Abstract

Floating net cages (KJA) aquaculture is an important livelihood source for local community, but it also contributes to eutrophication in Rawa Pening Lake. So, it is necessary to ensure that KJA management is carried out based on the sustainable development principles to minimize the environmental impacts. This study aims to assess the sustainability status of KJA management in Rawa Pening Lake from the ecological dimension. Data were collected through interviews, direct observation, direct measurement and literature study based on following attributes; water quality, water fertility, environmental conditions, biosecurity and fish health. Then, data that has been scored were analyzed by Multi-Dimensional Scaling (MDS) using the RAPFISH application embedded in Ms. Excel). The results showed the KJA sustainability index is 49,567 (poor sustainability category). The most significant attribute of KJA sustainability is water nutrient content, i.e. N:P ratio (leverage = 4,129). It is concluded that the management of KJA in Rawa Pening Lake has been not carried out based on sustainable aquaculture management principles. Therefore, management strategies focusing on controlling water nutrient levels are urgently required to ensure the sustainability of KJA in Rawa Pening Lake.

Abstract

The purpose of this study was to determine the effect of tempo elements through the creation of new music played to patients preoperatively to reduce anxiety levels. Anxiety in preoperative patients can be a risk factor for increased postoperative anxiety if not previously given appropriate intervention. Anxiety can cause aggressive reactions and increase the patient's experience of distress and difficulty with pain management. Music creation with tempo manipulation and sedative concepts is used to reduce the anxiety level of preoperative patients because it has a character that can provide a relaxing sensation, especially slow tempo and simple melody (William, 2018). One-shot case study pre-experimental research method was used to determine the therapeutic effect of weightless music. Five participants consisted of randomly selected preoperative patients aged 18-40 years. Each participant listened to slow tempo music for 15 minutes as a form of non-pharmacological intervention to reduce anxiety and there was no placebo. The results show that there is a decrease in anxiety levels in preoperative patients and 80% of participants thought that tempo is the most influential musical element. Tempo with a speed between 50-60 bpm can cause a pleasant sensation for subjects who are treated to listening to music. Based on the experimental results, the effect of music on reducing the level of preoperative anxiety then created new musical works.Efek Terapeutik Musik Weightless dalam Menurunkan Kecemasan Pasien Praoperasi AbstrakPenelitian ini bertujuan untuk mengetahui pengaruh unsur tempo melalui penciptaan musik baru yang diperdengarkan kepada pasien praoperasi dalam menurunkan tingkat kecemasan. Kecemasan pada pasien praoperasi dapat menjadi faktor risiko meningkatnya kecemasan pascaoperasi apabila tidak diberikan intervensi yang tepat sejak awal. Kecemasan dapat memicu reaksi agresif serta meningkatkan pengalaman distres pasien dan kesulitan dalam pengelolaan nyeri. Penciptaan musik dengan manipulasi tempo dan konsep sedatif digunakan untuk menurunkan tingkat kecemasan pasien praoperasi karena memiliki karakter yang mampu memberikan sensasi relaksasi, terutama musik dengan tempo lambat dan melodi sederhana (William, 2018). Penelitian ini menggunakan metode praeksperimen dengan desain one-shot case study untuk mengetahui efek terapeutik musik weightless. Partisipan penelitian berjumlah lima orang pasien praoperasi berusia 18–40 tahun yang dipilih secara acak. Setiap partisipan mendengarkan musik bertempo lambat selama 15 menit sebagai bentuk intervensi nonfarmakologis untuk menurunkan kecemasan, tanpa pemberian plasebo. Hasil penelitian menunjukkan adanya penurunan tingkat kecemasan pada pasien praoperasi, dan sebanyak 80% partisipan menyatakan bahwa tempo merupakan unsur musik yang paling berpengaruh. Tempo dengan kecepatan antara 50–60 bpm mampu menimbulkan sensasi menyenangkan bagi subjek yang menerima perlakuan mendengarkan musik. Berdasarkan hasil eksperimen tersebut, disimpulkan bahwa musik berpengaruh dalam menurunkan tingkat kecemasan praoperasi, yang selanjutnya menjadi dasar penciptaan karya musik baru.

Abstract

Burns are tissue damage or loss caused by contact with heat sources such as fire, hot water, chemicals, electricity and radiation. The grape plant has an activity of pharmacological effects, which are mainly present in its seeds and fruits. Grape seed extract containing proanthocyanidin can help wound healing by promoting neovascularization, extracellular matrix remodeling, fibrolastic cell migration and differentiation. Aloe vera leaves can be used to treat skin lesions, such as burns, irradiation damage and ischemic ulcers. In addition to being a hydrating and skin- protecting agent, this gel also has healing, analgesic, and anti-inflammatory activities because aloe vera contains vitamins C and E, essential amino acids, and polysaccharides that stimulate tissue growth and cell regeneration. The objective is to determine the effectivity of burn wound repair using grape seed extract and aloe vera. This research used 24 white rats weighing 150 to 200g that divided into 4 groups, positive control group, negative control group, 10% grape seed extract treatment group, and 10% aloe vera extract treatment group. This study used an experimental method with True Experimental design with Randomized Post-test only Control Group Design, by giving 10% concentration of grape seed extract and aloe vera extract with 10% concentration to rats that has been burnt.

Abstract

Music-based interventions have been widely explored as non-invasive approaches to emotional regulation and anxiety reduction. Within this context, alternative tuning frequencies—particularly 432 Hz and 528 Hz—are frequently used in therapeutic and wellness practices and are often claimed to exert distinct psychophysiological effects. However, empirical evidence supporting differential neural responses to these frequencies remains limited, and existing claims are rarely grounded in direct measurements of brain activity. This study aimed to empirically examine whether music tuned to 432 Hz and 528 Hz produces differential effects on neural oscillatory activity, as measured by brainwave patterns, with particular attention to indicators associated with relaxation and meditative states. A quantitative repeated-measures design was implemented. Ten undergraduate music education students (aged 19–21 years) from the Indonesian Institute of the Arts (ISI) Yogyakarta participated. Each participant listened to the same musical composition presented in two tuning conditions (432 Hz and 528 Hz) in counterbalanced order. Neural activity was recorded using a single-channel EEG device (Neurosky MindWave), which provides spectral estimates of canonical brainwave bands. Delta-band amplitude was selected a priori as the primary outcome measure. Differences between tuning conditions were analyzed using paired-sample t-tests, supplemented by bootstrapping to address the small sample size. Both tuning conditions elicited increased delta-band dominance during music listening. However, no statistically significant difference in delta-band amplitude was observed between the 432 Hz and 528 Hz conditions (t(9) = −1.29, p = 0.229). Bootstrapped confidence intervals corroborated the absence of a reliable frequency-dependent effect. Under controlled within-subject conditions and using single-channel EEG-derived spectral estimates, no evidence was found for differential modulation of delta-band activity between music tuned to 432 Hz and 528 Hz. The results suggest that neural responses are more strongly driven by general musical engagement than by tuning frequency per se. Methodologically, the study highlights both the utility and limitations of low-density EEG for probing music-related neural oscillations and supports the need for future work employing higher spatial resolution EEG, baseline-corrected spectral analyses, and larger samples to test frequency-specific hypotheses with greater sensitivity.

Abstract

Background: Type 2 Diabetes Mellitus (T2DM) is a significant health issue in Indonesia, where management relies heavily on patient dietary adherence. However, adherence levels are often suboptimal. This study aimed to identify the factors associated with dietary adherence among T2DM patients at a major hospital in Medan, Indonesia. Methods: This cross-sectional study was conducted in December 2024 at Royal Prima General Hospital, involving 64 T2DM patients selected through total sampling. Data on demographic characteristics, knowledge, family support, and healthcare provider (HCP) support were collected via structured questionnaires. Dietary adherence was the dependent variable. Data were analyzed using chi-square tests and multivariate logistic regression. Results: A slight majority of patients (53.1%) were adherent to their diet. Multivariate analysis identified age as the most dominant predictor, with patients aged ≥45 years being 18.9 times more likely to be adherent than younger patients (AOR = 18.935, p=0.004). Male gender was also a significant predictor of higher adherence (AOR = 7.652, p=0.01). Paradoxically, good knowledge (AOR = 0.161) and HCP support (AOR = 0.109) were significantly associated with lower odds of adherence. Education and employment status showed no significant association. Conclusion: Age is the most critical factor influencing dietary adherence among T2DM patients in this cohort, with older individuals demonstrating significantly better compliance. Interventions should specifically target younger patients and women, who are at higher risk for non-adherence.
