Abstract

Tempe merupakan makanan tradisional masyarakat Indonesia yang sarat protein, vitamin dan jugamineral. Masyarakat Jawa Timur merupakan konsumen tempe terbesar di Indonesia. Dengan potensipasar yang sedemikian besar, maka Usaha Kecil Tempe di Jawa Timur harus dapat memperbaiki prosesterus menerus agar dapat memenuhi kebutuhan pasar baik secara kuantitas maupun kualitas. Studi inibertujuan untuk memberikan rekomendasi kepada sebuah Usaha Kecil Tempe di Kediri untuk dapatmeningkatkan kuantitas produksi dengan cara menghilangkan atau mereduksi kegiatan yang tidak bernilaitambah. Saat ini, proses produksi tempe masih dilakukan secara manual tanpa memperhatikan aliranproses. Untuk itu, diusulkan perbaikan dengan menggunakan prinsip Kaizen yang bertujuan untukmelakukan perbaikan secara bertahap dan berkelanjutan. Usulan perbaikan adalah berupa perubahan tataletak proses produksi dan aplikasi prinsip karakuri pada proses produksinya. Dengan implementasirekomendasi maka diprediksi dapat meningkatkan kapasitas produksi tempe, dimana waktu produksimenjadi lebih singkat kurang lebih 20%.

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

Chicken slaughter process waste is divided into two types, solid waste and liquid waste. Almost all of the waste generated by the chicken slaughter process can be reused. Lately, Vocational High School in Pasuruan, East Java, has Livestock Agribusiness unit that made a waste treatment program to deal with the problem of waste from the surrounding chicken slaughter process. However, some chicken slaughter process waste cannot be reprocessed and is directly dumped into the sewer due to limited technology. The type of waste that cannot reprocess is blood and chicken feather waste. This research aims to process the waste into high-quality fish food by applying the principle of automation and integrating machines with existing chicken cutting machines. The application of this appropriate technology begins with observing the existing conditions and the process of designing, manufacturing, and testing equipment carried out at Vocational High School in Pasuruan. The research resulted in designing and manufacturing machines that support waste treatment of blood and chicken feathers from Livestock Agribusiness. The machine design consists of three main components: a blood and chicken feather grinder, a vertical mixer, and a fish feed press machine. The expectations of this machine design will support productivity and concern for waste management, which can also build environmentally friendly standards in the Livestock Agribusiness unit of Vocational School in Pasuruan.

Abstract

Limbah proses pemotongan ayam secara umum terdiri dari limbah padat dan cair. Hampir semua limbah dari proses pemotongan ayam dapat dimanfaatkan kembali. SMKN 1 Grati adalah sekolah vokasi di Pasuruan, yang memiliki unit Agribisnis Peternakan. Namun, masih belum adanya penanganan khusus terhadap beberapa limbah dari proses pemotongan ayam, dimana saat ini limbah hanya dibuang begitu saja ke saluran pembuangan. Penelitian ini bertujuan untuk membantu menyediakan mesin pengolah darah dan bulu ayam menjadi tepung darah atau bulu, yang dapat diolah menjadi bahan pakan atau pupuk, dengan menerapkan prinsip semi otomatisasi. Dimana terdapat mesin kukus inovatif dan oven konveyor. Penerapan teknologi tepat guna ini diawali dengan mengamati kondisi eksisting, perancangan solusi, lalu pembuatan dan pengujian alat. Desain mesin terdiri dari mesin kukus inovatif yang dapat menjalankan fungsi kukus sekaligus pencacah darah atau bulu ayam, serta terdapat oven konveyor listrik untuk membantu proses pengeringan hasil pengukusan darah atau bulu ayam. Harapan dari implementasi rancangan mesin ini, dapat mendukung produktivitas dan mengurangi dampak buruk pada lingkungan, dengan meningkatkan kepedulian terhadap pengelolaan limbah melalui kegiatan recycle. Kedepannya, sistem pengelolaan limbah di Rumah Potong Ayam diharapkan terus dilakukan perbaikan hingga dapat ditetapkan standar ramah lingkungan.

Abstract

Keilmuan Teknik Sistem dan Industri selama ini lebih banyak dikaitkan dengansektor manufaktur. Namun sebenarnya disiplin ini juga sangat relevan untuk diterapkandi sektor layanan publik oleh instansi pemerintahan. Penerapan konsep LeanSix Sigma (LSS) terbukti mampu menjawab tantangan efisiensi, efektivitas, danpeningkatan kualitas layanan. Metode ini tidak hanya berfokus pada pengurangandefect atau kesalahan dalam proses layanan, tetapi juga mengutamakan pencarianprosedur terbaik untuk pemantauan dan perbaikan berkelanjutan. Maka dariitu, program pengabdian masyarakat ini dirancang untuk mendampingi OrganisasiPerangkat Daerah (OPD) penyelenggara layanan perizinan dan non-perizinan dilingkungan Pemerintah Kota (Pemkot) Surabaya dalam mengimplementasikan konsepLSS. Prinsipnya adalah pengelolaan data dari total waktu penyelesaian terhadaptarget yang telah ditetapkan untuk dapat mengukur performansi layanan dari setiapOPD melalui parameter process capability dan sigma level. Hasil dari pendampinganini menunjukkan bahwa meskipun para OPD telah memenuhi target waktu layanan,namun sebaran waktu layanan yang tercatat masih terlalu tinggi sehingga akhirnyaberdampak pada tingkat kepuasan masyarakat yang bervariatif. Hasil pengolahandata selanjutnya dianalisis berdasarkan 10 waste untuk menemukan penyebab waktulayanan belum konsisten. Hasil analisis ditindaklanjuti dengan perubahan prosedurkerja dan proses bisnis sebagai bentuk continuous improvement.

Abstract

This study investigates the determinants of consumers’ purchase decisions for remanufactured laptops in Indonesia, where a limited understanding of remanufacturing continues to hinder adoption of the circular economy. Rather than examining purchase intention, the study model’s purchase decision as a trade-off-based decision process reflects consumers’ decision-making of remanufactured products. A MaxDiff (Best–Worst Scaling Case 1) discrete choice experiment was conducted involving 434 Indonesian undergraduate students. Preferences were modeled within a random utility theory framework using multinomial logit estimation via maximum likelihood, and consumer heterogeneity was subsequently examined through latent class analysis, revealing four distinct preference segments. The results show that the dominant driver of purchase decision is functionality expectation, followed by perceived consumer effectiveness and perceived safety, indicating that consumers prioritize performance assurance and risk reduction over environmental motivations. Environmental consciousness and social influence have weaker effects, indicating an attitude–behavior gap for sustainable consumption. Furthermore, the latent class analysis identified four heterogeneous consumer segments with varying valuation logics. This suggests practical implications for future strategies to increase the purchase decision of remanufactured electronics in emerging economies through knowledge creation about the customer perceptions, where a greater emphasis on functional reliability, certification, and transparent quality communication may prove more effective than traditional environmental appeals.
