Abstract

The objective of plant hybridization is to generate alternative superior phenotypes with the aim of decreasing the dependence on wild orchid exploitation in nature. Although interspecies crosses in Dendrobium are very likely to occur and there is a low chance of experiencing bud depression, interspecies crosses have the potential to encounter several problems, including failure of embryo development resulted to the seeds unable to germinate. Media formulation is the most essential component in the success of in vitro culture of orchid seeds. Therefore, this study aimed to obtain new Dendrobium hybrids and the best media formulation for germination and seedling growth. A total of three experiments were conducted including hybridization, the impacts of basic media namely (1) MS, (2) VW, and (3) foliar fertilizer both with and without the addition of tryptone, on seedling germination. The results showed that there was no compatibility barriers observed in all crosses. Foliar fertilizer + tryptone media was recommended for orchid seedlings because it produced better growth and roots up to 8 months after planting (MAP). For best results on Dendrobium hybrid seedlings, MS + tryptone media up to 6 MAP was used followed by deflasking into VW + tryptone to stimulate optimal root growth before hardening.

Abstract

This experiment aimed to study the formation of scalps and  banana shoots 'Tanduk' in vitro in response to thidiazuron (TDZ). Shoot explants measuring ± (1 x 1 x 1) cm3 were cultured in precondition media (MS+ 5 mg/l benzyladenine) for 4 weeks, then transferred to treatment media, namely MS + TDZ. This experiment was carried out using a completely randomized design with 3 replications and 7 treatments of TDZ concentrations (0.5; 1.0; 1.5; 2; 2.5; 3; 3.5; 4.0 mg/l).  Each experimental unit consisted of 5 bottles, each containing one explant. Observations of scalp number were carried out at 8 weeks of age. The scalps were subcultured on MS+5mg/l BA media to induce shoots. After 8 weeks in the shoot induction medium, the number of shoots was recorded.  The results showed that at 8 weeks on the culture all of the explants formed scalps, with the highest number of scalps (6 scalps/explant) was at 1 mg/l TDZ.  The scalp number decreased to 4.4 to 3.5/explant as the TDZ concentration increased from 1.5 to 4 mg/l. After 8 weeks on shoot induction media containing 5 mg/l BA, the highest number of shoots (3.8 shoots/explant) was obtained on the scalp from the 0.5 mg/l TDZ treatment. The shoot number decreased to (3.2-1.9/explant) with increasing TDZ concentrations from 1.0 to 4.0 mg/l.Keywords: Tanduk, plantain, thidiazuron, in vitro, scalp.

Abstract

Indonesia is one of the largest cassava producing countries in the world with various types and advantages. Waxy clones have a high starch content and therefore they can be used as a food substitute for rice. Tissue culture through somatic embryogenesis is an effective technique for rapid and mass seedling propagation. This research aimed to determine the effect of the type and concentration of auxin 2,4-D or picloram and the addition of NAA on the formation of Waxy cassava clone somatic embryos. This research used a completely randomized design (CRD) which was arranged in a non-factorial. Auxin 2,4-D and picloram were used at four concentration levels: 0 mg.l-1, 8 mg.l-1, 10 mg.l-1, 12 mg.l-1, and additional NAA treatment of 6 mg.l-1 each. Results showed that MS + 6 mg.l-1 NAA treatment produced the highest callus weight. Meanwhile, the percentage of embryonic callus and number of embryo was higher in the treatment of MS + picloram 12 mg.l-1 and NAA 6 mg.l-1 (19,05 ± 5,82 %) and MS + 8 mg.l-1 2,4-D + 6 mg.l-1 NAA (11,11 ± 3,17 %) with 5,48 ± 3,56 and 4,93 ± 1,95 embryos, respectively. Thus, auxin picloram 12 mg.l-1 + NAA 6 mg.l-1 were the most effective in inducing the formation of somatic embryos on waxy cassava clone.

Abstract

Diabetes mellitus is a non-communicable disease whose prevalence continues to increase globally, primarily due to unhealthy lifestyles. A healthy lifestyle, which includes a balanced diet, regular physical activity, stress management, and adequate sleep, plays a crucial role in preventing diabetes mellitus. This community service programme aims to increase public understanding of the importance of a healthy lifestyle as a preventative measure for diabetes mellitus. The activity, conducted in Tosa Village, targeted women from the Family Welfare Movement (PKK) through lectures, discussions, and Q&A sessions. The results showed an increase in the average pre- and post-test scores, from 5.39 to 12.79. It is hoped that this health education programme will help the community change unhealthy behaviors to adopt healthy ones in their daily lives to avoid diabetes mellitus and other diseases.

Abstract

The growth and production of cassava can be increased through various efforts, including the use of superior varieties, fertilization, the addition of organic materials, and the application of growth regulators (PGR). Naphthaleneacetic acid (NAA) and indole-3-butyric acid (IBA) are PGRs that have been widely documented to stimulate root initiation and development in cuttings. The application of aauxin mixtures on cassava cuttings followed by fertilization and the addition of organic materials is expected to improve the growth and yield of cassava. The aim of this experiment is to study the effects of the application of an NAA and IBA mixture (1:1) and the type of fertilizer on the growth and yield of the Garuda variety of cassava. This research is designed using a clustered randomized block method with three replications. The design used is factorial 2x3, consisting of two main treatment factors. The first factor is the combination of growth regulators NAA and IBA in a 1:1 ratio at three concentration levels, namely 0 ppm, 500 ppm, and 1,000 ppm. The second factor includes the type of fertilizer used, which is a single inorganic fertilizer and a combination of inorganic fertilizer with cow manure. Each experimental unit in this study consists of 10 cassava cuttings planted in an orderly manner with a planting distance of 1 meter x 1 meter between plants. The results of the experiment showed that the application of inorganic fertilizer produced plant growth and the number of productive roots equivalent to the use of inorganic fertilizer + cow manure. The application of a mixture of auxins NAA and IBA (1:1) at concentrations of 500 ppm and 1,000 ppm significantly increased the growth of shoots, the number and weight of productive roots of the Garuda variety cassava, but both treatments resulted in cassava growth and yield that were not different. Key words: Cassava, cow manure, growth, IBA, NAA, yield

Abstract

Rice growth and yield can be increased through various efforts, including the use of "high-yielding varieties, fertilization, soil conditioners with application of plant growth regulators (PGRs). Soil conditioners namely as biochar are carbon products that can enhance plant productivity through enhancing the physical, chemical, and biological characteristics of the soil, while cytokinine benzyladenine (BA) is a PGR that has been widely documented to stimulate cell growth, cell division, and differentiation in rice plants. The purpose of this study was to determine the effect of biochar and benzyladenine (BA) on the growth and yield of the IR Nutrizinc rice variety. Data collection was carried out in October 2024 - February 2025 in Kampung Payung Rejo, Pubian District, Central Lampung Regency. The treatments were arranged factorially (2x3) using a completely randomized design with 3 replications. Factor I was without biochar and given 20 tons/ha of biochar. The second factor was 3 benzladenin (BA) concentrations, namely 0 ppm, 50 ppm, and 100 ppm applied by spraying on the surface of the plant at 20, 30, and 40-days after transplanting, while the biochar application was implemented 2 weeks before transplanting. Observed variables included plant height, maximum tillers per clump, count of productive tillers, length of panicles, and grains per panicle, percentage of empty grains per panicle, dry harvested grain yield, dry harvest grain yield, 1000 grain weight and dry weight of the crownThe Bartlett test was employed to assess the homogeneity of variance among treatments then analysis of variance was carried outIf a notable difference existed between treatments, the BNT test was carried out at the 5% significance level. The findings indicated that applying 20 tons/ha of biochar enhanced the yield components in terms of dry harvested grain, dry milled grain, and dry shoot weight The application of 50 ppm BA was able to increase the growth and yield of grain compared to without benzyladenine (BA). The combination of biochar and BA enhanced the growth and yield of grain in terms of the number of grains per panicle, dry harvested grain, and dry milled grain. The use of 20 tons/ha biochar combined with 50 ppm BA enhanced the yield of the IR Nutrizinc

Abstract

Promoter methylation of the hTERT gene in blood DNA has been proposed to be an epigenetic molecular clock because it is negatively correlated with ageing. Saliva is an alternative source of DNA because it contains buccal cells. Currently, the correlation of hTERT promoter methylation and ageing using saliva is not known. This study aimed to determine: first, the correlation between hTERT promoter methylation and ageing in saliva, as a source of non-invasive DNA sampling, instead of blood was determined. Second, the influence of sex on the methylation of the hTERT promoter in ageing was evaluated. A cross-sectional study design was used, and 119 subjects were recruited, consisting of 25 children (1-5 y.o), 42 teens (17-19 y.o), 16 adults (20-50 y.o), and 36 elderly (60 to 84 y.o). Promoter methylation of the hTERT of extracted DNA was determined using the MSRE (methyl-specific restriction enzyme) method. The relationship between age and the percentage of hTERT methylation was assessed using the Pearson test. The percentage of hTERT methylation in saliva DNA was negatively correlated with age r= -0.4305 (p-value <0.05). Negative correlation was also found in men (r= -0.376) and women (r=-0.43). Negative correlation between hTERT and ageing has been confirmed in saliva as a noninvasive sampling method. The benefit of this research in ethical and social considerations may encourage a greater participation in ageing research, particularly in underprivileged communities, thus democratising access to scientific advancements in longevity studies.
