Abstract

Gross motor skills are crucial abilities for daily life that involve the use of large muscles. Children with mental disabilities often face limitations in physical and mental aspects, which can hinder their gross motor development. This study employed a quantitative descriptive design to describe conditions without testing hypotheses. Data were collected through tests of flexibility, coordination, strength, speed, and endurance among students in grades I–VI at Dharma Bhakti Abcd Special School, Ngempon, Semarang Regency. The results showed that both boys and girls achieved a 100% score in the “good” category for flexibility. In coordination, boys were largely in the “less” category (47.1%), while girls achieved 100% in the “good” category. Strength tests indicated both groups were in the “moderate” category (100%). For sprint ability, boys were mostly “moderate” (85.7%), while girls were divided into “good” (40%), “moderate” (40%), and “less” (20%). Endurance results showed both boys and girls in the “less” category (100%). Overall, the findings highlight strong flexibility but challenges in coordination and endurance, providing insights for educators and therapists in designing targeted interventions.

Abstract

Football in Indonesia continues to grow rapidly, as reflected in the increasing number of clubs across various regions, including Pemalang Regency. However, the presence of many clubs has not translated into improved achievements due to the absence of a structured development system. Key issues include limited communication with stakeholders, unstructured training programs, and the lack of qualified coaches capable of designing and evaluating effective training. This study employed a descriptive qualitative approach with data collected through observation, interviews, and documentation. The subjects consisted of 48 respondents: 16 administrators, 16 coaches, and 16 players. Data validity was ensured using source triangulation, while analysis was conducted through data reduction and presentation. The findings indicate that coaches generally demonstrate good attitudes during training and matches, but most lack coaching licenses and the ability to design structured programs. Of 16 U19 clubs, only 3 coaches held official licenses and 1 had a youth assistant license. Overall, the results highlight that although coaches show positive behavior, the absence of licensing and structured training knowledge hinders the development of U19 football in Pemalang Regency.

Abstract

Indonesia is renowned for its rich natural resources, particularly medicinal plants with significant therapeutic potential. This study examined how the ethanolic extract of curry leaves (Murraya koenigii) can act as an antioxidant and antibacterial agent against Propionibacterium acnes, the primary cause of acne vulgaris. This study used phytochemical screening to identify secondary metabolites, such as alkaloids, flavonoids, tannins, saponins, and glycosides, which are associated with biological activities such as killing bacteria and protecting cells from damage. The DPPH method for testing antioxidants showed that the extract had an IC50 value of 45.88 mg/L, which is not significantly different from quercetin as a reference, at 23.7 mg/L. This result is still significant for the strong antioxidant category. We assessed antibacterial efficiency using a disc diffusion technique, which showed a zone of inhibition corresponding to the extract concentration. The widest zone of inhibition, measuring 17.77 ± 0.15 mm, was recorded at a concentration of 250 mg/mL, classifying its activity as strong by existing standards. These findings underscore the extract's promise as a natural acne therapy, addressing bacterial growth and oxidative stress. Furthermore, these results support the development of safe and efficacious pharmaceutical or cosmetic products derived from natural components. Future investigations should examine synergistic formulations and enhance bioavailability to optimize therapeutic outcomes.

Abstract

One plant that has been shown to aid wound healing is turmeric. Turmeric has been scientifically proven to have choleretic and anti-inflammatory properties. Turmeric contains curcumin, which has antibacterial and antioxidant qualities that can accelerate the migration and re-epithelialization of cells useful in wound healing, including myofibroblasts, fibroblasts, and macrophages. This study aimed to determine the effect of turmeric mother extract gel on wound healing in male white rats (Rattus norvegicus). This study was conducted using experimental tests. Turmeric extract was prepared using 96% ethanol solvent with a maceration process. A 2 cm long incision wound was made on the back of white rats. The test animals were then divided into five groups to receive different treatments. Groups 3, 4, and 5 received turmeric mother extract gel with concentrations of 1%, 5%, and 10%, while Group 1 was negative control and Group 2 was positive control. The results showed that the incision wounds in male white rats could heal faster - on average, about 7.10 days - when treated with 96% ethanol extract of turmeric mother with doses of 1%, 5%, and 10%. This study concludes that a 10% turmeric mother extract gel is the best method to accelerate wound healing.

Abstract

The Editorial Board has issued this editorial note in the form of a review to inform contributors about changes to the scope of the Journal of Wallacea Forestry Research (JPK Wallacea) following the transfer of management from Balai Penerapan Instrumen Lingkungan Hidup dan Kehutanan Makassar to Hasanuddin University's Forest Conservation Study Program in 2023. JPK Wallacea is no longer limiting its scope to forestry and is expanded to cover biodiversity in general by incorporating the term Wallaceae, which is a biogeographical area located between the continents of Asia and Australia. This area is well known for its unique biodiversity both on land and in water. The Wallacea region's biodiversity is famed for its distinctiveness yet, it is on the verge of extinction. Thus, the Editorial Board chose to focus on the scope of JPK Wallacea on scientific, technological, and policy conservation features. This scientific publication is expected to make a substantial contribution to the biodiversity conservation effort in the Wallacea region and its surroundings.

Abstract

Antibacterials are substances that can interfere with the growth or even kill bacteria and have the side effect of antibacterial resistance. One effort to reduce resistance is choosing to use natural bacterial ingredients. One plant that can potentially contain antibacterial activity is malacca leaves (Phyllanthus emblica). The contents of this plant include flavonoids, alkaloids, tannins, saponins, and steroids/triterpenoids. This research aimed to prove the antibacterial activity test of malacca leaf extract. The stages in this research included phytochemical screening and testing the antibacterial activity of ethanol extract from Malacca leaves for Staphylococcus aureus and Staphylococcus epidermidis bacteria using the diffusion method using paper discs. The characteristics of malacca leaf simplicia obtained were water content of 4.6%, water-soluble content of 28%, ethanol-soluble essence content of 23.33%, total ash content of 2.00%, and insoluble ash content of 0.5%. The results of phytochemical screening showed the presence of flavonoids, saponins, tannins, glycosides, and steroids/triterpenoids. The antibacterial test results of malacca leaf extract at concentrations of 500 mg/ml, 400 mg/ml, 300 mg/ml, and 200 mg/ml have an antibacterial effect against Staphylococcus aureus and Staphylococcus epidermidis, and there is no difference in the effectiveness of the inhibitor against gram-positive and negative grams.

Abstract

This study aimed to develop a formulation of mango fruit juice (Mangifera indica L.) as a moisturizing agent in the form of hand cream. The main component of mango, sucrose, has the ability to attract moisture from the air due to its hydroxyl groups, which helps reduce water evaporation from the skin. Mango juice was obtained by blending the mango pulp using a juicer, followed by the addition of 0.1% sodium metabisulfite as an antioxidant. The extract was then concentrated using a freeze-drying technique at -40°C and 2 atm pressure. The cream formulation developed was an oil-in-water (m/a) emulsion type, with mango fruit juice concentrations of 2.5%, 5%, 7.5%, and 10%. These were compared to cream containing 2% glycerin and a blank formulation. Various tests were conducted to evaluate the physical quality of the cream, including homogeneity, pH, stability, emulsion type, and irritation tests using a moisture-checker. The results showed that mango fruit juice was successfully formulated into a homogeneous m/a cream, with a pH ranging from 5.55 to 7.04, and remained stable for up to 12 weeks of storage. The cream formulated with mango juice was proven to increase skin moisture without causing irritation. The higher the concentration of mango fruit juice, the greater the moisturizing effect. The 2.5% concentration provided a moisturizing effect comparable to cream containing 2% glycerin. The best moisturizing effect was achieved at a 10% concentration, which increased skin moisture by up to 14.4% after 4 weeks of use. This mango juice is effectively used in m/a type creams as a skin moisturizer. Keyword: Mango fruit juice, cream, skin moisturizer
