Abstract

ABSTRACTThe type of soil in the research site is Andisol soil with clay texture. The Andisol soil characteristics is a dark color / black, gray, dark brown to yellowish. The soil derived from volcanic ashes from the eruption of the volcano. Therefore, this type of soil are found in the area around the volcano's slopes. Like the soil in this research is located on the slopes of Mount Mahawu. Although it has many advantages, but the ground Andisol also has many disadvantages. Andisol ground weakness is due to the loose structure and crumbly, the type of soil is very easy take by rainwater. Therefore, in this research, land conservation efforts in the form of plastic mulching. In this study the use of plastic mulch as a treatment, more soil erosion results in the use of plastic mulch plots compared to not using plastic mulch. This is due to the use of plastic mulch, most of the rain water does not infiltrated into the ground because it was blocked by the plastic mulch, causing greater runoff. Large land runoff causes soil erosion more bigger easily transported.Keywords : Erosion, Soil Conservation Technique, Holticulture, Carrot (Daucus carrota L.)

Abstract

ABSTRACTPotato (Solanum tuberosum L.) is one of the important vegetable commodities that have great potential to support food diversification program. . Besides the development of the snack industry and fast food restaurants are one of the raw material is potato thus increasing the demand for potato products both in quantity and quality that is safe for consumption. This study aims to determine the population growth miridae (Nesidiocoris tenuis and Lygus sp) on potato in Linelean Village District Modoinding. The research took place for two months from May to July 2012. Observations development of populations miridae (N. tenuis and Lygus sp.) Executed directly on the potato crop by counting the number of individuals per plant nymph and imago. Observations were carried out 5 times since 3 weeks old plants at intervals of 2 weeks is 3 (wap), 5 (wap), 7 (wap), 9 (wap), and 11 (wap). Each observation was observed 20 samples with random sampling method. The results showed the populations N. tenuis is found only on the observations I 3 (wap) and observation II 5(wap) with the average population of the observations I: 0,50 individuals and observations II: 0,80 individuals. While the populations Lygus sp. found in the observations I 3 (wap) to IV 9 (wap) with the average population of the observations I: 0.65 individuals, observations II: 1.10 individuals, observations III: 1.70 individuals, and observations IV: 1.40 individuals . Symptoms of N. tenuis is on the trunk and branches of the potato crop stylet puncture marks that are yellowish. While symptoms of Lygus sp. attack will not immediately apparent but will be visible after the leaves begin to open and enlarge.Keywords : Potato, Nesidiocoris tenuis, Lygus sp

Abstract

ABSTRACTPaddy is the most important staple food in Indonesia, since more than half of the population is dependent on the rice that the paddy plants produce. About 1,75 billion of the three billion Asians, including 210 million Indonesians rely on rice as their primary source of calories. The object of this research is to know the population density and infestation intensity of the paddy bug L. acuta on paddy plants in the North Tombatu, East Tombatu and Pasan Districts of the South-east Minahasa Regency. This research is expected to inform about the population density and infestation intensity of the paddy bug L. acuta in several different places and attempts in controlling it. Results of this research show that the paddy bug has spread in paddy fields over the three districts. The highest population was found in the district of East Tombatu (33,9 individuals / ten double sweeps), followed by the Pasan District (24,1 individuals / ten double sweeps), while the district of North Tombatu had the lowest population (9,2 individuals / ten double sweeps). The high paddy bug population is influenced by environmental factors and farmers’ habits in breeding field paddy plants. The intensity of the paddy bug infestation is already high, so the presence of this pest is highly worrisome.Key words : paddy plants, population density and infestation intensity, paddy bug pest (Leptocorisa acuta Thunb.)

Abstract

ABSTRACTThe morphological and behavioral characters indicate the identity of the type or species of insects and closely related to the selection and determination of the type of insect food. This study aimed to see differences in morphological characters Necrobia spp. on some kinds of deposits. It is hoped this research can provide information on morphological characters Necrobia spp. on some kinds of deposits. This study uses survey methods, and sampling was done by "purposive sampling" is intentionally sampling by selecting and determining the sampling site. The results showed that the morphological Necrobia spp. imago on copra, dried shrimp and fish rowa there is a difference. Morphological differences Necrobia spp. imago views of body size, body color, male and female differences. Dense population Necrobia spp. imago the highest in the kopra 33.25 individu/500gr, dried shrimp followed the 31.5 individu/500 gr, then the fish rowa 27.25 individu/500gr while the peanuts are not found Necrobia spp.

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

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.
