The purpose of this study is to analyze the process of performance evaluation of vendors especially in the vendor that provides a raw material for pressure vessel plate made of carbon steel. As for the evaluation process undertaken by PT. XYZ through performance indicators (KPI) where an evaluation that applied a focus on quality and delivery. In this study, researchers used the designation criteria vendor performance indicator (VPI) where the criteria used consist of quality, cost, delivery, flexibility and responsiveness (QCDFR). The methods used in the analysis process that is Analytical Hierarchy Process (AHP). Data collecting directionally by questionnaire method among 3 respondents on the procurement department that know the performance of the vendors over the years. The result showed that PT. RE has the best performance among the four vendors, as known PT.SS, PT. ST, PT. CH and PT. UN within value 0.540; The vendor with lowest performance owned by PT.CH within value 0.034.Keyword : Analytical Hierarchy Process (AHP), vendor performance indicator (vpi), plate pressure vessel, vendor performance evaluation Penelitian ini bertujuan untuk menganalisis proses evaluasi kinerja vendor khususnya pada vendor yang mensupplai bahan baku plate pressure vessel berbahan carbon steel.

Background. Starch and its products are used in a variety of ways for both the food and nonfood industries. A factorial experiment is carried out with two factors to explain the behavior of the percentage of starch, where the factors correspond to the extraction method and to the raw material. Method. Three methods were used in triplicate: the first followed the official technique of the Association of Official Analytical Chemists (AOAC), to perform acid hydrolysis and quantification of starch by Titulation; the second method involved the colorful reaction with iodine using the UV equipment to measure the absorbance and calculate the percentage of starch; as a third method the FTIR was used, through which the concentration of the starch was calculated by the area under the curve obtained from the spectrum. Results. there is an effect of both the method and the raw material on the percentage of starch, while there was no effect of the interaction; the Tukey test indicates that the highest average percentage of extraction occurs with the extraction method by Titulation and with the starch of Manihot esculenta. Conclusion. It is used as raw material. The method of quantification of starch by UV-VIS spectroscopy was the best for the study samples because it presented less deviation in relation to the FTIR and Titulation methods.

This paper aims to assess the technical, economic, and financial viability of cultivation of mushroom from coffee waste and pulp. The raw material characteristics and technical aspects were analyzed. In techno economic analysis, the investment is defined, and the financing of the project were explained. It is believed that production of mushroom from coffee waste and pulp is feasible as well as profitable in San Salvador. Use of coffee waste in the production of mushroom will prevent its damping in landfills and thus be friendly to environment as well.

Corncob is usually disposed of directly as waste, creating problems in the environment, while it can be converted into valuable materials. This research aimed to evaluate the literature review on briquette production from agricultural waste (using non-binder and cold press with a binder) and the current works on techno-economic analysis, to propose an optimal design for the production of briquette from corncob waste, and to perform a techno-economic analysis based on the selected optimal processing method. The engineering perspective based on stoichiometry and mass balance showed the potential corncob briquette manufacture in both home and large scales due to the possible use of inexpensive and commercially available equipment and raw materials. The economic perspective [based on several economic evaluation factors (i.e., gross profit margin, payback period, break-even point, cumulative net present value, return of investment, internal rate return, and profitability index) under ideal and non-ideal conditions by considering internal (i.e., sales, raw materials, utilities, and variable cost) and external aspects (i.e., tax)] confirmed the prospective development of the project in the large-scale production with a lifetime of more than 18 years. The main issue in the project is the raw material (i.e. tapioca flour), giving the most impact on the project’s feasibility. Even in severe conditions, the project is feasible. The great endurance was also confirmed in the case of a higher tax rate. This study demonstrates the importance of producing corncob-based briquettes for improving the economic value and giving alternatives for problem solvers in the utilization of agricultural waste.

After liberalisation established new relations in Slovak economy, it seemed that problems of agricultural companies differentiation would disappear. But the economic results of our companies confirm the existence of this problem. In the pre-reform period, agricultural production intensity was considered as a main factor of economic differentiation. Transformation of economy after 1990 changed the methodological approach to business performance evaluation. The interest was shifted towards the value evaluation comparing businesses with regard to financial indicators. These methods enable to classify enterprises into bonity classes and to set their sequence according to performance.

Salah satu faktor yang mempengaruhi kinerja perusahaan adalah keberadaan supplier yang berperan sebagai pemasok kebutuhan atau penyedia bahan baku. PT Masscom Graphy Semarang merupakan perusahaan percetakan yang telah menjalin kerjasama dengan beberapa supplier untuk menjamin kelangsungan produksinya. Oleh karena itu evaluasi kinerja supplier sangat penting dilakukan oleh perusahaan untuk mendapatkan supplier yang handal dalam memasok bahan baku. Tujuan dalam penelitian ini adalah mengidentifikasi kriteria evaluasi kinerja supplier dan penentuan prioritas supplier yang sesuai dengan kebutuhan perusahaan, dan menentukan urutan prioritas supplier untuk bahan baku utama cetak koran. Terdapat 17 subkriteria yang digunakan dalam evaluasi kinerja supplier dan penentuan prioritas supplier. Metode Analytical Network Process (ANP) dapat dijadikan alternatif untuk suatu permasalahan yang memiliki banyak subkriteria yang saling berkaitan dalam pengambilan keputusan. Selanjutnya metode Technique For Orders Preference by Similarity to Ideal Solution (TOPSIS) digunakan untuk perankingan supplier. Berdasarkan pembobotan subkriteria dengan menggunakan ANP, subkriteria yang paling besar pengaruhnya dalam evaluasi supplier adalah harga penawaran sebesar 0,17227. Selanjutnya, penentuan prioritas supplier dilakukan dengan menggunakan metode TOPSIS dan didapatkan urutan supplier untuk bahan baku kertas CD roll adalah supplier A, B, C, dan D, sedangkan untuk bahan baku tinta web adalah supplier L, N, O, dan M.   ABSTRACT One of the factors that influence the company performance is the presence of suppliers which supplies raw materials. PT Masscom Graphy Semarang is a printing company which has cooperated with several suppliers to ensure continuity of production. Therefore,  supplier performance evaluation conducted by the company is very important to obtain a reliable supplier in the supply of raw materials. The purpose of this research was to identify the supplier performance evaluation criteria and priorities of suppliers in accordance with the company's needs, and determined the priority order of the main raw material supplier for newspaper print. There was 17 sub-criteria used in evaluating the performance of suppliers and prioritization of suppliers. Analytical Network Process (ANP) can be used as an alternative to solve a problem that had many interrelated sub-criteria or influence in decision making. Furthermore, the method Technique For Orders Preference by Similarity to Ideal Solution (TOPSIS) was used for ranking suppliers. Based on the weighted sub-criteria by using ANP, the most influence subcriteria in determining the priority of suppliers offering price of 0.17227. Furthermore, to the supplier prioritization was done by using the TOPSIS method and obtained the order suppliers for raw materials paper roll was a supplier A, B, C, and D, while the raw material for the ink web was a supplier of L, N, O and M.
