Abstract

Mengkudu represent all purpose crop, there is many product that could be developed fromroot, bar, leaf, and also it’s fruit. The mengkudu’s fruit have carbohydrate content as much as 51,67gr. With the existence of the carbohydrate rate, it enables to be used to produce ethanol. The aim ofthis research is to determine the best condition process to make an ethanol from raw material ofmengkudu’s fruit. Ethanol yielded to be obtained heatedly from mengkudu’s fruit liquid by using HCL0,4 N in three neck gourd as hydrolysis process, so that we got the sugar rate equal to 8,23%. Afterthat can be made ferment media from sugar liquid result of the hydrolysis and enhanced by a startervolume at spanning : 4- 12%. Later fermented as according to variation time of between 24 until 72hours. The liquid result of the ferment dissociated by distillation, and the temperature maintenance for80 ºC.

Abstract

Komponen utama ampas tebu adalah serat (fiber) yang termasuk dalam syarat bahan baku yang dapat dijadikan pulp untuk pembuatan selulosa khususnya selulosa asetat. Asetilasi selulosa dari ampas tebu dalam pelarut asam phospat merupakan salah satu metode untuk menghasilkan selulosa asetat. Tujuan dari penelitian ini adalah untuk mempelajari pengaruh proses asetilasi terhadap kadar asetil selulosa asetat dengan variabel jumlah asam asetat glacial dan kecepatan pengadukan . Proses asetilasi dilakukan dengan mereaksikan selulosa yang terbuat dari ampas tebu dan asam asetat glacial dalam sebuah reactor dengan menggunakan motor pengaduk. Prosesnya terdiri dari beberapa tahap. Tahap pertama adalah pembuatan selulosa yang kemudian dimurnikan. Tahap kedua adalah melarutkan selulosa ke dalam asam phospat dan mengasetilasi selulosa dengan asam asetat glacial dan tahap pemulihan produk dengan cara penyaringan dan pengeringan. Dalam penelitian akan dipelajari pengaruh pemberian volume asam asetat glacial 98% sebanyak 20, 40, 60, 80 dan 100 ml dengan kecepatan pengadukan sebesar 100, 200, 300, 400 dan 500 rpm terhadap kadar asetil dari selulosa. Dari hasil penelitian ini didapat kadar asetil terbesar adalah 45,16% pada pemberian volume asam asetat glacial 60 ml dengan kecepatan pengadukan 300 rpm.

Abstract

Metode pembuatan Asam oksalat ini secara umum adalah dengan proses Peleburan Alkali. Pada awal proses, Sabut Siwalan dikeringkan dan diayak sesuai ukuran. Ambil 20 gram Sabut Siwalan dan campurkan NaOH sesuai variabel (15, 20, 25, dan 30 %). Kemudian campuran kedua bahan tersebut dipanaskan pada suhu ±150oC dalam waktu sesuai variabel (50 ; 75 ; 100; 125  menit). Selanjutnya di filtrasi menjadi Natrium Oksalat (Na2C2O4), lalu ditambahkan CaCl2 dan diperoleh filtrat NaCl dan endapan CaC2O4. Untuk melarutkan endapan kalsium oksalat ditambahkan H2SO4, sehingga diperoleh filtrat asam oksalat (C2H2O4) dan endapan kalsium sulfate (Ca SO4). Filtrat asam oksalat sebagai produk. Pada penelitian yang telah dilakukan selulosa yang terdapat dalam Sabut Siwalan dapat diolah menjadi asam oksalat. Pada pembuatan asam oksalat ini dipengaruhi oleh waktu peleburan serta konsentrasi pelarut. Hasil asam oksalat terbaik diperoleh pada konsentrasi 20% dan waktu peleburan 100 menit dnegan kadar asam oksalat sebesar 63,311%.DOI : https://doi.org/10.33005/tekkim.v12i2.1086

Abstract

The Lapindo mudflow disaster in East Java Province, or also known as LUSI (LUmpur “mud”-SIdoarjo) has become spectacular longest ongoing disaster in recent memory since 2006. The utilization of volcanic Lapindo mud could be the promising solution to prevent further environmental damage. The chemical composition of Lapindo mud contained of 44.1% SiO2, 23.7% Fe2O3, 13% Al2O3, 7.02% CaO, 5.35% MoO3, 2.53% K2O, 1.84% TiO2 and 0.7% Na2O. Aluminium sulfate (Al2(SO4)3) or “alum” have been widely used as coagulation compound in water treatment, paper and textiles industry. Aluminium sulfate can be synthesized from aluminium oxide (Al2O3) from Lapindo mud with acidic solutions (H2SO4). The aim of this work was to synthesize aluminum sulfate from Lapindo mud by using extraction process. The impact of H2SO4 concentration and heating time to the production of aluminium sulfate have been investigated. The results showed that the aluminium sulfate can be synthesized from Lapindo mud by using H2SO4. Based on XRF analysis, the variation of heating time and H2SO4 concentration affect the aluminium sulfate conversion. The increasing of heating time and H2SO4 concentration directly enhance the conversion until reach the optimum condition. The optimum condition for aluminium sulfate synthesis from Lapindo mud (75.78% conversion) was found to be 90 min for heating time with H2SO4 concentration of 80%

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

Geothermal sludge is a waste product from geothermal where it contains SiO2 which can be used as fertilizer. In this study, the making of silica ammonium fertilizer was carried out by taking salicy acid from geothermal sludge by extracting and adding resin which was then modified with NH4OH addition. Extraction was done using 1000 ml of KOH 1 N to dissolve 60 grams of Geothermal Sludge. Resins are added with variations in resin weight, namely, 5, 10, 20, 30, and 40 grams. NH4OH was added with variations in concentrations namely 3, 6, 9, 12 and 15% with a ratio of filtrate and NH4OH solution of 1: 1. The resulting ammonium silica inorganic liquid fertilizer products were analyzed for free silica and ammonia levels. The results of this study indicate that the levels of free silica and ammonia are influenced by the weight of the resin used and the concentration of ammonium hydroxide mixed. From the results of the research, it was found that inorganic silica liquid fertilizer with the highest SiO2 content in ammonium silica liquid fertilizer occurred when adding 20 grams of resin with the addition of NH4OH with a concentration of 15% which was 1,831.87 mg / L while the highest NH3 content in fertilizer liquid ammonium silica occurs when adding 40 grams of resin with the addition of NH4OH with a concentration of 15% which is equal to 252,312.80 mg / L.
