"Usaha peningkatan produksi garam nasional belum berkembang, termasuk dalam usaha peningkatan kualitasnya. Peningkatan kualitas garam rakyat dapat dilakukan dengan pengendalian air laut sebagai bahan baku garam melalui teknik bioabsorbsi bahan pengotor berupa kalsium dan magnesium. Penelitian dilakukan dengan memanfaatkan Gracilaria sp. sebagai bioabsorben kalsium dan magnesium. Hasil penelitian menunjukkan keberadaan Gracilaria sp. tidak berpengaruh nyata terhadap perubahan kandungan kalsium dan magnesium pada perairan tambak. Kandungan rata-rata kalsium pada tambak kontrol ±878,26 mg/liter dan tambak perlakuan ±977,41 mg/liter. Namun demikian terdapat korelasi positif yang signifikan (sig.=0,814) antara lama waktu penanaman dan kandungan kalsium dalam rumput laut dengan kandungan kalsium tertinggi ±1.306,5 mg/100g terjadi pada hari ke-75. Adapun lama waktu penanaman dan kandungan magnesium dalam Gracilaria sp. terjadi korelasi negatif yang kuat (sig.= -0,673) yaitu ±36,10 mg/100g pada hari ke-75. Terdapat juga korelasi positif secara kuat antara kandungan kalsium pada Gracilaria sp. dengan salinitas dan pH perairan. Disimpulkan bahwa pemanfaatan rumput laut jenis Gracilaria sp. sebagai bioabsorben mampu menyerap kalsium sebagai pengotor dari air bahan baku garam, dan belum mampu secara optimal untuk penyerapan magnesium pada perairan tambak garam. Atas hasil penelitian disarankan dilakukan penelitian lebih lanjut untuk mendapatkan manfaat dari Gracilaria sp. secara optimal sebagai bioabsorben pada tambak garam. Penelitian lanjutan di antaranya melalui teknik penanaman Gracilaria sp. sebagai bioabsorben paling efektif sehingga mendapatkan kualitas air bahan baku garam yang paling tepat.

The efforts to increase the national salt production has not been growing, including to improve its quality. To increase the quality of traditional salt can be done by controlling the sea water quality as raw material through bioabsorbtion salt impurities techniques, such as calcium and magnesium. The study was conducted by utilizing bioabsorbent Gracilaria sp.. The results showed the presence of Gracilaria sp. did not significantly influence the changes of calcium and magnesium content in the water of salt pond. The average content of calcium in the control pond was 878.26 mg/liter and the treatment ponds 977.41 mg/liter. However, positive correlations significantly occurred (sig. = 0.814) between duration of planting and calcium content in Gracilaria sp. with the highest calcium content that was 1306.5 mg/100g occurred in the 75th day. The duration of planting and the content of magnesium in Gracilaria sp. showed negative correlation (sig. = -0.673) that was 36.10 mg/100g on the 75th day. There was a strong positive correlation between calcium content in Gracilaria sp. with salinity and pH of the water. The research concluded that the use of Gracilaria sp. as bioabsorbent was able to absorb calcium as impurities from salt pond water. Contrary, it was unable to optimize the absorption of magnesium in the water of salt pond. It is recommended to continue research to get the optimal benefits of Gracilaria sp. as a bioabsorbent in the brackishwater ponds. It is suggested to alter the seaweed cultivation techniques as bioabsorbent to get the most appropriate quality of raw material salt water."

"ABSTRACTBiological control of postharvest diseases of fruits and vegetables byantagonistic microorganism seems increasingly promising to replace the use of synthetic fungicides which are subjected to some limitation due to development of fungicides-resistant strain of the pathogens and risk for consumers and the environment (Lima et al, 1999). Several species of yeast have been reported to reduce postharvest fungal decay on fruits. One of the antagonistic yeast that has been use as commercial biocontrol is Metchnikowia fructicola in Shemerm product (Vero et al., 2002) Yeast Rhodotomla has been studied for the postharvest biologicalcontrol various mould pathogens on various fruit (Castoria et al., 1997).University of Indonesia Culture Collection (UICC) have Rhodotorula spp.strains from plants of Cibodas Botanical Garden, and moulds frompostharvest decayed-tomatoes and plants. The ability of these yeast strains as biocontrol agents against has not been reported.This thesis consists of two parts. Part 1 is entitled The antagonisticActivity of Rhodotorula spp. from Cibodas Botanical Garden Against Tomato Plant Infected-Causing Moulds. Part 2 is entitled The Potential of Rhodotorula sp. UICC Y-381 as Biocontrol Agent of Aspergillus ochraoeus on Postharvest Tomatoes. The objectives of this research are to obtain a potential Rhodotorula sp. with antagonistic activity against tomato infected-causing moulds, and to obtain infoimation on the ability of Rhodotorula sp. UICC Y- 381 as a biocontrol agent in reducing the severity of decay by Aspergillus ochraceus. The research was carried out in Laboratory of Microbiology, Department of Biology, and Center of Excellence Indigenous Biological Resources-Genome Studies (CoE IBR-GS), Faculty of Mathematics and Natural Sciences, from July 2008-July 2009.Yeast Malt Agar (YMA) was used for yeast growth medium, and PotatoDextrose Agar (PDA) was used for maintenance of fungi. The media PDA and Potato Dextrose Agar (PDB) were used for antagonistic test.Six strains of Rhodotorula spp. (Rhodotorula sp. UICC Y-318,Rhodotorula sp. UICC Y-325, Rhodotorula sp. UICC Y-332, Rhodotorula sp. UICC Y-381, Rhodotomla sp. UICC Y-384, and Rhodotorula sp. UICC Y-386) were investigated as antagonistic yeasts against Aspergillus ochraceus D1.2.2.SSM3, A. terreus D2.2.MC, and Drechslera sp. D1.3.MC. The yeasts were obtained from plants of Cibodas Botanical Garden, and the moulds were obtained from decayed tomatoes and infected plants, belonging to the University of Indonesia Culture Collection (UICC). Antagonistic test by strip method was carried out by usingconcentration of yeast cells at (1 .2-5.2) x 10° CFU/ml, and A. ochraceusD1.2.2.SSM3 at 4.7 x 10? CFU/ml, A. terreus D2.2.Mc at 3.2 x 10° CFU/ml,and Drechslera sp. D1.3.MC at 5.2 x 10? CFU/ml. Inoculation of the yeastcells on PDA was carried out 4 hours earlier before inoculation of mouldspores on petri dishes. Results showed that highest percentage reduction of mould colonies was shown by Rhodotorula sp. UICC Y- 325 againstDrechslera sp. (28.12%-72.14%), followed by Rhodotorufa sp. UlCC Y-381 against A. ochraoeus (54.28%-72.46%), and Rhodotoruta sp. Y-318 against A. terreus (21.76% - 58.10%) during 6-day incubation.Antagonistic test by co-culture method was carried out by usingconcentration of yeast cells at (1 .58-5.59) x 10° CFU/ml, and Aspergillus ochraceus D1.2.2.SSM3 at 7 x 10? cFU/ml, A. terreus D2.2.MC at 1.5 x 10? CFU/ml. Inoculation of the yeast cells on PDB was carried out 8 hours earlier before inoculation of mould spores on broth medium. Results showed that highest percentage reduction of conidial heads and hyphal width was shown by Rhodotorula sp. UICC Y-381 against A. ochraceus (9.45% and 12.43%; 7.10% and 7.51 %, after 2- and 3-day incubation, respectively). Rhodotorula sp. UICC Y-332 reduced conidial heads of A. terreus (10.17% and 9.60% after 2- and 3-day incubation) but, was not able to reduce hyphal width of A. terreus. Microscopic observation by slide culture method on PDA showed that there was attachment of Rhodotorula spp. cells to the hyphae of Drechslera sp., however, Rhodotorula spp. UICC Y-386 attached more intensively and colonized the hyphae.The ability of Rhodotorula sp. UICC Y-381, which was isolated fromplant leaves, as a biocontrol agent against postharvest tomato fruit decay- causing mould Aspergillus ochraceus D1 .2.2.SSM3 was evaluated. Observation was carried out for 15 days at 25°C - 27°C. Results showed that Rhodotorula sp. UICC Y-381 was able to reduce the severity of decay by A.ochraceus with 100% reduction until day-12, when compared to control. The synthetic fungicide Dithane M-45 at a concentration of 0.08% reduced the severity of decay to 100% until 15-day incubation."
