Abstract. Massiseng ANA, Tuwo A, Fachry ME, Bahar A. 2022. Characteristics of plastic waste and perceptions of coastal communities in the MLC Baluno mangrove ecotourism area, West Sulawesi, Indonesia. Biodiversitas 23: 6262-6274. Plastic pollution is a global problem that threatens coastal and marine ecosystems and human livelihoods and requires effective solutions that can be adapted to local conditions. Management of coastal areas is one sector focusing on world development in general and Indonesia in particular. This research was conducted from July to October 2021 in the mangrove ecotourism area of ??MLC Baluno, Sendana Sub-district, Majene District, West Sulawesi Province, Indonesia. The type of data used is the primary data from measurements and observations at ecotourism sites. The purpose of this study was to identify the characteristics of plastic waste and analyze its impact on the socio-economic community in the MLC Baluno mangrove ecotourism area. The results showed (1) The percentage of plastic waste types from all observation stations in the MLC Baluno mangrove ecotourism area consisted of 22% HDPE, 20% LDPE, 17% PVC, 9% PETE, 12% PE, 10% PP, 6 % PE, and 4% PU, (2) The volume percentage of plastic waste from observation stations in the mangrove ecotourism area of ??MLC Baluno by type consists of 32% PVC plastic volume, 17% HDPE, 14% PE, 10% LDPE, 10% PETE, PP 11%, 4% PS and 2% PU, (3) The influence of plastic waste factors (types and volume) has a positive effect on the socio-economic community (livelihood and income). The variable factors of plastic waste influencing socio-economic based on the perceptions of coastal communities in the MLC Baluno mangrove ecotourism area are TW2, VW3, VW4, LV1, LV2, IC1, IC3, and IC5.

Biodiversity of hard coral (Scleractinia) and relation to environmental factors turbid waters in Spermonde Islands, South Sulawesi, Indonesia

“…The higher activities carried out in coastal areas, especially development, contribute to sediment in the waters, in addition to river flow. Enrichment of waters with nutrients (D'Angelo and Wiedenmann 2014) marine tourism and can also be caused by marine tourism (Abidin and Mohamed 2014;Cerutti-Pereyra et al 2022;Massiseng et al 2022), sedimentation (Lafratta et al 2017;Morgan et al 2020) and global warming (Pratchett et al 2013;Lafratta et al 2017;Morgan et al 2020) which has an impact on coral reef damage, so that the coral genera becomes reduced. Acropora coral species are found in all locations, as many as 17 individuals and in the waters of Samalona Island, this type is found a lot.…”

“…There are also biota that prey on corals (Mitchell and Harborne 2020) and also activities in coastal areas such as development, but certain types of corals can still adapt to the changes that occur. However, over-utilization makes changes to coral ecology (Bartley et al 2014) such as destructive fishing activities (El-Nagar 2021) and coastal development (Soares et al 2021;Mahatir et al 2022) or upland activities (nutrient and sediment inputs) influence the growth of macroalgae, thus inhibiting coral growth (D'Angelo and Wiedenmann 2014; Loiola et al 2019), tourist behavior (snorkeling and diving) stepping on or touching corals so that there are many coral fractures (Abidin and Mohamed 2014;Cerutti-Pereyra et al 2022;Massiseng et al 2022) and global warming is causing sea surface temperatures to rise, leading to coral bleaching (Pratchett et al 2013;Lafratta et al 2017;Morgan et al 2020). These factors directly or indirectly affect coral life in the water.…”

Tropical climate change and its impact on horticultural plants in Enrekang District, South Sulawesi, Indonesia

“…Rainfall varies every year, can change quickly and have different rainfall events even they are in almost the same place (Giarno et al 2018). Areas with high rainfall can affect the physicochemical properties of the soil (Ahmad et al 2018), causing a lot of waste to be carried away (Massiseng et al 2022) and also, if land use is not adjusted to the capacity of the land will cause landslides and affect the availability water for plants (Saida et al 2016). High rainfall intensity can be the leading cause of flooding (Ramadhan et al 2023).…”
