Abstract

The research on bacterial testing on boiled water of boiled mackerel (Rastelliger sp) has been conducted. The study applied treatment of boiled water that is not replaced and is used continuously in several stages. This study aims to determine the effect of boiled water on the quality of fish production, and determine its effect on meat tectrus, gill color, and aromas. The study was conducted with a descriptive qualitative method. Boiled mackerel quality is measured using the total plate count method, which is to count the number of bacterial colonies in the water before boiling and after boiling.

Abstract

Research on Types of Anura in Deleng Ketaruman, Bukum Village, Subdistrict Sibolangit, Deli Serdang Regency, North Sumatera Province was conducted in February 2018. This study aims to obtain and document the types of Anura, and environmental parameters found Anura in Deleng Ketaruman, Bukum Village, Subdistrict Sibolangit, Deli Serdang Regency, North Sumatera Utara Province. The method used in this research is Visual Encounter Survey. The equipment used in this research were headlamp, background black, battery, camera, temperature and temperature gauge, plastic, frog capture net, amphibious identification book. Observation of the types of Anura was done during night. Anuras were observed only along the tracking path. The results showed that 9 species consisted of 6 families found along the tracking tracks one species of Bufonidae family (Phrynoidis juxtaspera), three species of Dicroglossidae family (Fejervarya cancrivora, F. limnocharis, Limnonectes blythii), one species of Megophrydae family (Megophrys paralella), one species of Microhylidae family (Microhyla superciliaris), two species Ranidae family (Hylarana chalconota, H. erythraea), and one species of Rhacophoridae family (Polypedates leucomystax). The ambient temperature of the Anura species ranges from 22ºC-24ºC to grassland habitats, puddles, litter and ponds.

Abstract

Bryophyte is a non-vascular plant, consisting of three classes: mosses, hornworts, and liverworts. The body forms have a thallus, and some have a leaf-like organ. The class division of the Bryophyte division is base on anatomical and morphological traits, such as meristem tissues, stomata, and vascular tissues. M Bryophyte has no vascular tissue, but it has a capillary that has functions like xylem and commonly refers to as hydroid. Mosses and hornworts have stomata on the sporophyte part, while in the liverworts, stomata are not found. Hornworts have a basal meristem that has an unpredictable cleavage. Meristem on the mosses only divides up the formation of sporangial. In the liverworts, the apical meristem does not see. Members of the hornworts consider the most advanced because the meristematic phase is more prolonged, so that it is closer to the characteristics of Tracheophyta group.
