Abstract

The recent upsurge in sporting events has instigated a positive shift in the habits of Generation Z, placing a strong emphasis on embracing a healthy lifestyle through sports while also prioritizing other aspects of life. This comprehensive study delves into the impact of sustainable marketing activities (SMA) on the perceived value and self-image associated with sporting events, as well as its influence on the intention of Gen Z individuals to actively participate in these events (Sports User Behavioral Intention/SUBI). Given the paramount importance of sustainability in organizing sporting events, this study aims to uncover effective strategies for marketing these events to appeal to a wider user base, both in digital and non-digital realms. Through comprehensive data collection via questionnaires and rigorous analysis using the PLS (Partial Least Squares) method, we anticipate elucidating the intricate relationship between SMA, sports event image, perceived value, and sports user intention. Additionally, we seek to explore the mediating role of perceived value and event description in this dynamic relationship. The results of this study hold the potential to revolutionize sustainable marketing for sports events and carry profound implications for event management and sustainability. By identifying limitations and opportunities for future research, this study paves the way for further advancements in this vital field.

Abstract

This research aimed to determine the effect of adding three different starters, such as Lactobacillus plantarum, Azospirillum sp., and Trichoderma sp., on gracilaria seaweed for bok choy growth. The starter optimized fermentation and improved fertilizer quality in growing bok choy. The seaweed was reduced in size, soaked in 1% phosphoric acid solution, then homogenized and heated with 3% molasses to provide microbial nutrition and 1% KOH to maximize mineral content. Fermentation was carried out for 14 days in the microbial exponential phase for decomposition. The results showed that the addition of L. plantarum and Trichoderma sp. to gracilaria seaweed liquid fertilizer produces the highest values of gibberellin (147 ppm), auxin (140 ppm), and cytokinin (96 ppm). Next, the fertilizer was applied to bok choy to determine the effect on its growth. The highest fresh yield of bok choy was 64.0±1.41 g, the highest chlorophyll A content was 6.70±0.01%, and chlorophyll B was 2.30±0.03%. Even though the control treatment had the highest C/N ratio compared to the other treatments, the highest yields of bok choy freshness, height, and leaf area were found when applying liquid fertilizer with L. plantarum and Trichoderma sp. starter. The study concluded that bok choy growth was significantly encouraged by fertilizer-seaweed with high levels of phytohormones compared to mineral content. Adding L. plantarum and Trichoderma sp. is a good starter for increasing the growth-promoting properties of liquid seaweed fertilizer.

Abstract

Calcium is a macromineral essential by human body, with deficiencies often leading to bone-related issues. Red snapper bone waste is a source of calcium. The bioavailability of calcium is maximized when present in microscopic particles, such as bio-calcium. This study aims to identify the optimal milling time to produce bio-calcium from red snapper bones, evaluating parameters such as water content, particle size, and yield. Biocalcium was extracted from red snapper bone meal using a 1 N NaOH solution (1:3 ratio) with milling times of 1, 2, and 3 h. Analysis of the red snapper bone meal including yield, particle size, chemical composition, calcium, and phosphorus content. The bio-calcium was characterized based on water content, particle size, yield, Fourier-transform infrared spectroscopy (FTIR), and morphological structure using a scanning electron microscope (SEM). The results demonstrated that a 3-hour milling time yielded bio-calcium with a particle size of 410.8 nm, a water content of 4.51 ± 0.15%, and a yield of 4.12 ± 0.03%. SEM revealed a uniform morphology. FTIR spectra indicated the presence of carbonate, amine, hydrocarbon, and hydroxyl groups, suggesting residual organic substances such as protein, fat, and water. The uniform spectra across all samples highlight the consistency of the extraction process, ensuring a similar chemical composition.

Abstract

Entrepreneurship is a crucial aspect in Indonesia in 2024. In the post-COVID-19 era, livelihoods can no longer rely solely on employers but must also be developed from the grassroots level through collaboration to create new job opportunities. This is essential to attract the interest of Indonesia's productive generation, particularly among rural communities and, more broadly, among nearby urban areas. Pasigitan Village, located in Boja Subdistrict, Kendal Regency, is a highland area with excellent agricultural potential. In addition to its agricultural products, Pasigitan Village also has side industries in the form of home-based businesses producing palm sugar, either in solid or bulk form, which holds great potential to be marketed to sugar export suppliers. Based on this, the UNNES service team aims to assist these home-based industries in obtaining the PIRT (Household Food Industry) certification. This certification includes training to help producers comply with good manufacturing practices and meet market standards, allowing their palm sugar products to be marketed more broadly and reach more distant markets. The selected method for this community service activity is socialization and assistance. The socialization will explore the palm sugar producers in Pasigitan Village who are part of the home-based industry group and familiarize them with PIRT standards. The assistance will then provide knowledge, understanding, and skills on how to achieve the PIRT standards. The goal is to address the existing problems and create a positive impact.
