<p><em>Monosodium Glutamat activates an axis ablation in arcuate nucleus hypothalamus which happens to possibly initiate malfunctions in Hipothalamic Pituitary Adrenal axis. Yet, it is known that hypothalamus produces Gonadotropin Releasing Hormone which is able to stimulate the secretion of Gonadotropin Follicle Stimulating Hormon and Luteinizing Hormone from the anterior pituitary gland. These two hormones, however, are essentials for the development of gonad and during the cycles of oogenesis. Hence, any malfunctions resided in the human’s hypothalamus can possibly put endocrine gland into troubles, such as reproduction hormones which affect the workings of gonad. Therefore, the extract of Temulawak is promoted to be the attempt to resolve the issue for its antioxidant properties. Temulawak extract contains antioxidant, properties for as much as 87.01 ppm, according to Rosidi research’s result, analyzing the Temulawak’s potentials. The amount of antioxidant found Temulawak extract is categorized as active and applicable as natural antioxidant source. However, this research adopts true experimental post-test only control group design. It includes 5 (five) groups of female mice as which are K1 (CMC), K2 (CMC+MSG), P1 (MSG+0.4 mg Temulawak extract), P2 (MSG+0.8 MG Temulawak extract), P3 (MSG+1.2 mg Temulawak extract). In addition, the mice’s ovaries are removed to be subsequently tested using Hematoxillin-Eosin and the ovaries’ follicles quantity is observed and counted. The data is analyzed using One Way ANOVA. The research finally comes with a result showing that there are not any significant differences discovered from the ovaries’ follicles quantity from the five tested groups (p&gt;0.05). Therefore, it is implied that Temulawak extract does not provide any influential results to the house mice’s ovaries’ follicles quantity which has been exposed to MSG</em>.</p><p><em> </em></p><strong><em>Keywords</em></strong><em>: Monosodium Glutamate (MSG), Temulawak (Curcuma xanthorriza Roxb.), Ovarian follicles quantity </em>

Objective: Excessive use of MSG in everyday life can cause infertility to men. Exposure to MSG can cause cells to experience oxidative stress which subsequently triggers the generation of free radicals. Free radicals can be resisted with antioxidants. Material & Methods: This research was a laboratory experimental test with a post-test only control group design using male mice as the experimental object. The statistical test used the One Way ANOVA test. Results: In this research, 5 male mice were assigned into 4 groups and 1 control group. Using the One Way ANOVA test, it was found that there were significant differences in ≥ 2 treatment groups in the motility group of spermatozoa with active movement (p < 0.001) and the motility group of spermatozoa with weak movement (p = 0.036). The two groups showed significant differences. The Post hoc LSD test in the motility group with active movement showed significant differences between the control group with MSG treatment (p < 0.001) and the treatment group given Moringa leaves extract of 600 mg/kgW (p < 0.001) and 1200 mg/kgW (p < 0.001). Conclusion: Moringa leaves extract can effect the improvement of the motility of spermatozoa exposed to monosodium glutamate at a given dose of 300 mg/kgW and 600 mg/kgW.

Salah satu upaya untuk mengurangi kasus DBD adalah dengan pengendalian vektor DBD dengan larvisida. Temephos merupakan salah satu insektisida yang telah digunakan lebih dari 30 tahun dan berfungsi mengendalikan larva vektor. Penggunaan temephos yang tidak sesuai aturan dapat menyebabkan penurunan kerentanan pada vektor DBD.  Tujuan penelitian ini  adalah untuk  menilai  status  kerentanan larva Aedes aegypti di tiga kecamatan di Kota Padang. Penelitian ini menggunakan post  test  only  with  control  group design. Telur diambil dan dipelihara di laboratorium hingga mencapai larva instar III/IV. Uji kerentanan untuk temephos dilakukan berdasarkan standar WHO. Hasil penelitian menunjukkan pada Kecamatan Kuranji, kematian larva pada konsentrasi 0,005 mg/L sebesar 10%, 0,01 mg/L sebesar 45%, 0,02 mg/L sebesar 86%, dan pada konsentrasi 0,03 mg/L sebesar 100%. Pada Kecamatan Koto Tangah, kematian larva pada konsentrasi 0,005 mg/L sebesar 24%, 0,01 mg/L sebesar 48%, 0,02 mg/L sebesar 99%, dan pada konsentrasi 0,03 mg/L sebesar 100%. Pada Kecamatan Padang Timur pada konsentrasi 0,005 mg/L didapatkan kematian larva sebesar 12%, pada 0,01 mg/L sebesar 43%, pada 0,02 mg/L sebesar 99%, dan pada 0,03 mg/L sebesar 100%. Hasil uji One way-Anova adalah bermakna dengan nilai p<0,05 pada ketiga kecamatan dan LC99 sedikit diatas 0,02 mg/L. Simpulan penelitian ini adalah status kerentanan Aedes aegypti terhadap temephos di tiga kecamatan berkisar antara rentan dan toleran, belum mencapai resisten sehingga temephos masih dapat digunakan dalam pengendalian vektor DBD.

Pendidikan di sekolah membuat remaja dapat mengembangkan keterampilan sesuai dengan minat dan kemampuannya. Pendidikan tersebut hanya mengutamakan aspek fisik dan kognitif sehingga perlu disadari bahwa terdapat aspek psikososial yang hendaknya ditumbuhkan dalam proses pembelajaran yaitu self esteem. Self esteem adalah evaluasi yang dilakukan individu mengenai seberapa besar kepercayaan individu terhadap kemampuan, keberartian, kesuksesan dan keberhargaan, serta memainkan peran penting dalam memprediksi penyesuaian terhadap masa depan. Perkembangan self esteem pada remaja tidak terlepas dari lingkungan sosialnya, mulai dari orang tua, teman sebaya dan masyarakat sekitar serta guru di sekolah yang seringkali memberikan label pada remaja tersebut (Herlina, 2007). Pemberian label akan memunculkan stereotip, separation dan diskriminasi sehingga menjadi sebuah stigma. Crocker (2002) menyatakan stigma memiliki peranan terhadap self esteem. Penelitian ini merupakan penelitian kuantitatif dengan metode eksperimen yang menggunakan desain kuasi eksperimen nonequivalent control group design. Peneliti menyebarkan skala self esteem pre-test dan skala self esteem  post-test pada kelompok eksperimen dan kelompok kontrol yang terdiri dari 44 item, teknik pengambilan sampel menggunakan sampel jenuh. Responden dalam penelitian ini adalah remaja perempuan yang mengikuti ektrakurikuler tari Bali di SMAN 2 Denpasar, sebanyak 35 orang. Seluruh subjek dibagi menjadi tiga kelompok yang terdiri dari kelompok eksperimen 1, eksperimen 2 dan kelompok kontrol. Data yang diperoleh kemudian dianalisis dengan menggunakan one way anova. Hasil dari penelitian ini menunjukan probabilitas 0,003 (p)<0,05. Hal ini berarti ada pengaruh stigma terhadap self esteem remaja perempuan yang mengikuti ektrakurikuler tari Bali di SMAN 2 Denpasar. Stigma positif maupun stigma negatif berpengaruh negatif terhadap self esteem artinya baik stigma positif maupun stigma negatif membuat self esteem menurun pada remaja perempuan yang mengikuti ektrakurikuler tari Bali di SMAN 2 Denpasar. Berdasarkan hal tersebut dapat disimpulkan bahwa stigma memberikan pengaruh terhadap menurunnya self esteem remaja perempuan yang mengikuti ektrakurikuler tari Bali di SMAN 2 Denpasar.   Kata Kunci : Stigma, Self Esteem, Eksperimen, Remaja Perempuan
