Abstract

AbstrakKeselamatan kerja merupakan faktor yang tidak dapat diabaikan dalam industri proses. Salah satu lapisan proteksi yang dapat menjamin keselamatan kerja pada suatu industri adalah Safety Instrumented System (SIS). Perancangan SIS yang diatur dalam standar ANSI/ISA No. 84.00.01-2004 meliputi tahap analisis, tahap implementasi, tahap operasi, dan tahap verifikasi. Miniatur pasteurisasi di Laboratorium Manajemen Sistem Instrumentasi dan Kontrol akan dijadikan objek pembelajaran untuk memahami konsep tingkat safety serta perancangan SIS. Analisis risiko dilakukan dengan menggunakan metode Hazard and Operability Study dan Risk matrix, dan ditentukan nilai Safety Integrity Level  (SIL) untuk miniatur pasteurisasi dengan metode Risk graph. Perancangan SIS dilakukan dengan membuat kombinasi-kombinasi dari delapan konfigurasi sistem. Perhitungan dengan Fault Tree Analysis digunakan untuk mengetahui besarnya Probability of Failure on Demand average (PFDavg) yang diperlukan dalam penentuan SIL dari tiap kombinasi SIS. Rancangan terbaik dipilih berdasarkan analisis Analytical Hierarchy Process (AHP) dengan mempertimbangkan nilai PFDavg dan biaya. Penambahan SIS pada miniatur pasteurisasi menghasilkan peningkatan nilai Risk Reduction Factor (RRF) keseluruhan sistem sebesar 83 kali dibandingkan dengan sebelum penambahan SIS. Hasil dari perancangan tersebut kemudian diuji dengan menggunakan Programmable Logic Controller (PLC) Allen Bradley RS Logix 5000.

Abstract

A texture analyzer is a standard device to measure food texture properties. This study aims to develop a mini compression test machine prototype that can function as a texture analyzer with simple operation and portability. The components and materials were chosen based on: low cost, manufacturability, and availability in the local Indonesian market. The prototype dimension was 375 × 215 × 450 mm, and used a linear ball screw slider for the translation movement with a 200 mm effective sliding distance. For obtaining the compression load, a 10 kg load cell was used, and it was replaceable by a load cell with a lower capacity if a higher measurement accuracy was required. After calibration, the linear vertical displacement and load cell had ±0.1 mm and ±1 g of accuracy, respectively. The prototype was tested to measure the texture properties of potato chops. As a result, the machine could successfully measure the load and displacement data and detect a crack phenomenon, verifying its usability as a food texture analyzer.

Abstract

Healthcare facilities are very important for sustainable rural regions in developing countries. The Republic of Rwanda, in central east Africa, suffered massive social conflict in 1994 between the Hutu and Tutsi. Furthermore the health problem happened in Burera District because of lack of a proper district hospital. Therefore, in January 2011, the Rwandan Ministry of Health and Partners in Health (PIH) opened the 140-bed Butaro Hospital in the Burera District of Rwanda. The paper-based research was conducted based on hospital’s architecture of Hatmoko, et.al. (2010). Analysis was made with based on the secondary data of Butaro Hospital. Lastly, primary data gathering would be conducted if the funding allowed. The Butaro Hospital was an affordable solution for healthcare problems in rural regions of the developing countries, especially the infectious diseases (such as: HIV, malaria, tuberculosis, nose-ear-and-throat disease). Sustainable innovative solutions for minimum infection were implemented such as: external corridors, large-radius-low-speed fans (with diameters of 24 feet), high-louvered windows, germicidal UV lights, and non-permeable-continuous flooring. The construction of the hospital also would reduce the impact of political crisis in 1994. The project created 4,000 jobs for local craftsmen and local residents. They were initially trained for manual excavation, construction, and project management, before involving in the hospital construction. Therefore, the Butaro Hospital supported the smart regions of Burera area.Keywords: Sustainable and affordable hospital, participatory design, local material

Abstract

This research delves into the pivotal role of quality management in sustaining organic vegetable production, underscoring its profound connection to consumer satisfaction and subsequent impact on purchasing decisions. Within the organic market, predominantly catering to the upper to middle-class demographic in Batu, East Java, Indonesia, consumer preferences dictate heightened product specifications and, consequently, necessitate a focus on quality. To fortify market presence, this study advocates for the direct involvement of organic farmers throughout the entire production-to-marketing continuum, transforming them into not just cultivators but entrepreneurs. In the face of escalating competition, product quality emerges as a paramount subsystem requiring prioritization. The study employs the quality function method for planning and developing pertinent organic vegetable products aligned with consumer interests, identifying areas for improvement. The primary objective is to ascertain consumer demands and devise corrective measures to augment satisfaction. Employing the online survey method, participants were limited to consumers who had purchased organic vegetable products from Batu-based farmers in East Java at least twice. Analyzing the data revealed that consumer prioritized quality attributes encompassed vegetable cleanliness, product pricing, and ease of accessibility. Notably, technical interventions such as the implementation of Good Handling Practices, Internal Control System (ICS), and enhancing service quality during organic vegetable cultivation significantly influenced consumer interest attributes, fostering heightened satisfaction. This study contributes valuable insights for organic farmers and stakeholders seeking to optimize product quality in response to evolving consumer demands.
