Abstract

Serangkaian pengujian dilakukan untuk menentukan pengaruh penambahan fly ash limbah pembakaran batubara sebagai zat mineral tambahan (additive) terhadap perbaikan kualitas dan kuat tekan semen sesuai Standar Nasional Indonesia (SNI 15-2049-2004). Metode penelitian meliputi preparasi sampel, pembuatan semen dengan variasi fly ash 0%, 5%, 8%, 12%, dan 15%, uji sifat kimia dan fisika semen. Parameter yang diukur yaitu kadar komposisi kimia (%) menggunakan X-Ray Fluorescence Spectroscopy (XRF) ARL 9800 OASIS, kadar freelime (%) secara volumetri, kadar Insoluble Residue (%) secara gravimetri, kuat tekan (kg/cm2), dan kehalusan semen (cm2/g). Hasil penelitian menunjukkan bahwa penambahan fly ash meningkatkan kandungan SiO2 semen, sehingga memperbanyak senyawa C3S dan C2S yang merupakan komponen kuat tekan semen. Selain itu, penambahan fly ash berbanding lurus dengan kadar IR, kuat tekan, kehalusan, dan berbanding terbalik dengan kadar freelime. Sehingga penambahan fly ash dapat memperbaiki kualitas semen dengan menaikan komponen kimia, menaikan kuat tekan, dan mengurangi keretakan atau ekspansi semen.

Abstract

Women's representation in parliament has a very important role to convey the aspirations of society in general and women in particular. After the Constitutional Court Decision No. 22-24 / PUU-VI / 2008 there was a new regulation regarding the mandatory representation of women as much as 30% in parliament. However, until the 2019 elections were held, women's representation in parliament had not reached 30%. One of which reason women representation still under 30% is zipper system used in electoral system. Zipper system is an election system by placing male and female candidates intermittently. Indonesia applied a semi-pure zipper system with a proportion of 3: 1 and not a 1: 2 system. Therefore, the purpose of this study is to determine the opportunity of implementing zipper system in the upcoming 2024 election. This research is a normative juridical research using secondary data materials which are divided into three groups, namely primary legal materials in the form of laws and regulations, secondary legal materials in the form of articles and books that explain primary legal materials which are then presented qualitatively. In conclusion, looking at the pattern of Indonesian voters towards female candidates, the implementation of the zipper system with the 3:1 scheme applied in Indonesia can only increase the number of women's candidacy, not the number of electability. The dominance of young voters in the 2024 election can encourage women's electability with changes to the pure zipper system and political education about the importance of women's representation.

Abstract

Wakil menteri merupakan salah satu jabatan dalam struktural lembaga kementerian di Indonesia. Dalam penerapannya, jabatan wakil menteri tersebut mendapatkan problematika yaitu tumpang tindih kewenangan pejabat kementerian dalam menjalankan roda pemerintahan sebagai pembantu presiden dalam melaksanakan program kerjanya. Penelitian ini disusun untuk mengetahui bagaimana kedudukan wakil menteri sebelum dan sesudah adanya putusan MK Nomor 76/PUU-XVIII/2020. Penelitian ini dibentuk juga bertujuan untuk mengetahui kedudukan wakil menteri sebelum dan sesudah adanya Putusan MK Nomor 76/PUU-XVIII/2020. Penelitian ini menggunakan metode penelitian normatif yaitu penelitian hukum yang meletakkan hukum sebagai bangunan sistem norma. Pasca Putusan MK Nomor 76/PUU-XVII/2020, jabatan wakil menteri adalah setara kedudukannya dengan menteri, mengingat pengangkatan wakil menteri sama dengan menteri berdasarkan hak prerogatif presiden. Ketentuan demikian maka menguatkan dasar hukum bagi kedudukan wakil menteri yang sebelumnya tidak diatur secara rinci dalam Undang-Undang Nomor 39 Tahun 2008, akan tetapi justru wakil menteri kedudukannya diatur dalam Peraturan Presiden Nomor 60 Tahun 2012 Maka, pasca Putusan Mahkamah Konstitusi Nomor 76/PUU-XVIII/2020, wakil menteri berposisi sama dengan menteri karena adanya kesamaan dalam hal pengangkatannya berdasarkan hak prerogative presiden, yang mana sebelum adanya Putusan Mahkamah Konstitusi Nomor 76/PUU-XVIII/2020 wakil menteri berposisi setingkat dibawah yang didasarkan kepada Peraturan Presiden Nomor 60 Tahun 2012.
