Abstract

Abstrak Tingkat kematangan pepaya selama ini diidentifikasi secara visual dengan perubahan warna pada kulit buah pepaya. Proses identifikasi ini memiliki beberapa kekurangan di antaranya melelahkan, tidak konsisten, dan memakan waktu. Tujuan penelitian ini adalah membangun sebuah aplikasi pengolahan citra untuk mengidentifikasi tingkat kematangan pada buah pepaya berbasis mobile agar lebih efektif. Metode yang digunakan pada penelitian ini adalah regresi linier berganda. Metode ini digunakan untuk mencari korelasi antara nilai red, green, blue (RGB) dan Brix pada buah pepaya. Pembuatan aplikasi ini menggunakan metode K-Nearest Neighbour (KNN) menggunakan 90 buah papaya dengan tingkat kematangan yang berbeda, yaitu tingkat kematangan mentah, mengkal, dan matang. KNN digunakan sebagai metode untuk kuantifikasi warna sehingga mendekati warna yang sesungguhnya. Hasil pengujian sistem menunjukkan bahwa penerapan aplikasi identifikasi tingkat kematangan buah pepaya memiliki tingkat akurasi sebesar 66,67%. Aplikasi ini butuh untuk dikembangkan lebih lanjut karena masih memiliki tingkat akurasi yang rendah, tetapi aplikasi ini sudah dapat digunakan sebagai alat bantu sortasi pepaya.Kata kunci: pengolahan citra, pepaya, RGB, Brix AbstractThe degree of ripeness of papaya has been evaluated manually based on its skin color parameters. This identification process has several disadvantages, such as exhausting, inconsistent, and taking time. This research is set to build an application of image processing for identifying a papaya maturity level based on the mobile application. The method used in this research is multiple linear regression to find the correlation between red, green, blue (RGB) and Brix values in papaya. The mobile application is developed by using K-Nearest Neighbour (KNN) method for 90 papayas with different levels of maturity; unripe, moderate, and ripe. KNN is used to estimate the color of papaya skin quantitatively.

Abstract

Pandemi COVID-19 berdampak pada mobilitas manusia, khususnya di bidang penerbangan. Penurunan trafik penumpang yang dirasakan pengelola bandara Yogyakarta (Bandara Internasional Yogyakarta - YIA dan Bandara Adisutjipto - JOG) membuat pengelola bandara ingin mengetahui pilihan penumpang untuk bepergian di masa pandemi COVID-19. Pengumpulan data dilakukan melalui survei (daring dan luring) dan observasi lapangan. Data tersebut mencakup demografi responden serta persepsi atau preferensi penumpang untuk bepergian selama pandemi. Hasil penelitian menunjukkan bahwa sebagian besar penumpang masih ragu-ragu (moderat) apakah akan menunda atau melanjutkan perjalanan udara selama pandemi. Hasil uji ANOVA menunjukkan bahwa semua faktor demografi seperti jenis kelamin, tujuan perjalanan, usia, dan pilihan bandara memiliki signifikansi dengan respon. Secara umum, penumpang ingin terbang secepat mungkin dalam satu hingga tiga bulan ke depan. Oleh karena itu, pengelola bandara harus memberikan layanan yang menjamin keselamatan pengguna agar terhindar dari paparan virus. Selain itu, perlu adanya kebijakan yang jelas dari pemerintah terkait mobilitas penumpang dan angkutan umum agar operasional angkutan umum khususnya penerbangan dapat berjalan dengan baik di masa pandemi.

Abstract

Preventive maintenance is a planned and scheduled maintenance method that is carried out before a machine failure occurs. The maintenance schedule can be determined based on experience, historical data, or recommendations. Selecting the maintenance schedule greatly affects the production system. The Clin machine in cement manufacturing has an important role in the cement production process. During treatment, the client machine cannot produce clinker, so it is necessary to plan a production system to meet the demand. This paper aims to design an optimization model for determining the preventive maintenance schedule for cement manufacturing by considering the production process and inventory control. Mathematical models with binary options are used to model that system. The model supports showing the optimal preventive maintenance schedule for the ciln machines with a binary decision each period. This mathematical model describes the interaction of production planning, inventory control, and scheduling of total maintenance on a kiln machine. The goal of this system is to determine the optimal preventive maintenance schedule with minimum costs. In addition, the system's output is the optimal production and inventory decision rule for each period. Based on the analysis and simulation of the model with the deterministic and dynamic demand, the optimal preventive maintenance schedule is in the 9th and 21st periods. The kiln machines are maintained every July with minimal costs. The model scenario shows the interaction of the variables and the sensitivity of the production capacity and demand to the decision rule of the variable.
