Abstract

This study was conducted in the intertidal zone in the waters of Bagan Siapi-api Rokan Hilir Regency in May-June 2018. This study aims to examine morphometrics and growth patterns in blood clams (Anadara granosa) in Bagan Siapi-api waters. A total of 100 samples (23.89-50.52 mm shell length and 3.85-18.16 grams total weight) were analyzed. From the results of observations it was found that the number of male and female ribs was 8-20, and there were 3 differences in morphometric characteristics between male and female, namely male blood clams longer than females, while female blood shells were wider and thicker than males. Furthermore, the growth pattern of A. granosa was negative allometric, with male b values 1.46 and females 0.74.

Abstract

The Sail River is the position in the center of Pekanbaru City and is affected because of the tides. Urban pollution is a significant giver to the Sail River of water quality degradation. The study was conducted between June and August to assess estimation pollution load Sail River and pollution levels using the Pollution Index method. Water quality parameters measured are physical (temperature, TSS) and chemical (pH, dissolved oxygen, BOD, COD, Pb, oil and grease, nitrate, as well as phosphate). The results showed that the Sail River was classified as lightly polluted at high tide and low tide. The pollution index value at high tide is higher with a range of 3.65-3.92 than at low tide (2.93-3.39). TSS is the highest pollution load of the Sail River that a value of 1079.83 mg/second at high tide and 1075.29 mg/second at low tide. The lowest pollution load is oil and grease at low tide (0.47 mg/second). Thus, it is necessary to control the level of water pollution in the Sail River.

Abstract

Chlorella Jelly Genki is a kind of health drink to increase the immune system or the level of people's immunity from various diseases including Covid-19 which is packaged in plastic cups that can be sold commercially at a price of Rp. 10,000/cup. Within 10 months from September 2020 to July 2021, 5321 cups have been sold with consumers from various circles including academics from universities such as students and lecturers at the Riau University and Riau Islamic University, Government Employees, Members of the Riau Regional House of Representatives, and the congregation of mosques such as the Rodatul Jannah mosque, Pekanbaru and the general public. To further increase the marketing reach of Chlorella Jelly Genki to the wider community, various strategies or efforts are needed, including developing websites using digital technology and marketing promotions through community service activities by involving student groups as the driving force through integrated Community Service Activities. Abdimas in 2021. This Community Service activity has been carried out from May 2021 to early August 2021, the report of which is presented in this paper. The first way is by developing a digital technology website and marketing promotion through social media in the form of a home page, which can be done under the name: http://genkinusantara.com/. While the second way is to directly invite the target community group to come to the Algae Research Center. The results of this community service show that of the 244 people who were invited, 115 people or 47.1% of them expressed their willingness to become a distributor or selling agent of Chlorella Jelly Genki. While 26 people (10.7%) were still unsure or still needed further consideration to become a distributor or sales agent, 94 people (38.5%) firmly stated that they were not or not yet willing and 94 people (38.5%) ) people (3.7%) did not provide an answer.

Abstract

Pangasianodon hypophthalmus is a freshwater fish that can grow well in dark condition. In no light condition, fishes are more responsive to feed provided. However, phytoplankton may not grow well, and as a consequence the water quality was poor and it negatively effects the fish health in general. The combination of biofloc and photoperiod manipulation systems is expected to improve the water quality as well as the fish health. To understand health status of the fish in general, the histological structure gill, kidney and liver was investigated. Sample were fixed in 5% formalin, paraffin processed and Haematoxylin Eosin stained. There were 2 factor, 3 treatment applied, namely natural (control), 18G (18 hours dark), 24G (24 hours dark) and 3 repetition. Parameter measured were survival rate and histological structure of gill, kidney, intestine and liver. Results shown that there are not difference of histological structure of the organs of fish reared under biofloc and manipulated photoperiod systems. There were light abnormalities in the gill, such as hyperplasia, hypertrophy, oedema and necrosis. There is no negative effect of biofloc system and photoperiod manipulation in structure of fish organ as there is only light abnormalities that can be cured when the water quality is good.
