The Springs of Tiga Rasa Rejenu is one of the springs located at one of the peaks of the seven peaks in the Muria mountains. The Tiga Rasa Springs are located at the peak of Argo Wiloso Rejenu, Kudus Regency. The diversity of vegetation around the Tiga Rasa Springs has an important role in the sustainability of springs source and discharge. This study aims to determine the composition of plants, vegetation forms, the index of importance value of vegetation components, and the abiotic environment impact around the springs. The method used is explorative descriptive analysis by dividing the area into four research stations based on the direction of the eye. At each research station there are three sample plots. Each station is divided into three sampling points with a size of 20m x 20m for trees, 10m x 10m for poles, and 5m x 5m for saplings and 2m x 2m for seedlings. Abiotic environmental parameters measured are air temperature and humidity, light intensity, soil temperature, soil pH, total dissolved solids, and water salinity. The research results around the Tiga Rasa Rejenu spring are that the H' values at the highest level of see dlings is fern Diplazium esculentum, the H' values at the highest level of saplings is the royal palm tree Roystonea regia, and the H' values at the highest level of poles and trees is Pterocarpus indicus. At all stations obtained average H? value is 1.96 then the vegetation around the Tiga Rasa spring classified to medium plant diversity and medium community stability. Abiotic factors effect on the environmental conditions around the Tiga Rasa Rejenu springs.

Ixora and Psychotria are two distinct genera within the Rubiaceae family found at the Bogor Botanic Gardens. Despite taxonomic differences at the genus and subfamily levels, these plants share certain characteristics that necessitate identifying similarities. This study aims to identify resemblances between Ixora and Psychotria by examining their leaf architecture and evaluating significant morphological characteristics across recognized variables. The data analysis objective is to identify commonalities in leaf architecture and key distinguishing characteristics. Species under investigation include Ixora javanica (Blume) DC., Ixora paludosa (Blume) Kurz, Ixora coccinea L., Ixora chinensis Lam., Psychotria angulata Korth., and P. viridiflora Reinw. ex Blume. Thirteen characters were used to identify shared traits and influential features. Research findings showed both Ixora and Psychotria exhibit various characteristics. Cluster analysis indicated strong correlation among subjects under investigation, primarily due to shared characteristics. Distinguishing features significantly contributing to differentiation are leaf abaxial surface color and leaf base morphology. It can be concluded that abaxial leaf surface color holds potential as a distinguishing characteristic for Ixora, while leaf base exhibits distinguishing features for Psychotria.

Indonesia is one of the countries located on the equator and has a tropical climate. Due to this climate, Indonesia has a high level of flora and fauna. One of them is the diversity of tropical flowers and plants. One of the most diverse tropical flower habitats in Indonesia is Curug Lawe in Semarang Regency, Central Java. This study aims to determine the diversity of tropical flowering plants in the Curug Lawe waterfall area, Semarang Regency. The method used in this study is descriptive exploratory with a qualitative approach. The results of observations of tropical flowering plants in the Curug Lawe area obtained 17 families of Asteraceae, Heliconiaceae, Iridaceae, Commelinaceae, Araceae, Balsaminaceae, Costaceae, Verbenaceae, Gesneriaceae, Lamiaceae, Lythraceae, Amaranthaceae, Proteaceae, Rubiaceae, Malvaceae, Oxalidaceae, and Rosaceae. These results show the high diversity of tropical flowers in the Curug Lawe area because it has supportive environmental conditions. Tropical flowering plants have various benefits, including being used as medicines, ornamental plants, as cooking ingredients, anticancer, antioxidant, antibacterial, anti-inflammatory, antimicrobial, as insecticides, and industrial oils.

Wax apple Delima and Citra Cultivars are two superior non-climacteric tropical fruit commodities from Demak Regency which have similar morphological characters but have different fruit characteristics. Identification wax apple cultivars from Demak regency using DNA barcoding approach has not been researched yet. The aims of this research are to analyze the morphological similarities of wax apple between Delima and Citra cultivars and to identify genetic variations of wax apple Delima and Citra using trnL-trnF intergenic spacer for molecularly authentication. The results shown that there were no differences in the environmental parameters of the wax apple two cultivated area in Demak Regency. According to the morphological approach, the Delima and Citra cultivars in Demak Regency were grouped separately into Delima and Citra clusters with a similarity index of 61.5% (Citra cultivars) and 60.5% (Delima cultivars) and separated based on the origin of their cultivation area. Genetic variations between wax apple Delima and Citra in Demak Regency consisted of deletions (9delA & 17delA) and conserved P6 loop in all compared cultivars. The possibility of heteroplasmy R (A,G) found at 73 nucleotide number in Delima Betokan cultivar and Citra cultivars (Betokan and Jungpasir). Meanwhile, Delima Jungpasir cultivar is K (G,T). There were P8 stem-loops with different lengths between Delima cultivars (Betokan and Jungpasir) and the same length in Citra cultivars (Betokan and Jungpasir). Therefore, the trnL-trnF intergenic spacer has not been thoroughly used in wax apple Delima and Citra authentication due to the presence of a secondary structure which causes the loss of the electropherogram signal so that the nucleotide sequence cannot be read.

Information digitization is one of the steps that can be taken to improve public services. One example of the use of information digitization is the creation and uploading of village profiles on YouTube to introduce villages to the general public. At this time, video village profiles are essential for various purposes, such as mapping village potential, branding, and program socialization. Village governments often have difficulty creating profiles for this video, especially in Lanpasa Village. The method used in Community Service (PKM) is to use Science and Technology Substitution. Lanpasa Village is one of the villages in Seruyan Raya District, Seruyan Regency, Central Kalimantan Province. Thus, this Community Service (PKM) aims to make a profile video of Lanpasa Village. Lanpasa Village profile video, in this video describes the geographical location, economic conditions, education, and social conditions as well as the potential resources of Lanpasa Village. The creation of this profile video is expected to introduce various aspects of the village's excellence, such as natural beauty, cultural wealth, and distinctive products, to a wider audience.

Endophytic fungi are microorganisms that inhabit plant tissues without causing harm to their hosts. Hippobroma longiflora (L.) G. Don (kitolod) is known to contain secondary metabolites with antibacterial potential. This study aimed to isolate and evaluate the antibacterial activity of endophytic fungi from the leaves and flowers of kitolod against Escherichia coli and Staphylococcus aureus. Isolation was performed by surface sterilization using 1% NaOCl, 70% ethanol, and sterile water, followed by cultivation on PDA medium. Nine isolates were obtained, consisting of four from flowers and five from leaves. Extracts from PDB cultures were tested using the disc diffusion method (30 µL/disc). Results showed that isolate BK1 exhibited strong antibacterial activity against S. aureus (11.16 mm) and moderate activity against E. coli (9.71 mm). Isolates BK3 and DK3 also displayed strong inhibition zones. The positive control (chloramphenicol) produced very strong inhibition, while the negative control (sterile water) showed none. The antibacterial activity is presumed to originate from secondary metabolites of endophytic fungi, indicating their potential as natural antibacterial sources. Further studies are needed to determine MIC values and conduct molecular identification of the selected isolates.
