Abstract

Packaging is one of the important aspects of a product’s identity. The good and adorable packaging can increase product competitiveness because it gives a perception to the customers of good quality products. Therefore, a good packaging display is necessary so that packaging quality inspection is very important. Automated defect detection can help to reduce human error in the inspection process. Convolutional Neural Network (CNN) is an approach that can be used to detect and classify a packaging condition. This paper presents an experiment that compares 5 network models, i.e. ShuffleNet, GoogLeNet, ResNet18, ResNet50, and Resnet101, each network given the same parameters. The dataset is an image of cans packaging which is divided into 3 classifications, No Defect, Minor Defect, and Major Defect. The experimental result shows that network architecture models of ResNet50 and ResNet101 provided the best result for cans defect classification than the other network models, with 95,56% for testing accuracy. The five models have the testing accuracy above 90%, so it can be concluded that all network models are ideal for detecting the packaging defect and defect classification for the cans product.

Abstract

In advance, the lean concept was used and applicated for big manufacturing industry. However, the lean concept used widely for all kinds of industry in the world. The improvement practice as lean and JIT also used for small industry (SMEs) in any countries which have implemented lean. The SMEs which have implemented lean showed any improvement, as the increasing of efficiency and flexibility, clear of communication and close with the Customers so the response and feedback are quicker and the costs are lower. The lean assessment tools used to value the effectiveness and the efficiency from lean implementation in the certain industry. The development of lean assessment tool for SMEs done by considering the difference between SMEs characteristic with industry a big scale. Have been many studies development of lean assessment to measure lean implementation in manufacturing industry and service generally without considered the size of his industry. However there are just a few development of lean assessment tools study that specific to measure the implementation lean manufacturing on SMEs. Therefore, this study aims to collect and compare the dimensions and indicators of the Lean Assessment Tool from several countries that are suitable for use in manufacture SMEs in Indonesia.

Abstract

Procurement is one of activity of government institution. ULP Bontang as a procurement unit is a part of Bappeda Bontang. Due to importance of procurement process, ULP Bontang needs to manage its risks by identifying, analyzing and controlling potential risk that may impedes ULP objectives. All goverment institution refer to a Internal Government Controlling System which called by Sistem Pengendalian Intern Pemerintah (SPIP) for conducting its risk management. Since there are several part of SPIP is not applicable in ULP Bontang. Therefore in this research, SPIP is modified based on ISO 31000 framework. Moreover, Delphi method is utilized to identiry riks involving five experts and established 23 potential risk in ULP Bontang. The modifications were also made in developing of severity and probability tables corresponding to the conditions of ULP Bontang. The formulation of mitigation recommendation concerned by very high potential risks. The mitigation for risk number (12) ULP Bontang office is not representative are securing ULP office using fingerprint device so only authorized personel allowed to enter the office. The cost required for this mitigation is about Rp 30.000.000 and Rp 32.000.000 for CCTV installation and evacuation route sign and also ULP needs to partnership with other institution to securing ULP Bontang member.

Abstract

Permasalahan yang dihadapi dalam pemenuhan kebutuhan gula nasional saat ini antara lain adalah permasalahan on-farm, off-farm yang membutuhkan kesadaran masing-masing stakeholder industri gula. Stakeholder utama dalam industri gula adalah petani tebu dan pabrik gula yang dalam penelitian ini adalah PG. Djatiroto. Semakin banyak stakeholder, maka proses bisnis di dalamnya akan semakin kompleks. Oleh karenanya, dibutuhkan pengelolaan risiko supply chain untuk koordinasi dan mengelola aktivitas dari masing-masing aktivitas bisnis supaya tujuan utama berupa peningkatan produktivitas gula bisa tercapai. Langkah awal yang harus dilakukan adalah identifikasi risiko. Dalam penelitian ini digunakan metode Delphi karena metode Delphi menyediakan alternatif yang lebih handal dan efisien untuk memecahkan masalah dengan ketidakpastian yang tinggi dan menguatkan cara brainstorming dan wawancara expert Delphi. Responden dalam metode Delphi terdiri dari 2 stakeholder utama dalam supply chain industri gula, yaitu PG. Djatiroto dan petani tebu.
