Abstract

The Ministry of National Education has declared excellence scholarship program, one kind of these excellence scholarships is P3SWOT. P3SWOT is an excellence scholarship given to researcher, writer, creator, artist, journalist, athlete, and figure. As a holder of P3SWOT excellence scholarship, the Secretary of Excellence Scholarship, Bureau Planning and International Cooperation, the Ministry of National Education has been taking the advantage of the information technology by building a website that provides registration information, a registration form that can be downloaded by registrant, and the announcement of the scholarship winners. However, the website is not optimal because it is static. The selection mechanism of P3SWOT excellence scholarship still has some problems. Recently there are ineffective registration and unintegrated scholarship registration data. The online selection of P3SWOT excellence scholarship information system was developed to solve those problems. This information system was developed using Unified Process. Unified Process is an object oriented software development process that consists of five workflows. They are requirement, analysis, design, implementation, and test. This information system was built using PHP 5 programming language and MySQL 5 database management system. This information system can be used to handle the selection of P3SWOT excellence scholarship including registration, registration verification and scoring, deciding the winners, and reporting.

Abstract

Rumput laut ini merupakan sumber komoditi laut yang popular dalam perdagangan dan menjadi sumber pendapatan masyarakat pesisir dan negara. G. verrucosa merupakan salah satu jenis rumput laut yang termasuk komoditi ekspor. Budidaya G. verrucosa masih dipengaruhi oleh faktor lingkungan sehingga pertumbuhannya terhambat dan kualitas panen menurun. Upaya peningkatan produksi dengan hasil pertumbuhan yang baik dilakukan pemberian nutrien. Tujuan Penelitian ini untuk mengetahui pengaruh penambahan pupuk cair dengan konsentrasi yang berbeda terhadap pertumbuhan, kandungan klorofil dan kadar air G. verrucosa. Penelitian ini dilakukan pada bulan Maret - April 2020 dilaksanakan secara eksperimental laboratorium dengan menggunakan metode Rancangan Acak Lengkap (RAL). Berdasarkan hasil penelitian, perlakuan perbedaan konsentrasi penambahan pupuk cair tidak berpengaruh nyata terhadap berat basah G. verrucosa, perlakuan kontrol (tanpa penambahan pupuk) menghasilkan kandungan klorofil paling tinggi dan perlakuan penambahan pupuk cair dengan konsentrasi 6 ml/L menghasilkan kadar air paling tinggi yaitu 46,21 g, penambahan pupuk cair tidak berpengaruh nyata terhadap pertumbuhan, kandungan klorofil dan kadar air G. verrucosa. Seaweeds are a source of marine commodities which is popular in trade and is a source of income for coastal communities and the state. G.verrucosa is one type of seaweed which is an export commodity. G.verrucosa cultivation is still influenced by environmental factors so that growth is stunted and the quality of the harvest decreases. The efforts to increase production with good growth results are carried out by providing nutrients. The purpose of this study was to determine the effect of adding liquid fertilizer with different concentrations on the growth, chlorophyll content and moisture content of G.verrucosa. This research was conducted in March - April 2020 carried out in an experimental laboratory using the Completely Randomized Design (CRD) method. Based on the results of the study, the treatment of different concentrations of addition of liquid fertilizer have no significant effect on the wet weight of G.verrucosa, the control treatment (without the addition of fertilizer) produced the highest chlorophyll content and the addition of liquid fertilizer with a concentration of 6 ml / L produced the highest water content, namely 46,21 g, the addition of liquid fertilizer did not significantly affect the growth, chlorophyll content and moisture content of G.verrucosa.

Abstract

Perairan Pulau Nusa Lembongan merupakan salah satu pulau yang berlokasi di Kab.Klungkung, Bali. Budidaya rumput laut di lokasi ini terdapat beberapa kendala dalam pengembangannya, yaitu keterbatasan pemahaman sumberdaya manusia, modal serta penentuan lokasi busisaya rumput laut. Metode penelitian yang digunakan adalam metode eksploratif dengan pendekatan analisa kuantitatif.Penelitian ini bertujuan menganalisis tingkat kesesuaian lahan budidaya dan mengetahui luasan lahan yang efektif untuk budidaya rumput laut di perairan Pulau Nusa Lembongan. Parameter yang diamati yaitu suhu, salinitas, pH, keterlindungan, kedalaman, kecerahan, arus, substrat dasar perairan, nitrat, fosfat, oksigen terlarut (DO), klorofil-A dan muatan padatan tersuspensi (MPT). Analisis dilakukan dengan pendekatan Sistem Informasi Geografis (SIG). Hasil analisis kesesuaian lahan untuk pengembangan budidaya rumput laut di perairan Pulau Nusa Lembongan yang sangat sesuai sebesar 3.375,65 Ha. Sedangkan luas lahan yang efektif sebesar 2.025,39 Ha yaitu 60% dari luas sangat sesuai dengan jumlah rakit yang dioperasikan sebesar 810.156 unit dan ukuran rakit 1 x25 m serta total produksi pada satu musim panen sebesar 89.117,16 ton/siklus panen.  The waters of Nusa Lembongan Island are one of the islands located in Klungkung Regency, Bali. Seaweed cultivation in this location has several features in its development, namely limited understanding of human resources, capital and determining the location of seaweed busses. The research method used is an exploratory method with a quantitative analysis approach.This study aims to analyze the suitability level of cultivated land and determine the effective land area for seaweed cultivation in Nusa Lembongan Island.
