Seaweed has a high economic value in terms of its considerable use in various industries of sweets, cosmetics, ice cream, flavourings, bakery, sauce, silk, meat/fishery canning, medicine and iron-rod welding. In 2005, Indonesia has declared that seaweed as one of the leading commodities to be prioritized and revitalized. To produce quality of industrial-scale seaweed has necessary a serious handling, start from harvesting process, uploading, washing, drying, up to manufacturing caraggenan.This study has tried to produce a seaweed washing machine that capable to improve the quality of the seaweed in the washing process. This washing machine is based on hybrid technology that can be operated using energy from pedal-powered and electrical-powered generated from solar panels.The washing machine resemble three-wheeled transport vehicle using pedal-powered for mobility. Activity of seaweed washing process using plastic drum that rotated. There are two different size of plastic drum used in washing machine, the bigger size for static water storage containers and the little one for dynamic (rotation) using pedal-powered or electrical motor.The rolled chain transmission that connected with integrated toothed gear is used to ratate a dynamic drum. The different between pedal-powered and electrical-motor powered lies in process to rotated dynamic drum. Pedal-powered use manpower to rotated dynamic drum but electrical motor powered from electrical that generated from solar panel. Washing machine with pedal-powered similar like pedal powered that contained in bicycle. Solar panel systems which is the source energy for generated electrical motor consists of solar panel itself, controller, battery and DC to AC converter. Overall the machine has works well butt need improvement in terms of manueverability.

Penggunaan drifter untuk penelitian di bidang oseanografi telah cukup lama dilakukan, namun perancangan, dan pengembangan dari instrumen ini masih terus dilakukan. Rancangan yang murah, ringan dan stabil merupakan beberapa syarat yang dituju oleh para perancang drifter. Di Indonesia penggunaan drifter sebagai alat penelitian oseanografi masih jarang dilakukan dan drifter yang dilepas oleh ARGOS pun hampir tidak ada yang memasuki perairan Indonesia, sehingga penelitian dan analisis data berbasis data drifter inipun masih jarang dilakukan di Indonesia. Ohlman, (2007) mengembangkan drifter yang dirancang untuk perairan pesisir. Beberapa syarat yang ditemukan yaitu drifter pesisir harus memiliki resolusi spasial beberapa meter dan sampel posisi dilakukan setiap beberapa menit. Pengukuran near-real-time data telemetri diperlukan sehingga drifter dapat dilacak dan dipulihkan. Dalam makalah ini diuraikan hasil desain dan konstruksi sistem drifter, serta hasil ujicoba lapang. Diharapkan dari data pengamatan drifter dapat dikembangkan lebih lanjut drifter yang handal dan berkualitas.

The use of Multibeam echosounder (MBES) equipment for seabed detection has been done by several researchers, which provided intensity values of each research object. However, artificial targets (such as shipwreck) was very dangerous object for ship navigation hence its very important to quantify it. This research was conducted in the Sunda Strait to detect the target of metal shipwreck. The Kongsberg EM 2040 MBES was used along with supporting equipment and SIS software as a data recorder. MBES acquisition results then processed using software CARIS. Display of the results were presented using the software CARIS and Surfer. The results of this study showed that the detection of the shipwreck with MBES Kongsberg EM 2040 is very clear with 3-dimensional shape of the shipwreck. The shipwreck backscattering intensity values have range from -3 to +6.99 dB.

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 "ijtihād". 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 (hilāl). Required the expansion of the meaning of the “hilāl” as an indicator of the beginning of the month of the Hijri calendar.[]Ethnooceanography dan titik temu aspek Syar’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 syara’ Kesultanan Tidore (Joguru) telah lama mengaplikasikan metode penentuan awal bulan baru Hijriah (Ramadhan dan Syawal) melalui pergerakan pasang surut yang terpantau pada “akebai” 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 pengamatan (rukyat) perubahan tinggi air pada “akebai” adalah “ijtihad”. Terdapat kesesuaian aspek sains dari ethnoocaenography serta titik temu aspek syar’i yang menjadikan MJ berpotensi sebagai metode utama sekaligus sebagai metode pembanding dari metode umum dalam penentuan awal bulan baru Hijriah. Diperlukan perluasan makna kata “hilal” sebagai indikator awal bulan baru penanggalan Hijriah.

The Sama ethnic group (Bajo) is well known as “Indonesian marine people” that dominantly spreaded in coastal region of eastern Indonesian region. Their activities have been adapting with the territorial water as shown in the determination of their home floor height to prevent from the tidal flood. The purpose of this study was to examine the accuracy of the tidal range calculation by local knowledge of the Sama ethnic group (Sama Ethnic Method, SEM). The analysis was done by comparing tidal range result calculated by the Sama Ethnic Method (SEM) with the standardized tidal harmonic constituents. The result showed that the 2nd tidal peaks (DLB-s) in the 15th “Sya’ban” date was the best date to do measurement of a tidal range. In this case, the “Likkas Silapas” (LS) value at the above date was above the mean height water level (MHWL). Meanwhile, in other dates, the LS value was under MHWL value. The result also showed a strong correlation (R2> 90%) between rasio of tidal high on 1st and 2ndpeaks (DLB-s/DLB-m) on 15th Sya’ban date and LS-s value. The local knowledge of the Sama Ethnic Method to determine the tidal range was effective and scientifically proven. Keywords: the Sama Ethnic group, tidal range, Likkas Boe, Likkas Silapas, Sya’ban

The availability of data in real time and continuous is important to monitor in environmental change as early as possible. Wireless sensor networks (WSN) offer a new paradigm in the field of oceanography that can measure the parameters of complex marine environment using a moored buoy. This paper described design of a data transmission system with a moored buoy and tested the performance of WSN instrument based on ZigBee protocol radio module for monitoring coastal water environment in real time. Instruments were divided into two i.e., (1) five sensors served to measure sea surface temperature, stored the data, and transmitted the data to the base station, and (2) a coordinating instrument that placed on the bases station served to receive and record all measurement results of each sensor. The testing was done by deploying the instrument sensors in waters with depths of 2 to 5 meters and a coordinating instrument was located on the ground as a base station. Each instrument's sensor measure sea surface temperature, store, and transmit it to other nearby sensors and forward data to the next sensor and then to the next sensor send it to the base station. The Packet Delivery Ratio (PDR) value wa used as an indicator to determine the instrument performance and the values were from 89.69% up to 100% with transmission range up to 430 meter and battery endurance was up to 26 hours. The result showed that a buoy moored instrument based on WSN ZigBee radio module protocol has the potential for monitoring coastal water environment in a real time.

Fish Aggregating Devices (FADs) is generally made from foliage like a leaf of coconut, palm and nut, but with the development of marine and fishing technology, the FADs could be made electronic ally. Electronic FADs had been developed by using light and sound as an attractor, and was able to aggregate fish but the catch harvest was still relatively low compared with lift net lamp. In this paper we describe the recent development of electronic FADs. The new electronic FADs has 120 watts total power of LEDs as attractor, 12V 12Ah battery as the energy resources, and HDPE as the body of FADs. The lighting of the new is either blue – red light color (RE1) or red-white light color (RE2). The two kinds of lighting are tested and compared and its light distribution underwater case measured in term of the value of luminous flux. The results showed that new FADs work well in the water with light penetration of RE1 was better than RE2. Keywords: FADs, instrument, fishing, light

Underwater Positioning System (UPS) is a system to track the existence of the position of an object by utilizing the arrival time of the signal measurement. On land, the system uses an electromagnetic signal called GPS. However, because it cannot penetrate water effectively, an acoustic signal is used as an alternative. The purpose of this research is to engineer the control system of data acquisition and underwater acoustic device to measure arrival time (TOA) and apply equation model for underwater sound source positioning system. the effective frequency resonance of the transducer and the hydrophone is at a frequency of 6 kHz. The acquisition control device is able to measure the TOA signal with an error on a digital channel smaller than an analog channel. The difference between the TOA values measured by oscilloscope and acquisition control system is caused by inaccuracy of threshold estimates at the receiver's peak detector circuit. The position of the sound source coordinates obtained from the equation model shows the highest difference in depth point (z) compared to points (x) and (y), caused by the equation model used is limited to four hydrophone units forming a horizontal baseline.
