Abstract

Abstract. A meteorological prespective to analyze the Thunderstorm forecasting in Jakarta has been done. The principal indices to be adapted in a fishpond were also arranged in the study. Storms in Jakarta, so-called as Ordinary Cell Thunderstorms, are frequently arose in the afternoon, particularly during transition period on March-May and September-November in which many of them are triggered by different in surface heating. The latter emerged to an atmospheric instability and force the air parcel to rise through the atmosphere. RAOB was employed to the forecasting of Thunderstorm. A number of such indices as K and Showalter indices as well as CAPE are produced and applied to forecast the conditional instability of the troposphere. The result showed that the extension of inversion layer in ~500–300 hPa implied the shrink of humidity and might strength the convective instability. In addition, the higher amount of CAPE proved the maximum velocity of updraft which lead to a strong convection and vertical wind shear during Thunderstorm in Jakarta. On the other hand, based on the storm indices, three principal indices adapted in a fishpond were also arranged i.e. normal, moderate and risk condition.Keywords.

Abstract

Shipbuilding is one of the marine industries which in development needs to pay attention to various parameters from the sea and land. This research was conducted in March to May 2022 with the aim of identifying the influence of oceanographic factors and water quality on the development of the shipbuilding industry at the fishing port of Sabang City. The oceanographic data used includes tides, wind, bathymetry, and sediment composition observed at 12 station points. The depth and tide data are then processed using QGIS. Wind data was analyzed using the Wind Rose Plot and sediment using the Wentworth scale. Oceanographic factors in Sabang Bay have shown very satisfactory results for the development of fish landing bases. The wind in the waters of Sabang Bay blows northwest with high speeds ranging from 10.00 m/s. The depth of the waters indicates a potential location for ship mooring. Sandy sediment is the most common type of sediment found. The tides that occur in the bay of Sabang are relatively stable. Oceanographic factors in Sabang Bay have shown very satisfactory results for the development of fish landing bases.Keywords:OceanographyShipyardSabang Bay

Abstract

The waters of the Mamberamo watershed are around 7.7 million hectares. Some territorial waters are surrounded by jungles that are rich in unique biodiversity. Diverse biodiversity must be accompanied by a state of good water quality. So that the monitoring of water quality is very good in terms of physical and chemical physics parameters. Monitoring using chemical physics parameters has been widely used, but using aquatic biota is still rare, so it is expected to be more assertive in exposing the state of river damage. Aquatic biota used is periphyton. Periphyton has the potential to be a study of ecological indicators, a major producer in the food chain and its inherent nature in aquatic substrates. The purpose of this study was to determine the diversity of the periphyton community, determine the quality of waters in terms of chemical physics in the Mamberamo watershed and see the relationship between the two parameters. The method of determining the location was purposive sampling with descriptive analysis of the correlation results. Field observations and sampling were carried out on three tributaries and ponds in the form of flood-exposed lakes in the Membramo watershed in February, May, August and October 2016. The results showed the highest periphyton composition of Bacillariophyceae class followed by Chlorophyceae and Cyanophyceae. The diversity value of the Mamberamo river is 1 H '= 3 which indicates moderate diversity, and the dominance index value ranges from 0.15 to 0.45, which indicates that there is no species that dominates in the waters of the Mamberamo River. Based on the results of the water quality assessment in the presence of periphyton and the physical chemistry characteristics of the water, it is found that the criteria for river water quality are classified as good and not polluted.Keywords:Ecological indicatorsChemical physics characteristicsPeriphytonMamberamo RiverPapuaABSTRAKLuas perairan DAS Mamberamo berkisar 7,7 juta hektar. Sebagian wilayah perairan dikeliling oleh hutan rimba yang kaya akan keanekaragaman hayati yang unik. Keanekaragaman hayati yang beragam harus disertai keadaan kualitas air yang baik. Sehingga pemantauan kualitas perairan sangat perlu baik ditinjau dari parameter fisika kimia dan biologi. Pemantauan menggunakan parameter fisika kimia telah banyak digunakan, tetapi menggunakan biota perairan masih jarang ,sehingga diharapkan dapat lebih tegas dalam mengekspresikan keadaan kerusakan sungai. Biota perairan yang digunakan dalam penelitian ini adalah perifiton. Perifiton berpotensi sebagai kajian indikator ekologis, produsen utama dalam rantai makanan serta sifatnya yang menempel di substrat perairan. Tujuan penelitian ini adalah untuk mengetahui keragaman komunitas perifiton, mengetahui kualitas perairan dari segi fisika kimia di DAS Mamberamo serta melihat hubungan antara kedua parameter tersebut. Metode penentuan lokasi purposive sampling dengan analisis deskripitif dari hasil korelasi. Pengamatan lapangan dan pengambilan sampel dilakukan pada tiga aliran anak sungai dan telaga yang berupa danau paparan banjir di DAS Membramo pada Februari, Mei, Agustus dan Oktober 2016. Hasil penelitian menunjukkan komposisi perifiton tertinggi kelas Bacillariophyceae diikuti Chlorophyceae dan Cyanophyceae. Nilai keanekaragaman sungai Mamberamo adalah 1H’=3 yang menyatakan keanekaragaman sedang, dan nilai indeks dominasi berkisar 0,15-0,45 yang menandakan bahwa tidak ada jenis yang mendominasi di perairan Sungai Mamberamo. Berdasarkan hasil penilaian kualitas air secara keberadaan perifiton dan karakteristik fisika kimia air maka didapat kriteria kualitas perairan sungai yang tergolong bagus dan belum tercemar.Kata kunci:Indikator ekologisKarakteristik fisika kimiaPerifitonSungai MamberamoPapua

Abstract

Oyster shell can be used as alternative calcium source. Utilizing of oyster shell into nano calcium flour can be used to decrease solid waste. The usage of nano calcium flour in feed is important applied as calcium supplements with cherax quadricarinatus. The purpose of this research is to study the effect of nano calcium addition on feeds to increase moulting frequency, survival and growth rate of freshwater lobster. This research has been done during 60 days in fisheries Laboratory, Abulyatama University. Two percents nano calcium addition on feeds gives significant effect on growth rate and very significant effect to moulting frequency of freshwater lobster. Which has moulting frequency 2.71. Where the treatment was not added nano calcium has moulted frequency 1.29. But, nano calcium addition on foods did not affect survival rate.Cangkang tiram dapat digunakan sebagai alternatif sumber kalsium. Pemanfaatan cangkang tiram menjadi serbuk nanokalsium dapat mengurangi limbah padat. Penggunaan serbuk nanokalsium pada pakan penting dilakukan sebagai suplemen kalsium untuk lobster air tawar. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan nanokalsium pada pakan terhadap pertumbuhan, frekuensi molting dan kelangsungan hidup Lobster Air Tawar (LAT). Penelitian ini dilakukan selama 60 hari di laboratorium perikanan, Universitas Abulyatama. Data dianalisa menggunakan uji T (perbandingan) antara lobster yang diberi pakan nanokalsium dan tanpa penambahan nanokalsium. Nanokalsium yang ditambahkan ke dalam pakan sebanyak 2% berpengaruh nyata terhadap pertumbuhan lobster air tawar (thitung ttabel), dan berpengaruh sangat nyata terhadap jumlah molting dengan frekuensi molting 2,71 kali/ekor terhadap lobster yang diberi pakan nano CaO, sedangkan yang diberi pakan komersil hanya 1,29 kali/ekor. Namun, tidak berpengaruh terhadap tingkat kelangsungan hidup (thitung ttabel).

Abstract. The oysters (Ostreidae) isone of economically important bivalves for urban community in Kuala Gigieng, Aceh Besar District. Presently, the quality and quantity of oyster is decreased over the years by intensive exploitation and water pollution. Therefore, theobjective of the present study was to analyze population structure and habitat condition of oystersin estuary area of Kuala Gigieng, Aceh Besar District, Aceh Province. The sampling was conducted at three locations during August to September 2013. The sampling locations were determined based on anthropogenic activities. A total of two genus of oysters were recorded during the study i.e Crossastrea with four species (C. gigas, C. iridescens, C. angulata, C. virginica) and and Ostrea edulis with one species (O. edulis). The highest density (39 ind m-2)of oysters were found at undisturbed and less pressure environment. The distribution pattern of Ostreidae in the Kuala Gigieng water was clustered where frequency of occurrence wasin small class size of 24 mm to 37.20 mm with optimum harvested of 32.27 mm. The growth of the oysters was relatively slow as shown by the maximum length (Lmaks) that can only reach 37.91-72.81 mm within 0 to 3.42 years. Generally, oysters population structure and habitat conditions in Kuala Gigieng Water was declined over the yeras. Therefore, it is a crucially needed to plan a management strategy for oysters with regulation on fishing, shellfish farming and waste disposal regulation to ensure the oysters population remains sustain.Keywords : Environment factors; fishing, growth; Kuala Gigieng; Oyster; population structureAbstrak.

Abstract

Fishery management is an activity that must be carried out to achieve sustainable fisheries. Fisheries management using the Ecosystem Approach to Fisheries Management (EAFM) approach is the sustainable use of fishery resources and protection of fish stocks in nature. One of the objectives of fisheries management in social and economic aspects is how fisheries can ensure the socio-economic welfare of the fishing community. Using fishing gear that is not environmentally friendly is one of the triggers for social conflict between fishermen and the uncertain selling price when the peak season of fish impacted the fishermen's economy. Therefore, the purpose of this research is to examine the socio-economic domain indicators from the aspect of EAFM-based coastal and marine resource ecosystem management. This research was conducted from January to February 2021, located in Simeulue District, Sub-District East Simeulue. The data collection method used in the study was interviews and field surveys. The determination of respondents is done by using a gradual sampling technique or stratified random sampling. Data analysis uses an ordinal-based Likert score of 1,2,3 for each indicator, namely the economic domain, fishery household income (RTP), savings ratio, asset ownership, and the social domain, namely stakeholder participation fisheries conflict and the use of local knowledge in fish resource management. Management status in East Simeulue District assessed the aggregate value of the economic domain in the medium category with a score of 48.3. Fishermen still earn less than the minimum wage, while in the social domain, it is in the excellent category with a score of 100 because fishermen, institutions, and related agencies work with each other.Keywords:EAFMEcosystem approachFishery management

Abstract

The high level of public consumption, balanced with the increasingly dense population globally, makes food waste more and more. Food waste is the second-largest contributor to waste in the world. Moreover, the lack of food waste management makes this condition even worse. This food waste can be found, one of which is in restaurants, school canteens, food courts, and others. Fermentation is the process of breaking down complex substances into simpler ones. A fermentation process can help process food waste into various products such as liquid organic fertilizer, compost, biogas, and raw material for fish feed. Through the fermentation process, food waste can be used as an alternative fish feed with high nutritional content to benefit fish cultivators. Fish need many nutrients for their bodies, with food waste that has been processed will meet the dietary needs of fish. The cultivators will benefit more from the cost of feed and the sale of fish that can meet consumer needs.Moreover, the demand for the fish market is increasing every year. Several factors play a role in the success of the food waste fermentation process and the quality of the resulting product to be converted into fish feed raw materials. These factors include incubation time, pH acidity, and microbial factors that can accelerate the spoilage of fish feed raw materials.Keywords:Fermentation,Restaurant wasteFish feedFactorsQuality of feed IngredientsLiterature review on fermentation factors of restaurant organic waste affecting feed quality
