The enactment of Law Number 1 of 1974 concerning Marriage and KHI (Compilation of Islamic Law) is the answer to the problem of the uncertainty and the demands of the Muslim community to be a guide, and a reference in overcoming problems surrounding family law. In this paper, we will discuss the Political Concept of Islamic Family Law Legislation. This is important, because every policy or law issued by the government, at the same time there is a long political process so that the policy reaches the people. As it is known that not all juridical products are in line with the aspirations of the people. There are juridical products that are considered by the community to be contrary to the enforcement of democracy. One of the causes is the intervention of political interests in the internal power.</em></p> Jantarda Mauli Hutagalung Tantri Gloriawati Copyright (c) 2022 Jurnal Kajian Ilmiah 2023-01-23 2023-01-23 23 1 1 12 10.31599/jki.v23i1.932 Pengembangan Sistem Informasi Geografi Untuk Pemantauan Jaringan Irigasi Menggunakan LeafletJS https://ejurnal.ubharajaya.ac.id/index.php/JKI/article/view/1525 <p><em>The distribution or flow of water in irrigation networks that are not good can have an impact on air demand on agricultural land. This is due to the air volume that is not optimal due to damage to the irrigation network. Each irrigation network has a level of disturbance which is measured by the level of damage to the irrigation network based on the channel and building arrangement. Efforts to anticipate the level of damage to the wider irrigation network that can harm farmers, it is necessary to have a system that makes it easier for air interpreters to provide reports. Based on the report, the water interpreter will be followed up and processed by the team regarding more handling. In the ease of reporting, water interpreters need a location-based reporting system. Therefore, the right approach in reporting damage to irrigation networks is using a geographic information system. With the development of internet communication, geographic information systems have been developed that can be implemented on smartphones with the Android operating system.</em></p> Sumarsono Sumarsono Choerun Asnawi Evy Kusumaningrum Dedy Hariyadi Copyright (c) 2022 Jurnal Kajian Ilmiah 2023-01-23 2023-01-23 23 1 13 22 Pengaruh Marketing Mix Dan Kualitas Pelayanan Terhadap Kepuasan Konsumen Mujigae Resto Bekasi https://ejurnal.ubharajaya.ac.id/index.php/JKI/article/view/1601 <p><em>This study aims to determine whether the marketing mix has an effect on consumer satisfaction at mujigae restaurants, whether service quality affects customer satisfaction at mujigae restaurants, and whether both have an effect on customer satisfaction at mujigae restaurants.
