Abstract

Belacan depik is one of Gayo's fermented fish products, which is still rarely studied scientifically. This product is a fermented fish paste made from depik fish (Rasbora Tawarensis). Scientific studies regarding the yeast involved in the fermentation of depik fish have never been reported. This study aims to characterize and identify yeasts that have proteolytic activity. This study was designed as an exploratory laboratory study, beginning with the isolation and characterization of the yeast from belacan depik and identification molecularly. The three pure isolates Y1, Y2 and Y3 that were successfully isolated had various morphological and biochemical characteristics. Only Y2 isolate has proteolytic activity. The results of molecular recognition showed that isolate B1 was identified as Rhodotorula mucilaginosa strain IMUFRJ 52392 with 100% homology and query cover. The identification of Rhodotorula in belacan depik products indicates a certain role during fermentation. Further studies are needed regarding its role during fermentation and its potential as a biological agent in improving the quality of belacan depik.

Abstract

One of the kratom (Mitragyna speciosa Korth.) products in Kapuas Hulu is fermented kratom tea powder, produced by the enzymatic oxidation process, which is very different from the processing of black tea. Until now, there has been no research on the manufacture of fermented kratom tea powder using the black tea enzymatic oxidation method. This study aimed to determine the differences between the enzymatic oxidation method to the antioxidant activity of water extract kratom tea. The technique used in this study was a comparative method to compare the data obtained from water extract kratom tea. The treatments compared were the manufacture of fermented kratom tea powder with the enzymatic oxidation method of the Kapuas Hulu community and the enzymatic oxidation method of black tea. The parameters tested in this study consisted of phenol content, flavonoid content, alkaloid content, and antioxidant activity. The study showed that the phenol and alkaloid contents were higher in product of black tea methods (199.22 mg GAE/g and 44.73%) than Kapuas Hulu traditional methods (50.45 mg GAE/g and 40.68%). Flavonoid content was higher in Kapuas Hulu traditional methods (169.32 mg QE/g) than black tea methods (48.77 mg QE/g). The difference was found in the antioxidant activity of the water extract kratom tea produced by two different enzymatic oxidation methods. The enzymatic oxidation of the black tea method was found to higher antioxidant activity of water extract kratom tea.

Abstract

Anthracnose disease (Colletotrichum spp.) in chili can lead to low fruit quantity and quality from planting to the postharvest stage. The environmentally friendly management using chitosan (CS) is expected to suppress anthracnose disease and increase the shelf-life of chili. This study aimed to determine the effect of the chitosan-tripolyphosphate (CS-TPP) to suppress anthracnose on chili during postharvest storage through in-vitro and in-vivo assays. In the in-vitro assay, CS-TPP solution with a ratio of [5:2] and [3:1] was applied into a warm Potato Dextrose Agar (PDA) medium. It was grown by Colletotrichum pathogen, while on in vivo assay, CS-TPP was applied to chili fruit before being inoculated by the pathogen. A control treatment was prepared without CS-TPP application. Results revealed that the CS-TPP ratios affected the growth of Colletotrichum spp. at the in-vitro assay. The CS-TPP [5:2] ratio was more effective than CS-TPP [3:1] in reducing the growth of Colletotrichum spp. with the fungal inhibition of 62,65% and 55,56%, respectively, compared to the control treatment. Moreover, it also showed anthracnose disease suppression on chili fruit of 51%, and 29%, respectively, compared to control treatment at in-vivo assay. This study showed the potential use of CS-TPP as a coating application for anthracnose disease management on storage chili, however further study such as viability and longevity of formula need to be done.

Abstract

Organic coffee robusta is a leading commodity produced by farmers because it has a significant enough demand. Organic coffee robusta is sold as green beans or processed coffee roasted and ready to brew. Supply chain management is essential considering that agricultural commodities have perishable, seasonal, wide variety, and bulky limitations, thereby increasing the risk of supply chain activities. Complexity in the supply chain creates various risks that must be minimized and mitigated. This study aims to analyze the supply chain risk of organic robusta coffee and determine the risk mitigation strategy of the organic robusta coffee supply chain with a fuzzy approach. Identification and mitigation of upstream to downstream risks are needed to achieve the objectives of the organic coffee supply chain in Pasrujambe District, Lumajang Regency. Supply chain risk identification is carried out using the Fuzzy Failure Mode and Effect Analysis (FFMEA) method and determining risk mitigation strategies using the Fuzzy Analytic Hierarchy Process (FAHP) method. Both methods use expert respondents consisting of 3 farmers, 3 large collectors, and 3 experts in roastery. The results of the identification of the highest supply chain risk at the farmer level are the risk of non-uniform coffee fruit size (5.74), at the large collector level is price fluctuation (4.79), and at the roastery, the level the failure to regulate roasting temperature and time with an fuzzy risk priority number (FRPN) value of 5,26. Therefore, to minimize and mitigate these priority risks at the farmer level, increasing knowledge about organic coffee cultivation is necessary. At the large collector level, it is necessary to build institutional internalization stability, and at the roastery level, to improve the quality of the roastmaster.

Abstract

Environmental issues are a priority in the development of the kenaf fiber industry globally, because kenaf fiber is considered an environmentally friendly vegetable fiber when used as a raw material. This is revealed from the retting process which is the main process in processing the kenaf plant into kenaf dry fiber. The purpose of this study was to determine the green productivity index on the upstream side of the kenaf fiber agro-industry network by mapping green value stream mapping. Based on the research that has been done, it can be concluded that there are 6 alternatives to clean production, 4 of which can add value to the waste and 2 of them are routine activities of the kenaf fiber agroindustry. Then the results of the GVSM Current State mapping on energy of 12,753.6 Joules, water as much as 32,810.1l, material as much as 14,340 kg, waste as much as 14,860 kg, emissions of 1,584 kg, and biodiversity as much as 4,000 kg. After the alternative production is carried out, the results of the GVSM Future State mapping are 11,159.4 Joules of energy, 32,810.1l of water, 14,340 kg of materials, 1,584 kg of emissions, and 4,000 kg of biodiversity. There was a reduction in energy in the form of human power of 1,594.2 Joules which was replaced by the use of machines. The GPI Current State value in the kenaf fiber agroindustry is 0.000759 and the GPI Future State value obtained is 0.001234. This means that the production alternatives given affect the increase in IE value and decrease in EI value from the kenaf fiber agroindustry so that the GPI Future State value produced is getting better so that the impact on the environment in the kenaf fiber agroindustry is decreasing.

Abstract

Bambu muda atau rebung memiliki sumber selulosa dan berpotensi untuk produksi bioetanol. Rebung juga memiliki kandungan lignin yang rendah yaitu 0,89%, sehingga memungkinkan untuk tidak dilakukan proses pre-treatment. Rebung bambu merupakan salah satu bahan yang berpotensi untuk produksi bioetanol mengingat laju produktivitas yang tinggi yaitu 8.124 kg/ha/tahun. Tujuan dari penelitian ini adalah menganalisis data produksi bioetanol dari rebung dengan teknik SSF menggunakan konsorsium mikroba Trichoderma reesei dan Saccharomyces cerevisiae. Mikroba T. reesei digunakan untuk menghasilkan enzim selulase yang menghidrolisis selulosa menjadi gula sederhana, sedangkan S. cerevisiae digunakan untuk memproduksi bioetanol dari gula yang dihasilkan sebelumnya. Sintesis bioetanol terdiri dari dua tahap utama yaitu hidrolisis dan fermentasi. Pada penelitian sebelumnya, proses hidrolisis dan fermentasi dilakukan secara terpisah menggunakan metode SHF (Separated Hydrolysis Fermentation), sedangkan pada penelitian ini dilakukan dengan menggunakan metode SSF (Simultaneous Saccharification and Fermentation) yang diharapkan menghasilkan efisiensi substrat, Yp/s, dan laju produktivitas bioetanol yang lebih tinggi dibandingkan metode SHF. Penelitian ini dilakukan menggunakan aerasi 1 vvm dan agitasi 125 rpm selama 72 jam.  Hasil penelitian menunjukkan bahwa produksi  bioetanol tertinggi di waktu 72  jam sebesar 6,94 g/L dengan laju produktivitas bioetanol  0,08 g/L/h dan  rendemen produk (Yp/s) 0,19 g bioetanol/g substrat. Hasil penelitian ini menunjukkan bahwa rebung merupakan media yang layak untuk produksi bioetanol. Rebung memiliki kandungan selulosa yang potensial sebagai substrat untuk T. reesei dan terbukti menghasilkan bioetanol yang lebih tinggi dibandingkan teknik SHF dengan bambu pada penelitian sebelumnya.

Abstract

Red ginger contains volatile components that are essential oils. Essential oils can be obtained through the distillation method. Hydrodistillation is a method of distillation that involves providing direct contact between the materials and water at a high temperature, which is influenced by several factors, including time and the solvent feed ratio (SF ratio). This study aimed to determine the best conditions for high yields and essential oil quality using SNI No. 06-1312-1998 as a reference. The research method used was experimental research, and optimization was carried out using Response Surface Methodology (RSM) with CCD design. The treatments for distillation were time (2 hours, 4 hours, and 6 hours) and solvent feed (SF) ratio (8:1, 10:1, and 12:1). The parameters observed were yield, residual solvent content, specific gravity, refractive index, and acid number. The results showed that the time and SF ratio variables had no significant effect on the yield but had a significant effect on the residual solvent content. The optimization process resulted in a time of 6 hours and a solvent volume of 720 ml (ratio 1:12), yielding 0.14 with a residual solvent content of 3,557%. The characteristics of the essential oils produced were 0.8794 for the specific gravity, 1.473 for the refractive index, and 2.13  for the acid number. Red ginger essential oil met the requirements of SNI ginger oil on the parameters of specific gravity and refractive index.
