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.

Abstract

Cabai merah besar (Capsicum annuum L.) merupakan salah satu tanaman hortikultura yang memiliki banyak manfaat. Peran dan manfaatnya tersebut menjadikannya sebagai salah satu komoditas hortikultura dengan tingkat produktivitas yang tinggi. Produksi cabai merah besar (C. annuum L.) cenderung terus menurun dan salah satu penyebabnya yaitu gulma. Gulma yang biasa hidup berdampingan dengan tanaman hortikultura ialah rumput teki (Cyperus rotundus L.). Rumput teki mengandung senyawa alelokimia yang akan mempengaruhi tanaman disekitarnya. Senyawa alelokimia tersebut dapat memacu sekaligus menghambat pertumbuhan tanaman. Oleh karena itu dilakukan uji perendaman benih C. annuum L. di dalam ekstrak etanol daun C. rutundus L. untuk mengetahui pengaruhnya terhadap pertumbuhan C.annuum L. Penelitian ini dilakukan menggunakan Rancangan Acak Lengkap (RAL) dengan ekstrak etanol daun rumput teki (C. rotundus L.)  dalam 6 taraf konsentrasi (0%, 5%, 10%, 15%, 20%, dan 25%) dengan 4 kali pengulangan.  Parameter yang diamati yaitu persentase perkecambahan, tinggi tanaman, jumlah daun, panjang akar, berat basah tanaman, berat kering tanaman, kandungan klorofil dan skor keracunan. Data yang diperoleh dianalisis dengan ANOVA dan dilanjutkan uji lanjut Beda Nyata Jujur (BNJ) dengan taraf 5 % (α= 5 %). Hasil penelitian menunjukkan bahwa ekstrak rumput teki pada konsentrasi 5% dapat memacu pertumbuhan jumlah daun, menghasilkan jumlah berat basah dan berat kering terbesar pada tanaman cabai merah besar, sedangkan konsentrasi 25% dapat menghambat proses perkecambahan, menekan pertumbuhan tinggi tanaman, menekan jumlah kandungan klorofil dan menyebabkan keracunan pada daun.

Abstract

Infectious diseases are a significant public health issue in both developed and developing countries. Infectious diseases are caused by the bacteria Staphylococcus aureus and Escherichia coli, which cause high rates of morbidity and mortality. Treatment of infectious diseases caused by pathogenic bacteria generally uses antibiotics, but the continuous use of antibiotics can have side effects such as the occurrence of antibiotic resistance.  Diplazium esculentum is one of the medicinal plants that is often used to treat infectious diseases.  The content of secondary metabolite compounds contained in D. esculentum includes saponins, steroids, alkaloids, tannins, glycosides, triterpenoids, phenols, flavones, and flavonoids.  This study aims to determine the effect of bacteriostatic activity of ethanol extract of D. esculentum and its effective concentration in inhibiting the growth of pathogens S. aureus and E. coli.  The study was conducted using a Randomised Complete Block Design (RAKL) with four concentrations of ethanol extract of vegetable fern, namely 20%, 33%, 43%, and 50%.  As a positive control, the antibiotic chloramphenicol was used and the negative control used sterile distilled water.  Data in the form of inhibition zone diameter formed from each treatment were analysed using Kruskal Wallis non-parametric test and continued with Mann Whitney Post Hoc test.  The results of the study showed that the concentration of ethanol extract of D. esculentum showed bacteriostatic activity against S. aureus bacteria at concentrations of 43% and 50% with inhibition zones of 6.52 mm and 5.55 mm, as well as E. coli bacteria at concentrations of 43% and 50% with inhibition zones of 5.11 mm and 4.37 mm, but was not effective in inhibiting the growth of S. aureus and E. coli bacteria.
