Abstract

Genetic diversity of genetic resources is the basic material for producing superior varieties. These genetic resources can be in the form of local varieties, among others. The purpose of this study was to explore the types of local corn in the province of Bali. The method used was a survey method. The primary data collection techniques were observation and interviews and the secondary data in the form of literature study. The types of local corn obtained were then collected. Exploration was carried out at corn planting centres from August 2020 to November 2020. From the exploration results were found 16 local corn types. In Buleleng Regency, four local corn accessions were found, namely: Pangkung Paruk Barak corn, Pangkung Paruk Putih corn, Local Sambirenteng corn and Cicih Kebo corn. In Karangasem Regency, three local corn were found, namely Seraya corn, Purwakerti Putih corn and Ketan Bunutan corn. In Klungkung Regency, one type of local corn was found, Local Nusa Penida corn. In Bangli Regency, six types of local corn were found, namely Kuning Pengootan corn, Local Landih corn, Panes corn/Kuning Daup corn, Injin Daup corn, Bali Malet Gusti corn and Barak Keliki Kintamani corn. In Badung Regency, two types of local corn were found, namely Belok Sidan corn, and Ketan Belok Sidan corn.

Abstract

Bulung boni (Caulerpa sp.) is a type of algae that spreads in almost all Indonesian oceans. Generally, bulung boni grow in shallow water and attach to the sand substrate. This study aimed to determine the bioactive compounds of bulung boni and how they differ from other algae. The identification of bulung boni bioactive compounds was conducted using the GC-MS (Gas Chromatography-Mass Spectrometry) method. Based on the results of GC-MS analysis, bulung boni contains 10 compounds that mainly included into alkane group, i.e. 1-dodecene, Tetradecene, Decene, Pentadecene, Hexadecene, Dodecanol, Haxadecanoic acid, Heptadecene, Oktadecane, and Nanodecene.

Abstract

Effect of Agricultural Waste Types and Em4 Concentration on Nutrition Content of Liquid Organic Fertilizer. Agricultural waste has not been used optimally. This waste can be used as liquid organic fertilizer to get healthy agricultural products and free of pesticide residues. The type of agricultural waste and the concentration of EM4 are factors that play a role in determining the nutrient content of liquid organic fertilizer. The purpose of this study was to obtain the type of agricultural waste, the concentration of EM4, and the best interaction with the nutrient content of liquid organic fertilizer. The research treatment consisted of two factors using a randomized block design. The first factor is the type of agricultural waste consists of three levels, namely (1) vegetable waste + pig waste, (2) vegetable waste + straw + pig waste, and (3) vegetable waste + straw + gamal leaves + pig waste. The second factor is the concentration of EM4 consists of three levels, namely the concentration of 5%, 10% and 15%. The results showed that there was a very significant interaction between types of agricultural waste with EM4 concentration on available P, organic C, pH, and total microbes with the best values of 333.38 ppm (very high), 1.95% (very low), 4.75 (acid), and 19.56 x 106 cfu ml-1. Vegetable waste + straw + gamal leaves + pig waste, and 10% EM4 concentration gave the best effect compared to other treatment combinations on nutrient content. It is recommended that to makes liquid organic fertilizer should use vegetable waste + straw + gamal leaves + pig waste with an EM4 concentration of 10%.
