Abstract

Tanah gambut merupakan salah satu jenis tanah yang daya dukung tanahnya rendah, sehingga perlu dilakukan stabilisasi tanah. Metode perbaikan tanah yang dilakukan pada penelitian ini adalah stabilisasi kimiawi menggunakan serbuk cangkang kerang dan fly ash. Serbuk cangkang kerang mengandung kalsium karbonat (CaCO3) yang akan mengikat partikel tanah dan fly ash yang memiliki kandungan silika (SiO2) memberikan pengaruh terhadap kenaikkan pH tanah. Penelitian ini menggunakan metode eksperimen di Laboratorium, standar pengujian menggunakan Standar Nasional Indonesia. Pengujian dilakukan dengan menggunakan tanah gambut asli tanpa campuran dan tanah gambut yang telah dicampurkan serbuk cangkang kerang dengan persetase 15%, 18%, 21% dan fly ash 10%. Hasil penelitian menunjukkan adanya bahan tambah dapat meningkatkan nilai CBR tanah gambut dan mengubah tingkat keasaman tanah gambut. Nilai CBR tanah gambut meningkat seiring dengan bertambahnya persentase Serbuk Cangkang Kerang dan fly ash. Nilai CBR tertinggi terdapat pada persentase 21% Serbuk Cangkang Kerang dan 10% fly ash sebesar 4,938%, dibandingkan dengan nilai CBR tanah gambut asli sebesar 2,370%. pH tanah gambut asli yang didapat sebesar 2,87 dan pada pH tanah tambut yang telah ditambahkan Serbuk Cangkang Kerang dan Fly Ash sebesar 6.

Abstract

Menstrual stress is a common reproductive health problem among adolescent girls, which can interfere with learning activities, concentration, and overall quality of life. This community service activity aimed to improve the ability of female students to manage menstrual stress through education and practice of deep breathing techniques at SMPN 2 Rambutan, Banyuasin Regency. The activity used a one-group pretest–posttest pre-experimental design involving 30 female students who had experienced menstruation. Health education was delivered through interactive lectures, discussions, and practical demonstrations of deep breathing techniques, while evaluation was conducted using pre-test and post-test questionnaires on menstrual stress levels. The results showed a reduction in menstrual stress, with most participants shifting from moderate stress before education to mild stress after the intervention. These findings indicate that deep breathing techniques are effective in helping students independently manage menstrual stress. Therefore, health education combined with practical deep breathing exercises is recommended to be implemented continuously in schools as a promotive and preventive strategy for adolescent reproductive health.

Abstract

Stress among early adolescent girls in junior high school is an increasing health concern due to academic demands, social pressure, digital exposure, and menstrual related discomforts. Complementary interventions such as deep-breathing techniques offer a simple method that can be implemented in school settings to rapidly reduce stress. This study aimed to examine the effect of deep-breathing techniques on menstrual related stress among ninth-grade female students at SMPN 2 Rambutan, Banyuasin Regency.  A pre-experimental one-group pretest–posttest design was used. The sample consisted of 60 students selected from the ninth-grade population. Stress levels were measured using the Perceived Stress Scale (PSS-10) focusing on stress during menstruation before and after a single deep-breathing session. Data were analyzed using the Wilcoxon test. The results showed a significant reduction in stress scores after the intervention (p < 0.001). The proportion of students in the high-stress category decreased from 20% to 6.7%, while those in the low-stress category increased from 10% to 30%. The mean stress score decreased from 21.35 ± 4.82 to 15.42 ± 4.11. This study concludes that deep-breathing techniques are effective in reducing menstrual-related stress in female students within a single session and can be recommended as a complementary strategy that is easy to implement in schools for adolescent menstrual stress management.
