Mekanisme Pengaturan Dan Perencanaan Pembangunan Melalui Penggunan Ecobrick Dalam Pembangunan Infrastruktur Guna Mewujudkan Pembangunan Berkelanjutan
Nowadays, the accumulation of waste has become a major environmental problem in the social dynamics of Indonesian society. The issue of waste pollution, originating from industrial activities or household activities, has become a common problem. Therefore, a waste management mechanism is needed to support sustainable development for both society and the environment. This can be realized through the regulation and planning of infrastructure development using ecobricks. The implementation of ecobricks aligns with the government's sustainable development goals outlined in its planning system. The concept of ecobricks is a recycling mechanism that transforms waste into environmentally friendly bricks, optimally supporting sustainable development in society. To ensure the concrete implementation of this mechanism, this paper employs normative juridical research methods with a legislative and conceptual approach. Based on our research and findings, the implementation of ecobricks will involve collaboration between the government and the private sector, creating new job opportunities and providing livelihoods for the community. Moreover, the ecobrick mechanism will engage various environmental communities to foster social habits related to waste management. Thus, the ecobrick mechanism can address waste problems in Indonesia from upstream to downstream, effectively achieving sustainable development in the country.

UJI EFEKTIVITAS ANTIBAKTERI EKSTRAK NIGELLA SATIVA L. TERHADAP BAKTERI ESCHERICHIA COLI SECARA IN VITRO
Abstract—Infectious diseases remain a significant public health problem. One infectious disease can be caused by Escherichia coli. However, currently there is increasing resistance of Escherichia coli to several antibiotics. This has led to an increase in demand to develop new antibiotics that can overcome the development of resistance. Medicinal plants have enormous potential in the discovery of bioactive compounds that can fight resistant microorganisms. Nigella sativa L. is one such medicinal plant known for its antibacterial properties. The seed extract of Nigella sativa L. was obtained using the maceration method, resulting in four different concentrations: 12.5%, 25%, 50%, and 100%. These extracts were tested against Escherichia coli bacteria isolated on Mueller Hinton Agar media using the disk diffusion method. Nigella sativa L. seed extract with aquadest solvent produced average inhibition zone diameters of 0mm; 0mm; 0mm; 7mm, while with n-hexane solvent it produced average inhibition zone diameters of 0mm; 0mm; 0mm; 8.375mm at concentrations of 12.5%; 25%; 50%; 100%. The antibacterial activity of Nigella sativa L. seed extract was most effective at 100% concentration for both solvents. This study found no significant difference in antibacterial effectiveness between the aquadest and n-hexane solvent extracts of Nigella sativa L. against Escherichia coli.

Acne vulgaris merupakan peradangan unit polisebasea yang sering dikaitkan dengan infeksi Cutibacterium acnes (C. acnes). Penggunaan antibakteri topikal seperti klindamisin secara berlebihan telah menyebabkan resistensi C. acnes, sehingga diperlukan alternatif pengobatan. Minyak atsiri bunga lawang (Illicium verumHook. f.) mengandung trans-anetol yang diketahui memiliki aktivitas antibakteri, namun belum banyak diteliti terhadap C. acnes. Penelitian ini bertujuan untuk mengevaluasi aktivitas antibakteri minyak atsiri bunga lawang terhadap C. acnes, menentukan nilai Minimum Inhibitory Concentration (MIC) dan Minimum Bactericidal Concentration (MBC), serta mengembangkan formula serum topikal yang optimal dan efektivitas antibakteri serum minyak atsiri bunga lawang. Metode yang digunakan meliputi uji difusi agar dan makrodilusi. Kontrol positif berupa gel 1% klindamisin, sedangkan kontrol negatif menggunakan DMSO 100% dan formula tanpa minyak atsiri. Minyak atsiri konsentrasi 100% menunjukkan zona hambat terbesar 12,875 ± 0,609 mm. MIC tercatat sebesar 1,56%, sedangkan MBC >25%. Formula serum terbaik adalah F2 yang mengandung 5% minyak atsiri, dengan hasil evaluasi mutu organoleptis berupa cair agak kental berwarna putih dengan aroma khas bunga lawang, homogen, pH 4,947, tipe emulsi m/a, belum memenuhi syarat untuk viskositas dan daya sebar serta mempunyai zona hambat 7,558 ± 0,319 mm. Hasil ini menunjukkan potensi minyak atsiri sebagai antibakteri alternatif dalam pengobatan jerawat.
Acne vulgaris is an inflammatory condition of the pilosebaceous unit frequently associated with Cutibacterium acnes (C. acnes) infection. Excessive use of topical antibiotics such as clindamycin has led to the emergence of resistant C. acnes strains, necessitating alternative therapeutic approaches. Illicium verum essential oil, known for its high trans-anethole content, possesses antibacterial properties, though its efficacy against C. acnes remains underexplored. This study aims to evaluate the antibacterial activity of I. verum essential oil against C. acnes, determine its Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC), and develop an optimized topical serum formulation. Antibacterial activity was assessed using agar diffusion and macro-dilution methods. A 1% clindamycin gel served as the positive control, while 100% DMSO and a base formulation without essential oil were used as negative controls. The 100% essential oil exhibited the largest inhibition zone (12.875 ± 0.609 mm), with an MIC of 1.56% and MBC >25%. The optimal serum formulation (F2) contained 5% essential oil and showed desirable organoleptic properties, pH 4.947, oil-in-water emulsion type, though it did not meet the criteria for viscosity and spreadability. Its antibacterial zone was 7.558 ± 0.319 mm. These findings indicate the potential of I. verum essential oil as an alternative antibacterial agent for acne treatment.

Congenital Basal Meningocele: An Unusual Cause of Nasal Obstruction in Early Life
Abstract— Basal meningoceles are rare congenital defects that can cause nasal obstruction and often clinically occult until they result in life-threatening complications. Knowing the clues to early diagnosis, management, and complications is essential. Case: A 7-day-old baby girl was referred to our hospital because of high fever and dyspnoea, and the baby was diagnosed with pneumonia, lip tie, cup ears and suspicion of laryngomalacia. The patient got dyspnoea with stridor when drinking, and it decreased when her mouth was open. The suction catheter could not enter through the left choana. The nasal endoscopy showed an elevation of the hard palate. A 3-dimensional facial CT scan demonstrated a transsellar–transsphenoidal meningocele protruding into the left nasal cavity. A diluted liquid came out from the left nose with a yellowish-clear colour, and the baby showed a high-pitched cry. Bacterial meningitis was established from cerebrospinal liquor analyses. After meningitis treatment, surgical repair to meningocele reposition and bone defect repair was done at 40 days. Conclusion: In our case, the nasal obstruction was not detected from the beginning of birth, and it led to delays in finding the cause. Basal meningocele in this case was accidentally diagnosed by a facial CT scan exploring the cause of choana atresia. It’s essential to detect choana atresia since birth, explore the etiology immediately, and manage it well to prevent life-threatening complications.

Abstrak—Meningocele basal merupakan kelainan kongenital langka yang dapat menyebabkan obstruksi hidung yang secara klinis sering tersembunyi sehingga baru diketahui saat sudah terjadi komplikasi. Oleh karena itu sangat penting untuk mengetahui cara menegakkan diagnosis dini agar dapat diberi tata laksana yang tepat untuk mencegah terjadinya komplikasi yang mengancam nyawa. Kasus: Seorang bayi perempuan berusia 7 hari dirujuk ke rumah sakit kami karena demam tinggi dan dispnoea dan bayi itu didiagnosis sebagai pneumonia, ikatan bibir, telinga cangkir dan kecurigaan laringomalesia. Pasien mengalami dispnea dengan stridor saat minum; dan menurun ketika mulutnya terbuka. Kateter hisap tidak bisa masuk melalui choana kiri. Endoskopi hidung menunjukkan peningkatan langit-langit keras. CT scan wajah 3 dimensi menunjukkan transsellar – meningocele transsphenoidal yang menonjol ke dalam rongga hidung kiri. Cairan encer keluar dari hidung kiri dengan warna bening kekuningan, dan bayi itu menunjukkan tangisan nada tinggi. Meningitis bakteri ditetapkan dari analisis cairan serebrospinal. Setelah meningitis diobati, perbaikan bedah reposisi meningocele dan perbaikan cacat tulang dilakukan pada usia 40 hari. Kesimpulan: Dalam kasus kami, meningocele basal secara tidak sengaja didiagnosis dengan CT scan wajah yang mengeksplorasi penyebab choana atresia. Sangat penting untuk mendeteksi choana atresia sejak lahir, segera mengeksplorasi etiologinya, dan mengelolanya dengan baik untuk mencegah komplikasi yang mengancam jiwa.

Perlindungan Data Pribadi Klien pada Era Digital: Harmonisasi Regulasi Kenotariatan dan Hukum Perlindungan Data Pribadi
In line with the rapid advancement of technology in the digital era, notaries have also begun using technological tools such as computers to create deeds. Nowadays, notaries face challenges in maintaining the security of their clients' data storage from digital threats such as computer viruses, data breaches and modifications, and even misuse of electronic signatures. Furthermore, personal electronic data is also vulnerable to hacking by irresponsible parties. This research aims to understand the regulation of personal data protection in Indonesia, particularly regarding the rights and obligations of notaries in managing their clients' data, as well as the legal-political relation of notarial regulations in ensuring the protection of clients' data, as viewed from the Notary Law. The research method used by the author is a normative juridical method through literature studies. In the era of information technology development, personal data protection becomes very important, especially in notarial practices involving legal documents that are private and sensitive. In addition to the Personal Data Protection Law, the Notary Law is also expected to provide a legal foundation to maintain the confidentiality and security of notary clients' data. Therefore, synchronization between the Notary Law and Personal Data Protection Law have its urgency, although both regulations have the same objective to protect client’s data, there is a need to synchronize them so that there is no overlap in their implementation
