One of the causes of climate change is the existence of Green House Gases (GHG), especially carbon dioxide (CO2), which has the highest concentration in the atmosphere due to human activities. Massive development activities have caused the dynamics of changes in land use from undeveloped land to built-up land. Singkawang City Singkawang City has a population that continues to increase, namely in the period 2010-2020 it has a population growth rate of 2.27%. This of course can trigger a conflict of space requirements that are not proportional to the availability of existing land. Planning Area (WP) III of Singkawang City, which currently has a higher proportion of undeveloped land than built-up land, will faced challenges, due to the many development plans such as airports, industrial allotment areas and other supporting facilities. Of course, this will triggered changes in land use functions which can reduce carbon stocks. Therefore, the purpose of this study is to compare carbon stocks based on existing land use classes and the area of each type of money polar plan according to the Detailed Spatial Plan (RDTR) of WP III. The analytical method used is to analyze carbon stocks using conversions from the 2012 Directorate General of Forestry Planning standards and using the GHG calculator developed by ICLEI-Local Governments for Sustainability. The result of this study is that there is a decrease in carbon stocks in the spatial pattern plan (233.267,15 tons C) compared to carbon stocks based on the existing land use class in WP III (236.224,78 tons C). This shows that there is a difference of 2.957,63 tonnes C or a decrease in carbon stocks of 1,3%.","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133228057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use a survey method by conducting field observation with the community of Meureudu City as our sample, which amounted to 110 respondents. Our study showed that female housewife is the main gender in household waste management. Factors of the age group of 31-40 years (35%), bachelor and diploma education level (42%), high income, and family member > 4 persons (28%) are affecting the WTP. We also managed to gather information on the average waste of Meureudu City which amounted to 1,5 kg/person/day, exceeding the Ministerial Law of Environmental and Forestry (0,7 kg/person/day).

Compost is one of the nutrients that is often used in the manufacture of planting media on land in the form of polybags, and the amount of compost composition on the soil is thought to greatly affect the ability to store water in the media. This study aims to test drip irrigation on a mixture of compost and soil on storage of irrigation water. Tests were carried out at a ratio of 70%: 30%, 50%: 50% and 30%: 70%. Irrigation was tested at a duration of 5 minutes, 10 minutes, and 15 minutes, and the data analyzed included irrigation distribution data, discharge, soil moisture data (w) and daily soil moisture change data. The results of the analysis are presented in the form of tables and graphs, then discussed and concluded descriptively. The results of the analysis show that the flow rate obtained is greater if the difference in water level to the land is greater, and the average Cu value obtained is 95.79% which is very good. With initial soil moisture in the range of 19%-25, soil moisture gain obtained by drip irrigation for 5 minutes -10 minutes is around 12%, and for a duration of 15 minutes soil moisture gain is obtained by 8% -21%.

Utilization of forest areas as ecotourism objects is estimated to be able to contribute to the socio-economic community, especially in Wakatobi Regency which is included in the National Tourism Strategic Area. This study aims to analyze the suitability of the Peo Waume Forest Area to be used as an eco-tourism area and to analyze its sustainability index by taking into account the ecological, socio-economic, and institutional dimensions.
