The object of the study is to know some effectivenes fungicides
againts plant purple strain disease Alternaria porri Ell. Cif on red onion.
The reseach was done in Tongging, Kabupaten Karo above 500
m from sea level. Reseach starting in April until July 2007.
Reseach applies Non Factorial Randomized Block Design (Non
Factorial RAK) which consist of F0 (control/non act), F1 (Sirih leaf
extracts), F2 (Mimba leaf extracts), F3 (Gambir) and F4 (fungicide Dithane
M-45 80 WP) as compared. The parameter perceived intensity attack (%)
percentage of attack (Alternaria porri) and shallot production (Ton/ha).
The result of the study shows that values of natural fungicides,
significantly influences after aplication to the intensity of attack from
Alternaria porri Ell. Cif. The highest value range of each found on act F3
(gambir) about 18,72 % and the lowest found on F1 (sirih leaf extracts)
about 15,67 %. Highest production found on F1 about 10,4 Ton/Ha and

IRR 118, IRR 104, BPM 107, BPM 109, PB 217. C. gloeosporioides isolate from
Sumut (Sungai Putih), Palembang (Sembawa), Jawa tengah (Salatiga), and control
(used aquadest steril). The result of research showed that the clone BPM 109 (K9)
is a resistant clone, clone BPM 24 (K1) is a moderat clone, and the other clones
were is a middle resistant. Periode latent to all isolate except control to 2 hsi was a

Get PDFPenilitian ini bertujuan untuk mengetahui hubungan self efficacy dan dukungan sosial dengan kecemasan siswa menghadapi Ujian Nasional Berbasis Komputer (UNBK) di Sl\.1K PAB 12 Saentis. Jenis penelitian ini adalah kuantitatif korelasional. Populasi dalam penelitian ini adalah 226 siswa-siswi kelas XII SMK P AB 12 Saentis. Teknik pengambilan sampel menggunakan teknik proporsional random sampling. Sampel sebanyak 70 orang siswa yang mengalami kecemasan. Penelitian ini menggunakan 3 (tiga) skala yaitu skala kecemasan siswa, skala self efficacy dan skala dukungan sosial. Teknik analisis data menggunakan analisis regresi ganda. Berdasarkan hasil analisis data diperoleh ( 1) Terdapat hubungan negatif dan signifikan antara self efficacy dengan kecemasan siswa dimana fx1y = -0,258 dan p = 0,033 (p < 0,05) (2) Terdapat hubungan negatif dan signifikan antara dukungan sosial dengan kecemasan siswa dimana rx2y = -0,534
dan p = 0,000 (p < 0,05) (3) Terdapat hubungan yang signifikan antara self efficacy dan dukungan sosial secara bersarna-sama dengan kecemasan siswa diperoleh koefisien Freg = 20,648 dimana p = 0,00 (p < 0,05). Sumbangan efektif self efficacy dan dukungan sosial dengan kecemasan siswa 38, 1 %
Hubungan Kontrol Diri dan Harga Diri dengan Kecerdasan Moral Siswa SMK Sinar Husni 2 TR Labuhan Deli

diri dengan
kecerdasan moral siswa SMK Sinar Husni 2 TR Labuhan Deli dengan populasi berjumlah 710 orang siswa. Sampel penelitian berjumlah 107 orang siswa SMK Sinar
Husni 2 TR
Labuhan Deli. Metode yang digunakan dalam penelitian ini adalah metode
kuantitatif
dengan teknik pengambilan sampel menggunakan teknik simple random sampling.
lnstrumen yang digunakan adalah angket model skala Likert, analisis data menggunakan
analisis regresi berganda. Berdasarkan basil penelitian disimpulkan bahwa: 1) terdapat
hubungan positif yang signifikan antara kontrol diri dengan kecerdasan moral siswa
dengan nilai koefisien korelasi (rx1 y) sebesar 0,686 ; 2) terdapat hubungan positif
yang
signifikan antara harga diri dengan kecerdasan moral siswa dengan nilai koefisien
korelasi
(rx2y) sebesar 0,205; serta 3) terdapat hubungan positif yang signifikan antara
kontrol diri
dan harga diri dengau kecerdasan moral siswa, hasil ini ditunjukkan dengan
F= 47,205
dan p = 0,001, p < 0,05. Ini menandakan bahwa semakin tinggi kontrol diri dan
harga diri
siswa maka semakin baik kecerdasan moral siswa. Kontrol diri memberi kontribusi
terhadap kecerdasan moral sebesar 47,5% dan harga diri memberikan
kontribusi
terhadap kecerdasan moral sebesar 4,2%. Kontribusi kontrol diri dan
harga diri
memberikan kontribusi terhadap kecerdasan moral sebesar 47,6 %, hal ini berarti masih
terdapat 52,4 % faktor lain yang dapat mempengaruhi kecerdasan moral

On Coffea Crop (Coffea sp) At North Sumatera. Supervised by
Lisnawita and Lahmuddin Lubis. The research was conducted to determine
biodiversity of plant parasitic nematodes associated with the soil and root of
coffea in Dairi and Simalungun, three locations in Dairi and three locations in
Simalungun. Survey was using random sampling for soil and root and using
corong Baerman modification for plant parasitic extraction at Plant Disease
Laboratory, Plant Pest and Disease Department, Agriculture Faculty, USU from
May to September 2010. Based on this survey two genera of plant parasitic
nematodes where encountered in Dairi and Simalungun.
Plant parasitic nematodes included Radopholus spp and Pratylenchus spp
were most distributed with population densities varying from low to high. The
hightes population densities of Radopholus spp and Pratylenchus spp were found
in Sidiangkat and Bundar Selamat (Dairi) with 34 and 28 juvenile respectively in
soil samples and in the root samples were found in Sidiangkat (Dairi) with 107
and 82 juveniles respectively while the lowest population densities of
Radopholus spp and Pratylenchus spp were found in Merek Raya (Simalungun)
with 12 and 10 juveniles respectively in soil samples and in the root samples were
found in Merek Raya with 25 and 20 juvenile respectively.42 HalamanSkripsi Sarjan

Kab Deli Serdang. This research used technique random sampling non factorial
with 7 treatments and 4 tests.
The result of the test showed that the highest larvhe population was in the
J0 treatment (Control), it was 1,35 and the lowest was in the J6 treatment
(HaNPV Virus, 6g/liter of water), it was 0,1. The average of the crowd population
was in J0 (Control), it was 0,35 and the lowest was in J3 treatment (M. anisopliae
12g/liter of water) and the J6 treatment (HaNPV 6g/liter of water), it was 0. The
highest of intencity percentage was in the J0 (Control), it was 38,75% and the
lowest was in the J6 (HaNPV 6g/liter of water), it was 2,50%. The highest

Efektifitas Penerapan Media Permainan Pantomime Untuk Meningkatkan Kemampuan Berbicara Dalam Kelas Delapan Di Pondok Pesantren Takdibu As Syakiriin Medan Sumatera Utara.
Get PDFJudul ini terbahasa atas dasar keadaan siswa Pesantren Takdibu as syakiriin yang kurang aktif dalam menerapkan berbicara menggunakan bahsa Arab. Karena menurut mereka berbicara bahasa Arab merupakan suatu hal yang sangat sulit untuk dilaksanakan dalam sehari-hari, karena
dalam ruang lingkup mereka yang tidak ada lawan untuk berbicara dengan mereka, sehingga tidak ditemukan keterbiasaan mereka dalam berbicara menggunakan bahasa Arab, serta demikian itu tidak adanya media yang sangat menyenangkan dan membantu dalam pembelajaran bahasa Arab seperti media permainan pantomime karena dengan pembelajaran dengan menggunakan permainan dapat menstransfer ilmu dengan mudah dan dapat mengembangkan
kreatifitas, dan pemikiran siswa, serta dapat mengembangkan pribadi siswa dan aklhakul karikmah siswa.
Perumusan masalah pada penilitian ini adalah pertama, bagaimna kecukupan siswa dalam maharah kalam; kedua , bagaimanakah penerapan media permainan pantomime untuk
meningkatkan kemampuan berbicara; ketiga, bagaimana pengaruh penerapan media permainan pantomimeuntukm meningkatkan kemampuan berbicara. Adapun hipotesis dalam penelitian ini adalah habwasahnya metode Digital Storytelling dapat meningkatkan kemampuan berbicara bahasa Arab. Hal ini tampakm pada hasil yang telah
