Abstract

Degenerative diseases have become a complex problem around the world. Until now, degenerative diseases have become the biggest cause of death in the world. Approximately, 17 million people die early each year due to the global epidemic of degenerative diseases. Peoples in developing countries still rely on medicinal plants for primary health care. The knowledge for medicinal plant were passed down through generation with little written documentation. This study aimed to document the indigenous medicinal plants used for the treatment for degenerative diseases in East Lombok, Indonesia and to find leads on prospective plants for further ethnopharmacology research based on quantitative ethnobotany index. The ethnomedicinal data were collected through interview and discussion among local healers and plant collected with the help of local guide also herbarium was made to aid specimen confirmation. Ethnomedicinal data was analyzed using use value (UV) along with fidelity level (FL). A total of 20 informants (traditional healers) were interviewed and from the study we can documented the use of 63 plants for the treatment of degenerative diseases. The UV ranged from 0,05 (Sesbania grandiflora) to 0,35 (Carica papaya), while the highest FL (100%) was found for 29 species. Based on the ethnobotanical index (UV and FL) from each plant we can recommend 15 species for further ethnopharmacological study to determine their therapeutic effects and mechanism of action. This study revealed rich ethnomedicinal knowledge from the community in East Lombok for the treatment of degenerative disease.

Abstract

Plants that can be used as pesticides are Gadung tubers. Gadung tubers contain cyanide acid to kill armyworm pests because they contain dioscorin toxins which can cause nervous disorders. The purpose of this study was to determine the effect of Gadung tuber extract (Dioscorea hispida) on Caterpillar mortality (Spodoptera exigua) in Shallot plants. This type of research is experimental research. This study used a completely randomized design (CRD). The sample used was 5 caterpillars (Spodoptera exigua) in each polybag with 5 repetitions for each concentration of Gadung tuber extract, namely 0%, 0.5%, 1.0%, 1.5%, 2.0% and 2.5%, so the total Caterpillar used was 150 Caterpillars. Gadung tuber extraction was carried out by maceration method with methanol solvent. Data were analyzed using a one-way analysis of variance at the 95% significance level, followed by DMRT (Duncans Multiple Range Test). The results showed that the Gadung tuber extract had a significant effect on the mortality of caterpillars (Spodoptera exigua) because the F count was greater than the F table (45.40>2.62), and the DMRT test results showed that the optimal concentration of Gadung tuber extract was 2.5%. Therefore, it can be concluded that the extract of Gadung tuber (Dioscorea hispida) affects the mortality of Caterpillars (Spodoptera exigua) in Shallots (Allium cepa).

Abstract

Fertilizer is one of the most important needs for plants. Fertilizing can be done by using inorganic fertilizers or organic fertilizers. Long term fertilizing by using inorganic fertilizers without adding the organic matter could potentially reduce soil fertility and lead to not optimal growth of the plant. This study aims to determine the effect of liquid organic fertilizer (LOF) made from rabbit urine, NPK fertilizer, and the combination of both fertilizers on the growth of bok choy, and to determine the best fertilizer dosage for the growth of bok choy. This study uses a Completely Randomized Design consisting of 2 factors, the dose of rabbit urine LOF and dose of NPK fertilizer; 4 dosage levels each in triplicates. Data was analyzed using ANOVA followed by DMRT Test. The results indicates that the application of LOF made from rabbit urine, NPK fertilizer, and the combination of both fertilizers increases  plant height, leaves number, leaf area, wet weight, dry weight, and chlorophyll total of bok choy. DMRT (a 5%) test shows the best dosage applied for enhancing growth parameter are 6 ml of LOF plus 0,4 gram of NPK for plant height, wet weight, and dry weight, the 4 ml of LOF plus 0,6 gram of NPK for leaves number and leaf area, and the 4 ml of LOF plus 0,4 gram NPK for chlorophyll total.
