Abstract

Irrigated rice fields with flooded cultivation systems tend to produce more carbon than they sequester, as the vegetation is dominated solely by rice plants. In contrast, plantation agroecosystems, which contain a more diverse range of plant species, have greater potential for carbon sequestration due to their higher biomass. This study aimed to analyze the relationship between plant biodiversity and vegetation carbon sequestration in irrigated rice fields and plantation areas within the Upper Tuntang Sub-watershed, at Semarang Regency, Central Java. The research involved 48 sample plots, consisting of 8 irrigated rice field sites and 40 plantation sites, selected based on carbon potential using NDVI data. Research stages included establishing sampling plots, plant species identification, and measuring both biodiversity and vegetation carbon sequestration. Results showed that the biodiversity index in irrigated rice fields fell into the low category, as rice was the only dominant species. In contrast, the plantation exhibited medium biodiversity indices due to the presence of more varied plant species. Carbon sequestration was highest (7,68) at point 5 and lowest (0,01) at point 7 in irrigated rice fields, while in plantation it was highest (230,00) at point 37 and lowest (0,01) at point 39. To assess the relationship between biodiversity and carbon sequestration, the plots were classified into three vegetation structure types: (1) understory plants, (2) understory plants and trees, and (3) understory plants, trees, and shrubs. A significant relationship between biodiversity and carbon sequestration was observed in plots containing both understory plants and trees with sig. value (2-tailed) of 0,047. However, no significant relationship was found in plots dominated solely by understory vegetation with sig. value (2-tailed) of 0,897, nor in plots containing understory, trees, and shrubs with sig. value (2-tailed) of 0,255. The research can serve as a basis for sustainable agroecosystem management, as it shows that increasing plant biodiversity can contribute significantly to increased vegetation carbon sequestration in the Upper Tuntang Sub-Watershed. Keywords: biodiversity, carbon sequenstration, plantation, rice field

Abstract

Crispy chicken and crispy mushrooms are examples of processed products using crispy seasoned flour. There are many spice flour producers, from small, medium, and large to micro industries. UD. LIBAS is one of the producers of crispy seasoning flour on a home industry scale (MSMEs). This research aims to improve the quality of “IIBAS” crispy seasoned flour through product rebranding. The research stages that be carried out are the process of data collection, analysis, and interpretation to achieve the research objectives. The existing brand of crispy seasoning flour "IIBAS" includes main elements such as visual identity, product excellence and the values it promotes. Visual identity includes a logo, attractive packaging, tagline, and color choices that reflect the value and quality of the product. The brand positioning of "IIBAS" crispy seasoned flour includes superior taste and a more affordable price compared to competitors. Important attributes of "IIBAS" crispy seasoned flour include ease of reading information on packaging and product distribution, which is a top priority for improvement. The level of consumer satisfaction towards "IIBAS" crispy seasoned flour reached 79.42% (satisfied category). Thus, it is hoped that this branding will increase the value of UD. LIBAS's crispy seasoned flour products and increase market share and sales turnover, thereby increasing the profits of the MSME producers. Keywords: branding, crispy, logo, MSMEs

Abstract

Temu mangga (Curcuma mangga Val.) can enhance immune function due to its active compounds. The purpose of this study was to determine the antioxidants level and total phenol content of blanch-treated Curcuma mangga powder, then evaluate immunological enhancement through orally Curcuma mangga Val. intake on Wistar male rats (in-vivo). Temu mangga rhizomes were peeled, washed, and subjected to steam blanching for varying times (0, 2.5, 5, 7.5, and 10 minutes). Blanch-treated temu mangga was dried using a cabinet dryer, ground, and sieved to obtain powder. Analysis of the temu mangga powder included antioxidant activity (DPPH) and total phenol content. In-vivo testing on experimental rats included SOD, IgE, IgG, and IgM levels. The selected temu mangga rhizome, steam-blanched for 5 minutes, exhibited excellent antioxidant properties (81.46% RSA DPPH value and 6.08 mg GAE/g total phenol content). According to the in vivo results, the group of rats receiving temu mangga showed a notable increase in SOD levels (72.92%) compared with the NaCMC-treated group, and were not substantially different from commercially available supplements (stimuno). Experimental rat antibody values were IgE at 74.02 ng/mL, IgG at 18.20 ng/mL, and IgM at 2.97 ng/mL, significantly better in rats given temu mangga powder than those given Na-CMC and stimuno. In the future, this study can provide more insight into the potential of Curcuma mangga Val. processed by steam blanching and its potential as an immunomodulator. Keywords: antioxidant activity, blanching, immunomodulator, in-vivo, temu mangga
