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 philo...

Aluminum exposure is a serious public health problem, especially among workers in the informal aluminum foundry sector. Research on aluminum (Al) is important to advance our understanding of its impact on physiological systems. Here, we investigated the effect of exposure to aluminum longitudinal histological changes on the liver and kidneys of male mice. Mice were separated into six groups (4/group): group 1, group 2, group 3 received vehicles, and group 4, group 5, group 6 were administered a single dose of Al at 200 mg/kg b.w. by intraperitoneally every 3 days for 4 weeks. Post-sacrifice, kidneys and liver were isolated for examination. While Al did not impact the body weight gain of male mice across all groups, it caused liver damage including sinusoidal dilatation, enlarged central veins, vacuolar degeneration, and pyknotic nuclei in one-month-old mice. Furthe...

Kawasan Situ Gunung kaya akan keanekargaman hayati, salah satunya adalah lumut. Lumut (Bryophyta) merupakan salah satu kelompok dari tumbuhan tingkat rendah yang memiliki peranan sangat penting bagi ekosistem dalam menjaga sirkulasi hara, keseimbangan air, dan dapat digunakan sebagai indikator biologis lingkungan. Tujuan dari penelitian ini adalah untuk mengetahui keanekaragaman jenis lumut yang terdapat pada Taman Wisata Alam Situ Gunung. Penelitian dilaksanakan pada bulan Mei sampai dengan Juli 2021. Metode penentuan area lokasi penelitian dilakukan dengan purposive sampling dan penggambilan data menggunakan metode jelajah (deskriptif eksploratif). Hasil penelitian ditemukan terdapat 15 jenis lumut yang terdiri dari 11 jenis lumut sejati (9 suku), 3 jenis lumut hati (3 suku) dan 1 jenis lumut tanduk (1 suku).

Araceae is often used by the public as medicine, food sources, and ornamental plants. Therefore, the Araceae is often used as an interesting research object and conservation efforts have commenced maintaining its sustainability. The purpose of this research was to determine the species of living Araceae and the potential possessed by each living Araceae species in the conservation area of the Bogor Botanical Gardens. This research was conducted on 8-9 June 2021 to determine the diversity and potential of the Araceae in Bogor Botanical Gardens. The method used in this research is the exploring method and data analysis using descriptive method. The result of this research revealed there were 60 species of Araceae consisting of 25 genera. The genera with the highest number of species are Philodendron. Two species of them are Araceae which has a habitat in the water...

Bananas are easily damaged fruits, so the selling value of bananas will decrease according to the age of the fruit after harvest. Storage of fruit in various temperatures also has not been able to extend the banana fruit shelf life. The potential of bananas as a food source that can be stored can be done through the processing of bananas into banana flour. The banana flour training carry out at the Biology Laboratory of FMIPA UNJ with a participant from RW 03 and 05 Rawamangun District. The making of banana flour is done in two technique. The first technique is to peel the skin previously then the fruit is immersed in a 10% salt solution for 10-20 minutes. The second technique is done by steaming raw bananas for 10-20 minutes before stripping and soaking in a salt solution. Bananas that have been peeling are then slicing thinly to make cassava chips.

The technology introduced in this community service activity is the cultivation of family medicinal plants in yards using the verticulture method. The purpose of this community service activity is to convey information about the cultivation of family medicinal plants through lectures, discussions, and direct practice of cultivating family medicinal plants in yards using the verticulture method. Evaluation of participants' knowledge improvement was carried out by pre- and post test after counseling and cultivation practices. Skills participants are carried out when evaluating the practice of cultivating medicinal plants in their yards. The results of the activity showed an increase in basic knowledge regarding the types, benefits, and techniques of cultivating family medicinal plants from technology. Family medicinal plant service activity is classified as successful and beneficial, due to increased knowledge more than 60 in average test scoring. The skills evaluation showed that some residents were able to plant and maintain family medicinal plants on a narrow plot of land using the proper verticulture method. The results of the cultivation of these medicinal plants, apart from being one of the real actions of plant greening, can also be in the form of powder products which can then be consumed as a body health measure or sold. </jats:p>

Corythucha marmorata, native to North America and specialist on asteraceous plants, has been reported to exploit sweet potato (Convolvulaceae) in Japan. Here we examined the capability of females to oviposit and of nymphs to grow on both a conventional host (goldenrod, Solidago altissima) and novel hosts (four sweet potato cultivars), of which the test insects had virtually no experience of contact at the population level. We then tested whether female preference and offspring performance were correlated. Nymphal survival and development time were always significantly greater on goldenrod, followed by sweet potato cultivars Caroline Lea, Benisengan, Narutokintoki, and Beniazuma in that order. Female oviposition preferences showed a similar order. On higher-ranked plants, the females accepted the plant faster and had higher fecundity. When goldenrod was included in the analysis, nymphal development time and survival rate were significantly related to preoviposition period. When goldenrod was excluded, nymphal survival rate was still significantly related to preoviposition period. These results support the theory that females lay their eggs on the most suitable host to maximize offspring fitness, even though C. marmorata had no experience with sweet potato cultivars. As C. marmorata is a hemimetabolous insect, in which adults and nymphs have a similar feeding habit and exploit the same habitat, this relationship seems plausible.
