Abstract

Brokoli (Brassica oleracea var. italica) merupakan sayuran fungsional yang diketahui mengandung berbagai senyawa bioaktif dengan potensi nutrisi dan farmakologis yang penting. Penelitian ini bertujuan untuk memprofilkan senyawa bioaktif ekstrak brokoli yang dibudidayakan dengan perlakuan pemupukan berbeda, yaitu kontrol, pupuk kandang, dan pupuk biokonversi maggot black soldier fly (BSF). Sampel brokoli diekstraksi menggunakan etanol 80%, kemudian dianalisis dengan LC-MS/MS untuk mengidentifikasi dan mengkuantifikasi komposisi metabolit. Hasil penelitian menunjukkan bahwa perlakuan pupuk biokonversi maggot menghasilkan pertumbuhan tanaman yang lebih baik, meliputi tinggi tanaman, jumlah daun, biomassa segar dan kering, serta persentase berbunga dibanding perlakuan lain. Selain itu, perlakuan ini juga menghasilkan metabolit yang lebih beragam dengan kelimpahan lebih tinggi, terutama golongan fenolik, terpenoid, piridazin, dan indol. Beberapa senyawa utama yang teridentifikasi antara lain Indole-3-Propionic Acid dan N(1),N(8)-Bis(Coumaroyl)Spermidine(1+), serta turunan klorofil seperti pyropheophorbide-a yang ditemukan dengan kelimpahan signifikan. Temuan ini menunjukkan bahwa pupuk biokonversi maggot BSF mampu meningkatkan pertumbuhan sekaligus profil metabolit sekunder brokoli, sehingga berpotensi sebagai strategi pemupukan ramah lingkungan untuk meningkatkan kualitas nutrisi dan fungsional tanaman ini.

Abstract

Introduction: Sarung Goyor is one of the popular textile industries in Indonesia. The manual production process results in the release of a high number of dust particles into the air, including rayon fibers, which are a major component of the fabric. Inhaling fine fibers causes respiratory tract irritation and impaired lung function. There hasn't been much research exploring rayon dust exposure related to small-scale weaving crafts. This study aims to find a relationship between rayon fibers and lung function among sarong weavers in Indonesia. Methods: A cross-sectional study was carried out at the Sarung Goyor Industry Center North Wanarejan, Pemalang, involving 101 male weavers. The data collected includes total dust and inhalable dust levels, lung function values, and ventilation area.Dust sampling was performed using the Hi-Q HVP-2000 and SKC PCXR 8000, and lung function values were measured using the Spiro LAB III according to ATS standards. Data were analyzed using the Kolmogorov-Smirnov test and correlation test. Results and Discussion: 78% of respondents experienced impaired lung function, obstructive 22%, restrictive 46.5%, and mixed 18.8%. There is a strong relationship between age and restriction (p = 0.001) as well as inhaled dust and restriction (p = 0.026). A statistically significant inverse association was identified between ventilation area and the presence of obstructions. Conclusion: Rayon has a significant impact on lung function, causing restriction and obstruction over time. Therefore, it is essential to advocate for improved workplace ventilation and the consistent use of protective masks among weavers.

Abstract

Diabetes has steadily increased in the last two decades. Studies show people's behavior in managing diabetes is very complex and influenced by cultural beliefs and values. This research describes the understanding, belief, and related behaviors toward the diabetes mellitus of Diabetes Mellitus type II patients in the Eastern region of Indonesia. The researchers grouped the participants in a semi-structured focus group. The group consisted of 12 participants aged between 45 and 55 years old. The focused group was useful to obtain the perspective, experience, and attitude about diabetes. The researchers analyzed the qualitative data with the Health Belief Model as the analytical framework to identify the patterns and the main findings. The analysis results found five primary themes related to understanding, belief, and diabetic behavior. The themes were: The diabetic understanding of the Eastern regional communities such as the cultural problem and the role of local beliefs to treatment diabetes. The tradition and the modern medical approach, the challenges of healthy lifestyle practice, the psychological impacts of diabetes on health, and the expectations and the challenges of the local health system.The researchers expect the findings could be the principle for developing more directed and effective interventions
