Judul: Pencirian Minyak Sereh Wangi Mahapengiri (Cymbopogon winteranus Jowitt) Klon G1, G2, dan G3 Menggunakan Kromatograf Gas-Spektrometer Massa
Abstrak: Citronellal (Cymbopogon sp) oil is one of the Indonesia's essential oils export commodities. To maintain export quality, in 1989 three types of mahapengiri citronellal (C. winteranus Jowitt) G1, G2, and G3 superior clones were developed. In this experiment, the characteristics of major and minor chemical components within each clone were determined in order to develop formulations of oil fuel bioadditive. The study was started with steam distillation of citronellal leaves of clone G1, G2, and G3. The oil obtained were tested for the physicochemical properties, and the chemical compositions were analyzed with gas chromatograph-mass spectrometer. The results showed that the physicochemical properties of citronellal oil were in accordance with SNI 06-3987-1995. The major chemical constituents of citronellal oil were citronellal, citronellol, geraniol, limonene, β-caryophylene, and citronelyl acetate. The minor chemical constituents included D-germacrene, α-amorphene, endo-1-bourbonanol, geranyl acetate, linalool, δ-cadinene, elemol, β-elemene, (Z, E)-α-farnesene, α-cardinole, and α-humulene.

Judul: A Study on the Withering Effect on the Yield and Quality of Distilled Citronella Oil
Abstrak: Indonesia merupakan salah satu negara penghasil minyak atsiri terbesar di dunia. Minyak atsiri adalah minyak beraroma khas dan bersifat mudah menguap (volatile), contohnya minyak nilam, minyak kenanga, minyak cengkeh, minyak kayu putih, minyak cendana, dan minyak serai wangi. Minyak serai wangi menjadi salah satu minyak atsiri yang menjadi komoditas ekspor unggulan Indonesia. Penelitian ini bertujuan mengkaji pengaruh pelayuan daun serai wangi terhadap rendemen dan mutu minyak serai wangi yang meliputi densitas, indeks bias, kelarutan dalam etanol 80%, warna, dan kandungan total sitronelal geraniol hasil proses penyulingan minyak serai wangi. Bahan yang digunakan adalah daun serai wangi yang diperoleh dari kebun serai wangi milik PT Harmonis Permaculture yang terletak di desa Karacak kecamatan Leuwiliang, sebanyak 3 kg untuk tiap perlakuan. Penelitian ini menggunakan rancangan acak lengkap faktorial dengan dua faktor yaitu lama pelayuan dan lama penyulingan. Perlakuan pelayuan yang diterapkan yaitu dilayukan selama 1, 2, dan 3 hari. Perlakuan lama penyulingan yang digunakan yaitu penyulingan selama 2 dan 4 jam sejak destilat keluar dari kondensor. Hasil penelitian menunjukkan bahwa perlakuan lama pelayuan dan penyulingan berpengaruh nyata (P<0,01) terhadap rendemen dan mutu minyak serai wangi. Hasil uji post-hoc Duncan menunjukkan adanya peningkatan rendemen dan mutu minyak yang signifikan secara statistik seiring dengan bertambahnya waktu pelayuan dan penyulingan. Hasil terbaik diperoleh dari perlakuan pelayuan selama 3 hari dan lama penyulingan 4 jam dengan rendemen 1,14%, densitas 0,891 g/cm3, indeks bias 1,4694, kelarutan dalam etanol 80% 1:2, warna kuning, sitronelal 43,24% dan total geraniol 21,73%. Secara keseluruhan mutu minyak serai wangi yang dihasilkan sudah sesuai SNI 06-3953-1995 untuk kebutuhan ekspor., Indonesia is one of the largest essential oil producing countries in the world. Essential oils are aromatic oils that are volatile, for example patchouli oil, kenanga oil, clove oil, eucalyptus oil, sandalwood oil, and citronella oil. Citronella oil is one of the essential oils which is Indonesia’s leading export commodity. This research aims to examine the effect of withering citronella leaves on the yield and quality of citronella oil which includes density, refractive index, solubility in 80% ethanol, color, and total citronellal geraniol content in the citronella oil as a result of distillation process. The sample used was 3 kg of citronella leaves obtained from PT Harmonis Permaculture located in Karacak village, Leuwiliang district for each treatment. This research used a completely randomized factorial design with two factors, namely duration of withering and distillation. The withering treatment applied was withering for 1, 2 and 3 days. The duration of distillation treatment used was distillation for 2 and 4 hours after the distillate came out from the condenser. The results showed that the duration of withering and distillation treatment had a significant effect (P < 0,01) on the yield and quality of citronella oil. Duncan's post hoc test results showed a statistically significant increase in oil yield and quality along with increasing withering and distillationduration. The best results were obtained from withering treatment for 3 days and distillation time of 4 hours with a yield of 1,14%, density 0,891 g/cm3, refractive index 1,4694, solubility in 80% ethanol 1:2, yellow color, citronellal 43,24% and total geraniol 21,73%. Overall,

Judul: Sikap dan perilaku ibu dalam mendampingi anak menonton televisi (Kasus Desa Bojong, Kecamatan Tenjo, Kabupaten Bogor, Jawa Barat)
Abstrak: Suatu data menyebutkan, anak Indonesia televisi rata-rata lima jam per hari. Tidak hanya program televisi yang menanggapi kebutuhan anak-anak, para pengusaha televisi lebih memusatkan perhatian pada kemampuan menghibur, sehingga banyak tayangan anak yang mengumbar kekerasan, dan pelecehan seksual. Dalam konteks ini, orang tua memegang peranan yang cukup penting. Orang tau harus bersedia membimbing dan memberi tahu soal rambu-rambu dalam menonton televisi. Hal ini perlu dilakukan para orang tua agar anak-anak tidak terpengaruh oleh dampak negatif dari media massa yang terus mengalir lewat teknologi komunikasi yang hanya mempertontonkan hiburan yang tidak bermanfaat.
