Wastewater has been giving a high contribution to the quality of water bodies. Tofu wastewater is one of the contributors since it might contain high organic loading. Microalgae is one of the promising solutions to improve wastewater treatment, especially organic wastewater. However, every microalga has its specific properties and it will affect the quality of treated wastewater. This study aims to compare Chlorella vulgaris and Spirulina platensis in an oxidation ditch algae reactor (ODAR) for treating tofu wastewater. The ODAR system was set up under ratio wastewater and microalgae 1:1, the sample was taken every day for 7 days of observation. The sample was analyzed for BOD, DO, and Chlorophyll-a. The results showed that Spirulina platensis has a higher performance in removing organic pollutants than Chlorella vulgaris, which is shown 60% BOD removal, higher DO concentration (5-8 mg/L), and 2,67 mg/L of Chlorophyll-a. Performance of Spirulina plantesis in treating organic wastewater was indicated as a fast-growing microalga than Chlorella vulgaris.

“…Struktur klorofil a dan b berbeda pada letak dan jumlah H dan O. Klorofil a (C55H72O5N4Mg), dan klorofil b (C55H70O6N4Mg), klorofil bertindak sebagai pengabsorbsi energi dari matahari sehingga berubah menjadi molekul berenergi tinggi (Ai dan Banyo., 2011). Gambar 4. merupakan struktur dari klorofil a dan b. Berdasarkan hasil penelitian menunjukkan bahwa pigmen karotenoid yang merupakan pigmen aksesoris, ditemukan dalam jumlah yang banyak (2.923,70 µg/mL) diikuti dengan klorofil b (368,69 µg/mL) dan klorofil a (226,85 µg/mL).…”

ABSTRAK Ekosistem lamun merupakan salah satu ekosistem di laut dangkal yang mempunyai peranan penting dalam kehidupan biota laut dan merupakan salah satu ekosistem bahari yang paling produktif, sehingga mampu mendukung potensi sumber daya yang tinggi pula. Fungsi ekologis ekosistem lamun adalah sebagai produsen, pendaur unsur hara, penstabil substrat, penangkap sedimen, habitat dan makanan serta tempat berlindung organisme laut lainnya. Tujuan dari penelitian ini adalah, untuk mengidentifikasi pigmen dan mengetahui kandungan pigmen yang terdeteksi pada lamun Enhalus acoroides (Linnaeus f.) di Perairan Pantai Amadoke Desa Akle Kecamatan Semau Selatan Kabupaten Kupang. Metode yang digunakan dalam penelitian ini adalah metode Survei, Kromotografi Lapis Tipis, dan metode Spektrofotometer. Lamun ini mengandung pigmen terlihat pada hasil analisis spektrofotometer pada ekstrak pigmen total lamun dan pemisahan pigmen lewat uji Kromotografi Lapis Tipis (KLT). Dalam proses ekstraksi digunakan pelarut aseton untuk penggerusan dan perendaman. Dan pada uji spektrofotometer untuk kandungan klorofil a menggunakan panjang gelombang 645 nm dengan pigmen total 226,85 µg/mL, klorofil b 664 nm dengan pigmen total 368,69 µg/mL dan karotenoid 470 nm dengan pigmen total. 2.923,70 µg/mL. Pada pengujian pigmen lewat KLT terdapat sembilan noda yaitu, klorofil a dengan nilai Rf (0,78, 0,84 dan 0,08) klorofil b dengan nilai Rf (0,04), klorofil c dengan nilai Rf (0,12), feofitin dengan nilai Rf (0,22 dan 0,88), fukosantin dengan nilai Rf (0,48) dan karotenoid dengan nilai Rf (1,00). Kata kunci : E. acoroides (Linnaeus f.), pigmen, klorofil dan KLT ABSTRACT Seagress ecosystem is one of the shallow marine ecosystem that has an important role in the life of marine and is one of the most productive marine ecosystem, so that it can support the high potential of high resources as well. The ecological function of seagress ecosystem is as a producer, nutrient recycler, substrat stabilizer, sedimen capture, food and shelter of other organisme. The purpose of the research was to identifi the pigment and determine the pigment content in Enhalus acoroides (Linnaeus f.) seagress in Amadoke waters beach Akle of village, South Semau.The research use survey method, thin layer chromotographic and spectrophotometer methods. This seagress contains pigment, seen in the result of spectrophotometric analysis in total seagress extract and pigment separation through thin layer chromotography test. In the pisment used acetone for steaming and soaking. The spectrophotometric test for the content of chrolophyll a (λ 645 nm), chrolophyll b (λ 664 nm) and carotenoid (λ 470 nm), respectivelly are 226,85 µg/mL, 368,69 µg/mL and 2923,70 µg/mL. Nine pigments found based on the Rf valuef of TLC analisis are chrolophyll a (Rf 0,78, 0,84, 0,08), chrolophyll b (Rf 0,04), chrolophyll c (Rf 0,12), feofitin (Rf 0,22 dan 0,88) and carotenoid (Rf 1,00)

“…Tanaman tingkat tinggi mempunyai dua macam klorofil, yaitu klorofil a dan b. Klorofil a berperan langsung dalam reaksi perubahan energi radiasi matahari menjadi energi kimia, menyerap dan mengangkut energi ke pusat reaksi molekul. Sedangkan klorofil b berfungsi menyerap energi radiasi matahari yang selanjutnya diteruskan ke klorofil a (Ai & Banyo, 2011;Ai, 2012).…”

<em>Morphological characterization of superior Robusta coffee plants has been widely studied, but for the anatomical and physiological character is still relatively limited. Result of this characterization is important as a basic information in order to create the new superior varieties. The purpose of this study was to investigate the morphological, anatomical, and physiological characteristics of seven clones of Robusta coffee (SA 203, BP 534, BP 42, BP 409, BP 939, BP 308 and BP 436). The experiment was conducted at Pakuwon Experimental Station and Integrated Laboratory of Indonesian Industrial and Beverage Crops Research Institute, Sukabumi, West Java, from October to November 2019. The Completely Randomized Design with 7 Robusta coffee clones as treatments and three replications was used in this study. The variable observed were morphological (leaf area), anatomical (stomata shape and density) and physiological characters (chlorophyll a, chlorophyll b and total chlorophyll). The results showed that the leaf area of the first and third leaves of seven clones of Robusta coffee were relatively uniform. The stomata shape of Robusta coffee leaf is parasitic type (Rubiaceous) type. The SA 203 and BP 409 clones have the fewest stomata contents. The content of chlorophyll a, b, and total in the first and third leaves varies between clones. Chlorophyll content in the basal, middle, and apical leaf were relatively uniform, except clones SA 203 and BP 939 for the first leaf, and SA 203 and BP 436 for third leaf. The correlation analysis showed a positive relationship between leaf area and chlorophyll content.</em>
