    Abstract: Anthracnose caused by Colletotrichum gloeosporioides is one of important diseases causing postharvest losses on chili. This study aimed to determine the effectiveness of the zero energy cool chamber (ZECC) in reducing the severity of anthracnose in Capsicum frutescens L. and extending the shelf life of chilies. The research was started by designing and building ZECC as a storage area for chilies. Chilies with and without fungal inoculation were stored in ZECC and storage chamber at room temperature. C. gloeosporioides experienced a growth inhibition of 40.48% after being stored in ZECC compared to its growth at room temperature. Storage of chilies in ZECC was able to reduce the severity of anthracnose by 56.2% on the 15th day, did not affect vitamin C content and total dissolved solids (TSS) and was able to reduce chilies weight loss during storage. Based on the organovisual test using the visual quality rating method and the Hedonic sensory test, consumers prefer chilies stored in the ZECC. The results showed that storage in ZECC could extend the shelf life of chilies. This storage model does not use electricity or is zero energy so it can be used by small scale farmers. This is the first report on the use of ZECC for the management of anthracnose in postharvest chilies in Indonesia.

    Abstract: The demand for shallots has increased along with the Indonesian population. To achieve shallot production goals, farmers began to plant shallots outside usual planting season. However, unfavourable environmental conditions and pest attacks are obstacles faced by farmers. The use of Biological Control Agents (BCA) is a way to improve plant growth and protect plants against plant pathogens or even abiotic stresses. The purpose of this study was to evaluate the response of shallot plants after BCA (Bacillus and Mycorrhizal Fungi) application, especially against twisted disease during off-planting season. This research was conducted by preparing BCA isolates, applying BCA, measuring disease incidence and intensity, observing plant growth development, analyzing phenol content, and analyzing phosphate content. Results showed BCA Bacillus and mycorrhizal fungi did not inhibit Fusarium spp. infection. Agronomic measurements showed no significant difference in crown weight and root weight, but isolate B8 significantly increase the number of leaves while isolate M significantly decreased plant height. Isolates B6, B7, and M significantly reduced the total phenol content in shallot plants. Phosphate analysis on isolate M did not have significant effects on shallot plants, while BCA Bacillus and Mycorrhizal fungi application could not suppress twisted disease. Nevertheless, B8 treatment has the potential to increase shallot growth; therefore, further research must be conducted.

    Abstract: Abstract. Ivayani, Widiastuti A, Suryanti, Suharjo R, Priyatmojo A. 2022. Short Communication: First report of Xanthomonas sacchari causing rice sheath rot disease in Lampung, Indonesia. Biodiversitas 23: 6463-6470. Rice sheath rot is recently reported as an emerging important rice disease in Indonesia, which can cause yield losses of up to 85%. Due to its potential loss, serious attention should be given on the disease. However, there is still limited information on the causal agent of the disease in Indonesia, especially from plant pathogenic bacteria. One bacterial isolate (LSE 33) was obtained from the sheath rot symptom of rice. Pathogenicity test revealed that bacteria produced symptoms that were similar to those obtained from the field. Based on the sequence analysis of 16S rRNA gene region, isolate LSE 33 was placed within group of the type strain and reference strains of Xanthomonas sacchari. Strain LSE 33 had 99.93% sequence similarity with Xanthomonas sacchari strain SAM 144 and strain AF 10 isolated from rice, and 99.35% similarity with strain LMG 471T isolated from sugarcane. To our knowledge, this is the first report of X. sacchari causing sheath rot on rice in Indonesia.

    Abstract: Abstract. Widiastuti A, Suryanti, Giovanni AC, Santika IA, Paramita NR. 2023. Fungal community associated with mixed infection of anthracnose and stem end rot diseases in Chokanan Mango. Biodiversitas 24: 2163-2170. Anthracnose and stem end rot are the top two prevalent diseases causing losses in mango fruit worldwide. Both diseases often appear together in ripened fruits. The aim of this research was to evaluate the fungal community associated with mixed infection of anthracnose and stem end rot diseases in Chokanan mango based on metagenomics analysis through amplicon targeted next generation sequencing. The results showed that approximately 152,000 sequences were observed. The average total tags from the observed OTUs number were 146,485, of which 126,230 were taxon tags. The ten most common occurring fungal genera were Colletotrichum, Penicillium, Diaporhte, Purpureocillium, Aspergillus, Cunninghamella, Neofusicoccum, Mortierella, Rhizopus, and Kazachstania. Of these, genus Colletotrichum showed 77% dominance of based on Krona display value. Based on the number of OTUs, seven species, such as Colletotrichum gloeosporioides (Penz.) Penz. & Sacc., Penicillium simplicissimum (Oudem.) Thom, Neofusicoccum cordaticola Pavlic, Slippers & M.J.Wingf., Diaporthe arengae R.R.Gomes, Glienke & Crous, Purpureocillium lilacinum (Thom) Luangsa-ard, Houbraken, Hywel-Jones & Samson, Alternaria alternata (Fr.) Keissl., and Fusarium oxysporum Schltdl., showed dominance in mixed infection. These findings reveal the major status of post-harvest pathogens in mango fruits that should be controlled. This is the first report on N. cordaticola and D. arengae associated with mixed infection of anthracnose and stem and rot disease on post-harvest mango in Indonesia.

    Abstract: Apriadi T, Pratama G, Putra RD, Jumsurizal, Jaya YV, Firdaus M, Arpas HD, Suryanti A. 2018. Comparative study on the fish diversity from natural and bauxite post-mining in wetland system of Bintan Island, Indonesia. Biodiversitas 19: 967-973. In this study, the fish populations between two different wetland systems in Bintan Island, Indonesia, i.e., bauxite post-mining (Kijang) and natural wetland (Toapaya) were compared and to propose a newly index namely Environomic of Fishes Index (EFI) to their respective ecosystems. The purposive random sampling at six stations, each of three stations representing bauxite mining (Kijang) and three stations representing a natural wetland (Toapaya) were used in this research. The numbers of fish species and the abundance were enumerated. The new index derived from the value of diversity index (Shannon), similarity index (Evenness), dominance index (Simpson's), conservation status, and economic value were also evaluated. The natural wetland has higher fish diversity than bauxite post-mining. The total species found were twenty-four. The same seven species were found in both areas. Twelve species were obtained from bauxite post-mining, and nineteen species were obtained from natural wetland. Puntius tetrazona and Rasbora heteromorpha were the common species in area study. The diversity and dominance index was at low category, Evenness index was at high category in all stations, except in tidal swamp station at bauxite post-mining. The EFI in natural wetland was higher than bauxite post-mining. The three community index value, economic value, and conservation status of natural wetland were higher than bauxite post-mining.
