    This research paper is aimed at knowing whether or not there is correlation between writing habit and writing skill of sixth semester student of English department of Muhammadiyah University of Surakarta. There are some factors in writing habit such as the people’s desire, motivation, interest, and attitude. The subject of this research is the sixth semester students of English department of Muhammadiyah University of Surakarta. There are 300 students from six classes in this university. The writer uses cluster random sampling in taking sample, and she get 50 students from class C. In collecting the data, the writer gives questionnaire and writing test. The construct validity is used to know the validity of items by using correlation product moment, then to know the reliability the writer uses Alpha Cronbach. The correlation product moment is used to analyze the data. Based on the data calculation, it shows that the obtained rxy is 0.423 when rtable is 0.279 at level of significance 0.05. If the obtained r xy is higher than r table, the obtained rxy 0.423 is positive. So there is positive correlation between writing habit and writing skill. The contribution of writing habit in increasing writing skill is 1,79%. It means that writing habit has role in increasing writing skill, although in contributes small percentage. Finally, the writer finds out that there is positive correlation between writing habit and writing skill of the sixth semester students of English department of Muhammadiyah University of Surakarta

    Liriomyza huidobrensis merupakan hama baru pada tanaman kentang. Hama ini pertama kali dilaporkan menyerangtanaman kentang di Puncak, Jawa Barat pada tahun 1994 dan diduga telah resisten terhadap berbagai jenis insektisidaseperti organofosfat, karbamat, dan piretroid sintetik. Upaya pengendalian diarahkan pada pengendalian hamaterpadu yang penerapannya bergantung pada bioekologi serangga hama. Tujuan dari penelitian ini adalah untukmengetahui dinamika L. huidobrensis dan musuh alaminya, serta pola infestasi pada tanaman kentang di musimkemarau dan musim hujan. Penelitian dilakukan di Kebun Percobaan Balai Penelitian Tanaman Sayuran Lembang,sejak bulan Juni 1999 sampai dengan bulan Pebruari 2000. Rancangan percobaan yang digunakan adalah PetakBerpasangan, terdiri atas dua perlakuan dan diulang enam kali. Hasil penelitian menunjukkan bahwa L. huidobrensismulai menyerang tanaman kentang sejak umur tiga minggu setelah tanam (MST) dan mencapai puncaknya pada umurempat, enam, dan delapan MST. Keberadaan kompetitor sangat mempengaruhi fluktuasi populasi L. huidobrensis.Selain itu faktor lingkungan abiotik seperti suhu, kelembaban, dan angin juga mempengaruhi fluktuasi populasi L.huidobrensis. Keberadaan musuh alami H. varicornis tidak mampu menekan serangan L. huidobrensis. Penggunaaninsektisida bensultaf 50 WP cukup efektif untuk mengendalikan L. huidobrensis. Pada musim kemarau serangan L.huidobrensis lebih tinggi bila dibandingkan dengan musim hujan. L. huidobrensis lebih memilih daun bawah dantengah sebagai tempat peletakan telur.Kata kunci : Solanum tuberosum; Dinamika populasi; Pola infestasi; Liriomyza huidobrensis; Musim kemarau;Musim hujan.AB STRACT.

    Evaluasi ketahanan aksesi wijen terhadap tungau Polyphagotarsonemus latus (Banks) dilakukan di Kebun Percobaan Sumberrejo, Bojonegoro, mulai April sampai Desember 2007.Tujuan penelitian ialah mengetahui tingkat ketahanan aksesi wijen termasuk terhadap keriting daun yang disebabkan oleh P. latus. Perlakuan terdiri atas 25 aksesi wijen disusun dalam rancangan acak kelompok, diulang tiga kali. Pengamatan dilaku-kan mulai 25 hari setelah tanam (hst) dengan interval pengamatan 10 hari sekali sampai 75 hst. Parameter pengamatan meliputi: (1) Skor kerusakan daun (intensitas serangan) pada sepertiga bagian atas tanaman, (2) jumlah telur, larva, nimfa, dan imago P. latus dari daun yang terserang tungau. Pengamatan dilakukan di laboratorium Entomologi Balai Penelitian Tanaman Tembakau dan Serat (Balittas). Hasil pengujian menun-jukkan bahwa satu aksesi tahan yaitu China Hitam; 17 aksesi termasuk kategori agak tahan: Si 50, Si 51, Si 52, Si 57, Si 58, Si 59, Si 60, Si 61, Si 63, Si 65, Si 66, Si 69, Si 75, Sbr 1, Sbr 2, Sbr 3, dan Sbr 4; dan tujuh aksesi termasuk kategori rentan yaitu Si 45, Si 53, Si 54, Si 55, Si 56, Si 62, dan Si 64. Resistance of sesame germ plasm to mite (Polyphagotarsonemus latus Banks) was evaluated at Sumberrejo Experimental Station, Bojonegoro from April to December 2007. The treatment consisted of 25 accessions which were arranged in randomized block design with three replications. The resistance was observed at 10 days interval from 25 days after planting (dap) to 75 dap. The parameters observed were: (1) Score of leave damage intensity; (2) Microscopic observation on total eggs, larvae, nymph, and adult of mites. The results showed that based on leaves damage intensity at 75 dap, one accession was categorized as resistance (China Black); 17 accessions were moderately resistance (Si 50, Si 51, Si 52, Si 57, Si 58, Si 59, Si 60, Si 61, Si 63, Si 65, Si 66, Si 69, Si 75, Sbr 1, Sbr 2, Sbr 3, and Sbr 4); and 7 accessions were susceptible (Si 45, Si 53, Si 54, Si 55, Si 56, Si 62, and Si 64). Total of egg population, larvae, nymph, and adult of mite was positively correlated to leave damage intensity

    Varian Halcyon 2.0 linear accelerator was launched and became available for clinical use in 2018. Therefore, it is necessary to evaluate the accuracy of exit fluence of the Halcyon 2.0 for quality assurance (QA) of head and neck cancer treatment planning, pretreatment, and treatment. The accuracy of the exit fluence for twenty treatment plannings has been evaluated by conducting gamma analysis for QA pretreatment and treatment in each field and composite field by using criteria for gamma index 3 %/3 mm and 2 %/2 mm. The QA pretreatment results are in the average value for each criterion for each field and composite fields on actual gantry angle and null gantry angle with gamma passing rate (GPR) of over 99 % (range 99.78 %-99.95 %) The total treatments consisted of 2717 fractions. The analysis results of GPR for fields were 99.32 % and 97.74 % for gamma indexes of 3 %/3 mm and 2 %/2 mm, respectively. In addition, the analysis results of GPR for composites were 95.46 % and 81.38 % for gamma indexes of 3 %/3 mm and 2 %/2 mm, respectively. Based on this result, the average GPRs of QA pretreatment are ≈ 99 % of the total pixels. This means the prediction dose of Varian Halcyon 2.0 is accurate. The average GPRs of treatment is nearly  90 %, showing that Varian Halcyon 2.0 is effective for creating treatment plans for complex cases

    Efficacy of liquid smoke from laban wood (Vitex pubescens) against Coptotermes curvignathus. Antitermitic activities of liquid smoke produced from Vitex pubescens against C. curvignathus was evaluated in this study. This research was conducted in two steps, i.e. pyrolisis of liquid smoke and efficacy test of liquid smoke as antitermite. Three kinds of liquid smoke were produced at three different pyrolysis temperatures, i.e. 350 oC, 400 oC and 450 oC. Termiticidal activity was evaluated by a no-choice test. The research indicates that concentration of liquid smoke and pyrolysis temperatures significantly affected termite mortality and mass losses of the filter paper. The relationship between the concentration of liquid smoke (X) and termite mortality (Y) at 350 oC, 400 oC, and 450 oC were Y = 31,4 + 11,76X, (r2 = 0,60), Y = 30 + 11,86X (r2 = 0,59), and Y = 26,66 + 7,6X (r2 = 0,429). The relationship between concentration of liquid smoke (X) and mass losses (Y) at 350 oC, 400 oC, and 450 oC were Y= 85,12 -3,188X (r2 = 0,723), Y= 88,06 – 3,435X + (r2 = 0,953) and Y= 91,56 – 3,867X (r2 = 0,886)

    Energy audit is very necessary to calculate the level of energy consumption of a building or buildings. The research includes the amount of energy consumption based on the initial energy audit and detailed energy audit as well as saving opportunities based on conditions in the field. Based on the initial energy audit, the value of the Energy Consumption Intensity (IKE) is 0.699 kWH/m2month, while in the detailed audit the IKE value is 0.935 kWH/m2month. Based on the results of a detailed energy audit, the lighting measurement of 325 lux still meets the requirements for a classroom with a standard between 250 lux to 500 lux
