Abstract

Red dragon fruit (Hylocereus polyrhizus) based jam products have high potential, but consumer acceptance is still limited due to sensory constraints that arise when dragon fruit skin is used as an additional ingredient. This study aimed to evaluate the sensory quality of red dragon fruit jam by adding dragon fruit peel, using statistical and food chemistry approaches. Organoleptic tests were conducted on 30 untrained panellists to assess four main attributes: colour, texture, odour, and taste, using a 9-point hedonic scale. Data were analyzed using descriptive statistics, the Shapiro-Wilk normality test, the one-sample t-test, and cronbach's alpha reliability test. The results showed that colour and texture were not significantly different from the "like" threshold value ( = 7), while odour and taste showed significant differences (p 0.05). Cronbachs alpha value of 0.673 indicated moderate consistency of assessment. The food chemistry perspective explain that the less preferred odour and taste attributes are thought to be caused by secondary metabolite compounds such as tannins in dragon fruit peel, which can produce a bitter sensation or foreign odour. Approaches such as blanching and formulation adjustments can be strategies to improve sensory quality. This study contributes to developing innovative and sustainable dragon fruit-based food products

Abstract

The lack of attention given in scholarly research to the particular requirements of Public Administration has resulted in a knowledge deficit to suit students' interests in this discipline. Prior research has predominantly examined the quantitative dimensions of vocabulary acquisition while neglecting to adequately consider the qualitative aspects, including comprehension and language use, in a contextually appropriate manner. This study aims to fill in these knowledge deficits by investigating vocabulary themes or topics related to Public Administration, evaluating existing instructional approaches and challenges, and suggesting enhancements to bolster students' English language proficiency in Public Administration. The study employs a qualitative methodology, including an open-ended questionnaire and in-depth interviews with four lecturers and 100 first-year students from three universities in South Sulawesi, Indonesia. The findings revealed that the English for Public Administration curriculum requires a diverse vocabulary of topics from administration, management, and governance to more nuanced areas such as economics, finance, taxation, social and ethics, technology and digitalization, leadership, and regulation and law. Various teaching and assessment strategies regarding instructional methods, including interactive and collaborative methods, technology integration, and contextual learning, suggest the importance of engaging students with diverse and practically relevant content to prepare them for the multifarious nature of public sector roles. Students, however, found some challenges in the complexity of the Public Administration vocabulary, highlighting the need for tailoring educational strategies, such as project-based learning and vocabulary reinforcement techniques, to overcome these obstacles. The study's findings have substantial implications for policymakers, curriculum developers, and lecturers specializing in public administration education.

Abstract

Pangan fungsional saat ini merupakan pangan yang perkembangannya maju pesat di dunia, seiring dengan semakin tingginya permintaan dan kesadaran masyarakat tentang kesehatan. Berbagai produk pangan fungsional dapat dihasilkan dengan melimpahnya sumber komponen bioaktif baik pada hasil panen pertanian, tanaman herbal, produk pangan hewani (susu), dan mikroorganisme non-patogen (Lactobacillus) yang dapat meningkatkan kesehatan karena dapat berefek sebagai antioksidan, antiradang, antidiabetes, dan lain sebagainya. Teknologi farmasi merupakan salah satu ilmu yang dapat diterapkan untuk menghasilkan produk pangan fungsional yang berkualitas. Oleh karena itu, kegiatan pengabdian masyarakat ini dilaksanakan untuk memperkenalkan teknologi farmasi khususnya teknik pengawetan bahan pangan kepada masyarakat desa Tosale agar dapat mengolah hasil pertanian menjadi produk pangan fungsional yang berkualitas dan memiliki nilai ekonomis yang lebih tinggi. Metode yang digunakan dalam kegiatan ini yaitu melalui edukasi atau penyuluhan. Tahapan penyuluhan dalam kegiatan ini yaitu pemaparan materi melalui materi presentasi, booklet dan video edukasi untuk menyampaikan informasi yang dibutuhkan untuk meningkatkan pemahaman masyarakat Desa Tosale terhadap edukasi yang telah diberikan. Kegiatan ini dapat meningkatkan pengetahuan masyarakat Desa Tosale tentang pangan fungsional, manfaatnya dalam peningkatan kesehatan dan pencegahan penyakit serta cara menghasilkan produk pangan fungsional yang berkualitas. Hasil yang telah diperoleh dari pelaksanaan kegiatan pengabdian kepada masyarakat ini berupa luaran kegiatan dalam bentuk booklet yang berisi informasi mengenai jenis-jenis teknik pengawetan dan metode pengawetan bahan pangan yang telah dibagikan kepada masyarakat saat penyuluhan. Booklet ini menjadi media informasi yang dapat diterapkan oleh masyarakat setempat untuk mencoba membuat produk pangan dari hasil perkebunan di Desa Tosale untuk dikonsumsi sendiri maupun dijadikan usaha rumah tangga. Selain itu, hasil pelatihan berupa peningkatan pengetahuan peserta pelatihan diukur melalui nilai rata- rata pre-test yaitu sebesar 70,77 dibandingkan dengan nilai rata-rata post-test yaitu 94,62. Hasil ini menunjukkan adanya peningkatan persentasi nilai sebesar 23,85%.

Abstract

Bio-batteries are one alternative as well as a solution to the limited use of electrical energy. Batteries that are widely used today are sourced from chemicals in the form of heavy metals such as mercury, lead, cadmium, and nickel, which can pollute the environment if not disposed of properly. Efforts to reduce the use of chemicals that pollute the environment need innovation to overcome the problem. This study aims to determine the formula for bio-batteries that have a long life. The method used is to mix banana peel and breadfruit peel that has been fermented with variations of b/vv (g/mmL) with a composition of 0, 25, 50, 75, and 100% at each concentration. The parameters observed in this study were pH and voltage measurements during the fermentation process for 7 days, and the bio-batteries that had been made were tested for potential differences in electric current, power, resistance, and durability. As a result, the optimum condition of the bio-battery was obtained in a mixture of 75% banana peel compared to 25% breadfruit peel by producing a potential difference of 1.37 V, an electric current of 1.5 mA, and a power of 0.68 mW. A bio-battery with a composition of 75% banana peel compared to 25% breadfruit peel can last a maximum of 31 hours and 28 minutes when used on a wall clock.

Abstract

Indonesia relating to land issues. The meaning of public interest in land acquisition which is expected to be able to help realize justice, prosperity and welfare for the community turns out that in its implementation it actually causes conflict because it is not in accordance with the principles of balance and justice. The problems that the research tries to answer are: (1) What is meant by public interest according to the applicable laws and regulations? (2) How is the reconstruction of the meaning of public interest in land acquisition for development in the public interest based on the principles of balance and justice? To answer this problem, the paradigm used in this research is the constructivism paradigm, supported by the theory of the rule of law, the theory of legal interpretation, and the theory of corrective justice. The methodology in this research uses sociolegal methodology. From this research, it was found that the meaning of public interest in the Basic Agrarian Law apparently changed inconsistently in the derivative regulations that followed. The correct meaning of public interest is the interest of the nation, state, and society, which continues to pay attention to individual interests and must be realized jointly by the central or regional government and the community and used as much as possible for prosperity, justice, and happiness for society as a whole. The recommendation from this research is the need for consistency in the formation of laws and regulations in accordance with the principles of the rule of law. In addition, the government is expected to pay attention to the principles of balance and justice in the land acquisition process for development in the public interest. The current meaning of public interest needs to be reconstructed according to the objectives of UUPA.
