The majority of the local population in this region engage in citrus farming as their primary means of income. The lack of knowledge among citrus growers in Belantih Village about the processing of citrus fruits into long-lasting processed products is evident. The primary objective of the community service activities is to enhance knowledge and expertise in the processing of citrus fruits into value-added products, hence extending their shelf life and augmenting their economic worth. The implementation of counseling and mentorship programs, technological transfer initiatives, and training sessions focused on the processing of oranges into jam. The individuals included in this study were members of the women farmer group known as "Widya Pertiwi". The service activity consists of several steps, including the provision of materials and demonstrations on citrus processing, followed by a final evaluation in the form of a post-test administered through the distribution of questionnaires. The outcomes of counseling and training revealed that participants, utilizing the experiential learning approach and training, expressed their ability to comprehend and effectively execute the processing of citrus fruits into various culinary derivatives. This skill acquisition was particularly beneficial during periods of abundant fruit harvest, as it allowed for the generation of increased value and income. The findings of the study indicated a significant improvement in general knowledge. Specifically, 93.33% of participants reported a clear understanding, while the remaining 6.67% expressed comprehension regarding the processing of citrus fruits into value-added products following the completion of the service activities. Notably, no respondents reported a lack of understanding or confusion. The findings indicate that all participants belonging to the Women Farmers group have a keen interest in enhancing their competencies and implementing citrus fruit processing techniques to produce jam products. This approach aims to mitigate fruit rotting during periods of ample fruit availability.</p> </td> </tr> </tbody> </table> Astiari Ni Komang Alit, Anom Sulistiawati Ni Putu, I Nengah Suaria, Ni Made Ayu Suardani Singapurwa, I Gede Sutapa, Anak Agung Sagung P Putri Risa Andriani, I Gusti Ayu Chinta Dewi Copyright (c) 2023 AJARCDE (Asian Journal of Applied Research for Community Development and Empowerment) https://creativecommons.org/licenses/by-sa/4.0 https://ajarcde-safe-network.org/index.php/index.php/ajarcde/article/view/321 Mon, 11 Sep 2023 09:46:19 +0700 Inspiration by Pop-up Advertising among the Community in Batam and Consumer https://ajarcde-safe-network.org/index.php/index.php/ajarcde/article/view/320 <p>The rapid increase in the use of Information and Communication Technology (ICT) in society has affected significant changes in entertainment media specifically in the field of video games. Advertisements in video games can influence user behavior, particularly in Inspired-To. In order to learn more about Inspired-To and how it can influence the behavior of video game players, the author will administer a questionnaire (N=390) and conduct interviews (N=30) with video game players. The authors of this study discovered that users were contented with the results of pop-up advertisements if the content was entertaining and provided incentives. The author also notes that each of the advertisements is entertaining and that providing incentive benefits can enhance the value of the advertisement. The author discovers that a strong ad value can inspire users to discover something new, which will then inspire them to download the new game advertised by the pop-up ad. This research will assist users in identifying factors that increase the likelihood that they will acquire a new game.</p> Jefry Tan, Diny Anggriani Adnas Copyright (c) 2023 AJARCDE (Asian Journal of Applied Research for Community Development and Empowerment) https://creativecommons.org/licenses/by-sa/4.0 https://ajarcde-safe-network.org/index.php/index.php/ajarcde/article/view/320 Mon, 11 Sep 2023 10:51:17 +0700 Provision of Fermented Coffee Skins as Additional Feed For The Growth of Goats https://ajarcde-safe-network.org/index.php/index.php/ajarcde/article/view/318 <p>Coffee skin is one of the wastes generated from coffee bean processing which is still potentially used as animal feed through the fermentation process, especially for goats as ruminants. Coffee skin fermentation using local micro-organisms (LMO) produces the best quality, and the provision of 10% substitution has a significant effect on the growth of pigs. The purpose of this study was to be able to determine the response to the appearance of prospective parent goats given fermented coffee husk waste as additional feed to their growth before the reproductive phase. The method used in achieving these objectives is the experimental design method using a Completely Randomized Design (CRD) with 4 treatments, namely: without additional coffee husk (Ko), giving coffee skin 5% (K1), 10% (K2), and 15% (K3) and each treatment was repeated 3 times. The basic feed given is in the form of forage mixed with grass and legumes, and coffee skin is given before being given forage. The results showed that giving fermented coffee skins additional feed had a significant effect (P&lt;0.05) on body weight gain. The higher the level of fermented coffee peels the higher the average added weight until the level of 15% (K3) showed the best results with an additional body weight of 211g/day, but not significantly different (P&gt; 0.05) with K1, and K2. From this study, it can be concluded that the provision of fermented coffee skin waste as additional feed has a significant effect on the additional body weight of goats up to a level of 15%.</p> I Dewa Nyoman Sudita, I Gusti Agus Maha Putra Sanjaya, Ni Made Ayu Gemuh Rasa Astiti.

Twelve samples of hardshell capsules were used, among which Eight samples were pure made from pork and some of them adulterated with cow. The samples were detected before using <em>real-time </em>PCR to determine the identity of the samples. All the gelatin samples were measured with the FTIR spectrophotometer in the reflection mode. Spectra were collected in the wavenumber range from 4000-650 cm<sup>-1</sup>. The results show that the PCA model with the data were pre-processed before PCA was performed. The absorbance data from FTIR were pre-processed using <em>Savitsky-Golay</em> smoothing technique and continued with normalization by peak normalize before subjected to PCA. This newly developed method is fast, involves simple sample preparation and is low cost.</p> Ahlam Inayatullah Badrul, M Abdurrahman Munir, I Gusti Riani, R Sa’adah Copyright (c) 2023 AJARCDE (Asian Journal of Applied Research for Community Development and Empowerment) https://creativecommons.org/licenses/by-sa/4.0 https://ajarcde-safe-network.org/index.php/index.php/ajarcde/article/view/317 Tue, 12 Sep 2023 22:12:15 +0700 Low-Cost Solar Energy Harvesting: A Study on Dye-Sensitized Solar Cells Using Inthanin Leaf Extract as a Natural Photosensitizer https://ajarcde-safe-network.org/index.php/index.php/ajarcde/article/view/329 <table width="662"> <tbody> <tr> <td width="393"> <p>The world is actively pursuing renewable energy resources to combat environmental pollution and greenhouse gas emissions caused by the burning of fossil fuels. Solar energy is the most abundant, continuously available form of renewable energy, and dye-sensitized solar cells (DSSCs) are being explored as an alternative to traditional silicon-based solar cells due to their low cost of materials, ease of production, and efficiency. The photoanode is a crucial component in DSSCs, and the main challenges faced by these solar cells are charge recombination and low light harvesting ability. This study aims to investigate the efficacy of natural dyes as the sensitizer for the fabrication of DSSCs. Natural pigments were extracted from Inthanin leaves using the solvent extraction technique. The concentration and composition of the pigment were analyzed through pigment analysis utilizing UV a spectrophotometer. <em>Inthanin</em> has a higher chlorophyll a to b ratio. A higher chlorophyll a to b ratio has been shown to be associated with improved light harvesting and electron transport efficiency. This is because chlorophyll a is more efficient at transferring electrons to the electron transport chain than chlorophyll b. The higher chlorophyll a to b ratio could lead to improved electron transfer to the photoanode. The photoelectric parameters of the DSSC were evaluated using I-V characterization. DSSCs coated with <em>Inthanin</em> dye extract produced a short circuit current density (J<sub>sc</sub>) of 0.02 mA/cm<sup>2</sup>, open circuit voltage (V<sub>oc</sub>) of 0.07 V, fill factor (FF) of 33% and an efficiency (????) of 0.1%.</p> </td> </tr> </tbody> </table> Maria Onyemowo, Yuwalee Unpaprom, Rameshprabu Ramaraj Copyright (c) 2023 AJARCDE (Asian Journal of Applied Research for Community Development and Empowerment) https://creativecommons.org/licenses/by-sa/4.0 https://ajarcde-safe-network.org/index.php/index.php/ajarcde/article/view/329 Fri, 29 Sep 2023 13:03:41 +0700 Empowering KWT Mekar-Sari Kintamani in postharvest handling of Siamese oranges with the application of nanocoating-konjac https://ajarcde-safe-network.org/index.php/index.php/ajarcde/article/view/314 <p>Consumption of Siam Kintamani oranges is currently increasing, driven by public awareness of health. Its bioactive components are beneficial to health, but their quality is rapidly degrading. The Nanocoating-konjac application method is needed to keep oranges fresh. Nanocoating-konjac is a natural preservative solution made from konjac which is applied by immersion method. Village community empowerment is an effort to develop community independence and welfare. KWT Mekar-Sari (partners) is a group of women farmers in the village of Pengejaran, Kintamani District, Bali Province, Indonesia, who need assistance to extend the shelf life of Siamese oranges. Utilization of Nanocoating-konjac as a natural preservative for Siamese oranges can support community service goals, namely improving skills (soft skills and hard skills) as well as forming/developing economically and socially independent communities. Through community service activities partners have the skills, insights in managing natural resources and an entrepreneurial spirit, thereby opening up wider business and marketing opportunities. Community service activities are carried out through training using lecture methods, discussions, demonstrations, questions and answers, while after handling the program an evaluation is carried out. The results of community service showed that of the 20 group members who participated in the activity, 70% had never preserved Siamese oranges, only 30% preserved them in a simple way. After carrying out these activities, all members understand the material and practices carried out and members continue to apply nanocoating to citrus fruits in accordance with what is practiced and then marketed. By utilizing the application of nano-konjac coating on citrus fruits, it provides added value and becomes a source of income for the community</p> Luh Suriati Copyright (c) 2023 AJARCDE (Asian Journal of Applied Research for Community Development and Empowerment) https://creativecommons.org/licenses/by-sa/4.0 https://ajarcde-safe-network.org/index.php/index.php/ajarcde/article/view/314 Fri, 29 Sep 2023 13:26:25 +0700
