Get PDFCandipuro District is an agricultural and plantation area, apart from that the people also raise beef cattle. Beef cattle are used as a source of meat and as a source of fertilizer for agriculture in the area. There are still some farmers in Candipuro District who raise beef cattle using the traditional method, where the cattle are still kept behind the farmer's house and are given forage in the form of grass. Providing forage in the form of grass can have an impact on livestock health, especially on exposure to gastrointestinal parasites. Gastrointestinal parasite infections are a common problem in cases of gastroenteritis in livestock throughout the world. This can have quite a broad impact, especially on the health of the veterinary community and the health of the livestock itself throughout the world, especially in developing countries. This research was carried out using sample testing using the sedimentation method and also McMaster. Data obtained from the results of testing 193 fecal samples in 14 villages in Candipuro District using the floating and EPG methods, the results obtained are as in table 1. The incidence rate of Trematode parasite infection in Candipuro District is 46.56%. Of the 14 villages, there was a 0% incidence rate of trematode worm cases in Banyumas Village.

Pengaruh Variasi Suhu dan Durasi Pengepresan pada Kualitas Lemak Kakao
Get PDFThis research aims to explore the impact of temperature and duration of cocoa pressing on the properties of the cocoa butter produced, as well as the organoleptic preferences of the panelists. The pressing process uses a hydraulic press method for cocoa paste. This research design was carried out using two factors, namely pressing temperature with three levels: 50°C, 70°C, and 90°C, and pressing duration with three levels: 30, 40, and 50 minutes. The cocoa butter produced was analyzed for yield, free fatty acid content, water content, saponification value, iodine value, peroxide value, and antioxidant activity. The results showed that pressing temperature significantly influenced yield, water content, free fatty acid content, saponification value, iodine value, peroxide value, and antioxidant activity. Meanwhile, the duration of pressing only affects the yield, water content, saponification value, iodine value, and peroxide value. The cocoa butter produced can meet SNI standards. It has high antioxidant activity, which is obtained under operating conditions at a temperature of 50°C for 30 minutes, even though it produces the lowest yield. This research shows that lower pressing temperatures and duration can produce good quality cocoa butter, which panelists accept without changing the aroma, appearance, and original composition, even though the resulting yield is lower.This research aims to explore the impact of temperature and duration of cocoa pressing on the properties of the cocoa butter produced, as well as the organoleptic preferences of the panelists.
