One of the Robusta coffee producing areas in South Sumatera is South Ogan Komering Ulu Regency and it has an area of 70,799 hectares which is spread across 11 sub-districts. This study aims to assess the level of hygiene and sanitation in post-harvest coffee processing, and it was conducted through direct surveys at harvest time and by interviews and questionnaires. Sampling was carried out deliberately, on 30 coffee farmers spread across eleven villages in BPR Ranau Tengah Sub-District. The results showed that the farmers had not yet implemented hygiene and sanitation in post-harvest processing which involved every activity from the picking of the fruit to its storage. At the fruit picking stage, all colors were collected and then dried together without any sorting. The drying stage did not meet the post-harvest coffee processing standards, as it resulted in high water content of the beans, which was between 62,26 ±0,76% and 13,97±0,55. Likewise, the storage process did not meet the hygiene and sanitation standards because not only were the coffee beans put in sacks, they were also stored in poorly ventilated warehouses or storage areas and mixed with other commodities. This predisposed them to fungi contamination. Two ocratoxin producing fungi, namely, Aspergillus niger and Aspergillus ochraceus were found in processed and stored coffee beans that did not meet hygiene and sanitation standards.

Ceratocystis manginecans causes wilt and death of plants in several important crops and native vegetation in Indonesia. Ceratocystis wilt was recently found to be causing substantial mortality in bullet wood (Mimusops elengi) in South Sumatra. The aim of this study was to describe the symptomatology of the new disease and characterise isolates of C. manginecans obtained from bullet wood plants. Affected plants showed substantial discoloration of the woody xylem and wilt-type symptoms of the foliage, with the eventual death of the whole plant. Isolations from infected trees yielded a fungus that was similar morphologically to C. manginecans, with typical hat-shaped ascospores and light-coloured perithecial bases. Sequencing of the internal transcribed spacer (ITS) and ?-tubulin of isolates confirmed their identification, grouping them with C. manginecans and separating them from all other Ceratocystis species. This is the first report of C. manginecans in Indonesia causing wilt and d...

Ganoderma boninense is the basal stem rot disease (BSR) pathogen that devastates oil palm plantations. Disease infection generally occurs by a single strain of G. boninense, or co-infection of two strains arises as revealed by somatic incompatibility. This study aimed to determine the effects of co-infection of two somatically incompatible G. boninense strains on the BSR disease of oil palm seedlings. Two strains of G. boninense were from 2 oil palm plantations and had different aggressiveness. Co-infection of two G. boninense strains was performed by inoculating the Ganoderma rubber wood blocks to the 3-month-old oil palm seedling and examined for 7 months. The results showed that co-infection with two G. boninense strains had similar disease symptoms, decreased disease severity (score 1.5 compared to 2.0 for a single aggressive strain), and similar seedling growth retardation by the single aggressive strain.

The objectives of the research was to evaluate effect of inoculation Fusarium sp. The pathogen of stem and branch rot disease on tree stage of rubber seedling. The research was conducted at Phytophatology laboratorium Plant Pest and Diseases Departement and green house Agriculture Faculty, Sriwijaya University. The research was arranged in Completely Randomized Design. The treatments were the stage of rubber seedling consisted of two months (A), four months (B) and six months ( C ). Each treatments contained 3 plants and were replicated six times. Result of the study showed that the ages of rubber seedling significantly effected disease severity and number of leaf fall. The rubber seedling two months old showed the disease severity and numbers of leaf fall highes and significantly different compare to the rubber seedling four and six months old. The disease severity and number of leaf fall were 83.41 percent and 77.53 percent.. The lowes were rubber seedling six months old , that wa...

The objective of this research was to study the effects of mixed viral infection and growth stage on chilli (Capsicum annuum L.) production. This study was carried out in a split plot design with plant stage as the main plot and viral infection as the sub-plot. Plant stage as the main plot consisted of four levels, i.e 15 days, after transplanting (DAT), 40 DAT, 65 DAT, and 90 DAT, whereas viral infection as sub-plot consisted of 5 innoculation of viruses, i.e., no viral infection (control), cucumber mosaic virus (CMV) + tobacco mosaic virus (TMV), cucumber mosaic virus (CMV) + potato virus Y (PYV), CMV+PYV and CMV+PYV+TMV. Each treatment was replicated five times. The inoculations were conducted mechanically by rubbing single young leaves which had been dusted with carborandum 400 mesh, with inoculum of respective viruses. Parameters observed in this research were plant height, biomass, and chillies production (number of fruits and the weight of total fruits yield) for each plant. ...

Robusta coffee is a coffee type found in South OKU Regency in Indonesia, and its storage process is highly susceptible to the growth of various fungal species, including fungi that produce Ochratoxin A (OTA). Therefore, this study aims to examine the fungal contamination contained in storage using polystyrene (PS) and gunny sacks for 20 and 30 days. Data were obtained from surveys, interviews, and samples from 30 farmers which stored coffee beans using PS and gunny sacks in May-July 2020. The results showed that the moisture content was higher in storage using gunny sacks than in PS sacks, at 16.94 ± 0.878 % and 15.99 ± 1.33%, respectively. Furthermore, 16 fungal species were present in gunny sack storage, while 14 fungal species were observed in PS sacks. The percentage of OTAproducing fungi A.niger and A.ochraceus in the two stores yielded 100% and 63.3%, respectively.

This research was conducted to study the effect of the application of Pseudomonasspp on infection of Peronosporaparasitica (Pers. Fr), the pathogen of Downy mildew on Chinese cabbage. The research was conducted in the laboratory and greenhouse Department of Plant Pests and Diseases Faculty of Agriculture Sriwijaya University, Inderalaya, OganIlir South Sumatra Indonesia. The research was conducted in the laboratory and greenhouse Department of Plant Pests and Diseases Faculty of Agriculture Sriwijaya University, Inderalaya, Ogan Ilir South Sumatra Indonesia. The research was conducted using Completely Randomized Design with ten treatments including control. ie: isolate A, Isolate B, isolate C, isolate D, isolate E, isolate F, isolate G, isolate H, isolate I and control. Each treatment consists of four replications. Results of the study showed that the application of Pseudomonas spp. can suppress the infection of P. parasitica on Chinese cabbage. The lowest disease intensity was shown by treatment C (isolate Pseudomonas sp.) which was significantly different from control. The best treatment in suppressing disease severity of downy mildew on chinese cabbage was isolate H which had disease severity of 37.07 percent, which was significantly different from control and other treatment.

Bacillus thuringiensis is a gram-positive bacterium that produces crystal proteins toxic (ᴕ-endotoxin) specific to the target insect, but is not toxic to humans and non-target organisms. This study aims to explore the origin of the soil bacterium B. thuringiensis sub-district Sekayu, Banyuasin, South Sumatra and toxicity to larvae of lepidoptera. Fifty soil samples were taken from Musi Banyuasin District, namely 15 from Kayuare strip 2, 20 from Kayuare and 15 from Lumpatan. Isolation, characterization, identification and screening test were conducted in the laboratorium of Pest and Disease, Agricultural Faculty, Sriwijaya University. Isolat codes were given based on the area origin of the samples. Results of the study showed that from 50 isolates of bacteria that had been isolated, there were 15 bacterial isolates, characterized by morphology and physiology the same as B. thuringiensis, which has round colonies, white, wrinkled edges, slippery, elevation arise, aerobic and gram-positive. Of the 15 codes that contain positive isolates of B. thuringiensis, we have obtained several isolates of the following codes: KJ2D5, KJ2N1, KJ2N4, KJ2B3, KJ3R1, KJ3R2, KJ3R3, KJ3R5, KJ3J3, KJ3J4, KJ3P1, DLM5, DLKK12, and DLKK23. Results of screening tests on insects of the Lepidoptera Order showed that there were six isolates that had toxic to Plutella xylostella and Spodoptera litura insects, ie bacterial isolate codes DLM5, KJ3R3, KJ3R5, KJ3J4, KJ3P1, and DLKK23.
