Abstract

Mesoporous silica is a versatile material characterized by its highly ordered nanoporous structure with pore diameters ranging from 2 to 50 nanometers. This unique structure provides a large surface area and volume, making mesoporous silica an excellent candidate for various applications in adsorption, drug delivery, catalysis, and environmental remediation. Mesoporous silica can be synthesized using commercial or natural silica precursors such as mineral clay and other natural sources. Promising alternative sources of silica for synthesizing mesoporous materials encompass a range of materials, including various clay minerals such as kaolin, rectorite, halloysite, montmorillonite, sepiolite, hectorite, bentonite, talc, muscovite, paragonite, palygorskite, and chlorite. Other natural sources like beach sand, geothermal sludge, and sepiolite also show significant potential for mesoporous material synthesis. However, these sources have not been extensively explored and warrant further investigation in the field. The mesoporous silica from natural sources has been widely used as a catalyst for biofuel production via hydrocracking, catalytic cracking, and deoxygenation reactions

Abstract

Setiap industri membutuhkan air pendingin (cooling water) sebagai unit pendukung dalam proses produksinya, termasuk industri petrokimia yang memerlukan air pendingin (cooling water) agar proses produksinya dapat berjalan dengan lancar. Untuk meningkatkan serta menjaga penggunaan air pendingin (cooling water) , maka digunakan alat cooling tower yang berfungsi untuk me-recycle air kondensat menjadi air pendingin (cooling water) kembali. Penggunaan alat cooling tower ini dinilai sangat penting, sehingga diperlukan analisa evaluasi kinerja alat untuk mengetahui kondisi cooling tower dan mencegah kerusakan dikemudian hari. Evaluasi tersebut berdasarkan nilai efisiensi kerja serta termal cooling tower dan perhitungan neraca massa pada sistem cooling tower CT-22111 A-B. Analisa evaluasi ini dapat menjadi hal yang di pertimbangan oleh teknis pihak industri untuk melakukan perawatan lebih lanjut serta operasional. Dari Analisa data lapangan serta data pendukung didapatkan hasil aktual yang menunjukkan di mana cooling tower pada unit utilitas departemen produksi IA diperoleh sebesar 71% untuk desain dan 77% untuk aktual serta untuk efisiensi termal masih direntang 67% - 81% tidak terlalu berbeda dengan data desain untuk efisiensi termal. Dengan demikian, kinerja cooling tower menunjukkan bahwa masih beroperasi dengan cukup baik.

Abstract

Glagah District, located in Lamongan Regency, has a lot of potential that can still be optimized, one of which is fish processing. This area produces popular fish on the market and only becomes waste if not processed, such as small fish, fish with too many spines, and fish heads. This is the main concern in processing unsold fish as one of the main raw materials in the production of fish meal. Mapping fish processing sources aims to build and maximize fish production potential. The method used is a descriptive and qualitative method with a field survey to obtain an overview of the distribution points of fish processing sources. From the results of field surveys and mapping carried out, there are 196.2456 hectares, including swamps, rivers and reservoirs, with a production scale of around 125.4635 tons. Meanwhile, the results of aquaculture include fish ponds, rice fields, ponds, floating-net-cages, and step-net-cages, which cover an area of around 4,179.48 hectares with a production scale of 12,915.9608 tons. The use of fish includes flour, pellets, crackers, presto, and fish cake, which can add selling value. This can also be a way to reduce fish and increase the village's income.

Abstract

Indonesia has committed to climate change mitigation through a sustainable energy transition. Currently, the share of renewable energy in Indonesia’s energy mix only reaches 12 %. One type of renewable energy that the Indonesian government is focusing on is biofuel to reduce consumption and dependence on fossil fuels. Bio-oil produced through pyrolysis has the potential to be used as a biofuel. The chosen pyrolysis process is Co-Pyrolysis, which involves two or more feedstocks. In this study, the process was carried out using waste cooking oil (WCO) and HDPE waste as feedstocks. The process was conducted at 450°C for 30 minutes, with varying masses of both feedstocks. The data obtained were analyzed using mass balance and yield analysis to determine the optimal conditions for producing bio-oil as a hydrocarbon fuel. The optimal condition was found at a mass ratio of HDPE: WCO = 1:4, with a bio-oil yield of 78%. Under these optimal conditions, the conversion of HDPE plastic into heptadecane was 29.39%, and the conversion of oleic acid in waste cooking oil into heptadecane was 38.8%. This also serves as an initial step toward developing a pilot plant-scale process using HDPE plastic waste and waste cooking oil.
