The erosion rate is very light covering an area of 6,426.26 ha (71.28%) with natural forests, dryland agriculture, and paddy fields. The moderate erosion rate is 583.83 ha (6.48 %) on dryland and paddy fields farming. The severe erosion rate is 1,087.99 ha (12.07%) on land use in the form of dryland agriculture. The very severe erosion covering an area of 916.85 (10.17%) with the use of dryland agriculture.

The aim of the study was to determine the density, canopy cover, and organic carbon content in mangrove sediments. Data were collected from 3 stations, using transects measuring 10 x 10 m to determine density, height, trunk circumference, and canopy cover, as well as macrozoobenthos sampling. The mangrove density in Lembongan is very high, the tree height reaches 8 – 10 meters, and the mangrove canopy cover is in a good category. The macrozoobenthos diversity index is in the medium category and the carbon content in the sediments is high. Mangroves in Perancak Estuary are densely dense, with an average tree height of 8 meters, and canopy cover in the good category. The index of macrozoobenthos diversity was moderate and the organic carbon in the sediments was lower than in the mangroves at Nusa Lembongan. The character of the mangrove vegetation is different in the two areas. The Nusa Lembongan mangrove growing area is directly opposite the sea, but in the Perancak Estuary, it tends to be closed and flows by a large river around it. The mangrove growth zone is still natural in the Nusa Lembongan area, in contrast to the Perancak Estuary mangrove area which has been rehabilitated at several points. \u0000Keywords: Mangrove vegetation; macrozoobenthos; carbon on sediment","PeriodicalId":207732,"journal":{"name":"ECOTROPHIC : Jurnal Ilmu Lingkungan (Journal of Environmental Science)","volume":"21 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114006915","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}

Of the various forms of agricultural land use, paddy fields are land that has undergone many changes in designation so that the conversion of paddy fields occurs rapidly and massively. The total area of ??paddy fields that decreased in the 5 years from 2016 to 2020 was 1,193.54 hectares. Seeing this phenomenon, it is important to know how the status of rice fields in Tabanan Regency is sustainable using five dimensions, namely economy, ecology, social, technology and institutional.  The data were obtained through interviews with Pekaseh (kelihan subak) and farmers who carried out the conversion of paddy fields in nine subaks in nine sub-districts in Tabanan Regency, namely Pupuan, Penebel, Baturiti, Kediri, Tabanan, Kerambitan, Selemadeg, West Selemadeg, and East Selemadeg Districts. The analysis used is MDS (Multi Dimension Scaling) which is an adjustment of Rapfish using RSI TM Software (Rapid Sustainability Index) which was developed for the assessment of sustainability functions in general. The results showed that the multi-dimensional sustainability index obtained a value of 59.70 with a moderately sustainable sustainability status with the index value for each dimension being 74.56 for the ecological dimension with moderately sustainable status, 48.82 for the economic dimension with less sustainable status, 75.42 for the social dimension with sustainable status, 52.43 for the institutional dimension with moderately sustainable status and 47.25 for the technological dimension with less sustainable status. It is suggested that the local government of Tabanan Regency should to pay attention to the attributes that exist in the economic and technological dimensions so that it is expected to change its sustainability status to be quite sustainable, or sustainable and the attributes that exist in the ecological and institutional dimensions (sufficiently sustainable) can shift its status to continyu so that the value of the multi-dimensional index can increase. \u0000Keywords: conversion; paddy fields; sustainability status","PeriodicalId":207732,"journal":{"name":"ECOTROPHIC : Jurnal Ilmu Lingkungan (Journal of Environmental Science)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128452496","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}
