Based on its management, the Maninjau Nature Reserve is divided into protection blocks, rehabilitation blocks and special blocks. Meanwhile, Silayang-Malabur is included in the rehabilitation block where this block has suffered damage caused by illegal logging and conversion of forests into fields which have an impact on reducing carbon stocks. Therefore, it is necessary to conduct this research to determine stored carbon stocks. This research was conducted in the Maninjau Nature Reserve area, Silayang-Malabur Rehabilitation Block, Agam Regency, which was carried out from December 2022 - January 2023. This type of research was descriptive research by collecting data on plants in forest stands. Data collection used purposive random sampling which was divided into 2 research areas, namely natural forest and disturbed natural forest. The sample plots used were a single plot of 3 randomly distributed plots in each study area. Based on the results of research on carbon stocks in forest stands in the Maninjau Nature Reserve area of ​​Silayang-Malabur Rehabilitation Block, Agam Regency of 182,812 tons C/ha where carbon stocks in natural forest areas are 148,415 tons C/ha while carbon stocks in disturbed natural forest areas are 34,397 tons C/ha. According to the Ministry of Forestry's Bappenas criteria, it was concluded that the total carbon stock in the Maninjau CA area is in the high category.","PeriodicalId":110675,"journal":{"name":"Journal of Climate Change Society","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130199032","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}

{"title":"Characterization of Pig, Cow and Goat Raw Skin Using E-Nose for Visual Data Comparison of Characteristics of Halal Skin-Processed Products","authors":"Yogi Putra, Y. Darvina, Yulkifli","doi":"10.24036/jccs/vol1-iss1/8","DOIUrl":"https://doi.org/10.24036/jccs/vol1-iss1/8","url":null,"abstract":"The presence of questionable halal claims for various products in the market presents concerns among consumers, particularly Muslims. As a result, the need to accurately identify halal skin products has become crucial. This study focuses on differentiating pig skin from other commonly used raw materials such as cow skin and goat skin by utilizing visual characteristic data. The data was obtained through the analysis of samples using a chemometric-based electronic nose instrument, which detected volatile organic compounds (VOCs) through metal oxide semiconductor sensors (TGS 26xx and TGS8xx). The samples consisted of pig skin, cow skin, and goat skin, and their specific odors were measured and represented in line graphs, revealing distinct odor patterns detected by the sensors. The analysis revealed that pig skin exhibited the highest and increasing trend line, indicating a higher concentration of VOCs and an intense odor. Cow skin displayed a moderate trend line with lower concentrations of VOCs, while goat skin showed a lower trend line compared to cow skin but possessed strong odor properties. The analysis employed the linear discriminant analysis (LDA) method, which further confirmed these characteristics by generating line graphs that demonstrated significant differences, particularly in pig skin. The LDA plot graphs presented clear groupings of the original pig skin, cow skin, and goat skin data. Discriminant function 1 accounted for 89.13% of the grouping, while discriminant function 2 accounted for 10.87%, resulting in a total value of 100% for the discriminant function. In conclusion, this research establishes a clear distinction between pig skin and cow/goat skin based on their odor characteristics and sensor data. The LDA plot graphs serve as a valuable visual tool for identifying the characteristics of halal products. By utilizing this approach, consumers, especially those seeking halal-certified skin products, can make informed choices and have greater confidence in their purchasing decisions.","PeriodicalId":110675,"journal":{"name":"Journal of Climate Change Society","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126195786","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}

The tourism sector is one of the largest sectors and the main mainstay for the economy in various countries, including Indonesia. Countries that rely on the tourism sector must pay attention to several factors that attract tourists, one of which is climate comfort. Climate information is a major factor in choosing a tourist trip. This study aims to analyze the level of climate comfort in the coastal tourism area of Padang City using the Holiday Climate Index (HCI) method. HCI uses climate parameters such as air temperature, humidity, wind speed, rainfall, and cloud cover. HCI calculation data in the form of observation data obtained from the Meteorology Climatology Geophysics Agency (BMKG) station at Minangkabau International Airport and the Teluk Bayur Maritime Meteorology Station from 2011-2020, direct measurement data from August to September, and questionnaires. The results of the HCI analysis show that the city of Padang is comfortable throughout the year, with the HCI value in the range of 58.6-71.6 which is categorized as acceptable to very good. The results obtained through direct measurements also obtained comfortable results throughout the day with HCI values in the range of 70-80. Perceptions of tourists interviewed also stated that overall tourists felt comfortable with the percentage of respondents as much as 74.1%. HCI can be used as a source of information to determine the value of climate comfort in tourist areas.","PeriodicalId":110675,"journal":{"name":"Journal of Climate Change Society","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121912291","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}

PET calculation data is sourced from the Meteorology, Climatology and Geophysics Agency (BMKG) in 2011-2020 and direct measurement data. The results show that the PET thermal sensation category for the Padang City coastal area throughout the year (2011-2020) is included in the \"warm\" category for tourism activities. Likewise, direct measurements show the \"very hot\" category with a PET value of 40.3ºC. However, interviews with visitors showed that the overall comfort condition was “neutral” (62%). This is due to environmental conditions that provide a comfortable effect on visitors. The majority of visitors were interviewed under the auspices. Although the measured air temperature is classified as \"high\", the effects of trees, walking paths and rest areas make visitors feel comfortable.","PeriodicalId":110675,"journal":{"name":"Journal of Climate Change Society","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132697882","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}
