Abstract

The demand for maize, the second most important food crop in Indonesia, is steadily increasing. Knowledge of soil properties is a key element in developing nutrient management system. The aims of this study were to characterize and classify the soils at the family level of Soil Taxonomy and linking the taxa with nutrient management systems. The study was conducted at the Site Specific Nutrient Management (SSNM) for maize in Indonesia from June to October 2005. Eight soil profiles were taken from Karo (North Sumatra), Sidomulyo (Lampung), Wonogiri and Grobogan (Central Java), Wonokerto, Mojoayu, and Tuban (East Java), and Jeneponto (South Sulawesi). The soil samples were analyzed for their physical, chemical, and mineralogical characteristics. Soil profile description followed the Standard Guidelines of the Food and Agriculture Organiza-tion. Results showed that the sites for the SSNM represented a wide range of soils and climate characteristics from Entisols with 1,050 mm annual rainfall in Jeneponto to Oxisols with 2,200 mm annual rainfall in Lampung. Most soils had a fine texture class (clay and clay loam), but in places like Lampung and Wonogiri, the clay had a low activity leading to a low cation exchange capacity (CEC) and low exchangeable cations, especially K. The relatively high-K status soils were found in Karo, Grobogan, and Tuban sites. Organic matter and, in consequence, total N were relatively low for all SSNM sites. Available P status ranged from low to high. The low available P in Grobogan, Wonokerto, and Mojoayu soils seemed to be related to high pH, while in Lampung it was due to low pH. Exchangeable Ca and Mg were high in Grobogan, Mojoayu, Karo, and Tuban due to the presence of weatherable minerals such as hypersthene, augite, and hornblende. In general, this study suggests that organic matter, N, and P will be needed across the sites. K addition will be necessary for Karo, Lampung and Wonogiri, while in other SSNM areas, maintenance rates for K will be needed unless plant residues are recycled.

Abstract

Percaya diri menimbulkan rasa optimisme terhadap berbagai macam keadaanyang akan dihadapi. Ketika individu memiliki sikap percaya diri yang rendah akan rentan mengalami rasa pesimisme terhadap sesuatu yang dialami dan cenderung akan menyalahkan orang lain. Hal yang demikian juga dapat terjadi pada peserta didik yang akan menyebabkan motivasi belajarnya menjadi terhambat dan cenderung untuk menempuh segala cara untuk menghindari kegagalan yang akan dialaminya. Tulisan ini mengkaji topik bahasan tentang apakah ada korelasi antara sikap percaya diri dengan motivasi belajar pada siswa SMP Mataram? Metode penelitian ini menggunakan analisis korelasi product moment dan subyek penelitian terdiri dari 35 siswa SMP di Mataram. Dari hasil perhitungan diperoleh nilai hitung dalam penelitian ini adalah 0,9 sedangkan nilai tabel dengan taraf signifikan 5% dan N = 35 adalah 0,334. Berarti hitung tabel (0,911 0,334). Kenyataan ini menunjukkan bahwa nilai korelasi product moment yang diperoleh dalam penelitian ini adalah lebih besar daripada nilai tabel, maka dapat dikatakan bahwa hipotesis nilai (Ho) ditolak yaitu tidak ada korelasi antara kepercayaan diri dengan motivasi belajarpada siswa SMPN di Mataram dan hipotesis alternatif (Ha) diterima. Berarti adakorelasi antara kepercayaan diri dengan motivasi belajar pada siswa SMPN diMataram.

Abstract

Salah satu permasalahan dalam pengembangan vanili adalah kurang tersedia-nya benih dari varietas unggul dan pertumbuh-an yang tidak seragam, akibat penggunaan setek yang tidak seragam. Untuk itu penelitian pengaruh umur fisiologis dan posisi ruas terhadap pertumbuhan bibit dua klon harapan vanili dilaksanakan untuk mendapatkan tek-nologi perbanyakan vegetatif, sebagai landasan penetapan standar prosedur operasional (SPO) perbanyakan benih vanili. Percobaan dilakukan di Rumah Kaca Balai Penelitian Tanaman Obat dan Aromatik (Balittro) dari Januari – Desem-ber 2006, dengan menggunakan klon harapan 1 dan klon harapan 2, yang diambil dari kebun induk vanili di KP Natar, BPTP Lampung. Percobaan faktorial, dengan 2 faktor dan 3 ulangan, disusun dalam rancangan petak terbagi (RPT). Petak utama adalah 2 umur fisiologis sulur, yaitu : (1) 12 bulan dan (2) 6 bulan setelah pemangkasan. Anak petak adalah 10 perlakuan terdiri dari kombinasi 2 klon dan 5 posisi ruas yaitu ; 1). klon 1 + setek dari ruas kesatu; 2). klon 1 + setek dari ruas kedua; 3). klon 1 + setek dari ruas ketiga; 4) klon 1 + setek dari ke empat, dan 5). klon 1 + setek dari ruas ke lima; 6). klon 2 + setek dari ruas kesatu; 7). klon 2 + setek dari ruas kedua; 8). klon 2 + setek dari ruas ketiga; 9). klon 2 + setek dari ke empat, dan 10). klon 2 + setek dari ruas ke lima. Parameter yang diamati meliputi persentase tumbuh benih, tinggi benih, jumlah ruas, dan jumlah daun. Hasil penelitian menunjukkan persentase tumbuh, jumlah ruas, dan jumlah daun tidak nyata dipengaruhi oleh interaksi antara umur fisiologis sulur dan kombinasi klon harapan dengan posisi ruas dan faktor tunggal umur fisiologis sulur, tetapi nyata dipengaruhi oleh faktor tunggal kombinasi klon harapan dengan posisi ruas. Persentase tumbuh tertinggi didapatkan pada perlakuan kombinasi klon harapan 2 dengan posisi ruas kelima (92,92%). Jumlah ruas tertinggi pada perlakuan kombinasi klon harapan 2 dengan posisi ruas ketiga (7,57). Jumlah daun tertinggi didapatkan pada perlakuan kombinasi klon harapan 2 dengan posisi ruas ketiga (7,55). Setek yang berasal dari umur fisiologis 12 dan 6 bulan setelah pemangkasan, serta kombinasi klon harapan 1 dan 2 dengan posisi ruas 1 sampai 5 dapat direkomendasikan sebagai bahan perbanyakan vegetatif tanaman vanili.
