Abstract

Cervical cancer is a type of cancer that occurs in the cervix which is characterized by the presence of massive tissue cells that grow continuously and are not limited to the cervix and more than 90% are caused by HPV infection. Cervical cancer is in second place at 10.69% after breast cancer at 19.18%. Various efforts have been made to minimize cervical cancer but are inversely proportional to the effects on the body. On the other hand, Indonesia is rich in flora diversity, one of which is the bidara plant (Ziziphus mauritiana) which can produce fruit and has the potential as an anticancer. The purpose of this study was to determine the interaction of the active compound Ziziphus mauritiana on HER2 as an anticancer computationally. The research was conducted using online web databases including the PubChem web, PDB, and software including PyRx, AutoDock, PyMOL, and Discovery Studio 2021. The results of the study were the interaction of the active compound Ziziphus mauritiana against HER2 with PDB code: 6TFZ as a computational anticancer, namely clindamycin with the value of biding affinity is -7.6 kcal/mol; levetiracetam and nonanoic acid with a binding affinity value of -4.8 kcal/mol were rated lower as cervical anticancer compared to trastuzumab with a binding affinity value of -8.8 kcal/mol. Keywords: Cervical cancer, computing, Ziziphus mauritiana

Abstract

Flies are insects that act as vectors of mechanical disease, because disease agents such as pathogenic bacteria do not change in the fly's body but only move disease agents from polluted places to clean places. Flies can be controlled with plant-based insecticides. The purpose of this study was to determine the effect of frangipani leaf juice (Plumeria acuminata) on the death of house fly (Musca domestica). This research is an experimental research with the design of "Post Test Only With Control Group Design". The concentration of juice used is 70%, 80%, 90%, 100%. Each treatment was tested on 10 flies with three replications. Each concentration was tested by spraying on the flies with three sprays and observations were made every 10 minutes for one hour. The results of the study were analyzed using linear regression with a 95% confidence level. The results showed that there was an effect of frangipani leaf juice on the death of house flies (p = 0.00). Based on the results, it can be concluded that the juice of frangipani leaves (Plumeria acuminata) has an effect on the death of the house fly (Musca domestica). Keywords: kamboja leaves, house filies, vegetable insecticide

Abstract

Salt stress is a condition of the soil with high concentration of soluble salts and it causes bad growth for plants. Only few crops can survive in soil with high salt concentration. This study aimed to determine the growth and anatomical responses of curly pepper plants root given with low of NaCl at early vegetative phase, as well as to determine the optimal concentration for the growth of curly pepper plants. The experiment was conducted at the research farm of Sawitsari, Laboratory of Plant Structure and Development, and Laboratory of FALITMA Faculty of Biology UGM. This Research was designed in Completely Randomized Design (CRD) with variation of low NaCl treatment. Variation of treatment were water as control (G0), early NaCl 50 mM+ advanced 150 mM (G1), early NaCl 75 mM+ advanced 150 mM (G2), early NaCl 100 mM+ advanced 150 mM (G3), early NaCl 125 mM+ advanced 150 mM (G4), and early NaCl 150 mM+ advanced 150 mM (G5). The parameters observed were the anatomical parameters of roots (the thickness of cortex, and vascular bundle, roots diameter); growth of plants (plant height, internodes length, root length, and plants biomass); and biochemical parameters (roots proline). Quantitative data were analyzed using ANOVA followed by DMRT at a significant level of 5%. Anatomical structure of roots were analyzed descriptively. The result showed that low of NaCl stress at early vegetative phase treatment increased the plant height, internodus length, root length, root biomass, and highest root diameter in G1, meanwhile the highest thickness of root cortex was found in G3. The treatment reduced root stele diameter in G3 compare with G5. If the treatments were compared with control, all parameters measured at low of NaCl treatment showed reduction except root length and root proline content. The optimal concentration of salt for the optimal growth of curly pepper plants was a treatment with NaCl 50 mM+ advanced 150 mM (G1). Keywords: NaCl stress, pepper, growth, anatomical response, vegetative phase
