KETAHANAN ENAM KLON KARET TERHADAP INFEKSI  CORYNESPORA CASSIICOLA PENYEBAB PENYAKIT GUGUR DAUN

Resistance of six rubber clones to Corynespora cassiicola the pathogen of rubber leaf fall disease. The objectives of the research was to evaluate the resistance of six rubber clones to Corynespora cassiicola, the pathogen of rubber leaf fall disease. The research was conducted at Phytophatology laboratorium and green house at the Plant Pest and Diseases Department, Faculty of Agriculture, Sriwijaya University, from March to July 2008. The treatments were arranged in a completely randomized block design (CRBD) with six treatments and four replications. Each replication consisted of four polibags of rubber plants. The clons tested were GT 1, PB 260, IRR 39, BPM 1, BPM 24 and PR 261. The results showed that IRR 39 was the most susceptible clon to C. cassiicola infection, whereas disease severety reach up to 98.45 % and leaf fall 73.95 %. Clon PB 260 show as the moderat resistance clon to the pathogen infection. The severity disease of this clon only 41.53 % and leaf fall 10.41%.

ABSTRACTThe ability of Bacillus subtilis and Lysinibacillus sp. singly or mixed, with carbon fiber and nano silica to induce resistance of shallot to purple blotchPurple blotch disease caused by Alternaria porri is one of the major disease on shallot. One of the methods that can be applied to control the disease is the use of antagonistic bacteria. Antagonistic bacteria can be used as a resistance inducer to suppress pathogen development. In this study, Bacillus subtilis and Lysinibacillus sp. were formulated in carbon fiber as a carrier and nano silica 3% as a complementary. This study was conducted to determine the ability of Bacillus subtilis and Lysinibacillus sp. singly or mixed, with carbon fiber and nano silica to induce resistance of shallot to purple blotch. The experiment was conducted at the Laboratory of Phytopathology, Departement of Plant Pest and Diseases and Ciparanje Green House, Faculty of Agriculture, Universitas Padjadjaran from December 2017 until July 2018. Suspension of Bacillus subtilis and Lysinibacillus sp. singly or mixed were formulated in carbon fiber 80 Mesh and 3% nano silica. The experiment used Randomized Block Design consisted of 8 treatments with 3 replications. Each replication consisted of 5 plants. The results showed that the mixture of Bacillus subtilis and Lysinibacillus sp. in 3% silica nano and carbon fiber was the ablest treatment to increase the resistance of shallot to purple blotch by 71,2%.Keywords: Antagonistic bacteria, BiocontrolABSTRAKPenyakit bercak ungu yang disebabkan oleh Alternaria porri merupakan salah satu penyakit utama pada bawang merah.

The purpose of this research was to determine the effect of addition of Multinutrient Sauce (MNS) in the ration on digestibility of crude protein and crude fiber in sheep. This research was conducted in May—July 2019 at the People's Farm of Kebagusan Village, Gedong Tataan District, Pesawaran Regency. The digestibility analysis of crude protein and crude fiber was carried out at the Laboratory of Animal Nutrition and Feed, Animal Husbandry Department, Faculty of Agriculture, University of Lampung. This study used a randomized block design (RBD) based on sheep body weight with six groups and three treatments, namely R0 (ration without MNS); R1 (R0 + MNS 5%); and R2 (R0 + MNS 10%). The data obtained were analyzed using ANOVA at a 5% significance level or 1% significance, and continued with further test using Least Significant Difference Test (LSD) if there is significant results. The results showed that the addition of 10% MNS in the ration had a significant effect (P<0.05) on increasing the digestibility of crude protein and crude fiber in sheep. Keywords: multi nutrient sauce (MNS), digestibility of crude protein, digestibility of crude fiber, sheep.

Utilization of maize waste as the organic matter sources in agricultural land couldn’t be directly applied, caused by late decomposition prosess. An effort to accelerate of maize waste decomposting needed bioactivator. The research was conducted in green house and Bajeng Research Intallation from March to August 2015. The research was arranged in randomized block design using isolate bacteria and fungus just one or theier combining ie: three bacteria (B7.1,E7.7and E7.11), three fungus (M7, O5, P7), and four bacteria-fungus combining(B7.1+O5, B7.1+M7, E7.7+P7, B7.1+E7.7+O5), EM4 and N,P,K fertilizer(200,45,60) ha-1as the check treatment. Just one isolate fertilized by 75 percent N,P,K while combine isolate fertilized by 50 percent N,P,K recommended. The results indicated that just one decomposer E7.7 produced high enouugh grain yield not siqnificantly different by N,P,K (200,45,60) and five other just one treatment (E7.11,B7.1,M7 and O5), however siqnificantly different with combining decomposer (B7.1+O5, E7.11+M7, E7.7+P7, B7.1+E7.7+O5 and EM4). This mean that using stalk plus leaf waste maize compost could be subtitution in organic fertilizer untill 25 percent. Meanwhile combining decomposer was good enough for composting stalk and leaf of maize waste ie. isolate B7.1+O5 and E7.7+P7 although not significntly different with the other combine isolate including EM4. Thise case related by applied 50 percent N,P,K inorganic recommended fertilizer did not sufficient to supporting maize nutrient.Key Words: Decomposer, Bacteria, Fungus, Composting,Maize waste

There is few people who like goat milk, that is why process of making goat milk into ice cream is needed. Therefore, a research has been done at Animal Production Laboratory of Husbandry Department, Faculty of Agriculture, University of North Sumatera, from April to May 2018. The design which used in this research is Randomized block design (RAK) with two factors: kefir concentration (P): (0%, 10%, 20%, 30%) and aging time (L): (6, 12, 18, 24 hours). Parameters which observed were overrun, melting time and organoleptic test (color, aroma, texture, taste). The results showed that the interaction between kefir concentration and aging time gave a significant effect to organoleptic result of flavor and did not give significant effect to overrun, melting time and organoleptic results (color, texture, taste). The concentration of kefir had given significant effect to melting time and organoleptic results (color, aroma, texture, taste) and did not give significant effect to overrun result. The aging time gave a significant effect to overrun, melting time and organoleptic results (color, aroma, texture), and did not give a significant effect on organoleptic taste result. The best result was obtained in addition of kefir extract of red dragon fruit 30% with aging time aged 6 hours on ice cream made of goat milk.

ABSTRACT The experiment was conducted in the village of Touure, Tompaso District, Minahasa regency since April to August 2013. Designed studies using randomized block design with 3 treatments, namely fruit extract Bitung (treatment A), tuba root extract (treatment B) and water (control treatment), each treatment was repeated 3 times. Results showed that that the extract of Barringtonia asiatica and Derris elliptica has a botanical insecticide to control the properties of N. tenuis. Applications B. asiatica extract and D. elliptica were not significantly different, but both are significantly different from controls. In addition to N. tenuis found several Plant Pest Organisms (OPT) that attack tomato plants including pest Liriomyza sp., leafhoppers tomatoes., black stem base diseases, leaf spot diseases and viral diseases. Key words : Botanic Insecticide, Tomato pest control ABSTRAK Penelitian dilaksanakan di Desa Toure, Kecamatan Tompaso, Kabupaten Minahasa sejak bulan April sampai dengan Agustus 2013.

Asystasia gangetica is one of the plantation weeds that grows under shading area and has potential use as forage. The aim of this experiment was to analyze the cutting stem of A. gangetica regrowth that immersed on growth promotor hormone under different plant shadding. The treatments were arranged A. gangetica plant in a Completely Randomized Block design that consisted of 2 hormone (auxin and cytokinin) and 5 shading (green house, open space, under Indigofera zollingeriana tree, under Bauhinia sp and Glyricidia sepium). The results showed that residual hormones have small effect on the number of A. gangetica primary branches only. Shading environment increased A. gangetica regrowth, especially on plant height, number of branches and ϐlower development, except Bauhinia shading. It concluded that A. gangetica has potential to develop as ruminant forage due to high regrowth capability.
