Abstract

Tolerance of Transgenic Tobacco Expressing P5CS Gene Against Drought Stress. Drought is majorosmotic stress that dramatically limit plant growth and productivity. Proline accumulation has been correlatedwith tolerance to drought stress in plants. Therefore, overproduction of proline in plants may lead to increasedtolerance against these abiotic stresses. The objectives of this experiment were to determine the effects of droughtstress at the period of 15 – 90 days after planting (DAP) on growth of T1 plants derived from transgenic GStobacco, to evaluate their tolerance against drought stress, and to determine their leaf proline content. One groupof the tobacco plants were grown in plastic pots and subjected to stress condition during the period of 15 – 90DAP. The other group was grown optimally in plastic pot up to harvest period. All tobacco plants were harvestedat 91 DAP. Leaf proline content was determined at 63 DAP (after six periods of stress). The results indicatedreduced plant height, shoot diameter, leaf number, leaf dry weight and leaf area of all tobacco plants. Stresssensitivity index calculated using leaf dry weight character grouped T1 plants derived from P5CS transgenicGS tobacco into tolerance, medium tolerance and sensitive against drought stress while that of non-transgenicGS tobacco were only medium tolerance and sensitive against drought stress. Higher leaf proline content underdrought stress was observed in all T1 plants derived from P5CS transgenic tobacco than that of non-transgenicGS tobacco. These data demonstrated that proline accumulation as an osmoprotectant and that over-expressionP5CS gene results in the increased tolerance to osmotic stress in T1 plants derived from P5CS transgenic tobacco.Key words: Proline biosynthesis, proline accumulation, sensitivity index, biomass yield Stres kekeringan merupakan masalah utama stres osmotik yang dapat menjadi faktor pembataspertumbuhan dan produktivitas tanaman. Akumulasi prolina berkorelasi dengan tingkat toleransi tanamanterhadap stres kekeringan. Oleh karena itu over-produksi prolina diduga dapat meningkatkan toleransi tanamanterhadap stres kekeringan. Tujuan penelitian ini adalah (1) untuk mengevaluasi pengaruh stres kekeringanmelalui pengurangan air terhadap pertumbuhan dan hasil tanaman TI zuriat dari tembakau GS transgenik P5CSgenerasi TO, (2) menganalisis akumulasi prolina daun tanaman TI zurlat dari tembakau GS transgenik P5CSgenerasi TO kondisi stres dan non-stres, serta (3) menganalisis hubungan antara akumulasi prolina daun padakondisi stres kekeringan dengan pertumbuhan dan hasil tanaman. Percobaan dua faktor (tembakau transgenikstres kekeringan) disusun dengan rancangan acak kelompok. Sebagian tanaman yang diuji disiram setiap hari hingga mencapai kondisi kapasitas lapang dari awal tanam sampai dengan 90 HST dan digunakan sebagaiperlakuan non-stres. Sedangkan kelompok tanaman yang lain dipelihara dalam kondisi kapasitas lapanghingga 14 HST dan diberi perlakuan stres kekeringan dari umur 15 HST hingga panen (90 HST). Kandunganprolina diukur pada umur 63 HST (setelah 6x periode stres). Hasil penelitian menunjukkan semua tanamantembakau yang diuji mempunyai tinggi tanaman, diameter batang, jumlah, berat kering dan luas daun yanglebih rendah akibat perlakuan stres kekeringan yang diberikan dibandingkan dengan kondisi non-stres.Berdasarkan hasil perhitungan indeks sensitivitas terhadap stres kekeringan menggunakan peubah bobotdaun kering per tanaman maka tanaman TI zurlat dari tembakau GS transgenik P5CS generasi TO yang diujibersegregasi untuk kategori toleran, medium toleran dan peka, sedangkan tembakau GS non-transgenikdikategorikan sebagai medium toleran dan peka terhadap stres kekeringan. Tanaman TI zurlat dari tembakau GStransgenik P5CS generasi TO menunjukkan kandungan prolina yang lebih tinggi dalam kondisi stres kekeringandibandingkan dengan tembakau GS non-transgenik. Peningkatan akumulasi prolina yang cukup tinggi akibatover-ekspresi dari gen P5CS diduga berkorelasi dengan peningkatan toleransi tanaman terhadap stres kekeringan.Kata kunci : Biosintesis prolina, akumulasi prolina, indeks sensitivitas terhadap stres, produksi biomasa

Abstract

Recently, the oil industry has emphasized enhancement oil recovery (EOR) process. The steamflood are ones EOR process can used to increase the heavy oil production. Effective management of EOR process requires detailed reservoir description and observation of the reservoir being swept at time. The 4D microgravity method can be applied in obtaining reservoir description such as steamflood zone mapping. Combination between the rock physics analysis with ideal model of steamflood used to calculate the synthetic 4D microgravity anomaly. This result suggest the negative 4D microgravity anomaly changes at time represented steamflood zones causes by density contras between steam at the high temperature after injection and pressure with heavy oil at the low temperature and pressure before injection. But the 4D microgravity anomaly can’t detect steamflood zone boundaries causes the anomaly shape with respect to shape of source. We proposed the 4D microgravity anomaly constrained with high resolution horizontal derivative to detect steamflood zones boundaries. The field data showed gravity change of up to -300mGal have occurred in area near ones the oil production well.  The maxima value of the field constrained 4D microgravity anomaly represented the steamflood zones boundaries with its surrounding. Key Word :     EOR process, steamflood, rock physics analysis, the constrained 4D microgravity anomaly

Abstract

Abstract. The geodetic approach based on extraterrestrial survey measurements can be used to study phenomenon, especially to monitoring of material movement characteristic. Landslide is one of prominent catastrophe that continuously affecting in Indonesia, especially in rainy season. In mountainous terrain and areas of steep slope of Indonesia, landslides are frequent, especially where land cover has been removed. Landslides destroy not only environment and property, but usually also cause deaths. Landslide mitigation is therefore very crucial and should be done properly. The velocity and acceleration of several monitored point covering the landslide zone area can be estimated using the geodetic approach. Knowing the relation among these three variables in spatial and temporal domain will be useful for identifying the characteristics of landslide. This information can then be used for better strategy of landslide hazard mitigation. Accuracy of the use of kinematic models for prediction of avalanche characteristics need to be validated so that mitigation will be done correctly. Validation is done by doing a comparison between model predictions and the size of the data and statistical tests for the feasibility of prediction of each point of the GPS monitor. Validation is known that the predicted results at some GPS monitor point is not suitable for use. With the vector of the movement of materials, we know the direction and scalar, velocity and acceleration of material displacement. The movement of landslide materials at Ciloto Zone dominated north-west to south-easterly direction and speed to slow very slow (creep). Keywords: accuracy, characteristics, kinematic model, landslide.

Abstract

Modelling studies of Time Domain Induced Polarization (TDIP) performed to obtain the relationship between parameters responses to metallic mineral content. This study includes mathematical, forward, physical and inversion modelling. Mathematical modelling is done by solving the Laplace equation to obtain the IP responses. Forward modelling is done by developing a numerical workflow to generate theoretical curves. Physical modelling obtained the data from various parameters of target measurement. TDIP responses that compared with the theoretical curves are the results of mathematical modelling. The best response of IP can be obtained by inversion modelling. TDIP responses measurement by varying target’s metallic mineral content is done for understanding the relationship between them. The amplitude of IP responses in forward modelling is determined by target’s radius and depth ratio, and ratio of background resistivity and target’s resistivity. The higher target’s radius and depth ratio, the higher the amplitude. There is a good correlation between TDIP responses to the presence of the target and the possibility of metallic mineral content in target.
