Photobioreactor (PBR) have been one of the most popular system that used for multiplying microalgal biomass. Many researches have been conducted to develop photobioreactor that suit the most with prominent microalgae strains. Carbon dioxide supply is one of many sectors that play an important role for growing microalgae. Carbon dioxide are used by the microalgal cells to produce many chemical compounds that support growth. In many cases, carbon dioxide must be solved into growth media to be utilized by the cells. This research focused on analyzing the effect of carbon dioxide solubility increasement caused by variation of baffle in airlift photobioreactor (APBR) to growth rate of Synechococcus HS-9 biomass. Twenty-one day of experiment resulting that there are growth rate differences occurs. The highest growth rate occurs in APBR-A, APBR-B, and control PBR are 0.515, 0.463, and 0.738 respectively. Despite of the maximum growth rate occurred, there are fluctuation of growth rate happen during experiment. Carbon dioxide solubility test then conducted to see effect of baffle variation. The best carbon dioxide solubility occurred in APBR-B with 23 mg/L, then followed by APBR-A with 22 mg/L, and control PBR with 20 mg/L after 24 hours of treatment. Further analysis resulting that there is no strong correlation between carbon dioxide solubility increasement to growth rate of Synechococcus HS-9 biomass. This occurred due degression of acidity value (pH) caused by excess of carbonic acid formed by carbon dioxides who diluted into growth media.

Carbon dioxide is gas produced by industrial pollution and motor vehicle exhaust emissions. The air is declared clean and healthy for human activities if the CO level does not exceed 15 ppm. Industrial pollution or motor vehicle pollution does not only pollute the outdoor air, but it is very likely to pollute the indoor air. For this reason, a system that is able to monitor and control CO levels in the room has been designed so that it is safe for users while doing this activities. The research stage is carried out by making a series of sensors to detect CO gas and then the sensor circuit is connected to the Arduino UNO microcontroller as an interface with a PC. The program used is LabVIEW programming as a neural programming for displaying Virtual Instruments as display media. The output system is an air purifier system that cleans the indoor air when the CO level is more than 15 ppm. Based on the results of trials and analyzes, the response of the sensor system is able to detect changes in CO gas within 7 seconds. The average monitoring of CO levels result when observed 30 times was 11.47 ppm. The air purifier response time is able to restore indoor CO levels to the maximum threshold of 15 ppm in the fastest time of 3 minutes and 22 seconds.

“…Menurut national oceanic and atmospheric administration (NOAA) bahwa CO2 sangat efektif dalam menjebak panas dengan waktu tinggal paling lama di atmosfer sehingga menyebabkan peningkatan suhu secara global. Karbondioksida sendiri merupakan salah satu komponen GRK utama di atmosfer yang berperan dalam siklus biogeokimia pada perairan (Prasetyawan et al, 2017). Emisi CO2 di atmosfer dapat diminimalisir dengan cara memanfaatkan kemampuan wilayah pesisir sebagai penyerap karbon alami melalui fitoplankton dan tumbuhan air seperti lamun (Indriani et al, 2017).…”

Peningkatan emisi Gas Rumah Kaca (GRK) terutama karbondioksida (CO2) menyebabkan pemanasan global. Oleh karena itu diperlukan mitigasi emisi CO2 dengan memanfaatkan potensi lamun sebagai penyimpan karbon dalam bentuk biomassa. Tujuan penelitian ini untuk mengetahui kemampuan lamun jaringan atas dan jaringan bawah dalam menyimpan karbon di perairan Pantai Pokemon pada Agustus 2020. Metode penelitian yang digunakan yaitu metode survei dan deskriptif eksploratif. Sampel diambil dari 3 stasiun pengamatan dengan line dan kuadrant transect menggunakan metode purposive sampling. Pengukuran parameter kualitas perairan dilakukan secara insitu. Analisis simpanan karbon lamun diukur menggunakan metode pengabuan atau loss on ignition (LOI). Hasil penelitian menunjukkan terdapat 4 jenis lamun yaitu Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, dan Halophila ovalis dengan jenis T. hemprichii yang mendominasi. Total kerapatan sebesar 295,62 ind/m2 dan total penutupan yaitu 21,29%. Biomassa secara keseluruhan sebesar 74,42 gbk/m2 dengan biomassa jaringan atas sebesar 35,80 gbk/m2 dan jaringan bawah sebesar 38,62 gbk/m2. Simpanan karbon sebesar 0,23 ton C/ha dengan jaringan atas sebesar 0,10 ton C/ha dan jaringan bawah 0,13 ton C/ha. Total stok karbon mencapai 1,13 ton C dalam luasan padang lamun sebesar 4,903 ha dengan stok karbon jaringan atas bernilai 0,51 ton C dan jaringan bawah sebesar 0,62 ton C. Secara umum lamun jaringan bawah di Pantai Pokemon lebih besar menyimpan karbon.
