Abstract

Banyak kejadian kebakaran hutan menyebabkan gangguan yang cukup nyata karena lokasi titik api yang tidak dapat diketahui dengan cepat. Kesulitan dalam menentukan titik api terletak pada lokasi yang sulit dideteksi dan gangguan asap yang timbul dari kebakaran tersebut. Hal ini menyebabkan pemadam kebakaran hutan sulit sekali mendeteksi lokasi titik api, sehingga tindakan pencegahan tidak dapat dilakukan secara dini. Dengan pengolahan citra digital menggunakan pendekatan pengolahan warna gambar yang dapat memberikan lokasi titik api sehingga analisis dan tindakan dapat dilakukan dengan cepat dan akurat. Dengan deteksi dini yang dilakukan diharapkan dampak dari kebakaran hutan dapat ditanggulangi dengan cepat, tepat dan akurat. Manfaat yang akan didapat yatiu penanganan penanggulangan kebakaran hutan sehingga tidak meluas dan menyebabkan gangguan.

Abstract

Liquid smoke is the result of condensation of smoke from the pyrolysis process of biomass containing elements of lignin and cellulose. The chemical and physical components of liquid smoke were determined by the raw materials used. The purpose of this study was to determine the characteristics of liquid smoke from different plantation wastes. The raw material used consists of coconut shells, palm shells, and sawdust. Coconut shells were obtained from coconut milk traders in the Pangkalpinang market. Palm oil shells were taken from palm oil mill waste. Sawdust was a waste of wood craftsmen in Pangkalpinang. Liquid smoke was produced done by pyrolysis using a simple tool consisting of a plate with the main components of a combustion tube, a smoke conduit pipe, and a condensing tube. This study used a randomized block design with five replications. The results showed the highest yield of liquid smoke from coconut shell compared to palm shell liquid and sawdust liquid smoke. Coconut shell liquid smoke had a lower pH and water content than the liquid shell of palm oil and sawdust. The phenol content of coconut shell liquid smoke was 19.45 mg/ml, sawdust liquid smoke 8.24 mg/ml and oil palm shell liquid smoke 19.54 mg/ml. The acid content of coconut shell liquid smoke (7.44%) was higher than that of oil palm shell liquid smoke (5.70%) and sawdust (1.36%).Keywords: phenol, pyrolysis, coconut shell, oil palm shell AbstrakAsap cair merupakan hasil kondensasi asap dari proses pirolisis biomassa yang mengandung unsur lignin dan selulosa. Komponen kimia dan fisika asap cair ditentukan oleh bahan baku yang digunakan. Tujuan penelitian ini adalah untuk mengetahui karakteristik asap cair dari limbah komoditas perkebunan yang berbeda. Bahan baku yang digunakan terdiri dari tempurung kelapa, cangkang kelapa sawit dan serbuk gergaji. Tempurung kelapa diperoleh dari pedagang santan di pasar Pangkalpinang. Cangkang kelapa sawit diambil dari limbah pabrik kelapa sawit. Serbuk gergaji  merupakan limbah pengerajin kayu yang ada di Pangkalpinang.  Pembuatan asap cair dilakukan dengan pirolisis menggunakan alat sederhana yang tediri dari plat dengan komponen utama tabung pembakaran, pipa penyalur asap,  dan tabung kondensasi. Penelitian ini menggunakan rancangan acak kelompok dengan lima ulangan. Hasil penelitian menunjukkan rendemen asap cair dari tempurung kelapa paling tinggi dibandingkan dengan asap cair cangkang kelapa sawit dan serbuk gergaji. Asap cair tempurung kelapa mempunyai pH dan kadar air yang lebih rendah daripada asap cair cangkang kelapa sawit dan serbuk gergaji. Kandungan fenol asap cair tempurung kelapa 19,45 mg/ml, asap cair serbuk gergaji 8,24 mg/ml dan asap cair cangkang kelapa sawit 19,54 mg/ml. Kandungan  asam asap cair tempurung kelapa (7,44%) lebih tinggi  daripada asap cair cangkang kelapa sawit (5,70 %) dan serbuk gergaji (1,36 %).Kata kunci: fenol, pirolisis, tempurung kelapa, cangkang kelapa sawit

Abstract

Cream is a semi-solid emulsion dosage form of both water-in-oil (W/O) or oil in water (O/W) type containing one or more dissolved or dispersed ingredients in the corresponding base material (containing no less than 60% water). Cream is usually used as emollient or containing active pharmaceutical ingredients on the skin (Ansel, 2008). The advantage of cream are the application practicallity, water washeability, and the easiness to spread evenly. In this research, we formulated cream containing rhizome Galangal rhizome. According to Darmono (2008), Galangal rhizome has various properties such as antifungal and antibacterial activities. Galangal rhizome contains 1-asetoksikhavikol asetat (ACA). ACA is an antifungal. ACA has good solubility in 70% ethanol. We maserated Galangal rhizome (Alpinia galangal L.) to extract ACA from the simplicia. As for the cream base, we use hidrophilic base containing emulgators stearic acid and triethanolamine, with glycerin as humectant. During the optimization, we chose three formulas, formula 1 (10% stearic acid , 2% triethanolamin, 5% glycerin, and 0.01% vitamin E), formula 2 (15% stearic acid , 3% triethanolamin, 10% glycerin, and 0.05% vitamin E), and formula 3 (20% stearic acid, 4% triethanolamin, 7.5% glycerin, and 0.09% vitamin E). We used the bases to contain 10% of the extract. The results show that formula 1, formula 2, and formula 3 had typical smell of Galangal rhizome, brown color, and thick consistency. All formulas are homogenous. Formula 1 the best stability. We conclude that Galangal rhizome (Alpinia galanga L.) can be formulated in cream form with our formula 1 had the best stability among others.
