Abstract

Pertumbuhan kota Malang telah berdampak pada peningkatan lahan terbangun dan pengurangan lahan nonterbangun. Dinamika lahan terbangun dan nonterbangun tersebut mempengaruhi interaksi manusia dengan lingkungan dan keadaan ekonomi dan sosial masyarakat kota Malang. Oleh karena itu, informasi distribusi dan luasan lahan terbangun dan nonterbangun diperlukan untuk dapat membantu pengambilan berbagai keputusan perencanaan kota dan wilayah. Sayangnya, belum banyak penelitian terkait distribusi lahan terbangun dan nonterbangun di kota Malang. Penelitian ini bertujuan untuk memetakan distribusi lahan terbangun dan nonterbangun dengan Landsat 8 OLI dan Google Earth Engine (GEE) di kota Malang. Indeks spektral yang dihasilkan dari Landsat 8 OLI seperti NDVI, EVI, BU (NDBI-NDVI), LSWI, dan MNDWI serta titik ketinggian (elevation) dan tingkat kelerengan (slope) yang diturunkan dari ALOS DSM 30m digunakan sebagai masukan untuk klasifikasi tersupervisi. Ragam teknik klasifikasi tersupervisi seperti Support Vector Machine (SVM), Random Forest (RF), Minimum Distance (MD), Gradient Tree Boost (GTB), dan Classification And Regression Tree (CART) digunakan untuk memetakan distribusi lahan terbangun dan nonterbangun. Random Forest menunjukkan akurasi tertinggi dalam memetakan lahan terbangun dan nonterbangun di kota Malang dengan Overall Accuracy 0,96 dan Kappa Coefficient 0,91. Luas area terbangun diestimasi sebesar ~55%-61% dan nonterbangun sebesar ~39%-45% dari total luas kota Malang.

Abstract

One of the problems experienced by MSMEs is conventional recording. Conventional recording problem causes a discrepancy in the recording of production and transactions of goods. This situation can make it difficult for MSMEs to compete with their competitors. The MSME information system can encourage an increase in the competitiveness of an MSME compared to its competitors. This study aims to develop a mobile application for MSME information systems in the city of Malang. The MSME information system was developed using the SDLC waterfall, the Android operating system, and the Firebase data storage service. This research was conducted in 4 stages, namely needs analysis, design, implementation and testing. The needs analysis carried out resulted in 17 functional requirements and 3 non-functional requirements. The design stage produces activity diagrams, sequence diagrams, class diagrams, pseudocode, data design, and interface design. In the implementation phase, the database, program code and interface are implemented. In the testing phase, 4 tests were carried out, namely validation with black box, usability with SUS, portability (Android version 9.0, 10.0,11.0 and internet connectivity), and localization (translation). Blackbox testing shows 100% valid results for functional requirements. Usability testing with the SUS method produces an average score of 89.5 (best imaginable). Compatibility testing and localization testing show valid results. The results of this study can make it easier for MSME actors to record production and transactions of goods and reduce the risk of recording mismatches.
