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.

Abstract

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

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.

Abstract

Giving mycorrhiza + MHB with goat manure to cocoa seeds to increase cocoa growth. The purpose of this study was to examine the effect of mycorrhiza + MHB combination with goat manure on cocoa seed growth (Theobroma cacao L.). This research used Factorial Randomized Complete Random Design (RAL) with two factors ie first factor of mycorrhizal + MHB with three levels of 0 g (m0), 7.5 g (m1), and 12.5 g (m2), the second factor goat manure with three taragos 0 g (k0), 100 g (k1), and 200 g (m2), and combination factors m0k0, m0k1, m0k2, m1k1, m1k2, m2k2, m2k0, m2k1, and m2k2 . The data obtained were analyzed using Anova and Duncan's advanced test. From the results of this study can be concluded that giving mycorrhiza + MHB with goat manure significantly influence the growth of cocoa seedlings (Theobroma cacao L.). Treatment with 7.5 g of mycorrhiza + MHB with 200 g of goat manure showed the best results on the growth of cocoa seeds compared with other treatments

Abstract

This research aimed at improving biology literacy ability based on HOTS (Higher Order Thinking Skill) by using E-pocket book learning media. This research employed a research and development (R&D) method, which was used as actual proof in improving a learning media of HOTS-based E-pocket book. There were 10 schools, including state or private schools, and 10 biology teachers as need analysis involved in this study. A needs assessment was conducted by using a questionnaire generated in Google form. The result of the needs assessment showed that teachers understood the HOTS learning process of 90%, HOTS learning material of 80%, and the teachers’ knowledge on E-pocket book learning media of 50%. Therefore, all of the teachers (100%) agreed if E-pocket book learning media is implemented for the students and if the learning media that can improve the students’ biology literacy should be developed.
