Abstract

Colchicine can inhibit spindle formation so that doubled chromosomes fail to separate during anaphase cytologically to induce mutations that produce polyploid plants. Yellow kepok banana is a triploid banana. The supply of yellow kepok bananas is hampered by conventional cultivation methods and the limited availability of quality seeds. This study aims to determine the effect of adding colchicine compound to tissue culture media on the mitotic index, chromosome number, and chromosomal abnormalities in yellow kepok bananas and the formation of polyploid plantlets. This study was included in the experimental study by conducting mitotic preparation and observing morphology after the test sample was induced by colchicine. The results of the research that has been done show that the addition of the compound colchicine to the tissue culture medium of yellow kepok banana causes a decrease in the mitotic index, an increase in the number of chromosomes, the presence of chromosomal abnormalities, the formation of polyploid plantlets, and an increase in the number of roots, but there is a reduction in root length.

Abstract

The amount of garbage that accumulates in the waters causes environmental damage which is getting worse. The breakdown of plastic waste into smaller particles that have been degraded is called microplastic. This study aims to analyze the number of particles, shapes, and types of microplastic polymers found in the water and sediments of Mahitam Island. The research location was determined by purposive random sampling with three stations based on plastic sources, namely Station I, Station II, and Station III, which had different characteristics from laboratory-based testing for seawater and sediment. Microplastic analysis on seawater samples was carried out by adding a solution of 70% ethanol, 30% H2O2, and 30% NaCl, and on sediment samples was carried out by adding a solution of FeSO4 (0.05 M), NaCl, and 30% H2O2. The content of the number of particles and the shape of microplastics were analyzed using a microscope, while the analysis of microplastic polymers using FT-IR. The first thing to do is to extract microplastics The forms of microplastic found are Fiber, Film, Fragments, and Pellets. The highest number of microplastic particles was the type of film for water samples at Station 1 and Station 2 for sediment samples. The types of polymers found in water and sediments on Mahitam Island are polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and polystyrene (PS) which come from plastic waste. Microplastics are known to originate from the use of plastic originating from tourist activities and originating from the sea currents of Mahitam Island.

Abstract

Anopheles mosquito shared a breeding site with the vannamei shrimp (Litopenaeus vannamei). Anopheles mosquito larvae commonly live in both stagnant fresh and brackish water. The potential breeding habitat of Anopheles mosquito larvae may be rice fields, pools or ponds, swamps, ditches, and slow-current streams. One of the effective strategies to control malaria is to apply chemical insecticides. Pyriproxifen is a larvicide that contains juvenile hormone-like compounds. Juvenile hormone-like compounds can affect mosquito morphogenesis, characterized by the failure of the larvae to develop into pupae. With a completely randomized design, the shrimp fry was divided into 4 groups,  6 repetitions, 20 individuals each. Shrimp fry in each experimental unit was placed and maintained in plastic jars containing 2.5 L of brackish water. The results showed that the insect growth regulator (IGR) with the active ingredient pyriproxyfen at various concentrations had no significant effect on the growth, mortality, and survival of vannamei shrimp fry.  It can be concluded therefore that pyriproxifen larvicide was safe to be used for controlling malaria mosquito vectors in hatcheries and breeding ponds of vannamei shrimp.

Abstract

As a megadiversity country, Indonesia is home to a large number of flora and fauna, one of which is the butterfly. The Bogor Botanical Garden, situated at the center of Bogor City, not only serves as a green open space but also as a conservation area for plants and animals composed in it.  This study aimed to assess the diversity of butterfly species in Teijsmann Park and Soedjana Kassan Park, Bogor Botanical Garden through inventory and identification.  Sampling was carried out at spots that were 100 meters apart from each other on a walked-line transect defined at the two parks. The diversity parameters assessed and analyzed are relative abundance, relative frequency, Shannon-Wiener (H’) diversity index, Evenness index (E), and dominance.  In a total of 202 sample individuals, there were identified 38 species of butterflies belonging to 5 families namely Papilionidae, Pieridae, Nymphalidae, Lycaenidae, and Hesperiidae. The highest abundance found in Teijsmann Park is Ypthima philomela from the Nymphalidae family and Zizina otis from the Lycaenidae family. Species with the highest frequency are Junonia hedonia and Ypthima philomela from the Nymphalidae family. On the other hand, the highest frequency and abundance found in Soedjana Kassan Park was Leptosia nina from the Pieridae family. Teijsmann Park showed a slightly higher value of diversity and evenness indexes (H'=2.62, E=0.84) when compared to Soedjana Kassan Park (H'=2.50, E=0.76).

Abstract

Indonesia is an agricultural country with the majority of the population working in the agricultural sector. According to the Central Statistics Agency of Indonesia, rice production in 2022 is estimated at 9.58 million tons, down by 0.04 million tons or 0.41 percent compared to 2021 which was around 9.62 million tons. The rise and fall of rice production was influenced by several problems. One of the causes of the delay in rice production is leaf blight caused by Xanthomonas oryzae pv. oryzae reducing rice yields by 30-40%. This research was to examine the use of teak leaf extract in inhibiting the growth of X. oryzae bacteria. The results showed that there was an effect of various concentrations of teak leaf extract (Tectona grandis) on the inhibition zone of X. oryzae. The effective concentration of teak leaf extract in inhibiting Xanthomonas oryzae bacteria is 20%.

Abstract

The rice fields of Sidorejo Village have the potential for dragonfly diversity. This study aims to analyze fluctuations in the diversity and abundance of dragonflies in three ecosystem conditions of rice fields in Sidorejo Village, Bengkulu Tengah. Sampling using purposive sampling with the cruising method. Data analysis was carried out descriptively through the identification of characteristics to obtain the name of the species. After the species name was obtained, the relative abundance, Shannon Wienner diversity index, and species evenness index were calculated. The results of the study found that the harvest ecosystem had the highest diversity and abundance of dragonflies (13 species and 45 individuals). The species that were consistently found in three types of ecosystems were Orthetrum sabina, O. testaceum, and Pantala flavescens. The species with the highest relative abundance was O. sabina with 32%. The diversity index ranged from 1.32 (post-harvest) to 2.25 (harvest). The highest evenness index was in the post-harvest ecosystem at 0.95, and the lowest was in the harvest ecosystem at 0.87. The results of this study are expected to show that the diversity and abundance of dragonflies fluctuate depending on seasonal ecosystem conditions in the rice fields.

Abstract

Indonesia a tropical country that remains warm all year, has the largest biodiversity. This study aims to determine the diversity of bats of the order Microchiroptera in Rau Cave, Wolasi, Conservation (Protected) Forest area, around Aoma Village, South Konawe Regency. Data collection was carried out using a mist net measuring 6 x 2 meters which were stretched in front of the mouth of the cave at 16.00 before the bats came out looking for food and harvested at 06.00-0.700. The trapped bats were identified using the Sulawesi Bat and its role in the health sector, and other relevant references. The results showed that there were 26 trapped bats consisting of  5 species, namely Rhinolopus arcuatus (Prok Bruk Sulawesi), Hipposideros ater (Barong gauld), Dobsonia viridis (Kubu Hijau), Miniopterus australis (Tomosu australi) and Hipposideros dinops (Barong horsfield). The species found consisted of 2 families, namely the families Rhinolopidae and Hipposideridae, and consisted of 2 genera, namely the genera of Dobsonia and Miniopterus. The diversity index shows a value (H') = 0.986, which indicates a low category in diversity and a Margalef wealth index (R) of 0.26. It is necessary to conserve plant species both for eating insects and for food sources for Microchiroptera bats in their feeding ground
