Abstract

Pala(Myristica fragrans Houtt) sebagai bioreaktor hayati menghasilkan produk utama minyak asiri bernilai ekonomi tinggi, yang tersebar pada bagian-bagian buahnya. Minyak asiri pala tersusun oleh kelompok besar terpenoid dan fenilpropanoid yang memiliki konsentrasi terkecil namun sebagai indikator mutu minyak pala. Konsentrasi minyak pala dilihat dari keberadaan senyawa penyusun ini telah banyak dilaporkan, namun belum sepenuhnya dijelaskan mengenaimetabolisme fenilpropanoid melalui jalur shikimat yang dihasilkan dari fenilalanin, diawali kondensasi aldol antara eritrosa 4-fosfat dan asam fosfoenolpiruvat dengan melibatkan reaksi enzimatik dikomparasi dari beberapa tanaman penghasil fenilpropanoid dan Arabidopsis thaliana sebagai tanaman model, yang menjadi tinjauan tulisan ini. Regulasi biosintesis pembentukan senyawa golongan fenilpropanoid menjadi penting karena kita dapat diarahkan pada prospek pengembangan senyawa fenilpropanoid dan turunannya secara lebih luas dengan meningkatkan produksinya atau dalam kaitannya dengan menghasilkan obat modern yang bernilai jual tinggi.

Abstract

This study aims to determine the ability of students to identify plant species and to identify the types of plants identified. This type of research is quantitative descriptive with the subject of 29 students of Biology Education Study Program STKIP Soe in the 2018/2019 school year who took the course of Plant Anatomy and Morphology. The research began with the preparation of the instrument, taking students to explore plants in the campus environment and taking specimens identification, then providing identification test questions. Observations were made during student activities. Data processing of test results and observation sheets by counting the total score and converted into a value form then interpreting the value based on the predicate. Based on the results of research students ‘ability to identify plants based on indicators observing the characteristics of plant specimens achieved only students look capable but not maximal so categorized enough and the results of observations of students’ ability to identify plant species in the medium category. The results of identification there are 43 types of plants that are classified into 27 families.

Abstract

Abstrak: Keong mas (Pomacea canaliculata Lamarck) merupakan hama potensial tanaman padi sawah yang berkembangbiak dengan sangat cepat sehingga sulit untuk menekan perkembangannya. Salah satu jenis tanaman yang dapat mengendalikan dan menekan populasi hama ini adalah pinang (Areca catechu L). Penelitian tentang pengaruh pemberian ekstrak pinang terhadap kesintasan telur keong mas, telah dilaksanakan di Laboratorium Biologi Undana Kupang. Tujuan penelitian ini adalah untuk mengetahui: 1) pengaruh pemberian ekstrak biji pinang terhadap kesintasan telur keong mas, (2) nilai LC50 ekstrak biji pinang terhadap mortalitas telur keong mas, (3) nilai LT50­ ekstrak biji pinang terhadap mortalitas telur keong mas. Dalam penelitian ini digunakan rancangan acak lengkap dengan enam perlakuan yang terdiri dari tiga ulangan. Data penelitian dianalisis dengan analisis ragam dan analisis probit untuk menghitung LC50 dan LT50. Hasil penelitian menunjukkan bahwa (1) pemberian ekstrak pinang efektif dalam menghambat dan mematikan telur keong mas serta memberikan pengaruh nyata terhadap kesintasan telur keong mas. (2) nilai LC50 ekstrak pinang adalah pada konsentrasi 18.899% dengan garis regresi Y=10.56 + 1.98x dan (3) nilai LT50 ekstrak pinang yaitu pada 72,980 jam. Pemanfaatan ekstrak pinang sangat direkomendasikan bagi petani padi sawah yang ingin membasmi hama keong mas.Kata Kunci : A. catechu L., Telur P. canaliculata Lamarck, Kesintasan.Abstract: Golden snail (Pomacea canaliculata Lamarck) has been potential pest for rice plant which quickly develops, therefore it is difficult to stop its growth. One kind of plant which is able to stop the growth is areca (areca catechu L.). The influence of giving areca extract toward the development of golden snail’s eggs has already been done by the Biology Laboratory of Undana Kupang. The aim of the study is to know: 1) the influence of areca extract toward the development of golden snail’s eggs; 2) the LC50 value of areca extract on the mortality og golden snail’s eggs; 3) the LT50 value of areca extract on the mortality of golden snail’s eggs. Random technique was used with six sessions of treatment and three tests were implied. The analysis was done by classifying and also probility to count the value of LC50 and LT50­. The result showed that (1) giving areca extract was effective to restrain and stop the development of golden snail’s eggs and giving obvious influence toward the development of the eggs. (2) the value of LC50 areca extract was on the concentration of 18,899% with the regression was Y=10.56 + 1.98x and (3) the value of LT50 areca extract was on 72.980 hours. Therefore, making of areca extract is highly recommended for farmers especially in the rice field who want to prevent the grouth of golden snail.Keywords : A. catechu L., P. canaliculata Lamarck egg, Survivorship.

Abstract

The culture of using plants as traditional medicine by a group of local people is always related to regional identity, rituals, and plant diversity that need to be studied in depth. This study is known as ethnobotany study. This study aims to determine, describe, and analyze the level of ethnobotany knowledge of plants in their use as traditional medicine by the Obesi village community, North Mollo district, South Central Timor district. The methods used were surveys and direct interviews which were guided by a list of questions for several Obesi villagers with the snowball sampling technique. The data obtained were presented in tabulated form and analyzed descriptively with a quantitative approach to determine the ethnobotany level of medicinal plants. The results showed that there were 40 types of plants from 28 families that were used by the community to treat various diseases such as rheumatism, appendicitis, hypertension, fever, convulsions, diarrhea, flatulence, and itching with the most used plant parts, namely leaves, fruit, roots/rhizomes, tubers, midrib, bark, and seeds and flowers in a very simple or traditional way. Ethnobotany level of knowledge based on age class is at a moderate level where the lowest (KU1) 0.574 and the highest (KU4) 0.899, and based on gender, women have a higher level of knowledge than men. The research results are expected to be used as a reference source for important information in the utilization of various types of medicinal plants in the surrounding environment.
