Abstract

Penelitian ini bertujuan untuk menganalisis perbedaan antara Metode Canny Edge dan Metode Region Segmentation Active Contour dalam aplikasi deteksi watermark pada uang kertas menggunakan Matlab. Dalam penelitian ini, citra uang kertas yang digunakan ada dari nominal Rp 5.000 hingga Rp 100.000, dan ada 4 kondisi uang kertas yang digunakan sebagai citra, yaitu Normal, Terlipat, Sobek, dan Print. Metode pertama, Metode Canny Edge, digunakan untuk deteksi tepi objek pada citra, sementara metode kedua, Metode Region Segmentation Active Contour, dilakukan segmentasi wilayah objek dengan memanfaatkan kontur aktif. Hasil penelitian menunjukkan bahwa Metode Canny Edge memiliki tingkat akurasi 88%, sedangkan Metode Region Segmentation Active Contour memiliki tingkat akurasi 87%. Metode Canny Edge lebih efektif dalam mendeteksi tepi objek dengan kontras tinggi, sedangkan Metode Region Segmentation Active Contour lebih unggul dalam mendeteksi wilayah objek yang kompleks atau tidak teratur. Penelitian ini dapat menjadi panduan dalam memilih metode deteksi watermark yang sesuai untuk meningkatkan keamanan uang kertas dan mencegah potensi pemalsuan.

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.
