Abstract

This research was aimed to produce and to analyze the quality and chemical composition of liquid smoke from bamboo waste by pyrolisis process. Temperatur of pyrolisis reactor were 140 oC, 180 oC, 220 oC, 260 oC and 300 oC for 5 hours to produce liquid smoke. Liquid smoke purified by filtration, distillation and adsorption. Resulted liquid smoke were analyzed yield, acidity, and density. Identifying the chemical composition of liquid smoke was by Gas Chromatography and Mass Spectrometry (GC-MS).  Yield of liquid smoke 1,6977% up to 3,9713 %; Acidity of  liquid smoke were 1.49 up to 1,9; the density of liquid smoke 1,004 up to 1,045. The results of GC-MS test showed that chemical composition of the liquid smoke have Phenolic compounds 0,5 – 0,6ppm and liquid smoke found not containing of carsinogenic Benz (a) Pyrene.

Abstract

Fish wastes such as fish bones and scales have a potential to be used as a gelatin source. It can be used as an alternative material to replace pork or bovine which ordinarily conflicted with religion issue. Gelatin from fish has different characteristics compared with mammalian source. It has several advantageous properties such as high amount of hydrophobic amino acids, less proline and hydroxy proline, lower gelling ability, and melting point. In this study, gelatin was produced from fish waste especially snapper scales using the bromelain enzyme at the pre-treatment stage to improve its characteristic. The snapper scales soaking in hot water at 80⁰C for about 30 minutes to remove the fat which attached the scales. A pre-treatment has been conducted using bromelain enzyme solution at various concentrations of 1%, 2%, 3%, 4% and 5% for 6 hours to remove non-collagenous proteins and loosen the bonds of the fish scales. The next step is demineralization using a 15% concentration of citric acid solution for 3 days. The ossein formed in the demineralization stage was then hydrolyzed at 50⁰C and 70⁰C for 9 hours with stirring at 300 rpm. The best gelatin yield was obtained from the pretreatment of bromelain enzyme solution with a concentration of 3% at a hydrolysis temperature of 70⁰C with a yield of 9.13%, pH value of 3.86, water content of 8%, ash content of 0.80%. FTIR spectra shows the presence of functional groups correspond to gelatin formation, such as carbon, hydrogen, hydroxyl group (O-H), carbonyl group (C=O), amine group (N-H) and alkene group (C=C). The heavy metal content test showed that the gelatin contained no heavy metal content of lead (Pb), mercury (Hg), cadmium (Cd) and arsenic (As).

Abstract

This research is to study the effect of ethanol fermentation aerobic pH on acetic acid product. Anaerobic fermentation uses saccharomyces cerevisiae to produce ethanol, and aerobic fermentation uses acetobacter acetic for acetic acid production. In aerobic ethanol fermentation using pH 3; 3.5; 4 and 5. The ethanol concentration was evaluated using GC ULTRA Scientific Gas Chromatography, DSQ II detector, and MS 220 column. Acetic acid produced was analyzed using an alkalymetric method. Anaerobic fermentation uses Saccharomyces cerevisiae with 1-day log phase, while aerobic fermentation uses acetobacter aceti with a 5-day log phase. Fermentation using saccharomyces cerevisiae within 24 hours so that reduction sugar could stably decrease, optimum ethanol could be got at optimum pH 6 which could decrease 55 % of reducing sugar concentration to produce 8,20583 %v/v ethanol. Fermentation acetate acid content observed in 3 days at pH 6 and 30 ⁰C will produce 6,659 g/l also shows that pH 4-6 at 30 ⁰C will produce 6,605 g/l acetate acid. Aerobic fermentation of acetate acid in 3 days shows that pH 4-6 is highly affected by temperature at 30⁰C. Statistical analysis shows, in ethanol production pH and fermentation time give significant effect, but interaction has no significant effect.

Abstract

Aluminum Fluoride (AlF3) is a substantive material used to reduce the melting point temperature of the Aluminum from 1500oC to 600-850oC. The production applies a wet process using raw materials of Fluosilicic Acid and Aluminum Hydroxide with a by-product of Silica Dioxide. In this case, AlF3 products are expected to have a maximum H2O content of 2.6%. However, in the production process, the H2O content reached 3% due to the inoptimum drying process. Therefore, the optimization process was carried out by increasing the dry air temperature of the recycle from stage 2 to stage 1 in the drying process, so that the mass transfer of H2O from AlF3 crystals to the air can be maximized. After the optimization, it was found that the H2O content has met the quality standard of 1.8%.

Abstract

Sejak lama Negara Indonesia memiliki potensi besar dalam industri halal karena mayoritas penduduknya memeluk agama Islam. Langkah pemerintah Indonesia semakin jelas terlihat dengan diberlakukannya UU No. 33 tahun 2014 dan PP No. 31 tahun 2019 tentang Jaminan Produk Halal (JPH) yang mengatur perubahan sistem prosedur dan registrasi sertifikasi halal dari bersifat sukarela menjadi wajib sejak 17 Oktober 2019. Hal tersebut berdampak pada seluruh pelaku usaha. Tak terkecuali pelaku UMKM binaan dari Koperasi Wanita Setia Bhakti Wanita Surabaya. Koperasi Wanita yang berdiri sejak 1975 telah memiliki 13.615 anggota dan ratusan binaan UMKM. Pelaku UMKM binaan Kopwan SBW belum mengetahui pentingnya sertifikasi halal dan prosedural pendaftarannya. Oleh karena itu, peran perguruan tinggi hadir dalam kegiatan pengabdian kepada masyarakat untuk mendampingi para UMKM binaan Kopwan SBW mengurus sertifikasi halal. Terdapat 4 strategi kegiatan yang dilakukan dalam pengabdian kepada masyarakat ini. Strategi yang pertama yaitu berdiskusi dalam rangka menyampaikan ide gagasan jangka pendek dan Panjang kepada pengurus Koperasi Wanita Setia Bhakti Wanita Surabaya. Strategi selanjutnya adalah mendaftarkan para UMKM binaan dalam pelatihan Kader Penggerak Halal (KPH) yang dilaksanakan kolektif oleh Pusat Kajian Halal ITS. Setelah itu melakukan visitasi dan pendampingan langsung kepada masing-masing UMKM binaan dan strategi yang terakhir adalah pemetaan binaan UMKM dalam mengikuti program bimbingan teknis audit halal atau program sertifikasi halal gratis (SEHATI). Harapan dari pengabdian masyarakat ini adalah dapat memberdayakan para binaan UMKM untuk bersaing produk halal di industri halal dalam skala internasional.

Abstract

Tujuan dari pengabdian masyarakat ini yaitu peningkatan kemampuan Guru Pengajar jurusan Keteknik Kimiaan se-Jawa Timur dalam bidang pengolahan limbah cair untuk mendukung kegiatan belajar-mengajar dalam bidang teknik kimia. Workshop ini dimaksudkan untuk memberi bekal mendasar dengan memberikan pemahaman ilmu dan perhitungan terkait bidang keteknikkimiaan sehingga menjadi acuan saat melakukan praktek dan meningkatkan kemampuan secara praktikal. Hal ini diharapkan dapat mendukung merealisasikan misi SMK jurusan Keteknik Kimiaan di Jawa Timur untuk menghasilkan tenaga kerja yang profesional sesuai dengan tuntutan dunia usaha/industri. Kegiatan peningkatan kemampuan sumber daya guru pengajar teknik kimia di SMK Jawa Timur tidak bisa dilakukan sekaligus atau bahkan hanya beberapa jam atau beberapa hari saja, namun kegiatan tersebut harus diberikan secara mendasar, bertahap dan terencana. Pada tahap ini, sesuai dengan pembicaraan dan kesepakatan dengan pihak mitra yang merupakan pengguna langsung kegiatan ini, peningkatan kemampuan yang diberikan berupa Pendalaman Teori dan Praktek Pengolahan Limbah Cair. Program pelatihan guru-guru jurusan Keteknik Kimiaan dilakukan dalam bentuk Daring sebagai bentuk pengabdian kepada masyarakat yang dilakukan oleh dosen-dosen Departemen Teknik Kimia Industri Fakultas Vokasi –ITS dengan total jam pelatihan adalah 32 jam, mengingat kondisi pandemi Covid-19 saat ini yang tidak memungkinkan untuk mengadakan pelatihan secara tatap muka (offline/Luring).
