Abstract

The purpose of this study was to find out the diversity index of molluscs (gastropods & bivalves) based on mangrove degradation level in Tobea Island of Muna Regency. The data were collected from May until July 2017, in Wangkolabu municipal area of Tobea sub-district, using observation method and direct observation in the research location to find out the index of ecology of molluscs such as index of diversity (H'), evenness (E), density (N), dominance (D), and dispersion pattern (Id) from both gastropod and bivalve classes based on mangrove degradation level. Direct identification in the field is applied to the type of mangrove vegetation and mollusc organisms that have been known by it’s scientific name. But if not, then the samples are taken and the documentation is then done further analysis at the Laboratory of Biology Unit of Ecology and Taxonomy of FMIPA UHO with reference to the guide book of Introduction of Mangrove in Indonesia and book Snail & Shell Indonesian. Then for water environment parameters in the form of water and substrate samples are further analyzed at Biology Laboratory of UHO Forensic and Biomolecular Unit using Miller triangle fraction method and APHA standard method. Statistical analysis is done using Excel Stat to determine the major components affecting the ecological index of molluscs in degraded mangrove areas. The results showed four species mangroves in Wangkolabu Village are Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorrhiza, and Sonneratia alba and that mangrove degradation on the coast of Tobea Island, Wangkolabu village, Tobea sub-district has varied values for good mangrove criteria (Density/RDi = 1.600 individuals/hectare), medium mangrove (Density/RDi = 1.175 individuals/hectare), and mangrove broken/rare (Density/RDi = 375 individuals/hectare). Besides that, Cerithium spp., Nerita costata, Terebralia sulcata, and Clypeomorus sp., type gastropods is able to adapt to mangrove forests that have moderate density (RDi= 1.000–1.500 individuals/hectare), with mangrove substrate types in the form of sandy loam that has soil organic content (BO = 3,18%). While the gastropod type Telescopium telescopium prefers low density mangrove forests (RDi < 1.000 individuals/hectare) with the type of substrate in the form of clay containing organic matter (BO = 2,35%).  Based on the results of the study it is expected that the need for mangrove forest management in the study area for the sustainability of aquatic biota, especially molluscs that can be developed as conservation areas by looking at the level of mangrove damage through non-fish aquaculture activities (shellfish) for the welfare of coastal communities and islands small in Southeast Sulawesi.

Abstract

Kabuto is a traditional cassava-roots-based food of Munanese which is resulted from natural fermentation. The natural fermentation is conducted by covering all surfaces of cassava roots with fungal colonies. This experiment aims to study the cassava root fermentation by Aspergillus spp. in order to enhance the nutritive value, especially its impact on cyanide level. Both pure samples and replicated samples of cassava roots were fermented by Aspergillus spp. in a solid-state fermentation medium for six days and with a dryness level of ± 28°C. The products were analyzed to know the water content (%), the total amount of protein (mg), and cyanide detoxification (µg.g-1). Isolate K03, K23, K1c, and K31 were positively impeding activities of antimicrobials and hydrolytic enzymes (amylase and cellulase). The isolates, K03, K23, K1c, and K31 positively impeded the growth of Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 35218. Based on the phenotypic characteristics, the isolate K03, K23, dan K1c, had similarity with Aspergillus niger, while isolate K31 had a similar microscopic and macroscopical features of Aspergillus terreus. The water content of Kabuto decreased starting on the fourth day. The isolate K03, K23, K31, and K1C preserved the water content in kabuto at 7.1%, 6.74%, 8.69%, and 7.07% respectively. The highest protein content was observed from the fermentation by Aspergillus terreus K31 (346 mg) and was able to reduce the cyanide concentration until 0.48 µg.g-1. The optimum fermentation in the preparation of kabuto was achieved at sixth day.

Abstract

The increasing reliance on synthetic insecticides for pest management has raised concerns regarding environmental contamination, pest resistance, and adverse effects on non-target organisms. Consequently, the development of environmentally friendly alternatives such as botanical insecticides has gained considerable attention. This study aimed to evaluate the effectiveness of Cerbera odollam Gaertn. leaf extract against Thrips parvispinus Karny and to determine the lethal concentration required to kill 50% of the test population (LC₅₀) within 96 h of exposure. The experiment was conducted from August to October 2021 at the Biology Laboratory and Greenhouse, Faculty of Mathematics and Natural Sciences, Halu Oleo University, Indonesia. A Completely Randomized Design (CRD) was employed consisting of four extract concentrations, namely 1.0%, 1.5%, 2.0%, and 2.5%, along with a positive control (Regent 50 SC) and a negative control (distilled water). The extract was applied by spraying onto cayenne pepper plants infested with T. parvispinus, and observations were carried out for seven consecutive days. Mortality percentage, mortality rate, and LC₅₀ values were evaluated. The results demonstrated that C. odollam leaf extract significantly increased thrips mortality. The highest efficacy was observed at a concentration of 2.5%, resulting in 100% mortality and a mortality rate of 0.55 individuals per 24 h, which was statistically comparable to the positive control treatment. Probit analysis revealed an LC₅₀ value of 2.07% after 96 h of exposure. These findings indicate that C. odollam leaf extract possesses considerable potential as an environmentally sustainable botanical insecticide for controlling T. parvispinus populations in cayenne pepper cultivation.

Abstract

Green Campus initiatives emphasize sustainable waste-management practices as an important component of institutional sustainability. Black Soldier Fly (BSF; Hermetia illucens) bioconversion has emerged as a promising approach for converting organic waste into value-added products while reducing environmental burdens. To support sustainability education and promote awareness of BSF-based organic waste management, BIOMAGIC (Bio-Maggot Innovative Guide for Green Integrated Campus) was developed as a digital flipbook integrating concepts of organic waste management, BSF bioconversion, and Green Campus implementation. This study aimed to evaluate the educational feasibility and user acceptance of BIOMAGIC among undergraduate biology students at Universitas Negeri Makassar (UNM). A developmental evaluation approach was conducted during a socialization activity held in June 2026. Data were collected using Google Forms through pre-test and post-test knowledge assessments and a perception questionnaire. A total of 35 participants completed the pre-test, whereas 21 participants completed the post-test and user evaluation questionnaire. Participants demonstrated high baseline knowledge regarding BSF-based organic waste management, with mean pre-test and post-test scores of 95.10% and 95.24%, respectively. Knowledge related to BSF biological characteristics and cultivation showed higher post-test percentages, whereas sustainability-related concepts exhibited comparatively lower scores. User evaluation indicated favorable responses toward BIOMAGIC, with an overall mean perception score of 4.46 on a five-point Likert scale. Visual design received the highest ratings, while qualitative feedback highlighted accessibility, systematic content organization, and support for independent learning as major strengths. The findings support BIOMAGIC as a feasible and well-accepted digital learning resource for promoting awareness of BSF-based organic waste management and Green Campus concepts among university students.

Abstract

Indonesia's coastline is home to various complex ecosystems, such as mangroves, coral reefs, and seagrass beds. These ecosystems are very important in maintaining marine biodiversity and supporting the economic activities of local communities. One of the main problems that conservation efforts for coastal ecosystems face is the low level of environmental knowledge and awareness among local communities, especially among the younger generation. This activity aims to give students an understanding of how important marine ecosystems are through a participatory educational approach while simultaneously raising awareness about how human behavior impacts the sustainability of coastal resources. The results of this activity showed an increase in student understanding as evidenced by their ability to re-explain the concepts of mangrove, seagrass, and coral reef ecosystems their ecological functions and threats plus their ability to provide concrete examples on the role of coastal ecosystems in maintaining environmental stability. In terms of awareness regarding ecological threats students can mention various damage factors like pollution mangrove logging and uncontrolled tourism activities.

Abstract. Hasidu LOAF, Jamili, Kharisma GN, Prasetya A, Maharani, Riska, Rudia LOAP, Ibrahim AF, Mubarak AA, Muhasafaat LO, Anzani L. 2020. Diversity of mollusks (bivalves and gastropods) in degraded mangrove ecosystems of Kolaka District, Southeast Sulawesi, Indonesia. Biodiversitas 21: 5884-5892. Mollusks are one of the mangrove organisms whose classes are bivalves and gastropods. It plays an important role in mangrove and marine ecosystems as filter feeders, predators, and herbivores. This study aims to knows the diversity and abundance of mollusks (bivalves and gastropods) in several mangrove ecosystems in the Kolaka coastline as well as the similarity of these locations. This study was conducted in mangrove ecosystems of Induha Village, Mangolo Village, Tahoa Village, and Towua Village of Kolaka District, Southeast Sulawesi, Indonesia, from July to August 2019. This is a transect method stretched along a 100 m line perpendicularly from the seaward. The size of the mollusks subplot was 1 m2 and placed along the line transect. Each line transect comprises 10 subplots. To analyze the diversity index, evenness index, and its abundance, Kaleida Graph 4.0 version was used. This research indicates that the mollusks consist of 4 families of bivalves with 6 species and 10 families of gastropods with 182 species. It also found out 23 species of mollusks scattered to each location. The molluscan species which spread in all four mangrove ecosystems were Terebralia sulcata, Nerita planospira, and Batillaria multiformis. In Induha, the mollusks species were Anadara notabilis and Drupella margariticola. Meanwhile, Saccostrea cucullata, Pirenella incisa, Clithon oualaniensis, and Clithon pulchellum were only found in Towua. The diversity index of bivalves in each location was categorized as low diversity index category, as well as gastropods were categorized as medium diversity index. The highest diversity index of gastropods was in Induha (H' = 1.96). It was supported by the good mangrove ecosystem for mollusks' habitat. The lowest diversity index of gastropods was in Towua (1.41). This research depicts that three kinds of species with high abundance rate whose rates were &gt;1 ind/m2are located in two different locations namely; P. incisa (3.9 ind/m2) and S. cucullata (3.2 ind/m2) in Towua and followed by B. multiformis (2 ind/m2) and Isognomon ephippium (1.2 ind/m2) in Mangolo.

Abstract

Penelitian ini bertujuan menganalisis strategi adaptasi mata pencaharian nelayan Bajo dalam mempertahankan ketahanan sosial komunitas di tengah ekspansi pertambangan nikel di Pulau Wawonii. Penelitian dilakukan di Desa Langara Bajo, Kecamatan Wawonii Barat, Kabupaten Konawe Kepulauan. Penelitian ini menggunakan pendekatan mixed-method dengan dominasi kualitatif dan dukungan data kuantitatif deskriptif. Informan penelitian berjumlah 10 orang yang dipilih secara purposif, meliputi nelayan Bajo, perempuan dalam rumah tangga nelayan, aparat desa, tokoh masyarakat, serta pihak pemerintah daerah yang berkaitan dengan perikanan dan perencanaan pembangunan. Data kuantitatif diperoleh melalui survei terhadap 30 responden rumah tangga nelayan. Data dikumpulkan melalui wawancara mendalam, observasi, FGD, survei, dokumentasi, dan data sekunder, kemudian dianalisis secara tematik dan deskriptif. Hasil penelitian menunjukkan bahwa ekspansi pertambangan nikel menghadirkan situasi ambivalen bagi nelayan Bajo karena membuka peluang pasar baru bagi hasil tangkapan, tetapi juga memunculkan ketidakpastian sosial-ekologis pada ruang pesisir. Nelayan Bajo mengembangkan strategi adaptasi melalui penyesuaian musim dan wilayah tangkap, perluasan pemasaran, keterlibatan perempuan, diversifikasi pekerjaan, serta dukungan kelembagaan. Kebaruan penelitian ini terletak pada penjelasan bahwa strategi adaptasi mata pencaharian tidak hanya berfungsi mempertahankan ekonomi rumah tangga, tetapi juga membangun ketahanan sosial komunitas. Dengan demikian, artikel ini memperluas kajian sustainable livelihood dan social resilience dalam konteks ekspansi industri ekstraktif di pulau kecil.
