Development of food preservation with the use of liquid smoke technology continues to be done in order to produce a product that has the taste of smoke, durable and safe for consumption. To make easy handling and application redistilat liquid smoke, an innovative technology in making smoke powder has developed using maltodextrin as the medium carrier. The method in the process of drying the product was drying with spray dryer with the end result in the form of powder and the most widely used in industry, especially the food industry. The purpose of this study was to determine the process of making liquid smoke powder by spray drying method and see its effect on the flavor and shelf life of sauce. The main tool used is a spray dryer and mixer. The main material used is liquid smoke and dextrin. Optimal conditions of liquid smoke powder procesing is at concentration 5% and temperature inlet 160°°°°C. Concentration and inlet temperature very significant effect on the moisture content, bulk density and yield. Concentration did not significantly affectt the solubility. Giving liquid smoke powder increase the shelf life of sauce is 7 days. Providing optimum flavor can still be received by respondents is at the level 2%.

Potensi ikan yang ada di Kecamatan Koto XI Tarusan Kabupaten Pesisir selatan terbilang cukup besar yaitu sebesar 140 ribu ton pertahun. Teknik pengawetan ikan diperlukan untuk memperpanjang masa simpan dan mempertahankan mutu kesegaran ikan. Penggunaan asap cair untuk mengawetkan ikan diharapkan menjadi solusi penggunaan pengawet yang berbahaya selain itu kelebihan penggunaan asap cair mudah, aman dikonsumsi dan efektif jika digunakan sesuai kadar yang telah ditentukan. Nelayan di daerah ini masih kurang memahami tentang teknis pengawetan ikan dengan menggunakan asap cair. Asap cair dapat dimanfaatkan dalam berbagai bidang industri seperti industri pangan sebagai pengawet dan flavour, dalam industri perkebunan maupun industri perkayuan. Program pelatihan ini diharapkan dapat memberikan pemahaman kepada masyarakat khusunya nelayan tentang teknis pengawetan ikan dengan menggunakan asap cair sehingga dapat menjaga kesegaran ikan lebih lama dan meningkatkan perekonomian. Metode pelaksanaan kegiatan ini dilakukan dengan cara demontrasi atau peragaan teknis penggunaan asap cair sebagai pengawet ikan yang dilakukan oleh instruktur (dosen) yang diikuti praktek dari peserta. Target dan luaran yang ingin dicapai adalah nelayan mampu mengaplikasikan pengawetan ikan dengan menggunakan asap cair. Masyarakat dapat menghasilkan ikan (produk olahan ikan) menggunakan pengawet asap cair. Hasil dari kegiatan ini adalah menigkatnya pemahaman nelayan sebesar 85% tentang pengetahuan asap cair dan seluruh nelayan (100%) mempu mempraktikkan dan mengaplikasikan asap cair dalam upaya mengawetkan ikan.

The use of palm oil mill fly ash (FA) as a low-cost adsorbent is one of the solutions for handling FA waste. In this study, the addition of dolomite is expected to improve the adsorbent performance. The aim of this study was to investigate the optimum FA-dolomite adsorbent composition and operating conditions for methylene blue adsorption. Different parameters were studied to optimize adsorption process such as the amount of dolomite, methylene blue flow rate, bed height and number of trays. FA-dolomite was converted into nano-adsorbent by sol-gel method which was coated on zeolite surface. Nano-adsorbents were characterized by XRF, FTIR, XRD and SEM. The adsorption capacity was tested by Spectrophotometer UV-Vis. XRF characterization showed that FA had the highest SiO2 content of 58.15%, while dolomite contained CaO of 52.72%. FTIR characterization detected the groups of Si-O-Si, Si-O-Al, Ca-O and Si-O. XRD characterization showed the average crystalline size of FA-dolomite 2% adsorbent was 28.56 nm and SEM characterization showed fine pores on the adsorbent surface. The highest adsorption efficiency obtained at FA-dolomite 2% was 97.364% and the lowest obtained at FA-dolomite 8% was 13.16% with a flow rate of 500 ml/h, adsorbent height of 9 cm and 3 trays. The greater the amount of dolomite added, the absorption efficiency decreases.
