The process of representing the distribution of larva free numbers in the district of Kediri which is not visible makes the monitoring process for larva free rates per region less effective and efficient. Therefore, a geographic information system is needed to describe the distribution of larva free numbers in the Kediri Regency area. The design and development of this information system is carried out using two methods, one of which is the data collection method by conducting interviews with one of the staff in the Kediri district Health Office, observing and looking for references related to research.The existence of a Geographical Information System for the Distribution of Larva Free Numbers, helps the Kediri District Health Office in terms of recapitulating data and monitoring the risk of the distribution of larva numbers in the Kediri Regency area. The Geographical Information System for the Distribution of Larva Free Numbers in Kediri Regency was successfully designed and built and can display the distribution of larva free numbers in the form of markers on a map. The Geographical Information System for the Distribution of Larva Free Numbers in Kediri Regency uses PHP, HTML, CSS, JavaScript, MySQL, and the laravel framework.

Tuberculosis (TB) is a chronic disease that is still a public health problem globally, including Indonesia, due to its easy transmission. Treatment for TB sufferers consist of several drug combinations that are intended to eradicate germs. For TB sufferers, the key to successful treatment is the patient's compliance with taking medication every day. The lengthy treatment time is usually at least six months allowing non-adherence to taking the medication by the patient. If not treated properly, there will be a risk of disease complications, such as tuberculosis bacteria resistant to drugs, making TB treatment more difficult. In this study, an Android-based was built to remind TB sufferers to take their medication during the treatment process. In addition to the mobile-based application, there is also a web application used by drug drinking supervisors (PMO; Petugas Minum Obat in Indonesia) in monitoring TB patients, where the application can also view patient compliance statistics in taking medication and historical data on TB patients’ medical treatment. After completion and development, the application will be given to PMO officers and patients to be tested. It is hoped that the application can help the TB treatment process become more effective and prevent treatment failure from the implementation.

The significant increase in COVID-19 cases in Indonesia in May-July 2021 overwhelmed health workers. One of the efforts to monitor the spread of COViD-19 disease is collecting data on patients and proper monitoring. For example, the Sukorame Community Health Center, Mojoroto Kediri, does not yet have an application to record and monitor COVID-19 patients. Data collection is currently done manually by writing in books and excel. This study designed and built a data collection and monitoring application for COVID-19 patients to help Puskesmas staff obtain more accurate patient data and monitor the related patient data. This study implements the waterfall method, including system requirements, design, implementation, verification, and maintenance. The results of this study are the applications that can help and facilitate Community Health Center in collecting data on COVID-19 as a form of effort in overcoming and preventing the spread of COVID-19 in the work area of Sukorame Community Health Center, Kediri City. Based on the user satisfaction questionnaire results, 75% of users consisting of staff and heads of community health centers were helped by this application.
