Judul: Interactive Dashboard for Land Change
using Shiny Framework.
Abstrak: Perubahan lahan atau tutupan lahan adalah perubahan atribut fisik, seperti vegetasi, badan air, dan struktur buatan manusia, selama periode tertentu dalam wilayah geografis tertentu. Perubahan lahan dapat terjadi secara alami maupun karena perbuatan manusia dengan tujuan untuk pemukiman, kegiatan pertanian, pengembangan hutan, dan pengembangan badan air. Saat ini data lahan dapat diperoleh melalui teknologi penginderaan jauh seperti sistem informasi geografis (SIG) dan citra satelit, namun belum terdapat perangkat interaktif yang menunjukkan perubahan lahan dari waktu ke waktu. Tujuan dari penelitian ini adalah membuat dashboard interaktif untuk memvisualisasi dan menganalisis data perubahan lahan tahunan atau periode tertentu sesuai informasi yang dibutuhkan pengguna. Pembuatan dashboard dilakukan menggunakan package Shiny yang tersedia pada bahasa pemrograman R. Hasil penelitian berupa dashboard interaktif dengan fitur memilih jenis grafik yang akan ditampilkan, memilih tipe/jenis lahan, dan memilih rentang waktu tahunan. Pengujian dengan black box user acceptance testing menunjukkan bahwa sistem yang dikembangkan telah berhasil memenuhi kebutuhan yang diharapkan., Land use cover or land cover change is a change in physical attributes, such as vegetation, water bodies, and man-made structures, during a certain period within a certain geographic area. Land change can occur naturally or due to human activities for settlement, agricultural activities, forest development, and water body development. Currently, land data can be obtained through remote sensing technology such as geographic information systems (GIS) and satellite imagery, but there is no interactive tool that shows land change over time. The purpose of this research is to create an interactive dashboard to visualize and analyze annual or specific period land change data according to user needs. The dashboard is created using the Shiny package available in the R programming language. The research results in an interactive dashboard with features to select the type of graph to be displayed, select the type of land, and select the annual time range. Testing with black box user acceptance testing shows that the developed system has successfully met the expected needs

Judul: Dashboard Interaktif Monitoring Data Tinggi Muka Air Tanah Menggunakan Framework Shiny
Abstrak: Lahan gambut merupakan lahan yang sangat sensitif terhadap kebakaran dikarenakan tinggi air muka yang rendah saat musim kemarau. Kebakaran hutan dan lahan (Karhutla) di Indonesia tercatat sebagai salah satu bencana yang paling banyak terjadi. Badan Nasional Penanggulangan Bencana (BNPB) Indonesia mencatat 579 kasus bencana karhutla pada tahun 2021 dan 252 kasus karhutla pada tahun 2022. Salah satu upaya yang bisa dilakukan sebagai pencegahan kebakaran lahan yaitu dengan memantau keseimbangan tinggi muka air tanah. Pengembangan dashboard interaktif monitoring TMA digunakan sebagai media dalam mengakses informasi pemantauan tinggi muka air tanah dan bisa digunakan sebagai acuan dalam memprediksi status kewaspadaan kebakaran hutan dan lahan di masa mendatang. Penelitian ini menghasilkan beberapa fitur yang dapat digunakan oleh pengguna seperti select location, select monitoring date, select rounding date, monitoring plot, dan download data yang dikembangkan menggunakan package Highcharter dan package Shiny dashboard pada bahasa pemrograman R. Pengujian yang dilakukan pada penelitian ini menggunakan metode blackbox testing yang menghasilkan keputusan bahwa sistem yang kembangkan sudah memenuhi kebutuhan yang diharapkan., Peatland is land that is very sensitive to fire due to the low water table during the dry season. Forest and land fires in Indonesia are recorded as one of the most frequent disasters. The Indonesian National Disaster Management Authority (NDMA) noted that there were 579 cases of forest and land fires in 2021 and 252 cases of forest fires in 2022. One effort that can be taken to prevent land fires is to monitor the balance of the groundwater level. The development of an interactive monitoring dashboard for TMA is used as a medium to access information on monitoring groundwater levels and can be used to be a reference in predicting the alert status of forest and land fires in the future. This research produces several features that can be used by users such as select location, select monitoring date, select rounding date, monitoring plots and download data which were developed using the Highcharter package and the Shiny dashboard package by R programming language. The tests carried out in this study used the black box testing method. which results in the decision that the system being developed meets the expected needs.

Judul: Mitochondrial DNA Gene Organization and Phylogenetic Relationship of Naja siamensis
Abstrak: Naja siamensis is one of Asiatic cobra in the Family of Elapidae, known as a cryptic snake. It has many morphological variations that lead to misidentification. Misidentification can cause the wrong concept in developing antivenom types due to high snakebite cases occur in Thailand. Thus, an accurate species identification using a molecular approach is crucially required. Mitochondrial DNA has been used widely in snake molecular studies. These studies were aimed to determine the arrangement of the N. siamensis partial mitochondrial genes using reptile-oriented primers and to reveal the phylogenetic relationship among other species of Asian cobra. DNA extraction was carried out based on the standard DNA salting-out protocol and was conducted by bioinformatics analysis using BLASTn and MEGA 6 software. Gene annotation was performed against N. kaouthia complete genome. A total of 3121 bp of N. siamensis mtDNA genes were sequenced consisting of partial of six regions: 16S rRNA, ND1, tRNA-Ile, CRII region, tRNA-Leu, tRNA-Gln, and COI genes. The mtDNA gene organization of N. siamensis was predicted to has a similar pattern with the common Elapidae mtDNA gene organization. This study showed that there is a monophyletic form in Naja genus and N. kaouthia is the closest species with N. siamensis based on partial 16S rRNA and ND1 gene.
