Abstract

Ferns (Pteridophyta) are spore-forming cormophytes that can live in a variety of habitats both as epiphytes, terrestrial and aquatic. In the forest area of Noongan Village, many potentials play an important role in developing forest ecosystems. One such potential is ferns. The results of the study were eight types of ferns in the forest area of Noongan village which were divided into two plots of 50x50 meters at different heights, namely plot I at an altitude of 610 masl with a total of 380 ferns with the percentage: Paku Garuda (Pteridium aquilinium) 0.20 %, Elephant fern (Angiopetris avecta Hoofm) 0.01%, Red rane fern (Selaginella australis) 0.01%, Paku Kikir (Stenosomia Sp.) 0.14%, Ferret fern (Nephrolepis biserrataSchott.) 0, 21%, cecerenean fern (Nephrolepis falcata) 0.16%, suplir fern (Adiantum.) 0.12%, andam fern (Dicranopetris linearis) 0.12%. And plot II at an altitude of 869 meters above sea level with a total of 179 ferns with a percentage of: Garuda fern (Pteridium aquilinium) 0.21%, elephant fern (Angiopetris avectaHoofm) 0.01%, miserly fern (Stenosomia Sp.) 0, 17%, Paku harupat (Nephrolepis biserrate Schott.) 0.21%, Paku cecerenean (Nephrolepis falcata) 0.15%, Suplir (Adiantum.) 0.10%, Paku andam (Dicranopetris linearis) 0.12%. In the plot I, the types and number of ferns were higher than the types and numbers of ferns in plot II. No red fern (Selaginella australis) was found in plot II. And the plant species Paku Harupat (Nephrolepis biserrata Schott). The red fern has the highest number, and the red fern (Selaginella australis.) has the least amount. The difference in altitude greatly affects the surrounding environment. So that these differences greatly affect the number of types and numbers of ferns

Abstract

Chili plants are an important horticultural crop for the Indonesian population. Still, in the context of pest control, the use of insecticides to manage the OPT is proving to be increasingly problematic for the environment and human health as a result of their ability to decimate microscopic organisms present in the soil so that as decomposers or decomposer microorganisms and earthworms perish, the soil would ultimately become more barren. Therefore, it needs to be overcome by finding other alternatives that are more environmentally friendly and reduce the negative impact of pesticides. This study aimed to determine an environmentally friendly alternative biological control using the Beauveria bassiana fungus. This study used an experimental method with five treatments and three replicates, notably spore concentration using B. bassiana 6g, 7g, 8g, 9g, and control. The use of this fungus is simple and does not incur significant costs. From the results of data collection, the Beauveria bassiana fungus is effective in killing carambolae with a fast mortality rate at a concentration of 9 g/500 ml of water (86.7%), and the slowest concentration is at 6 g/500 ml of water (63.4%).

Abstract

Apis Dorsata Binghami is a honey bee that is often found in the forest, which is conserved by the community, but there are also honey bees that are just left alone; the community preserves these honey bees because their honey can be traded and can also be used as medicine. This study aims to determine the plants that are a feed source for Apis Dorsata Binghami in the Pinabetengan Forest, Minahasa Regency. This research was conducted in June-August 2022. The data collected came from field survey data using descriptive methods and identified plant species with values of Reactive Density (KR), Relative Frequency (FR), Relative Dominance (DR), and Index Significant Value (INP). Plant diversity as a food source for Apis Dorsata Binghami has different types of plants based on their habitus or the characteristics of the plants themselves.

Abstract

Tamba Beach has several ecosystems, namely seagrass beds, sandy and rocky. Ecologically, seagrass beds are home to marine life, including Echinodermata. Echinoderms play an important role as an integral part of the food chain, eating organic waste. The purpose of this study was to analyze the community structure of Echinoderms at Station I (Seagrass Zone), Station II (Sandy Zone) and Station III (Coral Zone). Two methods are used in this study. The first is a qualitative description method by directly observing and quantitatively calculating the diversity index, uniformity index, dominance and abundance index formulas. The echinoderms found consisted of 4 classes, namely Holothuidea, Ophiuroidea, Echinoidea and class Asteroidea. The echinoderms found at the study site used a diversity index classified as stable. The dominance index is low because there are no dominant individuals, and the uniformity index is low. From the results obtained from the abundance in Tamba Beach, the highest value was in the Diadema setosum species with 113 individuals. Diadema setosum has the highest quantity at the three existing stations. This species can adapt to environmental changes.

Abstract

Partial of the cytochrome C oxidase unit I (COI) mtDNA genes of the red jungle fowl (Gallus sp.) were isolated and sequenced to examine the base substitution pattern compared to several accessions taken from GenBank. Samples were collected from several areas in North Sulawesi in the form of muscle tissue and prepared with 95% alcohol, and stored at temperatures below 500 C. Total DNA was isolated using the innuPREP DNA micro kit with a modified protocol. The target gene amplification used the primers BirdR1 and BirdF1, and the amplicons were sequenced at the Singapore FirstBase laboratory. Target gene sequences have been blasted through the nucleotide blast program provided by the National Center for Biotechnology Information (NCBI)—sequence analysis using MEGA5 and DnaSPv5 software. Target gene sequences were aligned using the Clustal-W program on MEGA5. The amplified target gene sequence length was 490 bp. The blast results showed that the target gene sequence was 98% identical to the COI gene sequence from several Gallus-gallus accessions from GenBank. The results of multiple alignments between the sequences of some of the genes examined showed the presence of polymorphic sites (S). The number of polymorphic sites (S) is 11, while the conserved sequence (C) is 386/397 = 0.977. The number of haplotypes (h) is 5, and the diversity of haplotypes (Hd) is 0.703. The overall genetic distance average was 0.008. The polymorphic sites and base substitution events occurred at sites number 145 (A↔G), 241 (G↔C), 268 (C↔A), 295 (C↔A), 348 (T↔C), 381(A) ↔T), 384 (T↔C), 390 (T↔A), 393 (C↔T), 394 (T↔C) and 395 (C↔T). The substitution pattern at these polymorphic sites consists of substitution transitions and transversions. The ratio of transition substitution and transversion events (Ts/Tv) = 1.4056. The substitution events at these sites are located at the bases in the first and third positions of the codon. Substitution events at these polymorphic sites partially cause the exchange of amino acids. The exchange of amino acids occurs at codons 49, 81, 90, 99 and 130.

Abstract

One component of integrated pest control is biological control or biological control based on the bioecology of the pest by taking into account the results obtained and their long-term effects through ecology and economy. The success of controlling a type of pest requires studies on various factors that affect the life of a pest, namely biology, morphology, ecology, genetics, and evolution. Knowledge of the biology of a pest species will provide appropriate information in breaking the life cycle or making the surrounding environment not provide optimal carrying capacity so that the pest population can be suppressed below the economic threshold. Spodoptera exigua is a polyphagous insect pest that eats from many plant types. In the larval stage, this pest attacks more than 20 species of cultivated and wild plants. For over twenty years, the onion caterpillar S. exigua has been the main target for chemical control but is still the main pest on onion crops. Spodoptera exigua attacks occur throughout the year in North Sulawesi and are spread over a wide geographical range, allowing genetic differences within the species. Gene mutations cause the occurrence of genetic diversity in a species in a population. High genetic diversity in individuals in a population can be one inhibiting factor in successfully controlling a pest species. Increasing knowledge about the biology of a pest species is very important to understand its habits, reproductive ability, and distribution which will later be used to limit and control the pest population.

Abstract

The mint plant (Mentha piperita L.) is one of the many aromatic herbal plants that produce essential oil commonly known as peppermint oil. Meanwhile, the soka flower plant (Ixora paludosa L.) is an ornamental plant that fills the planting elements with fast growth and beautiful, vigorous plants. This study aimed to assess the effect of lime insecticides combined with mint leaf extract (Mentha piperita L.) and soka flower extract (Ixora Paludosa L.) on red fire ants (Solenopsis invicta). This study used four red fire ant samples (Solenopsis invicta), which were divided into five treatment groups: X1 (75% mint leaf extract and 25% soka flower extract); X2 (75% soka flower extract and 25% mint leaf extract); X3 (50% soka flower extract and 50% mint leaf extract); Negative control (lime base); and Positive control (branded lime). The sample size for this study was 80 red fire ants (Solenopsis invicta), with each control group consisting of four fire ants, and the experiment was repeated four times. The Kruskal-Wallis test was used to analyze the data, revealing significant differences between the treatment groups. Therefore, the researchers concluded that the administration of 50% mint leaf extract and 50% soka flower extract effectively disrupted the activity of red fire ants

Abstract

The use of pesticides on highland vegetable crops by farmers is considered highly intensive. This is primarily due to favorable climatic conditions for developing plant pests and diseases. Pesticides are toxic bioactive chemical substances (at concentrations > 0.5 ppm). Each of these poisons carries risks to the environment and humans in their use. Pesticide residues are specific substances found in agricultural food crops or animal feed, either as a direct or indirect result of pesticide use. This research aims to determine the presence of pesticide residues in potatoes cultivated by the community of Moat Subdistrict, East Bolaang Mongondow Regency. This study adopts a qualitative descriptive approach with laboratory experimentation. Representative samples were taken from ten potato plantations in Moat Subdistrict, East Bolaang Mongondow villages. They were then analyzed at the Laboratory of Plant Protection and Quality Testing. Based on the research findings, the researchers concluded that six locations of potato tubers in 10 villages in Moat Subdistrict, East Bolaang Mongondow Regency, did not contain pesticides. In comparison, the remaining four locations showed pesticide content.
