Abstract

Biogas production from lignocellulosic biomass has gained attention in the development of renewable fuels. Corn stover belongs to lignocellulosic biomass. Pretreatment is needed to help the digestion of biomass due to its lignocellulosic recalcitrance. This study aims to compare the different types of acids for enhancing biogas production. The experiment was carried out in a 1 L batch digester at room temperature with different acids of HCl, H2SO4, and C2H2O4 at concentrations of 0%, 5%, 10%, and 15%. The acids pretreatment was performed for 24 hr. Results show that pretreatment of C2H2O4 has a positive impact on increasing biogas yield. The highest cumulative yield of 580.8 mL/gVS is obtained at 15% C2H2O4. The increase in acid concentrations decreases the initial pH value. The pH value below 6 reduces biogas yield.

Abstract

Biogas has become an alternative fuel to reduce the lack of fossil fuel. Biogas can be produced from organic wastes such as corn stover. Corn stover is a typical lignocellulosic biomass and contains a total solid (TS) content higher of 15%. Biogas production was conducted by solid-state anaerobic digestion with addition co-digestion of food waste. Co-digestion is useful to help the digestion of corn stover. The purposes of this study were to investigate the effect of the percentage of food waste, volatile solid (VS) reduction, and kinetic model on biogas production from corn stover. Results showed that food waste had a significant effect on biogas yield (p < 0.05). The highest biogas yield of 584.49 mL g-1 VS-1 and the highest VS reduction of 40% was obtained at food waste of 20%. The kinetic model of biogas production from corn stover and food waste followed the first-order kinetic model.

Abstract

Banana peels belong to lignocellulosic substrates, which can be used as raw material for bioethanol. Yeast plays an essential role in bioethanol fermentation. The study aims to compare ethanol yield using two different yeasts: Saccharomyces cerevisiae and Rhizopus oryzae, with yeast concentrations of 2, 3, and 5 g/L. The fermentation is run at room temperature for 120 hours. Results show that R. oryzae generates higher ethanol compared to the yeast of S. cerevisiae. Yeast of 2 g/L obtains the highest yield of ethanol. Yeast concentrations do not affect bioethanol production (p > 0.05).

Abstract

Pineapple peel extract can be used for manufacturing organic fertilizer due to its high content of carbohydrates, protein, and sugar. The study aimed to find the effect of pineapple peel extract on fertilizer nutrients and the growth of cayenne pepper. The experiment employed an experimental method with a Randomized Block Design consisting of three combination pineapple extract treatments. The experiment was performed in 5 L of plastic containers for 15 days. The result showed that pineapple peel extract significantly affected fertilizer nutrients and the growth of cayenne pepper (p < 0.05). The extract of 2500 mL generated the highest height of the plant and the greatest number of leaves. The extract of 2000 mL produced low potassium and nitrogen. Lack of potassium and nitrogen could reduce plant height and change leaf color.

Abstract

Salted fish is a processed fishery product using salting and drying methods. Salted fish has a low moisture content because the salting process involves mass transfer by osmosis and drying involves heat transfer by solar radiation. This research aims to determine the moisture content, yield, and organoleptic tests on salted fish products using the dry salting method with varying salt concentrations of 10%, 20%, and 30%. The results of this study showed that the moisture content in each sample with a salt concentration of 10% (sample 1), 20% (sample 2), and 30% (sample 3) experienced a decrease in moisture content with the length of drying time for the fish. The lowest moisture content of salted fish in sample 3 with a salt concentration of 30%, was 6%. The longer the drying time for the fish and the higher the salt concentration in the fish, the lower the yield figures for each sample with concentrations of 10%, 20%, and 30%. In sample 1 the yield value obtained was 3% with a time of 414 hours, sample 2 was 3% with a time of 300 hours and in sample 3 the yield value was 3% with a time of 72 hours. For the organoleptic test results, the appearance aspect of sample 3 with a salt concentration of 30%, was highly favored by the panelists with an average value of (8.0); for the odor aspect of sample 1 with a salt concentration of 10%, the panelists liked it very much, obtaining a mean value of (8.3); For the taste and texture aspects, sample 3 got a mean score of 8.1 and 8.0 in the very like category. Meanwhile, for the fungal aspect in samples 1,2, and 3, the average value was 8.0, with the category of really liking the quality specifications, there was no fungus. The Salted fish products in this research are by the SNI standard no. SNI 8273:2016 concerning the maximum moisture content of salted fish of 40% and SNI no. 01-2346-2006 concerning the standard minimum organoleptic test value of least 7. Kata kunci:  salted fish, moisture content, yield   Ikan asin merupakan olahan hasil perikanan dengan menggunakan metode penggaraman dan pengeringan. Ikan asin mempunyai kadar air yang rendah karena proses penggaraman melibatkan perpindahan massa secara osmosis dan pengeringan melibatkan perpindahan panas dengan radiasi matahari. Penelitian ini bertujuan untuk mengetahui kadar air, rendemen dan uji organoleptik pada produk ikan asin menggunakan metode penggaraman kering dengan variasi konsentrasi garam 10%, 20%, dan 30%. Hasil dari penelitian ini menunjukkan bahwa kadar air pada masing-masing sampel dengan konsentrasi garam 10% (sampel 1), 20% (sampel 2) dan 30% (sampel 3) mengalami penurunan kadar air seiring lamanya waktu pengeringan pada ikan. Kadar air terendah ikan asin pada sampel 3 dengan konsentasi garam 30% yaitu sebesar 6%. Semakin lama waktu pengeringan ikan dan tingginya konsentrasi garam pada ikan, maka angka rendemen pada masing-masing sampel dengan konsentrasi 10%, 20% dan 30% pun semakin rendah. Pada sampel 1 nilai rendemen yang didapatkan adalah 3% dengan lama waktu 414 jam, sampel 2 pun 3% dengan lama waktu 300 jam, dan pada sampel 3 memiliki nilai rendemen 3% dengan lama waktu 72 jam. Untuk hasil pengujian organoleptik, pada aspek kenampakan sampel 3 dengan konsentrasi garam sebesar 30% sangat disukai panelis dengan nilai rata-rata (8,0); untuk aspek bau sampel 1 dengan konsentrasi garam sebesar 10% sangat disukai panelis dengan memperoleh nilai rerata (8,3); untuk aspek rasa dan tekstur sampel 3 endapatkan nilai rerata 8,1 dan 8,0 dengan kategori sangat suka. Sedangkan untuk aspek jamur pada sampel 1,2 dan 3 memiliki nilai rerata 8,0 dengan kategori sangat suka dengan spesifikasi mutu tidak terdapat adanya jamur. Produk Ikan Asin pada penelitian ini telah sesuai dengan standar SNI no SNI 8273: 2016 tentang kadar air ikan asin maksimum 40% dan SNI no 01-2346-2006 tentang standar nilai minimum pengujian organoleptik minimal 7.

Abstract

Sumber energi terbarukan perlu terus dikembangkan untuk menekan ketersediaan bahan bakar fosil yang sudah semakin menipis. Biogas merupakan salah satu energi alternatif dengan memanfaatkan limbah organik seperti kotoran sapi. Pengolahan kotoran sapi sebagai bahan baku biogas dapat menggunakan biodigester tipe kontinyu dan tipe batch. Tujuan dari penelitian ini adalah membandingkan volume biogas menggunakan biodigester kontinyu dan biodigester batch. Metode penelitian terdiri dari studi literatur tentang produksi biogas yang menggunakan biodigester kontinyu dan biodigester batch. Biodigester kontinyu selalu berisi 80% umpan dari volume total (50 L) dan 20% sisanya sebagai ruang gas. Biodigester tipe batch kapasitas 220 L memiliki komposisi kotoran sapi dan rumput gajah sebesar 25 kg : 25 kg dengan penambahan air 100 liter. Produksi biogas dilakukan selama 70 hari. Hasil penelitian menunjukkan bahwa biodigester kontinyu menghasilkan volume biogas total 17,520 L dan kandungan CH4 51,37%, sedangkan untuk biodigester batch menghasilkan volume biogas total 66,484 L dan kandungan CH4 31,37%. Uji nyala untuk biodigester kontinyu menunjukkan bahwa setelah hari ke-12 nyala api berwarna biru dan menyembur tetapi pada biodigester batch tidak menghasilkan nyala api karena kadar CH4 kurang dari 45%. Biodigester tipe kontinyu dengan kapasitas 50 L menghasilkan volume biogas lebih tinggi dibandingkan dengan tipe batch yang berkapasitas 220 L.
