Abstract

Crocidolomia pavonana is an important pest in Brassicaceae. Botanical insecticides is pest control alternative which meet to eco-friendly manajement. This study aims to determine lethal concentration of single and mixture of water extract of Piper aduncum (Piperaceae) fruit and Cymbopogon cirtatus (Poaceae) stem against Crocidolomia pavonana larvae. The study was conducted in laboratory experiment through preliminary test and advance test using a completely randomized design (CRD). Observations were included to larval mortality, antifeedant effect, and duration of larval development. Bioassay was done against second instar larvae of C. pavonana using leaves immersion method during 48 hours. The results show that LC50 and LC95 value of mixture extract are 2.83% and 5.79% respectively. Based on index combination analysis, P. aduncum and C. citratus mixture extract were antagonistic at LC50 and additive at LC95 . Water extract of P. aduncum and C. citratus were relatively weak to influence feeding activity of C. pavonana larvae (41%). Mixture extract also extend larval development from second instar to third instar around 0.24 days and third instar to fourth instar around 0.97 days.

Abstract

Sorghum farmers in West Sumatra, especially Padang Pariaman, have low knowledge of sorghum varieties in plants. This is because sorghum relatively new food commodity cultivated in this area. The three varieties of sorghum that are often grown by farmers are numbu, Super 1, and red varieties, which differ in morphology, texture, and taste. The general procedure for harvesting sorghum begins with cutting panicles, drying them in the sun, threshing them, and drying them again until the moisture content reaches 12%. Then the sorghum seeds are crushed using a sosoh machine so that the tannin in the outer skin layer is lost. After going through the filling process, sorghum rice is produced, can be consumed directly by cooking it into porridge, cooked like rice, or mixed with rice (rasgum). Sorghum rice can also be ground into flour and used as a base for making various types of food. The community service team has carried out a chemical analysis of sorghum flour. There are amylose and amylopectin analysis, starch content analysis, starch gelatinization profile, and reducing sugar. The objective of this activity is to transfer knowledge and technology related to sorghum rice and sorghum flour as raw materials for food processing. From the data obtained, known that red sorghum has the best performance as raw material for wet-processed food, while Numbu and Super 1 are suitable as raw materials for dry processed food.

Abstract

There is still a lack of knowledge of Andalas University inventors on the importance of the Innovation Readiness Level (KATSINOV), which is a tool to measure the level of innovation. Therefore, it is necessary to hold socialization to the inventors and SMEs of Padang City to provide information about the importance of this KATSINOV. This socialization activity was carried out through a zoom meeting by inviting experts in this field. The method used is the presentation method, namely by providing socialization about KATSINOV to the inventors and tenants of Andalas University. In addition, the methods used were observation and direct interviews with Andalas University inventors to identify and measure KATSINOV's respective products. Socialization was provided by resource persons who understand KATSINOV. Katsinov is organized into six levels and seven key aspects covering technology, market, organization, partnership, risk, manufacturing and investment. This socialization activity resulted in the measurement of the level of product innovation readiness of Andalas University research. Furthermore, it was necessary to design a website-based application to facilitate the measurement of KATSINOV research products and West Sumatra MSME products.

Abstract

The botanical insecticide nanoemulsion is a pesticide having an oil phase and aqueous phase that spontaneously emulsify and range in size from 20 to 200 nm. Bio-combi extracts frequently contain intricate combinations of active ingredients that may work in concert to increase bioactivity. The goal of the study was to develop the optimal nanoformulation and investigate the physiological effects of a synergistic nanoemulsion made from Tephrosia vogelii leaves and Piper aduncum fruit extracts as a substitute pesticide for Spodoptera frugiperda larvae. Low-energy spontaneous emulsification with a magnetic stirrer was used to create nanoemulsions, which were then subjected to a toxicity and food absorption test. Malvern's Zetasizer Nano (ZN), which was used to analyze the insecticidal nano formulae for PSA, revealed that the particle sizes for the 1:1, 3:1, and 1:5 ratios were 204 nm, 4724 nm, and 97 nm, respectively. Only the 1:5 formula, which is classified as a nanoparticle, met the standards for a nanoemulsion and produced S. frugiperda mortality of 82.34% at a concentration of 0.56%, and the LC25, LC50, and LC95 values were 0.1, 0.22, and 1.59%, respectively. The analyzable results demonstrated that the mixed nanoemulsion was additive at the LC50 value was 0.95 while the LC95 value was 0.70%, meaning only marginally synergistic

Abstract

The bacterial species Xanthomonas axonopodis pv allii (Xaa) is an important pathogen causing leaf blight in shallots. The use of botanical pesticides with nanoemulsion formulations has become a common alternative. This study aims to determine the characteristics and optimum concentration of the mixture of essential oil of Piper aduncum and fragrant Cymbopogon nardus waste. Nanoemulsion formulations are made using spontaneous emulsification methods. Besides, testing Bacillus thuringiensis strain MRSNR3.1 and its secondary metabolites toxicity against Xaa was carried out by the diffusion method using paper discs to determine the diameter of the inhibition zone. The results demonstrate that all four concentrations, 1%, 2.5%, 5%, and 7.5%, could control Xaa bacteria. A concentration of 1% is considered more optimal than the other three   concentrations in bactericidal effects against Xaa, as manifested in the formed clear zone (diameter of 3.17 cm). Besides, Bacillus thuringiensis strain MRSNR3.1 and its secondary metabolites were also effective againstXaa after four days of incubation with inhibition zones of 3.04 ± 0.44and 2.21 ± 0.28, respectively. Hence, it is concluded that nanoemulsion at 1% concentration and Bacillus thuringiensis strain MRSNR3.1 have  bactericidal properties that can be used to control Xaa

Abstract

Applying science and technology encourages innovation, increasing development productivity, independence and national competitiveness. Indonesia has a science and technology area named Science Techno Park (STP). Maturity measurement is an indicator of the level of an STP to apply science and technology for the welfare of society. There are three levels of maturity for STP, which are low (pratama), middle (madya), and high (utama). Before entering the best maturity level, STP must go through various kinds of preparation and fulfil the elements contained in it. The community service activity team at Universitas Andalas conducted a web seminar (webinar) to socialise the maturity assessment for STP Unand from the academic side. The webinar invited two experts on STP maturity measurement. One of the primary assessments is the number of products produced that are expected to come from the results of academic research. This activity can help STP Unand prepare to increase its maturity to a high level.
