In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 704-711.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Tungro is one of the important diseases in rice plants. Tungro disease in Indonesia has infected crops on a large scale in the 1960s. This disease causes a decrease in crop production by up to 80%, it can even cause puso. Line testing is one of the stages of the long process of creating a variety. The advanced yield test is the final stage of testing a line before the multi-location test is carried out. The purpose of this study was to select tungro-resistant promising rice lines that have high yield potential. In this study, there were 9 test lines used, with the comparison variety Mekongga, which were designed using a Randomized Block Design (RAK) with 3 replications. The results showed that the parameters of panicle number, panicle filled grain, panicle empty grain, and dry milled grain production were not significantly different between the comparison varieties and the nine lines tested. The comparison varieties showed that the plant height, weight of 1000 seeds and panicle length were significantly higher than the test lines. There were no test lines that showed better performance than the comparison variety, Mekongga

Ketahanan 50 galur harapan padi terhadap penyakit tungro

Green leafhoppers is the main vector for tungro disease infection. Tungro is a rice disease which is characterized with stunted plants, yellow orange leaves, and a reduced number of tillers. The research aimed to determine the resistance of 50 rice lines to tungro disease. This research was conducted in Augmented Design with 5 blocks. The observation was held on 50 expected tungro resistant rice lines, with 2 check varieties, Inpari 36 and Ciherang. Experiment in field were included observation on number of imago and nymph green leafhoppers for each line test during 2, 4, 6 and 8 weeks after planting, and the incidence of tungro infection. Leaf which indicated tungro infection was isolated for its DNA and PCR analysis at the virology  laboratory of the tungro disease research station. The results showed that the number of green leafhopper (imago and nymph) for the  43 test lines were less than the check varieties of 5% LSI test. The incidence of tungro was very low in the field. The results of the PCR test showed that the rice line infected by tungro virus was only rice line number 7. Thus, there are 43 promizing lines that can be recommended for future research to obtain tungro resistant varieties.ABSTRAK Wereng hijau merupakan vektor utama penyebaran penyakit tungro.

PENGARUH APLIKASI PUPUK SILIKA DALAM PENGENDALIAN TUNGRO

Tungro adalah salah satu penyakit penting pada padi, yang disebabkan oleh dua jenis virus, yaitu Rice Tungro Bacilliform Virus (RTBV) dan Rice Tungro Spherical Virus (RTSV), melalui vektor wereng hijau (Nephotetic virescens). Tingginya intensitas pertanaman menyebabkan keseimbangan unsur hara semakin berkurang, termasuk unsur silika (Si). Pemberian pupuk silika dengan dosis yang tepat dapat meningkatkan kesuburan tanah dan menyebabkan tanaman lebih tahan terhadap serangan hama penyakit. Tujuan penelitian ini untuk mengkaji pengaruh pemberian pupuk silika dalam pengendalian penyakit tungro. Penelitian menggunakan rancangan faktorial dua faktor. faktor pertama yaitu dosis pemberian pupuk silika (kontrol, NPK dosis umum digunakan petani, 1/3 NPK + 1 lt si, 1/3 NPK + 3 lt si, 1/3 NPK + 5 lt si), faktor kedua adalah penggunaaan varietas (inpari 36 dan TN1). Hasil penelitian menunjukkan bahwa interaksi pemberian dosis pupuk silika dan varietas tidak berpengaruh nyata terhadap semua parameter pengamatan, kecuali pada hasil gabah. Varietas berpengaruh nyata terhadap tinggi tanaman, panjang malai, dan hasil gabah

Translation Analysis: Syntactic, Semantic, and Pragmatic Strategies Used in Translating A Website of an Academic Institution

This research aims to discover the emerging translation strategies and the types of translation strategies most frequently used on a website of an academic institution. In finding the data, the researcher employs the descriptive qualitative method by applying the translation strategy theory proposed by Andrew Chesterman in the form of syntactic, semantic, and pragmatic strategies on a website of an academic institution such as the Universitas Hasanuddin website. There are 11 emerging translation strategies on the website; 4 Syntactic Strategies (Literal, Loan/Calque, Transposition, and Phrase Structural Change), 4 Semantic Strategies (Synonymy, Hyponymy, Distribution Change, and Pharaprase), and 3 Pragmatic Strategies (Explicitness Change, Information Change, and Transediting). The result shows that the most frequently used translation strategy is Syntactic Strategies (Literal 60% or 44 data, Loan/Calque 23% or 17 data, Transposition 8% or 6 data, and Phrase Structural Change also 8% or 6 data). Then the second one is Semantic Strategies (Synonymy 7% or 1 datum, Hyponymy 7% or 1 datum, Distribution Change 64% or 9 data, and Pharaprase 21% or 3 data), and last is Pragmatic Strategies (Explicitness Change 8% or 1 datum, Information Change 85% or 11 data, and Transediting 8% or 1 datum)

Pengaruh Cekaman Kekeringan dan Umur Panen Terhadap Pertumbuhan dan Kandungan Xanthorrhizol Temulawak (Curcuma xanthorrhiza roxb.)

The research was conducted from November 2005 until May 2006 to determine growth and production of the Curcuma xanthorrhiza based on agronomical, physiological variables, and bioactive (xanthorrhizol) content.  The experiment was arranged in a completely randomized design with two factors and three replications.  The first factor consisted of 4 level of drought stress i.e: 100% field capacity (FC) (as control), 50% FC started at 2 weeks before harvesting (wbh),  50% FC started at 4 wbh,  and 50% FC started at 6 wbh.  The second factor comprised of 2 harvest times i.e. 5 months and 7 months.  The result showed that drought stress decreased plant growth and productivity, but increased accumulation of proline.  The harvesting time significantly increased the agronomic character, but did not significantly increase proline content.  The older samples contained more xanthorrhizol than the younger samples.   Key words: Curcuma xanthorrhiza, drought stress, harvesting time, plant growth,  xanthorrhizol

Formations effect of brass plate anode on electroplating thickness uniformity: case study on wheelchair headrest

Uniformity of coating thickness in the electroplating process of cylindrical objects using plate-shaped anodes has become a challenging issue. One electroplating method uses a cylindrical anode. However, this strategy is too expensive and requires a lot of material. This paper determines the effect of brass plate anode formation on the headrest thickness uniformity of the electroplating brass coating on the headrest connector of electric wheelchairs made of St. 37. The research started by making headrest connector using a turning machine, then plating the brass using the electroplating method, and then testing the thickness of the resulting brass for uniformity of data using statistics. The number and placement of the plate anodes varied with 2 symmetrical position anodes, 3 symmetrically spaced anodes, and 4 symmetrically positioned anodes. Coating thickness was measured using a digital microscope with a magnification of 200 times. Before measuring the thickness of the coating, the surface of the joint is milled first to remove any chamfer on the top surface of the body and the cover headrest connector. The surface is smoothed using sandpaper and cleaned using etching. Data from the uniformity test results show the highest level of uniformity in the variation of 4 anodes on the body and the cover of the headrest connector, followed by variations on the 3 anodes on the body and the cover of the headrest connector, and variations of 2 anodes on the body and the cover of the headrest connector. The greater the number of anodes and their placement around the cathode, the higher the thickness uniformity of the resulting brass electroplating layer. The formation of brass plate anode on electroplating affects headrest thickness uniformit
