Abstrak: 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. Penelitian tentang isolasi dan identifikasi komponen kimia minyak asiri daging buah dan fuli pala, telah dilaksanakan di Laboratorium CARC UKSW Salatiga dan Laboratorium Terpadu UII Yogyakarta. Penelitian ini bertujuan untuk mengetahui komponen kimia minyak asiri daging buah dan fuli pala berdasarkan tahapan perkembangan buah dan isolasi miristisin sebagai indikator dari kualitas minyak pala. Minyak asiri diperoleh dengan metode ekstraksi kemudian di analisis komponennya menggunakan Kromatografi Gas Spektrometri Massa (GC-MS). Hasil penelitian menunjukkan bahwa komponen kimia terbesar dari minyak asiri daging buah pala secara berturut-turut yaitu tahap pertama miristisin 36.05% pada retensi 11.57 menit, tahap kedua dan keempat α-pinen 39.16%; 34.64% retensi 3.53 menit, tahap ketiga sabinen 33.88% pada retensi 3.99 menit. Sedangkan pada minyak fuli tahap pertama hingga keempat yaitu sabinen 38.72%; 37.51%; 36.24%; 28.93% pada waktu retensi 3.99. Berdasarkan analisis GC-MS menunjukkan bahwa komponen senyawa yang dominan pada daging buah dan fuli yaitu miristisin, sabinen, α-pinen, β-pinen yang berkontribusi bagi aroma khas pada pala. Hasil penelitian diharapkan dapat dimanfaatkan sebagai sumber informasi penting dalam menghasilkan minyak asiri dengan kualitas baik dengan kandungan miristisin terbanyak.Kata Kunci : M. fragrans Houtt; isolasi; daging buah, fuli, minyak asiriAbstract: Nutmeg (Myristica fragrans Houtt) as a natural bioreactor produces the main product that is aetheric oil with a high economic value which is scattered on the parts of the fruit. Aetheric oil consists of a big group of terpenoid and phenylpropanoid which has the smallest concentration but functions as the indicator of nutmeg oil quality. The research about isolation and identification of chemical components of aetheric oil of pulp and mace has been conducted in CARC Laboratory of UKSW Salatiga and Integrated Laboratory of UII Yogyakarta. This current research aims at knowing the components of aetheric oil of nutmeg pulp and mace based on the development stages of the fruit and myristicin isolation as the indicator of the quality of nutmeg oil. Aetheric oil is formed by the extraction method. Then the components are analyzed by using Mass Spectrometry Gass Chromatography (GC-MS). The result of the research shows that respectively the biggest chemical component of aetheric oil consists of the first stage myristicin 36.05% on retention 11.57 minutes, second stage and fourth stage α-pinene 39.16%; 34.64% on retention 3.53 minutes, the third stage sabinene 33.88% on retention 3.99 minutes. Meanwhile on the mace oil, the first to the fourth stage is sabinene 38.72%; 37.51%; 36.24%; 28.93% on retention 3.99. Based on the analysis of GC-MS, it is shown that the most dominant compound components of pulp and mace are myristicin, sabinene, α-pinene, and β-pinene which contribute to the typical scent of nutmeg. The result of the research is expected to be used as an important information source in resulting in aetheric oil with good quality with the most myristicin content.Keywords: Myristica fragrans Houtt; isolation; pulp, mace, aetheric oil

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.

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.
