Cleaner degreasing of sheepskins by the Yarrowia lipolytica LIP2 lipase as a chemical-free alternative in leather industry

An alternative strategy to reduce the trade balance deficit simultaneously to increase the net foreign exchange is the import-substitution for raw materials used to produce an export goods. This paper proposes an import substitution study on footwear products that have a dependency on imported raw materials by 70 percent, with the largest composition being leather raw materials by 67 percent. This paper analyzes the relationship between subsidies on the leather industry to leather import-substitution, multiplier effect to footwear sector, and Indonesia trade balance. Author make use of simulation the on Input-Output 2010 table and Computable General Equilibrium (CGE) Model. The simulation shows 100 billion subsidies on the leather sector, lead for the substitution-import of leather by 7,94 million rupiah, increase the net export foreign exchange by 1.1 billion rupiah of the footwear sector, and for overall, increase Indonesia trade balance deficit by 68 billion rupiah. Keywords: Computable General Equilibrium, footwear, leather, net foreign exchange, subsidy.ABSTRAK: Salah satu terobosan untuk mengurangi defisit neraca perdagangan dan meningkatkan nilai neto devisa ekspor adalah dengan substitusi impor bahan baku yang digunakan untuk memproduksi barang ekspor. Paper ini mengusulkan kajian substitusi impor pada produk alas kaki yang mempunyai ketergantungan bahan baku impornya sebesar 70 persen, dengan komposisi terbesar adalah bahan baku kulit sebesar 67 persen. Tujuan penelitian ini adalah untuk mengetahui dampak stimulus subsidi pada industri kulit terhadap subtitusi impor kulit, dukungan multiplier sektor kulit terhadap sektor alas kaki, serta terhadap devisa ekspor Indonesia. Penelitian ini menggunakan simulasi model Computable General Equilibrium (CGE). Hasil simulasi menunjukkan stimulus subsidi sebesar 100 milyar rupiah pada sektor kulit memberikan substitusi bahan baku kulit sebesar 7,94 juta rupiah, menaikkan devisa ekspor sektor alas kaki sebesar 1.1 miliar rupiah, serta secara keseluruhan menambah defisit neraca berjalan Indonesia sebesar 68 miliar rupiah.

The Relationship

Small and medium enterprises (SMEs) are considered as foundation stones of economic development and growth of any economy (Centobelli, Cerchione, & Esposito, 2019). Performance of SMEs is of fundamental significance for all developed as well as developing nations. Similarly, Pakistan is no exception to aforementioned fact. The economic development and growth of Pakistan depend on the performance of SMEs to a great extent. Like, most countries in the world, SMEs comprise more than 90% of total business entities in Pakistan (Degong et al., 2018; Waqas & Nawaz, 2019) and leather industry in one that is attracted by the researchers of present study. Constraints in the growth of leather industry of Pakistan include, lack of skilled human capital, rising cost of production, lack of modern-day knowledge about new products and processes, low profitability and lack of capability to penetrate into international markets, lack of market research, access to finance, intensive competitive rivalry (Khalique et al., 2011; Daily Times, 2016, Awan et al., 2019). Few studies have revealed mixed findings regarding the relationship between knowledge management and firm performance and there is abundance of literature that demonstrates the presence of significant and positive relationship between Market Orientation and Firm performance (Slater & Narver , 1995; Baker & Sinkula, 2009; Udriyah, Tham, & Azam, 2019). On the other hand, some studies have argued that there is no direct and significant relationship between Market Orientation and Firm Performance (Polat & Mutlu, 2012; Shehu & Mahmood, 2014). Moreover, keeping in view the mixed and inconclusive findings regarding the relationship between cause and effect variables, it is appropriate to introduce moderating variables that can significantly influence the relationship between independent and dependent variables as recommended by Baron and Kenny (1986). Access to Finance and Competitive Environment can be served as prospective moderators which are quite appropriately related to proposed variables of the study (Prajogo & Oke, 2016; Rogo et al., 2016; Jaworski & Kohli, 1993) which are quite appropriately related to selected variables of the study. Thus, the research problem expressed that "Access to finance and competitive environment can potentially moderates and affect the relationship between independent and dependent variables. Hence, based on the past literature and aforementioned discussion, the present study intended to examine the moderating effects of Access to Finance and Competitive Environment on the Relationship between Human Capital, Knowledge Management, Market Orientation and SMEs Performance in Leather Industry of Pakistan".

The Impact

Ultrafiltration is a promising, environment-friendly alternative to the current physicochemical-based tannery wastewater treatment. In this work, ultrafiltration was employed to treat the tanning wastewater as an upstream process of the Zero Liquid Discharge (ZLD) system in the leather industry. The filtration efficiency and fouling behaviors were analyzed to assess the impact of membrane material and operating conditions (shear rate on the membrane surface and transmembrane pressure). The models of resistance-in-series, fouling propensity, and pore blocking were used to provide a comprehensive analysis of such a process. The results show that the process efficiency is strongly dependent on the operating conditions, while the membranes of either PES or PVDF showed similar filtration performance and fouling behavior. Reversible resistance was the main obstacle for such process. Cake formation was the main pore blocking mechanism during such process, which was independent on the operating conditions and membrane materials. The increase in shear rate significantly increased the steady-state permeation flux, thus, the filtration efficiency was improved, which resulted from both the reduction in reversible resistance and the slow-down of fouling layer accumulate rate. This is the first time that the fouling behaviors of tanning wastewater ultrafiltration were comprehensively evaluated, thus providing crucial guidance for further scientific investigation and industrial application.
