Abstract: This study aims to reveal the perceptions and needs of pre-service biology teachers on biotechnology learning and their need for instructional media, especially on the topic of basic molecular biology techniques. This descriptive quantitative study was done purposively on 42 students who have completed the biotechnology lectures in Biology Education Program, Universitas Negeri Malang. The data collection instruments consisted of a biotechnology topic difficulty survey questionnaire and a felt needs questionnaire. The questionnaire response data analyzed using descriptive statistics showed that students perceived the laboratory activity of basic molecular biology techniques as a moderate level. On average, all students performed DNA analysis techniques, and only 55% of all students performed protein analysis techniques. Overall, students have feelings, understanding, and confidence at a moderate level, while they feel they have excellent learning assistance. Even so, students feel they need learning resources in the form of research-based multimedia to support learning on the topic of practicum on molecular biology analysis techniques, especially in protein analysis techniques. Research-based protein analysis techniques multimedia that is suitable for students' university cognitive development are considered to be developed in supporting biotechnology learning for pre-service biology teachers.Abstrak: Penelitian ini bertujuan untuk mengungkapkan persepsi dan kebutuhan calon guru biologi terhadap pembelajaran bioteknologi dan kebutuhan mereka akan media pembelajaran khususnya pada topik teknik dasar biologi molekuler.

Tarakan sea waters have geographical circumstances and landscapes that supported the existence richness of fishes that abundant and diverse. There is local fish called Pepija or Lembe-Lembe, but biological studies on this fish most poorly known. This research is aimed to identify the morphological characters of Nomei (Harpodon sp.). Based on specific caharcter, morphometric, and meristric characters. Morphometrics analysis can be used to clustering and understanding relationship of taxa. Each species represented 10% samples of male and female from each type we found and measured 35 characters (in mm). The canonical, clustering and similarity were used. Based on determinant morphological characters species (pectoral fin length reaches or exceeds the initial dorsal fin, dorsal fin earlier than ventral fins), dendogram morphological characters, meristic characters, PCA grouping proved that Nomei fish from Amal and Juata as Harpo-don nehereus.

Dynamics of compound 1,3-Î²-glucan in Agaricus Blazei Murill (ABM) powder and the effect of renal and hepatic histopathology performed on 24 male rats aged 2 months, were randomly conducted in three treatments there are control, ABM powder, and the pure compound 1.3-Î²-glucan for 28 days. Provision of treatment given in the morning and then 1, 3, 8, 12, and 24 hours after administration of treatment blood was collected, while for urine and feces were collected every 8 hours. Giving treatment was continued until day 28. The results showed that the levels of 1,3-Î²-glucan in pure compounds is higher than the Agaricus Blazei Murill (ABM) powder. The effects on the kidneys and liver histopathology showed that cells necrosis more on pure compounds from the mushroom powder gods, both the kidneys and liver. This study shows that the use of pure compounds to be more careful than Agaricus Blazei Murill (ABM) powder in determining the doses used.

Daidzein compounds dynamic and the effect of yam tuber (Pachyrhizus erosus (L)) Urb on myometrium rats model of estrogenic were investigated. Twentyfour of 5 months-old female Sprague Dawley rats were randomly assigned to three groups as followed, control, Daidzein administraton and yam tuber juice administration for 24 days. The administration of yam tuber juice were given by orally using a stomach with gavage tube in the morning. Every 8 h, the rats blood and urine were collected from tail until 24 h. The treatment were continued until 24 days. The result showed that the level of daidzein in blood and urine of rats that administratered by Yam tuber juice is lower than pure daidzein treatment rats every 8 until 24 hours of collection. The results demonstrated that the administration of yam tuber juice significantly myometrium proliferated in rats. It is assumed that genistein and quercetin is estrogenic as found in daidzein so that the miometrium is potentially more effecctive. This study suggest that phytoestrogen compound from Pachyrhizus erosus may offer a potential as natural estrogenic in women.

The nutritional content of kian marine worm has never been reported. This study aimed to profile the nutritional content of worms from the Kei Islands, Maluku. Nutritional profiles were tested by proximate assays, atomic absorption spectroscopy (AAS), and High-Performance Liquid Chromatography (HPLC) of amino acids. The proximate analysis resulted in 71.16% of protein, 12.05% of water, 2.63% of carbohydrates, 2.21% of fat, 2.14% of crude fiber and 0.44% of ash. Mineral contents of Kian marine worm were 785.28 mg/kg potassium, 585.14 mg/kg magnesium, 180.98 mg/kg calcium, 0.89 mg/kg sodium and 0.44 mg/kg phosphorus. Kian marine worms contained 9 essential amino acids and 11 essential amino acids with levels of essential amino acids up to 206.94 mg/g and non-essential amino acids was 233.21 mg/g. Nutritional content in kian marine worms can be used as a potential high protein food resource.
