Abstract

Kerupuk ikan yang beredar dipasaran mengandung karbohidrat tinggi dan bahan tambahan makanan sintetis, seperti pengawet, penstabil warna, dan penambah cita rasa. Pembuatan kerupuk ikan dari ikan segar hasil tangkapan/panen nelayan dan bebas dari bahan tambahan makanan sintetis sebagai wujud kegiatan pengabdian kepada masyarakat dosen Politeknik Negeri Lhokseumawe di desa Jambo Timu Kecamatan Blang Mangat Kota Lhokseumwe. Kerupuk ikan yang dihasilkan akan lebih sehat dan aman untuk dikonsumsi. Pelatihan ini mendapat tanggapan serius dari peserta, pengelola TBM Hasan-Savvas dan perangkat desa. Pelatihan ini diikuti oleh 25 peserta ibu-ibu rumah tangga masyarakat nelayan. Semua peserta mengikutinya dengan tekun dan turut serta dengan aktif dalam semua tahapan pelatihan hingga selesai. Ikan yang digunakan adalah ikan bulan sebagai bahan baku karena harganya sangatlah rendah dan mengandung nilai gizi tinggi. Pembuatannya menggunakan bahan dan alat yang sederhana. Bahan yang digunakan tepung tapioka, daging ikan, telur, air, garam, gula, kunyit, dan bawang putih. Ada bebera tahapan pembuatannya. Tahap pertama, pembuatan adonan yaitu mencampurkan semua bahan yang digunakan dan telah dihaluskan sebelumnya. Tahap kedua, pencetakan dengan cara mendadar adonan menjadi lembaran-lembaran tipis kemudian dipotong-potong sesuai selera. Tahap ketiga, pengeringan dengan penjemuran dibawah sinar matahari langsung sampai kaku dan mudah patah. Tahap keempat, penggorengan menggunakan minyak dalam kemasan, kerupuk ikan siap disajikan. Kerupuk ikan yang dihasilkan sangat renyah, berwarna putih, rasanya enak, dan bentuknya sedikit melengkung. Kerupuk ikan harus dikemas dalam wadah tertutup agar tidak lembek dan terhindar dari faktor perusaknya. Kerupuk ikan dapat dijadikan alternatif usaha dalam meningkatkan ketentraman, kenyamanan kehidupan bermasyarakat nelayan. Kerupuk ikan dapat dipasarkan secara langsung atau setelah digoreng.Kata kunci— Kerupuk ikan, Ikan Bulan, Renyah, Bahan Tambahan Makanan Sintetis, Peluang Usaha, Pengemasan.

Abstract

Coffee parchment is a lignocellulosic waste material which has a potential to transform into synthesis gas. This research aims to study the feasibility of coffee parchment conversion under downdraft gasification with auto-heating supply method. The temperature profile in each zone of the reactor was investigated as the effect of different equivalence ratio (ER) as well as the producer gas characteristics such as ignition time, flame duration, colour and temperature, carbon conversion and producer gas composition. Initially, coffee parchment collected from dehulling process was sun-dried three to four days. The gasification was ignited by firing ca. 300 g of wood charcoal inside the reactor before the coffee parchment loaded, then the reactor was tighly closed. Once the combustible gas was produced, the gasification time was measured. The result shows that the highest operational temperature inside the reactor was 715.66 C within the combustion zone. The biomass conversion tends to increase by the increasing of ER, but the producer gas might dilute by more carbon dioxide production, and nitrogen input into the producer gas which indicated by the flame duration, colour, and temperature. Introducing an ER of 0.3 into the gasification reactor has provided adequate amount of oxygen to convert the coffee parchment into producer gas. This investigation suggests that coffee parchment is feasible to be converted into syngas. However, providing an advance process integrated to cleaning system would be required in the future to obtain a fuel grade syngas.

Abstract

ABSTRACT Research about application of natural zeolite (ZA) as adsorbent to absorb water in ethanol has been started. The purpose is, to evaluate the ability of ZA that have been activated in order to absorb water in ethanol. The activator that used is H2SO4 1N and HCl 1N solution. ZA crushed and sieved using a sieve 60, 80, and 100 meshes. A total of 35 grams of sifted ZA mixed with the activator and stirred for 30 minutes and then precipitated for 24 hours. Residue washed until neutral and heated using a furnace at a temperature of 400oC for 2 hours. ZA which has activated used to adsorb the water content in ethanol having a concentration of 60 %, 65 %, 70 %, and 80 %. The results showed that the activated zeolite by using H2SO4 1N solution to absorb water content in the ethanol have the efficiency until 19.7 %. However, the adsorption of water content in ethanol which has more than 60 % concentration, ethanol tends to adsorbed by ZA so that the water content in ethanol to be slightly higher compared with ethanol before adsorption.Keywords: Adsorben, zeolit, water content, activated, adsorbtion.
