Abstract

Identity crises are common in adolescence, which can lead to destructive behavior. Sport affects behavior indirectly through positive competitive attitudes and negative stereotypical destructive behavior. This study analyzes sports education on self-esteem in special and regular sports education. This type of research is quantitative, with an ex post facto approach. The subjects in the study were 200 respondents consisting of special sports class (KKO) students, regular class students, and parents/guardians of ninth-grade junior high school students. The data collection technique used a self-esteem questionnaire from the Rosenberg Self-Esteem Scale (RSES). Test the instrument's validity with Pearson's product-moment correlation coefficient, while the instrument reliability test uses Cronbach's Alpha technique. The data analysis technique used is a one-way ANOVA test. The results showed that there were differences between KKO and regular students. Student participation, especially adolescents at the junior high school (SMP) level in sports activities, has a high level of tendency. The existence of special sports classes (KKO) whose curriculum is designed systematically and structured to implement sports training programs and harmonious general education has a psychological effect on adolescent students. Thus, it can be concluded that there is an effect of sports education on self-esteem in KKO students. This research implies that sports education that is managed properly has a positive impact on adolescents.

Abstract

Usaha Mikro, Kecil, dan Menengah (UMKM) memainkan peranan penting dalam perekonomian nasional, khususnya dalam menciptakan lapangan kerja dan meningkatkan pendapatan masyarakat. UMKM Manalagi, yang bergerak di bidang produksi keripik singkong dan pisang, menghadapi tantangan dalam mengelola sumber daya terbatas agar biaya produksi dapat diminimalkan. Penelitian ini menggunakan metode Linear Programming untuk menentukan kombinasi produksi optimal yang meminimalkan total biaya produksi dengan memperhatikan batasan bahan baku, waktu kerja, serta permintaan minimum produk. Keripik singkong membutuhkan biaya Rp 4.000 per unit, bahan baku 2 kg, dan 2 jam kerja, sedangkan keripik pisang memerlukan biaya Rp 5.000 per unit, bahan baku 3 kg, dan 4 jam kerja. Ketersediaan bahan baku terbatas 60 kg dan waktu kerja maksimum 80 jam. Hasil analisis menunjukkan solusi optimal pada produksi 5 unit keripik singkong dan 10 unit keripik pisang dengan total biaya minimum Rp 70.000. Kombinasi ini memenuhi seluruh kendala dan permintaan pasar secara efisien. Model Linear Programming ini memberikan dasar yang kuat untuk pengambilan keputusan dalam perencanaan produksi UMKM yang hemat biaya dan terukur.

Abstract

Research on analysis of macroalgae community structure on different substrates in Sabang waters to identify, analyzing diversity, abundance, and important value index. The data collection method was carried out by purposive sampling using a plot of 1x1 m2 with 10 plots per transect. Sampling was carried out at three stations, namely Station I on Pasir Putih with a medium fine sand substrate, Station II at Anoi Itam with a gravel sand substrate, and Station III on Rubiah Island with a fine sandy clay substrate. Data were analyzed using the Importance Value Index (IVI) and the Shannon-Wiener Diversity Index. The environmental parameters at each station that were measured were substrate particles, temperature, brightness, depth, and current velocity, while the chemical parameters were salinity, pH, COD, phosphate, and nitrate. The results of the study found 2615 macroalgae individuals consisting of three divisions. Chlorophyta division consists of 9 species, Rhodophyta was 7 species, and Phaeophyta was 1 species (Dyctyota dichotoma). The highest Important Value Index at each research station consisted of the Chlorophyta division with two species, namely Dictyosphaeria cavernosa (IVI = 59.18) and Halimeda opuntia (IVI = 54.15). The value of the diversity index (H') of macroalgae in Sabang waters is moderate, namely in Pasir Putih as much as 2.18, Anoi Itam and Rubiah Island as much as 2.01, and 1.97, respectively. The study concluded that the macroalgae community structure in Sabang waters exhibits moderate species diversity, with the Chlorophyta division, particularly Dictyosphaeria cavernosa and Halimeda opuntia, showing the highest importance value indices across different substrates.

The author believes that radicalization is a complex process that can be influenced by various factors, including psychological, social and economic factors. This article also touches on the issue of deradicalization, namely the process of reversing radicalization and promoting moderate beliefs and behavior. The author notes that deradicalization programs have been implemented in various countries, including Indonesia, but much still needs to be done to address the root causes of radicalization. Overall, this article provides a comprehensive overview of radicalism and its implications, highlighting the importance of understanding this complex phenomenon to address the problem of terrorism and promote coexistence.
