifestyle from young consumers. The method used was quantitative, and the statistical approach used the SEM-PLS (Structural Equation Modeling - Partial Least Square) with 409 respondents. The results showed that Banyumas values, home edutainment, and household routines significantly influence an anti-food waste lifestyle. To maintain the anti-food waste lifestyle of the young consumer in Banyumas, it needs education from their family by conducting food literacy. Young consumers shall be guided to preserve their food and avoid waste whenever they stay. Furthermore, the responsibility of each young consumer shall be maintained and revisit the cultural aspects of Banyumas as a society that upholds the local wisdom.

Abstract

Dairy farming in Indonesia is now experiencing significant development. In the milk supply chain, the increase in the use of milk as a raw material makes the milk processing industry increase its supply by 10% annually. However, milk production in Indonesia can only meet around 22% of the total. It means a gap of around 78% shall be imported. The imbalance between the demand and production causes Indonesia to lack self-sufficiency. Banyumas still have traditional methods, such as milking and filtering fresh milk. Such circumstances are prone to food loss, which needs preventive action to improve an effective and efficient supply chain by emphasizing information exchange in the milk supply chain. The study aims to determine how information exchange affects food loss in the milk supply chain in Banyumas. The study used quantitative and Chi-Square to conduct statistical analysis of 46 farmers. The result showed that demographics correlate with information exchange. Furthermore, farmers should improve their knowledge about the loss in the milk supply chain. They shall improve their understanding to adopt information technology to gain accurate and up-to-date data regarding milk production. Those activities are related to preventing food loss. Therefore, stakeholders' roles, such as farmer groups and cooperatives, are significant in facilitating the activities.

Abstract

Water-use efficiency is a strategic issue in large-scale coal-fired steam power plants, given the high operational water demand and the increasing need to implement the Zero Liquid Discharge (ZLD) concept. However, most previous studies have examined the performance of desalination systems, cooling processes, or wastewater treatment installations separately, thus failing to provide a comprehensive picture of water loss and Zero Liquid Discharge (ZLD) readiness at the system level. This study adopts an integrated operational water balance approach to analyse water-use efficiency, trace the main pathways of water loss, and evaluate the extent of Zero Liquid Discharge (ZLD) achieved at a 1×1000 MW coal-fired power plant (PT XYZ). A quantitative case study was conducted using four years of operational data (2019–2022) on seawater inflow, Reverse Osmosis (RO) performance, internal water-use patterns, and Wastewater Treatment Plant (WWTP) efficiency. The analysis results show that total water loss exceeded 60% of the annual volume of seawater taken, while the Reverse Osmosis (RO) recovery rate was low, at 6.07–6.19% during 2019–2021, before increasing to 11.85% in 2022. This condition indicates a significant gap between the system's actual performance and the Zero Liquid Discharge (ZLD) target. On the other hand, although the Wastewater Treatment Plant (WWTP) has consistently achieved pollutant removal efficiencies above 95%, its contribution to overall water recovery improvement remains relatively limited. These findings confirm that integrated water balance analysis can serve as an effective diagnostic tool for linking operational inefficiencies to Zero Liquid Discharge (ZLD) readiness levels and for providing lessons applicable to water management in power generation systems with high water-use intensity.
