Judul: Usability Testing System Information of Forest and Land Fires Patrol in Sumatera
Abstrak: Kementerian Lingkungan Hidup dan Kehutanan (KLHK) membentuk tim patroli yang bernama Manggala Agni untuk pencegahan kebakaran hutan dan lahan (karhutla). Tim tersebut menggunakan aplikasi yang bernama Sistem Informasi Patroli Pencegahan (SIPP) Karhutla. Aplikasi web SIPP Karhutla digunakan oleh tim manajerial dalam kegiatan patroli. SIPP Karhutla telah mengalami perubahan dan penambahan fitur, tetapi belum diuji fungsional dan usabilitasnya. Penelitian ini bertujuan untuk menguji usability web SIPP Karhutla. Sebelum pengujian usability, akan dilakukan black box testing. Metrics yang akan diukur pada pengujian usability adalah error dan efficiency. Seluruh skenario memiliki hasil sesuai yang diharapkan pada pengujian black box, kecuali filter data patroli pada menu analisis data. Hasil pengujian usability pada metrics task success menghasilkan tingkat keberhasilan di atas 75 persen kecuali pada skenario menu Patroli. Pada pengukuran efficiency masih terdapat skenario yang tidak responden selesaikan atau mengira selesai. Masalah yang ditemukan saat pengujian menghasilkan rekomendasi perbaikan dalam bentuk rancangan antarmuka., Ministry of Environment and Forestry established patrol teams Manggala Agni for forest and land fire prevention. The team uses the Forest and Land Fire Prevention Patrol System (SIPP Karhutla). The web version of SIPP karhutla is used by the managerial level in patrol activities. SIPP Karhutla has been changed and have new featuresbut the functional and usability of the system have not tested yet. This study aims to test the usability of SIPP Karhutla website. Black box testing was conducted before usability testing. Metrics that are measured in usability testing is error and efficiency. All scenarios in black box testing result the expected outputs except the filter data patrol feature in the data analysis menu. The result of usability testing in task success metrics is above 75 percent except for the patrol menu scenario. In efficiency measurement, there are scenarios in which the respondent did not complete and thinks that the scenario was done. Problems found in the testing produce improvement recommendation in user interface design.

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: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
