Abstract - The development of the plantation sector has increased impact of which waste wood sawdust and cocoa fruit peel. These wastes can cause environmental problems if not treated, but they would be beneficial if they are used as growing media mixture in oyster mushroom cultivation. Growing media (baglog) oyster mushrooms are supported physically and chemically will affect the productivity and nutrient content of oyster mushrooms. The study aims to analyze and assess the effect of the cocoa fruit peel waste as  growing media mixture on productivity and nutrient content of brown oyster mushroom (Pleurotus cystidiosus) that has been carried out using a completely randomized design (CRD) with 4 kinds of treatment comparisons sawdust and fruit peel waste cocoa, ie SL0(ratio of 100% wood sawdust and 0% fruit peel waste cocoa)/control, SL1 (ratio of 80% sawdust and 20% fruit peel waste cocoa), SL2 (ratio of 75% sawdust and 25% fruit peel waste cocoa) and SL3 (ratio of 70% sawdust and 30% fruit peel waste cocoa). The research data in the forms of number and weight of fruit body production, as well as protein and fat content of brown oyster mushrooms, were then analyzed by one-way anova and followed by DMRT (Duncan Multiple Range Test)  at 5%. The results showed that the use of cacao fruit peel waste by ratio comparison  75% wood sawdust and 25% cacao fruit peel (SL2) is the best to produce the number and weight of fruit body production as well as protein and fat content of brown oyster mushrooms. Therefore, it is recommended to be applied in the cultivation of brown oyster mushroom. Keywords: wood sawdust , growing media, productivity, nutrition, brown mushrooms

Abstract

Abstract Students in the agroecosystem area are generally less active because the teacher does not utilize the potential of the surrounding agroecosystem. This can be overcome by applying Brain-Based Learning (BBL) approach combined with AT collaborative learning model. This study aimed to produce Analytic Team learning model based on Brain-Based Leaning (AT-BBL) that is valid, practical, and effective, and also improves the students' critical thinking skills and learning outcomes. This study used R&D with 4D development model which only carried out three stages, namely define, design, and development without using the disseminate stage. The average validation is 86.98 (highly valid). The average percentage of teacher responses is 92.94%, and the average percentage of student responses is 91.22% which is very practical. Keywords: Agroecosystem, BBL approach, Analytic Team Learning Model, Collaborative Learning

Abstract

Leaves are an important organ for plants. One part of leaf is stomata which function as a place for gas exchange. The method used in this research is the observation of the morphology and anatomy of frangipani leaves (Plumeria acuminata) which are exposed to pollution and not exposed to pollution. The purpose of this study was to determine environmental conditions or as a bioindicator by observing damage to plants. Macroscopic damage to plants in leaf morphology and microscopic damage to changes in leaf stomata conditions. Observations show that the morphology of frangipani leaves (Plumeria acuminata) which are not exposed to pollution is larger than frangipani leaves (Plumeria acuminata) which are exposed to pollution. The number of stomata in the abaxial part is more than the adaxial part. Meanwhile, the number of stomata on frangipani leaves (Plumeria acuminata) that were not exposed to pollution was more than those exposed to pollution. The stomata type on frangipani leaves (Plumeria acuminata) is anomocytic type with kidney-shaped covering cells.

Abstract

Biology is a science whose concept is abstract and has a wide scope. One of them is the subject of Plantae that requires appropriate media to help to visualize the material being taught. Some things to consider in the selection of media such as material and learner characteristics. Characteristics of learners today is known as the Z generation so that the appropriate media is one that involves the use of technology. One of them is Edmodo-based e-learning media. The use of Edmodo-based e-learning media enables the delivery of more varied and much-involved students. This study aimed to find out the development process of Edmodo-based e-learning media and to produce a valid product as well as to know the effectiveness and practicality of the product. This research was a development research using a method by Borg and Gall (1983) model that has been modified by Sugiyono (2006). Stage of limited scale trial was conducted in SMAN 2 Jember and SMAN 4 Jember. The result of the product validation test of e-learning media development on average produced a valid product. Effectiveness test at SMAN 2 Jember and at SMAN 4 Jember resulted in a high N-Gain score. The result of the practicality test through the students and teachers responses of SMAN 2 Jember and SMAN 4 Jember created a response with strongly agree category. Keywords: Edmodo, e-learning, development, Plantae subject.

Abstract

The coffee nursery is susceptible to endoparasitic Pratylenchus coffeae. Application of biological method in the nursery is suggested to control the nematode population and maintain the seedling health. The objectives of this study were to observe the ability of Arbuscular Mycorrhiza Fungi (AMF) Glomus spp. and liquid inoculant of Mycorrhiza Helper Bacteria (MHB) consortium Pseudomonas diminuta and Bacillus subtilis for increasing AMF colonization and reducing the infection P. coffeae in Arabica coffee seedling and their growth. A pot experiment was conducted using a Completely Randomized Block Design with four treatments and five replications. The treatments were Glomus spp. spore inoculation without and with two concentrations of MHB. The control treatment did not receive Glomus spp. and MHB. The seedlings were growing in the greenhouse for three months. The results indicated that Glomus spp. and MHB consortium significantly reduced the nematode total number in soil and roots by approximately 30%; and infection degree of P. coffeae by 50%. The application of Glomus spp. significantly increased root colonization by mycorrhizal fungi, but MHB inoculation did not affect the mycorrhizal colonization. Seedlings treated with MHB had higher shoot length compared to the plant without MHB and control; but the leaves number and shoot dry weight of seedlings were not affected by all treatments. Even though the root fresh weight was reduced after MHB treatment, the lateral roots growth of MHB-treated seedling visually was improved. The experiment demonstrated that MHB was efficient to reduce P. coffeae infection of Arabica seedling.

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

In indonesia, infection diseases are a very high problem among the public, one the common infectious diseases suffered by the Indonesian community is imflamtion of the tonsils caused by Streptococcus pyogenesis and Cholera caused by Vibrio cholera. The use of chemical antibiotics will have a negative impact in health, so necessary alternative replecement of natural antibiotics by Serratia mercescens can pruduce prodigiosin. This reseacrh was to test the potential of Serratia mercescens antagonist against Streptococcus phyogenesis and Vibrio cholera in vitro, using Completely Randomized Design with one treatment factor from Serratia mercescens bacteria concentration. The concentration used was 30μm for each bacterial suspension and added positive control in the form of chloramphenicol and negative control of aquades, each of which was repeated 3 repititions. The results were analyzed using one-way ANOVA and continued D- test. The result showed that Serratia mercescens had blocked inhibitability of Streptococcus phyogenesis bacteria with an average resistance of1.1033mm and on Vibrio cholera with an average resistance of 1.2233mm.
