Abstract

[TUNGRO DISEASE ON RICE PLANT (Oryza sativa) IN TABA PENANJUNG DISTRICT: DISEASE INCIDENCE AND MOLECULAR DETECTION OF VIRUSES]. Tungro is one of the important diseases of rice plants. Tungro disease caused by Rice tungro bacilliform virus (RTBV) and Rice tungro spherical virus (RTSV). This research aims to obtain information on the spread of the disease, vector population, and molecular detection by polymerase chain reaction method. This research was conducted from December 2019 to April 2020 in rice fields in Taba Penanjung sub-district, Bengkulu Tengah district at ± 540 meters above sea level and virus detection in the Laboratory of Biotechnology and Genetics Department of Biology Faculty of Mathematics and Natural Sciences (MIPA) and Laboratory of Plant Protection, Agriculture Faculty, Bengkulu University. Data analysis used descriptive analysis. The results showed that the highest disease incidence on the seven weeks after planting (wap) is 1.7% and the highest population of the vector on the 7 wap with an average of 7.7 vector/100m2 in the village of Taba Penanjung. Detection of viruses with the PCR method with the specific primer DAF/DAR succeeded in amplification of DNA band measuring 1,400 bp. RTSV was not detected by RT- PCR using a specific primer or RTSV. The result of this detection shows that the symptoms of tungro on rice plants in the cultivation of Taba Penanjung district associated with RTBV infection. RTSV unable to detect can be caused by many factors in the detection process, including total RNA extraction, cDNA synthesis, DNA amplification, and DNA visualization of PCR products.

Abstract

This research was conducted to 1) Analyze the perception of consumers on the attributes of chili, and 2) Know which chili products are selected by consumers based on shape,  size and which are most wanted to buy. Forty consumer respondents were taken by accidental sampling technique.  Consumers are asked to assess 10 types of the UNIB chili varieties, both monoculture and combination polyculture between varieties. The results showed that the majority of respondents stated that the size and shape attributes were important as the basis for the decision to buy chili, while the attributes of uniform size and shape are considered normal.  The variety of chili which consumers like because of their size, shape and desire to be purchased were UNIB C H13. While for this type of combination, the combination of UNIB C H13 and UNIB C H53 is desired to be purchased by consumers. This type of combination should be cultivated by farmers because it is resistant to pests, high productivity and preferred by consumers.

Abstract

Gourami fish has been cultivated and marketed by the Amanah Sejati cooperative located in Bengkulu city. Gurami is sold as fresh product. The price is not comparable with the cost of gurami cultivation. Therefore, it is necessary to make an effort to increase the economic value of the gourami fish. One of the solutions is to make it into presto gourami products. The gourami fish is then vacuum-packed to improve the quality and extend its shelf life. Community service aims to (1) provide knowledge about the type of packages, and (2) provide knowledge about how to vacuum packaging on presto gourami. These community services are coordination and socialization, counseling, and practice. These services were going well. The participants were enthusiastic about the counseling and practice.

Abstract

Pepper yellow leaf curl Aceh virus (PepYLCAV) and pepper yellow leaf curl Indonesia virus (PepYLCIV) are begomoviruses that dominate chili cultivation in Indonesia. Characterization of these two begomoviruses is essential as basic information for the development of virus control technologies. The symptoms on chili plants indicate that PepYLCIV is more severe than PepYLCAV, with severe mosaic, curling, and yellowing, whereas PepYLCAV causes only mild mosaic and yellowing. Sequencing results also show that the nucleotides and amino acids between PepYLCAV and PepYLCIV are significantly different. This suggests that the pathogenicity of the two viruses on chili plants differs. Protein structure predictions using AlphaFold3 also show significant differences. Based on available data, control of PepYLCAV and PepYLCIV can be achieved using different approaches, as these viruses have distinct sequences that may affect their pathogenicity.

Abstract

Melon cultivation has increased rapidly in recent years and is frequently associated with widespread virus-like symptoms in Bengkulu Province, Indonesia; however, thereis no formal documentation of the mixed viral infections has been available. Therefore, this study aimed to detect major viruses infecting melon crops in Bengkulu Province and to evaluate their occurrence based on field symptoms and serological detection. Field surveys were conducted at three melon cultivation sites: Kandang Limun Village (Bengkulu City), Air Sebakul Village (Central Bengkulu Regency), and Tawang Rejo Village (Seluma Regency). Symptomatic leaf samples were collected purposively. Virus detection was performed using the Dot Immunobinding Assay (DIBA) with antisera specific to Cucumber mosaic virus (CMV), Tobacco mosaic virus (TMV), and Papaya ringspot virus (PRSV). The results showed that the dominant symptoms of viral infection in melon plants included mosaic, vein banding, chlorosis, leaf curling, and stunted growth in both Snow & Rock and Merlin F1 varieties. Disease incidence varied among varieties and locations, with the highest incidence recorded in Snow & Rock (73.3%). Serological detection revealed that 100% of symptomatic samples tested positive for CMV, TMV, and PRSV, confirming that all infections occurred as mixed infections. This study represents the first report of mixed viral infections in melon crops in Bengkulu Province. These findings demonstrate that overlapping and variable field symptoms cannot be attributed to a single virus and cannot be reliably distinguished through visual diagnosis alone, highlighting the importance of laboratory-based diagnostic approaches for accurate virus identification.
