Implications of shorter sampling durations on the analysis of municipal solid waste generation and composition

Collecting samples of waste generation is essential for designing effective waste management strategies. Conducting waste generation sampling over a week or an 8-day period needs substantial demands on resources. The resource-intensive nature of extended sampling periods is notable. Shortening sampling days is beneficial and perhaps can also be cost effective. Cost-effective means reducing resource demands while maintaining the accuracy and reliability of waste generation data. The solid waste generation sampling data from two sub-districts both in Banyuwangi Regency and in Jembrana Regency, Indonesia were used for data source. Normality test and ANOVA (analysis of variance), followed by Tukey's post hoc analysis was utilized to analyze the variability among sampling duration, weekdays and weekend, and seasonal change. The generation of household wastes appears consistent in patterns over 4 or 8 days, irrespective of the sampling days falling on weekdays or weekends. When comparing the rainy and dry seasons, it was observed that only one sub-district in Muncar exhibited a statistically significant difference in waste generation. The remaining locations demonstrate no substantial statistical variation between the two seasons. This suggests a level of uniformity in waste generation across different time periods and seasonal condition, with Muncar being the sole exception.
