Semarang is one of many cities which has high vulnerability, damage, and high risk affected by climate change. This study was aimed to determine securing, protecting of Semarang coastal area, especially in Tugu and Genuk Sub-district. Literature review was carried out to seek the proper seawall design and material which feasible to be built in coastal area of Tugu and Genuk Sub-district. Field observation was conducted to determine location characteristic to build seawall in Tugu and Genuk Sub-district. The study revealed that many area of Semarang coast was damage as impact of coastal building, the loss of natural protection as well as effect of global warming. The existing seawall was varied but mostly in damage condition. Therefore it is recommend to build seawall in Karanganyar and Tugurejo Village (in Tugu subdistrict) to support the eco-edutourism in Semarang City as well as ini Trimulyo Village (Genuk Subdistrict) to established sediment enrichment ready for mangroves replant. Semarang merupakan salah satu kota yang memiliki tingkat kerentanan, bahaya dan resiko tinggi akibat dampak perubahan iklim. Kajian ini bertujuan untuk melakukan kajian pengamanan dan perlindungan pantai di wilayah pesisir Kecamatan Tugu dan Genuk, Kota Semarang. Kajian dilakukan ini melalui review literatur dan observasi lapangan. Kajian literatur dilakukan terhadap desain alat penahan ombak (APO) yang memungkinkan dibangun di wilayah pesisir Kecamatan Genuk dan Tugu serta untuk mendapatkan informasi tentang bahan atau material yang dapat digunakan untuk membangun APO. Observasi lapangan dilakukan untuk mengetahui karakteristik lokasi yang akan dibangun APO dan ketersediaan material sesuai desain yang telah direkomendasikan. Hasil kajian ini menunjukkan bahwa kerusakan pantai yang terjadi di Kota Semarang cukup banyak yang diindikasikan sebagai dampak dari bangunan-bangunan yang menjorok ke laut, hilangnya perlindungan alam pantai dan juga merupakan efek dari pemanasan global. Kondisi APO dan breakwater saat ini sangat beragam, namun pada umumnya sudah rusak sehingga mengurangi fungsinya sebagai alat perlindungan pantai. Untuk itu disarankan dibangunnya alat penahan ombak di Kelurahan Karanganyar dan Tugurejo (Kecamatan Tugu) untuk mendukung program eco-eduwisata Kota Semarang dan Kelurahan Trimulyo (kecamatan Genuk) untuk sediment enrichment yang nantinya lokasi siap ditanami mangrove.

Artificial Patch Reef (APR) have been applied as a new method for Biodiversity Conservation Program at Panjang Island, Jepara since 2015. Previous study suggested that design and location of artificial reefs installation affected to abundance of reef fishes, associated with the artificial reef. This study aims to investigated community structure of reef fishes associated to artificial patch reef comparing to reef fishes in nearby natural reefs. Assessment of coral reef condition on two habitats were conducted on July 2019, after 4 years deployment. The results show that artificial patch reefs with a percentage of live coral cover are less than half of natural coral reefs, and have succeeded in increasing the abundance of reef fish with nearly the same density and community structure resembling reef fish in natural coral reefs. The similarity in community structure of the two habitats is probably due to the similarity in habitat type and morphology of the hard corals. The results indicate that Artificial Patch Reef (APR) reefs have increased the coral cover of Acropora branching and resulted in increased reef fish abundance which is compatible with reef fish communities associated with natural coral reefs around it. Aplikasi metode baru terumbu buatan Artificial patch Reef (APR) pada Program Konservasi Bioiversitas Pulau Panjang, Jepara telah dilakukan sejak 2015. Hasil studi menunjukkan bahwa pemilihan desain dan lokasi pemasangan terumbu buatan yang tepat akan meningkatkan kelimpahan ikan karang. Tujuan penelitian ini adalah untuk mengetahui keberhasilan penerapan terumbu buatan APR melalui kelimpahan ikan karang yang berasosiasi pada terumbu buatan dan terumbu karang alami di sekitarnya. Penilaian kondisi terumbu karang tersebut telah dilakukan pada Juli 2019 setelah 4 (empat) tahun pemasangan terumbu buatan. Hasil studi menunjukkan bahwa terumbu buatan dengan persentase tutupan karang hidup lebih kecil, separuhnya dari tutupan pada terumbu karang alami telah berhasil meningkatkan kelimpahan ikan karang dengan densitas hampir sama dan struktur komunitasnya menyerupai ikan karang yang berasosiasi dengan terumbu karang alami. Kesamaan struktur komunitas kedua habitat kemungkinan akibat kesamaan tipe habitat dan morfologi karang keras penyusunya. Hasil ini mengindikasikan bahwa terumbu buatan Artificial patch Reef (APR) telah meningkatkan tutupan karang bercabang Acropora dan berakibat terhadap meningkatnya kelimpahan ikan karang yang sesuai dengan komunitas ikan karang yang berasosiasi dengan terumbu karang alami di sekitarnya.

Strong market demand and uncontrolled exploitation and/or the inadequate management of fisheries have caused many stocks of sea cucumbers to be overexploited. One suggested effort to overcome this problem is sea ranching. Stocking density is the most important consideration in sea cucumber rearing; therefore, this present work is aimed at elucidating the best stocking density for sea ranching of Holothuria atra. H. atra was taken from the Panjang Island, Jepara waters and reared in bottom cages in Teluk Awur waters, Jepara with a density of 30, 20, or 10 individuals per cage measuring 2 m Ã— 2 m Ã— 1.8 m (with bottom area of 4 m2). Stocking times of H. atra were at the initial time of cage installation, the second and the third months after installation. Bottom sediment characteristics (i.e., chlorophyll a, b, phaeophytin, and total carotene) of the sea cucumber habitat and water quality in the cages were measured monthly during the study. The results showed that growth of H. atra fluctuated; low stocking density yielded a higher weight gain than high stocking density did. The highest weight gain was present in the density of 10 individuals/cage in the second stocking month. The highest survival rate of H. atra was seen in the condition of 30 individuals/cage (93%) at the third stocking month, which means that these sea cucumbers were only reared for three months. The highest mortality occurred at a density of 20 individuals/cage with the survival rate being low (45%) at the first stocking time or in the fifth month of rearing. There was fission evidence among H. atra reared in the cages, resulting in smaller organisms. Among the water quality parameters, the concentration of chlorophyll a, b, phaeophytin, and carotene in the sediment fluctuated according to the time of sea cucumber rearing caused by their feeding and bioturbation. The study results suggested to stock H. atra at low density during the second stocking month to get higher growth.

Sediment is a collection of particles that come from weathering both soil and rock, biological and an anthropogenic process. Sediment flows from upstream to downstream areas. Topographic conditions are one of teh factors in sedimen distribution. The topography in the Wonorejo area tends to be low because it is located in a coastal area. The purpose of this study is to determine the effects of topographic changes in Wonorejo on the distribution of sediments in the area. The method used in this study is descriptive method by collecting data including primary data and secondary data. The primary data used are Landsat 7 and Landsat 8 satellite imagery, while the secondary data used is in the form of Surabaya village administration map data, Surabaya DEM data and Indonesian SHP data. Data processing was performed using ArcGIS 10.3 software. The results indicated that the topographic conditions of the region did not have a significant influence on the distribution of sediments in the Wonorejo area. The distribution of sediment in those area was more influenced by hydro-oceanographic factors such as currents, tides and waves. Other factors that influence are anthropogenic factors such as development and land conversion

Publisher : Geological Engineering Department Universitas Gadjah Mada

Cathodoluminescence (CL) is generated by an electron gun coupled to an optical microscope. There are two types of chatodoluminescence, i.e., cold CL and hot CL. In the cold cathode microscopic equipment, the electrons are generated by an electric discharge between two electrodes under a low gas pressure, whereas in the hot CL microscope, the electrons are generated by heating a filament (2000–3000°C). In this paper we utilize cold CL combine with electron microprobe analysis (EMPA). The CL microscopy of carbonate shows at least three carbonate generations, i.e., rhodochrosite with dull or no luminescence, Mg-rich calcite with dark red luminescence, manganese-bearing calcite with up to 0.04 wt.% Mn with bright orange luminescence, and pure calcite and Mn-rich calcite (> 0.15 wt.% Mn) with dull or no luminescence. The result also suggests that the luminescence pattern of calcite is controlled by the amount of Mn2+. Sectoral zoning and chevron-shape growth zoning exist in some coarse-grained calcite aggregates. The sectorial zoning of calcite as reflected by dull to bright CL color indicated that slightly to more reducing environment during calcite deposition. Keywords: Chatodoluminescence, rhodochrosite, calcite, sectorial zoning

Blue carbon is a carbon stored in the coastal ecosystem such as mangrove ecosystems, seagrass beds and brackish/salty swamps. Seagrass ecosystems can absorb and drain large amounts of carbon from the atmosphere and deposited to tissues or sediments for a long time. The aim of this study was to determine the type, percentage of seagrass cover and carbon stocks in seagrass beds on Poteran Waters. The study was conducted in January - March 2019. Sampling was done by purposive sampling method. Carbon deposit in seagrasses was calculated using the loss on ignition (LOI) method. Seagrass species found on Poteran Island were 7 species, namely Enhalus acoroides, Thalassia hemprichii, Cymodocea serrulata, Cymodocea rotundata and Halodule uninervis, Halophila ovalis and Syringodium isoetifolium. Cymodocea serrulata had the highest density value with value 336 ind/m2 and the highest seagrass cover value was 20.45% by Cymodocea rotundata. The value of biomass under the substrate (4.24 dw.m-2 - 400.5 dw.m-2) is more than the value of biomass on the substrate (2.43 dw.m-2 - 54.52 dw.m-2). Carbon values under the substrate (1.52 gC.m-2 - 141.09 gC.m-2) and above the substrate (0.71 gC.m-2 - 5.83 gC.m-2). The carbon value in the two station was not normally distributed but did not have a significant carbon comparison value using the Mann Whitney U-Test analysis test.

Microplastics are small plastic particles that have the characteristics of easily accumulating in seawater and sediments with a diameter of less than 5 mm. The presence of microplastics in seawater and sediments may have a chain impact on marine ecosystems and humans. The purpose of this study was to determine the characteristics of microplastics in sediment and seawater in the Wulan River Estuary, Demak. Sediment and seawater samples were taken by purposive sampling at five different stations in line with the river mouth on 20 May 2021. Visual identification and counting of microplastics using a microscope, and FTIR (Fourier transform infrared) test. The highest abundance of microplastics was found in Station 2 sediment (400 particles.Kg-1) and Station 1 seawater (99 particles.L-1) which is the end of the Wulan river flow. The diversity of microplastic characteristics in the form of fragments, fibers, pellets and films, the most abundance was fragments of particles in sediment and seawater samples. The color of the microplastic particles is predominantly black and blue, with lesser number of brown, white, red, green, yellow and purple. The microplastic particle size range was found between 1.00-259.06 m. Microplastic pollutants are nitrile, nylon and PTFE (Polytetrafluoroethylene) plastics. The results of this study reveal the sources of anthropogenic pollution in the study area which are not only caused by human activities on land but also from the movement of water in the marine environment.

Desa Kaliwlingi Kabupaten Brebes merupakan daerah yang berperan penting sebagai produsen garam rebus, yaitu garam yang diproduksi dengan cara merebus air laut dan garam konsumsi di Jawa Tengah. Namun informasi mengenai kandungan bahan organik dan indeks pencemaran kaitannya dengan baku mutu air laut di tambak sebagai bahan baku garam rebus di lokasi tersebut masih terbatas. Tujuan penelitian ini untuk mengetahui kandungan padatan terlarut, kadar salinitas, pH, dan suhu di beberapa tambak Desa Kaliwlingi, Kabupaten Brebes yang digunakan sebagai bahan baku garam konsumsi dan membandingkannya dengan baku mutu bahan baku air laut garam. Metode deskriptif diterapkan dalam penelitian ini dengan materi berupa sampel air tambak di Desa Kaliwlingi yang diukur in situ pada kedalaman 1 meter sebagai sumber data total padatan terlarut (TDS), suhu, salinitas dan pH. Data kemuddian dianalisis secara kualitatif dengan indeks pencemaran dengan metode STORET yang dikeluarkan oleh Kementrian Lingkungan Hidup Republik Indonesia. Hasil penelitian mendapatkan kandungan TDS air bahan baku garam sebesar 1109-1692 mg/L, pH 7.6-8.7, kadar salinitas 16,9-19 Be pada rentang suhu 29.7-33. Kondisi tambak Desa Kaliwlingi, Kabupaten Brebes tergolong perairan yang tercemar sedang dikarenakan hampir seluruh parameter yang diujikan melewati batas baku mutu air laut untuk pembuatan garam konsumsi dan melewati indeks STORET dengan skor perairan -12. Untuk itu perlu dilakukan perlakuan untuk meningkatkan mutu air laut bahan baku garam konsumsi antara lain dengan membuat kolam sedimentasi dan kolam tandon untuk mendapatkan bahan baku yang lebih baikKaliwlingi Village, Brebes Regency is an area that plays an important role as a producer of boiled and table salt in Central Java Province. However, information regarding the content of organic matter and the pollution index in relation to the quality standards of sea water in ponds as raw material for table salt is still limited. The purpose of this study was to determine the content of dissolved solids, salinity levels, pH, and temperature in several ponds of Kaliwlingi Village, Brebes Regency which were used as raw material for salt production and to compare them with the quality standard of raw salt seawater. The descriptive method was applied in this study with the material of samples of pond water in Kaliwlingi Village which were measured in situ at a depth of 1 meter as a data source for total dissolved solids (TDS), pH, temperature, and salinity. The data was then analyzed qualitatively using a pollution index of STORET method through the Decree of the State Minister of the Environment number 115 of 2003 and the Decree of the Minister of the Environment No. 51 of 2004 concerning guidelines for determining the status of sea water quality for consumption salt raw materials..The results showed that the TDS content of raw material salt water was 1109-1692 mg.L-1, pH 7,6-8,7, salinity levels 16,9-19 ppt and the temperature range of 29,7-3,3oC. The condition of ponds in Kaliwlingi Village, Brebes Regency is classified as moderately polluted waters because almost all of the parameters tested passed the sea water quality standard for the manufacture of consumption salt and passed the STORET index with a water score of -12. For this reason, it is necessary to carry out treatment to improve the quality of seawater, among others, by setting up sedimentation and reservoir ponds to obtain better sea water as as raw materials for table salt production.
