Abstract

Perintis lake is a significant aquatic area with considerable potential as a habitat for various bird species, as it is surrounded by forest and agricultural areas that support a diverse avifauna. This research aimed to determine the diversity and conservation status of waterbird species in the perintis lake area. The research employed survery method by determining observations stations and  following the water flow river transect along the lake using a boat while recording all birds seen or heard. The results identified several waterbird species, including the Collared Kingfisher (Todiramphus chloris), Purple Heron (Ardea purpurea), Black-crowned Night Heron (Nycticorax nycticorax), Cerulean Kingfisher (Alcedo coerulescens), White-browed Crake (Porzana cinerea), Javan Pond Heron (Butorides striata javanica), Barred Rail (Gallirallus torquatus) and Javan Pond Heron (Ardeola speciosa). The conclusions are as follows : (1) The waterbird diversity index (H’) at perintis lake ranged from 1.365 to 1.912, which falls into the moderate category, indicating that the waterbird community in thus lake is fairly diverse; (2) The evennes index (E) ranged from 0.378 to 0.526, indicating that the distribution of individuals among species is relatively stable

Abstract

The maleo bird (Macrocephalon maleo) is an endemic species of Sulawesi that holds both ecological and symbolic value for local communities. The distribution of the maleo is not only determined by ecological factors such as habitat availability, environmental suitability for nesting, climate change, and predator threats, but is also closely related to the socio-cultural dynamics of the surrounding communities. This article discusses the socio-cultural meaning of the maleo distribution map with an emphasis on a community-based conservation perspective. Through geospatial data and the exploration of local wisdom practices, it is evident that maleo distribution areas often intersect with the social spaces of indigenous communities, settlements, and symbols of collective identity. The presence of the maleo is regarded as part of cultural heritage passed down through generations, giving rise to traditional protection practices, such as restrictions on excessive egg collection or the designation of customary areas as conservation zones. The community-based perspective shows that conservation is not only focused on species preservation but also on strengthening the role of local communities as key actors. By integrating ecological distribution and socio-cultural values, maleo conservation efforts are expected to be more effective, adaptive, and sustainable. This article emphasizes that the success of maleo conservation largely depends on the recognition of the cultural values attached to its distribution as well as the active participation of communities in Sulawesi.

Abstract

The purpose of this study was to determine the types of phytoplankton in Perintis Lake, Suwawa District, Bone Bolango Regency, Gorontalo Province. This research is descriptive qualitative using survey method with phytoplankton as research subject. The data collection technique was carried out by purposive sampling which was carried out 3 times with the aim of collecting data effectively. The research procedure includes observation, measurement of water physico-chemical parameters, phytoplankton water sampling, and identification in the laboratory. Data analysis was carried out descriptively by identifying the types of phytoplankton using a binocular microscope and matched to the identification book. The results of the research obtained found phytoplankton 8 divisions with 24 species (Synura sp., Pandorina morum, Ankistrodesmus densus, Tetraedron triangulare, Selenastrum bibraianum, Scenedesmus sp., Tetrabaena socialis, Dictysphaerium ehrenbergianum, Raphidiopsis raciborskii, Snowella lacustris, Merismopedia sp...), Aphanocapsa sp., Pinnularia sp., Cyclotella polymorpha, Synedra sp., Pseudostaurastrum lobulatum, Isthmochloron lobulatum, Goniochloris sp., Penium polymorphum, Staurastum gracile, Aulacoseira granulata, Cochlodinium polykrikoides, Ostreopsis sp., and Prorocentrum minimum).

Abstract

Gurita adalah salah satu hewan laut yang penting karena kandungan gizinya yang tinggi dan harganya yang cukup mahal, serta memainkan peran penting di antara hewan laut lainnya. Penelitian tentang pola penyebaran gurita di lakukan di Desa Torosiaje Kecamatan Popayato Kabupaten Pohuwato pada bulan Februari 2024. Tujuan dalam penelitian ini untuk menganalisis pola penyebaran gurita (Octopus sp) di area penangkapan Perairan Torosiaje. Metode yang digunakan adalah metode purposive sampling, dengan memilih 6 area penangkapan yang sudah ditentukan sebagai titik pengamatan yakni area penangkapan I di Pulau Torosiaje Besar, area penangkapan II di Pulau Torosiaje Kecil, area penangkapan III Reef Lana Besar Batuna, area penangkapan IV di Reef Sapa Karanganan, area penangkapan V Reef Sapa Dua Bunginan Darat dan area penangkapan VI Reef Sapa Dua Bunginan Laut. Teknik pengambilan sampel dilakukan menggunakan alat tangkap khusus gurita, serta prosedur penelitian meliputi observasi, pengambilan sampel di lokasi penelitian, identifikasi melalui literatur ilmiah buku dan jurnal serta wawancara informal bersama nelayan lokal. Analisis data menggunakan perhitungan Indeks dispersi morisita (Id), perhitungan keseragaman (Mu) dan pengelompokan (Mc) dan perhitungan standar derajat morisita (Ip). Hasil penelitian yang diperoleh yakni hanya terdapat satu spesies individu gurita yaitu Octopus cyanea, dengan hasil analisis data memperoleh nilai indeks dispersi morisita pada titik pengamatan I yakni Ip = 0,3922, titik pengamatan II Ip = 0,42, titik pengamatan III Ip=0,4, titik pengamatan IV Ip=0,42, titik pengamatan V Ip = 0,3473, dan titik pengamatan VI Ip = 0,3573. Hasil yang diperoleh menunjukkan bahwa pola penyebaran gurita (Octopus cyanea) di area penangkapan Perairan Torosiaje adalah acak.

Abstract

Macrozoobenthos is an animal species that lives on the bottom of the waters and has various roles in the ecosystem, such as its role as a biological indicator that reacts to the condition of water quality so that its existence can be used as an indicator of water quality. This study aims to determine the diversity and abundance of macrozoobenthos in the mangrove ecosystem of Persatuan Village, Pohuwato Regency. This type of research is quantitative descriptive, the data collection method uses a survey method and the determination of observation stations uses a purposive sampling technique. Sampling was carried out at 2 stations, namely station 1 muddy substrate type and station 2 sandy mud. Based on the Macrozoobenthos data obtained in the mangrove ecosystem of Persatuan Village, there are 22 species consisting of 15 families and 22 genera with a total of 5,363 individuals. The diversity of Macrozoobenthos at station 1 obtained a value of H '= 2.42 and station 2 with a value of H '= 1.51. The abundance at stations 1 and 2 has a high category. The high value of the Abundance index at station 1 and station 2 indicates the presence of a dominant species, namely the Telescopium mauritsi species. The Telescopium mauritsi species has the highest abundance at each station with an index value of Di = 0.311.

Abstract

This study aims to determine the diversity and abundance of kingfisher species in the Marisa watershed, Karangetang Village. The method employed was Point Count, which involved 5 counting points, each 200 meters apart, with a viewing distance of 50 meters and observation time of 20 minutes. The study identified 4 kingfisher species from the Alcedinidae family, two of which are endemic (Ceyx fallax, Pelargopsis melanorhyncha) and two non-endemic (Alcedo meninting, Todirhamphus chloris) in the forest edge area point count 1,2 with diversity index H' = 3,00 (high) and point count  3, 4 and 5 community farmland area with diversity index H' = 3,26 (high). Among the four species, the most dominant was C. fallax (Di = 38,77%), T. chloris (Di = 36,73%), Alcedo meninting (Di = 22,45%), and Pelargopsis melanorhyncha (Di = 2,04%), indicating a moderate dominance in abundance.
