Abstract

Singkawang City is a coastal and hilly city. Flooding incidents have caused considerable material damage, displacement of people, and loss of lives. Floods in Singkawang occur almost yearly. In general, the floods in Singkawang are caused by natural factors, exceptionally high rainfall. Considering the significant impact of floods on the development of Singkawang City, it is necessary to establish flood vulnerability zoning based on rainfall in the city.An analysis is conducted on parameters that influence flood incidents, including the slope of the land, elevation, soil type, land cover, and hydrological analysis of rainfall data to create a flood vulnerability zoning map in Singkawang City. Then, an overlay is performed on the four parameters that affect floods, resulting in a map showing the distribution of inundation due to the maximum planned flood discharge (Q) generated from the hydrological analysis based on rainfall.The flood vulnerability map analysis results based on 4 data parameters that affect flood events obtained that the flood-safe area in Singkawang City covers an area of 14863.97 ha (27.04%). In contrast, areas not prone to floods cover 24571.74 ha (44.70%). Areas vulnerable to floods cover 11476.22 ha (20.87%), and regions highly vulnerable to floods cover 3567.28 ha (6.49%). Based on the results of hydrological analysis based on rainfall, it is obtained that the area of Singkawang City mostly experiences inundation due to the maximum planned flood discharge occurring at a 2-year interval in the Small Semelagi River Zone (353.5 ha), at a 5-year gap in the Small Semelagi River Zone (327.4 hectares), at a 10-year gap in the Selakau River Zone (401.4 ha), at a 20-year interval in the Selakau River Zone (473.1 ha), at a 50-year interval in the Selakau River Zone (545.9 ha), and at a 100-year gap in the Selakau River Zone (617.7 ha).

Abstract

The system for handling product data in a store is one that can facilitate efficient operation. It is still not utilized by the majority of stores, which continue to manage their product data manually. Application for the Goods Data Management System at the Aru Raya Store, which will be sent to the stage of system implementation used to manage transactions at the Aru Raya Store. Numerous flaws in the current system have been discovered during the course of the field research procedure. Despite the fact that there is nothing as a whole, but rather leads to specific issues, it is anticipated to have a significant impact on system users. Because it will be quicker, more accurate, and more precise with this information system, the author of the information system designed the supply chain for Baceno Bag Convection. The author of this new system realized an effective system at Aru Raya Store in Lubuk Begalung by creating it utilizing the PHP, UML, and MySQL Database programming languages.

Abstract

Program pengabdian ini bertujuan memperkuat ketahanan pangan rumah tangga di wilayah perkotaan melalui model pemberdayaan berbasis budidaya lele dalam galon yang terintegrasi dengan urban farming cabai dan sereh. Kegiatan dilaksanakan di RT 005/RW 002 Kelurahan Sawah Lama, Tangerang Selatan, dengan melibatkan partisipasi aktif 18 warga. Metode pelaksanaan mencakup sosialisasi, pelatihan teknis, praktik lapangan, dan pendampingan menggunakan pendekatan Participatory Action Research (PAR). Evaluasi dilakukan melalui observasi langsung dan wawancara semi-terstruktur untuk mengidentifikasi perubahan pada aspek pengetahuan, keterampilan, dan keterlibatan warga. Hasil kegiatan menunjukkan peningkatan yang signifikan, yaitu kenaikan pengetahuan teknik budidaya dari 30% menjadi 85%, keterampilan praktik dari 25% menjadi 80%, serta partisipasi warga dalam urban farming dari 35% menjadi 75%. Kesadaran pemanfaatan limbah plastik juga meningkat melalui penggunaan galon bekas sebagai media budidaya, dan muncul inisiatif warga untuk mengembangkan pembibitan tanaman secara mandiri. Temuan ini mengindikasikan bahwa integrasi sederhana antara budidaya ikan dan tanaman dapat menjadi strategi efektif untuk mendukung ketahanan pangan keluarga di kawasan urban padat penduduk. Model ini memiliki potensi untuk direplikasi di wilayah lain dengan menyesuaikan kondisi sosial dan ketersediaan sumber daya lokal
