This research purpose to know of wide diversity of the yard in the Village of Tambusai Timur District of Tambusai Rokan Hulu Regency Province of Riau. This research have done on February until April 2018 that used direct observation (server inventarisasi). The plant that can be identify the researcher describ them with character of morfologyzal the source of reference the result of this research. Get the poin and indeksof wide diversity of the yard the telatively high on stasiun one (4,65), stasiun two (4,90) and stasiun three (3,72). That get 53 family, 96 genus and 107 species. The plant have habitus tree, shrub shaped or herbs that in use for ornamental plant, fruit and, food and medicine. All the species can get from the family Apocynaceae, Araceae, Euphorbiaceae, Myrtaceae, Palmae, Rutaceae and Zingeberaceae.

This service activity aims to increase students' knowledge about photosynthetic bacteria as plant fertilizers, so that they can increase student awareness to increase knowledge and it is hoped that knowledge can be used as capital for entrepreneurship. This activity also provides knowledge about photosynthetic bacteria starting from the understanding, characteristics to the working mechanism of bacteria. Methods and techniques of socialization consist of: planning, action and reflection. In planning, the preparation and dissemination of activities were carried out, at the action stage, the service was carried out starting with the exposure of photosynthetic bacteria, the working mechanism of bacteria and their benefits as plant fertilizers, and a question and answer session was held. The next stage is reflection, which is done by analyzing the participants' responses to the activities that have been carried out. In this service activity, the students were enthusiastic.

The purpose of this research was to know the influence of the addition of Ginger flour in the feed to the value of the levels of lipid and protein Broiler meat. These researches were conducted that used Soxhlet method to tested the lipid quality and Kjeldahl method to tested the protein. The sample were used Broiler aged 1 weeks up to 2 weeks, after 2 weeks old chicken was divided into 4 treatment groups of 6 each control group (P0) without treatment, P1 with addition of ginger flour in feed 2.5%, P2 in the addition of ginger flour in the diet of 5%, P3 with the addition of ginger flour in the feed as much as 7.5%. After 42 days old, Broiler conducted sampling of meat in the treatment for the examination of the levels of lipid and protein. The Data obtained are then analyzing used a One-way Anova. The result of these researches is in the range of lipid quality: P0 (8,33%), P1 (6,33%), P2 (5,25%), P3 (5,08%) After analyzed have done it shown there were differences that significance (p>0,05). Result of checked of protein quality: P0 (5,59%), P1 (5,32%), P2 (5,36%), P3 (5,45%) After analyzed were done there is no significance difference (p>0,05). The higher the percentage of ginger flour, the lower the fat content of broiler chicken.

The objective of present study was to identify bioactivity of antibacterial Indonesian Seagrass Thalassia hemprichii dan Enhalus acoroides from Karang Tirta Beach, Padang City, West Sumatera. This is a preliminary research for a new alternative antibiotic from Seagrass in Indonesia. In this study the seagrass was examined by a maceration process and using the rotary evaporator to obtain viscous extract. The material for the bioactivity testing was performed upon several intended bacteria such as Escherichia coli, Stapillococcus aureus, and Bacillus subtilis. The bioactivity testing was performed by using the method of resazurin and MIC (Minimum Inhibitory Concentration), which is determined by looking at well blue-colored at the smallest concentration. The result revealed that the best antibacterial bioactivity of Thalassia hemprichii extract was a total of 62.50 μg/mL N-hexane solvent against Escherichia coli and Stapillococcus aureus bacteria. While the best antibacterial bioactivity of Enhalus acoroides extract is 15.62 μg/mL of N-hexane solvent against Stapillococcus aureus.
