Abstract

Masa kanak-kanak dini adalah masa di mana anak mengalami pertumbuhan dan perkembangan yang dimulai dari usia 0-6 tahun. Anak-anak tumbuh dengan karakteristik yang berbeda sesuai dengan aspek perkembangan anak. Pada tahap ini, aspek perkembangan anak, termasuk perkembangan sosial-emosional, memiliki peran penting dalam perkembangan anak karena anak belajar berinteraksi dengan lingkungannya, bermain, berbagi, dan bersosialisasi. Tentu saja, mereka harus dibiasakan sejak dini agar anak dapat menghadapi tantangan yang terjadi di sekolah dan lingkungan rumah mereka. Kegiatan sosialisasi yang dilaksanakan di Balai Desa Timbuolo Tengah, Kecamatan Botupinge, Kabupaten Bone Bolango, dihadiri oleh kepala desa beserta stafnya, orang tua murid TK dan guru PAUD serta masyarakat setempat. Kegiatan ini memberikan pemahaman tentang perkembangan sosial emosional anak dalam menghadapi tantangan di lingkungan pra sekolah. Perkembangan adalah proses di mana pertumbuhan berubah seiring waktu, tergantung pada kematangan dan interaksi dengan lingkungan. Perkembangan sosial emosional anak perlu dikembangkan sedini mungkin karena jika sulit untuk berkembang maka anak akan kesulitan berkomunikasi dengan orang lain dan anak akan kesulitan menghadapi tantangan di lingkungan sekitarnya.

Abstract

Mucosa surface is the body's initial barrier against pathogens, rely on secretory Immunoglobulin A (s-IgA) for localized immunity. This study investigated the impact of Etlingera elatior extract on s-IgA levels and mucosal fluid secretion in mice challenged with Staphylococcus aureus. The research method used an experimental design with seven treatment groups, i.e negative control (P1), positive control (P2), and five groups with E. elatior extract administration at concentrations of 40% to 80% (P3-P7). Data were analyzed using ANOVA and Tukey's subset test to determine differences between groups. The results showed an increase in s-IgA levels as the extract concentration increased, with the highest level at P7 (1842.25 ng/mL). Conversely, mucosal fluid secretion decreased, with the lowest level at P7 (21.5 L). Statistical analysis showed significant differences between treatment groups (p0.05). The increase in s-IgA levels and normalization of mucosal fluid secretion are thought to be caused by bioactive content such as flavonoids and alkaloids which have immunostimulant and anti-inflammatory properties. The study revealed that E. elatior extract is effective in increasing s-IgA levels while controlling mucosal fluid secretion in mice infected with Staphylococcus aureus. These findings suggest the potential of E. elatior extract as a natural potential immunostimulant to support the treatment of mucosal infections.

Abstract

The problem of beggars in Palangka Raya City is one of the complex social issues, reflecting social inequality and the failure of an inclusive social protection system. This study uses a qualitative descriptive approach to analyze the implementation of the social rehabilitation program run by the Palangka Raya City Social Service to deal with beggars. This study collected data through interviews, observations, and documentation from various informants, including Social Service employees, social assistants, and beggars who had participated in the program. The study results indicate that the social rehabilitation program, which includes data collection, mental coaching, skills training, and social assistance, still faces various obstacles. The main challenges are low participation of beggars, limited rehabilitation facilities, a limited number of social assistants, and difficulties in social reintegration. In addition, the skills training provided is not fully practical due to limited job opportunities and post-rehabilitation support. However, some beggars have successfully undergone rehabilitation and live independently. This study recommends improvements in the capacity of rehabilitation facilities, the number of social assistants, a more holistic approach, and stronger economic empowerment to increase the program's effectiveness. It is hoped that with these steps, the social rehabilitation program can significantly impact beggars in Palangka Raya City.
