Abstract

Kabupaten Rembang merupakan wilayah yang secara langsung menerima dampak dari aktivitas erosi akibat arus dan gelombang. Erosi memiliki sifat merusak yang dapat  menganggu keseimbangan ekosistem dan dapat merusak infrastruktur yang telah dibangun pada daerah tersebut dan daerah sekitarnya. Tujuan dari kajian ini adalah untuk mengetahui pengaruh mangrove terhadap tingkat kerentanan pantai dan untuk memetakan Indeks Kerentanan Pantai berdasarkan pada lima variabel yang digunakan yaitu: tipologi pantai, geomorfologi pantai, vegetasi mangrove, kemiringan pantai dan penggunaan  lahan pesisir. Terdapat empat kelas kerentanan pantai di Kabupaten Rembang yaitu rendah, sedang, tinggi dan sangat tinggi. Pengaruh Mangrove untuk Kecamatan Kaliori tidak terlalu tampak, sedangkan di Kecamatan Rembang terjadi perubahan nilai kerentanan pantai dari tingkat kerentanan rendah menjadi tingkat kerentanan sedang.

Abstract

Shoreline deformation is a result from sediment transport process with an intervention of current. Concept of sediment cell used to facilitate the analysis and it can be seen on satellite images Landsat. The purpose of this research is to identify sediment cell limit and dominant direction of sediment transport along shore, erosion and sedimentation analysis using sediment cell approachment based satellite images analysis and wave modeling. This research used remote sensing method to determine sediment cell limit and ground check method to identify the source, direction and limits of sediments movement. The landmass that got erosion and accretion was obtained from satellite images overlay. Satellite images which used in this research is Landsat 1990, 2000 and 2010. According to the result of overlay, seashore deformation for 20 years was dominated by accretion (167,71 ha wider than erosion). The result of overlay showed that average accretion rate was 8,3855 ha/year and average erosion rate was 1,1745 ha/year. Results of overlay processing based on erosion and accretion showed that seashore in Bandar Lampung divided into 6 sub sediment cell with 5 limit of static sub cell and 1 dynamic sub cell appropriate for cell sediment concept.

Abstract

ABSTRAK: Pemetaan kerusakan terumbu karang akibat kandasnya kapal tongkang di P. Tengah dan di P. Cilik, Taman Nasional Karimunjawa, Jawa Tengah telah dilakukan 2-3 bulan setelah kejadian dengan cara mengukur luas area kerusakan dan menilai kondisi terumbu karang. Pengukuran area kerusakan menggunakan metode penginderaan jarak jauh berbasis Drone (UAV Drone/pesawat tanpa awak) dan penilaian kondisi ekosistem terumbu karang dengan menggunakan metode Underwater Photo Transect (UPT). Tujuan penelitian ini adalah untuk mengetahui kondisi dan kerusakan terumbu karang akibat kandasnya kapal tongkang di P. Cilik dan P. Tengah, Taman Nasional Karimunjawa. Hasil menunjukkan telah terjadi kerusakan fisik di lereng atas terumbu karang pada kedua pulau tersebut berupa karang mati dan pecahan karang. Luas kerusakan terumbu karang di P. Tengah (1.420,32 m2) lima kali lebih luas daripada luas kerusakan terumbu karang di P. Cilik (267,22 m2). Luasnya kerusakan terumbu karang di P. Tengah kemungkinan akibat perbedaan jumlah kapal tongkang yang kandas, waktu kandas dan dominasi karang yang mudah patah (fragile). Komunitas karang keras yang dominan di lereng terumbu P. Tengah adalah karang bercabang (CB), Acropora bercabang (ACB) dan karang lembaran/foliose (CF). Luasan kerusakan dan kondisi terumbu karang akibat kandasnya kapal tongkang ini dapat digunakan untuk pengelola kawasan konservasi dalam perencanaan perlindungan dan restorasi ekosistem terumbu karang di Taman Nasional Karimunjawa  ABSTRACT: Mapping damage to coral reefs due to the barges grounding in Cilik Island (P. Cilik) and Tengah Island (P. Tengah), Karimunjawa National Park, Central Java was carried out 2-3 months after the event by measuring the extent of damage and coral reefs assessment. Damage area measurement using Drone (UAV Drone) based remote sensing and reef ecosystem assessment using the Underwater Photo Transect (UPT) method. The aim of this study was to determine the condition and damage of coral reefs due to the wrecking of barges in Cilik and Central P., Karimunjawa National Park The results show that physical damage has occurred on the upper slopes of coral reefs on both islands is dead coral and coral fragments. Damage to extensive coral reefs in P. Tengah (1,420.32 m2) is five times larger than extensive damage to coral reefs in P. Cilik (267.22 m2). Damage to coral reefs in P. Tengah may cause differences in the number of barges that ran aground, time of aground and the dominance of fragile corals the upper slopes of the coral reefs. The dominant hard coral communities on the upper slopes of P. Tengah reefs are generally composed the fragile corals, such as branching corals (CB), branching Acropora (ACB) and foliose corals (CF). Damage to coral reefs and the condition of the ecosystem caused by the aground of the barges can be used to manage conservation areas in the planning of conservation and restoration of coral reef ecosystems in the Karimunjawa National Park in near future.

Abstract

Rokan Hulu Regency, Riau Province, is one of the largest oil palm plantation centers in Indonesia. The large growth of palm oil plantations in recent years has threatened the existence of protected areas and increased deforestation rates. This study aims to (1) find out the extent of land use change in Rokan Hulu Regency in 2000-2012, (2) predict land use change in Rokan Hulu regency by 2030. This research uses Geographic Information System approach with prediction model of Cellular Automata (CA) Markov Chain. The driving factors of land use change as input of CA Markov Chain model consist of distance to road, distance to river, distance to disturbance area, distance to Plantation Forest, distance to Forest Clearance Permits and slope data. The results showed that the area of deforestation reached 60.38% from 2000 to 2012, mostly in the northeastern region of Rokan Hulu Regency. The prediction model of land use change has an accuracy of 68.15% based on the kappa index agreement (KIA). By 2030, the area of forest land in Rokan Hulu is predicted to be 3.13%

Abstract

This paper aims to analyze and develop research of Islamic law using the paradigm of Guba and Lincoln. The development of the research of Islamic law using Guba and Lincoln paradigm was carried out by adjusting the basic beliefs of each researcher. The ontology of the positivism paradigm is considered realism of naïve. The basic belief of the researcher to understand the rules is “what is written” so that it is textually understanding. The ontology of post-positivism paradigm is critical realism in which the basic beliefs of the researchers are not only textually but also contextually by considering situations and conditions in terms of Asbabun Nuzul and Asbabun Wurud. The ontology of the paradigm of critical theory is historical realism which formed by the factors of social, political, culture, economy, ethnic and genders. The ontology of constructivism realism is called relativism in which the understanding of the rules depends on the individual or group which hold multiple constructions. It means that if the basic belief of a researcher searches through diverse opinions and thought, it has been in the constructivism paradigm. Therefore, the researchers of Islamic law should develop their researches through these various paradigms from the beginning to the end so that they will be guided to answer the research questions.

Abstract

Secara umum pembelaan (pledoi) oleh advokat adalah melindungi hak-hak tersangka/ terdakwa dari perlakuan sewenang-wenang oleh pihak yang tidak bertanggung jawab. Tujuan dari penelitian ini adalah mendeskripsikan pembelaan (pledoi) oleh advokat dengan menggunakan paradigma teori kritis Guba dan Lincoln bahwa posisi tersangka/ terdakwa tidak selalu salah tetapi dalil dakwaannya yang salah. Penggunaan paradigma didasarkan pada tiga pertanyaan, ontologi, epistemologi, dan metodologi. Advokat dan aturannya bersifat Interaktif; temuan di ‹mediasi› dengan nilai yang dipegang. Keduanya saling terkait secara interaktif dan kemudian dimediasi oleh nilai-nilai yang dianut oleh para advokat. Dengan demikian subjektivitas melalui nilai rasa, kreativitas, dan inisiatif advokat berpengaruh pada pembelaan (pledoi). Metodologinya adalah dialogis / dialektika. Penggunaan paradigma critical theory bagi para advokat, mereka harus memperjuangkan pihak-pihak yang terdominasi/ terzolimi untuk mengubah ketidakadilan atas berlakunya dalil-dalil dakwaan. Bagi mereka, aturan didasarkan pada keadilan formil, maka menjadi tugas advokat untuk menemukan keadilan substantif yang memungkinkannya berada di luar aturan. Hal inilah yang menjadi dasar pertimbangan hakim dalam memutuskan.
