Abstract

Avocado (Persea americana Mill.) leaves contain saponins, tannins, flavonoids and alkaloids that have potential as larvicides. The purpose of this study was to determine the larvicidal activity of ethanol extract of avocado (Persea americana) leaves against Aedes aegypti larvae. The test was carried out on 210 larvae which were divided intro 7 groups, namely group I, II, III, IV, V which were ethanol extract of avocado leaves with concentration of 0,1%; 0,5%; 1%; 1,5%; and 2%. Positive control (group VI) was given Temephos 0,01% solution and group VII as negative control was only given Aquadest. Each treatment groups were observed for larvae death and counted every hour for 24 hours. LC50 and LT50 values were calculated using probit analysis. The results showed that ethanol extract of avocado leaf had larvicidal activity against Aedes aegypti larvae with LC50 = 0,03% at 3 hours and LT50 = at 1 hour 42 minutes. The ethanol extract of avocado leaf had a potential as larvicidal against Aedes aegypti larvae.

Abstract

Kesehatan mental remaja menjadi isu penting dalam konteks pendidikan perkotaan yang sarat dengan tekanan akademik, persaingan sosial, dan paparan media digital. Siswa SMA di perkotaan menghadapi risiko tinggi mengalami stres, kecemasan, hingga depresi yang dapat mengganggu proses belajar dan perkembangan sosial mereka. Penelitian ini bertujuan untuk mengeksplorasi hubungan antara kesehatan mental, pendidikan jasmani, dan relasi sosial di kalangan siswa SMA perkotaan dengan menggunakan perspektif sosiologi. Metode penelitian menggunakan pendekatan kualitatif melalui studi literatur eksploratif yang dipadukan dengan observasi fenomenologis di sekolah. Data diperoleh dari jurnal ilmiah, laporan kebijakan, dan pengamatan interaksi siswa, kemudian dianalisis dengan teknik analisis tematik. Hasil penelitian menunjukkan bahwa tekanan akademik dan penggunaan media sosial secara berlebihan meningkatkan kerentanan siswa terhadap gangguan kesehatan mental. Namun, pendidikan jasmani berperan sebagai faktor protektif yang membantu menurunkan stres, memperkuat rasa percaya diri, serta meningkatkan keterampilan sosial. Selain itu, relasi sosial yang positif dengan teman sebaya dan guru terbukti mendukung kesejahteraan mental, sementara isolasi sosial dan perundungan justru memperburuk kondisi psikologis siswa. Penelitian ini menyimpulkan bahwa kesehatan mental remaja di sekolah perkotaan dipengaruhi oleh interaksi kompleks antara sistem pendidikan, aktivitas jasmani, dan kualitas relasi sosial. Oleh karena itu, diperlukan pendekatan holistik yang mengintegrasikan program pendidikan jasmani, iklim sekolah yang suportif, dan penguatan jejaring sosial untuk mendukung kesejahteraan mental siswa SMA.

Abstract

This study aims to explain the role of physical education activities in supporting the mental health of high school adolescents in urban environments. This study uses a qualitative descriptive approach, with data collection techniques through in-depth interviews, observation of physical education learning activities, and review of documents related to school programmes. The data obtained were analysed using thematic analysis techniques to identify patterns, meanings, and connections between organised physical activities, such as sports games, fitness exercises, and motor activities, and the emotional, social, and psychological aspects of students. The results showed that regular participation in physical education helped students express themselves, manage stress, build self-confidence, strengthen social relationships, and balance academic demands and the need for activity. Overall, physical education played an important mediating role in promoting an active lifestyle and mental well-being among adolescents in urban areas.

Abstract

This study is a quantitative research aimed at determining the effect of fartlek training on the improvement of VO2Max endurance in PPLP/SKO Sulawesi Selatan athletes. The type of research used is an experiment with the independent variable being fartlek training and the dependent variable being the improvement in maximum oxygen volume (VO2Max). The population in this study consisted of all PPLP/SKO Sulawesi Selatan athletes, with a sample size of 25 people. Data collection techniques were carried out through tests and observation sheets, while data analysis used descriptive statistics and t-tests using the SPSS version 20.00 program. The results of the t-test showed a t-value of 11.195, which was greater than the t-table value of 1.71088 () with a significance value of . Based on these results, it can be concluded that there is a significant effect of Fartlek training on increasing VO2Max endurance in PPLP/SKO Sulawesi Selatan athletes.
