Abstract

Penelitian ini bertujuan untuk mensintesis katalis Co-Mn/TiO2 dengan metode impregnasi. Tahapan penelitian meliputi refluks larutan Co-Mn, impregnasi katalis Co-Mn/TiO2, kalsinasi katalis Co-Mn/TiO2 dan karakterisasi. Karakterisasi katalis Co-Mn/TiO2 dilakukan menggunakan SEM-EDX dan XRD, pengujian yang dilakukan adalah menghitung luas permukaan katalis Co-Mn/TiO2. Hasil penelitian yang didapatkan menunjukkan berat campuran Co-Mn dan suhu kalsinasi mempengaruhi luas permukaan. Hasil pengujian luas permukaan didapatkan katalis (Co-Mn) 20% /TiO2 pada suhu kalsinasi 800 0C yang terbesar yaitu 172.28 m2/g.

Abstract

Modification of polyurethane by adding fillers such as bentonite can improve the physical properties of polyurethane coatings. Polyurethane synthesis is carried out using the prepolymer method by reacting toluene diisocyanate (TDI) with palm oil based polyols. Bentonite addition is used to provide heat resistance in polyurethane coating material. The concentration of bentonite used was 1.5% b / b, 3.5% b / b, and 5.5% b / b. The resulting polyol synthesis will be analyzed using FTIR to see the OH group formed. The bentonite purification process was carried out by using cetyltrimethyl ammonium bromide in bentonite solution. The target in this study is the anti-bacterial properties of the products produced. Whereas to see the characteristics carried out SEM and FTIR analysis

Abstract

This research has been carried out in cellulose membrane production from bacterial cellulose. Bacterial cellulose is produced from the fermentation process. The purpose of this study was to analysis the effect of cmc, glycerol and fermentation time towards cellulose membrane characteristics. Cellulose membrane made of a combination of coconut water and palm sugar juice as medium fermentation by using Acetobacter xylinum at 2, 4 and 6 days for fermentation time. Cellulose membrane obtained from a mixture of bacterial cellulose, cmc and glycerol. The addition of cmc and glycerol to improve cellulose membrane characteristics and performance. Based on the analysis results obtained the best performance at 4 days of fermentation time with a concentration of 1.5% cmc and 1.5% glycerol. The thickness of the cellulose membrane was almost the same for all samples and does not affect significantly towards the fermentation time for cellulose membrane production. Cellulose membrane has an asymmetric shape based on morphological analysis using SEM. Besides cellulose membrane has a similar pattern to the weight reduction and has the addition of heat resistance of the membrane. While the results of the IR spectra of cellulose membrane to detect the presence of OH groups, CO, C=C and CH groups that are characteristic of the polymer

Abstract

Salah satu bentuk peningkatan ekonomi masyarakat dilakukan dengan memberikan pelatihan yang mudah dan murah, seperti halnya pada desa Alue Liem Kecamatan Blang Mangat. Dengan tingkat perekeomian yang cukup memmadai keberadaan desa ini dilintasi oleh jalan Line Pipa dan Jalan menuju Simpang keramat sangat potensi untuk pengembangan usaha kreatif seperti pembuatan sabun cair. Pealtihan ini dilakukan oleh Tim Politeknik Negeri Lhokseumawe yang diikuti oleh ibu-ibu dan remaja putrid desa tersebut. Dari hasil pelatihan para peserta dapat melakukan pembuatan sabun caiar secara mandiri dan direncanakan adanya pemasaran dengan harga yang bersaing dengan sabun kemasan namun dengan kualitas yang sesuai dengan standar sabun yang digunakan pada umumnya. Langkah selanjutnya adalah melakukan bimbingan terhadap pengembangan usaha melalui pendampingan terhadap perijinan dan bantuan pemsaran.Kata kunci: Ekonomi, Sabun cair, Pelatihan, KreatifPENDAHULUANDesa Alu Lim Kecamatan Blang Mangat Kota Lhokseumawe dengan jarak hanya lebih kuang 6 Km dari kampus Politeknik Negeri Lhokseumawe memiliki jumlah penduduk sebanyak 2939 jiwa. Sebagian besar mata pencarian penduduk-nya adalah Tukang, Buruh, Petani dan Pedagang dan rata-rata tingkat pendidikan masyarakatnya adalah Tingkat SD dan SMP. Lokasi desa ini berada pada lintasan jalan Line pipa antara Exxon Mobil ke Petra Arun Gas (PAG), sehingga ini menjadi salah satu potensi dalam pengembangan perekonomian dan peningkatan tarap hidup masyarakat.Potensi ini belum termanfaatkan secara maksimal

Abstract

ABSTRAK Penelitian ini dilakukan untuk mempersiapkan adsorben berbahan baku kaolin alam yang dimodifikasi CTAB untuk menyisihkan ion logam Fe2+ dari permukaan air. Kaolin alam dicuci dengan air suling dan selanjutnya dikeringkan dalam oven dryer, Kaolin selanjutnya di aktivasi dengan HCL 1 N, dan di modifikasi dengan surfaktan CTAB dengan perbandungan 45% dari berat kaolin. Proses penyerapan dilakukan dengan mencampurkan 2 gram adsorben yang telah dimodifikasi pada 100 ml sampel air yang mengandung 3 ppm ion logam Fe2+ diikuti dengan pengadukan 100 rpm, pH 5, dan suhu 300C. Konsentrasi Fe2+ pada permukaan air dianalisa dengan menggunakan AAS setiap selang waktu tertentu dalam periode 20 – 100 menit. Hasil penelitian menunjukkan bahwa kemampuan adsorben kaolin tanpa modifikasi mampu menurunkan konsentrasi Fe2+ sebesar 62,23% selama 40 menit, sedangkan adsorben dari kaolin modifikasi surfaktan pada awal proses mampu menurunkan konsentrasi Fe2+ mencapai 73,8% pada waktu 10 menit. Hasil karakterisasi SEM menunjukkan bahwa adsorben kaolin modifikasi mampu menyerap ion logam Fe2+ lebih banyak dalam waktu singkat karena mempunyai permukaan kontak yang luas dan juga mempunyai struktur permukaan acak, dibandingkan dengan adsorben kaolin yang tidak modifikasi surfaktan mempunyai struktur morfologinya yang beraturan. Kata kunci : Adsorpsi, Fe, Adsorben, Kaolin, CTAB

Abstract

The use of cooking oil repeatedly at high temperatures will cause the quality and nutritional value of fried foods to decrease, which can have a negative impact on consumer health. Repeated use will increase the levels of free fatty acids (ALB) in cooking oil so that it will have a negative impact on the health of people who consume it or use it as a heating medium (frying). The adsorption process is carried out by contacting used cooking oil and adsorbent in the composition Because of this, the idea arose to use noni as an adsorbent for refining used cooking oil by means of adsorption using a mixture of noni (M) and kaolin (K) by varying the composition and contact time. The function of this adsorbent is generally to absorb impurities, odors and chemical substances that are toxic in used cooking oil. Ascorbic acid contained in noni fruit also functions as an anti-oxidant, namely a substance that is able to neutralize the peroxide groups contained in used cooking oil.

The adsorption process is carried out by contacting used cooking oil and adsorbent in the composition (100:0 ; 75:25 ; 50:50 ; 25:75 ; 0:100) for 30, 60, 90 and 120 minutes respectively with activated and unactivated kaolin as the control variable. The oil after adsorption was then observed for changes in acid number, peroxide value, moisture content, impurities content and color intensity. In several studies, the quality of oil recovered from used cooking oil showed a slightly blackish color, making the oil look less attractive. The use of kaolin as a bleaching earth in refining used cooking oil is due to the high SiO2 content in kaolin, which is expected to improve the color of used cooking oil, especially to improve the color of the recovered oil, so that it approaches the quality of standard cooking oil used in the market.Keywords: adsorbent; free fatty acids; noni; used cooking oil; kaolin
