Abstract

DNA isolation and gene amplification of algae are significantly influenced by various factors such as characteristics and components of the algae cell wall. Therefore techniques and methods of DNA isolation in certain algae, sometimes only succeed in one particular species and can not be applied to another algae species. Based on that issue, this study was conducted with the aims to determine the succeed of DNA isolation and amplify the rbcL gene as a target gene for identification. Algae DNA was isolated by using innuPrep Plant DNA commercial kit, and the second one with a modified conventional Cetyl Trimetyl Ammonium Bromide (CTAB) method,  for the amplification process was using rbcL gene (ribulose-1,5-bisphosphate carboxylase / oxygenase large subunit) with two pairs of primers : rbcL 7F-753R and rbcL 577F-rbcSR. The results showed that the DNA of Gracilaria sp was succeed isolated by using CTAB method and it was denoted by the presence of DNA bands in agarose gel. Meanwhile DNA amplification for Gracilaria sp., and Sargassum sp., were succeed amplified with the appearance of DNA bands. But in algae Caulerpa sp., was only succeed on 1 pair of primary rbcL 7F and 7.Keywords : DNA, gene rbcL, algae Caulerpa sp., Sargassum sp., Gracilaria sp;AbstrakIsolasi DNA dan amplifikasi gen pada alga sangat dipengaruhi oleh beberapa faktor seperti karakter dan komponen pada dinding sel alga. Oleh karena itu proses isolasi DNA terkadang bisa berhasil pada satu jenis alga, namun tidak berhasil pada jenis alga lainnya. Oleh karena alasan tersebut, maka penelitian ini dilakukan untuk menentukan keberhasilan Isolasi DNA dan mengamplifikasi gen rbcL sebagai gen target identifikasi. Penelitian ini dilakukan dengan tahapan awal Isolasi DNA yang menggunakan kit komersil innuPrep Plant DNA Kit, dan metode konvensional Cetyl Trimetyl Ammonium Bromide (CTAB) yang telah dimodifikasi. Sedangkan untuk proses amplifikasi, menggunakan gen rbcL (ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit) digunakan dua pasang primer yaitu rbcL 7F-753R dan rbcL 577F-rbcSR. Hasil isolasi DNA dari alga Gracilaria sp berhasil diisolasi menggunakan metode CTAB yang ditandai dengan adanya pita DNA pada gel agarose. Amplifikasi DNA pada alga Gracilaria sp., dan Sargassum sp., berhasil diamplifikasi dengan munculnya pita DNA. Namun pada alga Caulerpa sp. hanya berhasil pada 1 pasang primer rbcL 7F dan753R.Kata kunci : DNA, gen rbcL, alga Caulerpa sp., Sargassum sp., Gracilaria sp.

Abstract

Sea Surface Temperature (SST) is the temperature of the water measured at sea level. SST is a crucial marine parameter that influences the weather and climate in Indonesia. The value of sea surface temperature will be very closely related to factors such as the depth of measurement from sea level, the intensity of sunlight received, season, weather, water depth, air circulation, and cloud cover. This study aims to design a prototype tool to measure wind speed and sea surface temperature parameters. The components used are the DS18B20 sensor, JL-FS2 sensor, Arduino Mega 2560, and the SIM900a GSM Module. The system is displayed in real-time via the Thingspeak website, accessed via a PC or smartphone. The DS18B20 sensor, as a sea surface temperature sensor, can measure these parameters by looking at the trend of changing day and night temperatures. The JL-FS2, as a wind speed sensor, has been able to measure wind speed parameters during field tests at FADs.
