Abstract

Pupuk ZA merupakan pupuk anorganik yang mengandung nitrogen dan sulfur. Nitrogen merupakan unsur hara utama pada pertumbuhan tanaman yang merupakan penyusun protein, sedangkan sulfur merupakan penyusun 21 asamamino pembentuk protein. Protein dibutuhkan oleh Bombyx mori L. untuk metabolisme dalam tubuhnya serta untuk pembentukan kokon. Tujuan penelitian ini yaitu untuk mengetahui pengaruh pemberian pupuk ZA pada tanamanmurbei terhadap kokon ulat sutera alam (B. mori). Tanaman murbei yang diberi perlakuan pupuk ZA berumur 1 bulan dari penanaman, dan digunakan sebagai pakan setelah berumur 3 bulan dari penanaman. Jenis penelitian ini yaitu deskriptif kuantitatif. Hasil penelitian menunjukkan terdapat pengaruh tanaman murbei yang diberi pupuk ZA terhadap berat kokon (F=8,767, p=0,000) dan diameter kokon (F=2,914, p=0,036). Rerata berat kokon tertinggi yaitu pada P3 (18,75 g/polybag) dengan rerata 1,91 g. Rerata diameter kokon tertinggi pada P3 (18,75 g/polybag) dengan rerata 2,08 cm.

Abstract

Penyakit jantung koroner (PJK) terutama disebabkan oleh aterosklerosis karena hiperkolesterolimia. Oksidasi low density lipoprotein (LDL) oleh reactive oxygen species (ROS) sebagai penyebab utama proses aterogenik dapat dicegah dengan kehadiran antioksidan seperti vitamin E. Buah dan sayuran banyak mengandung vitamin. Salah satu buah yang mengandung vitamin E adalah buah merah (Pandanus conoideus Lam.). Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak buah merah terhadap kadar LDL darah pada tikus putih (Rattus norvegicus L.). Jenis penelitian ini adalah penelitian eksperimental laboratorium yang didesain mengikuti Rancangan Acak Lengkap (RAL) dengan 6 perlakuan dan 4 kali ulangan dengan parameter penelitian adalah kadar LDL darah tikus putih. Data dianalisis menggunakan one way anova dilanjutkan dengan uji Duncan 95%. Berdasarkan hasil penelitian, minyak buah merah memiliki kemampuan untuk menurunkan kadar LDL darah tikus putih.

Abstract

Synthetic estrogen hormone that has known by the public is an estrogen that is contained in hormonal contraception or birth control pills. The lack of public knowledge about the action mechanism of oral contraception on the reproductive organs makes people ignoring about the impact of it. This study was conducted to analyze the differences in the induction of estrogen towards the levels of estradiol and histology of the uterus and its utilization as a supplement book of Reproductive System topic in high school. Balb-C female mices were used as the tested animals and Microgynon, the contraceptive pill’s trademark was used as a source of estrogen induces. Blood samples were taken at pro-estrus phase, while the uterus was taken at each phase of the estrous cycle. Measurement of estradiol levels was done by ELISA method, whereas the thickness of endometrium is determined on a longitudinal incision of the uterus by the method of preparation of histological paraffin and HE staining. The supplement book was arranged refers to 4-D models. The results showed that there was a difference between the levels of estradiol-induced estrogen treatment with control, but in endometrial thickness among the control treatment with estrogen did not show the differences significantly. The results also showed that the estrogen induction has no significant effect on endometrium thickness at each phases of estrous cycle. The results of research were used as supplement book and it can be used for enriching knowledge of reproductive topic on high school.

Abstract

Students in the agroecosystem area have self-motivation to follow low learning which causes their learning outcomes lower. It can be increased by applying Brain-Based Learning (BBL) approach combined with Send A-Problem (SAP) collaborative learning model. This is a development research using 4-D model. Only 3 stages were chosen; define, design, and develop. The research aims to produce a valid, practical and effective SAP based on BBL to increase students' metacognitive awareness and learning outcomes. The average of product validation is 88 (very valid category). The average percentage of students' metacognitive awareness was 66.31 (developing category) before the application and 85.85 (very good category) after the application of the learning. Normalized gain analysis result is 0.62 referred to medium category, which means that there is an increase in student learning outcomes. The average percentage of student (84.33%) and teacher responses (98%) is included in the very practical category.

Abstract: Utilization of earthworms (Pheretima javanica K.) other than as a soil fertilizing organism is an alternative treatment for typhoid fever as a traditional medicine and provided in the form of whole powder. This study was conducted to determine the toxicity effects of earthworm powder on kidneys in white rats (Rattus norvegicus). Total of 50 white rats were divided into five groups consisting of negative control (2 ml CMC Na 1%), group P1 0,4 grams, group P2 0,8 grams, P3 group 1.6 grams, and P4 group 3.2 grams of dry earthworm powder. White mice were then acclimated for approximately one week and induced with dry earthworm powder orally. The study was conducted for 14 days to see the description of the toxic effects caused. The results of data analysis using ANOVA showed that each dose of dry earthworm powder had no effect on kidney function of white rats (Rattus norvegicus). Keywords: Pheretima javanica K.; Rattus norvegicus; kidney function

Abstract: Meru Betiri National park has a region part, it’s reference zone and rehabilitation zone. Referensi zone is a conservation area that have to protect from damage by human interference to protect flora, fauna and other environmental component for importance of next generation. Rehabilitation zone was damaged without original vegetation and be a seasonal land farm. Termites is a important part of insect in material recycling of plant trhough disintegration process. The aim of the research are to knowing types of termites and to knowing the different of termites diversity in referensi zone and rehabilitation zone Meru Betiri National Park. Research methods by used direct sampling. The result of research has get 2 species founded, that’s Macrotermes gilvus Hagen (mayor), Macrotermes gilvus Hagen (minor) and Nasutitermes metangensis with totally 194 individual. Index of species diversity (H’) in the reference zone = 0, it's caused there are only one species founded and index of species diversity (H’) in rehabilitation zone = 1,036. It can be concluded that diversity of species on both has a different level diversity although same on low diversity. Kata Kunci: Indeks Keanekaragaman Spesies; Taman Nasional Meru Betiri; Rayap.
