Penelitian ini mengkaji transformasi jaringan perkotaan Kotabaru Yogyakarta melalui pendekatan tipomorfologis, dengan fokus pada ketahanan dan kemampuan beradaptasi elemen ruang di tengah perubahan perkotaan yang cepat. Awalnya dirancang berdasarkan konsep Garden City, Kotabaru telah mengalami transformasi signifikan, termasuk konversi zona perumahan menjadi penggunaan komersial, pengurangan ruang terbuka hijau, dan meningkatnya ketidakkonsistenan arsitektural. Menggunakan analisis spasial diachronis dari tahun 1925 hingga 2025, penelitian ini mengidentifikasi pergeseran morfologis kunci dan mengkategorikan elemen perkotaan menjadi tipe persisten, pendorong, dan patologis. Temuan menunjukkan bahwa meskipun beberapa struktur permanen, seperti jaringan jalan radial dan bangunan kolonial, tetap ada, mereka tidak cukup untuk mempertahankan idealisme Garden City di hadapan komersialisasi, tekanan populasi, dan tuntutan infrastruktur. Degradasi ruang hijau—dari 45,3% pada tahun 1925 menjadi 24,61% pada tahun 2025—lebih lanjut menyoroti hilangnya keseimbangan ekologi dan spasial. Studi ini menyimpulkan bahwa ketahanan jaringan perkotaan memerlukan lebih dari sekadar keabadian fisik; ia membutuhkan penegakan kebijakan yang konsisten, perlindungan ekologi, dan intervensi desain yang sensitif terhadap konteks. Temuan ini berkontribusi pada strategi revitalisasi berkelanjutan distrik perkotaan warisan di bawah tekanan modernisasi.

Hasil evaluasi menunjukkan bahwa model berhasil menangkap hubungan linier di antara variabel independen dan dependen, memperoleh nilai MAE = 0,509; MSE = 0,464; RMSE = 0,681; dan R² = 0,627. Hal ini menandakan bahwa sekitar 62,7 persen variasi harga rumah di wilayah Jabodetabek dapat dijelaskan oleh model tersebut.

Keterbatasan akses sumber listrik di wilayah terpencil atau situasi darurat sering kali menghambat ketersediaan daya bagi perangkat telekomunikasi. Penelitian ini bertujuan untuk merancang bangun alat pengisi daya (charger) hibrida yang mengintegrasikan penyimpanan energi kimia baterai dan konversi energi mekanik dinamo sebagai solusi alternatif. Metode penelitian menggunakan Research and Development (R&D) dengan pendekatan deskriptif kuantitatif untuk menguji stabilitas tegangan dan efektivitas pengisian daya. Prototipe dirancang menggunakan baterai 18650, dinamo 12V, dan modul regulator tegangan untuk menstabilkan luaran. Hasil pengujian menunjukkan bahwa integrasi regulator berhasil menstabilkan fluktuasi tegangan dinamo (rentang 5–12V) menjadi tegangan konstan 5V yang aman bagi ponsel. Pengujian efektivitas selama 15 menit menunjukkan kenaikan kapasitas baterai ponsel sebesar 5–10% pada mode baterai dan 2–4% pada mode dinamo. Disimpulkan bahwa meskipun mode dinamo memiliki efisiensi yang lebih rendah akibat variabilitas putaran manual, alat ini layak diimplementasikan sebagai solusi catu daya darurat (emergency kit) yang portabel, ekonomis, dan memiliki redundansi energi yang andal.

Indonesia has great potential in the use of geothermal energy as a source of renewable energy. However, its application at the household scale is still very limited. This study designed a geothermal energy conversion system using a shell and tube type heat exchanger that is optimized for domestic needs. This system uses an isopentane working fluid that has a low boiling point, thus allowing the efficient use of low-thermal heat for water and room heating. The simulation results show that this system has a high heat transfer efficiency, with an output temperature of up to 84°C.  Thus, this system has the potential to become an economical and environmentally friendly renewable energy solution for households.

This study examines the practice of marital property division at the Sibolga Religious Court due to divorce caused by the husband's religious conversion. The phenomenon of divorce due to religious differences, especially religious conversion from Islam, creates legal complexities, particularly in determining rights and obligations related to marital property. This study employs a qualitative approach with an empirical legal research type, located at the Sibolga Religious Court. Data was obtained through in-depth interviews with judges, court clerks, and parties involved in the cases, as well as document studies of court decisions. The results indicate that the Sibolga Religious Court has absolute authority in handling divorce cases due to the husband's religious conversion and the division of marital property within them. Despite the religious conversion, the principles of Islamic marital property law (syirkah) remain the primary basis, considering the contribution of each party. Challenges include the complexity of proving contributions, often emotional negotiations between parties, and judges' efforts to achieve substantive justice. The implications of the decisions not only involve legal aspects but also social and psychological ones for the families. This study recommends the need for broader legal socialization regarding rights and obligations in interfaith marriages and increased public understanding of marital property dispute resolution procedures.

Karena meningkatnya kebutuhan listrik masyarakat Indonesia setiap tahunnya, penelitian sedang dilakukan untuk mengubah energi matahari menjadi energi listrik yang ramah lingkungan melalui konversi panel surya yang menghasilkan arus searah (DC). Karena sebagian besar panel surya diletakkan dalam posisi statis atau tidak bergerak, kemampuannya dalam menyerap sinar matahari tidak maksimal. Dengan menggunakan solar tracking sumbu ganda, posisi panel surya harus selalu melacak pergerakan cahaya matahari guna memaksimalkan energi matahari. Untuk mengetahui cara terbaik dalam menyerap sinar matahari, penelitian ini akan membandingkan daya listrik yang dihasilkan panel surya dengan dan tanpa solar tracking (statis). Penelitian ini menggunakan metodologi komparatif untuk mengetahui perbedaan keluaran daya antara solar tracking dan panel surya statis. Tegangan (V) diukur dengan multimeter, dan arus (I) diukur dengan tang ampere. Empat sensor LDR digunakan pada pelacak surya ini untuk mendeteksi sinar matahari. Mikrokontroler Arduino membaca keluaran sensor LDR dan menyalurkannya ke motor servo yang menggerakkan panel surya. Pengujian menggunakan panel surya statis dan solar pelacak, serta pengumpulan data arus (Ampere) dan tegangan (Volt) selama delapan jam, mulai pukul 08.00 WIB hingga pukul 16.00 WIB. Berdasarkan hasil pengukuran tegangan dan arus diperoleh daya total (P) sebesar 6,30 W tanpa solar tracking (statis) dan 30,37 W dengan menggunakan solar tracking. Hasil perhitungan panel surya dengan solar tracking dan tanpa solar tracking memperoleh persentase arus sebesar 78,37% dan daya sebesar 79,26%. Hasil penelitian ini mengungkapkan bahwa panel surya dengan menggunakan solar tracking lebih efisien dan optimal dalam menyerap sinar matahari dibandingkan tanpa solar tracking (statis).

Pendaftaran Tanah secara Sporadik menurut Peraturan Pemerintah Nomor 24 Tahun 1997 tentang Pendaftaran Tanah merupakan pendaftaran hak atas tanah yang dilakukan oleh pemilik tanah untuk pertama kali (konversi). Pendaftaran tanah secara sporadik sangat baik dilakukan bagi tanah yang belum pernah didaftarkan agar supaya administrasi terhadap tanah yang ada di Indonesia ini menjadi lebih teratur lagi. Mengingat pentingnya sertipikat hak milik sebagai surat tanda bukti hak yang berlaku sebagai alat pembuktian yang kuat maka penulis tertarik untuk meneliti analisis yuridis pendaftaran hak atas tanah secara sporadik melalui konversi dalam mewujudkan kepastian hukum. Penelitian ini bersifat yuridis normatif, dengan sumber data primer dan sekunder. Sumber data primer diperoleh dari narasumber perangkat desa dan masyarakat, sedangkan data sekunder diperoleh dari pengetahuan dan penelaahan yang dilakukan di perpustakaan berupa karya ilmiah, konsep hukum, pandangan ahli hukum serta jurnal - jurnal yang berkaitan dengan analisis yuridis pendaftaran hak atas tanah secara sporadik melalui konversi dalam mewujudkan kepastian hukum di Kabupaten Semarang. Hasil analisis menunjukkan bahwa kegiatan pendaftaran tanah memiliki tujuan untuk menjamin kepastian hukum. Peraturan Pemerintah Nomor 24 Tahun 1997, merupakan bentuk pelaksanaan dari pendaftaran tanah yang bertujuan untuk memberikan kepastian hukum dan perlindungan hukum bagi pemegang hak atas tanah dengan alat bukti berupa sertipikat tanah. Kendala yang dihadapi dalam pendaftaran hak atas tanah secara sporadik melalui konversi : Faktor Kurangnya Sarana dan Prasarana, Kurang memahami fungsi dan kegunaan sertipikat, anggapan diperlukan waktu yang lama dalam pengurusan, anggapan alas hak atas tanah yang dimiliki sudah sangat kuat, Anggapan Masyarakat Diperlukan Biaya yang Mahal Untuk Melaksanakan Pendaftaran Tanah. Upaya dalam menghadapi kendala tersebut, dilakukan penyuluhan tentang pentingnya melakukan pendaftaran tanah, maka pemilik bidang tanah tersebut akan mendapatkan dokumen tanda bukti hak sebagai alat bukti kepemilikan atas tanah yang datanya dijamin kepastian Hukumnya. Pemerintah daerah Kabupaten Semarang juga sudah membangun membangun Mal Pelayanan Publik yang bertujuan untuk mempermudah dalam akses pendaftaran tanah.

This research aims to investigate the social action conversion process experienced by former drug addicts in Sijambi Village, Tanjung Balai. The case study method was used with a qualitative approach, involving in-depth interviews with a number of former drug addicts. The theory used in this research uses the theory of social action proposed by Max Weber which refers to the change or transformation of a social action from one form to another. The action conversion intended by this theory explains that social action involves a series of activities and interactions carried out by individuals or groups in society with the intention of achieving certain changes or influences. It includes active involvement in activities that have the potential to influence social norms, values, or structures. The research results show that the social action conversion process of former drug addicts in Sijambi Village involves several stages, starting from realizing there is a problem, having the motivation to change, to being involved in positive activities. First social action conversion Social action conversion is the process of changing individual or group behavior to be more positive and in line with social values. Lohan exemplifies this concept through her transformation from drug use and detrimental behavior.

Nemo fish (Amphiprion sp.) is a type of marine ornamental fish that is popular because it is unique in terms of color, shape and movement. Feed is a factor in the growth and survival process of nemo fish. The aim of this research was to determine feed adaptation to the efficiency and feed conversion of nemo fish seeds. The research used an experimental method using a Completely Randomized Design consisting of 3 treatments and 3 replications. Treatment A (silk worms), treatment B (pellets) and treatment C (combination of 70% silk worms and 30% pellets). The best absolute weight growth results were in treatment C, namely 0.33 grams, while the lowest were in treatment B, namely 0.28. The survival rate (SR) during maintenance in each treatment was 100%. The best feed efficiency was in treatment C at 16.17% and the best feed conversion ratio was in treatment C with the lowest conversion ratio value of 4.81. Based on the results of the research conducted, it was concluded that feed adaptation for nemo fish seeds did not have a real influence on the efficiency and feed conversion of nemo fish seeds (Sig. > 0.05).    

Sebelum tahun 1960, di Indonesia berlaku dualisme hukum pertanahan yaitu berlaku hukum-hukum tanah kolonial Belanda, tanah yang tunduk dan diatur hukum Perdata barat yang sering disebut tanah barat atau tanah Eropa. Didalam hukum perdata barat diatur mengenai hak barat, yang mana hak barat merupakan hak atas tanah bagi orang asing yang diatur dalam Undang-Undang. Hak atas tanah tersebut dibagi menjadi 4 (empat) macam yaitu hak Eigendom, hak Opstal, hak Erfpacht dan hak Gebruik. Setelah berlakunya Undang-Undang Pokok Agraria (UUPAhak tersebut dikonversi menjadi hak milik, hak guna bagunan, hak pakai, hak guna usaha. Dalam prakteknya terdapat masih adanya tumpang tindih Sertifikat Hak Milik (SHM), seperti hasil pada kasus Putusan Pengadilan Nomor 321/Pdt/G/2018/PN dimana terdapat dua Sertifikat Hak Milik (SHM) untuk satu obyek yang sama. Dengan adanya kasus tersebut, tujuan dari karya tulis ini untuk dapat melihat bagaimana penyelesaian terhadap sengketa kepemilikan pemegang hak atas tanah Eigendom Verponding setelah berlakunya hukum Agraria Nasional, Apa pertimbangan Hakim tentang sengketa kepemilikan pemegang  hak atas tanah barat Eigendom Verponding setelah berlakunya Undang-Undang Pokok Agraria tanah yang tanda bukti haknya tumpang tindih, dan bagaimana status kepemilikan bidang tanah barat Eigendom Verponding yang tanda bukti haknya setelah konversi menurut Undang-Undang Pokok Agraria. Penelitian ini menggunakan metode pendekatan yuridis normatif yang menekankan pendekatan hukum dengan melihat peraturan perundang-undangan, baik bahan hukum primer maupun sekunder, atau dengan melihat peraturan perundang-undangan yang berlaku untuk memecahkan masalah. Dari hasil penelitin ini diketahui jika penyelesaian sengketa berdasarkan putusan Pengadilan Negeri Semarang Nomor 321/Pdt/G./2018/PN adalah dengan memenangkan penggugat dikarenakan penggugat memiliki asal usul SHM yang berasal dari SHGB tahun 1984. Pertimbangan hakim Pengadilan Negeri Semarang atas putusan Nomor 321/Pdt/G./2018/PN adalah SHGB merupakan alas hak untuk dapat dilakukan peningkatan hak menjadi Sertifikat Hak Milik (SHM). Sehinga pemilik obyek yang mempunyai SHM dengan asal usul Sertifikat Hak Guna Bangunan(SHGB)  adalah pemilik yang sah.
