Abstract

Nipa is one of the vegetation mangroves in Southeast Sulawesi that optimal utilization by people in this region is not optimal because less of information. Attempt to provide information of oil component has done research with the title “Identification of Functional Group of Oil from Nipa Fruit (Nypa fructicans) at Kaliwanggu, Kendari Bay, Southeast Sulawesi”. Research was using the extraction technique, trans-esterification reactions, and FTIR measurements. The extracted oil is having characteristic aromatic, colourless, and volatile. The Oil content was obtain 13.72%, 10.57%, 7.73%, and 3.62% for oil from fiber seed fruit, fruit pulp, fruit cob, and epidermis seed fruit, respectively. The interpretation of FTIR spectrum was obtain vibrations of methylene (CH2) which overlap with vibration of the cis-alkene bond (cis-HC = CH), stretching vibration of ester group (C-O), bending vibrations of C-H, stretching vibration of ester group (C = O), and hydroxyl group (OH). Keywords: Nipa, oil, extraction, trans-esterification, FTIR ABSTRAK Nipa adalah salah satu vegetasi magrove di Sulawesi Tenggara yang pemanfaatannya oleh masyarakat belum optimal karena kurangnya informasi mengenai hal tersebut. Untuk memberikan informasi komponen minyak dilakukan penelitian dengan judul “Identifikasi Gugus Fungsi Minyak Buah Nipa (Nypa fructicans) Kaliwanggu Teluk Kendari Sulawesi Tenggara”. Penelitian dilakukan menggunakan ekstraksi dan reaksi trans-esterifikasi serta pengukuran FTIR. Minyak yang diekstraksi memiliki karakteristik berbau harum dan tidak berwarna (bening) serta mudah menguap (volatil). Kadar minyak diperoleh berturut-turut sebesar 13,72%, 10,57%, 7,73%, dan 3,62% untuk minyak dari bagian sabut, daging buah, tongkol buah, dan kulit ari daging buah nipa. Hasil interpretasi spektrum FTIR diperoleh gugus fungsi yaitu gugus vibrasi gugus methylene (CH2) yang overlap dengan vibrasi ikatan dari cis-alkena (cis-HC=CH), vibrasi ulur gugus (C-O) pada ester, vibrasi tekuk gugus C-H, vibrasi ulur gugus (C=O) dari ester, dan gugus hidroksil (OH). Kata kunci: Nipa, minyak, ekstraksi, trans-esterifikasi, FTIR

Abstract

ZnO is an inorganic material that has many benefits, one of which is in the pharmaceutical field. So far, the synthesis of inorganic materials has been carried out using high temperatures. Research was carried out to synthesize ZnO using hydrothermal at 180°C for 24 hours then burned at temperatures of 300, 600, and 900°C for 6 hours. The compound resulting from synthesis at 180°C was obtained by the compound [Zn(urea)3](NO3)2 which decomposed into ZnO nanoparticle compounds at 300°C to 900°C. ZnO synthesized at temperatures of 300, 600, and 900°C has a hexagonal structure, space group P63/m with lattice parameters a=b= 3.25 Å and c= 5.21 Å and ? = ? = 90° and ? = 120°. The synthesized ZnO has a nanoparticle size in the range of 172-455 nm. Keywords:          ZnO, hydrothermal, synthesis, nanoparticle, hexagonal structure   Abstrak ZnO merupakan material anorganik yang memiliki banyak manfaat, salah satunya dalam bidang farmasi. Selama ini sintesis material anorganik dilakukan menggunakan suhu yang tinggi. Penelitian dilakukan untuk mensintesis material ZnO pada suhu rendah. Metode sintesis material ZnO dilakukan dengan menggunakan hidrotermal pada suhu 180°C selama 24 jam kemudian dibakar pada suhu 300, 600, dan 900°C selama 6 jam. Senyawa hasil sintesis pada 180°C diperoleh senyawa [Zn(urea)3](NO3)2 yang terurai menjadi senyawa nanopartikel ZnO pada 300°C hingga 900°C. ZnO hasil sintesis pada suhu 300, 600, dan 900°C memiliki struktur heksagonal, grup ruang P63/m dengan parameter kisi a=b= 3,25 Å dan c= 5,21 Å serta memiliki sudut ? = ? = 90° dan ? = 120°. ZnO hasil sintesis memiliki ukuran nanopartikel dengan rentang 172-455 nm. Kata Kunci:         ZnO, hidrotermal, sintesis, nanopartikel, struktur heksagonal
