PEMANFAATAN PECTIC OLIGOSACCHARIDES (POS) DARI LIMBAH KULIT BUAH SEBAGAI AGEN PROBIOTIK
No full textFood waste menjadi salah satu masalah pangan dari segi produksi ataupun konsumsi. Food waste seperti kulit buah memiliki senyawa turunan pektin berupa pectic oligosaccharides (POS) yang bermanfaat untuk kesehatan. Setiap kulit buah memiliki yield pektin dan POS yang berbeda bergantung sumber dan metode hidrolisis yang dilakukan. Sumber dan metode hidrolisis dapat mempengaruhi karakteristik POS seperti komposisi monosakarida, derajat polimerisasi (DP), dan derajat esterifikasi (DE). POS umumnya memiliki DP yang rendah (DP<10) serta memiliki DE dan komposisi penyusun mono- atau oligosakarida yang berbeda sehingga mempengaruhi potensi POS sebagai prebiotik. Potensi POS ditentukan berdasarkan karakteristik POS agar dapat dimanfaatkan oleh bakteri probiotik. Setiap bakteri uji memiliki kemampuan yang berbeda-beda dalam memanfaatkan komponen POS sebagai sumber C. Hasil penelitian menunjukkan kandungan OGalA pada POS dapat difermentasi menggunakan enzim intra seluler bakteri uji terutama Bacteroides vulgatus hingga menghasilkan asam lemak rantai pendek (SCFA) seperti asam asetat, asam propionat, asam butirat, asam format dan asam laktat. Adanya potensi POS sebagai prebiotik yang berasal dari kulit buah jeruk manis dapat dimanfaatkan sebagai bahan enrichment untuk produk pangan yang tepat guna mengatasi salah satu permasalahan pangan.

HUBUNGAN ANTARA BEBAN KERJA DENGAN STRES KERJA PADA KARYAWAN RADIO X DI MADIUN
Get PDFRadio employees have greater demands and consequences, such as needing to learn technology and create exciting and exclusive shows, thus causing increased work to improve the quality of work. Work stress among radio employees arises due to work overload. This research aims to examine the relationship between workload and work stress among Radio X employees in Madiun. The method used in this research uses a quantitative approach to test the hypothesis. The measuring tools used are the work stress and workload scales to obtain research data. The sampling technique used in this research was total sampling, this was because the number of research subjects was only 80 people. Based on the hypothesis test (Ha) results, the significance value obtained is 0.000, which indicates a significant relationship. Meanwhile, the correlation coefficient value in this study was 0.781, which shows that the correlation between workload and work stress for Radio X employees in Madiun is very strong. This means that as the employee's workload increases, the level of work stress also increases; conversely if the workload decreases, the work stress experienced by the employee will also decrease. One of the main factors that contributes to high levels of work stress is workload that exceeds individual capacity. It is characterized by long hours, unrealistic performance targets, and limited resources required to complete tasks
Personal Political Branding: Framing Pemberitaan Gibran Rakabuming Pada Majalah Tempo Edisi “Ugal-Ugalan Paman Gibran”
Get PDFThe year 2023 marks the beginning of a dynamic political period, with intensive preparations for the contestation of the presidential and vice-presidential elections in 2024. This research explores how Tempo Magazine's news framing in the “Ugal- Ugalan Uncle Gibran” edition shapes the political image of Gibran Rakabuming Raka, particularly in the context of the 2024 vice presidential election. This topic is interesting to research since it highlights the critical role of the media in influencing the political image during the crucial period leading up to the election, where public perception plays a significant role in determining the direction of political support. Using Robert M. Entman's Framing analysis model, this study assesses how Tempo defines the problem, identifies causes, provides moral judgment, and recommends solutions. Using a constructivist qualitative approach, this study examined the printed and digital editions of the magazine to assess how Tempo's framing influenced public perception and Gibran's political branding. The unit of observation and analysis of this research is Tempo Magazine's “Ugal-Ugalan Paman Gibran” print and digital editions. This study found that Tempo framed Gibran's candidacy in the context of legal and ethical violations by labeling him as the “illegitimate son of the Constitution” and highlighting the issues of nepotism and political dynasty as the main elements. The results showed that Tempo Magazine's negative framing significantly affected Gibran's political image and not only impacted public perception of Gibran, but also affected the personal political branding strategy being built ahead of the election. This research contributes to the literature by presenting a new perspective on the role of the media in shaping public opinion and political image. In addition, this research provides a novelty side by providing a perspective on practical implications for improving personal political branding strategies in Indonesia
DIFFERENCES IN BODY FAT MASS AMONG VEGAN AND LACTO-OVO VEGETARIAN GROUPS AGED 15-64 YEARS IN DENPASAR VEGETARIAN COMMUNITY
Get PDFBackground: Excess of fat mass can lead to obesity and increase the risk of non-communicable diseases which will affect a person's quality of life. One of the way to prevent the risk of non- communicable diseases is throughvegetarian diet intervention. According to theory, people on a vegetarian diet have low fat mass. However, it turns out that several studies have shown the opposite results in the form of high fat mass or the incidence of obesity in vegetarian groups. Therefore, researchers want to clarify people's understanding of the relationship between fat mass and a vegetarian diet.Objective: To analyze the differences in fat mass between the vegan and lacto-ovo vegetarian groups aged 15-64 years in Denpasar vegetarian community.Method: The research design is cross-sectional.

ASSOCIATION OF LONG-TERM MEDITERRANEAN DIETARY PATTERN AND DEPRESSIVE MOOD IN OLDER ADULTS: A SYSTEMATIC REVIEW OF COHORT STUDIES
Get PDFDepression is a significant global health concern that occurs frequently among individuals aged 65 and older. In addition to pharmacological therapy and psychotherapy, dietary interventions play a crucial role in the multifactorial, biopsychosocial treatment of psychiatric disorders and could be used as a potential therapeutic target. Increasing evidence is emerging about the important role of the Mediterranean diet (MeDi) in the pathophysiology of mood disorders, particularly depression. This systematic review aims to assess whether long-term adherence to MeDi affects depressive symptoms in the elderly based on published cohort studies. Literature searches are conducted on several databases (PubMed, ProQuest, ScienceDirect, and Google Scholar) with keywords related to “Mediterranean diet”, “depression” and “elderly”. The research was done based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Studies were then screened based on the inclusion criteria, with the result of 3 included cohort studies out of 5,123 identified studies. Study characteristics were extracted and the risk of bias was assessed with the Joanna Briggs Institute Critical Appraisal Checklist for each study. Based on the study analysis, the relationship between adherence to the Mediterranean diet and depression in elderly over time is inconclusive due to conflicting results and limited studies

ANALISIS SOSIAL CALON KUASI PAROKI NGENI, BLITAR : (REKOMENDASI BAGI KEBIJAKAN PASTORAL DI KEUSKUPAN SURABAYA)
Get PDFSocial analysis is a crucial step in the development of a “stasi”(a catholic community who gather for worship in a chapel, usually smaller than a parish) into a quasi-parish or parish. This community service program aims to conduct a social analysis of the stasi under the prospective quasi-parish of Ngeni. The findings of this analysis will be utilized by the Pastoral Center of the Diocese of Surabaya to design initiatives aligned with the needs and aspirations of the community.
The social analysis in this program was conducted in three stages: data collection, observation and interviews, and data interpretation. The team classified the identified issues into three main domains of social processes: socio-economic, socio-cultural, and socio-political. This analysis resulted in strategies that will inform the pastoral policies of the Diocese of Surabaya.
The conclusion of this community service program highlights three main challenges faced by the community: 1) socio-political conditions, such as natural resource conflicts and water crises, which require environmental literacy, legal advocacy, and strengthening village institutions; 2) socio-cultural conditions, including the declining involvement of young generations in the church and inadequate leadership regeneration, which can be addressed through building diaspora networks, skill training, and liturgical guidance; and 3) socio-economic conditions, such as unequal access to education and healthcare, which call for church initiatives to strengthen village institutions, push for development programs, provide Catholic formal education, and collaborate with local leaders to support people with disabilities and the elderlyAnalisis sosial adalah langkah penting yang perlu dilakukan dalam pegembangan dari stasi menuju kuasi paroki atau paroki. Pengabdian masyarakat ini bertujuan untuk membuat analisis sosial atas stasi di bawah calon kuasi paroki Ngeni. Temuan analisis ini selanjutnya akan dimanfaatkan oleh Pusat Pastoral Keuskupan Surabaya untuk membentuk inisiatif yang selaras dengan kebutuhan dan aspirasi masyarakat.
Analisa sosial dalam program abdimas ini dilakukan dalam tiga tahap yaitu, inventaris data, observasi dan wawancara, serta interpretasi data. Tim abdimas mengklasifikasikan persoalan-persoalan dalam tiga bidang utama yang menyusun proses sosial yaitu sosial-ekonomi, sosial-budaya, dan sosial-politik. Analisa ini menghasilkan strategi-strategi yang akan menjadi masukan bagi kebijakan pastoral Keuskupan Surabaya.
Kesimpulan dari program Pengabdian Masyarakat ini menunjukkan tiga tantangan utama yang dihadapi masyarakat, yaitu: 1) kondisi sosial-politik, seperti konflik sumber daya alam dan krisis air, yang memerlukan literasi lingkungan, advokasi hukum, dan penguatan lembaga desa; 2) kondisi sosial-budaya, termasuk menurunnya generasi muda yang terlibat di gereja dan kurangnya regenerasi pengurus, yang dapat diatasi melalui pembangunan jaringan diaspora, pelatihan keterampilan, dan pendampingan liturgi; serta 3) kondisi sosial-ekonomi, seperti akses yang tidak merata terhadap pendidikan dan kesehatan, yang membutuhkan inisiatif gereja dalam memperkuat lembaga desa, mendesak program pembangunan, dan menyediakan pendidikan formal Katolik, serta kerja sama dengan kader lokal untuk mendukung kaum difabel dan lansia
