Abstract

CADS_TOOL is a software decision support tool for floating net cages management which constructs of two elemens, software and technic module. It has been developed by the copyright holders (the Australian Centre of International Agriculture Research ( ACIAR ), the Australian Institute of Marine Science ( AIMS ) and the Departemen Kelautan dan Perikanan ( DKP : Ministry of Marine Affairs and Fisheries, Indonesia)as a tool. The objective of this software is to classify a site, to select the best site from several site alternatives, to calculate the sustainable holding density of a chosen site and to perform a basic economic appraisal of a farm at that site. CADS_TOOL includes 4 models for calculating holding or carrying capacity as sub-tabs under the Holding Capacity tab. For marine cages, the methods used are: Simplified MOM based on Stigebrandt et al., (2004), Tookwinas et al. (2004) and Hanafi et al. (2006), while Pulats et al. (2003) is used for freshwater cages in lakes/dams. In this paper will describe only a Tookwinas model.

Abstract

The morphoedaphic index (MEI) has been used globally as a fish-yield estimator with widely divergent results. The fandamental concept of the MEI embraces standard thermodynamic theory, that of matter ( natrients) transported by energy within an open system. Of the three morphometric factors considered mean depth ,volume and area. The MEI is a reasonable compromise between unmanageable complexity and ecologic over simplification. Even so, its appropriate application presupposes both a fisheries and a limnological expertise, a rare disciplinary combination in those workers who might derive the greatest benefits from its use.In this paper, study on the determining of water productivity in artivicial lakes with morphoedaphic index analysis was showed.

Abstract

Research aimed to learn and know the bottom intrusion mechanism in Hurun Bay Lampung. Three kinds surveys were conducted consist of mooring survey, synoptic oceanographic survey and 25 hour survey. The monitoring data of water temperature indicated that at Hurun Bay occurred bottom intrusion from middle February until early July. The mass water was colder, more saline and contained less DO than the overlaying water. These phenomena may be caused by eastern monsoon from Java Sea to Lampung Bay and Hurun Bay. Vertical profile distribution showed that there are significant different in temperature, salinity and DO between surface and bottom layer. Along bottom deeper than 22m were identified as a termocline layer which was colder and more saline and contained less DO. Result of 25 hour survey resumed that the lowest DO in this water mass appeared in early July and it propagated from offshore to the coast with velocity 0.07 m/s. This condition will be a treatment for marine cultivation stakeholder in this area.Key words : Bottom Intrusion, Hypoxia

Abstract

Rumah tangga merupakan sektor penghasil sampah paling besar dimana komposisi yang paling dominan adalah sampah makanan. Salah satu alternatif pengolahan sampah makanan adalah dengan mengkonversi bahan organik tersebut menjadi produk bernilai guna tinggi, yakni pupuk organik. Metode yang dipakai dalam kegiatan pengabdian ini adalah pemberian pelatihan kepada kader Pemberdayaan & Kesejahteraan Keluarga dan Kelompok Wanita Tani Kampung Bumi Mas untuk mengolah sampah organik menjadi pupuk cair dan pupuk padat untuk digunakan kembali sebagai nutrisi alami untuk tanaman. Target khusus yang ingin dicapai adalah untuk melakukan transfer teknologi aplikatif dengan menggunakan alat dekomposter sederhana skala rumah tangga kepada masyarakat. Selain itu juga mengajak masyarakat untuk turut aktif dalam upaya penurunan emisi gas rumah kaca yang dihasilkan dari sampah organik rumah tangga.

Abstract

Serayu River has decrease in capacity, both in quality and quantity. This condition causes the function and performance of the river as a source of water for community activities to be less than optimal. Efforts to improve monitoring of the Serayu River water quality require a continuous monitoring program implemented online. Therefore, a more reliable effort to control water pollution is needed in order to maintain water quality according to its purpose. The purpose of the research is to periodically monitor water quality and determine the status of water quality in the Serayu River. It is hoped that this explanation will be used as a comparison for manual monitoring activities that have been did in the Serayu River previously and as a reference for monitoring water quality in other locations. The method of measuring water quality is using online monitoring system and determining the status of water quality using the Storet analysis method. Samples were taken and measured from 2 stations namely Bendung Wanganaji and Bendung Gerak Serayu using mulptiprobe sensors consisting of parameters of temperature, DO, pH, TDS, conductivity, turbidity, nitrate and ammonia. Data from sensor measurements are sent and analyzed online by the onlimo system. The data that has been analyzed are then verified and reanalyzed using the Storet method. The results of the analysis of water quality monitoring of Serayu River state that the quality in Serayu River water is classified as light to moderate polluted. ABSTRAK Sungai Serayu telah mengalami penurunan kapasitas, baik secara kualitas maupun kuantitas. Kondisi ini menyebabkan fungsi dan kinerja sungai sebagai sumber air bagi aktivitas masyarakat menjadi kurang optimal. Upaya meningkatkan pemantauan kualitas air Sungai Serayu memerlukan program pemantauan yang kontinyu dan dilaksanakan secara online. Oleh karena itu diperlukan upaya pengendalian pencemaran air yang lebih handal dalam rangka untuk menjaga kualitas air sesuai dengan peruntukannya. Tujuan penelitian yaitu untuk memantau kualitas air secara berkala dan menentukan status mutu air di Sungai Serayu. Paparan ini diharapkan menjadi bahan komparasi kegiatan pemantauan manual yang telah dilakukan di Sungai Serayu sebelumnya dan menjadi acuan pemantauan kualitas air di lokasi lain. Metode pengukuran kualitas air menggunakan sistem online monitoring dan penentuan status mutu air menggunakan metode analisis Storet. Sampel diperoleh dari 2 stasiun yaitu Bendung Wanganaji dan Bendung Gerak Serayu menggunakan mulptiprobe sensor yang terdiri dari suhu, DO, pH, TDS, DHL, turbiditas, nitrat dan amonia. Data hasil pengukuran sensor dikirim dan dianalisis secara online oleh sistem onlimo. Data hasil analisis selanjutnya diverifikasi dan dianalisis ulang menggunakan metode Storet. Hasil analisis pemantauan kualitas air Sungai serayu menyatakan kualitas air Sungai Serayu tergolong dalam klasifikasi tercemar ringan hingga tercemar sedang. Kata Kunci: Sungai Serayu, status mutu air, Storet, Onlimo, pemantauan online
