PENINGKATAN HASIL BELAJAR SISWA MATERI KELILING DAN LUAS SEGITIGA DENGAN METODE INKUIRI
Full text linkAbstract: In delivering subject material, teacher usually uses lecture method. Impact of this problem is less satisfactory student learning outcomes, indicated by amount of students who get score below Minimum Completeness Criteria, which is 70. The purpose of this research was to find students learning outcomes. A total of 38 students were involved in this study using Classroom Action Research (CAR) method which carried out in 2 cycles. Instument that used are test instrument and observation paper. Data analysis technique used in this research is Comparative Descriptive, by comparing data of learning outcomes in cycle I and cycle II. Based on test result in the first cycle, the average value is 69.86 with classical percentage of 66.67% with 12 of 36 students who had not completed their studies, in second cycle the average value is 80.56 with classical percentage 88.89% with 4 of 36 students who had not completed their studies.

ISOLASI DAN IDENTIFIKASI Azotobacter DARI RHIZOSFER TANAMAN KOPI (Coffea canephora) YANG TERSERANG NEMATODA PARASIT Pratylenchus coffeae
Full text linkAbztract: 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.

PENGARUH KOMBINASI BAKTERI ENDOFIT TERHADAP PERTUMBUHAN KOPI ARABIKA (Coffeae arabica L.) YANG TERSERANG Pratyenchus coffeae
Full text linkAbstract: Endophytic bacteria are the most preferred biological agents in the last period to control Pratylenchus coffeae parasitic nematodes in coffee plants Endophytic bacteria are able to control P. coffeae and increase plant growth. The results of the application of endophytic bacteria can be increased through a combination application. This study aims to determine the effect of a combination of endophytic bacterial isolates isolated from a coffee plantation from Kalibendo garden on the growth of Arabica coffee seedlings attacked by P. coffeae nematode. The study used isolates of endocytic bacteria Micrococcus luteus, Micrococcus sp. and Bacillus sp. the density of 109 cfu in two-month Arabica coffee plant seeds with 9 treatments, 4 replications and 3 sub-replication for 4 months of research. The results showed that a combination of endophytic bacterial isolates was able to significantly increase the growth of Arabica coffee plant seeds.

ISOLASI DAN IDENTIFIKASI RIZOBAKTERI DARI TANAMAN KOPI ROBUSTA (Coffea canephora) YANG TERSERANG Prattylenchus coffeae
Full text linkAbstract: 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.

IDENTIFIKASI SPESIES RAYAP PADA ZONA REFERENSI DAN ZONA REHABILITASI TAMAN NASIONAL MERU BETIRI
Full text linkAbstract: 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.

Full text linkAbstract: 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).

PENGARUH REBUSAN DAUN SALAM (Syzygium polyanthum Wight) TERHADAP PENURUNAN KADAR ASAM URAT DALAM DARAH MENCIT (Mus musculus L.) JANTAN Strain Balb-C
Full text linkAbstract: Uric acid is the final substance of purine breakdown which is assisted by guanase and xanthine oxidase enzymes. Excess blood uric acid levels are called hyperurosemia. Treatment is usually using synthetic drugs such as allopurinol which has side effects for the body, so it is necessary to take herbal remedies such as Syzygium polyanthum Wight which contains active ingredients such as flavonoids as an inhibitor of the xanthine oxidase enzyme. This study aims to determine the effect of giving Salam Leaf Decoction to the Decrease in Blood Uric Acid Levels. This study uses a completely randomized design study (CRD) with 5 repetitions. This study uses One Way Anova data analysis and continued with Duncan's Test. From the results of the study, at a dose of P1 (0.2 ml / 20 g WB), P2 (0.4 ml / 20 g WB) and P3 (0.8 ml / 20 g BB), a percentage of uric acid levels decreased 40.45% in group P1; 48.19% in the P2 group; 53.53% in the P3 group; 60.35% in the K + group; and -30.73% in the K-group. Of the 5 doses, the most effective dose to reduce uric acid levels in the blood is P2 dose (0.4 ml / 20g WB).
