Judul: Sistem Manajemen Pengetahuan Penyelesaian Kerugian Negara (Studi Kasus:LAPAN)
Abstrak: The management of state finance is one of important factors in 1945 Constitution since reformation on the management of state finance becomes the basic of its process in an orderly manner, transparently, and accountably. The reformation on the management of state finance in law is marked with three packages of Laws about State Finance, namely Law No. 17 Year 2003 about State Finance, Law No. 1 Year 2004 about State Treasury, and Law No. 15 Year 2004 about Examination of Management and Responsibility of State Finance. In the management of state finance, one of important factors regulated in those three packages of laws about the state finance are related to the state loss settlement. TPKN-LAPAN is the team formed based on the decision from chairman of LAPAN with the role to implement the management process of demand of treasury and compensation on the state loss in LAPAN based on the finding of Badan Pemeriksa Keuangan (BPK), Inspektorat of LAPAN, and report of work unit. The problems of state loss management in LAPAN are the importance of understanding on the state loss settlement in every work unit, the transfer of human resource as the management of state loss cases that is not followed by the transfer of knowledge, few source documents that hamper the state loss settlement, difficulty in knowing the stages of every case of state loss. Based on the aforementioned problem, it needs knowledge management system that is interaction of technology and mechanism to support the process of knowledge management. Web based application using the knowledge management system and utilize the current technology, so that any data, information and knowldege could be processed accurately and quickly accessible, and SIMAPKLA using it. This research aims to develop knowledge management system of the state loss settlement in LAPAN (SIMAPKLA). The used research methodology is Knowledge Management System Life Cycle (KMSLC) and usability engineering approach. KMSLC consists of six stages, evaluate existing infrastructure, form the KM team, knowledge capture, design KM blueprint, verify and validate the KM system, implement the KM system. The tacit, explicit knowledge is taken from the experts and it is stored in the Knowledge Base (KB). The design model uses the approach with the orientation of object. The system develop using yii framework with php programming language and database MySQL. Verification and validation using blackbox for test of the functionality and evaluation using use questionaire (Lund 2001). At the stage of implementation, the system will be installed to the server. On the administrator page there are four access levels. The access are created for chairman/vice chairman of TPKN that can manage articles and forum, for member of TPKN can create articles and manage forum, for secretariat of TPKN can manage profiles, news, agenda, TP/TGR, and for administrators have unlimited access. On the user page, users can search, download documents, and ask questions. ii Based on a several testcase, we can conclude that the system valid in terms of functionality. Based on use questionaire the score are US of 5.62, EU of 5.58, EL of 5.70, and SC of 5,52. The

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.
