Ethnooceanography and the intersection of shar'i aspects to determination of the early of Ramadan and Shawwal by Joguru Sultanate of Tidore. The determination of the early of the new month of Ramadan and Shawwal was very important for Muslims because it is related to the time of worship. Judge syara 'The Sultanate of Tidore (Joguru) has long applied the method of determining the early month of Hijri (Ramadan and Shawwal) through tidal movement observed on "akebai" included in ethooceanography and called Joguru Method (MJ). Hilal that has never been seen in Tidore and its surrounding areas in the long-term cycle of moon (34 years) caused its early moon to be inapplicable due to non-fulfillment of the requirement of hisab (hadith). MJ makes observation (rukyat) change of tidal movement on "akebai" is "ijtihÄd". The appropriateness of the scientific aspects of ethnoocaenography and the intersection of the shar'i aspects make it a comparative method of determining the beginning of the new month of Hijri in astronomy (hilÄl). Required the expansion of the meaning of the â€œhilÄlâ€ as an indicator of the beginning of the month of the Hijri calendar.[]Ethnooceanography dan titik temu aspek Syarâ€™i dalam penentuan awal bulan Ramadhan dan Syawal oleh Joguru Kesultanan Tidore. Penentuan awal bulan baru Ramadhan dan Syawal sangat penting bagi umat Islam karena berkaitan dengan waktu ibadah. Hakim syaraâ€™ Kesultanan Tidore (Joguru) telah lama mengaplikasikan metode penentuan awal bulan baru Hijriah (Ramadhan dan Syawal) melalui pergerakan pasang surut yang terpantau pada â€œakebaiâ€ termasuk dalam ethooceanography dan disebut dengan Metode Joguru (MJ). Hilal yang tidak pernah terlihat di wilayah Tidore dan sekitarnya selama siklus jangka panjang (34 tahun) menyebabkan hisab awal bulan tidak dapat diaplikasikan akibat tidak terpenuhinya persyaratan hisab (hadis). MJ melakukan pengÂamatan (rukyat) perubahan tinggi air pada â€œakebaiâ€ adalah â€œijtihadâ€. Terdapat keÂsesuaian aspek sains dari ethnoocaenography serta titik temu aspek syarâ€™i yang menjadikan MJ berpotensi sebagai metode utama sekaligus sebagai metode pemÂbanding dari metode umum dalam penentuan awal bulan baru Hijriah. Diperlukan perluasan makna kata â€œhilalâ€ sebagai indikator awal bulan baru penanggalan Hijriah.

Salah satu masalah dalam pemetaan batimetri di perairan gusung terumbu karang adalah sulitnya aksesibilitas kapal survei oleh karena perairannya yang dangkal.Â Di lain pihak, citra satelit sinar tampak telah umum digunakan untuk pemetaan habitat terumbu karang dan kedalaman perairan.Â Studi ini bertujuan menghasilkan peta 3D substrat dasar di gusung terumbu karang dari citra Quickbird.Sejumlah 325 titik sampling menjadi acuan dalam penentuan tipe substrat dasar melalui pendekatan indeks kemiripan Bray Curtis.Setelah koreksi atmosferik, metode koreksi kolom air diaplikasikan pada citra dan ditingkatkan akurasinya dengan kombinasi profil geomorfologi. Pendekatan ini telah menghasilkan peta substrat dasar di gusung Karang Lebar dengan akurasi tematik 82%.Â Sejumlah lebih 5700Â titik perum di regresi dengan kanal hijau dan merah untuk mendapatkan model estimasi batimetri dari citra Quickbird berdasarkan tipe substrat.Â Gabungan model regresi menghasilkan nilai koefisien determinasi=94% dan RMSE=0.4 meter.Â Interpolasi data gabungan citra batimetri pasir dan data perum menghasilkan model 3D batimetri di Karang Lebar dengan ME=0.4 m dan RMSE=0.9 m.Â Hasil ini menunjukkan peta batimetri yang dihasilkan belum dapat memenuhi persyaratan navigasi, meskipun demikian masih dapat digunakan untuk keperluan lainnya seperti pengelolaan sumberdaya, pemodelan oseanografi dan lain-lain.Kata kunci: substrat dasar, Quickbird, batimetriABSTRACTOne of the problems when conducting bathymetric mapping in patch reef environments is shallow water condition.The shallowness complicates the surveillance boat to access the location. Apart from this, using visible satellite imagery, ones still can map coral reefs and shallow water depth. This study goal was to produce 3D bottom substrate map from quickbird imagery.Â About 325 sampling points wereselected to characterize bottom substrate based on the similarity index from Bray Curtis. After theatmospheric correction, a water-column correction method was implemented and then a geomorphologic profilingwas applied to improve the mapâs thematic accuracy. Theapproach has resultedan accuracy 82% for bottom substrate map.Â A bathymetric estimation model then wasbuilt from a regression analysis to 5700 sounding data and combination of green and red channel value of quickbird. The model has 0.4m RMSE value and 94% for itscoefficient determination The fusion of sand bathymetric image and sounding data results on the 3D bathymetric model of Karang Lebar with ME=0.4 m and RMSE=0.9 m.Â This result shows that the produced bathymetric map was not fulfilled the navigation requirement, but still potential as an additional information for resource management, oceanographic modeling etc.Keywords: bottom substrate, Quickbird, bathymetry

Indonesia is situated in the Coral Triangle region that has the worldâs highest coral reef biodiversity. Therefore, coral reef monitoring needs to be conducted regularly to assess the condition of coral reef ecosystem for management purpose. There are several coral reef monitoring methods available such as the line intercept transect (LIT), point intercept transect (PIT), photo transect, belt transect and benthic towed-diver. In Indonesia, LIT and PIT are the most commonly used methods for coral monitoring. However, there is a main disadvantage when collecting data using these methods, that is scientific divers need to spend hours to input the data after dives. Here, we introduce an electronic logging instrument called Coral Input Data Instrument that helps to decrease the input data time by employing a look-up table system that simplifies data input process by replacing text with numerical coding. In addition, water quality data such as temperature, depth and visibility also are embedded in the electronic logging instrument. The instrument hardware consists of Arduino Mega 2560, keypad 4x3, LCD Module 16x2 character, real time clock, temperature sensor, pressure sensor, visibility sensor and micro SD card module. Arduino IDE 1.6.5 software is used to program the microcontroller. In this paper, we describe the design and implementation of the instrument in the field.

Seagrass is one of productive and economical marine ecosystem, but recently there are indications that this area is decreasing and every kind of damage is happening. The research was conducted to reveal the change of seagrass width area and to determine the suitable location for donor and acceptor of seagrass transplantation. Methods of research were collecting and analyzing the satellite image of the research location, bathymetri mapping and water quality parameter, and also determining environment charasteristics that suitable to be performed by counting Seagrass Transplantation Suitability Index (STSI). The results show that in year 1999-2004, the derivation area of seagrass was 678.300 m2. Pari island has depth range between 0-50 metres and the physics and chemical parameter of water have a good range where the seagrass can live. According to the analysis result of STSI, suitable areas for seagrass transplantation donor is station no. 5 and 6 for seagrass species of Enhalus acoroides and station no. 2 and 7 for seagrass species Thalassia hemprichii. The implication of this research is that the seagrass needs rehabilitation to overcome seagrass ecosystem for better condition.
