Ketahanan berolahraga menunjang latihan fisik yang optimal untuk meningkatkan derajat kesehatan dan kebugaran jasmani. Penurunan kapasitas ketahanan olahraga disebabkan oleh dehidrasi dan penurunan karbohidrat dalam otot selama melakukan latihan. Air kelapa berpotensi sebagai minuman olahraga karena memiliki derajat keasaman yang rendah, gula seimbang, kandungan mineral, dan bersifat isotonis. Penelitian ini bertujuan mengetahui efek konsumsi air kelapa terhadap ketahanan dan kebugaran berolahraga diukur dari jarak tempuh dan VO 2 max selama latihan lari. Penelitian dilakukan di Lapangan FPOK UPI Bandung periode Juli 2015-Februari 2016. Bahan penelitian yang digunakan adalah air kelapa dalam kemasan. Air mineral, air gula 5%, dan minuman olahraga isotonik yang digunakan sebagai pembanding. Subjek penelitian adalah 120 orang laki-laki, berusia 18-23 tahun yang dibagi menjadi 4 kelompok untuk tiap-tiap bahan uji. Setelah pemanasan, subjek berlari secepatnya selama 30 menit. Bahan uji diberikan sebelum dan setiap 10 menit selama lari. Jarak yang ditempuh dicatat dalam satuan meter. Analisis dengan one-way ANOVA yang dilanjutkan dengan uji least significant difference (LSD) dengan α<0,05. Jarak tempuh terpanjang rata-rata dan VO 2 max tertinggi didapatkan pada kelompok perlakuan air kelapa, diikuti kelompok air gula 5%, minuman olahraga isotonik, dan air mineral (p<0,01). Simpulan, konsumsi air kelapa sebelum dan selama latihan olahraga lari dapat meningkatkan ketahanan olahraga pada laki-laki dewasa bukan atlet.

Classical and jazz music activates ? brain wave that stimulate the excretion of ?-endorphins that has a role in increasing the alertness and attention. The purpose of this study was to determine the effect of classical and jazz background-music to the concentration and reading comprehension. This is a quasi experimental study, with pre-test and post-test design, performed on 30 young adult women. The measured data were Addition and reading comprehension test scores before and while listening to music. Data were analyzed using paired t-test with and non paired t-test with ?=0.05. The results showed that there were highly significant differences of Addition Test score (547.73) and reading comprehension test score (80.33) with classical music background; Addition Test score (577.47) and reading comprehension test score (78.33) with jazz music background compared to pre-treatment of classical (457.57; 61.67) (p<0.01); and jazz music (538.07; 65.00) (p<0.01) respectively. The comparison of both types of music showed no difference of Addition Test score and reading comprehension test score (p>0.05). We concluded classical and jazz background music improve concentration and reading comprehension in young adult women, with no significant differences in both types of background music. Keywords: concentration, reading comprehension, background music, classical, jazz

Domestic chicken eggshells contain calcium and protein that could be useful in wound healing process. This research was conducted to determine whether domestic chicken eggshells can accelerate wound healing. Twenty one male Swiss-Webster mice  with 2 cm incision were divided into 3 groups. Negative control group were given Carboxymethyl cellulose 1% (CMC), positive control group were given feracrylum 1% (FER), and the eggshells group given domestic chicken eggshells powder (KT). Treatment and data mesurement was measured every day until  the 7th day. On the 7th  day the average length of the wound were analyzed and the skin tissue is taken for microscopic examination. Data analyzed using one-way ANOVA followed by Post Hoc Least Significant Difference (LSD) with p=0,05. On macroscopic examination, there were  highly significant differences between KT compared to CMC and highly significant differences between KT compared to FER. the average length of wound on the 7th day on KT 0,63 cm shorter than CMC 1,07 (p=0,000) and FER 0,81 cm (p=0,003). On microscopic examination, the degree of reepithelization on KT groups are severe, moderate for collagen density, fibroblasts density, subepithelial neutrophil density, degree of edema, and mild for angiogenesis. We conclude domestic chicken eggshells powder can accelerate wound healing. Key words: domestic chicken eggshells, incision wound, wound healing
