Abstract

Bahan Bakar Minyak sudah menjadi bagian dari kebutuhan masyarakat. Namun karena deposit minyak bumi di Indonesia hanya tinggal  20 tahun maka harus dicari bahan bakar alternatif lain yang dapat menggantikan minyak tanah. Bioetanol merupakan bahan bakar alternatif yang potensial karena sumbernya mudah diperbaharui. Tujuan penelitian ini adalah untuk mengetahui pengaruh penambahan  volume C2H5OH dan lama pengadukan terhadap hasil nilai flash point etanol gel dari cangkang kerang hijau dan etanol. Cangkang kerang hijau yang telah dihaluskan dimasukkan dalam beaker glass kemudian dicampur dengan asam asetat (CH3COOH), kalsium asetat (Ca(CH3COO)2) yang terbentuk dicampur dengan etanol 85% sesuai variabel volume etanol yaitu (70;75;80;85;90 ml), diaduk selama waktu sesuai variabel yaitu (30;60;90;120;150 menit) kemudian didiamkan sampai terbentuk etanol gel. Kemudian disaring untuk diambil etanol gelnya dan dianalisakan flash pointnya. Hasil penelitian  menunjukkan bahwa semakin lama waktu pengadukan   nilai flash point menurun. Hasil terbaik yang diperoleh yaitu flash point sebesar 16,80 oC yang didapat pada volume etanol 75 ml dan waktu pengadukan 150 menit.

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

ZA fertilizer waste (Ammonium sulfate) is waste generated from the industrial process of producing ZA fertilizer. The waste contains very high calcium and has the potential to be used as a raw material in the manufacture of Precipitated Calcium Carbonate (PCC). PCC with certain qualities can be developed in the field of advanced materials, with size modification into nanoparticles. One method to produce nanoparticles is using the coprecipitation method, with the help of a polymer solution. This study aims to produce Nano-PCC by finding the best conditions of CaCl2: Ethylene Glycol mole ratio and stirring speed. Nano-PCC is synthesized by reacting fertilizer waste with HCl to form a CaCl2 solution. Then, the solution is mixed with ethylene glycol to prevent particle agglomeration so that the size obtained will be smaller. The mixture is then reacted with Na2CO3 to form precipitated calcium carbonate (PCC). In this study, the variables were the mole ratio of CaCl2: ethylene glycol (1:12, 1:14, 1:18, 1:20) and stirring speed (350, 500, 650, 800, and 950 rpm). Based on PSA analysis, the Nano-PCC obtained at the smallest CaCl2: ethylene glycol ratio 1:12, stirring speed 950 rpm was 51.83 nm. Based on Scherrer’s calculations with XRD, the particle size obtained was 48.25 nm. SEM analysis showed that the crystals formed were dominated by vaterite crystals, with a size range of 55.71-607.79 nm.

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

With the policy of revoking the SP-36 fertilizer subsidy in 2022, an alternative is needed to minimize idle capacity and cost efficiency caused by stopping operations at the Phosphate I Fertilizer Unit. Based on national fertilizer stock data for NPK 15-10-12 fertilizer, there is a gap between the actual stock nationally and the minimum stock. The low actual stock nationally can lead to a scarcity of NPK fertilizer which can affect national food security. So as an alternative solution to solving the problem, the Phosphate I Fertilizer Factory is utilized to be able to produce NPK fertilizer. This problem is solved by using the PDCA Cycle (Plan-Do-Check-Action) method. Based on the data and facts in the field, it is known that the existing equipment condition of the Phosphate I Fertilizer Unit has not been able to produce NPK fertilizer. The results of the project found the best solution to the problem of equipment conditions at the Phosphate Fertilizer Unit I by modifying the feeding system facility which was originally manual to weigher based by installing 3 hoppers, dozometers, BC mixing, and DAP crusher in the Curing 250 Warehouse, then installing coating facilities and coloring NPK fertilizer on the existing cooler in the Phosphate I Fertilizer Unit, making key operating parameters, and conducting an On Job Training scheme for the Phosphate I Fertilizer Unit personnel at the NPK II/III/IV Plant. So with this modification, the Phosphate Fertilizer Factory I is expected to be able to produce NPK fertilizer.
