Berkaitan dengan hal itu, perubahan penggunaanlahan terus terjadi dan dikhawatirkan tidak mendukung keberlanjutan lingkungan.Tujuan dari penelitian ini adalah menganalisis bagaimana perubahan penggunaan lahankota Pelabuhanratu sampai dengan tahun 2032. Metode yang digunakan dalampenelitian ini adalah Cellular Automata-Markov dengan beberapa faktor yangmendorong terjadinya perubahan penggunaan. Faktor penentu dibuat dengan logikafuzzy dengan beberapa variabel yaitu jarak dari jalan, jarak dari point of interest, jarakdari sungai, jarak dari pantai, wilayah ketinggian, kemiringan dan tutupan lahan. Dataini digunakan sebagai masukan pada Cellular Automata-Markov Chain. Tutupan lahandiambil dari google earth pada tahun 2002, 2010 dan 2017. Hasil prediksi menunjukkanbahwa perubahan tutupan lahan sangat signifikan. Nilai akurasi kappa pada modelmencapai 91. Lahan terbangun berkembang linear pada bagian selatan, menyebarpada bagian utara dan beraglomerasi pada bagian barat. ......Pelabuhanratu is a strategic coastal area that matter the local government makePelabuhanratu as a Growth Center of Sukabumi Regency. In this regard, landcoverchanges continue to occur and are feared not to support environmental sustainabilitycaused of growing center. The purpose of this study is to analyze how land use changeof Pelabuhanratu city until 2032. The method used in this research is CellularAutomata Markov in with several factors that encourage the land cover change. Drivingfactor made with fuzzy logic with some variables that is distance from road, distancefrom river, distance from coastline, distance from point of interest, elevation, slope andlandcover. This data is used to create suitability area for built up area as input forCellular Automata Markov tools. Land cover was obtained from google earth in 2002, 2010 and 2017 as the basis of model calculation. The prediction result shows that landuse change in Pelabuhanratu city is very significant with the Kappa Standard level ofaccuracy 91. Built up area has extended from the previous condition that coming fromagricultural area. Built up area growth with linear pattern at south area, spread pattern atnorth area and crowded at west area."

The concept of landscape is known to be always changing dynamically because of its attachment to natural and human activities that continue to grow over time. The purpose of this study is to identify landscape changes from 2010 to 2018 which are associated with natural disaster events. Coastal area is the study target on landscape changes due to natural disasters. The research took place in Pelabuhanratu District, Sukabumi Regency which is known for its varied geomorphological form and its natural disaster events occurance including coastal floods, flash floods, and landslides. The research data was proccessed using ArcGIS 10.4.1 and ENVI 5.1 softwares. Data verification was done by field surveys in the study area. The method of this study is an overlay analysis and explained in the term of spatial dan descriptive concept. The landscape of Pelabuhanratu District is dominated by volcanic landforms and vegetation cover. The total area experiencing landscape changes due to natural disasters is 4.08 km2 of the disrtict area of 91.90 km2 and major changes are involving alteration of land cover area."

"[Ikan layur merupakan salah satu komoditas penting dalam perikanan tangkap di Palabuhanratu. Penelitian ini bertujuan menentukan populasi dan potensi ikan layur. Metode yang digunakan ialah data surplus produksi. Data ikan dibutuhkan untuk menggambarkan dinamika suatu populasi ikan yang dipengaruhi oleh pertumbuhan, mortalitas, dan migrasi ikan. Dinamika populasi dianalisis dengan paket perangkat lunak FISAT II dan pengkajian potensi lestari dianalisis denganmodel surplus produksi MSY. Hasil pengamatan Agustus-September 2014 menunjukkan perubahan kisaran panjang ikan dari kisaran 44,00?96,80 cm menjadi 47,00?97,99 cm dan berat rata-rata ikan berubah dari 285,33 gram menjadi 309,00gram. Perubahan panjang ikan ini karena ikan mengalami proses pemijahan. Hasil estimasi pada waktu pengamatan memperlihatkan bahwa laju eksploitasi populasi ikan layur belum mencapai tangkap lebih (overfishing) dengan nilai batas tingkat penangkapan dibawah optimum 0,50. Dalam rangka mewujudkan perikanan layur berkelanjutan, disarankan menetapkan musim penangkapan, penambahan upaya dan wilayah tangkapan, serta pendataan berbasis spesies.......Hairtail is one of the important fish catches in Palabuhanratu waters. Thisstudy aims to determine the populations and potential of hairtail. To achieve theseobjectives, it required accuracy and precision data. Data of fish are needed to describethe dynamics of a fish population which influenced by fish growth, mortality, andmigration. The population dynamics is analyzed with FISAT II software package and potential sustainable surplus production is analyzed with MSY production surplus model. The observation result from August to September 2014 showed that fish length range has changed from 44.00-96.8 cm to 47.00-97.99 cm. In similar period, the average weight also changed from 285.33 gram to 309.00 gram. The length changes are apparently due to the process of spawning. Based on the observation, the estimation result shows that the speed of exploitation of hairtail population is yet to reach overfishing fisheries, suggested to fix the fishing season, adding the efforts and fishing zone, also data collection based on species.
