Abstract

The objective of the research was to determine the grazing pressure in mix pasture of signal grass (Brachiaria decumbens) and puero (Pueraria phaseoloides) at coal mining reclamation. The experiment was arranged by randomized block design consisted of 5 stocking rate treatments, those were 12.56, 19.63, 28.26, 38.47, and 50.24 m2.animal-1.d-1 which were equal to length of tether rope of 2.0, 2.5, 3.0, 3.5, and 4.0 m, respectively. The rotation system was applied by modifying the tether. Each rotation period was 30 d of three-rotation period. Result of this experiment showed that average daily gain (ADG) was different (P

Abstract

Abstrak: Tujuan penelitian ini secara umum untuk mendapatkan informasi yang akurat untuk meningkatkan aktivitas belajar siawa dalam pembelajaran matematika di kelas VI Sekolah Dasar Negeri 10 Mendawa Lidah Kabupaten Kayong Utara. Metode yang digunakan adalah metode deskriptif . Terdapat peningkatan aktivitas fisik mulai dari siklus I sampai siklus II yaitu dari 65% meningkat menjadi 80%. Peningkatan aktivitas mental mulai dari siklus I sampai siklus II yaitu dari 65% meningkat menjadi 75%. Peningkatan aktivitas emosional mulai dari siklus I sampai siklus II yaitu dari 63% meningkat menjadi 80%. Dengan demikian skor rata-rata aktivitas belajar siswa pada siklus I dikategorikan baik, kemudian skor rata-rata aktivitas belajar siswa pada siklus II dikategorikan sangat baik.   Kata Kunci: Aktivitas Belajar, Teknik Think-Pair-Share. Absrtact: The purpose of the research is to get real information to improve student activity learning in mathematic learning in sixth grade of Sekolah Dasar Negeri 10 Mendawa Lidah Kabupaten Kayong Utara. The method of this reseach is descriptive. There are increasing of physic activity from cycle I is 65,00% to be 80,00% in cycle II. There are increasing mental activity in cycle I it is 65,00% to be 75,00% in cycle II. There are increasing in emotional activity in cycle I it is 63,00% to be 80,00% in cycle II. The average score of student activity learning from cycle I is good, then the average score of student activity learning in cycle II is very good.   Keyword: Learning Activity, Think-Pair-Share Technique

Abstract

 This study was aimed to analysis abundance and species diversity of predatory insects and parasitoid of Aphis gossypii from lowland and highland areas of South Sumatra.    Survey of was conducted in 11 vegetable centers of  South Sumatra.  The results showed that 20 species of predatory insects and 3 species of parasitoids were found from the survey. The predatory insects consisted of 15 species of coccinellid beetles, two species of syrphids, and  one species of chamaemyiid, mantid and staphylinid.  Parasitoid found were 2 species of Aphidiidae (Diaretiella rapae and Aphidius sp.) and a species of Aphelinidae (Aphelinus sp.).  The highest abundance of the predator was found in Soak (42.61 larvae and adults) and the highest abundance of the parasitoid was found in Talang Buruk (25.99 adults).  The highest species diversity of the predator and the parasitoid were found in Soak (15 species and H’= 0.94) and in Talang Buruk (2 species and H’ = 0.27), respectively.  Abundance and species diversity of the predators and parasitoids were higher in the dry season than those in rainy season. Thus, the abundance and species diversity of the predators and parasiotids were higher in the lowland than highland areas in South Sumatra, while the seasons affected the abundance and species diversity of the predators and parasitoids.

Abstract

Penelitian ini bertujuan untuk (1) menganalisis kinerja dan efisiensi dari industri batik di Kota Pekalongan sebelum dan setelah pelaksanaan Asean China Free Trade Agreement (ACFTA) dan (2) menganalisis faktor yang mempengaruhi efisiensi industri batik di Kota Pekalongan. Penelitian ini menggunakan analisis statistik inferensi untuk menguji perbedaan kinerja dan efisiensi industri batik di Kota Pekalongan sebelum dan setelah pelaksanaan ACFTA. Pendekatan stochastic frontier digunakan untuk menghitung tingkat efisiensi dan analisis multiple regression digunakan untuk menganalisis faktor yang mempengaruhi efisiensi industri batik. Penelitian ini menemukan bahwa setelah pelaksanaan ACFTA, maka (1) profit margin industri batik di Kota Pekalongan turun secara signifikan, (2) efisiensi teknis industri batik di Kota Pekalongan terus melonjak tajam hingga 84 persen (sebelum pelaksanaan ACFTA) menjadi 88 persen, dan (3) faktor yang mempengaruhi efisiensi dari industri batik di Kota Pekalongan adalah paguyuban (mewakili modal sosial), pendidikan (mewakili kualitas sumber daya manusia), dan penggunaan teknologi blower.

The objective of the research was to determine the grazing pressure in mix pasture of signal grass (Brachiaria decumbens) and puero (Pueraria phaseoloides) at coal mining reclamation. The experiment was arranged by randomized block design consisted of 5 stocking rate treatments, those were 12.56, 19.63, 28.26, 38.47, and 50.24 m2.animal-1.d-1 which were equal to length of tether rope of 2.0, 2.5, 3.0, 3.5, and 4.0 m, respectively. The rotation system was applied by modifying the tether. Each rotation period was 30 d of three-rotation period. Result of this experiment showed that average daily gain (ADG) was different (P2.animal-1.d-1 and decreased linearly with increasing length of rope from 254.29 to 100.17 kg.ha-1. Maximum dry matter consumption was achieved at length of tether rope of 3.32 m or grazing area 34.61 m2.animal-1.d-1. Average dry matter yield in this experiment was 235.39 g.m-2.d-1 or 2.35 ton.ha-1.mo-1. Botanical composition of signal grass, puero, and weeds before and after grazing was change with grazing pressure.
