Abstract

Adsorpsi adalah proses pengumpulan suatu substansi pada permukaan padatan adsorben. Proses adsorpsi ini melibatkan dua komponen utama yaitu adsorben yang merupakan padatan dimana di atasnya terjadi pengumpulan substansi yang disisihkan dan adsorbat yaitu substansi yang akan disisihkan dari cairan. kadar mineral dapat menimbulkan efek gangguan terhadap kesehatan manusia, tergantung pada bagian mana dari kadar mineral tersebut yang terikat dalam tubuh serta besarnya dosis paparan. Pada penelitian ini dilakukan adsorpsi dengan proses aktivasi dan tanpa aktivasi sehingga dapat dilihat bahwa adsorben dengan proses aktivasi lebih efektif daripada adsorben tanpa aktivasi. Mineral Ca dan mineral Mg banyak terserap saat menggunakan adsorben dengan aktivasi dengan massa absorben sebesar 0,5 gram dikarenakan aktivasi dapat menyebabkan perluasan permukaan adsorben untuk menyerap kadar mineral. Sedangkan pada adsorben tanpa aktivasi hanya warna yang memudar untuk kandungan mineral dapat meningkat.

Abstract

Interviewing the respondents or informants. The method in this research is juridical empiric method. The result of this research shows that the legal regulation which influence the law enforcement towards Domestic Violence within the household is the Law No. 23 of 2004 on the eradication of Domestic Violence within the household. However, if before entering the litigation way, it is mediated in advance with the rule of Gampong and if a marriage is not recognized by the state so that the domestic violence is subjected to Article 351 of the Criminal Code. The law enforcer that influences the law enforcement against domestic violence within the household except the police, prosecutor, and court is (KPPPA). This institution also has an active role and is also involved to handle the domestic violence cases. Visumetrepertumis most important form of infrastructure and facilities and also becomes evidence in domestic violence cases. The societies who tend to be victims of domestic violence are women. The culture that influences law enforcement against domestic violence is patriarchal culture which strongly dominates in the household of the societies in Indonesia. As the Suggestion, in order to reach the realization of the effectiveness of law enforcement for domestic violence within the household so that the influenced factors should be better, especially for the State apparatus. They should conduct their duties properly.
PREPARASI DAN IDENTIFIKASI GARAM TEMBAGA(II): SINTESIS [Cu(NH₃)₄]SO₄·H₂O SEBAGAI GARAM KOMPLEKS DAN [CuNH₄)₂(SO₄)₂·6H₂O SEBAGAI GARAM RANGKAP Hermayantiningsih, Dwi; Hakim, Muh. Sunwatul; Manurung, Tety Wahyuningsih; Fiqih, Irvan Maulana; Zahra, Laila

Abstract

Penelitian ini bertujuan untuk membandingkan sintesis dan karakterisasi garam kompleks tetra amina tembaga(II) sulfat monohidrat ([Cu(NH₃)₄]SO₄·H₂O) dengan garam rangkap kupri amonium sulfat heksahidrat ([Cu(NH₄)₂(SO₄)₂·6H₂O]). Metode sintesis melibatkan kristalisasi dari larutan tembaga(II) sulfat pentahidrat (CuSO₄·5H₂O) dengan amonia berlebih untuk garam kompleks, dan pencampuran stoikiometris dengan amonium sulfat ((NH₄)₂SO₄) untuk garam rangkap. Hasil sintesis menunjukkan bahwa garam kompleks berwarna biru tua karena transisi elektronik d-d pada ion [Cu(NH₃)₄]²⁺ dengan geometri bidang persegi, sedangkan garam ganda berwarna biru muda karena lingkungan oktahedral [Cu(H₂O)₆]²⁺. Uji kelarutan dan stabilitas terhadap air suling dan NH₃ pekat mengungkapkan bahwa garam kompleks lebih rentan terhadap perubahan pH, menghasilkan endapan coklat tua (Cu⁰) saat dipanaskan, sedangkan garam ganda tetap stabil dengan warna biru muda yang persisten. Hasil sintesis garam ganda mencapai 91,765%, lebih tinggi daripada garam kompleks (75,804%), karena stabilitas termodinamika dan ketahanan terhadap disosiasi. Studi ini menyoroti perbedaan mendasar dalam sifat fisikokimia kedua senyawa, yang relevan untuk aplikasi bahan berbasis tembaga dalam industri dan kimia koordinasi.

Abstract

This study aims to determine the effectiveness of Sumedang Integrated ASN Information System (SIPANTES) in the Personnel and Human Resource Development Agency of Sumedang Regency. It is an information system built to meet the needs of personnel management in effective and efficient local government. The research method used is descriptive research using the qualitative analysis study approach. As for the data collection techniques used are librarianship studies and field studies (observation, interviews and documentation studies). Data analysis techniques use Sugiyono theory, data reduction, data display and conclusion drwing/verification. Informants in this study were determined using the purposive sampling method, which is 4 people. From the results of this study, SIPANTES in BKPSDM of Sumedang Regency has not reached the desired level of effectiveness. The main obstacles related to the management of personnel data that are still manual and the complexity of adding features to SIPANTES, which gave rise to complaints from some SKPD. To increase effectiveness, it is necessary to optimize the preparation for changes and the use of SIPANTES, with careful planning, involving all relevant parties, as well as the implementation of more intensive socialization and education. Thus, the positive potential of SIPANTES can be optimized to support more efficient personnel management in Sumedang Regency.
