Abstract

ABSTRACTThe waters of Northern Nias, North Sumatra Province have a great potential for natural resources, one of which is the reef which is often used as a fishing ground. This study aims to identify and monitor the distribution of coral reefs around the waters of Northern Nias. The location of study is limited by coordinates 97° 0'31'' - 97° 16'54'' E and 1° 29'2'' LU - 1° 6'24'' N. The study locations were grouped in 6 (six) areas including Mardika reef, Wunga reef, Mausi1 reef, Mausi2 reef, Tureloto reef and Senau reef. The data used were Sentinel 2A imagery acquisition on 19 September 2018 and field observations made on 6-12 September 2018. Data processing includes geometric correction, radiometric correction, water column correction and classification using pixel-based and object-based methods as well as by delineating on the image. One classification method will be chosen that is most suitable for the location of the reef. The results show Sentinel 2A was very helpful in mapping the distribution of coral reefs compared to direct observation in the field. The use of image classification method rightly is very helpful in distinguishing coral reef objects from surrounding objects. The estimated area of coral reefs was 1,793.20 ha with details of the Mardika reef 143.27 ha, Wunga reef 627.06 ha, Mausi1 reef 299.84 ha, Mausi2 reef 141.873 ha, Tureloto reef 244.73 ha, Senau reef 336.44 ha. The existence of coral reefs have a high potential as a fishing ground and a natural tourist attraction.Keywords: coral reefs, sentinel 2A, lyzenga 1978, image classification, Northern NiasABSTRAKPerairan Nias Utara yang terletak di Provinsi Sumatra Utara memiliki potensi kekayaan alam yang besar dimana salah satunya adalah gosong karang yang sering dijadikan lokasi penangkapan ikan oleh nelayan. Penelitian ini bertujuan untuk mengidentifikasi dan monitoring sebaran gosong karang di sekitar perairan Nias Utara. Lokasi penelitian dibatasi dengan koordinat 97°0’31’’ - 97°16’54’’ BT dan 1°29’2’’LU – 1°6’24’’  LU. Untuk mempermudah dalam pengolahan data maka lokasi kajian dikelompokkan dalam 6 (enam) kawasan diantaranya gosong Mardika, gosong Wunga, gosong Mausi1, gosong Mausi2, gosong Tureloto dan gosong Senau. Data yang digunakan adalah citra satelit Sentinel 2A hasil perekaman tanggal 19 September 2018 dan hasil pengamatan lapangan yang telah dilakukan pada tanggal 6 - 12 September 2018. Pengolahan data meliputi koreksi geometrik, koreksi radiometrik, koreksi kolom air dan klasifikasi menggunakan metode klasifikasi berbasis piksel dan berbasis objek serta deliniasi citra. Dari ketiga metode klasifikasi tersebut akan dipilih satu metode klasifikasi yang sesuai dengan lokasi gosong karang. Hasil penelitian menunjukkan citra Sentinel 2A sangat membantu dalam memetakan sebaran gosong karang dibandingkan dengan pengamatan langsung di lapangan. Pemilihan metode klasifikasi citra satelit yang tepat sangat membantu dalam membedakan objek gosong karang dengan objek di sekitarnya. Estimasi total luasan gosong karang di perairan Nias Utara adalah 1,793.20 ha dengan rincian luasan gosong karang Mardika 143.27 ha, gosong Wunga 627.06 ha, gosong Mausi1 299.84 ha, gosong Mausi2 141.873 ha, gosong Tureloto 244.73 ha, gosong Senau 336.44 ha. Keberadaan gosong karang memiliki potensi yang tinggi sebagai lokasi penangkapan ikan dan memiliki daya tarik sebagai tempat wisata alam.Kata kunci: gosong karang, sentinel 2A, lyzenga 1978, klasifikasi citra, Nias Utara

Abstract

Water is a component in the earth that is very important for human life. The availabilityof water is always wanted to meet a demand of water supply, such as for drinkingwater, washing, taking a bath, and etc. Along with population growth, so the need ofwater will be still increasing, including Tanah Datar. In this paper will be describedconcerning to characteristics, and condition of water in Pacitan Area, East JavaProvince, especially Donorojo district. This location occupies geographically betweenthe latitude of 00o17’ and 00o39’ south and the longitude of 100o19’ and 100o51’ eastBased on survey in field, condition of aquifer in Telaga Banta is located in 20 – 60meter depth, and the result of laboratory points to that the quality of water in thisarea meets the requirement for drinking water.The main uses of ground water include irrigation uses, drinking-water and otherpublic uses, and for supplying domestic water to people who do not receive publicsupply water. The majority of water used for self-supplied domestic and livestockpurposes came from ground-water sources.

Abstract

Air adalah zat transparan yang berupa cairan yang membentuk sungai, danau, laut dan hujan, dan merupakan unsur utama dalam kehidupan manusia. Air selalu menjadi hal penting bagi keberlangsungan hidup manusia dan makhluk organisme lainnya. Air hujan yang sampai ke permukaan tanah tidak berhenti sampai disitu tapi akan mengalir sepanjang permukaan tanah menuju sungai atau danau dan laut. Hujan tersebut sebagian juga tertahan oleh tumbuhan, yang selanjutnya akan diuapkan kembali ke atmosfir. Bagian lainnya masuk ke dalam tanah melalui pori-pori pasir dan batuan, yang kenudian disebut sebagai akuifer. Pergerakan air melalui akuifer ini seperti segelas air yang dituangkan ke dalam gundukan pasir. Para penyedia air membuat sumur melalui tanah dan formasi batuan untuk sampai ke akuifer dan mensuplai air ke masyarakat. Banyak juga perumahan-perumahan yang membuat sumur sendiri untuk keperluannya sehari-hari. Pada tulisan ini akan dibahas mengenai kondisi air tanah dangkal atau sumur pada daerah Wonomarto, Kabupaten Lampung Utara. Berdasarkan hasil kajian dan analisis, pada daerah penelitain dijumpai kedalaman air sumur yang berbeda-beda dan air tersebut dimanfaatkan untuk keperluan sehari-hari.  Keywords : Shallow ground water, Wonomarto.

Abstract

Seasonal characteristics of vegetation, such as growing season are closelyrelated to characteristics of the lower atmosphere, and are thereforeimportant variables in global models and vegetation monitoring. NormalizedDifference Vegetation Index (NDVI) data derived from the National Oceanicand Atmospheric Administration’s (NOAA) Advanced Very High ResolutionRadiometer (AVHRR) satellite sensor offer a means of efficiently andobjectively evaluating vegetation response over large geographic areas.Those vegetation responses were computed based on time-series NDVIdata collected from May 1997 to April 1998 over South East Asia. Measureof growing season was computed and analyzed for land cover type. It isdifficult if not impossible to objectively define an absolute the time of thegrowing season from satellite observations. The purpose of this paper isto determine the threshold of the growing season by using GeographicInformation System (GIS).
