This study aimed to analyze the use of plants as medicinal ingredients for the indigenous Cabai community in Patikalain Village, Hantakan District, Hulu Sungai Tengah Regency, which is part of the Meratus Mountains Dayak tribe. The method of data collection was done by semi-structured interviews. Selected respondents were determined by purposive sampling and snowball sampling techniques. Data were analyzed by tabulation matrix. There were 18 types of forest plants that were used as medicine by the indigenous people of Cabai. The most widely used plant habitats for medicinal purposes were shrubs/shrubs and trees. Roots and leaves were the most widely used plant parts in medicine. There were at least 23 diseases that could be treated with various types of plants. Forest plants were widely used for internal medicine compared to external medicine. Treatment using plant ingredients was the first alternative used by the community in medicine. If this did not work, then community members who were sick would be directed to seek treatment at the Local Health Care Unit. If modern medicine did not work, the next alternative, then additional treatment using traditional rituals, was the last option. This finding was a contribution to knowledge in the traditional medicine system of the local community.","PeriodicalId":165554,"journal":{"name":"Proceedings Series on Physical & Formal Sciences","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115853997","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}

In order to evaluate the tolerance level and response of several local rice genotypes to submersion stress in the vegetative phase, 50 rice genotypes were screened (47 North Sumatran local varieties, 3 VUB), using special ponds to simulate flooding or inundation stress. The study used a separate plot design with three replications; the main plot was three immersion models, namely full immersion, partial soaking, and not soaking, and subplots of 50 rice genotypes. The immersion treatment was defined as a different growing environment. The results showed that in the fully submerged treatment, the recovery capacity of local rice plants only ranged from 0-20%. The new, improved varieties tested were Inpari 4 (susceptible), Inpari 3, 10, Ciherang, Inpara 2 (very susceptible), Inpari 30, FR13A (very tolerant). Submersion tolerant genotypes had a slight increase in plant height after being fully submerged. The chlorophyll content in the leaves decreased immediately after the soaking stress period (14 DAP) in all rice genotypes. The local rice genotypes tested were very susceptible to immersion; the new superior variety Inpari 4 was categorized as susceptible, while Inpari 30 and FR13A were very tolerant.","PeriodicalId":165554,"journal":{"name":"Proceedings Series on Physical & Formal Sciences","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132682803","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}

This study aimed to describe the effect of shading and type of variety on plantlet acclimatization of the Dorit variety and the local Berastagi variety. This research was experimental with RAK using 2 factors, namely shade with the plastic thickness of 0.17 mm and 0.12 mm and types of local varieties of Berastagi and Dorit varieties.
