Judul: Strategy for the Utilization of the Tanjungpinang Village Unit Cooperative Fish Landing Site as a Fish Landing Site
Abstrak: Pelantar Koperasi Unit Desa Tanjungpinang merupakan salah satu tempat pendaratan ikan hasil tangkapan di Kota Tanjungpinang. Pelantar ini memiliki potensi besar karena letaknya yang cukup strategis yaitu, lokasinya berdekatan antar pulau dan pasar. Namun potensi besar tersebut tidak bisa dimanfaatkan dengan baik karena masih sedikit kapal perikanan yang bersandar dan fungsinya tidak sesuai sebagai tempat pendaratan ikan, melainkan juga digunakan untuk mendaratkan penumpang dan barang-barang niaga. Berdasarkan permasalahan tersebut maka tujuan penelitian ini adalah mengidentifikasi kondisi aktual dan penyebab fungsi Pelantar Koperasi Unit Desa Tanjungpinang tidak sesuai dengan fungsinya sebagai tempat untuk aktivitas perikanan tangkap dan merumuskan strategi peningkatan pemanfaatan Pelantar Koperasi Unit Desa Tanjungpinang. Metode pengumpulan data dilakukan dengan pengisian kuesioner melalui wawancara dan studi literatur. Metode analisis data menggunakan analisis deskriptif dan analisis SWOT. Hasil penelitian ini adalah deskripsi kondisi aktual pelantar koperasi unit desa beserta permasalahan yang ada dan rumusan strategi pemanfaatan fasilitas di Koperasi Unit Desa Tanjungpinang sebagai pangkalan pendaratan ikan. Strategi yang dirumuskan dari penelitian ini adalah meningkatkan fasilitas dengan cara pembangunan yang agresif, menambah fasilitas, memperluas distribusi hasil produksi dan menambah ekspor, serta melakukan peningkatan kualitas SDM melalui pelatihan dan pemberdayaan kepada nelayan. Strategi yang dipilih merupakan bagian dari strategi S-O, yang memanfaatkan faktor internal kekuatan dan faktor eksternal peluang., The Tanjungpinang Village Unit Cooperative Fish Landing Site is one of the landing sites for fish caught in Tanjungpinang City. This fish landing site has great potential because of its strategic location, which is close to the island and the market. However, this great potential cannot be appropriately utilized because few fishing boats lean. Its function is not suitable for fish landing but is also used to land passengers between islands and commercial goods. Based on these problems, the purpose of this research was to identify the actual conditions and causes of the Tanjungpinang Village Unit Cooperative Fish Landing Site function that is not following its function as a place for capture fisheries activities and formulate strategies to increase the utilization of the Tanjungpinang Village Unit Cooperative fish landing site. The data collection method has been done by filling out questionnaires through interviews and literature studies. The analysis methods were descriptive analysis and SWOT analysis. The results of this research were a description of the actual conditions of the village unit cooperative fish landing site along with the existing problems and the formulation of strategies for utilizing facilities at the village unit cooperative fish landing site as a fish landing site so that there are several strategies formulated from this research. Firstly, improving facilities by aggressive development, adding fulfilled facilities, expanding the distribution of fish catch production, and adding exports. As well as improving the quality of human resources through training and empowerment to fishers, the chosen strategy was part of the S-O strategy, which utilizes internal strength factors and external opportunity factors.

Judul: Analysis of Fishers Enthusiasm in Utilization of Tanjung Adhikarta Fishing Port, Kulon Progo Regency.
Abstrak: Pelabuhan Perikanan Tanjung Adhikarta (PPTA) di Kabupaten Kulon Progo, Pesisir Daerah Istimewa Yogyakarta (DIY) diproyeksikan menjadi pusat pertumbuhan ekonomi dimana terdapat layanan usaha perikanan tangkap. Namun belum dimanfaatkan secara optimal oleh nelayan dan masyarakat setempat. Penelitian ini bertujuan untuk mengidentifikasi faktor pendorong, penghambat dan animo nelayan dalam melakukan kegiatan perikanan tangkap dengan PPTA sebagai basis. Subjek penelitian ini meliputi nelayan, pegawai pelabuhan dan stakeholder’s lainnya. Secara keseluruhan, ada empat faktor pendorong nelayan dan masyarakat dalam melakukan kegiatan perikanan tangkap, yaitu harga ikan yang relatif stabil, kemudahan masyaakat mendapatkan pelayanan, tidak ada praktek KKN dan tempat pelelangan ikan (TPI) yang beroperasi normal. Empat faktor penghambat nelayan dan masyarakat melakukan kegiatan perikanan tangkap di PPTA adalah pasar ikan yang tidak beroperasi maksimal, suplai bahan baku ikan yang minim, alat peralatan perbengkelan kapal tidak lengkap dan area perbengkelan yang ada tidak dimanfaatkan. Selain itu, kualitas pelayanan pelabuhan menurut para nelayan masih berada di bawah harapan, dengan 4 faktor pelayanan yang harus ditingkatkan, yakni terkait penyediaan bahan baku, stabilitas harga, pemanfaatan bengkel, dan sarana prasarana peralatan bengkel kapal. Nelayan juga merekomendasikan agar keberadaan TPI tetap dipertahankan. Faktor-faktor lainnya dianggap kurang penting namun seyogianya tetap menjadi diwaspadai karena sewaktu-waktu bisa menjadi permasalahan yang tidak terduga., Tanjung Adhikarta Fishing Port (TAFP) in Kulon Progo Regency, a coastal region of Yogyakarta (DIY), is projected to be an economic growth centre where services capture fishery and other business types are located. However, if local fishers and communities have not optimally utilized this facility, it is classified as one wasted development output. This study aims to identify the fishers and local community's driving factors, obstacles, and enthusiasm for using the port. The subjects of this study include fish, port employees, and other stakeholders. On the one hand, four driving factors encourage fishermen to carry out fisheries activities at the port: stable fish prices, ease in services, absence of corruption, collusion and nepotism, and operational fish auction hall. On the other hand, there are four obstacles: the poor operation of the fish market, minimal supply of fish, incomplete equipment in the ship workshop, and an unutilized workshop area. Fishers consider the quality of port services is still below their expectations, and improvement is needed for the supply of fish, fish price stability, utilization of workshops, and infrastructure for ship workshop equipment. Fishers recommend that the existing fish auction is maintained. Other factors are considered less important but be cautious about anticipating an unexpected problem in the future.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
