Abstract

Childhood is a golden period for brain development. Musical activities such as listening, singing, and playing instruments involve various sensory and motor systems and can enhance brain function. These activities stimulate different areas of the brain and are believed to support cognitive functions, including concentration during learning. This study used a literature review method. Sources were collected from academic databases such as PubMed, Google Scholar, and ProQuest. The review found that musical activities enhanced the structure and function of several brain regions. Early musical training increased grey matter connectivity in hippocampus, primary motor cortex, supplementary motor area, and broca’s area. White matter development also occurred in motor cortex, occipital lobe, arcuate fasciculus, and corpus callosum. In addition, musical engagement activated brain's reward system, particularly involving dopamine, which supported persistence and focus in learning. Musical hobbies contributed positively to improvement of children's learning concentration. This occurred through mechanisms of brain neuroplasticity that were influenced by regular engagement with musical activities. It was recommended that musical activities be introduced from an early age, especially during golden period, with selection of appropriate types of music, such as classical music that promotes calmness and supports attention.

Abstract

Moringa oleifera leaves have long been recognized in traditional medicine for their anti-inflammatory properties. This review aims to comprehensively evaluate current scientific evidence from both preclinical and clinical studies regarding the anti-inflammatory mechanisms of moringa leaves. A systematic search of the literature was conducted using databases such as PubMed, Scopus, and Google Scholar, covering studies published up to 2025. Preclinical findings indicate that moringa leaf extracts exhibit significant anti-inflammatory activity through various mechanisms, including inhibition of prostaglandin synthesis, suppression of pro-inflammatory cytokines such as TNF-α and IL-6, and modulation of the NF-κB signaling pathway. In vivo animal models further demonstrate reductions in edema and inflammatory cell infiltration. Early-phase clinical trials suggest potential therapeutic benefits in managing mild to moderate inflammatory conditions; however, these studies remain limited in scale and methodological rigor. In conclusion, moringa leaves show promising and multifaceted anti-inflammatory mechanisms, warranting further large-scale clinical validation to support their use as a complementary therapeutic agent.

Abstract

Hair loss is a common condition found in various groups. Various factors can cause hair loss, including genetic factors, hormonal imbalance, stress, nutritional deficiencies, and certain medical conditions. The type of disorder that occurs can be hair loss (effluvium) or hair loss disorders to baldness (alopecia). The study aims to determine the effectiveness of non-SLS shampoo preparations with a combination of teak leaf extract (Tectona grandis) and virgin coconut oil (Cocos nucifera) in overcoming hair loss and increasing hair growth rate. The shampoo preparation was tested on mice with 4 treatment groups consisting of 1 control group and 3 groups of mice that were given treatment (P1 containing 1,5% teak leaf extract and 0% VCO, P2 containing 2% teak leaf extract and 0,15% VCO, and P3 containing 2,5% teak leaf extract and 0,30% VCO). The trial on mice was conducted for 21 days and the calculation of the length of the mouse fur using a caliper was carried out periodically for 7 days. The results of study showed that the third formula showed an increase in the rate of hair growth. The effect of shampoo that showed most significant difference was P3 with 2,5% teak leaf extract and 0,30% coconut oil. Shampoo products containing teak leaf extract and coconut oil have been proven to have potential to increase rate of hair growth. This shampoo formula can also reduce hair loss supported by scientific journals reporting that teak leaf extract can inhibit work of steroid 5-α reductase (5SAR) and secretion of Interleukin-1 Beta (1L-1β), where both compounds have a negative impact on hair growth.

Abstract

Durian (Durio zibethinus) belong to a popular fruits in Southeast Asia and is widely distributed across various regions, particularly in Indonesia. Karawang regency, as one of the part of west java province, is one of the producers of local durian, known as durian loji. Successful durian cultivation is influenced by various biotic factors, among which insect biodiversity plays a critical role in pollination, pest control, and nutrient cycling. However, comprehensive studies on insect diversity in durian agroecosystems, particularly in Karawang, remain scarce. This study aimed to explore the insect community structure within Loji durian plantations to provide baseline data on species composition and ecological roles. Field sampling was conducted using three methods: sweep nets for aerial insects, beating sheets for foliage-dwelling species, and pitfall traps for ground-active arthropods. A total of 29 insect morphospecies from 9 orders were identified, including Coleoptera, Hymenoptera, Diptera, Dermaptera, Orthoptera, Hemiptera, Odonata, Mantodea, and Lepidoptera. Our findings show that all morphospecies occupied various trophic levels, including herbivores, predators, and decomposers. These findings highlight the ecological significance of insects in maintaining durian plantation health and suggest the need for sustainable farming practices to conserve beneficial species while managing pests. Further research should investigate the seasonal variations and the impact of agricultural practices on insect community structure and diversity.

Abstract

Improving feed efficiency through local resources is essential for sustainable quail production. This study aimed to evaluate the effect of fermented local feed on the egg quality of laying quail. A randomized block design (RBD) was used, consisting of four treatments with four replications: RA (100% commercial feed/control), RB (90% commercial + 10% fermented local feed), RC (80% + 20%), and RD (70% + 30%). Data were analyzed using ANOVA followed by Duncan’s multiple range test. The results showed that the substitution of commercial feed with fermented local feed had no significant effect (P>0.05) on yolk index, albumen index, and eggshell thickness, but significantly improved yolk color (P<0.01). At weeks 7–8, values were: yolk index 0.504 ± 0.014, yolk color 5.65 ± 0.66, albumen index 0.071 ± 0.010, and eggshell thickness 0.209 ± 0.014. At weeks 12–13, values were: yolk index 0.488 ± 0.208, yolk color 5.70 ± 0.48, albumen index 0.075 ± 0.006, and eggshell thickness 0.205 ± 0.010. It is concluded that up to 30% of commercial feed can be replaced with fermented local feed without compromising egg quality. This finding supports the utilization of local feed resources in quail farming and offers a cost-effective alternative to commercial diets.

Abstract

Forage consisting of grass and legumes is an important aspect of ruminant but availability is often dependent on the rainy season so preservation technology is needed, namely silage. This study aimed to determine the nutritional content of silage made from a mixture of Pennisetum purpureum and Sesbania grandiflora with different doses of fermentation additives. A Completely Randomized Design (CRD) was used, consisting of four treatments with five replications. They were P0: (75% Pennisetum purpureum + 25% Sesbania grandiflora), P1: (75% Pennisetum purpureum + 25% Sesbania grandiflora + 0.1% additive), P2: (75% Pennisetum purpureum + 25% Sesbania grandiflora + 0.2% additive), P3: (75% Pennisetum purpureum + 25% Sesbania grandiflora + 0.3% additive). Each treatment was added 2% molasses and incubated for 21 days. The results showed that the addition of fermentation additives had no significant effect (P>0.05) on DM and OM content but had a highly significant effect (P<0.01) on increasing CP, EE, and TDN content and reducing CF content. The highest average DM and OM values were observed in P0 (21.02% and 89.27%, respectively), while the highest average increases in CP, EE, and TDN were found in P3 (15.31%, 2.85%, and 50.32%, respectively), and the greatest reduction in CF was also recorded in P3 (27.89%).

Abstract

Dental disease remains a major health concern in Indonesia, with a high prevalence across various age groups. This study aims to formulate and evaluate herbal toothpaste using Eichhornia crassipes (water hyacinth) leaf extract and eggshell powder, and to determine its antibacterial activity against Streptococcus mutans and Staphylococcus aureus. The toothpaste was prepared in three formulations with varying concentrations, followed by evaluation of its physical properties and antibacterial activity using the well diffusion method. Among the formulations, F1 containing 3% water hyacinth extract and 15 g eggshell powder showed optimal results. F1 fulfilled physical quality standards based on SNI 12-3524-1995, including pH, viscosity, and foam formation. Antibacterial testing demonstrated that F1 exhibited very strong inhibition zones of 21.87 mm against S. aureus and 21.50 mm against S. mutans. These findings indicate that a combination of water hyacinth extract and eggshell powder is effective as an active agent in herbal toothpaste. This research supports the utilization of abundant local waste materials as a sustainable alternative in oral health care formulations.

Abstract

Cyanogenic glycosides are hydrocarbon compounds that can bind to CN groups and sugars. Certain plants, notably higher plants, can perform cyanogenesis, forming cyanogenic glycosides as by-products of biochemical reactions. From a medical perspective, cyanide is known to negatively impact health, particularly the respiratory system, as it binds oxygen in the blood to toxic compounds. Symptoms of cyanide poisoning from food consumption include dizziness, weakness, vomiting, throat inflammation, and abdominal cramps. Acute poisoning and death have been reported from consuming food containing 50 – 100 mg of cyanide. This review utilizes a literature study method, focusing on national journals from the past decade accessed via Google Scholar. The findings identify five plant species containing cyanogenic glycosides: cassava, bamboo shoots, cassava leaves, raw Pangium edule seeds, and Dioscorea hispida tubers. Cassava, in particular, contains linamarin, a cyanogenic glycoside found in all parts of the plant, with bitter varieties generally having higher toxin levels.

Abstract

Starfruit (Averrhoa bilimbi L.) is a plant traditionally used as medicine, mainly due to its secondary metabolite content that has the potential as an antimicrobial agent. This study aims to evaluate the antimicrobial activity of A. bilimbi leaf extract against Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli bacteria. Extraction was carried out using three types of solvents: 100% ethanol, 100% ethyl acetate, and a mixture of ethanol-ethyl acetate (1:1) using the maceration method. Antimicrobial activity tests were carried out using the disc diffusion method to measure the inhibition zone of bacterial growth. The results showed that all A. bilimbi leaf extracts had inhibitory activity against both types of test bacteria. The extract with ethyl acetate solvent showed the largest inhibition zone against S. aureus and E. coli, followed by the mixed ethanol-ethyl acetate extract, and then the ethanol extract. These findings indicate that the active compounds in A. bilimbi leaves are more soluble in ethyl acetate and have the potential to be developed as natural antibacterial agents.
