The people of Tengger, Indonesia have used plants as traditional medicine for a long time. However, this local knowledge has not been well documented until recently. Our study aims to understand the utilization of plants in traditional medicine by the people of Tengger, who inhabit the Ngadisari village, Sukapura District, Probolinggo Regency, Indonesia. We conducted semi-structured and structured interviews with a total of 52 informants that represented 10% of the total family units in the village. The parameters observed in this study include species use value (SUV), family use value (FUV), plant part use (PPU), and the relative frequency of citation that was calculated based on fidelity level (FL). We successfully identified 30 species belonging to 28 genera and 20 families that have been used as a traditional medicine to treat 20 diseases. We clustered all the diseases into seven distinct categories. Among the recorded plant families, Poaceae and Zingiberaceae were the most abundant. Plant species within those families were used to treat internal medical diseases, respiratory-nose, ear, oral/dental, and throat problems. The plant species with the highest SUV was Foeniculum vulgare Mill. (1.01), whereas the Aloaceae family (0.86) had the highest FUV. Acorus calamus L. (80%) had the highest FL percentage. The leaves were identified as the most used plant part and decoction was the dominant mode of a medicinal preparation. Out of the plants and their uses documented in our study, 26.7% of the medicinal plants and 71.8% of the uses were novel. In conclusion, the diversity of medicinal plant uses in the Ngadisari village could contribute to the development of new plant-based drugs and improve the collective revenue of the local society.

Abstract. Diet of high lipids cause hyperlipidemia, which marked by an increase of total cholesterols, triglycerides, LDL-C, and decreasing of HDL-C. Hyperlipidemia lead the occurrence of atherosclerosis, one of factors that trigger cardiovascular disease, as hypertention; coronary heart and stroke. Parijoto (M. speciosa) is endemic plants in Asia with a distribution center in Malaysia, Indonesia and Philippines. Parijoto contain phytochemical components such as flavonoids, saponins and kardenolin. Flavonoid potensial as an antioxidants and can improve the hyperlipidemia condition. This study was aimed to determine lipid profiles and atherogenic index of hyperlipidemic Wistar rats (R. norvegicus Berkenhout, 1769) which given the methanolic extract of Parijoto (M. speciosa). The research was done with pre and post test randomized control group design. Rats were given a mixture of duck yolk and reused cooking oil (1:1) orally as much as 1% of body weight (BW) for 30 days. After hyperlipidemia achieved, rats were divided into 5 group: normal rats, hyperlipidemic rats, hyperlipidemic rats were given the methanolic extract of Parijoto (M. speciosa) 500 mg/kg, 1000 mg/kg, and 1500 mg/kg BW. Blood samples were collected when rats in hyperlipidemia conditions and after treatment with the methanolic extract of Parijoto (M. speciosa) for 30 days. The data of total cholesterol, HDLCholesterol, LDL-Cholesterol level, and atherogenic index were analyzed using ANOVA followed by Tukey test at 5% significance level. The result showed that giving of methanolic extract of Parijoto (M. speciosa) in hyperlipidemic rats reduced the total cholesterol, LDL-Cholesterol levels, and increased of HDL-cholesterol levels significantly (p<0.01), so atherogenic index reduced significantly too (p<0.01). Total cholesterol and LDL-Cholesterol levels were positively correlated with the atherogenic index, whereas HDL-cholesterol levels were negatively correlated with the atherogenic index.

Abstract. Saputro TB, Purwani KI, Ermavitalini D, Saifullah AF. 2019. Isolation of high lipids content microalgae from Wonorejo river, Surabaya, Indonesia and its identification using rbcL marker gene. Biodiversitas 20: 1380-1388. Microalgae are unicellular organism which possesses various biologically active metabolites that used in food, cosmetic, pharmaceutical, nutraceutical, and bioenergy industries. One of the most important active metabolites found in microalgae is lipid which can be converted into biodiesel. The higher amount of lipid produced will increases the amount of biodiesel that can be obtained. Although, the production of active metabolites in microalgae has rather fluctuated as it is difficult to obtain the pure cultures of microalgae since it has a cryptic phenomenon. This problem can be solved through identification technique using molecular markers or DNA Barcoding. This research used rbcL gene as the molecular marker in species identification. rbcL gene encode ribulose-1,5-bisphosphate carboxylase (RubisCo) in chloroplast genome. Furthermore, microalgae were isolated from 3 different stations of Wonorejo river estuary, Surabaya, East Java, Indonesia. The isolated microalgae were then identified based on Freshwater algae: identification and use as bioindicators book. Eight isolates were successfully identified as Mycrocystis sp., Nostoc sp., Chlorella sp., Tabellaria, Synedra, Nitzschia, Navicula, and Closteriopsis. Out of eight, only 3 species that has a good potential to be developed as biodiesel sources i.e Chlorella sp., Synedra sp., and Navicula sp. that produce 21,20%, 20,30%, 27,20% of total lipids over their biomass. The genomic DNA from those three candidates were then isolated and used as a template to amplify rbcL gene. The obtained fragment of rbcL gene was sequenced and then submitted to the Basic Local Alignment Search Tool (BLAST). The result of BLAST used for alignment and phylogenetic tree construction. The result from BLAST shows the same results as the genus observed by microscopy observation. Overall, this research provides information about the genetic variety of microalgae in Wonorejo which has high potential to be further developed as biodiesel.

Soybean (Glycine max L.) is wellknown as a plant that posses an extra nutrition and many proteins and has a major role in improving people’s nutrition status. The environmental factors are the main obstacle in soybean production. High rainfall frequency can lead the waterlogging phenomenon which potentially decrease the production rate of soybean. Crop improvement are the best solution to solve the problems. The purpose of this research was to determine the tolerance level and physiological response of irradiated soybean, Grobogan and Anjasmoro varieties in waterlogging condition. 60CGamma were used to irradiate the seeds with 25Gy, 50Gy, and 100Gy dosages. This research were conducted in vegetative stadia with 100%, 150%, 200% concentration of water that dispersed into medium and control as comparison. Based on the data, the irradiation has a complex responses in plant morphology. The irradiated plant height was not significantly different among all treatments. While the leaf’s wide, root length, nitrogen in leaf, root nodules, chlorophyll content, fresh weight and dry weight are decline as the waterlogging concentration increased.

Jatropha curcas is currently known as an alternative source for biodiesel production. Beside its high free fatty acid content, J. curcas also contains typical diterpenoid-toxic compounds of Euphorbiaceae plant namely phorbol esters. This article present the transcription profile data of genes involved in the biosynthesis of phorbol esters at different developmental stages of leaves, fruit, and seed in Jatropha curcas. Transcriptional profiles were analyzed using reverse transcription-polymerase chain reaction (RT-PCR). We used two genes including GGPPS (Geranylgeranyl diphospate synthase), which is responsible for the formation of common diterpenoid precursor (GGPP) and CS (Casbene Synthase), which functions in the synthesis of casbene. Meanwhile, J. curcas Actin (ACT) was used as internal standard. We demonstrated dynamic of GGPPS and CS expression among different stage of development of leaves, fruit and seed in Jatropha.
