Abstract

Biolarvicide is the larvicide derived from plants and relatively safe. The objective of this study was to determine the effect of pletekan leaf powder (Ruellia tuberosa), mimosa (Mimosa pudica), papaya (Carica papaya), and guava (Psidium guajava) on Culex quiquefasciatus larval mortality. The method was an experimental with a completely randomized design consisted of 5 treatments (0 gr, 0,25 gr, 0,5 gr, 0,75 gr, and 1 gr) and 5 repetitions for each plant. The data were analyzed by analysis of variance. Based on the results, leaf powder used in the study, namely guava leaves powder (1 gr), mimosa (1 gr), leaves of pletekan (1 gr), and leaves of papaya (1 gr) showed a very significant effect (P < 0,05) on Culex quiquefasciatus larval mortality. It can be concluded that the pletekan, mimosa, papaya, and guava had the potential as biolarvicide of Culex quinquefasciatus.

Abstract

PBL is a teaching method that can help students understand the subject matter and improve their problem-solving abilities. The purpose of this study is to see how the problem-based learning (PBL) model affects students' problem-solving abilities with reproductive system material. This is a pre-experimental study with a one-group pretest-posttest design. Non-probability sampling is used, along with total sampling. The research sample consisted of 39 students from Class XI. The data collection technique used pretest and posttest instruments, and the data analysis technique used was the One-Sample KS Test, with an average pretest result of 23.08 with a significance of 0.00, a posttest average of 85.18 with a significance of 0.03, and an average N-Gain of 0.81 with a significance of 0.01 as evidenced by statistical analysis, which states that the data significance is 0.05, indicating that Problem Based Learning has an effect.

Abstract

Sambung nyawa (Gynura procumbens(Lour.) Merr.) is a plant that can be used as herbal medicine such as healing cuts, lowering blood sugar levels, facilitating menstruation, and preventing cancer formation. The various properties possessed by sambung nyawa plants make these plants continue to be used and experience plant scarcity. Another alternative is to use endophytic fungi which are known as a source of efficacious medicinal secondary metabolites but have not been widely used. This study aims to isolate and identify the genus of endophytic fungi on sambung nyawa plants. The method used in this study was sampling, namely root organs, root bark, stems and leaves of sambung nyawa plants, making media using instant PDA media mixed with aquadest and antibiotics, endophytic fungi using direct planting techniques on PDA media in cups. petri, purification of endophytic fungi by eliminating fungi that are considered to be the same from their morphological characteristics until truly pure fungi are found, endophytic fungi help macroscopically by observing the color, texture, and pattern of the colony then observing microscopically using the culture slide technique then observing under a hyrox microscope by observing the type of spore, spore shape and hyphae. The results of this study were 12 isolates of endophytic fungi identified in 10 different genera, namely Nigrospora, Blastomyces, Fusarium, Pythium, Cladosporium, Trichoderma, Gliocladium, Papulaspora, Aspergillus, Monacrosporium.
