GREEN INFRASTRUCTURE IMPLEMENTATION TO INCREASE SUSTAINABILITY IN THE CITY OF SURABAYA (CASE STUDY: FLORA PARK)
Get PDFThe rapid development of cities not only has an impact on the improvement of economic aspects, but also brings quite serious problems, especially the decline in environmental quality. To ensure that the condition of the urban environment is maintained, regulations are implemented, one of which regulates the availability of green open space. This regulation comes under the aim of limiting the built-up areas in urban areas so that open spaces can be used for planting and can be made available to the public for social and recreational activities. Objectives: The objective of this study was to identify the application of green infrastructure as part of the green open space in Surabaya. Methodology and results: The method used in this research is descriptive qualitative by collecting data directly through field observation or indirectly through literature study. The location taken for this research was Flora Park in Surabaya. The results of the observations show that the park implements well the green infrastructure concept such as the use of environmental paving block, perforated pipes, xeriscaping, rainwater harvesting, tree canopy, reservoir, and supportive waste management system. Conclusion, significance and impact study: It is important to pay attention to the maintenance of the park so that it remains align with its function and use
ASSESSING GROUNDWATER QUALITY IN NORTH JAKARTA: A STATISTICAL APPROACH
No full textAims: This study investigates the groundwater quality in North Jakarta. Methodology and results: The groundwater data from thirty-one sampling sites were analyzed for physical and chemical parameters such as total dissolved solids (TDS), pH, turbidity, nitrate (NO3), sulfate (SO4), chloride (Cl), manganese (Mn), fluoride (F), and iron (Fe). Principal Component Analysis (PCA) and Spearman’s correlation matrix were utilized to evaluate the contamination sources. Conclusion, significance, and impact study: The findings reveal significant variability in chloride and total dissolved solids (TDS) concentrations, while fluoride levels remained stable. Strong correlations were found between TDS and chloride, as well as, turbidity and iron, suggesting contamination from seawater intrusion and industrial activities. PCA identified four key components explaining 77% of the total variance. The first component, dominated by TDS, turbidity, iron, and chlorine, indicates ongoing seawater infiltration in the coastal aquifer. The second component, associated with turbidity, nitrate, and fluoride, indicates contamination from human activities. This study shows the value of multivariate statistical techniques like PCA, in assessing groundwater quality. The correlation matrix further confirms the influence of seawater on groundwater salinity and the presence of heavy metals, possibly due to soil disturbance. Moreover, there is an influence of geological and geographical factors, particularly the excessive groundwater extraction leading to seawater intrusion and groundwater quality deterioration.

Putusan No. 2017.6.16. 2015 Gadan memutus bahwa anak luar kawin yang tebukti berdasarkan hasil genetik berhak mewarisi harta milik ayahnya. Sedangkan dalam Putusan Nomor 533/Pdt.G/2010/PN.MDN Jo. Putusan Nomor 84/Pdt/2012/PT.MDN menolak permohonan Penggugat karena Penggugat bukan merupakan bagian dari ahli waris yang sah dari Pewaris.Inheritance issues are complex, and international marriages further complicate matters due to the pluralism of legal systems between countries. This study compares the inheritance systems for children born out of wedlock in South Korea and Indonesia. In Indonesia, inheritance is regulated by customary law, religious law (Islamic law), and the Civil Code (KUHPerdata), granting inheritance rights to children born out of wedlock based on the parents\u27 marital status. In South Korea, the Civil Act governs inheritance for children born out of wedlock with some restrictions. The study finds that in South Korea, inheritance for children born out of wedlock is regulated by Article 855 of the Korean Civil Code, while in Indonesia, it is governed by Article 280 of the Civil Code. In case No. 2017.6.16. 2015 Gadan, the court ruled that a child born out of wedlock, proven through genetic testing, has the right to inherit the father’s property. In contrast, Decision No. 533/Pdt.G/2010/PN.MDN Jo. Decision No. 84/Pdt/2012/PT.MDN rejected the plaintiff’s claim because they were not considered a legitimate hei
OTORITAS JASA KEUANGAN DALAM SISTEM KETATANEGARAAN INDONESIA: The Financial Services Authority in the Indonesian State System
No full textLembaga jasa keuangan yang mempunyai beragam subsektor keuangan (konglomerasi) sudah meningkatkan kompleksitas transaksi dan interaksi di dalam sistem keuangan. Lembaga negara baru salah satunya dimunculkan sebagai lembaga negara independen (auxiliary state organ) yaitu Otoritas Jasa Keuangan (OJK). Rumusan masalah yang diajukan Apakah Otoritas Jasa Keuangan sudah independen dalam melangsungkan wewenang dan tugasnya selaras pada Undang-Undang Nomor 21 tahun 2011? Bagaimana posisi OJK dalam struktur ketatanegaraan Indonesia? Penulisan ini memakai metode tipe penelitian normatif yang bersifat penelitian deskriptif dan didukung oleh data sekunder, bersumber dari bahan hukum sekunder, primer, dan tersier. Berdasarkan analisis yang dilakukan, bisa disimpulkan bahwa OJK independensinya tidak sepenuhnya murni karena terikat oleh hukum, regulasi, dan pengawasan badan eksternal seperti Badan Pemeriksa Keuangan (BPK) dan Dewan Perwakilan Rakyat (DPR). Kemudian OJK yakni lembaga negara bantu yang berperan dalam mengawasi dan mengevaluasi kinerja serta kebijakan untuk memastikan transparansi, akuntabilitas, dan mencegah penyalahgunaan wewenang, menjaga keseimbangan kekuasaan.
Financial institutions with ownership links across various financial subsectors (conglomerates) have increased the complexity of transactions and interactions among financial institutions within the financial system. One of the new independent state institutions introduced is the Financial Services Authority (OJK). The main issues raised are whether the OJK has been independent in carrying out its duties and authority in accordance with Law No. 21 of 2011, and what is the position of the OJK in Indonesia\u27s state structure? The method used in this is a normative research type with a descriptive research nature, supported by secondary data sourced from primary, secondary, and tertiary legal materials. The result and the concluded that the independence of the Financial Services Authority (OJK) is not fully pure, as it is bound by laws, regulations, and external oversight bodies such as the Financial Audit Agency (BPK) and the People’s Representative Council (DPR). Furthermore, the OJK is an auxiliary state institution that plays a role in overseeing and evaluating its performance and policies to ensure transparency, accountability, and prevent abuse of power, while maintaining a balance of power
