Rice Tolerance to Flooding Stress on Germination Stage and Early Seedling Growth under 5 cm Water Depth

Flood is one of the major environmental constraints that may harm plant productivity which requires specific mechanism to cope with stress. Flood prone area where rice is major crop to be cultivated, transplanting method on cultivation system cost high labor with consequence on low seedling survival. Direct seeding may offer solution for this condition with additional improvement needed on seed tolerant to germinate on anaerobic environment. An experiment was conducted to evaluate 23 rice varieties of tolerance to flooding stress on germination stage under 5 cm water depth. The experiment design was Nested – Randomized Complete Block Design with two factor and three replications. Result showed that rice germination under anaerobic condition was varied with Lambur has highest survival rates among others. Tolerance level was characterized from higher survival ability followed by high biomass accumulation and length of the shoot and root.Keywords: anaerobic germination, direct seedin

Utilization of amelioration and bioremediation to reduce Al stress in upland rice “Inpago 12”

The contribution of rice production in drylands (upland rice) to national rice production is still low, due to several limiting factors including limited water, low pH, and low soil fertility. This study aimed to obtain improved recommendations for amelioration and bioremediation in drylands with Al stress to enhance rice production. The upland rice variety of Inpago 12 was planted at Taman Bogo Experimental Farm, East Lampung in the first planting season of 2020. The experiment was arranged in a split-plot design with three replications. The main plot was the application of amelioration materials consisting of control (without amelioration), CaMg(CO3)2, CaCO3, and rock phosphate. The subplot was the application of bioremediation materials consisting of control (without bioremediation), biofertilizer, endophytic microbes, and citric acid. Results showed that amelioration and bioremediation on dry land with low to moderate Al stress and high Al stress did not significantly increase the growth of rice plants. However, bioremediation in the form of citric acid on land with low to moderate Al stress significantly increased grain production by 6.21% than without bioremediation.

A Macroecological Analysis of SERA Derived Forest Heights and Implications for Forest Volume Remote Sensing

Individual trees have been shown to exhibit strong relationships between DBH, height and volume. Often such studies are cited as justification for forest volume or standing biomass estimation through remote sensing. With resolution of common satellite remote sensing systems generally too low to resolve individuals, and a need for larger coverage, these systems rely on descriptive heights, which account for tree collections in forests. For remote sensing and allometric applications, this height is not entirely understood in terms of its location. Here, a forest growth model (SERA) analyzes forest canopy height relationships with forest wood volume. Maximum height, mean, H100, and Lorey's height are examined for variability under plant number density, resource and species. Our findings, shown to be allometrically consistent with empirical measurements for forested communities world-wide, are analyzed for implications to forest remote sensing techniques such as LiDAR and RADAR. Traditional forestry measures of maximum height, and to a lesser extent H100 and Lorey's, exhibit little consistent correlation with forest volume across modeled conditions. The implication is that using forest height to infer volume or biomass from remote sensing requires species and community behavioral information to infer accurate estimates using height alone. SERA predicts mean height to provide the most consistent relationship with volume of the height classifications studied and overall across forest variations. This prediction agrees with empirical data collected from conifer and angiosperm forests with plant densities ranging between 102–106 plants/hectare and heights 6–49 m. Height classifications investigated are potentially linked to radar scattering centers with implications for allometry. These findings may be used to advance forest biomass estimation accuracy through remote sensing. Furthermore, Lorey's height with its specific relationship to remote sensing physics is recommended as a more universal indicator of volume when using remote sensing than achieved using either maximum height or H100

Apology strategies used by the main characters of The Fault In Our Stars Movie

ABSTRACT This study focuses on analyzing apology strategies which are used by the main characters in The Fault in Our Stars movie. This study applies qualitative method in finding apology strategies used. In analyzing the data, the researcher follows four steps: (1) finding out the context to understand the condition and utterances of apology expression, (2) classifying the data into five types of apology based on Cohen and Olhstain’s theory, (3) explaining and interpreting the data from each category in “The Fault In Our Stars” movie, and (4) drawing the general conclusion based on the research finding to answer the research problems. The result of this study shows the types of apology strategies used by the main characters of The Fault in Our Stars movie, which include expression of apology consisting of an expression of regret, an explanation or account of the situation, an acknowledgment of responsibility consisting of accepting the blame, and offer of repair. The findings also find some data which contain multiple strategies, those are an expression of apology with an explanation or account of the situation, an expression of apology with acknowledgment of responsibility (accepting the blame, expressing lack of intent, and recognizing other person as deserving apology), and an expression of apology with offer of repair. From these data, using of internal intensifiers, such as so and very, are also used to show sincere apology. The researcher finds some message behind the most dominant of apology strategy. The main characters mostly use an expression of regret with an explanation because to maintain the close relationship and to minimize the severity of the offense. To show polite apology, they mention what behavior or cause may bring about a violation of social norms. Finally, the researcher suggests that this study is useful for the readers in understanding the concept of apology strategies. Also, the next researcher can examine apology strategies by using other theories, different media, and some related issues which need further investigation.

Hasil penelitian menunjukkan bahwa jenis-jenis strategi permintaan maaf yang digunakan oleh peran utama di film The Fault In Our Stars meliputi ekspresi permintaan maaf yaitu ekspresi penyesalan, strategi memberikan penjelasan atau alasan berdasarkan situasi, strategi pengakuan pertanggungjawaban yang terdiri dari menerima kesalahan, dan strategi menawarkan perbaikan. Selain itu, penggunaan beberapa kombinasi strategi juga ditemukan dalam penelitian ini, yaitu ekspresi permintaan maaf dengan strategi memberikan alasan, ekspresi permintaan maaf yang digabung dengan strategi pengakuan pertanggungjawaban (menerima kesalahan, ekspresi ketidaksengajaan, mengakui kesalahan dari orang lain), dan ekspresi permintaan maaf dengan memberikan perbaikan. Penggunaan penekanan internal dalam meminta maaf, seperti so dan very berfungsi untuk menunjukkan keihlasan dan tulus hati. Peneliti menemukan beberapa informasi dan gagasan mengenai strategi permintaan maaf yang paling banyak digunakan. Pemeran utama dalam film The Fault in Our Stars sering menggunakan kombinasi ekspresi permintaan maaf dengan strategi memberikan alasan dibalik kesalahannya karena untuk menjaga hubungan karib dan mengurangi kegentingan situasi. Permintaan maaf yang sopan dapat ditunjukkan dengan menyebutkan tindakan apa atau penyebab seseorang melakukan kesalahan. Peneliti mengusulkan bahwa hasil penelitian ini bermanfaat bagi pembaca dalam memahami dan mendalami konsep strategi permintaan maaf. Selain itu, bagi para peneliti selanjutnya dapat meneliti strategi permintaan maaf dengan menggunakan teori yang lain, media yang berbeda, dan beberapa fenomena bahasa lain yang terkait dengan permintaan maaf yang membutuhkan penelitian lebih lanjut

The use of a radar backscatter model to assess the sensitivity of multi-frequency, -polarisation, and -angle SAR data for detecting the growth stage of oil-palm plantations

Increasing interest in SAR data for forest monitoring has encouraged the use of SAR sensors with varying frequency, polarisation and incidence angle. As microwave signals of different frequencies and polarisations interact with different parts of tree canopies in a characteristic manner, a physical model can assist in understanding how tree growth and canopy changes affect microwave back scattering signatures. The model can be used to conduct sensitivity analysis to these changes, and this sensitivity assessment will enable the recommendation of optimum radar parameters to be employed, thus improving the effectiveness of such a monitoring task. This research has adapted and employed a three-dimensional radar backscatter model previously developed by Sun and Ranson (1995) to assess the sensitivity of ERS and JERS SAR data for detecting the growth stage of oil-palm plantations, In performing this assessment, the model is run at various oil-palm tree growth stages to assess the sensitivity of different radar configurations. Results from this sensitivity analysis show that ERS CVV and JERS LHH SAR configurations are not optimal for such task. While ERS CVV performs better than JERS LHH for detecting the growth stage of Oil-Palm plantation at 4, 8 and 12 years old, the optimum single frequency/polarisation combination is shown to be CHV. Results from the simulation also show that the sensitivities of X-, C- and L-band are significantly affected by the condition of the ground surface underneath the plantation. As the ground condition can vary significantly, from swamp to understory and plantation litter, any attempt to differentiate the growth stage of such plantations will be very difficult without prior knowledge of the ground conditions. Simulation results suggest that the use of multi-frequency, -polarisation and -angle data, however, enable the differentiation of the major scattering mechanisms and a characterisation of the ground condition. Using this information, simple methods to differentiate the ground condition and the plantation growth stages at various ground surface condition are proposed
