Improving the sexual health of our teenagers and preventing teenage pregnancy is a national priority that the current government of Bhutan with the help of concern stakeholders aim to reduce teenage conception rate and sexually transmitted infections by 2022 to the minimum. If we are to achieve this ambitious target, parents, teachers and paediatricians need to consider the sexual health needs of our teenage population and recognize times where we are able to offer advice, screening or signposting. As increasing number of Bhutanese youths are becoming victim of teenage pregnancy and STIs. The study was aimed to make awareness to our youth to improve their understanding on adolescent reproductive sexual health (teenage pregnancy, sexual activities STIs, HIV/AIDs) for positive behavioural outcome. Therefore, imparting applicable life skills education to our young minds has become indispensable to curb the aforementioned issues. The study was carried out in Ura Central School, Bhutan. The participants of the study consisted of 61 studying in class VIII and X and 25 teachers. The study adopted mixed method; quantitative approach included survey whereas for qualitative approach included semi-structured interview. Survey data were collected from 61 students and 25 teachers whereas interview data were collected from 10 students and 5 teachers. The study found the intervention (awareness programme via teaching, roleplay, discussion) effective with students in the post-data showing better understanding of the students regarding teenage pregnancy, sexual activities and STIs.</p> Lhawang Norbu Namchu Gurung ##submission.copyrightStatement## 2021-10-21 2021-10-21 7 27 10.9734/ajob/2021/v13i230181 Phenological Study of Elaeis guineensis (Jacq.) Growing in Ihiala, Anambra State, South-East Nigeria <p>The aim of the study was to provide a phenological data and baseline information on the phenology of <em>Elaeis guineensis</em> Jacq. The study was conducted with exotic species at Ihiala, South-East, Nigeria, a tropical climate. The initiation and completion of different phenophases of the tree, such as budding, leafing, flowering, fruiting and ripening were recorded at two weeks interval. The combination of the principal growth stages and the secondary growth stages produced 2-digit codes, were used to delineate the time-dependent phenophases. The results revealed that <em>E. guineensis</em> showed a cyclical and seasonal appearance of the phenophases observed in the course of the year. Bud formation and leaf development phenophases were very gradual and steady across the months observed. Peak flowering time of August through November and peak ripening time of April was recorded in this study. Also, the study revealed that difference existed in the extent of phenophases of the observed species. The study also showed that <em>E. guineensis</em> belong to the family (Arecaceae) had different time frames for the phenophases. It is concluded that the phenological records obtained from the study can be very useful in planning and management of orchards, and can provide reference records in tracing changes in the phenology of <em>E. guineensis</em> in the future.</p> Ochia, M.

J4 in Degrading Sago Bioplastics <p>Bioplastics made from sago flour have the potential to be developed into plastic-based industrial materials that are environmentally friendly and easily degraded by microorganisms.<em> A. flavus</em> DSFP.J1 and <em>A. niger</em> DFSP.J4 are microorganisms from a type of fungus that are proven to be able to degrade sago bioplastics, but have not yet obtained optimal degradation power. Therefore, this study aimed to obtain optimal conditions of the two isolates of fungi in degrading bioplastics made from sago flour at variable inoculum concentrations of 10, 20, 30,40, 50% v/w. The manufacture of sago bioplastics is done by adding acetic acid as a catalyst and added glycerol to form plastic properties in 15% sago flour, after being formed and cut to a size of 1 cm2. Observations to determine the degradation power were carried out after an incubation period of seven days to the next five weeks. The results obtained showed that the optimal conditions of <em>A. flavus</em> DFSP.J1 and in degrading sago bioplastics at 40% inoculum concentration with a degradation power of 56.52% in the fifth week of observation and tended to increase the degradation power on the following day, as well as <em>A. niger</em> DFSP.J4 optimally degrades at 30% inoculum concentration with a degradation power of 55.90% in the fifth week of observation.&nbsp; The results of the research, it can be concluded. Both the fungus <em>A. flavus </em>DFSP. J1 and <em>A. niger </em>&nbsp;DFSP.J4 showed that potentialy to be developed for further research to increase its degradation power higher and faster.</p> Tri Gunaedi Arsyam Mawardi Fawuni G. A. G.

The toxicity response was assessed using the inhibitory effect of the single and binary mixtures on isolates dehydrogenase activity; and 2,3,5 triphenyltetrazolium chloride (TTC) was used as the artificial electron acceptor. The binary mixtures were composed using fixed ratios of glyphosate and 2, 2 Dichlorovinyl dimethyl phosphate in ratios of 20% Gly:80% DDVP, 40% Gly: 60% DDVP, 50% Gly: 50% DDVP, 60% Gly: 40% DDVP and 80% Gly: 20% DDVP. Results obtained showed that the isolates exhibited different degrees of logistic and sigmoidal toxicity trends with areas of hormesis at low concentrations of the toxicants. Furthermore, isobolographic analysis on the toxic interaction of the mixtures presented both synergism and antagonism, based on the relative ratio of the component mixtures. Increasing concentration of glyphosate in the binary mixture caused a shift in the interaction effect from antagonism to synergism. Our findings showed that isolates exhibited tolerance to glyphosate and 2,2 dichlorovinyl dimethyl phosphate and their binary mixtures exposure at concentration range of 0-1000mg/L; above which has deleterious effects on the aquatic organisms. It is evident that there are considerable differences in pesticide sensitivity among the bacterial species and that the presence of glyphosate and 2, 2-dichlorovinyl dimethyl phosphate in the aquatic environment may present toxicological risk to microbial diversity.</p> C.
