Abstract

Ficin is an enzyme derived from Ficus sp., recognized for its applications in the food and pharmaceutical sectors. Utilizing solar energy for enzyme drying has been shown to be economical and environmentally sustainable while preserving enzyme activity. This study aimed to determine the amino acid composition of crude ficin from Ficus padana Burm. f., and was extracted and dried with solar energy. The analysis of amino acid components was conducted using the UPLC technique. The results indicated the presence of numerous important amino acids, with L-aspartic acid being the highest concentrated at 1.85 mg/g and L-leucine at 1.41 mg/g. Significant quantities of L-glutamic acid (1.33 mg/g), L-serine (1.14 mg/g), and L-lysine (1.05 mg/g) were also identified. The solar drying process showed no significant loss of amino acids. The findings suggest that solar drying does not negatively impact the amino acid composition in fiction, therefore enhancing its practical significance, particularly for the food and pharmaceutical sectors.

Abstract

This study aims to quantify the protein content in crude ficin enzymes obtained from the fruit and latex of various Ficus species and Papaya. This research has been encouraged by the considerable potential of these enzymes in different biotechnological applications, while data with regard to the protein content of these enzymes is limited. This study used a quantitative approach using qubit fluorometer to quantify the protein content in crude enzymes derived from the fruit and latex of these plants. Based on results, the protein content in crude ficin enzymes, two types of research obtained from Ficus aurata (Miq.) fruit was 0.92µg/ml and from papaya fruit as 3.16 µg/ml. For latex, it was observed that the protein content in crude ficin enzymes was determined as 6.14 µg/ml for Ficus aurata (Miq.), 2.58 µg/ml for Ficus racemosa L., and 5,27 µg/ml for Ficus padana Burm.f.. The protein content from papaya latex was 15,98 µg/ml. These findings show the differences in the protein content of the enzymes obtained from different species of Ficus and Papaya as a basis for further study on using these enzymes for biotechnological purposes.

Abstract

The Sungkai Permai Lambung Bukik Farmer Group, Padang City, generally cultivates in monoculture, with limited productive land. The land is planted with rice, secondary crops such as corn, and some peanuts. In the past two years, corn farmers often experience crop failures, especially during the rainy season, where the sun shines less due to global climate change. Therefore, diversifying commodities on limited land so that land efficiency increases are significant to prepare the next source of seeds. To support increased land use efficiency, optimal soil conditions are needed. Utilization of Arbuscular Mycorrhizal fungi can improve soil fertility and is expected to become an alternative technology in plant cultivation. Science and technology activities based on the Study Program and the Assisted Nagari (IbPSNB) were carried out in groups of Permai Sungkai Farmers in the form of 1) Counseling on the pattern of corn-peanut intercropping cultivation, and how to make CMA spore cultures, 2). The demonstration plot for corn-peanut intercropping cultivation. Through this activity, farmers finally understood the benefits and patterns of corn-peanut intercropping. Farmers understand the role and method of making CMA spore cultures. Several farmers cultivated corn-peanut intercropping. Two farmers at the demonstration plot managed to harvest corn and peanuts at the same time. Other farmers have failed to harvest corn due to pest attacks but have succeeded in harvesting peanuts so that the losses experienced by farmers are reduced, and they still have stock of seeds for the next planting season.

Abstract

Patchouli (Pogostemon cablin Benth.) is among the top 20 essential oil-producing plants traded in the global market. This plant shows narrow genetic diversity due to non-flowering and seed production, increasing the challenges in obtaining new varieties through crossbreeding. Therefore, this research aimed to apply mutation method using ultraviolet-C irradiation combined with tissue culture to broaden the genetic diversity of patchouli. The potential of UV-C irradiation and the morphological changes occurring in the plant were explored from October to December 2023 at the Tissue Culture Laboratory, Andalas University, Padang. In addition, the experiment was arranged in a Randomized Complete Block Design (RCBD) with 10 treatment levels and 3 groups. The treatments included UV-C irradiation doses of 0 (wild type), 30, 60, 90, 120, 150, 180, 210, 240, and 270 minutes at a distance of 30 cm. Data for each patchouli plant per observation variable were presented as mean values, variance, and standard deviation and analyzed using an unpaired t-test. The results showed that exposure to ultraviolet-C radiation impacted several morphological characteristics, such as chlorosis, delayed bud development, increased bud and leaf count, as well as faster bud growth. This phenomenon shows the potential of ultraviolet-C radiation as a physical mutagenic agent.

Abstract

Titan arum (Amorphophallus titanum Becc.) is an endemic species of Indonesia that is found naturally only in Sumatra and is classified as endangered, with an estimated 303 mature individuals remaining in their natural habitat. The population is decreasing due to deforestation, tuber exploitation, long flowering times, and protandry. Therefore, both in-situ and ex-situ conservation programs are necessary to preserve this species. The research aims to explore natural populations, analyze habitat conditions, develop propagation methods, and conduct reintroduction efforts to support the conservation of A. titanum. This study was conducted from 2023 to 2024 in Palupuah, Agam Regency, the Agriculture Faculty of Universitas Andalas, and several locations for the reintroduction of A. titanum. The research found that A. titanum habitat consists of forests rich in humus and litter, as well as banana cultivation areas. During the exploration, 7 individuals were identified: one in dormancy, one fruiting, and 5 in the vegetative phase. Seed germination experiments categorized seeds into seven classes based on their weight. The most dominant seed class weighed between 2.9 g and 3.2 g, comprising 38 seeds or 26.9% of the total. The germination rate and seedling growth were high, as all seeds exhibited 100% and produced seedlings of relatively uniform size. Propagation was carried out using in vitro culture techniques with petiole explants. The results showed that 2 mg L-1 benzyl aminopurine (BAP) successfully induced callus formation with a 100% induction rate, while a concentration of 1.5 mg L-1 achieved the highest shoot induction rate at 58.3%, with an average of 1.3 shoots and 7.9 roots per explant. The propagated seedlings were subsequently replanted in several locations for reintroduction activities.

Abstract

Plant breeding programs need to be carried out in order to improve the genetics of wheat that is able to adapt to tropical environments through hybridization, mutation induction, tissue culture, and genetic transformation.  In vitro culture through somatic embryogenesis pathways plays an important role in genetic improvement and its integration with other breeding programs can positively affect the improvement of wheat quality, quantity, and development in Indonesia. The purpose of this study was to obtain an embryogenic callus induction method from the Dewata variety using five different types of explants, namely mature Seeds, immature embryos, immature seeds, leaf,  stem, and to obtain combination of plant growth regulators and putrescine on somatic embryogenesis of wheat.   The experimental design was prepared based on a complete randomized design with a combination treatment of embryogenic callus induction media consisting of 9 levels, namely: 1 ppm 2.4- D, 1 ppm 2.4-D + 1 ppm Picloram, ppm 2.4-D + 1 mg / L Picloram, 1 ppm 2.4-D + 10-4  M Putrescine, 1 ppm 2.4-D + 1 ppm Picloram +10-4  M Putrescine, 2 ppm 2.4-D + 1 ppm Picloram + 10-4  M Putrescine, 1 ppm 2.4 D + 10-3 M Putrescine, 1 ppm 2.4 D + 1 ppm Picloram + 10-3 M Putrescine, 2 ppm 2.4 D + 1 ppm Picloram + 10-3 M Putrescine. The results showed that the media used was able to induce embryogenic callus using mature seed and immature embryo, but  immature seed and leaf were not able to produce embryogenic callus. The best media  that produced the highest percentage of embryogenic callus was 2 ppm 2.4-D + 1 ppm Picloram + 10-4  M Putrescine with as much as 85.9% in young embryo explants.
