Abstract

AbstrakTelah dilakukan penelitian untuk mengamati kebiasaan makanan ikan gelodok di kawasan mangrove Pantai Meras, Kecamatan Bunaken, Kota Manado, Sulawesi Utara. Kebiasaan makanan ikan gelodok menyangkut jenis-jenis makanan, persentase nilai dari suatu jenis makanan dan nilai bagian terbesar dari komposisi makanannya. Metode yang digunakan di lapangan adalah metode random sampling dengan 30 individu ikan sebagai sampel. Identifikasi jenis-jenis makanan ikan menggunakan mikroskop dengan pembesaran 100x. Hasil analisis dengan menggunakan Indeks Bagian Terbesar didapatkan bahwa makanan utama adalah Crustacea, makanan pelengkap adalah zooplankton, fitoplankton, Polychaeta dan makanan tambahan adalah Hexapoda.Kata kunci : Ikan gelodok, kebiasaan makananAbstractA study to observe the food habit of mudskipper fish in mangrove areas of Meras Beach, Bunaken District, Manado City, and North Sulawesi was conducted. This feeding manner included food types, the percentage value of a particular food and the largest value of food composition. The random sampling method using 30 fish was applied in the site location. The food type of this fish was identified using a microscope with 100x magnification. Results of this research showed that the main food was crustacean, the complementary food was zooplankton, phytoplankton, Polychaeta, and the supplementary food was Hexapoda.Keywords : mudskipper fish, food habits

Abstract

Abstrak   Kupu-kupu merupakan salah satu bagian dari ekosistem yang fungsinya mempertahankan keseimbangan ekosistem dan memperkaya keanekaragaman hayati. Tujuan penelitian yaitu untuk menganalisis kekayaan, kelimpahan, keanekaragaman dan kemerataan spesies di hutan Danowudu, Masarang dan Kawatak, juga membandingkan jenis kupu-kupu berdasarkan topografi pada ketiga lokasi hutan tersebut. Penelitian ini dilaksanakan di hutan Danowudu, Masarang dan Kawatak dan dilanjutkan di laboratorium dari bulan Maret-Juli 2016. Penelitian ini menggunakan metode transek dan rute dibuat sepanjang 1000 m untuk setiap transek. Hasil penelitian menunjukkan bahwa kelimpahan, kekayaan dan keanekaragaman spesies kupu-kupu tertinggi di hutan Danowudu. Kemerataan spesies tertinggi di hutan Masarang. Spesies kupu-kupu yang hanya dapat ditemukan di hutan Danowudu (200-240 mdpl) terdiri dari 13 spesies. Spesies kupu-kupu yang hanya dapat ditemukan di hutan kawatak (827-938 mdpl) terdiri dari 7 spesies. Spesies kupu-kupu yang hanya dapat ditemukan di hutan Masarang (1084-1194 mdpl) terdiri dari 3 spesies. Kata kunci: keanekaragaman, kupu-kupu, Lepidoptera, Sulawesi Utara   Abstract   Butterfly is part of an ecosystem and has function to maintain ecosystem stability and enrich biodiversity. This research aimed to analyze the richness, abundance, diversity and evenness of species in Danowudu, Masarang and Kawatak forest as well as to compare the species of butterflies based on the topography of the three locations of the forest. This research was conducted in Danowudu, Masarang and Kawatak forest and the continued in the laboratory from March to July 2016. This study used a transect method and the route was made as long as 1000 m for each transect. The results showed that the highest abundance, richness and diversity of butterfly species were in Danowudu forest. The highest evenness of species was in the Masarang forest. Butterfly species that was only found in Danowudu forest (200-240 masl) consisted of 13 species. Butterfly species that was only found in Kawatak forest (827-938 masl) included 7 species. Butterfly species that was only found in Masarang forest (1084-1194 masl) comprised 3 species. Keywords: butterfly, diversity, Lepidoptera, North Sulawesi

Abstract

Most of the coconut plantations in Indonesia are dry land, so it is very dependent on rain to meet the water needs of the coconut plants. Changes in rainfall and rainy days affect coconut production. This research was conducted to determine the effect of rainy days and rainfall and its correlation to the production of three varieties of Coconut Tall. The research was conducted at the Mapanget Experimental Garden, IPCRI from January 2019 to April 2019, using data on Coconut Tall Mapanget  Inner Coconut production, rainy day data (days) and rainfall (mm) for the period 2014 - 2020 The analytical method used is multiple linear regression and correlation analysis. The results of multiple regression analysis showed that rainy days and rainfall variables had no significant effect at the 5% test level on the increase in the number of bunches/trees/year, the number of fruits/bunch, and the number of fruits/tree/year in the variety Coconut Tall Mapanget. The results of the regression analysis showed that rainfall and rainy days had no significant effect on the coconut production variables, namely the number of bunches/tree/year, number of fruit/bunch, number of fruit/tree/bunch in KP. Mapanget on plants with a spacing of 9 x 9 m, 5 x 16 m, 5 x 3 x 16 m and 5 x 12 m. The various spacing treatments did not have a significant or significant effect on the coconut production component in coconut tall Mapanget (DMT) but in general, the 9 x 9 m spacing was relatively better than the other spacing treatments.
