Abstract

Ants are a group of social insects that belong to the order Hymenoptera and the Family Formicidae. This study aims to determine the type of ants (Formicidae) in the Mangrove Area of Tatengesan Village, Southeast Minahasa. This research occurred in Tatengesan Village, Posumaen District, Southeast Minahasa Regency, North Sulawesi. The research method uses a purposive sampling method with the placement of the paths determined based on considerations taking into account the physical and biological conditions that affect the presence of ants in the field. Observation lines were made in as many as three transects, each with four observation plots. Data was collected using adhesive paper traps (Fly Sheet) and direct capture method (hand collecting) and analyzed using the Shannon-Weiner diversity index, species richness index, and species evenness index. Placement of self-adhesive paper on each transect, including lower tree stratum, highest tide limit, middle tree stratum, and upper tree stratum. Based on the results of the research on the observation transect, there were five genera, namely Anoplolepis with 25 individual ants, Camponotus with 31 individual ants, Crematogaster with 98 individual ants, Oecophylla 2168 ants, and Tetraponera 6 individual ants from 6 species of ants consisting of Anoplolepis gracilipes, Camponotus atriceps, Camponotus sp., Crematogaster scutellaris, Oecophylla smaragdina, and Tetraponera nigra. The highest number of genera obtained was Oecophylla, the highest number of species was Oecophylla smaragdina, and the number of individuals caught was 2168.

Abstract

Chicken meat (Gallus gallus domesticus) plays an important role in society with its role as one of the sources of fulfillment of animal protein in Indonesia. With the high consumption of chicken meat by the public, the hygiene and safety of chicken meat must be ensured so as not to incur losses to the people. This study aimed to determine the bacterial contamination based on the testing of Total Plate Counts, Coliform, Escherichia coli, and Salmonella sp. Meet the requirement of the Indonesian National Standard on chicken meat in the traditional market of Langowan Selatan District. The method used in this research is a descriptive method to analyze and describe the results of the study, the testing using several indicators to directly conclude bacterial contamination. The results of the total plate count bacterial contamination test of the colonies, TPC in sample 1 = 29,1x kol/, sample 2 = 29,4x kol/, sample 3 = 27,7x kol/. MPN of Coliform and Escherichia coli results obtained in samples S1, S2, and S3 are 11x kol/gr. The results of microbact Salmonella sp. In samples S1 are positive, and S2 and S3 are negative. Based on observations, it is suspected that contamination occurs because sellers use equipment that is less sterile and there is no cover or barrier so the chicken meat is in direct contact with the air and customer. It is concluded that based on bacterial testing indicators, chicken meat in the traditional market of Langowan Selatan District has exceeded the limit of SNI 7388 2009 and is contaminated.
