Abstract

Leather is a product obtained from the conversion process of raw skin/hide into leather. The process generate a number of wastes with a high pollutant content, especially waste water. The waste contributes to the formation of carbon emission. Awareness on environmental sustainability also requires the industry to improve its production system to make it more eco-friendly. Improvements will increase production and the industry reputation. Before making improvements to the production system, it is necessary to carry out an analysis related to the carbon emissions produced in producing a product. The objectives of this study were to calculate carbon emission (carbon footprint) that generates in the leather tannery process and to give alternative strategy for the environmental improvement. The research used primary data and secondary data. This research was carried out with the processes identification, carbon emission sources identification, an analysis of the carbon emission potential amount, and a study of strategies to minimize carbon formation in the tannery. The results of the analysis showed that electricity and wastewater were sources of carbon in the production process of leather. The total of carbon emission formed in the leather tanning process was 1,692.17 kg CO2 eq per batch, where wastewater contributed more than electricity. Further analysis showed that 1 m2 of leather produced 8.08 kg CO2 eq of carbon. The strategies that can be taken to reduce carbon emissions are engineering processes, material substitution, and using eco-friendly materials. Keywords: carbon footprint, leather, tannery

Abstract

In the current era, the increase in infrastructure development correlate with the increased use of concrete. This is because currently, many buildings used concrete. However, concrete is prone to damage due to incomplete processes, for example cracking. Based on several studies that have been reviewed, these problems can be minimized by using silica, both micro, and nano sizes. In general, the silica used comes from quartz sand in the concrete mixture that has been studied. On the one hand, the use of silica is beneficial in the manufacture of concrete, but on the other hand it has a negative impact on the environment. If this is not done prevention, the environment will be more damaged. Therefore, this article looks at the potential of silica from rice husk ash and looks    at    the    characteristics    of    concrete    with     silica     addition     from     quartz     sand.

Abstract

The objective of this study was to evaluate the pelt and wastewater characteristics after deliming process in an acid condition by tartaric acid, also wet blue properties that were formed. Various observed variables were the dose of tartaric acid, pelt thickness, calcium content, physical and chemical properties of wet blue, such as tensile strength, tear strength, elongation, shrinkage temperature, and chrome oxide content, as well as the pollutants content of wastewater as chemical oxygen demand (COD), biological oxygen demand (BOD), total suspended solid (TSS), and total dissolve solid (TDS). The experiment used a completely randomized design with a factorial arrangement. The first factor was pH variables consisted of 3 levels, i.e., 4, 5, and 6 in the final deliming solution. The second factor was the deliming time consisted of 3 levels, i.e., 45 min, 60 min, and 75 min. Data were analyzed using Analysis of Variance (ANOVA) and then Duncan’s Multiple Range Test (DMRT). The results showed that deliming for 60 min and the pH of 5 at the end of the solution was the best treatment to remove calcium content in the pelt and reduce the thickness of pelt. It did not affect the physical and chemical quality, such as tensile strength, tear strength, elongation at break, and shrinkage temperature of the wet blue produced. Also, the quality of wastewater produced was better than the use of ammonium sulfate as a deliming agent. It can be concluded that the use of tartaric acid as pH regulator of deliming stage at pH 5 for 60 min can be used as an alternative deliming agent to substitute ammonium sulfate.

Abstract

Bating is one of the processes in leather production. This process is generally performed under slightly alkaline conditions, but it can also be done under acidic conditions. Rhizopus oligosporus is categorized as a microorganism that can synthesize acidic enzymes optimally in acidic conditions. This study aimed to evaluate the effect of the bating process using acid protease from R. oligosporus on the leather qualities tanned by chromium sulfate. The study used a completely randomized design where crude enzyme activity (0, 2.5, 5, 7.5, and 10 U mL-1) was a single treatment as an experimental design. Data were analyzed using ANOVA and furtherly tested using Duncan. The results show that the protease synthesized from R. oligosporus is potential to be used as a bating agent. The treatment with 2.5 U mL-1 activity was the best treatment in this study to improve leather (wet blue) properties like shrinkage temperature, ash content, and chrome oxide content. The quality of wet blue produced was better than that produced with conventional treatments. It can be concluded that the enzyme activity of 2.5 U mL-1 could be used as a bating-agent alternative in the acid bating stage.

Abstract

Kerutan merupakan salah satu tanda penuaan dini yang terjadi pada kulit. Hal tersebut disebabkan oleh menurunnya kandungan kolagen yang terdapat pada kulit.. Kolagen merupakan dasar dari jaringan ikat dan mengikat sel-sel dalam jaringan serta membentuk kerangka tubuh. Kolagen berpotensi untuk dijadikan berbagai jenis porduk. Banyak produk makanan, minuman, farmasi dan kosmetik memanfaatkan kolagen karena aktivitasnya yang dapat mencegah proses penuaan. Serat kolagen terdiri dari tiga rantai polipeptida yang saling berhubungan, masing-masing tersusun dalam struktur khusus triple helix. Kolagen adalah protein berserat dengan unit yang selalu berulang yakni glisin, prolin, dan hidroksiprolin. Serat kolagen dihubungkan dengan ikatan hidrogen. Minuman fungsional yang mengandung kolagen dapat mengurangi kekeringan kulit, mengurangi keriput, meningkatkan kepadatan kolagen dan kekuatan kulit yang signifikan. Minuman kolagen dapat menghambat penuaan dengan menghambat reactive oxygen species (ROS) dan memfasilitasi pembentukan ECM, meningkatkan aktivitas mitokondria dan meningkatkan ekspresi gen untuk memperbanyak protein, memperbaiki ketidakcocokan DNA (MMR) dan perbaikan eksisi dasar (BER).

Abstract

Chicken and duck eggs are highly nutritious food products that are popular among the Indonesian community. However, their perishable nature leads to a decline in quality if not further processed. The salting process is a simple preservation method that can also enhance the flavor of salted egg products. To produce salted egg products with high organoleptic quality preference, a combination of Analytical Hierarchy Process (AHP) and Simple Additive Weighting (SAW) is implemented as a quality decision-making method based on: (1) the experts viewpoints on the importance level of organoleptic criteria, and (2) the scores of organoleptic tests for the criteria of texture, taste, and appearance. In this study, chicken and duck eggs were processed into salted eggs using a salting mixture made of a blend of scouring ash and table salt with a mass ratio of 5:4 and 5:6, resulting in product combinations coded as CE-5/4, CE-5/6, DE-5/4, and DE-5/6. Data processing results on the importance level from the experts viewpoints using the AHP method resulted that the criteria for texture, taste, and aroma had final priority weights of 0.244, 0.617, and 0.139, respectively. Final decision-making using the SAW method indicated that the highest to lowest final preference scores were obtained by products CE-5/4, DE-5/4, DE-5/6, and CE-5/6, with the final preference scores of 0.979, 0.963, 0.931, and 0.906, respectively. The results demonstrated that AHP and SAW were successfully implemented to assist in making decisions regarding the quality of salted egg products based on their organoleptic characteristics.   Keywords: salted egg, organoleptic, decision-making, AHP, SAW
