Abstract

As the capital city of West Sumatra, Padang only has a few tourist destinations. Domestic tourists choose to go to other cities, such as Bukittinggi, Payakumbuh, and Solok, while international tourists go to Mentawai Island. Marawa Beach Club Padang (MBC), hopefully, could be one of the tourist attractions that is available in Padang. This beach club offers both natural and human-made spots. This research was designed to investigate what are the tourist's motivation to go to a beach club. Further, since the majority of Padang citizen are Muslim, this research will explore their understanding of halal tourism that has been implemented in MBC. This research was conducted as a qualitative approach research which deep observation and structured interviews were done with 25 informants. The informants were the tourists we found in the club whom we classified the middle-class tourists since the beach club offers quite high standards of price. The results show that tourists got motivated to go because of the view the club offers, and the vibes to chill, relax, and enjoy food while the understanding of halal tourism is still very low.

Abstract

Penjualan pupuk NPK, khususnya grade 13 8 27 4 + 0,5B, terus meningkat seiring dengan meningkatnya kesadaran petani akan pentingnya pemupukan yang efektif dan efisien. PT. XYZ, sebagai salah satu anak perusahaan AB Group Indonesia yang bergerak di bidang industri pupuk, menghadapi tantangan dalam memenuhi permintaan akibat ketidaksesuaian antara stok yang tersedia dengan permintaan. Selain itu, ketidaktepatan pengelolaan bahan baku dan kurangnya ketersediaan karung turut memperburuk situasi stok di gudang. Penelitian ini bertujuan untuk meramalkan permintaan pupuk NPK grade 13 8 27 4 + 0,5B guna mengoptimalkan pengelolaan stok. Metode yang digunakan meliputi Single Moving Average (SMA) dan Single Exponential Smoothing (SES), dengan pengukuran kesalahan melalui Mean Absolute Deviation (MAD), Mean Square Error (MSE), dan Mean Absolute Percentage Error (MAPE). Hasil penelitian menunjukkan bahwa metode SES dengan α = 0,6 menghasilkan tingkat kesalahan terkecil, menjadikannya metode yang paling tepat untuk diaplikasikan di PT. XYZ. Penelitian ini diharapkan dapat mendukung perencanaan strategis perusahaan dalam mengelola persediaan dan memastikan kelancaran distribusi pupuk.

Abstract

PT X is a pharmaceutical manufacturing company producing cosmetics, household health supplies, medicines, and quasi-drugs. During the internship period of 8 months, various aspects of agro-industrial logistics were observed, including demand planning. The study focused on addressing recurring issues of stockouts of talcum powder, specifically Salisil Talk Wangi 45 grams, caused by inaccurate forecasting and manual estimation methods. To resolve this, the Double Moving Average method was applied to forecast demand for the product. The results showed that for the Blue variant of Salisil Talk Wangi 45 gr, the forecasting error was MAD = 1.236 and MAPE = 7%. For the Yellow variant, MAD = 1.109 and MAPE = 7%, and for the Green variant, MAD = 1.109 and MAPE = 8%. These results suggest that the Double Moving Average method is effective in supporting raw material planning for better production continuity.

Abstract

Penelitian ini bertujuan merancang Sistem Informasi Manajemen Aset berbasis web di Universitas Mercubaktijaya melalui pendekatan rekayasa perangkat lunak yang sistematis menggunakan model Waterfall. Penelitian ini menitikberatkan pada permasalahan yang terjadi dalam proses pengelolaan aset yang masih bersifat semi-manual dan berbasis spreadsheet, yang menyebabkan duplikasi data, kesalahan dalam proses input data, lemahnya pelacakan riwayat aset, serta ketidakefisienan dalam pelaporan. Pada Unit Aset dan Transportasi serta BAUK, pengumpulan data dilakukan melalui observasi, wawancara, dan analisis dokumen. Proses perancangan sistem menghasilkan perumusan 12 kebutuhan fungsional dan 7 kebutuhan non-fungsional yang mencakup pengelolaan peralatan kantor, peralatan laboratorium, dan kendaraan operasional. Pengembangan pemodelan sistem dilakukan dengan menggunakan seperangkat diagram UML yang lengkap, yang terdiri dari 1 diagram use case, 3 diagram activity, 4 diagram sequence, dan 1 diagram class. Selain itu, mockup awal UI/UX dirancang untuk merepresentasikan antarmuka sistem berdasarkan prinsip konsistensi, keterbacaan, dan kemudahan navigasi. Kontribusi utama dari penelitian ini adalah penyajian blueprint sistem yang terperinci dan sistematis berdasarkan kebutuhan pengelolaan aset di lingkungan perguruan tinggi, yang dilengkapi dengan dokumentasi UML lengkap dan dapat dijadikan acuan pada tahap implementasi sistem di masa mendatang.
