Abstract

Kemajuan teknologi informasi mendorong perusahaan untuk meningkatkan efisiensi operasional melalui sistem manajemen persediaan yang terintegrasi. Penelitian ini bertujuan merancang dan mengimplementasikan sistem informasi pengelolaan persediaan berbasis web pada CV. Digital Warna Mandiri menggunakan framework Yii2 dan bahasa pemrograman PHP. Sistem dilengkapi dengan metode Holt Winter untuk peramalan kebutuhan bahan, serta Economic Order Quantity (EOQ) dan Reorder Point (ROP) untuk menentukan jumlah dan waktu pemesanan optimal. Hasil implementasi menunjukkan sistem mampu mengelola data stok, transaksi masuk dan keluar, serta menghasilkan nilai peramalan dengan tingkat akurasi Mean Absolute Percentage Error (MAPE) di bawah 10%. Integrasi EOQ dan ROP secara otomatis membantu perusahaan menekan risiko kelebihan stok dan kekurangan stok. Secara akademik, penelitian ini berkontribusi pada penerapan metode kuantitatif dalam sistem informasi stok berbasis web, sedangkan secara praktis, sistem ini dapat dijadikan model implementatif bagi UMKM dalam meningkatkan efisiensi perencanaan bahan baku dan pengambilan keputusan operasional.

Abstract

The Free Nutritious Meal Program in Surabaya is a major government initiative designed to improve child nutrition and reduce hunger among schoolchildren from low-income families. Despite its importance, the program faces significant challenges of food loss and waste due to inefficiencies in transportation, storage, and demand matching. This study introduces a Smart MBG Cloud Platform and applies a linear programming model to optimize the program’s supply chain under two operational scenarios: a baseline system without Information Technology (IT) support and an IT-enhanced system integrating route optimization and digital inventory monitoring. Simulation results reveal substantial efficiency gains in the IT-integrated model. This study was conducted using a mixed-method approach involving samples from schools as beneficiaries and the Nutrition Fulfillment Service Unit as providers of free nutritious meals. Using simulation data from five kitchens and ten schools and conducting 50 stochastic replications, the IT-enhanced model achieved a 28% reduction in transportation cost and the total objective value declined by 22%, compared to without IT support scenario. These results demonstrate that incorporating digital route planning and inventory monitoring not only reduces operational expenses but also mitigates organic waste, ensuring fresher meal delivery and supporting sustainability targets. These improvements highlight the potential of digital tools to minimize inefficiencies, ensure fresher meal delivery, and strengthen the nutritional impact of the program. Beyond operational savings, the IT-based model contributes to reduced organic waste generation and aligns with broader sustainability goals. The findings provide empirical evidence that digital transformation can significantly enhance the performance of public food programs and offer practical insights for policymakers to replicate these strategies in similar urban initiatives.

Abstract

Bencana banjir memiliki dampak sistemik yang signifikan pada berbagai aspek kehidupan masyarakat. Oleh karena itu, perlu dilakukan upaya-upaya preventif dan mitigasi bencana sebelum terjadinya banjir, serta aksi cepat dan tanggap bencana pascabanjir untuk meminimalkan dampak dan memperbaiki kerugian yang timbul. Surabaya sebagai kota terbesar kedua di Indonesia juga sering mendapatkan dampak banjir sebagai salah satu bencana yang sering terjadi. Penelitian ini mencoba mengkaji Early Warning System untuk bencana banjir khususnya di rumah pompa pada daerah Kenjeran. Pengukuran sistem dibantu dengan sensor jarak ultrasonic dan infrared untuk mendapatkan ketinggian air serta kajian dengan data pada Weather API. Intensitas curah hujan pada 3 tahun ini mengalami peningkatan, meskipun dalam rerata yang masih dapat ditolerir sehingga masih dapat dialihkan dan direkayasa sehingga banjir dapat diminimalisir. Jumlah EWS yang ada di Surabaya, khususnya di daerah Kenjeran sudah sesuai karena telah mencakup 80% dari areal wilayah tersebut dan mampu mereduksi dampak banjir dengan mempercepat penyurutan air. Namun dari data yang dikumpulkan ketinggian air laut meningkat cukup signifikan, khususnya pada saat tertentu dimana air laut pasang dan perubahan iklim serta adanya siklon tropis sehingga banjir rob masih menjadi ancaman dan permasalahan untuk diselesaikan

Indonesian SMEs go International! By making sustainability reporting in SMEs, it is hoped that it can improve the reputation of SMEs and support SMEs to go international. This community service activity was carried out with SME partner Bakery Glory in Surabaya in collaboration with the Melati Nusantara activity series. With the aim of accelerating the understanding of sustainable production to develop the potential of SMEs so that their products can be accepted in the international market.
