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.

Abstract

Bioethanol is produced by the fermentation of glucose (sugar) from natural sources using microorganisms. Prior isolate IS258 was distinguished as a potential yeast to produce bioethanol. This study aimed to determine the optimum fermentation temperature and compare fermentation media using IS258 isolate as a starter to produce ethanol optimally. This study conducted four fermentation temperature treatments (24, 26, 28, and 30 °C) and compared two fermentation media, namely, PYG (Peptone Yeast Glucose) media used in the lab for probed, and coconut sap in traditional fermentation. There are diverse stages that were conducted in this research, namely cell rejuvenation, propagation of the IS258 isolate, fermentation, distillation, and calculation of tested variables. The optimum temperature of fermentation acquires at 28 °C with a difference of total dissolved solids 12,4 ⸰brix, which attains 104,13 ml of accumulated ethanol. During the comparison test of fermentation media, the optimum PYG media produced the highest total ethanol, which was 105,46 ml. The difference in the total yield of ethanol is affected by the differences in the nutrients of carbon (C) and nitrogen (N) elements contained between the media, which was lacking in coconut sap
