Abstract

This study aims to evaluate the effect of wheat flour, starch, and sago adhesive variations on the characteristics of corn cob-based biobriquettes. Against the backdrop of fossil fuel scarcity and the abundance of corn cob waste, this research offers a solution to utilize the waste as an alternative fuel in the form of briquettes. The use of adhesives is an important element in the manufacture of quality briquettes. Adhesives not only play a role in maintaining the density of briquettes, but also affect the overall quality of the product. Different types of adhesives will result in different briquette quality, due to the different chemical compositions among the adhesives. The use of three types of adhesives with varying concentrations is expected to affect the quality of the briquettes based on SNI 01-6235-2000 standards. Testing the characteristics of biobriquettes includes moisture content, ash content, calorific value, and combustion rate. The results of this study found that the most optimal biobriquettes were 15% tapioca adhesive with the highest calorific value of 5563.13 cal/g, water content of 1.96%, ash content of 3%, volatile matter content of 5.76%, bound carbon content of 89.28%, and burning rate of 0.49 g/min. The biobriquettes have met SNI-01-6235-2000.

Abstract

Batu Malang City is the largest apple producing area in East Java. The apples produced sometimes do not meet market specifications. UMKM CV. Andhini uses the apples as raw material for apple chips. The problem faced by UMKM is the high cost of electricity to freeze apples for 24 hours in the freezer before the apples are fried. In addition, there are also complaints about the price of coconut oil for frying apple chips. This community service program provides a solution by using a 2% concentration CaCl2 solution to soak apples for 40 minutes before frying. Expensive coconut oil is replaced with packaged oil which is a mixture of coconut oil and palm oil at a cheaper price. The two solutions produce crispy apple chips, evenly cooked and with a fragrant aroma like coconut oil. UMKM owners expressed satisfaction with the products produced. The problem of high electricity costs and high coconut oil prices can be overcome.

Abstract

The use of rice husks as a raw material for briquettes helps reduce agricultural waste while providing added economic value to the product. Molasses is a by-product of the sugar-making process, which is abundant and often not utilized optimally. Molasses has the advantage of being a biobriquette adhesive because it is relatively cheap, easily biodegradable, and environmentally friendly. Albumin in egg white has the ability to form a gel when heated or dried, so it can potentially help bind biomass particles such as rice husks compared to other adhesives. The research operating conditions include raw materials, namely rice husk, carbonization temperature of 300℃, carbonization time of 1 hour, briquette size ≥ 150 mesh, type of adhesive (molasses and egg white) and adhesive concentration (12%, 13%, 14%, 15%, 16%, 17%, 18% and 19%). The optimum conditions were obtained by using 15% egg white adhesive, namely with a water content of 8%, ash content of 7%, volatile matter content of 1.5%, and bound carbon content of 83.5% which met SNI 01-6235-2000 and a calorific value of 4194.03 cal/g, and a combustion rate of 0.140 g/minute.

Abstract

Methyl ester co-solvent will accelerate the reaction without the need for a separation stage at the end of the reaction. The study aims to determine the effect of FAME co-solvent concentration and time of reaction on the methyl ester produced in the interesterification reaction of palm oil into biodiesel with methyl ester co-solvent. The weight of the oil used was 250 g, the mole ratio of oil: methyl acetate = 1:6, the temperature was 60oC, the concentration of the co-solvent (0 - 20%), the reaction time (30-90 min), the catalyst KOH 1% and the stirring speed was 800 rpm. The oil, methyl acetate and catalyst were placed in a three-necked flask and the reaction was carried out according to the operating conditions. The optimum conditions were obtained in the palm oil interesterification process with a FAME co-solvent concentration of 20% and a time of reaction of 30 min with  a methyl ester concentration of 61,413 mg/L and an acid value of 0.28 mg KOH/g which met SNI 7182-2015. The research revealed a biodiesel production process with fewer steps, faster reaction times, higher yields, and product physical properties that meet standards. It is hoped that this process can be implemented at a pilot plant scale, bringing the selling price of biodiesel closer to that of diesel fuel.

Abstract

In the dry weight of papaya seed oil contains up to 30%, so the potential to be used as raw material for biodiesel. Transesterification in situ is a simple step to produce biodiesel that is by eliminating extraction process and refining of oil so it can save on production costs and give satisfactory results. The reaction of one phase can be formed by adding a co-solvent to increase the solubility of oils. N-hexane is a co-solvent that is best because it is inexpensive, non-reactive and low boiling point (68°C) so that it can be separated by co-distillation with methanol. Microwave can propagate passed through the liquid so that the heating process will take place more effectively and the process of making biodiesel can be made shorter. In this study the variation of power used is 30%, 50% and 70% of 399 watts and the reaction time is 2,4,6,8 and 10 minutes. Results were analyzed by GC (Gas Chromatography). The optimum yield was 89.25% at 70% power and reaction time 8 minutes. The optimum yield has a density of 0.86 g / cm 3 and has an acid number of 0.28 mg KOH/g sample. These results have met the SNI 7182:2015.

Abstract

Minyak atsiri jahe merupakan salah satu komoditas ekspor Indonesia yang sangat potensial untuk dikembangkan. Minyak atsiri jahe banyak digunakan dalam berbagai industri, seperti industri parfum, kosmetik, essence, farmasi dan flavoring agent. Mutu minyak atsiri yang rendah merupakan kendala mengapa minyak atsiri jahe Indonesia kurang laku di pasaran luar negeri. Penelitian ini bertujuan untuk mempelajari pengaruh jenis jahe (jahe gajah, jahe emprit dan jahe merah) serta metode destilasi (distilasi air dan distilasi uap-air) untuk mendapatkan minyak jahe dengan kualitas yang baik. Penelitian dilakukan dengan pengecilan ukuran jahe yang telah dibersihkan, pengeringan irisan jahe dan proses distilasi. Minyak hasil distilasi yang telah dipisahkan kemudian dianalisa. Dari hasil analisa dan perhitungan menunjukkan bahwa setiap jenis jahe mempunyai komposisi dan kandungan minyak jahe yang berbeda. Jahe merah mempunyai rendemen terbesar yaitu 0,342 % dengan kandungan minyak (sineol) sebesar 11,39 %. Metode penyulingan mempengaruhi rendemen dan kualitas minyak jahe yang dihasilkan, dimana metode yang paling baik adalah metode penyulingan air dan uap. Jahe merah mempunyai kualitas minyak jahe terbaik yaitu massa jenis 0,8828 g/mL, bilangan asam 1,136 mg KOH/g, bilangan ester 7,980 mg KOH/g serta memenuhi standart SNI 06-1312-1998.

Abstract

Proses transesterifikasi dalam pembuatan biodiesel kurang efektif karena ada tahap pemisahan produk samping gliserol. Proses interesterifikasi lebih efektif karena produk samping triasetin tidak perlu dipisahkan dan berfungsi sebagai antioksidan pada biodiesel. Waktu reaksi dan konsentrasi katalis merupakan factor yang sangat penting untuk terjadinya suatu reaksi. Menyelidiki bagaimana reaksi interesterifikasi antara metil asetat dan minyak kelapa sawit dipengaruhi oleh waktu reaksi dan konsentrasi katalis NaOH merupakan tujuan utama penelitian ini. Parameter-parameter berikut digunakan: 250 g minyak, perbandingan molar metil asetat terhadap minyak 1:6, kecepatan pengadukan 400 rpm, konsentrasi katalis NaOH berkisar antara 0,25 hingga 0,75 persen, suhu reaksi 60 derajat Celsius, dan durasi reaksi 15 hingga 75 menit. Reaksi antara minyak, metil asetat, dan NaOH dilakukan dalam labu tiga leher sesuai dengan parameter operasi. Setelah melewati corong pemisah, hasil reaksi dicuci dengan air suling untuk menyesuaikan pH-nya menjadi netral. Setelah mendestilasi fase atas, bahan sisa dianalisis dengan kromatografi gas (GC) untuk pengujian konsentrasi dan sifat fisik. Pada periode reaksi 60 menit dengan katalis NaOH 0,5%, proses interesterifikasi minyak kelapa sawit ditemukan optimal, menghasilkan 68.504 mg/L FAME, nilai asam 0,224 mg KOH/g, serta densitas 0,888 g/mL, selaras SNI 7182:2015.
