Judul: Development of Back-End Application for KMS KNPKI Based on RESTful API Using Prototyping Method
Abstrak: Keluarga memiliki peran krusial dalam membentuk individu dan masyarakat, dengan ketahanan keluarga menjadi aspek penting yang mempengaruhi kesejahteraan dan kebahagiaan keluarga. Koalisi Nasional Perlindungan Keluarga Indonesia (KNPKI) hadir sebagai respons terhadap tantangan dan masalah yang dihadapi oleh keluarga Indonesia, dengan fokus pada optimalisasi sumberdaya pembangunan ketahanan keluarga. Dengan lima pilar utama dan empat strategi, KNPKI berupaya mempercepat pembangunan ketahanan keluarga melalui berbagai platform seperti website resmi dan aplikasi seluler FamLink. Untuk mendukung kegiatan mereka, pengembangan aplikasi Knowledge Management System (KMS) menjadi suatu kebutuhan dalam melakukan manajemen pengetahuan yang dimilikinya sehingga pemahaman pengetahuan tersebut dapat disebarluaskan kepada masyarakat luas. Pengembangan ini bertujuan untuk melakukan pengembangan akan kebutuhan untuk KNPKI yaitu sebuah aplikasi KMS. Metode pada pengembangan ini adalah metode prototyping dengan tahapan komunikasi, perencanaan cepat, pemodelan perencanaan cepat, pengembangan prototipe, serta penyebaran dan umpan balik. Pengembangan berhasil dilakukan dengan memberikan pengelolaan artikel, dimana artikel dapat disebarluaskan kepada masyarakat luas sehingga ilmu tersebut dapat dipahami secara luas. Juga didalamnya terdapat dokumen jurnal yang dapat diunduh untuk dipahami secara detail. Selain Artikel, ada juga fitur pengelolaan Quote (kutipan) yang berisikan pemikiran-pemikiran pada para peneliti pada KNPKI. Pengujian pada proses pengembangannya juga berhasil dilakukan dengan melakukan unit testing yang dapat mencakupi seluruh alur logika kode sebanyak 100%. Pengujian secara black box testing juga telah memenuhi harapan dan seluruh umpan balik yang didapatkan., Families have a crucial role in shaping individuals and society, with family resilience being an important aspect that affects family welfare and happiness. The National Coalition for the Protection of Indonesian Families (KNPKI) comes as a response to the challenges and problems faced by Indonesian families, with a focus on optimizing family resilience development resources. With five main pillars and four strategies, KNPKI seeks to accelerate the development of family resilience through various platforms such as the official website and FamLink mobile application. To support their activities, the development of a Knowledge Management System (KMS) application is a necessity in conducting knowledge management so that the understanding of this knowledge can be disseminated to the wider community. This development aims to develop the needs for KNPKI, namely a KMS application. The method in this development is the prototyping method with the stages of communication, quick plan, modeling quick design, construction of prototype, also deployment delivery and feedback. The development was successful by providing article management, where articles can be disseminated to the wider community so that the knowledge can be widely understood. There are also journal documents that can be downloaded to understand in detail. In addition to Articles, there is also a Quote management feature which contains thoughts on researchers at KNPKI. Testing in the development process was also successfully carried out by conducting unit testing which can cover the entire logic flow of the code as much as 100%. Black box testing has also fulfilled expectations and all feedback obtained.

Judul: Back-End Development of Education, Consultation, and Jejaring Services FamLink Application Using the Prototyping Method
Abstrak: Ketahanan keluarga menjadi indikator penting yang mencirikan kemampuan suatu keluarga dalam mengatur sumber daya dan mengatasi seluruh permasalahan yang muncul. Semakin baik ketahanan keluarga, semakin mampu membangun lingkungan harmonis dan mencetak generasi penerus bangsa yang berkualitas. Pandemi COVID-19 menimbulkan masalah yang mengancam ketahanan keluarga seperti ketidaktahanan pangan, stres, hingga tekanan ekonomi. Hal ini dapat dicegah dengan deteksi dini, edukasi, dan konsultasi dengan pakar secara daring melalui sebuah aplikasi. FamLink telah hadir dengan serangkaian assessment untuk membantu keluarga Indonesia mempertahankan ketahanan keluarganya. Penelitian ini bertujuan mengembangkan modul back-end untuk tiga fitur baru yaitu edukasi, konsultasi dan jejaring pada aplikasi android FamLink serta mengembangkan beberapa modul pendukungnya pada situs web admin. Pengembangan dilakukan menggunakan metode prototyping dengan framework Laravel dan basis data MySQL. Pengembangan telah menghasilkan prototipe back-end sebanyak 47 endpoint API yang telah diuji menggunakan metode black-box serta lima modul pendukung fitur baru tersebut pada situs web admin., Family resilience is an important indicator that characterizes the ability of a family to manage resources and overcome all problems that arise. Families with good resilience will be able to build a harmonious environment and produce quality future generations. The COVID-19 pandemic has created various problems that threaten family resilience, such as food insecurity, stress, and economic pressure. Many families become vulnerable and fragile, resulting in crime and crisis in the family. This can be prevented through early detection, education, and consultation with online experts through the application. FamLink has come up with a series of assessments to help Indonesian families maintain their family resilience. This study aims to develop a back-end module for three new features, namely education, consulting, and jejaring on the FamLink android application, and develop several supporting modules on the admin website. The development is carried out using the prototyping method with the Laravel framework and MySQL database. The development has produced a back-end prototype of 47 API endpoints that have been tested using the black-box method as well as five modules that support the new feature on the admin website.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
