Abstract

The TPS Reduce, Reuse and Recycle Tenggilis Mejoyo faces a problem with waste residue levels of 58.61%, far above the ideal target of 30%. This research develops an automated waste sorting device using the Quality Function Deployment (QFD) approach to optimize the sorting process. The research methodology employs four QFD phases from Voice of Customer to production planning. A prototype measuring 40x10 cm with a conveyor speed of 10 cm/s was developed based on high-priority technical responses. Testing was conducted with 5 repetitions using 150 mixed samples of plastic and paper. Results showed an overall accuracy of 83.95% with details of 85.3% for plastic and 82.6% for paper/cardboard. Actual capacity reached 13 sorts/minute for plastic and 21 sorts/minute for paper. Implementation of the device increased accuracy from 65% to 84% (19% improvement). The automation system with YOLO algorithm proved effective in improving sorting effectiveness and contributing to waste residue reduction at the 3R TPS.

Abstract

Dalam beberapa waktu, isu terkait environment sustainability menjadi pembicaraan hangat. Hal tersebut terjadi karena akibat dari fenomena climate change yang harus ditangani. Solusi terbaik adalah dengan mengimplementasikan konsep environment sustainability di segala aspek. Kesadaran lingkungan bagi setiap individu harus ditingkatkan. Perguruan Tinggi merupakan institusi pendidikan tertinggi memiliki peran besar dalam melakukan pengelolaan lingkungan dikarenakan banyak sampah/limbah yang dihasilkan dari aktivitas di dalamnya. Telah banyak dilakukan penelitian terkait bagaimana cara meningkatkan kesadaran lingkungan dan implementasi konsep environment sustainability. Penelitian ini bertujuan untuk merumuskan usulan strategi sustainable lifestyle di Universitas ABC Surabaya. Universitas ABC Surabaya telah mencanangkan program Eco Campus. Pada penelitian ini telah dilakukan identifikasi seberapa tingkat Eco Campus, tingkat kesadaran lingkungan, dan beberapa topik kegiatan yang perlu diimplementasikan untuk menunjang Eco Campus yang berkelanjutan. Responden telah dikatakan cukup dengan hitungan sampel Solvin tingkat kepercayaan 95% yaitu 194. Responden banyak tahu mengenai program Eco Campus dan cukup optimis dalam keberhasilan penerapan program Eco Campus. Dinilai responden program Eco Campus yang dijalankan mendapat skala 3 dari 5. Dikatakan Eco Campus jika lingkungan kampus hijau, nyaman dan rindang. Faktor penghambat terbesar dari program Eco Campus adalah kurangnya kesadaran lingkungan. Salah satu strategi yang dapat diusulkan yaitu mengembangkan teknologi ramah lingkungan di kampus ABC Surabaya. Stakeholder yang bertanggung jawab penuh terhadap sustainable lifestyle antara lain mahasiswa, karyawan, manajemen, dan dosen.

Abstract

Salah satu permasalahan yang timbul pada kota-kota besar di Indonesia adalah pencemaran lingkungan akibat sampah. Kota Surabaya merupakan salah satu kota terbesar kedua di Indonesia setelah DKI Jakarta yang juga turut andil dalam peningkatan pencemaran lingkungan akibat sampah. Rata-rata masyarakat mampu menghasilkan kurang lebih 3.014 kg atau setara dengan 3 ton sampah sampah plastik di setiap bulannya menurut data dari Bank Sampah Induk Surabaya. Alur proses daur ulang sampah PET termasuk dalam konsep reverse logistik. Proses pengolahan daur ulang sampah yang terintegrasi dengan baik tentunya akan memberikan manfaat secara optimal bagi pihak-pihak yang yang terkait di dalamnya. Baik dari aspek ekonomi, lingkungan, dan lain sebagainya. Pengembangan model dalam mengalokasian proses daur ulang sampah PET pada struktur reverse logistik di lingkup kota surabaya merupakan tujuan dari penelitian ini. Penelitian ini dilakukan di Bank Sampah Induk, Bank Sampah Unit, Pengepul, DLH dan industri remanufaktur. Pengembangan model dilakukan dengan menggunakan metode Capacited Maximum Covering Problem (CMCP) dengan algoritma matematika Linear Programming (LP). Adapun hasil akhir dalam penelitian ini diharapkan mampu memberikan model pengembangan dalam mengalokasiakan sampah PET secara optimal di lingkup kota Surabaya. Kata kunci: Reverse Logistik, Polyethyelene Terephtalate, CMCP, LP

Abstract

The development of internet brings great influence in business management, especially in supply chain. Transaction conducted through the internet in supply chain known e-fulfillment, is an integrated process from receiving customer order, managing transaction, warehousing, managing transportation, communicating, with customer using media of information technology. Online sales concept opens up the researchers to conduct research on online sales and offline sales simultaneously, known Dual Channel Supply Chain (DCSC). One category of products that are sold using this structure is fashion product. However, selling fashion product using DCSC structure it still has shortcomings and challenges. Due to customer can not make a selection, viewing and researching product and quality inspaction product dierctly. Based on this, some enterprises provide product warranty sales system offered. Warranty as a guarantee given to customer to provide security and comfort for making purchases. Warranty gives impact on price of product, both online and offline. This leads to the need to do a calculation the optimum price considering money back warranty. Optimum price obtained in the model demand function using quadratic programming adressing the objective function in the form profit maximum in individual channel (Pw, Ps dan Po) as well as whole profit in DCSC by considering the value of money back warranty (g). The result obatained is optimum price for two scenarios. There are optimum price in individual channel without money back warranty and optimum price in online channel with accomodate money back warranty. Keywords—dual channel supply chain (DCSC); money back warranty; optimization.

Abstract

Residential high-rises are unique properties that differ from landed properties such as bungalows or terrace houses. They are unique insofar as, after the properties have been occupied, facilities must be jointly managed by residents. The continuous growth of high-rise residential buildings specifies that there is a need for effective ownership and property management system to instill a valuable living experience among high-rise residents in this country. Looking at this scenario, this research takes an initiative to develop a mobile application that supports streamline information with assistive features to improve communication and information sharing for high-rise residential management in Malaysia. This aim is achieved by answering three research objectives, including identifying user requirements, designing the application prototype and developing the artefact and evaluating the artefact. The study was conducted together with LT Sdn Bhd, the property management company responsible in managing and maintaining property related matters of Seroja Apartment. An adopted conceptual framework for property management based on the sustainable indicator dimensions for property management and applicable features from existing mobile application to develop the artefact has been proposed. The conceptual framework was proposed based on literature review and nature of work observed on site. Lastly, the study successfully validated the proposed adopted framework against the artefact, the MyLT mobile application.
