Abstract

Tembesu (Fagraea fragrans Roxb) merupakan jenis unggulan lokal di Sumatera Selatan. Pemanfaatannya yang sangat luas telah mengakibatkan menurunnya potensi jenis tersebut di hutan alam. Panjangnya daur tanaman tembesu  menjadi masalah dalam usaha budidaya tanaman tersebut. Salah satu upaya untuk mengatasi permasalahan tersebut adalah dengan pemuliaan tanaman. Penelitian ini bertujuan untuk mengetahui pertumbuhan tanaman dan variasi genetik uji keturunan tembesu (Fagraea Fragrans ROXB) umur 3 tahun di KHDTK Kemampo, Kabupaten Banyuasin Provinsi Sumatera Selatan. Penelitian ini menggunakan Rancangan Blok Tak Lengkap dengan baris kolom, 55 famili, 20 ulangan. Hasil penelitian menunjukkan bahwa Provenan berpengaruh tidak nyata terhadap semua variabel yang diamati, sedangkan family tanaman berpengaruh sangat nyata terhadap tinggi tanaman dan diameter batang serta berpengaruh nyata terhadap volume pohon. Rata-rata tanaman tertinggi  terdapat pada family 20 yaitu 4,79 m, rata-rata diameter terbesar terdapat pada family 35 yaitu 7,02 cm, rata-rata volume terbesar terdapat pada family 35 sebesar 0.0177 m3. Untuk parameter genetik, nilai heritabilitas individu berada pada level tinggi yaitu 0,37 untuk tinggi tanaman, dan berada pada level sedang untuk diameter batang dan volume pohon, sedangkan nilai heritabilitas famili berada pada level tinggi yaitu 0,65 untuk variabel tinggi tanaman dan berada pada level rendah untuk diameter batang dan volume pohon. Untuk korelasi genetik antara tinggi dan diameter batang mempunyai nilai yang tinggi yaitu 0,67 Taksiran perolehan genetik pada tingkat seleksi 5% menunjukkan nilai yang cukup tinggi yaitu 7,84% untuk tinggi tanaman, 4,51% untuk diameter batang, dan 36,62 untuk volume pohon.

Abstract

Research aimed to study dominant soil characteristics that effect on available K of smectitic soils were conducted in Laboratory of Research and Soil Test, Indonesian Soil Research Institute. The soil characteristics that has been analised were soil texture (pipette), organic-C (Kjeldahl), and CEC (NH4OAc); mineralogical analyses of clay fraction (X-Ray Diffraction); K fractionation: soil soluble-K (0.0002 M CaCl2), exchangeable-K (NH4OAc), and total-K (HNO3+HClO4); and potassium sorption. The results showed that the content of soil soluble, exchangeable, non-exchangeable, and total-K was in order of Vertisols > Alfisols > Inceptisols. The percentage of soil K fraction of the soils, however, was in order of soluble-K < exchangeable-K < non-exchangeable-K. Although the soils had high content in total K but most of them were in nonexchangeable form, thus they were not available for plant growth. Soil K buffering capacity and maximum sorption were in order of Vertisols > Alfisols > Inceptisols. The bond energy constant of Vertisols, however, was similar with that of Alfisols but it was about twice with that of Inceptisols. Soil clay, organic-C, and CEC affected the availability of soil K significantly (P > 0.95). Smectite contributed significantly (P > 0.95) to soil negative charge so that it held an important role in controlling soil K buffering capacity and maximum sorption. To increase the efficiency of K fertilizer, plant species that can produce organic acid exudated from roots in high quantity can be developed in smectitic soils. The use of Na, NH4, and Fe cations need also to be considered for K management in the soils as well.

Abstract

Perlindungan dan penegakan hukum di bidang kesehatan bagi masyarakat terlihat jelas masih sangat kurang, banyak masyarakat mengeluhkan tentang perlindungan terhadap kesehatan. Sehingga dalam kajian ini akan di bahas mengenai bagaimanakah perlindungan hukum terhadap layanan kesehatan masyarakat berdasarkan Undang-Undang Nomor 36 Tahun 2009 Tentang Kesehatan. Hukum kesehatan termasuk hukum “lex specialis”, melindungi secara khusus tugas profesi kesehatan (provider) dalam program pelayanan kesehatan manusia menuju ke arah tujuan deklarasi “health for all” dan perlindungan secara khusus terhadap pasien “receiver” untuk mendapatkan pelayanan kesehatan. Jenis penelitian ini adalah sosiologis, sehingga sumber data yang digunakan adalah data primer, data sekunder dari perpustakaan dan data tersier dari kamus, media, dan ensiklopedia. Teknik pengumpulan data dilakukan dengan observasi, wawancara, dan kajian kepustakaan

Abstract

Inclusive tourism emphasizes the principle of equal access to tourism facilities and infrastructure, ensuring that tourism benefits are accessible to all individuals, including persons with disabilities and marginalized communities, while simultaneously supporting environmental conservation and long-term sustainability. This study aims to explore the readiness of Pasir Padi Beach in implementing inclusive tourism by examining physical accessibility, such as adequate infrastructure, wheelchair-friendly pathways, and accessible transportation, as well as inclusive services, information availability, and social acceptance in developing a disability-friendly and sustainable tourism destination. This study adopts a qualitative research approach using a descriptive and exploratory design. Data were collected through in-depth interviews with key stakeholders, including local government officials, destination managers, tourism service providers, and community representatives. These data were complemented by direct field observations and document analysis related to tourism planning and accessibility policies. Qualitative data analysis was conducted using NVivo software to identify dominant themes, stakeholder perspectives, and institutional readiness related to inclusive tourism development. The findings indicate that Pasir Padi Beach has demonstrated initial commitment toward inclusive tourism; however, several gaps remain, particularly in standardized accessibility infrastructure, integrated planning, and public awareness regarding disability inclusion. The study further reveals that multi-stakeholder collaboration among government agencies, destination managers, local communities, and the private sector plays a decisive role in establishing an adaptive, inclusive, and equitable tourism system. Inclusive tourism development is found to contribute not only to social justice and equal participation but also to market diversification, destination competitiveness, and long-term sustainability. In conclusion, the development of inclusive tourism at Pasir Padi Beach requires a comprehensive, participatory, and sustainability-oriented approach. This study contributes to the growing body of inclusive tourism literature and supports the achievement of the Sustainable Development Goals (SDGs), particularly those related to equality, reduced inequalities, and sustainable cities and communities.
