Abstract

Eco enzyme is a solution of complex organic substances produced by the fermentation of organic waste, sugar and water. Eco enzyme liquid is dark in color and has a strong sour/fresh aroma (Hemalitha and Visantini, 2013). Eco enzyme contains acid and alcohol compounds which act as antimicrobials. The aim of this research was to determine the characteristics of eco enzyme based on five organic wastes, namely eco enzyme made from banana peels, eco enzyme made from lemon peel, eco enzyme made from pineapple peel, eco enzyme made from pieces of spinach stems and leaves, and eco enzyme made from cassava leaves and to know the effectiveness of eco enzyme in the preservation process of tomatoes. The study consisted of 2 research phases, namely quantitatively determining the characteristics of eco enzyme based on five organic materials and determining the effectiveness of the eco enzymeter in the preservation process of tomatoes. of 3.42. The highest total acid was found in the P5 treatment of 5.25%, the highest LAB and yeast populations were found in the P4 treatment, namely 2.34 Log CFU/ml and 2.02 Log CFU/ml. The effectiveness of the five eco enzyme products on the best preservation of tomatoes was found in the P4 treatment, which was 70%. Keywods: Eco Enzyme, Organic Waste, Tomatoes.   Abstrak Eco enzyme merupakan larutan zat organik kompleks yang dihasilkan oleh fermentasi limbah organik, gula dan air. Cairan eco enzyme berwarna gelap dan memiliki aroma asam/segar yang kuat (Hemalitha dan Visantini, 2013). Eco enzyme mengandung senyawa asam dan alkohol yang sangat berperan sebagai antimikroba. Penelitian ini bertujuan untuk mengetahui karakteristik eco enzim berbasis lima limbah organik, yaitu eco enzyme berbahan dasar kulit pisang, eco enzyme berbahan dasar kulit jeruk lemon, eco enzyme berbahan dasar kulit nanas, eco enzyme berbahan dasar potongan batang dan daun bayam, dan eco enzyme berbahan dasar daun singkong serta mengetahui efektifitas eco enzyme terhadap proses pengawetan buah tomat. Penelitian terdiri dari 2 tahap penelitian yaitu, penentuan karakteristik eco enzyme yang berbasis lima bahan organik secara kuantitatif dan penentuan efektifias eco enzyme terhadap proses pengawetan buah tomat. Hasil penelitian menunjukkan karakteristik eco enzyme berbasis lima limbah organik yaitu keasaman (pH) tertinggi terdapat pada perlakuan P2 sebesar 3,42. Total asam tertinggi terdapat pada perlakuan P5 sebesar 5,25%, populasi BAL dan populasi yeast tertinggi terdapat pada perlakuan P4 yaitu 2, 34 Log CFU/ml dan 2,02 Log CFU/ml. Efektifitas lima produk eco enzyme terhadap tingkat keawetan buah tomat terbaik terdapat pada perlakuan P4 yaitu 70 %. Kata Kunci: Eco Enzyme, Limbah Oranik, Buah Tomat.

Abstract

Anoxygenic Photosynthetic Bacteria (APB) has beneficial properties including as probiotic candidates, biofertilizers, bioremediation agents, and can reduce H2S concentrations in waters. However, the APB also has a weakness, slow growth.It is known that the interaction of metal ions and the exposure of magnetic fields increases enzyme activity and growth rates. The aim of this study is to determine the effect of metal ions and the exposure to magnetic fields on APB growth. The APB isolate, AM which is isolated from mangrove roots and tested for its effects on metal ions in seawater complete (SWC) media.The metal ions tested were Cu, Pb, Al and Fe with different concentrations. The metal ion is exposed to a 0.2 mT magnetic field for 10 minutes before being added to the media. The cell count results showed that both metal ions exposed and unexposed to magnetic field did not affect the growth of APB AM isolates. However, the metal ion in SWC media affects the spectra pattern of AM APB isolates.

Abstract

Liwa Botanical Garden (KRL) is an ex-situ plant conservation area which has a large collection of plants. Therefore, there will be many types of plants in KRL that have phytotelmata. Phytotelmata is a plant in which the organs can hold water and is used by various organisms including mosquitoes as natural breeding grounds. The aim of this study was to determine the phytotelmata characteristics and phytotelmata distribution patterns in the Liwa Botanical Garden, West Lampung. This research was carried out in November 2019 - January 2020 at the Liwa Botanical Garden and the University of Lampung Botanical Gardens. The study was conducted descriptively with a survey method approach. The data obtained is displayed in tables and figures. The results showed that there were 7 types of phytotelmata in the Liwa Botanical Garden namely phytothelmata in the plants of Nepenthes mirabilis, Cyathea coopei, Bambusa sp. Areca catechu, Musa sp. Colocasia gigantea, and Crynum asiaticum with 2 phytotelmata distribution patterns: in groups with IP values ranging from 0.813-1,194 and uniform distribution patterns with IP values of -2.08.Keywords: Phytotelmata, Natural Breeding Ground, Kebun Raya Liwa.
