Hazardous and toxic waste are not only produced by industry, but also by households. But in fact, the household activities also produce Household Toxic and Hazardous Waste (HTHW). Considering the potential of the impact of HTHW to worsening environment quality, the effort of HTHW management must have been started well. One important aspect in the management strategy is to determine the characteristics and the HTHW generation. The method used to determine the characteristics HTHW refers to SNI 19–2454–2002, while the calculation of HTHW generation refers to the SNI 19–3694–1994 calculated based on weight and volume. Sampling was conducted in four districts of Semarang (Pedurungan, Semarang Barat, Semarang Utara and Banyumanik). The samples used in this study were 400 families that were selected based on the proportion of Slovin Formula. Data analysis performed using Analysis of Variance (ANOVA) and Kruskal-Walis test (α = 0.05). The largest characteristic of HTHW in Semarang City is infectious (79%), further Poisonous (13%), Combustible (6%) and Corrosive (2%). While HTHW generation is 0.01 kg/person/day (5.1% MSW). Statistical test result showed there was a significant difference (p-value : 0.001) between HTHW generation based on economic level, but there was no significant difference (p-value :0.442) between HTHW characteristics in Semarang city. The level of education, occupation, income level and lifestyle may become potential factors in differentiating the characteristics and HTHW generation in Semarang city.
