Abstract

Sodium benzoate contains dangerous substances including the chemicals benzene, benzoic acid and sodium hydroxide. As a result of these dangerous contents, it can affect blood components such as erythrocytes, hemoglobin, leukocytes and platelets. The effects caused by food preservatives can be prevented by living a healthy lifestyle and using herbal plants as medicinal therapy. One of them is by using natural ingredients, namely keji shard leaves. This study aims to determine keji beling leaf extract on the number of erythrocytes, hemoglobin, leukocytes and platelets due to food preservatives. The stages in this research include phytochemical screening, observing the number of erythrocytes, hemoglobin, leukocytes and platelets. Data analysis used one way ANOVA and Duncan's test. The results of the study showed that administration of sodium benzoate had an effect on increasing the number of erythrocytes 24.35 ± 0.62, hemoglobin 68.0 ± 2.5, leukocytes 21.80 ± 1.68 and platelets 591.7.8 ± 10.5. Meanwhile, administration of keji beling leaf extract can reduce the number of erythrocytes by 13.00 ± 0.18b, hemoglobin by 26.2 ± 2.2b, leukocytes by 13.00 ± 0.74b and platelets by 353.0 ± 09.4b. The optimal dose of keji beling leaf extract to reduce the number of erythrocytes, hemoglobin, leukocytes and platelets is a dose of 500 mg/kg BW

Abstract

Drinking water is a very important need for the body. Drinking water can be treated from borehole water sources which are not necessarily free from harmful chemical and microbiological substances such as pH and manganese. The aim of this research is to improve the quality of drinking water from Borehole water. The filter media used is treated natural zeolite type TNZ RC. 42, Activated carbon granular cartridge, and 1 and 3 µm Melt Blown Filter Cartridge. The testing parameter is chemical test (pH and Mn) and microbiology test (total coliform). The increment in pH levels from the research data were obtained sample A of 7,01, sample B of 7,08, sample C of 7,05 and sample D of 7,24, while the decrease in Mn levels from the research data were obtained sample A of 0,387 mg/L, sample B of 0,429 mg/L, sample C of 0,442 mg/L and sample D of 0,501 mg/L. In total coliform sample A, B, C and D of 0 CFU/100 mL, whose value may not exceed the maximum allowed standard of PERMENKES RI No.492/MENKES/PER/IV/2010.

Abstract

Animal health is an absolute requirement to produce optimum productivity. One of the problems faced by cattle farmers is endoparasite attacks that can cause cows to become thin, have no appetite, and lower selling prices. This study aims to determine the types of worm and protozoa endoparasites, the degree of infection, the prevalence and intensity of endoparasitic attacks on cow feces that are raised extensively and intensively in Setia Janji District, Asahan Regency. The methods used for the identification of the type of endoparasite are sedimentation and flotation. While the method used for the calculation of eggs / oocysts per gram of feces uses Mc. Master. From 60 fecal samples examined, 12 species of worms were found, namely Paramphistomum sp., Fasciola sp., Dicrocoelium sp., Oesophagostomum sp., Trichostrongylus sp., Capillaria sp., Haemonchus sp., Cooperia sp., Ascaris sp., Bunostomum sp., Trichuris sp., Strongyloides sp., and 2 protozoa namely Buxtonella sp., and Eimeria sp.

Abstract

Daging sebagai asal protein hewani semakin dibutuhkan oleh masyarakat. Gabus (Channa striata) adalah ikan air tawar dengan albumin tinggi. Kualitas fisik dan kimia daging itik Peking (Anas platyrhynchos domestica L.) dipengaruhi oleh pemberian makanan tambahan tepung ikan gabus. Balai Standardisasi dan Pelayanan Jasa Industri Medan serta Laboratorium Inseminasi Buatan menjadi lokasi penelitian ini. Pada penelitian ini digunakan 25 itik peking DOD (Anas platyrhynchos domestica L.). Menggunakan Rancangan Acak Lengkap (RAL), yang memiliki 5 perlakuan dan 6 kali pengulangan. Penelitian ini mengkaji parameter pH, daya ikat air, susut mentah, susut masak, kadar air, kadar lemak, dan kadar protein. Pakan perlakuan termasuk dari P0 (pakan perlakuan tanpa pakan tambahan); P1 (pakan kormesil 980 gram, tepung ikan gabus 20 gram); P2 (pakan kormesil 960 gram, tepung gabus 40 gram); P3 (pakan kormesil 940 gram, tepung ikan gabus 60 gram); dan P4 (pakan kormesil 920 gram, tepung ikan gabus 80 gram). Oneway ANOVA digunakan untuk menganalisis data. Hasil penelitian menyatakan bahwa pemberian makanan tambahan tepung ikan gabus berdampak nyata (P<0,05) terhadap pH daging itik peking 0,026 dengan rata-rata 6,0%; dampak nyata (P<0,005) terhadap daya ikat air 0,001 dengan rata-rata 75,96%; tidak ada dampak nyata (P>0,005) terhadap susut mentah 0,574 dengan rata-rata 4,09%; berdampak nyata (P<0,005) terhadap penyusutan masakan 0,011 dengan rata-rata 19,37%; berdampak nyata (P<0,005) terhadap kadar air 0,003 dengan rata-rata 76,00%; berdampak nyata (P<0,005) terhadap kadar lemak 0,000 dengan rata-rata 5,21%; berdampak nyata (P<0,005) terhadap kadar protein P<0,005 dengan rata-rata 18,97%. Kata Kunci: Kualitas Daging, Lemak, Pakan Tambahan, Protein, Tepung Ikan Gabus
