Abstract

Microalgae Chlorella pyrenoidosa and Dunaliella salina have been used as natural aquaculture food supplement because the previous contains 60,5% proteins and 180,8 mg/100g β-carotene and the other  were accumulated β-carotene by 95% from their total carotenoid.  Carotenoid  production can be improved by protoplast fusion technique. The aim of the research was conducted protoplast fusion of from C. pyrenoidosa and D. salina in order to gaining boarder salinity spectrum for natural aquaculture food supplement . The research metodology consist of protoplast  isolation followed by protoplast fusion process  induced by PEG6000 and regeneration of  fusant.  Protoplast fusion was done in three different PEG incubation time that are 15, 30 and 45 minutes.  The fusants were grown in 2 different medium, sea water media and fresh water media.  Research result shows that optimal fusion incubation time with PEG6000 is at 30 minutes.  Fusant can grown in both  medium and revealed higher β-carotene contents 2,008 µg/ml comparing with their parents.   Keywords: Protoplast fusion, Chlorella pyrenoidosa, Dunaliella salina, β-carotene.

Abstract

Ketergantungan pestisida pada sentra produksi bawang merah Kabupaten Tegal telah menimbulkan pencemaran logam berat kadmium (Cd) di dalam tanah dan tanaman bawang merah. Kadar logam tersebut telah melebihi ambang batas yang dapat mengganggu kesehatan manusia. Tujuan penelitian ini adalah melakukan analisis kandungan kadmium pada akar, daun dan umbi tanaman bawang merah dari Tegal. Metode penelitian dilakukan melalui analisis kandungan logam berat kadmium dalam tanaman bawang merah  dibandingkan dengan kontrol menggunakan metode spektrofotometri atom absorbansi (AAS). Hasil penelitian memperlihatkan kandungan kadmium pada umbi, daun dan akar bawang merah di Tegal pada umur 20 hari berturut-turut adalah sebagai berikut 3,4805 mg/g; 4,1374 mg/g dan 7,9175 mg/g. Kandungan kadmium pada umbi, daun dan akar bawang merah umur 50 hari atau usia panen berturut-turut adalah sebagai berikut 1,8331 mg/g; 1, 8331 mg/g dan 3,5323 mg/g. Hasil penelitian yang diperoleh menunjukkan konsentrasi kadmium yang melampaui batas ambang aman bagi makanan, kesehatan dan lingkungan.    Pesticide dependence on onion production centers Tegal has caused heavy metal pollution of cadmium (Cd) in the soil and plant onions. This metal content exceeds the threshold that can impair human health. The purpose of this study was to analyze lead content in root, leaves and bulb of red onion from Tegal. Research methods to analyze the content of heavy metals in the soil compared to the control using atomic absorbance spectrophotometry (AAS). The research results showed lead content in roots, leaves and roots of onion at the age of 20 days in a row is as follows 3,4805 mg/g; 4,1374 mg/g and 7,9175 mg/g. The results obtained shows that cadmium concentrations exceed safe thresholds for food, health and the environment.

Abstract

Energy needs in fuel sector tend to increase for supporting human life. Green microalgae (Chlorophyceae) can be used as an alternative solutions for bioenergy. Botryococcus braunii is lipid producer microalgae which can be processed further into biodiesel. Microalgae growth medium such as Walne can be substituted with coconut water that reducing economical cost. This research aims to determine the growth of B. braunii using coconut water and its effect on lipid production. The experiment conducted into five treatments of coconut water consist of P0 (0%), P1 (10%), P2 (7.5%), P3 (5%), and P4 (2.5%) for five days incubation and three repetitive step. Microalgae growth was calculated according to cell count using hemocytometer. The results showed that 2.5% coconut water substitution exhibited the best growth rate and lipid production, i.e. the amount of 547 cells / ml and produced lipid level according to these treatment increased 179% comparing with control.
Analisis Fusan Hasil Fusi Protoplas Intraspesies Pichia manshurica DUCC-015 (Analysis of Fusant from Protoplast Fusion Intraspecies of Pichia manshurica DUCC-015) Roslenawati, Roslenawati; Kusumaningrum, Hermin Pancasakti; Pujiyanto, Sri

Abstract

The intraspecies protoplast fusion of P. manshurica DUCC-015 was conducted in searching the fusant with greater inulinase production. Inulinase on Dahlia variabilis Willd tuber from Baturraden-Purwokerto showed inulinase activity 0,683 IU/mL. Inulinase is an enzyme that catalyzes the hydrolysis reaction of inulin polysaccharides into fructose and or fructooligosacarides. The aims of this research was revealing fusant from intraspecies protoplast fusion process of P. manshurica DUCC-015 followed by analyzing of their inulinase productivity and activity. The research metodology protoplast fusion process consist of lysis of cell wall, protoplast fusion and regeneration of intraspecies fusant P. manshurica DUCC-015. Analysis of fusant were done by Schiff Basic Fuchsin staining of fusant nuclei, also measuring the inulinase activity and inulinase production comparing with their parent. The inulinase activity will be analyzed by T-Test Independent Two Sample on 95% Confidence interval of the difference use Statistical Product and Service Solution programme (SPSS). The result of experiment gaining fusant with regeneration capability, ploidi diversity  of fusant, inulinase activity about 0,965 IU/mL while their parent 0,622 IU/mL and inulinase production 0,736  IU/mL comparing with 0,731 IU/mL during 42 hours incubations. The fusant indicated the increase of inulinase activity and production  compared with their parent.   Keywords: Pichia manshurica DUCC-015, fusant, inulinase    Fusi protoplas intraspesies Pichia manshurica DUCC-015 telah dilakukan untuk mencari fusan dengan produksi inulinase yang lebih tinggi. Inulinase pada umbi tanaman Dahlia variabilis Willd dari Baturraden-Purwokerto memperlihatkan aktivitas sebesar 0,683 IU/mL. Inulinase merupakan enzim yang mengkatalisis reaksi hidrolisis polisakarida inulin menjadi fruktosa dan atau fruktooligosakarida. Penelitian ini bertujuan untuk mendapatkan fusan hasil fusi protoplas intraspesies P. manshurica DUCC-015 yang memiliki aktivitas inulinase lebih tinggi. Rancangan percobaan fusi protoplas terdiri dari isolasi protoplas, fusi protoplas dan regenerasi fusan. Analisis fusan menggunakan pewarnaan  Fuchsin pada inti sel, mengukur aktivitas dan produksi inulinase fusan. Aktivitas inulinase dianalisis dengan Uji T Test Dua Sampel Independen pada taraf kepercayaan 95% menggunakan program Statistical Product and Service Solution (SPSS). Hasil penelitian menunjukkan fusi protoplas intraspesies P. manshurica     DUCC-015 menghasilkan aktivitas inulinase mencapai 0,965 IU/mL dibandingkan induk sebesar 0,622 IU/mL dan produksi inulinase 0,736  IU/mL pada inkubasi selama 42 jam. Fusan  mengindikasikan kenaikan aktivitas dan roduksi inulinasi dibandingkan induk. Kata kunci : Pichia manshurica DUCC-015, fusan, inulinase.
