Abstract

Abstract: The majority of Indonesian coffee production is robusta coffee. The increasing coffee production with large scale causes changes in the soil ecosystem, it profitable for development of pest populations and diseases in coffee. One of pests that attack coffee plant is Pratylenchus coffeae. Rizosphere is ground around the roots measuring about 1 mm and surrounds entire surface of roots. Rizobacteria are beneficial bacteria that live in a saprophyte in a rhizosphere. This research aims to perform the isolation and identification of rhizobacteria from robusta coffee plants in Kali Bendo plantation, Banyuwangi Regency, East Java. In this research, the determination of research location is using purposive sampling technique, while the sampling technique is using random sampling method. The results showed there were 8 isolates obtained Bacillus sp. with isolate code 3R, G20, and I13, Micrococcus sp. with isolate code L20, Acinetobacter sp. with isolate code 4R and C13 and Pseudomonas sp. with isolate code M20 and A13. Key words: identification, rizobacteria, rizosphere

Abstract

Abztract: Azotobacter is one group of aerobic bacteria that colonizes root surfaces and is able to produce glyceroline promoting substances, cytokines and Indole Acetate Acid (IAA). Azotobacter can be found in the rhizosphere of various types of plants, such as soy rhizosphere (Glycinemax L.), rhizosphere palm (Elaeis guineensis), coffee (Coffea arabica), and corn (Zea mays). Rhizosphere is a soil zone that surrounds the roots of plants where biology and soil chemistry are affected by roots. This zone has a width of about 1 mm. In this study rhizosphere used is rhizosphere coffea Robusta plant. The purpose of this research is to know the isolated Azotobacter isolate from the rhiszosphere of Robusta coffee plant which attacked by Pratylenchus coffeae parasite parasite from Kalibendo plantation, Banyuwangi. The type of research used is explorative research. In this research successfully obtained 5 bacterial isolates. The result showed that from isolate isolate, 4 isolates were genus Azotobacter while 1 isolate was not known. Keyword: Azotobacter; Plant parasitic nematodes, Rhizosphere.

Abstract

Abstract: Granules extract of clime fruit (Citrus aurantifolia L.) is a biolarvasida in eradicating Aedes aegypti mosquito larvae L. Granules extract of lime fruit (Citrus aurantifolia L.) can kill mosquito larvae because its content of limonoida, tannin, flavonoid, and volatile oil. The compound is lethal to the larvae which will enter the body of the larvae of the Aedes aegypti L. mosquito which disrupts the systems in its body. The purpose of this article is to determine the safety of lime fruit (Citrus aurantifolia L.) extract granules on non-target animals, namely tadpoles. Tadpole has the same habitat with mosquito larvae so it is done safety test of citrus fruit extract granule (Citrus aurantifolia L.). Tadpole is a larval phase in Amphibi that continues to experience morphological development in water. The initial phase of tadpoles growth is a phase of adaptation to its habitat. Individuals who can not adapt well will experience a faster death. The research method used is laboratory experimental. The analysis used is ANOVA. The independent variables in this study were the variety of granules extract concentration of citrus fruit (Citrus aurantifolia L.). Tadpole mortality became the dependent variable in this study. Tadpole mortality is characterized by tadpoles collapsing at the time of administration of granules. The results showed that the lime extract granules (Citrus aurantifolia L.) proved safe. Keywords: Granules, Mortality, Tadpole

Abstract

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

Abstract: Bondowoso is one of regencies in East Java which is famous with cassava production. The abundance of the crop is caused by a very supportive natural condition. The abundance of cassava plants in Bondowoso Regency is really helpful to support the fulfillment needs of the community, especially the utilization as a traditional medicine that is trusted by the community as an alternative medicine that is easy and cheap also healthy. The research method used is direct observation with sampling using Purposive Sampling and Snowball Sampling. The results showed that there are 10 types of cassava plant utilization that has potential as medicine, including blood booster, infant massage, Astomach medication, sondhep medicine (angina/sitting wind), wound medicine, bone strengthening drink, bone fracture, travel ailment, kidney disease and stomach ailment. Keywords: Ethnobotany; Traditional Medicine; Cassava

Abstract

Abstract: Forest is a unit of ecosystem in the form of a stretch of land containing living natural resources dominated by trees and other natural components which cannot be separated. One of Indonesian forest that has high plant species richness, is the Raden Soerjo Forest Park. The place is also rich of lower plants species due to its dimatic and environmental condition. Lower plants consist of all types of vegetation which are found under forest stands except young trees. The group of lower plant is mostly bushy. Shrubs are layer of plants that grow clumped with short stems below 1.5 meters high. This study atmed to determine the diversity of shrub in Raden Soerjo Forest Park. This type of research is descriptive exploratory research. The result showed that are 23 species of shrubs in Raden Soerjo Forest Park, those 23 are belong to 15 classis which are Asteraceae, Rubiaceae, Gesneriaceae, Elaegnaceae, Primulaceae, Fabaceae, Polygonaceae, Acanthaceae, Urticaceae, Rutaceae, Malvaceae, chloranthaceae, Verbenaceae, Solanaceae, and Rosaceae. The result of diversity of shrubs in each family is Fabaceae (low), Malvaceae (low), Asteraceae (low), Verbenaceae (low), Urticaeae (low), Solanaceae (low), Rosaceae (low), Chloranthaceae (low), Polygonaceae (low), Elaegnaceae (low), Rutaceae (low), Primulaceae (low), Acanthaceae (low), Gesneriaceae (low), dan Rubiaceae (low). The total number of plants found is 213 plants. Keywords: Forest, Diversity,Raden Soerjo Grand Forest Park, Shurb

Abstract

Sugarcane is one of the plantation products in the Jember area. Therefore, the processing of sugar cane as renewable energy can be used as a source of learning. The purpose of this research was to describe and analyze student responses profile by using teaching materials about the utilization of sugarcane processing as renewable energy in physics learning. This research method was descriptive research. The research respondents were 30 students who took integrated science course in odd semester 2016/2017 at the Physics Education Study Program, University of Jember. Data collection techniques using student response questionnaires, observation and documentation. Data analysis techniques use percentages. The results of this research indicate that student responses to the use of teaching materials about the utilization of sugarcane processing as renewable energy in physics learning amounted to 83,87% with a very positive category. Based on the analysis, it can be seen that students gave a very positive response using teaching materials about sugarcane processing as renewable energy in physics learning. Thus, the using of teaching materials about sugarcane processing as renewable energy can improve student learning motivation, mastery of concepts, scientific attitudes and environmental awareness.
