A polymer monolithic column, poly-(methacrylatoethyltrimethylammonium chloride-covinylbenzyl chloride-co-ethylene dimethacrylate) or poly-(MATE-co-VBC-co-EDMA) was successfully prepared in the current study by one-step thermally initiated in situ polymerization, confined in a steel tubing of 0.5 mm i.d. and 1/16" o.d. The monoliths were prepared from methacrylatoethyltrimethylammonium chloride (MATE) and vinylbenzyl chloride (VBC) as monomer and ethylene dimethacrylate (EDMA) as crosslinker using a binary porogen system of 1-propanol and 1,4-butanediol. The inner wall of steel tubing was pretreated with 3-methacryloxypropyl-trimethoxysilane (MAPS). In order to obtain monolith with adequate column efficiency and low flow resistance, some parameters such as total monomer concentration (%T) and crosslinker concentration (%C) were optimized. The morphology of this monolith was assessed by scanning electron microscopy (SEM). The properties of the monolithic column, such as permeability, binding capacity, and pore size distribution were also characterized in detail. From the results of the characterization of all monolith variation, monolith with %T 30 %C 50 and %T 35 %C 50 give the best characteristic. These monoliths have high permeability, adequate molecular recognition sites (represented with binding capacity value of over 20 mg/mL), and have over 80% flow through pores in their pore structure contribute to low flow resistance. The resulted monolithic columns have promising potential for dual mode liquid chromatography. MATE may contribute for anion-exchange while VBC may responsible for reversed-phase liquid chromatography.

Heavy metals have become a major concern for the community and government. These heavy metals are dangerous substances due on there big effect to human, plants, and farm health. In this research, we focused on Lead (Pb) as the heavy metal sample. Pb ions were absorbed using magnetic nanoparticle Fe3O4 material. Magnetic properties and nanosize of the nanoparticles have been confirmed to absorb heavy metal. Fe3O4 nanoparticle can adsorb Pb heavy metal up to reach 99.98% on concentration mass absorbant variation of 0.56 gram to 0.70 gram.

Telah dilakukan penelitian pembuatan pupuk Organik cair dengan kandungan  Nitrogen cair dengan variasi Penambahan bioaktivator starter dan Promol dan variasi lama, dilakukan variasi lama fermentasi 0, 7, 14, 21 dan 28 hari  .Hasil dari variasi fermentasi kemudian dilakukan analisis nitrogen total menggunakan metode kjeldahl, sampel dilakukan pengulangan sebanyak 3 kali. Hasil analisis nitrogen (N), berdasarkan variasi lama waktu fermentasi dengan dan tanpa menggunakan starter menghasilkan pupuk organik cair organik  pada analisis nitrogen total variasi penggunaan starter kadar optimum terjadi pada hari ke-21 sebesar 29 %, sedangkan menggunakan promol  kadar optimum terjadi pada hari 15 sebesar dan 36 %.

The implementation of community service with the theme of utilizing liquid smoke for odor control in garbage at the Kalibaru Final Disposal Site has been carried out. This service was carried out in three stages, namely counseling, visits to liquid smoke factories and application of liquid smoke to garbage. The results of these activities in general, the community really understands and is able to carry out the processing of waste with liquid smoke independently, but the motivation for entrepreneurship from liquid smoke products has increased at the time of counseling, only 23.3 percent of participants were interested in entrepreneurship, but during a visit at liquid smoke factory even at the time of application all participants were interested in entrepreneurship because of the ease of process and high benefits.   Key words: Liquid Smoke, Garbage, Kalibaru

Telah dilakukan pembuatan TiO2-Plat Kaca untuk fotokatalis dan pengujian aktivitas katalitiknya dalam proses fotodegradasi zat warna Methyl Orange. Pembuatan TiO2-Plat Kaca dilakukan dengan melapiskan larutan TiO2 yang mengandung etanol pada substrat kaca.Struktur kristalnya dianalisis menggunakan difraktometer sinar-X (XRD). Pada penelitian ini analisis difraktometer sinar-X (XRD) dilakukan untuk mengetahui telah terbentuk atau tidaknya fotokatalis. Hasil dari XRD menunjukkan bahwa fotokatalis TiO2-Plat Kaca telah terbentuk dan kristal yang terbentuk ialah anatase. Pengujian aktivitas fotokatalis dilakukan dengan mereaksikan 0,01 gram TiO2 Serbuk serta mereaksikan 2 buah TiO2-Plat Kaca untuk mendegradasi 50 mL larutan Methyl Orange 5 ppm yang disinari oleh sinar matahari sebagai sumber cahaya dengan variasi waktu penyinaran (1/2, 1, 2, 4 dan 6 jam). Dari hasil penyinaran menunjukkan bahwa semakin tinggi waktu penyinaran semakin tinggi % Methyl Orange terdegradasi, dalam penelitian ini efektivitas fotokatalis terbaik adalah pada waktu 4 dan 6 jam.
