KONTRUKSI KALIMAT SINGKAT BAHASA SUNDA (Kajian Struktur dan Makna Kalimat dalam Majalah Manglẻ)

Penelitian ini bertujuan untuk mengetahui dan mendeskripsikan kalimat singkat dalam majalah Manglé. Dalam penelitian ini digunakan metode deskriptif. Data dikumpulkan melalui teknik studi pustaka dengan instrumen kartu data. Untuk mengolah data digunakan teknik analisis unsur langsung. Hasil penelitian menemkan 706 kalimat singkat yang frekuensi pemakaiannya sebanyak 2028 kalimat. Ditemukan enam tipe kalimat singkat, yakni kalimat salam, kalimat seruan, kalimat panggilan, kalimat judul, kalimat motto, dan kalimat inkripsi. Kalimah singkat memiliki pola tertentu, yakni A : Kal Sal  P + S + K; B : Kal Seru  S + P; C : Kal Pangg  Kata Seru; D : Kal Jud  S + O; E : Kal Mot  FP/FS Koor; F : Kal Ins  FB N + FB Mod. Kalimat singkat mengandung sepuluh makna, yakni rasa syukur, ucapan selamat, seruan pengganti dan nama diri, rasa sakit, marah, menerima, kaget, pernyataan, pedoman, dan cita-cita. This study was to identify and to describe simple sentences in Manglé magazine. This study used a descriptive method. The data were collected through library research technique with data card instrument. The data processing employed direct elemental analysis technique. The research found 706 sentences with the use frequency of 2028 sentences. This study found six types of simple sentences. They are the greetings, appeals, callings, titles, motto, and encryptions. A simple sentence has a certain pattern, namely A : Kal Sal  P + S + K; B : Kal Seru  S + P; C : Kal Pangg  Kata Seru; D : Kal Jud  S + O; E : Kal Mot  FP/FS Koor; F : Kal Ins  FB N + FB Mod. The simple sentence contains ten meanings: gratitude, congratulations, calling for a replacement, and the name of self, pain, anger, acceptance, surprise, statements, guidance, and ideals.

Microwave-Assisted Hydrogenation of Codeine in Aqueous Media

An efficient one-pot microwave-assisted hydrogenation of codeine was achieved in aqueous solution. This technique is simple, fast, environmentally friendly, and highly efficient. Structure of produced dihydrocodeine was approved by using FT-IR, 1H NMR, 13C NMR, EIMS, and elemental analysis technique. Its purity analysis was performed by using HPLC and assay analysis was performed by using potentiometric titration methods.

Preparation, Characterization and Antifoaming Property of Fluorosilicone Oils with Fluoroalkyloxypropyl Group Substitution

The current work has focused on the preparation and property of a novel fluorosilicone oil with polyfluoroalkyloxypropyl group substitution. Using fluoroalcohols as materials, three kinds of fluorosilicone oil, named [3-(2,2,2- trifluoroethyl-oxy)propyl]methylsilicone oil, [3-(2,2,3,3-tetrafluoropropyl-oxy)propyl] methylsilicone oil and [3-(2,2,3,3,4,4,5,5-octafluoropentyl-oxy)propyl]methyl silicone oil, were prepared via condensation, hydrosilylation, cyclization and ringopening polymerization. All the fluoroalkyl derivatives were characterized by NMR, FT-IR, MS and elemental analysis technique. The thermal stability of these fluoroalkyoxypropylmethylsilicone oils was identified to be excellent by thermogravimetric analysis. [3-(2,2,3,3,4,4,5,5-octafluoropentyl-oxy)propyl]methyl silicone oils with different viscosity were prepared by varying the amount of endblock reagent in the polymerization, and the antifoam property of these fluorosilicone oils was investigated. The result showed that the antifoam property of octafluorosilicone oil with higher viscosity was better than that with lower viscosity.
