Solid waste of cigarette paper factory does not contain hazard and toxic materials but contain CaCO3 as a lime material. The research of was conducted to study effect of application of solid waste from the cigarette paper factory to improve soil properties at Ultisol Tambunan A. This research was conducted at the Laboratory of Soil Physics, Agriculture Faculty and analytic laboratory of socfindo company from May until June 2016. The research used non factorial completely randomized design consist (CRD) of four (4) treatment solid waste (cigarette paper factory) and five (5) replications, there are: L0 (control), L1 (0,4 g), L2 (0,6 g), and L3 (0.8 g). The results showed that the application of solid waste from cigarette paper significantly increase soil pH, P-available, Ca-exchangeble but not significantly increase K-exchangeable and organic carbon of Ultisol. Application of solid waste from cigarette paper significantly decrease Al-exchangeable and no significantly decrease Al-saturated of Ultisol.

Penelitian ini bertujuan untuk mengetahui keragaan fenotipe progeni kedelai generasi F4 yang dapat tumbuh dan berproduksi tinggi pada tanah salin berdasarkan karakter agronomis. Penelitian ini dilaksanakan di rumah plastik lahan Fakultas Pertanian, Universitas Sumatera Utara, Medan dengan ketinggian tempat ±25 meter di atas permukaan laut pada bulan Februari sampai Juni 2016. Analisis yang digunakan dalam penelitian ini adalah analisis sidik lintas dan uji t pada generasi F4. Parameter yang diamati adalah tinggi tanaman, jumlah cabang, luas daun atas, luas daun tengah, luas daun bawah, umur berbunga, umur panen, jumlah polong, jumlah polong berisi, jumlah polong hampa, bobot biji per tanaman, bobot 100 biji, dan bobot per biji. Hasil menunjukkan bahwa komponen yang memberi pengaruh langsung positif terbesar terhadap produksi biji per tanaman pada kondisi salin adalah jumlah polong dan komponen yang memberikan pengaruh tidak langsung terbesar adalah umur panen. Tanaman yang terpilih berdasarkan produksi bobot per biji tanaman dengan intensitas seleksi 20% terdapat pada 5 nomor tanaman yaitu P2.16.7; P3.28.1; P3.54.6; P3.69.2; dan P6.6.3.

Spodoptera litura is an important pest for tobacco. The objective of this study was to determine the potency of entomopathogenic fungi at various conidia density against Spodoptera litura on tobacco. This study was conducted in screen house, Faculty of Agriculture, University of Sumatera Utara from October until February 2016. This study was used a randomized block design (RBD) with two factors and three replications. The first factor was the conidia density (106, 107, 108 conidia/ml), the second factor was the type of fungi (Metarhizium anisopliae, Beauveria bassiana, and Lecanicillium lecanii) The result showed that: the highest larval mortality was at concentration of 108 conidia/ml (73.33%). The highest larval mortality was on M. anisopliae (57.78%) followed by B. bassiana (51.11%) and L. lecanii (40.00%). The infected larvae showed slow movements, color changes to paleness, decreased appitite, over time silent and die. The dead larva body hardened and blackened. The highest intensity of fungal infection was at concentration of 106 conidia/ml (42.22%). Key words: entomopathogenic fungi, Spodoptera litura, tobacco

The yield of rice crops that have been fertilized intensively by used inorganic fertilizer with high dosecan caused decline of land productivity. The purpose of this research was to know the effect of organicmatter application to increasing organic carbon, P – available, and Zn - available in paddy soil. Thisexperiment was conducted in green house and Laboratory of Research and Technology AgricultureFaculty Univesity of Sumatera Utara, Medan from March until July 2016. Soil samples were takenat Lubuk Dendang village, Serdang Bedagai district. The research used non factorial randomizedcomplete design with eight treatments and three replications, consist of A (control), B (cow manure10 ton/ha), C (rice husk biochar 10 ton/ha), D (straw compost 10 ton/ha), E (cow manure + rice huskbiochar 20 ton/ha), F (cow manure + straw compost 20 ton /ha), G (rice husk biochar + straw compost20 ton/ha), and H (cow manure + rice husk biochar + straw compost 30 ton/ha). Parameters observedare include soil pH, organic carbon, P – available and Zn – available. The result showed that all kindof organic matters and biochar which used in this research have no effect on increasing soil pH, Zn –available but have same effect on increasing organic carbon and P – available.Key words : biochar, organic carbon, organic matters, P – available, Zn -available
