Abstract

Studies on the possible influence of physical environmental factors on extracellular b-glucanase production by Acremonium sp. IMI 383068 were undertaken, in particular to assess the role of varying agitation speed and pO2 levels, since these have been shown in other studiesto affect the yields of other fungal extracellular enzymes. The use of chemostat cultures in this present study meant that the possible influence of these two parameters on enzyme production could be controlled independently of each other and of growth rate. No other similar data on possible factors affecting fungal (1->3)- and (1->6)-b-glucanases are available in the literature, and therefore other fungal extracellular enzyme systems are used here as comparisons for this discussion. To investigate the possible relationship between enzyme production and culture morphology, the HGU values or branching frequencies of the fungal hyphae were assessed. Since substantial conidial production also occurred in these cultures of Acremonium sp. IMI 383068, it was not possible always to distinguish between mycelial branches that were true vegetative hyphae and those eventually forming the short tapered lateral conidiophores that characterize this strain. Hence HGU determinations include both of these two branch types, except where it was obvious that the branch in question was a conidiophore, adjudged by the presence of emerging conidia from it. The major findings of this study will be discused here which were mainly engaged to the relationship between production of (1->3)-b-glucanases and the growth of the fungus, where it was growth rate dependent, while that of the (1->6)-b-glucanase was growth rate independent. The production of  (1->3)-b-glucanases was shear sensitive and also depended on O2 availability in the culture medium. Based on the data from both batch and chemostat culture, it was found that there was no clear relationship between branching frequency of the fungal mycelium and b-glucanase production by the fungus.Keywords: b-glucanases, Acremonium, HGU, batch and chemostat, branching frequency

Abstract

Elections are the means to implement sovereignty of the people in order to  elect members of the House of Representatives, Regional Representatives Council, Local  Legislative  Council,  the  President  and  Vice  President.  Election  are    also meaningful for selecting the leader of the nation and the state (public officials) and as community control over board membership, President and Vice President to come. Election results are manifestation of popular sovereignty, which can lead to a dispute between organizer and election participants either political parties or individuals. The result of which can be challenged legally by election participant. The participant can also request the cancellation of the election result to the agency given with the authority to decide. Conceptually, the right institution to decide on election dispute is a special ad hoc election court. Constitutionally, dispute resolution of election result is intended to protect citizens' constitutional rights.

Abstract

Penyebaran wabah virus korona masih terus terjadi di berbagai negara. Indonesia adalah salah satu negara yang terpapar wabah, sehingga berdampak ke berbagai sektor kehidupan warganya. Presiden Jokowi menjawab berbagai kritikan terkait penanganan dan penanggulangan COVID-19 di Indonesia melalui wawancara khusus dengan Najwa Shibab dalam acara Mata Najwa di Trans 7 pada 23 April 2020. Dengan melakukan analisis retoris dan pendekatan restorasi citra Benoit, penelitian ini berusaha untuk melihat bagaimana strategi pesan pemerintah dalam menjawab berbagai tuduhan terkait COVID-19. Hasil penelitian menunjukkan Jokowi berusaha memoles citranya dengan melakukan beberapa strategi antara lain penyangkalan, serang penuduh, diferensiasi, kekalahan, kecelakaan, memperkuat, dan tindakan perbaikan. Jokowi dalam perbaikan citra pemerintah cenderung memakai strategi bertahana yakni memperbanyak strategi diferensiasi dan defeasibility, serta niat baik. Meski ada penyangkalan tetapi Jokowi juga menghindari menyerang para penuduhnya.

Abstract

Indonesia is the Unitary State. It is understood that within a unitary state, the central government operates a high state sovereignty. In order not to be arbitrary, the activities of the central government are supervised and limited by the constitution. The government which is divided from the Central Government to the Regional Government included Regional Autonomy therein, as well as the authority of the Regional Government, is on duty to manage the Regional Property. In carrying out its authority as an administrator of local property, there are still many abuses or omissions committed by the local government in operating its authority in managing regional property, such as the negligence of the Regional Assets, the misuse of authority in the revocation of rights already granted by the regional government on the right to use of local property, using local property for personal interest. In the management of regional property required planning, implementation, and supervision by the local government in accordance with applicable laws and regulations in the constitution.

Abstract

Integrity, good character, justice, and expert statesman of the constitution as the indicators to appoint Constitutional Judge should be taken into account by the Supreme Court, the House, and the President in the selection process. The cases of corruption named Akil Mochtar and Patrialis Akbar as the convicted and the suspected persons respectively should be regarded as an appropriate opportunity to evaluate law relating to the Constitutional Judges selection process in which it is not clearly defined in the Constitutional Court Act. To date, the law relating to selection is given to respective institutions where the Supreme Court takes the selection internally with no transparency, the House only requires to write and present article, and—in some cases—the President prefers to appoint with no adequate criteria. The article uses doctrinal research in addressing the case related to the current regulation on constitutional judge selection. It concludes that the Supreme Court, the House, and the President ignore the principles of transparency, participatory, objectivity, and accountability in the selection, including the possibility of resulting unqualified judge. The selection needs reconceptualization comprising the establishment of expert panel, unaffiliated candidate to a political party, and re-concept of selection mechanism. Keywords: Reconceptualization, Selection, Constitutional Judge

Abstract

Salah satu tanda bukti kepemilikan tanah bagi setiap warga Negara Indonesia adalah berupa sertifikat tanah. Arti Sertifikat menurut Pasal 32 Ayat (1) Peraturan Pemerintah Nomor 24 Tahun 1997 tentang Pendaftaran Tanah menjelaskan bahwa sebagai surat tanda bukti hak yang berlaku sebagai alat pembuktian yang kuat mengenai data fisik dan data yuridis yang termuat didalamnya, sepanjang data fisik dan data yuridis tersebut sesuai dengan data yang ada dalam surat ukur dan buku tanah hak yang bersangkutan. Jika ternyata suatu saat terjadi sertipikat tanah ini hilang atau rusak, maka bisa diterbitkan sertipikat pengganti dan subjek haknya sendiri juga sama. Dalam proses pembuatan sertipikat tanah maupun sertipikat pengganti, diusahakan dalam waktu yang singkat, namun tidak meninggalkan soal kecermatan dan ketelitian dalam penangannya. Sebab, apabila yang terjadi suatu kelalaian atau kesalahan maka timbul kegagalan dalam kepastian hukum mengenai hak-hak atas tanah. Badan Pertanahan Nasional selaku institusi yang berwewenang dalam pembatalan sertipikat hak milik atas tanah berhak melakukan pembatalan sertifikat yang telah mendapat putusan pengadilan yang sudah berkekuatan hukum. Hal ini dapat diindikasikan bahwa BPN telah melakukan kesalahan dari segi administratif dan prosedural dalam menerbitkan sertipikat.

Abstract

Pemerintah daerah memiliki peran dalam pemenuhan hak anak melalui ruang terbuka hijau sebagaimana tercantum dalam Undang-undang No. 26 Tahun 2007 tentang Penataan Ruang. Bahwa setidaknya pemerintah bisa memberikan sedikitnya 20% dari luasan wilayahnya untuk pemenuhan ruang terbuka hijau yang bisa digunakan oleh masyarakat dalam beraktivitas secara positif misalnya, di alun-alun kota. Penelitian ni menggunakan metode penelitian legal studies dimana mengungkap masalah yang ada di amasyarakat dengan kemudian memberikan solusi. Pada dasarnya dalam setiap upaya yang telah dilakukan oleh pemerintah telah mengarah pada pemenuhan hak ruang terbuka hijau baik publik mapun privat baik berupa regulasi maupun program-program yang pro terhadap kepentingan anak. Namun masih ada beberapa hal yang menjadi kendala dalam melaksanakan program karena masih belum maksimalnya partisipasi dari seluruh stakeholder terutama untuk kondisi di Kabupaten Jember, sedangkan untuk di Kabupaten Banyuwangi secara keseluruhan bisa dikategorikan sebagai pemerintah kabupaten yang secara partifsipatif dalam hal pemenuhan ruang terbuk ahijau bagi anak, karena hampir rata di setiap program yang dilaksanakan selalu melibatkan peran dari seluruh stakeholder terkait.Kata Kunci: Hak Anak; Ruang Terbuka Hijau; Penataan Ruang.Regional governments have a role in fulfilling children's rights through green open spaces as stated in Law no. 26 of 2007 concerning Spatial Planning. That at least the government can provide at least 20% of its territory to fulfill green open spaces that can be used by the community for positive activities, for example, in city squares. This research uses the legal studies research method which uncovers problems that exist in society and then provides solutions. Basically, every effort that has been made by the government has aimed at fulfilling the rights to green open spaces, both public and private, in the form of regulations and programs that are pro-child's interests. However, there are still several things that are obstacles in implementing the program because participation from all stakeholders is still not optimal, especially for conditions in Jember Regency, while Banyuwangi Regency as a whole can be categorized as a district government that is participatory in terms of providing green open space for children. because almost every program implemented always involves the role of all relevant stakeholders.Keywords: Children's Rights; Green open Space; Spatial Planning.

Abstract

Undang-Undang Dasar Negara Republik Indnesia Tahun 1945 menyebutkan bahwa bumi dan air dan kekayaan alam yang terkandung didalamnya dikuasai oleh negara dan dipergunakan untuk sebesar-besar kemakmuran rakyat, sebagai dasar kegiatan pembangunan untuk kepentingan umum. Undang-Undang Nomor 5 Tahun 1960 Pasal 6 menegaskan bahwa semua hak atas tanah mempunyai fungsi sosial, salah satunya yakni kegiatan perluasan ataupun penambahan tempat pemakaman umum. Dalam pelaksanaannya pemerintah kota harus melaksanakan tahapan-tahapan kegiatan pengadaan tanah bagi pembangunan untuk kepentingan umum sesuai Undang-Undang Nomor 2 Tahun 2012. Pemerintah dalam mewujudkan pembangunan yang berkelanjutan dengan memperhatikan berbagai pertimbangan dan kondisi dan juga sosialisasi kepada masyarakat diantaranya, masyarakat/warga. Sebab pada dasarnya tujuan pembangunan untuk kepentingan umum sendiri yakni untuk meningkatkan kualitas hidup manusia, meningkatkan kesejahteraan, serta pemenuhan kebutuhan masyarakat. Pembangunan yang berkelanjutan akan terwujud apabila antar elemen selanjutnya saling berkaitan sebab seyogyanya pembangunan untuk kepentingan umum sendiri mengedepankan kemanusiaan, keterbukaan, keadilan, kepastian, kesepakatan, keikutsertaan, kesejahteraan, keberlanjutan, dan keselarasan guna mewujudkan kemakmuran masyarakat dan terpenuhinya kebutuhan masyarakat. Artikel ini dibuat untuk mendeskripsikan tentang bagaimana tempat pemakaman umum semakin luas di Surabaya dan segala akibat hukum yang timbul oleh karenanya.Kata Kunci: Perluasan Tanah; Pemakaman Umum; Kepentingan Umum.Constitution of the Republic of Indonesia states that the land and water and natural resources contained therein are controlled by the state and used for the greatest welfare of the people, as the basis for development activities for the public interest. In Law No. 5/1960, Article 6 states that all land rights have a social function, one of which is the expansion or addition of public cemeteries. In its implementation, the city government must carry out the stages of land acquisition activities for development in the public interest in accordance with Law Number 2 of 2012. The government in realizing sustainable development takes into account various considerations and conditions as well as socialization to the community, including the community / residents. Because basically the purpose of development is for the public interest itself, namely to improve the quality of human life, increase welfare, and fulfill the needs of the community. Sustainable development will be realized if the following elements are interrelated because development for the public interest itself should prioritize humanity, openness, justice, certainty, agreement, participation, welfare, sustainability and harmony in order to realize the prosperity of society and fulfill the needs of society.Keywords: Land Expansion; Public cemetery; Public interest.
