Indonesia's quality of life index is the 8th lowest out of 19 countries in Asia. In Southeast Asia, the highest quality of life index is Singapore, Indonesia is ranked 3rd from countries in Southeast Asia. Based on an initial survey conducted on 20 male residents in Taratara Village, West Tomohon District, Tomohon City, there are 11 residents who have a poor quality of life. The purpose of the study was to determine the relationship between smoking and social support with the quality of life of men in Taratara Village, West Tomohon District, Tomohon City. This research method uses an analytical survey research method with a cross sectional approach. This research was conducted online using the Google Form platform in July-October 2020. The population in this study was male population aged 17 years, and the sample of this study was 60 samples obtained by simple random sampling technique. Data analysis includes univariate analysis and bivariate analysis using Chi-Square test with 95% confidence level (α = 0.05). The results of 60 respondents were 34 respondents had a good quality of life in the physical domain, 24 respondents had a good quality of life in the psychological domain, 45 respondents had a good quality of life in the social relations domain, 39 respondents had a good quality of life in the environmental domain. The conclusion of this study is that there is a relationship betweensmoking and quality of life in the domain of social relations (p = 0.02) and there is a relationship between social support and quality of life (p = 0.00) for men in Taratara Village, West Tomohon District, Tomohon City.Keywords: Smoking, Social Support, Quality of Lif

Fine-Scale in Situ Measurement of Riverbed Nitrate Production and Consumption in an Armored Permeable Riverbed

Alteration of the global nitrogen cycle by man has increased nitrogen loading in waterways considerably, often with harmful consequences for aquatic ecosystems. Dynamic redox conditions within riverbeds support a variety of nitrogen transformations, some of which can attenuate this burden. In reality, however, assessing the importance of processes besides perhaps denitrification is difficult, due to a sparseness of data, especially in situ, where sediment structure and hydrologic pathways are intact. Here we show in situ within a permeable riverbed, through injections of 15N-labeled substrates, that nitrate can be either consumed through denitrification or produced through nitrification, at a previously unresolved fine (centimeter) scale. Nitrification and denitrification occupy different niches in the riverbed, with denitrification occurring across a broad chemical gradient while nitrification is restricted to more oxic sediments. The narrow niche width for nitrification is in effect a break point, with the switch from activity “on” to activity “off” regulated by interactions between subsurface chemistry and hydrology. Although maxima for denitrification and nitrification occur at opposing ends of a chemical gradient, high potentials for both nitrate production and consumption can overlap when groundwater upwelling is strong
