Mental health disorders, particularly depression and anxiety, remain major contributors to the global burden of disease and disability. Socioeconomic inequality, including differences in Gross National Income (GNI) per capita, is considered an important factor influencing mental health outcomes. This study aimed to analyze the relationship between GNI per capita and the prevalence of depression and anxiety disorders globally using data from the Global Burden of Disease (GBD) 2023 database. A descriptive ecological study design was conducted using secondary data from 187 countries and regions. Data were analyzed using descriptive statistics, Spearman correlation tests, and regional comparative analysis with ANOVA. The results showed substantial disparities in mental health burden and income distribution across regions. Africa had the highest average prevalence of depression, while Asia showed the greatest variability in anxiety disorders. A significant negative correlation was found between depression prevalence and income levels (r = -0.213; p = 0.003), indicating higher depression rates in lower-income countries. However, anxiety showed a weak and insignificant relationship with income (r = -0.079; p = 0.281). These findings emphasize the need to reduce socioeconomic inequalities and strengthen mental health systems through integrated healthcare services and multisectoral policies.

Low courage in arguing and high communication apprehension often become major obstacles for high school students when facing academic presentations. This Community Service (PkM) program aims to strengthen students' communicative rhetoric skills and public speaking abilities at SMA Negeri 11 Makassar. Based on a needs assessment, partner students need techniques for persuasive public speaking, self-evaluation tools for their communication performance, and strategies for managing mental anxiety. The program was carried out through a practice-based reflective workshop involving 25 students from the school's intra-organizational board. Quantitative evaluation results showed a significant improvement in students' speaking competence, with the average score increasing from 58.4 (pre-test) to 86.2 (post-test). This result recorded an increase in the score difference by 27.8 points, which is equivalent to a competence growth of 47.6%, with the students' classical completeness rate reaching 92%. Qualitatively, observations and interviews confirmed changes in students' speaking behavior, which became more organized, expressive, and varied, and they were able to reduce anxiety independently. A tangible output of this activity is the Pocket Guide for Practical Public Speaking Based on Reflective Practice for partner students.

This community-based project aimed to analyze the cash management system of the micro, small, and medium enterprise (MSME) Bakpia Juwara Satoe and develop recommendations to improve the company's financial performance. Cash management is a crucial but often overlooked aspect of MSME financial management, which can lead to cash flow problems, inaccurate record keeping, and poor management decisions. The methodology used included qualitative data collection through direct observation, in-depth interviews, and financial statement analysis. The project findings revealed that Bakpia Juwara Satoe lacked a functioning cash management system. There was no separation between cash receipts and disbursements, no standardized system for handling cash, and transaction recording remained manual and inconsistent. As part of the project, standard operating procedures (SOP) for cash management were developed, financial accounting training was conducted, and support was provided in creating simple cash flow statements. Following the implementation of these measures, record accuracy increased by 78%, and cash losses were reduced. It was determined that the implementation of efficient cash management contributed significantly to the improvement of Bakpia Juwara Satoe's financial performance.

Mangrove forests are high-value coastal ecosystems that have the potential to be developed as sustainable ecotourism destinations. This study aims to analyze the development of Mangrove Forest Tourism in Kampung Kayu Ara Permai, Sungai Apit District, Siak Regency based on the three pillars of sustainable tourism of the World Tourism Organization (UNWTO), namely environmental, economic, and socio-cultural sustainability. The method used is a descriptive qualitative approach through literature studies and semi-structured interviews with regional managers. The results of the study show that this area has a good mangrove ecosystem with nine species and an average Tourism Suitability Index (IKW) of 76.89% (Suitable/S2 category). From an economic perspective, eight non-timber forest products (NTFPs) downstream products and community-based homestay models have created an equitable distribution of benefits for residents. The socio-cultural dimension is supported by the authenticity of the coastal Malay tradition that is still preserved. However, the three dimensions face challenges in the form of the absence of protection regulations, the absence of a government fixed budget, and low public participation in management evaluation. This study recommends the issuance of regional regulations, the establishment of tourism BUMDes, and the strengthening of community participation as the foundation for sustainable ecotourism development.  

Irrational drug use remains a common health problem in the community, including the use of medications without following dosage instructions, discontinuation of treatment before completion, the use of antibiotics without prescriptions, and improper drug storage.

Pressure sensitive labels (PSLs) made of polyethylene (PE) white are widely used in the packaging industry due to their flexibility, moisture resistance, and ease of application on various substrates. This study aimed to examine the effect of glossy and matte lamination on the tensile strength and color difference (ΔE) of PE white PSLs. An experimental method was employed, with tensile testing conducted using a universal testing machine (UTM) in accordance with ASTM standards and color measurement performed using a spectrodensitometer based on the CIE Lab system. The samples were divided into three treatment groups, namely no lamination, glossy lamination, and matte lamination, with ink coverage controlled at two design conditions, full ink and minim ink. The results indicated that lamination type significantly affected both the mechanical and visual characteristics of the labels. In the tensile strength test, the highest mean value was obtained by one treatment group, indicating superior resistance to tensile loading. In terms of color stability, higher ΔE values indicated greater color change and lower lightfastness, whereas lower ΔE values reflected better color retention. Overall, the findings show that the combination of lamination type and ink coverage influences the performance of PE white PSLs in both mechanical strength and color stability.

Penelitian ini bertujuan untuk mengkarakterisasi tingkat toksisitas ekstrak etanol 90% daun trembesi (Samanea saman) terhadap larva udang (Artemia salina) menggunakan metode Brine Shrimp Lethality Test (BSLT) dengan pendekatan Reed-Muench dan analisis probit. Penelitian ini merupakan penelitian eksperimental dengan rancangan post-test only control group design. Larva Artemia salina digunakan sebagai organisme uji karena memiliki sensitivitas tinggi terhadap senyawa toksik dan sering digunakan sebagai indikator awal aktivitas bioaktif. Ekstrak diuji pada berbagai konsentrasi bertingkat untuk mengamati persentase mortalitas larva setelah 24 jam perlakuan. Hasil penelitian menunjukkan bahwa peningkatan konsentrasi ekstrak berbanding lurus dengan peningkatan jumlah kematian larva, yang mengindikasikan adanya hubungan dosis-respons yang jelas. Nilai LC₅₀ yang diperoleh dengan metode Reed-Muench adalah sebesar 567,02 ppm, sedangkan dengan analisis probit diperoleh nilai LC₅₀ sebesar 581,0319 ppm. Perbedaan nilai ini disebabkan oleh perbedaan pendekatan analisis, di mana metode probit dinilai lebih akurat karena melibatkan transformasi statistik yang lebih kompleks. Berdasarkan klasifikasi toksisitas BSLT, nilai LC₅₀ sebesar 581,0319 ppm termasuk dalam kategori sangat toksik (LC₅₀ < 30 ppm). Tingginya tingkat toksisitas ekstrak diduga berkaitan dengan kandungan metabolit sekunder seperti flavonoid, saponin, dan tanin yang memiliki aktivitas sitotoksik. Hasil penelitian ini menunjukkan bahwa ekstrak etanol 90% daun trembesi memiliki potensi bioaktivitas yang tinggi dan berpeluang untuk dikembangkan lebih lanjut sebagai sumber senyawa bioaktif dalam bidang farmasi maupun bioteknologi.

Pemurnian vitamin E dari berbagai sumber bahan alami dan limbah agroindustri terus berkembang seiring meningkatnya kebutuhan industri pangan, nutraseutikal, kosmetik, dan farmasi. Berbagai metode pemurnian telah diterapkan meliputi saponifikasi, ekstraksi menggunakan pelarut, dan distilasi molekuler. Studi ini mengkaji secara sistematis perkembangan metode pemurnian vitamin E dari berbagai sumber serta mengevaluasi keunggulan, keterbatasan, serta prospek penerapan teknologi yang lebih berkelanjutan. Penelusuran literatur dilakukan terhadap publikasi dalam 10 tahun terakhir yang diperoleh dari jurnal nasional dan internasional. Hasil kajian menunjukkan bahwa sumber alami vitamin E banyak terdapat pada minyak nabati, sedangkan sumber dari limbah agroindustri dengan kandungan vitamin E tertinggi diperoleh pada Palm Fatty Acid Distillate (PFAD). Kandungan vitamin E yang bervariasi tergantung dari jenis bahan baku, kondisi proses, dan metode pemurnian yang digunakan. Studi komparatif terkait potensi kandungan vitamin E pada bahan alam dan limbah agroindustri lokal Indonesia masih terbatas, khususnya yang mempertimbangkan variasi varietas genetik. Dari aspek teknik pemurnian, metode ekstraksi konvensional memerlukan beberapa tahapan proses sehingga perlu ditinjau dari sisi efisiensi operasional dan keekonomian. Hasil kajian menunjukkan penggunaan green solvent seperti ekstraksi dengan scCO2 dan DES yang berpotensi meningkatkan keamanan proses dan keberlanjutan lingkungan. Pengembangan metode pemurnian yang efisien, ekonomis, dan ramah lingkungan menjadi kunci dalam mendukung pemanfaatan berbagai sumber vitamin E secara berkelanjutan.

Results show that the best product concepts are Concept 4 and Concept 8, characterized by natural lerak surfactant, active ingredient concentration above 15%, pH of approximately 6, citrus/lemon scent, and pump bottle packaging. The production process consists of preparation, mixing, boiling, addition of thickener, cooling, pressing, filtering, and packaging, with a total production time of 142.05 minutes for two 500 ml products. Total production cost is Rp65,184, with a cost of goods sold (COGS) of Rp32,592 per unit and a selling price of Rp34,000 per unit.

Prasman (Peperomia pellucida) merupakan tanaman obat yang diketahui mengandung berbagai senyawa metabolit sekunder seperti alkaloid, flavonoid, saponin, tanin, dan terpenoid yang berpotensi memiliki aktivitas biologis. Penelitian ini bertujuan untuk mengetahui tingkat toksisitas ekstrak metanol batang prasman terhadap mortalitas larva udang (Artemia salina L.) menggunakan metode Brine Shrimp Lethality Test (BSLT). Penelitian dilakukan secara eksperimental dengan memberikan ekstrak metanol batang prasman pada berbagai konsentrasi, yaitu 10, 100, 500, 1000, 5000, dan 10000 ppm serta kontrol. Parameter yang diamati adalah persentase mortalitas larva setelah 24 jam perlakuan. Data dianalisis menggunakan metode interpolasi dan analisis probit untuk menentukan nilai LC₅₀. Hasil penelitian menunjukkan bahwa peningkatan konsentrasi ekstrak menyebabkan peningkatan mortalitas larva secara bertahap hingga mencapai 100% pada konsentrasi 10.000 ppm. Perhitungan LC₅₀ dengan metode interpolasi menghasilkan nilai 680,2 ppm pada pengujian pertama dan 529,66 ppm pada pengujian duplo. Analisis probit pada pengujian duplo menghasilkan nilai LC₅₀ sebesar 198,97 ppm. Nilai LC₅₀ yang berada di bawah 1000 ppm menunjukkan bahwa ekstrak metanol batang prasman bersifat toksik terhadap larva Artemia salina dengan kategori moderat atau racun sedang. Aktivitas toksik tersebut diduga berasal dari kandungan metabolit sekunder yang terdapat dalam batang prasman seperti Flavonoid, saponin, tanin dan minyak atsirinya. Dengan demikian, ekstrak metanol batang prasman berpotensi sebagai sumber senyawa bioaktif yang dapat dikembangkan lebih lanjut dalam bidang farmasi, khususnya sebagai kandidat antikanker, antimikroba, dan bioinsektisida alami.

Esophageal atresia with tracheoesophageal fistula is a congenital anomaly requiring early diagnosis and prompt surgical correction. Gross type D esophageal atresia, characterized by both proximal and distal tracheoesophageal fistulas, is an exceedingly rare variant that poses significant diagnostic and operative challenges. We report a case of a full-term female neonate with a birth weight of 3,200 grams who presented with hypersalivation since the first day of life, accompanied by coughing and choking during feeding. Orogastric tube insertion failed, with the tube arrested at approximately 15 cm. The patient was referred with a diagnosis of neonatal pneumonia and suspected esophageal atresia with tracheoesophageal fistula. Physical examination revealed tachypnea, chest wall retraction, and respiratory distress requiring ventilatory support. Babygram demonstrated the orogastric tube tip arrested at the proximal esophageal pouch with distal gastrointestinal air. Contrast esophagography confirmed proximal esophageal atresia at the upper thoracic level with suspected proximal fistula. Associated findings included bilateral pneumonia, right upper lobe atelectasis, and vertebral anomalies suggestive of VACTERL association. Intraoperative findings confirmed Gross type D esophageal atresia with proximal and distal tracheoesophageal fistulas. Both fistulas were excised, followed by primary esophageal anastomosis and transanastomotic nasogastric tube placement. Gross type D esophageal atresia is a rare congenital anomaly that should be considered in neonates presenting with hypersalivation, failed orogastric tube insertion, and respiratory distress. Anatomical subtype confirmation relies on intraoperative findings. Early surgical repair can be performed successfully; however, associated anomalies necessitate careful long-term follow-up.

Demam Berdarah Dengue (DBD) merupakan salah satu penyakit menular yang masih menjadi masalah kesehatan masyarakat Indonesia. Data nasional Kementerian Kesehatan RI tahun 2024 mencatat 257.271 kasus dengan 1.461 kematian, sedangkan hingga 23 Juni 2025 dilaporkan 78.646 kasus dan 346 kematian. Penggunaan larvasida sintetis dapat menimbulkan resistensi dan dampak negatif terhadap lingkungan. diperlukan alternatif larvasida yang berasal dari bahan alami, contohnya serai dapur (Cymbopogon citratus) yang diketahui mengandung senyawa aktif seperti sitronelal, geraniol, flavonoid, saponin, dan tanin. Penelitian ini bertujuan untuk mengetahui efektivitas ekstrak serai dapur (Cymbopogon citratus) terhadap mortalitas larva Aedes aegypti. Penelitian ini merupakan penelitian eksperimental laboratorik dengan rancangan post-test only control group design. Larva Aedes aegypti instar III–IV dibagi menjadi lima perlakuan yaitu ekstrak serai dapur konsentrasi 10%, 20% dan 30%, kontrol positif (Abate), serta kontrol negatif. Setiap kelompok terdiri atas empat kali pengulangan dengan 25 larva setiap pengulangan. Pengamatan mortalitas larva dilakukan pada 1 jam, 3 jam, 6 jam, dan 24 jam setelah perlakuan. Data dianalisis menggunakan uji Kruskal-Wallis dan uji Mann-Whitney. Hasil penelitian menunjukkan bahwa mortalitas larva meningkat seiring dengan peningkatan konsentrasi ekstrak dan lamanya waktu paparan. Pada pengamatan 24 jam, seluruh konsentrasi ekstrak menunjukkan mortalitas sebesar 100%, sedangkan kontrol negatif sebesar 2%. Analisis statistik menunjukkan terdapat perbedaan yang signifikan pada mortalitas larva Aedes aegypti antar kelompok perlakuan (p<0,05). Berdasarkan Hasil Penelitian, dapat disimpulkan ekstrak serai dapur (Cymbopogon citratus) efektif terhadap mortalitas larva Aedes aegypti sebagai larvasida nabati dalam pengendalian vektor DBD.

Transformasi digital administrasi pertanahan di Indonesia melalui Peraturan Menteri Agraria dan Tata Ruang/Kepala Badan Pertanahan Nasional Nomor 1 Tahun 2021 telah mengubah sistem pendaftaran tanah dari berbasis dokumen fisik menjadi sistem elektronik. Perubahan ini bertujuan untuk meningkatkan efisiensi, transparansi, dan kepastian hukum dalam pelayanan pertanahan.

Kendala yang dihadapi meliputi gangguan sistem, keterbatasan infrastruktur digital, serta rendahnya literasi digital masyarakat. Upaya yang dilakukan antara lain penguatan sistem keamanan, peningkatan kompetensi sumber daya manusia, serta sosialisasi kepada masyarakat. Sertipikat tanah elektronik memiliki kekuatan pembuktian yang sama dengan sertipikat fisik sepanjang diterbitkan sesuai prosedur dan menggunakan tanda tangan elektronik tersertifikasi.

Aerobic capacity, commonly measured by maximal oxygen uptake (VO₂max), is a key indicator of physical fitness and athletic performance, particularly in endurance sports. Recent attention has focused on the role of respiratory muscle function in supporting exercise performance, as respiratory muscle fatigue during high-intensity or prolonged activity may reduce ventilatory efficiency and exercise tolerance. This literature review aims to examine current evidence regarding the effects of Respiratory Muscle Training (RMT), including Inspiratory Muscle Training (IMT), on aerobic capacity in athletes. Relevant studies were identified through electronic databases such as PubMed, Scopus, and Google Scholar using keywords related to respiratory muscle training, VO₂max, and athletes. The reviewed studies generally reported improvements in inspiratory muscle strength, reduced respiratory muscle fatigue, and enhanced ventilatory efficiency following RMT interventions. These physiological adaptations may contribute to better exercise tolerance and overall athletic performance. However, evidence regarding direct improvements in VO₂max remains inconsistent across studies. The findings suggest that RMT can be used as a complementary strategy alongside conventional training programs to support aerobic performance. In addition, improved respiratory muscle function may provide benefits in health promotion and rehabilitation by reducing dyspnea and increasing exercise tolerance. Further well-designed studies are needed to clarify the extent of RMT’s contribution to improving VO₂max in athletic populations.
