Abstract

Orchids are more economical and tall than plants and other decorations. One of the orchids cultivated is the Vanda orchid. Seed orchid size is small and does not have endosperm, so it is not easy to germinate in nature, so tissue culture is one multiplication orchid in amount a lot and a short time. This study aims to know the growth of the seed orchid Vanda helvola on different media for 12 days after plant. Seed orchid V. helvola grown on modified Murashinge and Shoog (MS), modified Vaccin and Wend (VW) media and organic media. The research was conducted at the Tissue Culture Laboratory of the UPT Center for Food Crops and Horticulture (BBIPTH), Luwus Tanaban, from February to May 2023. The research method used was observation and experimentation, and the research design used RAK (group random design). Research shows modified MS Media, modified VW and organic capable change seeds orchid V. helvola. Modified MS and modified VW media can induce seed orchid V. helvola germination, and MS media can induce formation protocol.

Abstract

Grasshopper is one type of insect known as a plant pest that quite affects agricultural production. Grasshoppers also have benefits as natural predators and maintain ecological balance. One area where no research has been carried out on grasshopper diversity is Dompu Regency, West Nusa Tenggara, Indonesia. This research was conducted at 4 locations in Dompu, including corn, ex-corn, intercropping, and Doroncanga agricultural land, by making four transects at each location. Grasshoppers were collected using the insect net, and hand collecting was carried out at 07.00 and 16.00 WITA. The environmental factors that were calculated were air temperature, light intensity, wind speed, and air humidity, while the biotic factors observed were plant vegetation at each location and predators. Data analysis was performed using the Shannon-Wiener diversity index, evenness index, dominance index, and Margalef index. The results of this study indicate that Dompu Regency has the potential for diversity of grasshoppers with moderate criteria where the diversity of grasshoppers is strongly influenced by plant vegetation and human treatment on agricultural land.

Abstract

Land conversion in Dompu Regency is increasingly rapid due to the high demand for corn. Many studies have shown that land conversion not only results in a decrease in the number of species but also changes the structure and composition of insect communities. The purpose of this study was to analyze the diversity, correlation of diversity with abiotic factors and distribution patterns of aerial and ground insects found in agricultural land. The study was conducted in four locations: corn fields, rice fields, sacha inchi fields, and intercropping fields. The research method used was a quantitative exploration method that combines active and passive observations including VES, Sweeping nets, Pitfall traps, and yellow traps. The results of insect identification at the four research locations found 8 orders with 34 species divided into 4.37% decomposers, 17.27% pollinators, 31.59% predators, and 46.77% pests. The highest diversity was found in corn fields with an index of 3.06, followed by rice fields with 3.04, sacha inchi fields with an index of 3.007, and the lowest in intercropping fields with an index value of 2.96. The results of the Pearson correlation analysis found that humidity has a positive influence on species diversity and evenness, but is negatively correlated with dominance.

Abstract

This study aims to document and record the diversity of medicinal plant species, the diseases they are used to treat, methods of preparation and administration, plant parts utilized, sources of plant materials, plant species use value Spesies (UVs). An exploratory survey was conducted using a qualitative research approach. The study identified 42 species belonging to 23 families, with Zingiberaceae being the most represented family (6 species). A total of eight types of traditional medicines were recorded, used to treat 26 categories of diseases. The most commonly utilized plant parts were fruits (32.22%), while stems and bark were the least used (2.22%). The most frequent method of preparation was pounding (33.33%), whereas frying and boiling were the least common (5.56%). The dominant route of administration was oral consumption (30%), while eating and hair washing were the least frequent (5%). In terms of acquisition, most medicinal plants were purchased (41.86%), while wild collection (18.60%) was the least practiced. Based on the calculation of species use value spesies (UVs), the highest values were recorded for black glutinous rice, coconut, and nutmeg (UVs = 0.33), whereas the lowest were observed for dill (Anethum graveolens L) and papaya (UVs = 0.02).
