Abstract: 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.

One of the uses of multimedia is to explain abstract concepts that cannot be directly observed by the five senses to be more easily understood, especially related to the concept of nuclear reactions in nuclear physics courses. This research aimed to get an overview of the mastery of the concept of nuclear reactions in students who take core physics courses and get an overview of the responses of students' perceptions of learning. The method of this research was experimental research with one group pretest-posttest design. Data collection techniques used in this research include the mastery test, student response questionnaire, documentation and observation. Data analysis techniques include descriptive analysis of student response questionnaires about multimedia-assisted nuclear physics learning process and analysis of mastery test results of the concept of nuclear reactions in nuclear physics courses using Ngain scores. The results showed that there was an increase in mastery of the nuclear reaction concept in nuclear physics subject with score of n-gain result was 0.41 and came into medium category. The ability to master concepts includes the ability to remember, understand, apply, analyze and evaluate. Based on this description, it can be concluded that the use of multimedia can increase students’ mastery concepts of nuclear reactions concept in nuclear physics courses.

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).

One of bio-indicator soil fertility is soil mesofauna. Soil mesofauna is soil organism that have an important role in distributing organic matter in the soil, improving soil physical properties, and increasing soil fertility. If there are more mesofauna in an area of land, the ecological conditions of the land have abundant organic material and have good soil conditions. The purpose of this study was to determine the types of mesofauna found in the soil around Arabica coffee plants. The method for capturing soil mesofauna was with a pitfall trap. The results of the identification of soil mesofauna in Arabica coffee plants on Kalibendo plantations were obtained by several species including the Order of Collembola and Subclass of Acarina. Species of the Order of Collembola was found Pseudoparonella sp., Salina celebensis, Isotomurus balteatus, Lobella sp., Hypogastrura purpurescens, and Sminthurides sp. Whereas from the subclass of Acarina was found the family of Ixodidae.

Abstract. Ethnomatematics as link between culture and mathematics is a multicultural mathematical activity that uses culture in making connections with mathematics topics so as to motivate students to preserve their own culture while learning mathematics. The purpose of this reasearch are to explore ethnomathematics in Gajah Oling’s batik based on geometric concepts. The type of reaserch is qualitative with an ethnographic approach. Data collection methods used are observation and interviews. The subject of this reasearch is a design maker Gajah Oling’s batik. This research focuses on intersesting discovery from the exploration results, that is making pattern of Gajah Oling’s batik shirt. In the process of making pattern of Gajah Oling’s shirt, ethnomathematics seen on design and measuring activities. In desiging activities geometric concepts such as translation and reflection emerge, while in measuring activities, design makers use mathematics to determine the design size so that the fabric meeded to make a shirt can be minimized as little as possible.Keywords: Ethnomatematics, cocoa farmers, culture. Keywords: Ethnomatematics, Gajah Oling’s Batik, Geometry
