Abstract

The Kuala Langsa Mangrove Forest Area is a mangrove ecosystem in Langsa City that has been designated as an ecotourism area. The conversion of the Kuala Langsa mangrove forest area into an ecotourism area is suspected to cause changes in fish habitat, thus affecting fish populations. Research on fish species inventory in the mangrove forest ecotourism area is very relevant to understand the negative impacts of ecotourism on fish and the surrounding environment. An inventory of fish species in the Kuala Langsa Mangrove Forest Ecotourism Area was conducted from February to August 2024. This study aims to determine the species of fish found in the Kuala Langsa Mangrove Forest Ecotourism Area. The method used was an exploratory survey, by exploring the Kuala Langsa Mangrove Forest Ecotourism Area. The search started from the observation tower area to the river mouth. Sampling points were adjusted to environmental conditions, namely depth and habitat conditions. Sample collection was carried out using gill nets and nets, with 9 gill net installation points and 18 net throwing points. Sampling was carried out three times at each location. The research results obtained 90 individuals, consisting of 16 families and 18 species. The species with the largest number of individuals was found in the Gerres erythrourus (kapas) species with 12 individuals, followed by the Hyporhamphus balinensis (julung) species with 11 individuals, and the Sillago sihama (rejung) species with 9 individuals. The least number of species was found in the Caranx ignobilis (rambeu), Platycephalus indicus (baji-baji) and Lactoria cornuta (helicopter) species with one individual each.

Abstract

This study aims to estimate the population density, abundance, and sex ratio of rhinoceros beetles (Oryctes rhinoceros L.) at different growth phases of oil palm in PTPN I plantations, Langsa Baro District. This study was conducted from June to November 2023. The method used was an experimental method. Traps were installed in four sampling blocks, each covering an area of ​​20 Ha, namely immature plants (TBM), sand fruit phase (BP), productive plants aged 4-8 years (TM 4-8) and productive plants aged >10 years (TM >10). A total of eight trap units per plant growth phase were installed systematically with a distance between traps of 400 m. The results of the study obtained 100 individuals of rhinoceros beetles in all growth phases. The average population density was 1.25 individuals/Ha and abundance was 3,125 individuals/trap. Consistent pest management carried out in PTPN I oil palm plantations is suspected to affect the results obtained. The abundance of rhinoceros beetles trapped in the BP phase was the highest (4 individuals/trap) and was significantly different from the TM (4-8) and TM (>10) phases. There were more female rhinoceros beetle imagos trapped than male imagos, with a male:female sex ratio of 1:1.64. Future studies are needed to compare this with community-owned oil palm plantations, especially regarding the population and level of rhinoceros beetle infestation.

Abstract

Putroe Phang City Forest is one of the green open spaces in the Banda Aceh City area. City forests play a role in improving and maintaining microclimate, aesthetic value, absorbing water, maintaining environmental balance and harmony, and supporting biodiversity. The existence of trees in city forests can improve environmental quality. These efforts can be realized well if the city forest has a high diversity of tree species. This study aims to analyze the diversity of tree species in the Potroe Phang City Forest. Data collection was carried out using the census method by observing all plants with tree habits found in the research location. The parameters observed were the type of tree and the number of individuals from each tree. Data analysis was carried out by calculating diversity using the Shannon-Wienner diversity index equation. The results of the study obtained 31 species from 16 families with a total of 263 individuals. The family with the most species obtained was the Fabaceae family with five species, namely Laucaena leucocephala, Pithecellobium dulce, Pterocarpus indicus, Samanea saman, and Tamarindus indica. This species is a species that has been used as a protective plant. While the highest species obtained is Mimusops elengi or tanjung flower from the Sapotaceae family with a total of 82 individuals. The value of the tree diversity index obtained is 2.609 which is included in the moderate category.
