Abstract

Brotowali mengandung senyawa triterpenoid (saponin) yang bersifat antimakan (antifeedant) karena rasanya yang pahit dan kemampuan dalam menurunkan kerja enzim pencernaan (protease dan amilase). Penelitian ini bertujuan menganalisis kemampuan ekstrak etil asetat isolat khamir endofit pada tanaman Brotowali (Tinospora crispa, L.) berfungsi sebagai inhibitor α-amilase untuk penurunan kadar lemak abdominal, lemak subkutan, dan bobot badan pada tikus. Campuran reaksi uji inhibitor α-amilase dengan ekstrak 1%, 5%, 10% dan acarbose 0,1% sebesar 25 μl, uji kontrol ditambah aquades 25 μl. Enzim sebesar 475 μl dicampurkan dan diinkubasi pada suhu 25°C selama 10 menit. Substrat amilum sebesar 500 μl ditambahkan ke dalam campuran reaksi dan diinkubasi pada suhu 25°C selama 10 menit. Reaksi dihentikan dengan 2 ml DNS. Semua larutan yang telah dicampurkan dipanaskan pada suhu 100°C selama 5 menit dan didinginkan. Larutan yang dihasilkan dengan perubahan warna kemudian diukur absorbansinya menggunakan spektrofotometri pada panjang gelombang 540 nm. Penelitian in vivo menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dengan 3 kali ulangan, yaitu kelompok kontrol, perlakuan acarbose 0,1% dan perlakuan ekstrak isolat khamir endofit DG26 dosis 40 mg, 50 mg, dan 60 mg. Pemberian pakan dan minum secara ad libitum. Hasil uji in vitro ekstrak 1% memiliki kemampuan inhibisi terhadap α-amilase sebesar 10,87%, hampir sama dengan acarbose sebesar 9,52%. Hal ini menunjukkan bahwa isolat terpilih yaitu isolat khamir endofit DG26 memiliki potensi untuk dimanfaatkan sebagai inhibitor α-amilase. Hasil uji in vivo menunjukkan bahwa pemberian ekstrak khamir endofit DG26 berpengaruh signifikan pada penurunan bobot lemak abdominal dan lemak subkutan (p<0,05). Bobot badan setelah aklimatisasi terjadi peningkatan yang menunjukkan bahwa tikus dalam keadaan sehat dan terjadi penurunan diakhir perlakuan. Berdasarkan penelitian dapat disimpulkan bahwa pemberian ekstrak isolat khamir endofit DG26 pada dosis 60 mg mampu menurunkan bobot lemak abdominal, lemak subkutan, dan menyebabkan terjadinya perbedaan penurunan bobot badan pada tikus (Rattus norvegicus).

Abstract

Broilers (Gallus domesticus) are prone to stress and immune suppression due to inadequate environmental conditions and feed quality. Spirulina, known for its antioxidant and immunostimulant properties, and liquid nano chitosan, which has antibacterial activity, are considered promising feed additives for broiler health. This study aimed to evaluate the effects of Spirulina flour, liquid nano chitosan, and their interaction on broiler leukocyte profiles. A factorial completely randomized design was used, with six treatment groups and four replications. Treatments included a control and diets supplemented with 0; 3; or 6% Spirulina powder, combined with 0 or 5% liquid nanochitosan. The treatments were applied for 26 days. Leukocyte observations were performed using Giemsa-stained blood smears at 400× magnification. Data were analyzed using Two-Way ANOVA (α= 0.05) and the Friedman Test. Results showed normal leukocyte morphology. Spirulina supplementation had no significant effect (P >0.05) on leukocyte, heterophil, or lymphocyte counts. In contrast, 5% liquid nano chitosan significantly affected (P <0.05) leukocyte and lymphocyte numbers. No interaction between the two additives was observed. In conclusion, Spirulina (3–6%) showed potential as a feed additive, while 5% liquid nano chitosan reduced leukocyte and lymphocyte counts. These natural additives may support broiler health without altering leukocyte profiles.

Abstract

Background: Diphtheria remains a persistent public health issue, especially in low- and middle-income countries (LMICs), where vaccination coverage is often inadequate. Recent outbreaks, such as those in the 1990s, highlight the ongoing threat posed by this vaccine-preventable disease. The World Health Organization (WHO) provides data for monitoring the global trends in diphtheria cases, helping countries remain vigilant against its resurgence. Objective: This study aims to analyze the trend of diphtheria cases and incidence rates in 10 countries with the highest disease burden as a public health challenge in Low- and Middle-Income Countries (LMIC), with a focus on the impact of vaccination coverage. Methods: Longitudinal study was utilized in this research. G-power was performed to calculate the sample size. In accordance with the goal year that was being investigated, the research ranked the nations that were chosen into the top ten countries that had the largest number of cases of diphtheria. Our analysis was based on secondary data obtained from the WHO and included the years 2017 through 2021. In order to assess the distribution of healthcare access and vaccine coverage, we conducted a descriptive analysis of all of the data. This served the purpose of identifying significant public health concerns that contribute to diphtheria epidemics. We used the Stata 16 application to perform analysis on all of the data. Results: The majority of diphtheria cases occur in African and Asian countries, especially in areas with lower DTP-3 vaccination coverage. Yemen, Ethiopia, and Nigeria have high diphtheria rates due to disparities in access to health services and immunization programs. Countries with higher vaccination rates, such as India and Indonesia, report lower rates despite having high numbers of cases. This suggests that strong immunization programs are essential to control the disease. Conclusion: Diphtheria continues to be a significant public health challenge in LMICs, exacerbated by geographic and socioeconomic disparities in vaccination coverage. Global cooperation, including support from high-income countries, is essential to strengthen immunization programs and prevent future outbreaks. Diphtheria should be recognized as a global health threat, requiring comprehensive and coordinated efforts to achieve eradication. Keywords: Diphtheria; incidence rate; reported cases; vaccinated

Abstract

Itik peking merupakan itik pedaging yang banyak dibudidayakan di Indonesia. Pemberian pakan dalam pemeliharaan itik di peternakan itik rakyat masih banyak yang belum memenuhi standar kebutuhan nutrien itik. Suplemen pakan dapat menjadi upaya pemenuhan nutrien pakan pada itik. Tepung spirulina merupakan bahan pakan yang dapat dimanfaatkan sebagai suplemen. Penelitian ini bertujuan menganalisis tepung spirulina sebagai suplemen pakan terhadap profil eritrogram itik peking. Itik dibagi menjadi 5 kelompok perlakuan, yaitu P0 (kontrol negatif), P1 (penambahan 2,5% tepung spirulina), P2 (penambahan 5% tepung spirulina), P3 (penambahan 7,5% tepung spirulina), dan P4 (penambahan 10% tepung spirulina). Data profil eritrogram dianalisis menggunakan uji One-Way Analysis of Variance (ANOVA) pada taraf kepercayaan 95%. Hasil analisis data pada parameter jumlah eritrosit, hemoglobin, hematokrit, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), dan mean corpuscular haemoglobin concentration (MCHC) menunjukkan berbeda tidak nyata (P>0,05). Nilai eritrosit, hemoglobin, hematokrit, MCV, MCH, dan MCHC pada kontrol, secara berurutan adalah 2,33 juta/mL; 12,10 g/dL; 37,94%; 162,54 fL; 52,01 pg; dan 32,01 g/dL, sedangkan pada perlakuan P1, P2, P3, dan P4 nilai dari kelima variabel tersebut, secara berurutan berkisar antara 2,36-2,56 juta/mL; 11,94-12,64 g/dL; 38,40-43,60%; 162,11-171,35 fL; 49,44-52,72 pg; dan 29,29-31,47 g/dL. Kesimpulan penelitian ini adalah tepung spirulina sebagai suplemen pakan tidak meningkatkan jumlah eritrosit, hemoglobin, hematokrit, MCV, MCH, dan MCHC pada itik peking.  Peking ducks are a type of meat duck widely farmed in Indonesia. In duck farming, especially in smallholder farms, the feed provided often does not meet the nutritional standards required for optimal growth. Feed supplements can be an effective way to address nutrient deficiencies in duck diets. Spirulina flour is a feed ingredient that can be used as a supplement. This study aims to analyze the effects of spirulina flour as a feed supplement on the erythrogram profile of Peking ducks. The ducks were divided into five treatment groups: P0 (negative control), P1 (2.5% spirulina flour), P2 (5% spirulina flour), P3 (7.5% spirulina flour), and P4 (10% spirulina flour). Erythrogram profile data were analyzed using a One-Way Analysis of Variance (ANOVA) at a 95% confidence level. The results showed no significant differences (P>0.05) in the erythrocyte count, hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), and mean corpuscular haemoglobin concentration MCHC variables. The values of erythrocytes, hemoglobin, hematocrit, MCV, MCH, and MCHC in the control group were 2.33 million/μL; 12.10 g/dL; 37.94%; 162.54 fL; 52.01 pg; and 32.01 g/dL, respectively. Meanwhile, in the treatment groups P1, P2, P3, and P4, the values of these six variables ranged sequentially from 2.36–2.56 million/μL; 11.94–12.64 g/dL; 38.40–43.60%; 162.11–171.35 fL; 49.44–52.72 pg; and 29.29–31.47 g/dL.The conclusion of this study is that spirulina flour as a feed supplement does not improve erythrocyte count, hemoglobin, hematocrit, MCV, MCH, or MCHC in Peking ducks.

Abstract

Jantung dan aorta merupakan organ penting dalam sistem sirkulasi. Penelitian ini dirancang dengan tujuan menganalisis histomorfometri jantung dan aorta itik hibrida yang diberi imbuhan pakan tepung daun kelor. Itik yang digunakan adalah itik hibrida jantan berjumlah tiga puluh dua ekor dibagi ke dalam empat jenis perlakuan, yaitu K0: Pakan standar (pakan tanpa imbuhan tepung daun kelor), K1: pakan dengan imbuhan tepung daun kelor 2,5%, K2: pakan dengan imbuhan tepung daun kelor 5%, dan K3: pakan dengan imbuhan tepung daun kelor 7,5%. Masing-masing perlakuan terdiri atas delapan ekor itik. Imbuhan pakan diberikan selama enam minggu. Histomorfometri jantung dan aorta diperoleh dengan pembuatan preparat histologi metode parafin dan pewarnaan hematoksilin eosin. Data penelitian dianalisis menggunakan analisis sidik ragam dengan software SPSS versi 26. Hasil penelitian memperlihatkan imbuhan pakan tepung daun kelor tidak berpengaruh (P>0,05) terhadap bobot jantung, tebal epikardium, miokardium, endokardium, tebal tunika adventisia, tunika media, dan tunika intima. Kesimpulan dari penelitian bahwa pemberian imbuhan tepung daun kelor konsentrasi 2,5%, 5%, dan 7,5% tidak mengubah struktur histologi jantung maupun aorta sehingga aman dipergunakan sebagai aditif pakan itik. The heart and aorta are important organs in the circulatory system. This study was designed to analyze the histomorphometry of the heart and aorta of hybrid ducks given feed supplemented with moringa leaf powder. The research used a Completely Randomized Design (CRD) with four types of treatments, i.e., K0: standard feed (without the addition of moringa leaf meal), K1: feed with the addition of 2.5% moringa leaf meal, K2: feed with the addition of 5% moringa leaf meal, and K3: feed with the addition of 7.5% moringa leaf meal. Data were analyzed using analysis of variance. The results indicated that the addition of moringa leaf meal to the feed had no effect (P > 0.05) on heart weight, epicardium thickness, myocardium, endocardium, adventitia tunica, media tunica, and intima tunica. The conclusion of the study is that the addition of moringa leaf powder at concentrations of 2.5%, 5%, and 7.5% did not alter the histological structure of the heart or aorta, making it applicable as a duck feed additive. Additionally, the findings suggest that moringa leaf powder is a safe option for enhancing the nutritional profile of duck feed without compromising cardiovascular health.
