Abstract

Counseling and training of the Abdimas Program is an application of research results to make various fish products based on fish as an alternative high nutritious food products and a chance to be developed in Gang Dolly residents Surabaya to increase revenue.The method used in facilitating the improvement of fish processing skills in the area of Gang Dolly Surabaya is to conduct training with training methods are: lecture method, practice method and advisory methods for the sustainability of business activities and marketing results.The existing objective condition is that the low productivity of fishery producers produced during this time is more due to the weakness of human resources in the field of management, less professional organization, lack of mastery of processing technology and weak information and marketing, and the low quality of entrepreneurship from business actors. For this purpose, the training was conducted by the mothers of Putat Jaya (Gang Dolly) residents in making crackers from Manyung fish.In the field of economy or business, fish manyung is an economical fish that is important as a consumption fish that can be used as a money-producing material. Compared with the tengiri fish that are widely used as fish crackers, manyung fish is more promising to make money because the price of manyung fish is relatively cheaper than fish tengiri. And certainly the protein content in manyung fish is very high.

Abstract

Sidoarjo hot mud has erupted for the past 16 years and has many effects on the environment. This mud contains several porous materials, such as silica and aluminum oxide, which can be used as adsorbents. This study aimed to characterize the morphology of the adsorbent and apply it to waste cooking oil purification. The composition of virgin hot mud was 46.5% SiO2 and 13% Al2O3 with an amorphous crystalline structure. The hot mud was activated with H2SO4 under different drying process conditions where the drying temperature differed from 150oC to 250oC, while the drying period was set from 30 to 90 minutes. After the activation, the structure of the adsorbent became more crystalline. From XRD analysis, the lowest intensity resulted from adsorbent with 225oC and 75 minutes of drying, with 191,038 m2/gr on pore surface area. This adsorbent had a greater pore surface area and gave the best adsorption process.

Abstract

Bioplastics are plastics made from natural materials such as starch, seeds, and tubers, then added cellulose such as nata. Bioplastics are easily degraded by microorganisms or moisture. Pineapple peel is a part of pineapple fruit that has been underutilized so it ends up as waste. The high carbohydrate content in pineapple fruit skin can potentially be used as raw material for making nata, with the addition of rice washing water which contains carbohydrates, starch, vitamin B1, vitamin B6, and vitamin B3 which can be utilized by microorganisms as a medium for making nata. The resulting nata is used as raw material for making bioplastics because the cellulose content in nata is quite high. The results of the analysis of cellulose content in the nata produced amounted to 42.78%. This study aims to make bioplastics from pineapple peel nata and rice washing water that meet the Japanesse Industrial Standard (JIS). The method of making bioplastics used is the solution casting method. The variables used in making this bioplastic are 15 grams of nata, plus 3.5 grams of chitosan with 500 rpm stirring for 10 minutes at 70 °C with the addition of glycerol variations of 2; 2.5; 3; 3.5, and 4% and variations of CMC ingredients 4; 6; 8; 10 and 12%. From the results of the study, the best results of bioplastics, namely the tensile strength value of 0.51 MPa, elongation of 71.49%, water resistance of 55.61%, and biodegradation of 35.81%, were obtained in the addition of CMC 8% and glycerol added 3.5%. The results of the bioplastic SEM test obtained a very tight and fairly flat bioplastic structure. In addition, the FTIR test found that bioplastics have 5 peaks where the 5 peaks represent the forming functional groups of bioplastics such as O-H functional groups.

Abstract

The bio briquette is a type of briquette that is derived from agricultural waste since it is intentionally produced using biomass charcoal. The processing of agricultural waste, such as mushroom planting material, into bio briquettes is characterized by its low cost. When bio briquettes undergo appropriate and accurate processing, they can yield briquettes of superior quality. The primary objective of this research endeavor was to generate a biobriquette using an agricultural byproduct derived from mushroom farming, while concurrently assessing the distinct attributes and properties of said biobriquette. The research utilized a total of 400 grams of waste from mushroom culture materials, together with an adhesive composed of 40 grams of starch. The briquette dough is subsequently extruded in a cylindrical shape. Subsequently, the mold briquettes are subjected to a heating process at a temperature of 80°C for 5 hours, to decrease the moisture content. The outcome of the smoke test indicates that the emission of smoke will cease after 75 seconds. In the conducted Combustion of Speed Test, the obtained findings indicate a combustion rate of 0.425 grams per minute, using an initial sample weight of 5.8 grams. The ash content yielded a reading of 10.6%.

Abstract

Bioethanol is an alcohol molecule that is derived through the process of fermentation using microorganisms. Fermentation is a biological process in which microbes metabolize fermentable sugars as a source of nourishment, resulting in the production of ethyl alcohol and various other byproducts. These microbes commonly metabolize 6-carbon carbohydrates, with glucose being one of the most prevalent examples. Hence, biomass materials rich in glucose or glucose precursors are the most readily convertible to bioethanol. The examination of bioethanols employing Saccharomyces bayanus demonstrated notable disparities in the obtained alcohol concentration. The utilization of Saccharomyces bayanus yeast, in the absence of sugar supplementation, for the conversion of grape into bioethanol, yielded a modest alcohol concentration of merely 14%. In the context of bioethanol production, pineapple was utilized as a substrate, wherein 4 grams of Saccharomyces bayanus yeast and an additional 70 grams of sugar were introduced as a nutritional supply to support yeast growth and metabolism. The present fermentation procedure resulted in an alcohol concentration of around 21%.
