Get PDFAbstract—Indonesia is a maritime country located on the equator, causing Indonesia to have a tropical climate. This causes a lot of convective clouds to grow because they get water supply from the sea so that information on the distribution of convective clouds is important for weather analysis purposes. On December 13, 2020, floods submerged several villages in Pace District, Nganjuk Regency due to the overflow of the Kolosoko river due to heavy rains. The purpose of this study was to see the distribution of convective clouds during heavy rains in Pace District. The data used in this study is Himawari-8 satellite data channels 3, 4, 5, 7, 8, 10, 13 and 15 to process the distribution of convective clouds. This research uses descriptive analysis method with daily weather parameters and Himawari-8 satellite imagery. Analysis of satellite image data using Cloud Convective Overlays (CCO) and Red Green Blue (RGB) CS and NC methods. This method is used to view the image of convective clouds making it easier to analyze the distribution of convective clouds. The results obtained in satellite images show significant growth of convective clouds while in weather radar images show moderate rain reflectivity due to radar limitations.

Modifikasi Multimedia Development Lifecycle dan Proses Produksi Video Dalam Pembuatan Perangkat Multimedia Untuk Film Dokumenter: “Krupuk Amplang Balikpapan”
Get PDFAbstract— Proses pembuatan produk multimedia menggunakan pendekatan yang identik dengan rekayasa perangkat lunak (SDLC). Pada pengembangannya, SDLC mengalami modifikasi sesuai dengan ruang lingkup dataset multimedia dan memunculkan metodologi Multimedia Development Lifecylce (MDLC). Namun metodologi ini memiliki kelemahan apabila produk multimedia yang dikembangkan berbasis waktu karena memiliki pendekatan yang berbeda. Sebagai contoh produksi film umumnya mementingkan tahap pra-produksi, produksi dan pasca-produksi seperti pada alur pengerjaan proses produksi video. Tahapan ini belum pernah diakomodasi sebelumnya pada standar MDLC. Kami mengusulkan modifikasi MDLC untuk mengkombinasikan proses produksi video agar dapat membantu pihak pengembang dalam merencanakan dan membangun produk multimedia berbasis waktu. Untuk memvalidasi usulan metode ini, kami menggunakan studi kasus film dokumenter krupuk Amplang Balikpapan. Studi kasus ini dipilih karena krupuk Amplang Balikpapan kurang dikenal oleh masyarakat terutama dari luar Balikpapan. Popularitasnya masih dibawah krupuk Amplang Samarinda. Film dokumenter ini perlu dilengkapi dengan perangkat pelengkap dalam bentuk website interaktif sehingga relevan dengan penerapan modifikasi MDLC. Hasil pengujian menggunakan Film Analysis Guide serta uji t berpasangan terhadap data responden setelah memakai produk ini dapat disimpulkan bahwa metode usulan modifikasi MDLC dapat menjadi alternatif pengembangan produk multimedia berbasis waktu.

Abstrak— The production of multimedia products follows a methodology that is identical to software engineering (SDLC). During the process of its development, the Standard Development Lifecycle (SDLC) was altered to accommodate the comprehensive nature of the multimedia dataset, which resulted in the emergence of the Multimedia Development Lifecycle (MDLC) methodology. On the other hand, if the multimedia product that is being developed is time-based, then this methodology is inadequate because it takes a different approach. For instance, the pre-production, production, and post-production stages of film production are the most important ones to focus on, just as they are in the workflow of the video production process. The MDLC standard has never before made room for this level in any of its iterations. As a result, we suggest a change to the MDLC in order to combine the video production process in order to provide developers with assistance in the process of planning and producing time-based multimedia products. In order to demonstrate the viability of this proposed strategy, we conducted a case study based on the documentary film crackers Amplang Balikpapan. The Amplang Balikpapan crackers were selected for this case study because they are not as well known by the general public, particularly those who are not from the Balikpapan area. Its notoriety is not yet on par with that of the crackers sold in Amplang Samarinda. In addition, in order for this documentary to be useful in the process of implementing the MDLC alteration, it needs to be accompanied with supplementary resources. One example of these tools is an interactive website. The results of the test using the Film Analysis Guide and a t-paired test of the respondent's data after using this product can be obtained by saying that the modified MDLC method can be an alternative time-based multimedia product development. This was determined by comparing the data from both of these test.

Pengaruh Laju Alir pada Proses Spray Drying terhadap Karakteristik Fisiko Kimia Mikrosfer Glibenklamid menggunakan Polimer Kitosan dan Penyambung Silang Natrium Tripolifosfat
Get PDFGlibenklamid memiliki waktu paruh yang singkat, sehingga modifikasi pelepasan terkendali diperlukan dan dapat dicapai dengan mikrosfer. Kitosan sebagai polimer disambung silang dengan natrium tripolifosfat (NTPP), selanjutnya mikrosfer dibuat menggunakan metode spray drying. Laju alir yang rendah menghasilkan suhu outlet yang tinggi pada spray dryer sehingga variasinya dapat menghasilkan karakteristik mikrosfer yang berbeda. Tujuan penelitian ini untuk menganalisis pengaruh laju alir terhadap karakteristik fisiko kimia mikrosfer yang diperoleh. Variasi laju alirnya adalah 7,5 ml/menit untuk F1 dan 6,5 ml/menit untuk F2. Identifikasi gugus fungsi menunjukkan adanya semua puncak glibenklamid dan gugus spesifik yang membuktikan terjadinya sambung silang antara kitosan dengan NTPP. Hasil identifikasi titik lebur dan energi termal menunjukkan kitosan membentuk ikatan sambung silang dengan NTPP serta puncak glibenklamid tidak ditemukan karena glibenklamid terselubungi oleh kitosan-NTPP. Rata-rata ukuran partikel F1 adalah 5,00 µm sedangkan F2 adalah 4,02 µm. Morfologi bentuk permukaan keduanya menghasilkan permukaan partikel yang sferis tetapi pada F2 memiliki permukaan yang lebih halus. Efisiensi enkapsulasi dan perolehan kembali F2 lebih tinggi dari F1, sebaliknya indeks pengembangan dan kandungan lembab F1 lebih tinggi. Profil disolusi kedua sampel menunjukkan pelepasan yang bertahap dibandingkan dengan glibenklamid murni. Perbedaan laju alir menyebabkan perbedaan bermakna karakteristik fisikokimia mikrosfer sehingga menghasilkan perbedaan pelepasan glibenklamid
