Abstract

ABSTRACTGyrinops caudata is one of gaharu plant family Thymeleaceae no less quality than the other speciesin Indonesia. Foliar fertilizers are inorganic fertilizers Gandasil D macro and micro, and a specialpowder for vegetative growth of plants. The purpose of this study was to determine the effect offoliar fertilizers on the growth of seedlings Gandasil D Gyrinops caudata by using completelyrandomized design (CRD) with 4 treatments and 5 replications. Treatment A concentration of 0 g / lof water, the treatment of B concentration of 2 g / l of water, (0.012 g dose), treatment Cconcentration of 4 g / l of water, (0.024 g dose) and treatment D concentration of 6 g / l of water,(dose 0.036 g). The variables measured were plant height increment, diameter increment in thenumber of stems and leaves. The results showed that the application of fertilizer to the seed leavesGandasil D Gyrinops caudata give significantly different results at high accretion, increased stemdiameter and in the number of leaves. Treatment D with a concentration of 6 g / l of water, (0.036 gdose) showed good results in plant growth compared with the other treatments.Key words : Gyrinops caudata, Agarwood, leaf manure Gandasil D

Abstract

ABSTRAKPengolahan tanah intensif yang bertujuan untuk membersihkan gulma dan menciptakan media tumbuh yang gembur pada lahan berlereng menyebabkan tertutupnya pori-pori tanah dan menghambat proses infiltrasi. Proses infiltrasi yang terhambat dapat memicu terjadinya erosi. Pemberian bahan organik (kompos) diharapkan untuk memperbesar kapasitas infiltrasi sehingga dapat mengurangi erosi. Penelitian ini bertujuan untuk mengetahui berapa besar erosi dan infiltrasi yang terjadi pada lahan hortikultura yang berlereng. Penelitian ini dilakukan di lapangan menggunakan metode petak kecil. Hasil penelitian rata-rata erosi yang terjadi pada lahan hortikultura berlereng pada petak teras guludan dengan kompos yaitu 6,54 ton/ha/tahun dan petak guludan tanpa kompos yaitu 4,45 ton/ha/thn. Rata-rata infiltrasi pada lahan hortikultura berlereng dengan perlakuan guludan tanpa kompos lebih tinggi (222552,01 mm/jam) dibandingkan dengan infiltrasi pada lahan hortikultura dengan perlakuan teras guludan dengan kompos (41464 mm/jam).Kata kunci : Erosi, Infiltrasi, Lereng

ABSTRACTInsect parasitoids are small or as large as the host to parasite and off the host. The research was conducted in lowland rice planting area in North Minahasa regency. Research purposes to determine the type and parasitoid populations on rice crop pests in sub Kauditan, Talawaan, and Dimembe. The research was done by sweeping using insect net swing of 20 times on the location of paddy rice crops, sampling is done three times at intervals of two weeks representing all phases of rice growth was identified in the laboratory and then analyzed descriptively. The results showed that the insect parasitoid found was of the Order Hymenoptera and Diptera and in different types and each sub-population, namely, District Kauditan there are 19 types, 19 types Talawaan, and Dimembe13 types. Parasitoids Telenomus spp. average of 6.5 tail in Kauditan, Dimembe 4.5 tail, while the tail Talawaan 3.6 Apanteles sp. average of 6.5 in sub Dimembe tail, Talawaan 6 tails, and tails Kauditan 3.8.Keywords :Parasitoids, Hymenoptera, Diptera, Rice plants

Abstract

ABSTRACT Pineapples are a fruit that grows on bushes with the scientific name Ananas comosus. They are native to Brazil (South America) and have been domesticated there since before Columbus’ advent. In the 16th century, Spaniards brought pineapples to the Philippines and the Malaysian Peninsula, then into Indonesia in the 17th century. This study aims to know the insects associated to monocultured and polycultured pineapples (A. comosus) and to know the dominant insects among said plants. This study is expected to inform about significant insects, both as pests as well as natural enemies, so it can be managed in pineapple planting systems and used in pineapple pest control. This study was done in the pineapple plantation village of Lobong and Mongkunai, regency of BolaangMongondow. Laboratory observations were done in the Weeds and Entomology laboratory of the Agriculture Faculty, University of Sam Ratulangi. Observation of insects on plant pineapples were calculated using the trap sinks. Insect observations showed that there are 6 insect orders founded to monocultured and polycultured pineapple plants, namely: Coleoptera Orders, Orthoptera Orders, Diptera Orders, Hymenoptera Orders, Collembola Orders and Lepidoptera Orders. Dominant insects in the monocultured and polycultured pineapple plantations are firstly from the Hymenoptera Order (Family of Formicidae), next from the Orthoptera Order (Family of Acrididae), third from the Coleoptera Order (Family of Scolytidae) and fourth from the Diptera Order (Familiy of Drosophilidae). Key words : Pineapple Plant (Ananas comosus), Inventory of insects, Monocultured And Polycultured.
