Abstract

Sweet potato agribusiness has promising economic prospects for both producers and the country. For producers, it serves as a main source of income in rural areas, while for the country, it contributes to foreign exchange earnings due to the high demand in the international market. This study aims to analyze the feasibility of sweet potato farming based on the benefit-cost ratio (B/C) indicator. The research was conducted in Sei Beras Sekata Village, Sunggal District, Deli Serdang Regency. The population consisted of farmers cultivating sweet potatoes on leased land, with a sample size of 31 respondents selected using the census method. The results showed that the B/C ratio was 5.61, meaning that for every IDR 1 spent on farming costs, farmers received a benefit of IDR 4.61 per hectare. The magnitude of the B/C ratio is influenced by the level of income and farming costs. The study found that the income obtained was IDR 59,935,618/ha, while the total costs amounted to IDR 10,696,168/ha. Income was influenced by the quantity and price of production, while costs were affected by the quantity and price of production factors used in sweet potato agribusiness.

Abstract

Pork is a source of animal protein and the main food ingredient which is always provided in every religious, customary and social activity in East Nusa Tenggara and Manggarai in particular. In Manggarai, pork is traded in many traditional and modern markets, one of which is the Ruteng market. Pork in the Ruteng market is sold in an open place with a location that is not guaranteed for cleanliness so that it can cause bacteria to thrive. One of the microorganisms that can contaminate pork is Escherichia coli. This study aims to identify E. coli contamination in fresh pork sold in the Ruteng market. This research was analyzed with a quantitative descriptive approach. Identification was carried out on 6 samples of pork through planting on EMBA media as an E. coli confirmation test and IMViC test which consisted of SIM test, MRVP test and SCA test. The identification results showed that the six pork samples were positive for Escherichia coli. These results confirm that there is contamination of E. coli bacteria in fresh pork sold at Ruteng Market, East Nusa Tenggara.
