Abstract

Bioplastic is a plastic that is easily decomposed naturally by the activity of microorganisms without leaving toxic residues because of its that can return to nature. Aim: This study aim to examine the quality of bioplastics from variations of tapioca starch and rice waste raw materials for optimal composition. Methodology and Results: The method used is by mixing the raw material of tapioca starch waste and rice waste with variations in the composition of the material; 100% rice waste, 100% tapioca starch waste, 30% tapioca starch waste: 70% rice waste, 50% tapioca starch waste: 50% rice waste, 70% tapioca starch waste: 30% rice waste. Add 10 mL of glycerol, 30 mL of distilled water, 40 mL of acetate solvent, and 40 ml of 96% ethanol. The product will be tested on a laboratory scale for tensile strength, elongation at break, FTIR tests, and biodegradation according to SNI 7188.7:2016 for the bioplastic category that is easily biodegradable. The result shows that the optimal composition was found in the composition of 100% rice waste raw material with the quality of the tensile strength test results of 3,45 MPa, the value of elongation at break 3,8%, and the value of biodegradation 100%. The resulting bioplastics contain functional groups O-H (hydroxyl) bonded to hydrogen, C-H (alkanes), C≡C (alkynes), esters, simple aromatic compounds, C-O (carboxyl), C=C (alkenes), and hydrocarbons -(CH2)n. Conclusion, significance, and impact of study:  The use of starch to produce biodegradable materials is because it is environmentally friendly, easily degraded, available in large quantities, and affordable, moreover, the bioplastics derived from these waste sources are typically biodegradable, meaning they can break down into natural compounds under certain conditions, reducing environmental pollution.

Abstract

The increasing volume of plastic waste requires innovative solutions that integrate technology with sustainable economic incentives. This study presents the development and evaluation of the ECO-PAY system, an automated plastic bottle waste management system that combines YOLOv8n-based object detection with Radio Frequency Identification (RFID) user identification to support circular economy implementation. The system was designed to identify recyclable plastic bottles in real time, authenticate users, and allocate reward points automatically for each valid disposal transaction. Experimental results show that the YOLOv8n model achieved a maximum confidence score of 93.78% with an average detection accuracy of 72.18% in detecting plastic bottles. System performance testing demonstrated stable real-time operation with a frame rate ranging from 6.58 to 14.91 FPS, enabling fast and continuous transactions suitable for public use. In addition, all transaction data, including user identity, object type, and accumulated points, were successfully recorded in a community-based Excel database in a structured and transparent manner. These findings indicate that the ECO-PAY system is technically feasible, reliable, and effective as a smart waste management solution, contributing to sustainable environmental practices and the practical realization of a circular economy model.

Abstract

Product quality is a key factor in improving the competitiveness of manufacturing companies. PT. X, a spunbond fabric manufacturer, continues to face product defects that affect production quality. This study aims to identify Critical to Quality (CTQ) characteristics, determine the dominant defect types, measure process capability using the Six Sigma method, and propose quality improvement recommendations. The study used all production and defect data as the population, with six months of production data (May–October 2025) selected through purposive sampling based on data availability and completeness. Data were analyzed using the Six Sigma approach, including CTQ analysis, Pareto diagrams, P-Charts, Defects Per Million Opportunities (DPMO), sigma level calculations, and fishbone diagrams. The results indicate that Black Cont (D1), Fil Drop (D7), and Cont Net (D3) are the dominant defects, contributing approximately 92% of total defects. The DPMO values ranged from 12,755,102 to 17,699,115, with sigma levels between 3.87 and 3.99, indicating that the production process performs reasonably well but still requires quality improvement. The novelty of this study lies in the integrated application of Six Sigma to prioritize quality improvement in spunbond fabric production. The findings provide practical recommendations, including improving operator competence, machine maintenance, SOP implementation, raw material quality control, inspection systems, and production environment management to reduce product defects.

Abstract

Usaha mikro, kecil, dan menengah (UMKM) Nasya Cake and Cookies di Kota Surabaya menghadapi kendala keterbatasan kapasitas produksi akibat penggunaan satu unit oven berukuran kecil, sehingga menghambat pemenuhan permintaan konsumen yang terus meningkat. Kegiatan pengabdian ini bertujuan merancang dan menerapkan teknologi tepat guna berupa oven kue berpemanas sirip (finned heating) berbahan bakar gas bernama Oven FINICK (Finned & Quick) untuk meningkatkan produktivitas produksi mitra. Metode pelaksanaan meliputi identifikasi masalah, analisis SWOT, penggalian voice of customer melalui kuesioner, penerapan Quality Function Deployment (QFD) dan House of Quality (HOQ), analisis antropometri untuk aspek ergonomi, perancangan dan fabrikasi alat, serta pengujian kinerja menggunakan metode Objective Matrix (OMAX). Hasil kegiatan menunjukkan bahwa Oven FINICK mampu menampung kapasitas hingga 20 kg per proses pemanggangan, dengan suhu stabil pada kisaran 90°C, waktu pemanggangan rata-rata 25 menit, dan tingkat kecacatan produk hanya 3%. Pengujian bersama mitra menunjukkan peningkatan kepuasan pengguna dari cukup puas menjadi sangat puas dibandingkan oven sebelumnya. Analisis finansial menunjukkan investasi awal sebesar Rp2.690.000 dapat kembali dalam waktu sekitar 23 bulan. Kegiatan ini terbukti mampu meningkatkan efisiensi energi, stabilitas suhu, dan kapasitas produksi UMKM mitra secara signifikan.

Abstract

Risiko gagal bayar pada perusahaan pembiayaan tidak selalu tersebar secara merata karena karakteristik pembayaran konsumen dapat berbeda antarwilayah. Penelitian ini bertujuan memetakan tingkat risiko pembiayaan berdasarkan wilayah pengajuan konsumen serta merumuskan strategi pengendalian yang sesuai dengan profil setiap kelompok. Penelitian menggunakan pendekatan kuantitatif deskriptif dengan studi kasus pada perusahaan pembiayaan di Sidoarjo. Data sekunder mencakup 712 konsumen yang tersebar pada 40 wilayah selama 2025 dan dikelompokkan berdasarkan proporsi pembayaran tepat waktu, keterlambatan 1–90 hari, serta keterlambatan 91–210 hari. Data dibersihkan, ditransformasi menjadi proporsi, kemudian dianalisis menggunakan metode Elbow, algoritma K-Means berbasis jarak Euclidean, dan evaluasi deskriptif antarcluster. Hasil menunjukkan bahwa tiga cluster merupakan struktur yang paling informatif. Cluster 1 terdiri atas 13 wilayah dengan profil WARNING, cluster 2 mencakup 19 wilayah dengan profil EXCELLENT, dan cluster 3 berisi 8 wilayah dengan profil BAD. Centroid cluster berisiko tinggi memperlihatkan proporsi pembayaran tepat waktu 0,6901, keterlambatan 1–90 hari 0,2661, dan keterlambatan 91–210 hari 0,0438. Wilayah Jabon menunjukkan proporsi keterlambatan panjang tertinggi. Penelitian menyimpulkan bahwa clustering wilayah dapat menyediakan dasar objektif untuk diferensiasi kebijakan pembiayaan. Implikasinya, perusahaan perlu menerapkan pemantauan preventif pada wilayah WARNING, ekspansi terukur pada wilayah EXCELLENT, serta pengetatan persetujuan, kunjungan lapangan, dan restrukturisasi pada wilayah BAD.

Abstract

Simulation is applied to the 9969B Printable Splicing Tape product. The ARIMA (Autoregressive Integrated Moving Average) method, which is a method that is based on the values ​​of changes that have occurred in the past, is then used to determine historical data patterns. The aim of this research is to simulate forecasting inventory control needs for Printable Splicing Tape stock. The temporary ARIMA model is p = 8 (PACF dying down plot), d = 2 (one differencing), and q = 1. So, the temporary ARIMA model obtained is (8, 2, 1). The sales forecast for all Printable Splicing Tape products type 9969B on average per month during June-December 2023 is estimated that the average forecast for the company's Inventory Control must stock 608 rolls with a tracking error of -1 (e < 4) so ​​it is very permissible, because it is less than quaternion.
