Supply chain risk management in newspaper company: House of risk approach

Abstract: In the supply chain (SC) of newspapers, the printing company is the main entity that has several processes, i.e. procure raw materials, print plate and newspapers, and also distribute newspaper to consumers. The existing risks in the newspaper printing company are quite high. A wide range of disturbances or risks needs to be identified to map out the characteristics of the risk sources that will impact on the performance of the supply chain. Therefore, the printing companies need to manage their supply chain risk of the five major SC processes (such as plan, source, deliver, make, and return). In a case study of a newspaper company in Surakarta, the company have not implemented a risk management process that affects the company. This study is aimed to map the risks in the printing company and formulate risk mitigation alternatives to mitigate the risks. The house of risk (HOR) method was chosen to select a set of proactive actions deemed cost-effective in managing SC Risks in the newspaper company. The model consisting of two stages, the first stage (HOR1) was done by identifying risk, risk causing agents and then measured the severity and occurrences to calculate the Aggregate Risk Priority (ARP) value. The second stage (HOR2) is intended to formulate and prioritize the action of mitigation that the company should pursue to reduce the probability of risk agents to occur. The result shows that the innovative model of HOR in Newspaper Company was presented. There are 24 risk events, 20 causing agents and two priority risks in HOR1. The HOR 2 was proposed 9 ranks of mitigation strategy for priority risk agents, from the easiest to the hardest strategy for the company to implement it.

Bioethanol Production By Utilizing Cassava Peels Waste Through Enzymatic And Microbiological Hydrolysis

Abstract: Cassava peels waste contains, cellulose which is quite high at 43.626%, this is a potential candidate as a raw for bioethanol production. The purpose of this study was to determine the performance of the enzymatic hydrolysis, microbiological (Effective microbe) and fermentation in cassava peel waste is known from the results of quantitative measurement of multiple ethanol parameters (DNS Test, pH, ethanol concentration). This research was carried out in stages, the first stage is hydrolysis with completely randomized design with single factor variation of the catalyst, consisting of three levels ie cellulase enzymes, multienzyme and effective microbial EM4. The second stage is fermentation with factorial randomized block design, consisting of three groups of variations of catalyst, and has two factors: variations of fermipan levels 1, 2, 3% and the duration of fermentation, 2,4,6 days. The parameters in the test is a reducing sugar, pH and concentration of ethanol. The results showed that variation of hydrolysis treatment, fermentation time, and fermipan levels has real effect on the fermentation process. On average the highest ethanol content obtained from the treatment with multienzyme addition, with the addition of 2% fermipan levels and on the 2nd day of fermentation that is equal to 3.76%.

Dongkrek: an islamic literature and artform in madiun east java

Abstract: Dakwah refers to the spreading of Islam and its teachings through various means. Dongkrek , meanwhile, is a traditional artform with Islamic literary value that has been used as a medium for dakwah . This study seeks to describe and explore dongkrek as an artform with Islamic literary value and its use as a medium for dakwah in Madiun Regency. It is a qualitative study, which takes as its case study a dongkrek troupe from Madiun Regency. The main source of data for this study is the dongkrek performance itself; supporting data has been collected from texts and informants. Data collection involved observations, library research, and in-depth interviews with informants. For this study, data analysis was conducted using content analysis and interactive analysis. This study finds that dongkrek is an Islamic literary artform said to have been created by R. Bei Lo Prawirodipuro in 1910. It may be considered an Islamic artform as the lyrics used in performances convey Islamic teachings; it is through these lyrics that Islamic values are conveyed to audiences as a form of dakwah . It is shown that dakwah and dongkrek are complementary, ensuring both the innovativeness of dakwah and the survival of dongkrek . It may thus be said that dongkrek is both a spectator and guiding medium. Keywords: dakwah media, dongkrek , tradition, traditional performance art DONGKREK: SEBUAH SASTRA ISLAM DAN PERTUNJUKAN SENI DI MADIUN JAWA TIMUR Abstrak Dakwah adalah cara menyebarkan agama Islam dengan metode yang beragam. Dongkreng adalah salah satu bentuk kesenian tradisional yang dapat digunakan sebagai media dakwah. Penelitian ini memiliki tujuan untuk menjelaskan dan mendeskripsikan kesenian dongkrek yang digunakan sebagai media dakwah di Kabupaten Madiun. Penelitian berbentuk penelitian kualitatif dengan pendekatan studi kasus. Studi kasus dilakukan pada kelompok kesenian dongkrek yang ada di Kabupaten Madiun. Sumber data utama dalam penelitian ini adalah bentuk pementasan dongkrek. Sumber data pendukung adalah teks dan informan. Teknik pengumpulan data dilakukan dengan observasi, studi pustaka, dan wawancara mendalam dengan informan. Teknik analisis data dalam penelitian ini menggunakan content analysis dan analisis interaktif. Dari hasil penelitian ditemukan bahwa kesenian dongkrek termasuk dalam sastra Islam yang diciptakan oleh R. Bei Lo Prawirodipuro tahun 1910. Disebut kesenian sastra Islam karena dalam kesenian dongkrek terdapat lirik lagu yang memuat tentang ajaran agama Islam. Kesenian dongkrek digunakan sebagai media dakwah dengan mengajarkan syi’ar kepada masyarakat melalui pementasan seni dan budaya. Hal ini seperti yang dilakukan oleh walisongo. Hubungan antara dakwah dan dongkrek adalah saling menguntungkan yaitu pembaruan dalam bidang dakwah serta pelesarian dalam bidang budaya. Dapat dikatakan dongkrek adalah sebagai media tontonan dan tuntunan. Kata kunci: media dakwah, dongkrek, tradisi, seni pertunjukan tradisional

A parametric cost estimation model to develop prototype of electric vehicle based on activity-based costing

Abstract: Accurate estimation is still challenging for the development stage of a product due to lack information about the production process, bill of material, and detailed activity. Parametric cost estimation based on activity-based costing can be used to generate the cost information of the whole process from the design stage until development stage. This paper presents a parametric cost estimation model that links activity-based costing to enhance accuracy of estimation for developing an electric vehicle prototype. The parametric cost represents the development process of a prototype consisting of four main processes. It also presents activities, cost center, and cost driver in each process. The total cost of each cost center is formulated by mathematical equations. A prototype of the Sebelas Maret Electric Vehicle is chosen as a case study. The proposed model can be utilized to predict total cost estimation the prototype of electric vehicle. This estimation method can influence cost reduction of developmental stage.
