Abstract

ABSTRACT Strawbery is one of the most important fruits commodity in the world, especially for the subtropics countries. Although the strawberry is not a native to Indonesia, but its development which is patterned by the agribussiness and agro-industries can be categorized as one of the income sources  in the agricultural sector. Despite the development of strawberries in Indonesia continues to increase, but when compared with overseas, the strawberry business in Indonesia has not optimally performed. The purposes of this study are to assess and to explain the strawberry crop agri-businesses in the Rurukan Village of East Tomohon District. The results showed that in general, the farming cultivation of strawberry, consisted of: land cultivation, the nursery, and media plant cultivation. It was very important to manage the successful development by the farmers, i.e.: the technique of strawberry planting. Keywords : agribusiness, crop strawberry ABSTRAK Pelaksanaan sistem penempatan yang benar dimaksudkan agar stroberi menjadi salah satu komoditas buah-buahan yang penting di dunia, terutama untuk negara-negara beriklim subtropis. Di Indonesia, walaupun stroberi bukan merupakan tanaman asli Indonesia, namun pengembangan komoditas ini yang berpola agribisnis dan agroindustri dapat dikategorikan sebagai salah satu sumber pendapatan dalam sektor pertanian. Meskipun perkembangan stroberi di Indonesia terus mengalami peningkatan, namun bila dibandingkan dengan luar negeri, usaha stroberi di Indonesia belum dilakukan secara optimal. Tujuan penelitian ini untuk mengkaji serta menjelaskan agribisnis usaha tanaman stroberi di Desa Rurukan Kecamatan Tomohon Timur. Hasil penelitian menunjukkan bahwa usahatani yang dilakukan dalam budidaya tanaman stroberi secara umum meliputi : mengelolah lahan, pembibitan, pengolahan media tanam. Hal yang sangat penting untuk selalu dilakukan petani agar pengembangan tanaman stroberinya berhasil yaitu  teknik penanaman stroberi.

Abstract

ABSTRACT This study aims to determine the effect of plant growth regulators and micro elements to cherelle wilt in cacao plants as well as finding the right business in tackling cherelle wilt in cacao plants. The research was carried out in the garden village folk Eris Eris Minahasa district for 8 months from January to August 2009. Spraying micro-nutrient elements is necessary to reduce cherelle wilt because the various treatments for the first observation is not significantly different, but the observations into two to seven observations to indicate a significant difference between treatments (percentage cherelle wilt on treatment without nutrient elements higher than sprayed). While spraying the treatment factor of plant growth regulators (NAA) is not necessary because the first observation and the two had no significant effect on the percentage of cherelle wilt affected only the third observation and further observations to a fourth, fifth, sixth and seventh again no effect. So is the treatment for fruit length and diameter showed that administration of the micro nutrients necessary for sprayed with micro nutrients result 22.10 cm higher than that is not sprayed is 19.43 cm. As for the diameter of the fruit is affected by plant growth regulators. Treatment is better than 200 ppm 100 ppm and 0 ppm (control). Keywords: NAA, cocoa, mikombi     ABSTRAK   Penelitian ini bertujuan mengetahui pengaruh pemberian zat pengatur tumbuh dan unsur mikro terhadap cherelle wilt pada tanaman kakao serta menemukan usaha yang tepat dalam menanggulangi cherelle wilt pada tanaman kakao. Penelitian ini dilaksanakan di kebun rakyat Desa Eris Kecamatan Eris Kabupaten Minahasa selama 8 bulan sejak Januari – Agustus 2009. Penyemprotan unsur hara mikro perlu dilakukan untuk mengurangi cherelle wilt sebab pada berbagai perlakuan untuk pengamatan pertama tidak berbeda nyata namun pada pengamatan ke dua sampai pengamatan ke tujuh menunjukkan adanya perbedaan nyata antar perlakuan (prosentase cherelle wilt pada perlakuan tanpa unsure hara lebih tinggi dari yang disemprot). Sementara faktor penyemprotan dengan perlakuan zat pengatur tumbuh (NAA) tidak perlu dilakukan sebab pengamatan pertama dan ke dua tidak berpengaruh nyata pada persentase cherelle wilt hanya berpengaruh pada pengamatan ke tiga dan selanjutnya pengamatan ke empat, ke lima, ke enam dan ke tujuh kembali tidak berpengaruh. Begitu juga perlakuan untuk panjang dan diameter buah menunjukkan bahwa pemberian unsur hara mikro perlu dilakukan sebab yang disemprot dengan unsur hara mikro hasilnya 22,10 cm lebih tinggi dari yang tidak disemprot yaitu 19,43 cm. Sementara untuk diameter buah dipengaruhi oleh zat pengatur tumbuh. Perlakuan 200 ppm lebih baik dari 100 ppm dan 0 ppm (kontrol).

ABSTRACT   Rogi, J.E.X. et. al. 2007. The Suistability Land for Corn in the South Minahasa District. Eugenia 13 (3) : 320-326. Based on agri-climate and market prospective, corn is a potential comodity in the South-Minahasa District. From 215.000 ha of South-Minahasa District area, it has 18.437 ha harvest-area and in 2006 produced 52.747 tonnes corn. The above data showed that this district has a possibility to extend the corn planting area in suitable area. To find this suistability area for corn, a spatial data was composed based on soil and climate data using Geographic Information Systemm (GIS). Soil data consisted of texture, pH, C-organic, and cation exchange capacity (CEC), whereas climate data consisted of rainfall and air temperature. Spatial data in the form of land suitability map for corn in the South-Minahasa District was analysed using ArcViewer 3.2. software.   Keywords: Harvest area, soil and climate, spatial data, GIS, ArcViewer 3.2

ABSTRACT Kalangi, J.I. 2005. Growth Analysis of Radish Crop (Raphanus Sativus L) Planted in Various Density. Eugenia 11 (1): 18-24. Plant density is known to be important factor to determine the agronomical target of a maximum production. Plant density is generally determined by spacing. The wide spacing, may caused inefficient farm system. On the contrary, narrow by spaced planting can retard growth. Prediction of growth rates and development of crop plants including radish is insufficient if it is relied only on the change that happens to the crop with days after planting. But the basis of the prediction is its potential production biomass. This research is discover the density that suistable for maximum land - use. This research was conducted in a randomized block design, with five density treatments. The treatments were 40 x 60 cm, 45 x 60 cm, 50 x 60 cm, 55 x 60 cm and 60 x 60 cm each of which is repeated three times. The variable obseverved was crop dry matter. Air temperature and rainfall were also recordee. Data were analysed using ANOVA and SSD for mens differences. Radish growth and produces were determined by growth rate (Cm), periode of linear growth (tm) and period of silent growth (to). Plant density significantly affected the growth of radish. The maximum production was found at 50x60 cm with growth rate6.23g m-2 day-1. Keywords: Raphanus sativus, radish growth

Abstract

ABSTRACT The availability of nutrient inputs for soil fertility in forests is very important to preserve in an effort to anticipate a decrease in land productivity. Litter decomposition is a process of destruction of organic matter (litter) into nutrients available in the soil. This study aims to determine and compare the rate of decomposition of Palaqium obovatum, Spathodea campanulata, and Calophyllum soulattri litter in Bron Warembungan Forest, Minahasa Regency. This study was carried out on the leaf litter of Palaqium obovatum, Spathodea campanulata, and Calophyllum soulattri. The method of decomposition rate data collection using 36 litter bags placed randomly (with experiments using a completely randomized design (CRD) with two factors namely tree type and duration of decomposition) on the forest floor taken every week for four weeks, followed simultaneously with temperature measurements and humidity. The results showed that of the three main tree species in Bron Forest, the highest decomposition rate was shown by leaf litter of Spathodea campanulata with an average of 15.49% per week, followed by Palaquium obovatum (11.74% per week) and then Calophyllum soulattri ( 3.07% per week). The decomposition process in the three leaf litter took place very quickly in the first week which can also be associated with the results of measurements of water content in litter.Keywords: tropical rainforest, decomposition of litter, leaf litter

Abstract

ABSTRACT The problem in postharvest pests must be handled seriously since recent research were not comprehensively resolved it. Sitophilus oryzae was a major pest and serious problem on post harvest products. The reseach aimed  to develop a life table of S. oryzae on rice. The life table is a part of life history that consists of important information about the living organism. This information can be used for predicting population growth. By developing life table database, information on mortality, life expectancy, and the development ability of S. oryzae can be obtained. Results showed that mortality index of eggs was 0.4;  larvae was 0,54, and pupae was 0,32, and adult was 1,0. Life expectancy index of eggs was 1.65; larvae was 1.42; pupae was 1.51 pupae; and adults was 1.0. One female was able to give rise 32.56 females or 58.57 males and females of the next generation. Keywords : Life table, Sitophilus oryzae,  mortality index,  life expectancy
