Judul: Front-End Module at Post Forest and  Land Fire Area Severity Level Assesment System
Abstrak: Kebakaran hutan dan lahan (karhutla) merupakan salah satu fenomena berdampak besar yang sering terjadi di Indonesia, terutama pada musim kemarau. Dalam perumusan program rehabilitasi terhadap area yang terkena dampak karhutla, salah satu informasi yang dibutuhkan adalah tingkat keparahannya. Saat ini, metode penilaian fire severity belum terintegrasi dengan sistem maupun basis data, sehingga informasi hasil penilaiannya belum dapat diakses oleh pihak yang membutuhkannya. Oleh karena itu, penelitian ini bertujuan membangun Sistem Penilaian Tingkat Keparahan Area Pasca Kebakaran Hutan dan Lahan, khususnya pada modul front-end. Pembangunan modul front-end dilakukan dengan mengadopsi metode prototyping yang meliputi tahapan komunikasi dengan stakeholder, perencanaan dan pemodelan cepat sistem, konstruksi prototipe, pengujian dan feedback sistem. Fitur utama yang disediakan modul front-end meliputi registrasi akun, login, melihat peta sebaran lokasi area pasca karhutla, menambahkan penilaian karhutla baru, melihat detail data laporan, mengubah data laporan, menghapus data laporan, dan melihat data pengguna. Hasil black- box testing menunjukkan semua fitur utama telah berjalan sesuai dengan ekspektasi. Kelebihan dari modul front-end ini di antaranya fitur pencarian koordinat otomatis, kemampuan membagi penilaian sebuah area karhutla menjadi beberapa plot, fitur untuk memperbaiki kesalahan entri data laporan setelah dibuat, serta performa yang baik. Beberapa rencana perbaikan sistem selanjutnya meliputi penambahan jenis dan modul manajemen pengguna, penambahan fitur filter dan search, serta penambahan mekanisme verifikasi registrasi akun., Forest and land fire (karhutla) is an impactful phenomenon frequently occurring in Indonesia, especially during the dry season. In formulating a rehabilitation program for areas affected by forest and land fires, one of the information needed is the fire severity level. The fire severity assessment method has not been integrated with any system or database; those who need it cannot access the assessment data. Therefore, this research aims to build a Post Forest and Land Fire Area Severity Level Assessment System, specifically the front-end module. The front-end development is carried out by adopting the prototyping method, which includes the stages of communication with stakeholders, quick system planning and modeling, prototype construction, testing and system feedback. Key features provided by the front-end module include account registration, login, viewing a map of post-fire locations, adding new post fire assessment, viewing detailed report data, modifying report data, deleting report data, and viewing user data. Results from black-box testing show that all key features in the front-end module performed as expected. The advantages of this front-end module include a feature to search for coordinates automatically, abillity to divide a post fire area into multiple plots, a feature to fix incorrect data entries after the report has been made, and a good performance. Plans to fix the system in the next development iteration include adding new user types and a user management module, adding a filter and a search feature, as well as adding an account verification mechanism.

Judul: Pengembangan Front End Sistem Informasi Manajemen Data Patroli Pencegahan Karhutla di Wilayah Sumatera
Abstrak: Kebakaran hutan dan lahan (karhutla) menyebabkan kerugian pada berbagai bidang di kehidupan masyarakat. Berbagai upaya dilakukan pemerintah untuk meminimalkan dampak permasalahan karhutla di Indonesia yang salah satunya adalah patroli terpadu karhutla. Aplikasi mobile patroli terpadu karhutla merupakan modul aplikasi yang mempermudah tim patroli dalam proses pelaporan data hasil observasi di lapangan. Penelitian ini bertujuan mengembangkan modul aplikasi web untuk monitoring data patroli dan manajemen data pengguna patroli karhutla. Pengembangan modul aplikasi web menggunakan metode prototyping dan diuji menggunakan metode blackbox. Tahapan dalam penelitian ini adalah komunikasi, perencanaan cepat, pemodelan rancangan cepat, konstruksi prototipe, dan terakhir penyebaran, penyampaian dan umpan balik. Modul aplikasi web diberi nama Sistem Informasi Patroli Pencegahan Kebakaran Hutan dan Lahan. Hasil pengujian menunjukkan bahwa modul aplikasi web dapat bekerja dengan baik, dan sesuai dengan kebutuhan pihak manajemen aplikasi mobile patroli pencegahan karhutla, Forest and land fires (karhutla) cause losses in various fields of people's lives. Various efforts have been made by the government to minimize the impact of forest and land fire problems in Indonesia, one of which is the integrated forest and land fire patrol. The integrated karhutla patrol mobile application is an application module that can make it easier for the patrol team in the process of reporting data from field observations. This study aims to develop a web application module for monitoring patrol data and data management for forest and land fire patrol users. Development of the web application module used the prototyping method and tested using the blackbox method. The stages in this research are communication, rapid planning, rapid design modelling, construction prototyping, and finally dissemination, delivery and feedback. The web application module is named the Forest and Land Fire Prevention Patrol Information System. Test results show that the web application module can work well, and meets the requirement of the mobile application management of karhutla prevention patrol

Judul: Optimization of Alginate-Chitosan Microcapsules Formation for Leydig Cells Encapsulation
Abstrak: Hypogonadism is a clinical condition characterized by low concentrations of testosterone. It is caused by malfunction of Leydig cells in producing testosterone. Encapsulation method will protect the transplanted cells from the immune system rejection. The aims of this study was to optimize the formation of microcapsules for Leydig cells encapsulation. The microcapsules were made of alginate and chitosan as the first and the second coating agents, respectively. The result showed that the minimum concentration of alginate was 1.5% (w/v) with a viscosity of 33.8 cPs, resulted spherical microcapsules with diameters of 230-270 µm. The optimum concentration of chitosan as the second coating agent was 0.5% (w/v), resulted spherical microcapsule with mechanical stability in 4 hours. Leydig cells can be trapped inside the capsule with a density that proportional with concentration of cells used in the encapsulation.
