Abstract

The Covid-19 pandemic that has been going on for more than a year has had a major impact on UMKM (micro, small, and medium enterprises). Most of the business actors experienced a decline in sales and some even had to close their businesses. This impact was also felt by pottery craftsmen in the village of Kesilir-Wuluhan, Jember, one of which was the MSME Lies pottery. These MSMEs have difficulty in marketing their products, so sales have decreased drastically, almost reaching 60%. Therefore, the purpose of this assisted village service program activity is to provide assistance in increasing the sales of pottery products with digital marketing strategy. The implementation of the digital marketing strategy begins with the development of pottery products that are tailored to consumer interests during the pandemic, such as various flower pots, souvenirs, kowi and other types of products. In addition, promotions are also carried out through social media such as Facebook and Instagram. Promotion strategy and online sales through Instagram, Shopee and marketplace on Facebook have a significant impact on increasing pottery sales turnover. The average monthly sales turnover either through shopee, marketplace or instagram and whatsapp in the last 6 months from March to August 2021 can reach around IDR 2,500,000-3,500,000.

Abstract

Tumbuhan anggrek dikenal sebagai tumbuhan hias, selain itu juga berpotensi sebagai obat diantaranya adalah Dendrobium linearifolium Teijs & Binn., Bulbophyllum odoratum (Blume) Lindl., dan Vanda tricolor Lindl. Khasiat obat pada tumbuhan adalah karena adanya metabolit sekunder, antara lain alkaloid dan flavonoid. Penelitian ini bertujuan untuk menentukan kandungan alkaloid dan flavonoid pada tiga spesies anggrek berpotensi obat dari kawasan Gunung Gumitir Kabupaten Jember. Sampel ketiga spesies anggrek dipisahkan antara batang, pseudobulb dan daunnya kemudian dikeringanginkan dan dihaluskan sampai mendapat serbuk. Serbuk anggrek di ekstraksi dan diuji secara kuantitatif dengan spektrofotometri. Rata- rata kandungan alkaloid dan flavonoid tertinggi terdapat pada daun. Kandungan alkaloid tiga tertinggi berturut-turut adalah daun Dendrobium linearifolium Teijsm. & Binn. (43,84 mgBE/g), pseudobulb dan daun Bulbophyllum odoratum (Blume) Lindl. (21,91 mgBE/g) dan (18,01 mgBE/g, sedang terendah daun Vanda tricolor Lindl (9,35 mgBE/g). Kandungan flavonoid tertinggi terdapat pada daun Dendrobium linearifolium Teijsm. & Binn. (219,59 mgQE/g) diikuti daun Bulbophyllum odoratum (Blume) Lindl. (132,21 mgQE/g) dan daun Vanda tricolor Lindl. (122,69 mgQE/g) dan terendah batang Dendrobium linearifolium Teijs & Binn (56,26 mgQE/g).

Abstract

Sorghum (Sorghum bicolor L. Moench) is a cereal crop that has the potential to be developed in Indonesia as a food, feed and industrial crop. Sorghum is a C4 plant that has the advantage of efficiency in hot and dry environments. Drought stress is one of the most limiting environmental factors for crop productivity worldwide, and can be caused by water deficits in the soil and in the atmosphere. On the decreasing leaf water status, the rate of CO2 assimilation and the conductance of stomata decreased rapidly. The CO2 concentration mechanism is able to saturate C4 photosynthesis under the relatively low intercellular CO2 concentration. In addition, CO2 photorespiration is likely to be repaired before it exits the bundle sheat cells. The effects of non-stomatal factors include reduced activity of photosynthetic enzymes, inhibition of nitrate assimilation, induction of premature aging, and changes in leaf anatomy. Photosynthesis in C4 plants, including sorghum, involves, others, the PEPC and Rubisco enzymes. Drought can also trigger oxidative stress, which is an environmental condition that has increased Reactive Oxygen Species (ROS) due to an over reduction of the photosynthesis process.

Abstract

Cyclosorus parasiticus (L.) Farw. from Mount Gumitir dominates the understory ferns vegetation along the roadside of a pine-mixed coffee plantation. Previous studies reported the metabolite profile with the flavonoid and alkaloid content. Current observations based on morphological structure of the specimens collection indicated a high variations, therefor molecular identification was required to support the phylogenetic data of the species. The aim of the study was to identify the Cyclosorus parasiticus sample originate from Gumitir using DNA barcode. We used three primers, i.e. ribulose 1,5-biphosphate carboxylase (rbcL), maturase K (matK), and Internal transcribed spacer 2 (ITS2) for molecular identification. The result showed that Cyclosorus parasiticus from Gumitir has a highest similarity with Christella latipinna (NC070300) from China with a value of Percent Identities value of 99.11% based on the ITS2 marker. The rbcL data in this study might contribute to supporting the molecular genus concept from recent Thelypteridaceae phylogeny.

Abstract

Salinity stress enhances plants' growth and development, leading to decreased productivity. Ageratum conyzoides L., also known as Bandotan, is an invasive plant that has spread throughout almost all regions in Indonesia. Investigating the adaptation mechanisms of this plant offered insights into the stress tolerance levels to the salininty and was important for the mitigation of the consequences of its invasivenessnature. The objective of this research was to investigate the impact of salinity stress on the growth and development of A. conyzoides.  The study was carried out in a greenhouse between April and May 2022. The plants were grown under two degrees of salinity stress (i.e., 2000 ppm for moderate stress, and 75000 ppm for extreme stress). The results indicated that A. conyzoides was adaptive to moderate salinity conditions. In extreme stress conditions, A. conyzoides expressed stress by decreasing the plant height and total stomata. The plant adapted by developing flowers at a faster rate as a defense mechanism for the propagation of future generations.

Abstract

Kluwek seeds (Pangium edule Reinw.) have a low germination percentage caused by dormancy due to hard seed coat. Kluwek seed germination takes about 1 month. The purpose of this study was to obtain a combination of treatments that were effective in increasing the percentage of kluwek seed germination and reducing the intensity of kluwek seed dormancy. This study used a Completely Randomized Design (CRD) factorial design. The first factor was immersion time (H) consisting of five levels, namely H0: Control (0 hour), H1: 6 hours, H2: 12 hours, H3: 18 hours, and H4: 24 hours and the second factor was giberellin concentration (G) with five levels namely G0: 0 ppm, G1: 25 ppm, G2: 50 ppm, G3: 75 ppm and G4: 100 ppm. Data analysis used Analysis of Variance (Anava) and further tested with Duncans' Multiple Range test (DMRT) at a significant level of 5%. The results obtained showed that the percentage of seed germination without immersion is 6.67%. Soaking using aquades produces an average germination percentage of 28.33%. The most effective treatment was GA3 75 ppm for 24 hours with seed germination of 60%, while the value of dormant intensity is 40%.Keywords: dormancy, germination, gibberellin, kluwek.

Abstract

Dumortiera hirsuta is one of the liverworts that can be used as a medicinal to prevent infection by pathogenic bacteria. The content of secondary metabolites of D. hirsuta has potential as antibacterial properties includes flavonoids, alkaloids and steroids. This research is to analyze the antibacterial activity of moss D. hirsuta against pathogenic bacteria that will be beneficial to humans. Liverworts of D. hirsuta were extracted using ethyl acetate solvent and tested against three types of pathogenic bacteria using the agar well-diffusion method. The results of this study indicated that the ethyl acetate extract of D. hirsuta at 100% concentration could inhibit the growth of Escherichia coli, Staphylococcus aureus, and Salmonella typhi bacteria. The range of antibacterial activity categories of the ethyl acetate extract of D. hirsuta to E. coli, S. aureus, and S. typhi between weak to moderate.
