Abstract

The purpose of this study was to decide whether the mixture of KNO3 and GA3 solutions was more effective than a single solution of KNO3 or GA3 in maintaining the freshness of cut flowers. The study was conducted at the Botanical Laboratory of the Department of Biology, Faculty of Mathematics and Natural Sciences, University of Lampung from November - December 2017. The research was carried out in a 2 x 3 factorial experiment with reason A was the GA3 solution with 3 concentration levels: 0%, 0.5%, and 1%. Factor B is KNO3 solution with 2 concentration levels: 0% and 5%. The limits in this study were fresh weight, dry weight, relative water content, and total dissolved carbohydrate content of gerbera cut flowers, qualitative limits were the level of reducing sugars. Measurements were made 7 days after soaking cut flowers in KNO3 or GA3 solutions, and a mixture of both. Homogeneity of variance and analysis of variance were determined at a significant level of 5%. Simple effect of KNO3 at each concentration level of GA3 decide by F test at 5% significance level. The results showed that GA3 with a concentration of 0.25% and 0.5% increased the fresh weight and dry weight of Gerbera cut flowers. KNO3 0.5% much reduced the relative water content of Gerbera cut flowers. The interaction between GA3 and KNO3 does not much effect all freshness of cut flowers. From the results of the study concluded that the single treatment of GA3 was more effective than the combination treatment of GA3 and KNO3 in maintaining the freshness of Gerbera cut flowers.

Abstract

The ginger rhizome contains antioxidants and is chemoprotective, therefore we suspect it can decrease the aging rate in the reproductive system. The purpose of this study, to determine the effect of ginger extract (Zingiber officinale) against reproductive aging of male mice (Mus musculus). This study, using 36 male mice (Mus musculus) aged 12-14 months, divided into three groups each 12 tails. Group 1 as controls, groups 2 and 3 were given 50 mg and 100 mg ginger extract / kg of pellets. The pellet is given for 70 days ad libitum. Next, observed the number of spermatogenic cells, as well as the number and quality of spermatozoa. The results showed that ginger extract had an effect on spermatogenic and spermatozoa (P <0,01) cells of mice. The results of preleptotene spermatocyte, pakhiten and spermatid spermatocyte counts were higher, as were the number of spermatozoa, the percentage of viability and motility, and the normal morphology of spermatozoa were more in the group given ginger extract than control (P <0.01). It was concluded that ginger rhizome extract given to mice entering the aging period could inhibit the rate of decline in reproductive function.

Abstract

Paraquat is one of the chemicals that contributes to increasing pollution Indonesia. The careless use of paraquat can increase production of ROS (Reactive Oxygen Species), resulting in damage to a wide range of vital organs and reproductive system disorders such as infertility. ROS in the body can be captured by antioxidants. Red Ginger contains high antioxidants because there are active phenolic compounds such as gingerol, shagaol, zingeron, ginggerdiol, and zingibren which are proven to protect body cells from damage caused by ROS. This study was aimed to test the effectiveness of red ginger extract (Zingiber officinale Roxb. Var. Rubrum) on the quantity and quality of sperm in male mice (Mus musculus L.) induced by paraquat dichloride.This research uses a completely randomized design and is divided into six treatment groups with each four replications: K1 as the control group (only given H2O); K2 (paraquat induced a dose of 20 mg/kg Body Weight (BW) without the administration of the test substances); K3; K4; K5 (paraquat induced a dose of 20 mg/kg Body Weight (BW) and was given a red ginger extract at a dose of consecutive succession 6 mg / ml, 12 mg / ml, 18 mg / ml) and K6 (Only given a test material the red ginger extract as much as 18 mg / ml). Paraquat was given 2 times a week for 21 days and the red ginger extract was given for 35 days. The results of analysis by One-way ANOVA followed LSD at 5% significance level showed the ethanolic extract of red ginger can increase the sperm count, motility, viability and Morphology sperm of mice induced by the paraquat diklorida.

Abstract

Kumbang Tenebrio molitor atau yang lebih dikenal sebagai ulat hongkong, memiliki nilai ekonomis karena dapat digunakan sebagai pakan ternak maupun obat bagi manusia dan mudah dibudidayakan. Ulat hongkong belum dimanfaatkan secara maksimal, sementara ulat hongkong secara alami memiliki manfaat yang besar sebagai pengurai senyawa organik dan anorganik di alam, dari penelitian terakhir diketahui dapat mengurai styrofoam. Penelitian ini dilaksanakan pada Juli-Agustus 2016 di Laboratorium Zoologi Jurusan Biologi Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Lampung dengan tujuan untuk mengetahui kemampuan berbagai tingkatan stadium larva ulat hongkong dalam mengkonsumsi styrofoam. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL), dengan 10 instar larva ulat hongkong sebagai perlakuan dan 3 kali pengulangan. Data yang diperoleh dianalisis menggunakan Analisis Ragam (ANARA) dan dilanjutkan uji BNT (Beda Nyata Terkecil) pada taraf beda nyata 5% serta dilakukan analisis korelasi antara jumlah styrofoam yang dimakan dengan berat serta panjang ulat hongkong. Hasil analisis ragam menunjukkan bahwa pakan styrofoam mempengaruhi berat dan panjang ulat hongkong, serta lama stadium ulat hongkong (p < 0,05). Hasil analisis korelasi antara berat ulat hongkong dan jumlah pakan yang dimakan menunjukan adanya hubungan positif yang sangat kuat (r = 0,96), dan pada korelasi antara panjang ulat hongkong dan jumlah pakan yang dimakan menunjukkan adanya hubungan postif yang kuat (r = 0,66).
