Evaluation of Bacillus thuringiensis-based bioinsecticide impacts on arthropod biodiversity in the intercropping system Pujiastuti, Yulia Bacillus thuringiensis Cucurbitaceae Insect pests Natural enemies Vigna sinensis The intercropping system is intended to increase vegetable production. However, The presence of pests reducing production levels is a challenging constraint and should be controlled. In this study, Controlling insect pests will be evaluated by Bacillus thuringiensis-based bioinsecticide. The purpose of the research was to investigate the biodiversity of insect pests and their natural enemies in intercropping systems (cucumber and long beans), applied by B. thuringiensis-based bioinsecticide, chemical insecticide, and no-both application. Observation of existing insect-plant canopy was directly observed, and those on soil surface were observed by pitfall traps and yellow trays, as well. The research was performed in the experimental farm of the Sriwijaya University Faculty of Agriculture, Indralaya Campus, Ogan Ilir, South Sumatra, from July until October 2018. Results indicated three ecological roles of insects, namely predators/carnivores, pests/herbivores, and pollinators. Other insects and arthropods obtained from direct observation sampling method identified ten orders, but treatments of B. thuringiensis-based bioinsecticide resulted in 29 families of insects, chemical treatment was 17, and control (no treatment) was 32 families. B. thuringiensis-based bioinsecticides may be used in the intercropping system since it causes the highest biodiversity (H '= 2.96), high predator population (45%) and low pest population (41%) compared to other treatments.

Developmental the pattern of embryogenic microspore of rice (Oryza sativa L.) based on morphological characteristic Nurbaiti, Siti Purwestri, Yekti Asih Daryono, Budi Setiadi Semiarti, Endang Indrianto, Ari Development process embryogenic microspore morphological character rice Microspore culture is a rapid approach to get double haploid plants in shorten time which is important for plant breeding. Microspore culture of pigmented rice cultivar Segreng was used to observe the pattern of embryogenic development based on the characteristics of morphology. Characterization between embryogenic and non-embryogenic microspores was conducted after exposed anther to carbohydrate starvation in B medium culture at 33oC for 4 days. The result showed that enlarged microspore and star-like structure of fragmented cytoplasm become a marker of embryogenic microspore after stresses treatment. More complex of fragmented microspore was found at 4 days in A2 medium and developed further into multicellular structure. These multicellular structures might be originated either by symmetrical or asymmetrical division. The longer incubation, the higher frequency of complex fragmented microspore that developed into multicellular structure release from exine has appeared.

Profile of microbial community of naturally fermented Sumbawa mare’s milk using next-generation sequencing Jatmiko, Yoga Dwi Mustafa, Irfan Ardyati, Tri fermented mare’s milk high-throughput sequencing lactic acid bacteria metagenomic QIIME yeast This study aimed to investigate the bacterial and fungal/yeast diversity in naturally fermented Sumbawa mare’s milk through a next-generation sequencing approach, and evaluate the quality of fermented mare’s milk based on the presence of pathogenic or undesirable microorganisms. Microbial density determined using plate count agar (total aerobic bacteria), de Man Rogosa Sharpe agar (Lactobacillus), M17 agar (Lactococcus) and yeast peptone dextrose agar supplemented with streptomycin 50 ppm (yeast). Nutritional content and acidity level of each fermented milk sample were also evaluated. Genomic DNA was extracted using FastDNA Spin (MPBIO). The total gDNA was further analyzed using illumina high-throughput sequencing (paired-end reads), and the sequence results were analysed using QIIME v.1.9.1 to generate diversity profiles. The difference in nutrient content of mare’s milk was thought to affect the density and diversity of microbes that were able to grow. Fermented mare’s milk samples from Sumbawa had the highest bacterial diversity compared to samples from Bima and Dompu. However, fermented mare’s milk from Dompu had the best quality which was indicated by the absence of bacteria that have the potential to be pathogenic or food spoilage, such as members of the Enterobacteriaceae family (Enterobacter, Klebsiella and Escherichia-Shigella) and Pseudomonas. Genus of Kazachstania and Kluyveromyces, as well as family Dipodascaceae were frequently observed fungi/yeast from Sumbawa fermented mare’s milk. The presence of potential pathogenic bacteria warrants special attention in improving the hygiene of manufacturing process.

Seed storage importance and behaviour of a vulnerable species Angsana (Pterocarpus indicus Willd.) Rindyastuti, Ridesti Siahaan, Febrina Artauli Duration methods seed storage Pterocarpus indicus Angsana (Pterocarpus indicus Willd.) is one of woody plant species listed in the IUCN red list for priority in conservation as a vulnerable species. The effective and low-cost methods of seed storage is required to support the ex-situ conservation through seedling recruitments for population improvement. This study used completely randomized factorial design with 2 factors i.e. seed storage methods (room temperature, sealed jar and cold temperature), and storage duration (1,2,3,4 and 5 months). This study used 3 replications for each treatments and 10 seeds for each replication. The result showed that the seed of P. indicus start to germinate in 5-11 days after seeding while leaf emerged in 15-13 days after seeding. Seed viabilities generally were high until 3 months of storage (up to 65%) and start to decline at 4 months of storage at 51%. Storage methods and storage duration significantly influenced the seedling growth, viability, and Relative Growth Rate (RGR). There was an interaction between two factors. The storage at room temperature during a month (1RT) has the highest seedling height. The seeds stored in sealed jar during 5 months (5SJ) showed the highest seedling RGR, while the seeds stored in sealed jar during 3 months (3SJ) has the highest seed viability. For longer term storage, the seed of P. indicus should be stored in sealed jar or at room temperature at 11% moisture content. Both in the rainy and dry season, seedling recruitments were low and sapling stage was rare which showed low seedling establishment. Moreover, based on the phenological information, it is better to store the seed during the rainy season.

Effect of bait density on consumption rates and mortality of subterranean termite Coptotermes curvignathus Indrayani, Yuliati Fatmawati, Dewi Bait density consumption rates subterranean termites Coptotermes curvignathus termite control termite mortality Utilization of baits for controlling termites is achieving high attention in recent year. One of affecting factors of baiting preference of termites including the density of bait. In this study, the effect of bait density on consumption rates and mortality of subterranean termite Coptotermes curvignathus was investigated. Baits prepared by 1:1:1 weight ratio of mixed blended official waste paper, cardboards and cajuput (Melaleuca leucadendra) leaf which were formed into a cube measuring 2x2x1 cm. The baits density were 0.5, 0.6, 0.7, 0.75, 0.8, 1.0 gr/cm3. No choice and multiple choice tests were conducted with five replications. Clear plastics cup measuring diameter 6 cm and 12 cm were employed for no choice test and multiple choice tests respectively. Fifty workers and five soldiers of C. curvignathus were used for no choice test, while 150 workers and 15 soldiers were tested in the multiple choices test. The results indicated that bait with lower density had a better consumption rates to C. curvignathus. The influence of bait density on termite mortality was also reported, since there is a relationship between consumption rates and termite mortality which is contrary to the general toxicity test. The percentage of consumption rates was still lower therefore further research is indispensible on reformulation of the baits.

Biofilm formation and detection of A/D genes in MRSA (Methicillin-Resistant Staphylococcus aureus) and MSSA (Methicillin-Sensitive Staphylococcus aureus) Purbowati, Rini Biofilm ica A/D gene MRSA MSSA MRSA (Methicillin-Resistant Staphylococcus aureus) arises due to excessive use of methicillin antibiotics and complications from all medical practices that have been carried out lately. The prevalence of MRSA tends to increase and its ability to form biofilms so that it has the potential to significantly increase mortality and morbidity. Biofilms are considered one of the microbial virulence factors. Biofilm formation in S. aureus is regulated by the expression of PIA which mediates attachment between cells to cells and is a product of the ABDC ica gene. This study aims to determine the ability of biofilm formation as one of the virulence factors in MRSA compared to MSSA (Methicillin-Sensitive Staphylococcus aureus) . its relationship to the presence of A and D ica genes as biofilm coding genes. Biofilm formation assay on MRSA and MSSA using the Microtiter Plate (MtP) method and the A/D gene detection assay performed by PCR method. The results showed that the incubation end value of Optical Density (OD) for MSSA1 (0.75), MSSA2 (0.46), MRSA1 (0.53) isolates according to the formula were interpreted as moderate biofilm producer.  The conclusions of this study were all of the test isolates (MSSA1, MSSA2 and MRSA1) were able to form a biofilm. Distribution of ica A and ica D genes in MSSA 1 and MSSA 2 was varied while MRSA1 had the ica A and ica D genes.
