Abstract

Kawasan pesisir Jawa Timur memiliki beberapa lokasi pendaratan dan peneluran penyu, akan tetapi pada saat ini belum terdapat data komprehensif yang menggambarkan kondisi dan sensitivitas kawasan tersebut terhadap ancaman perubahan iklim. Fenomena cuaca ekstrim di Samudera Hindia timur pada kurun waktu 2016 – 2018 diduga memberikan dampak terhadap pantai peneluran penyu di pesisir Jawa Timur. Penelitian ini dilakukan untuk mengidentifikasi kondisi fisik dan pengelolaan pada 6 lokasi utama peneluran penyu di pesisir Jawa Timur. Taman Nasional Alas Purwo dan Taman Nasional Meru Betiri merupakan kawasan konservasi penyu yang dikelola oleh pemerintah, sedangkan lokasi lainnya merupakan lokasi peneluran penyu yang dikonservasi oleh kelompok masyarakat, diantaranya Pantai Taman Ria (Pacitan), Pantai Kili Kili (Trenggalek), Pantai Pathuk Gebang (Tulungagung) dan Pantai Bajulmati (Malang). Kegiatan observasi lapangan dilaksanakan pada Tahun 2017 dan 2018. Variabel pengamatan meliputi perubahan fisik pantai akibat cuaca ekstrim, sementara analisis komponen eksposur dan sensitivitas habitat didapatkan dari pengukuran variabel temperatur substrat, serta event siklon dan anomali SPL. Hasil penelitian menunjukkan cuaca ekstrim berupa gelombang tinggi dan banjir pasang yang menyebabkan adanya fitur abrasi dan pergeseran lokasi peneluran pada pantai pendaratan penyu. Curah hujan yang tinggi pada musim peneluran menyebabkan suhu substrat berada pada rentang bawah pivot (25 – 28◦C) dengan kelembaban bervariasi. Walaupun begitu, belum terdapat bentuk manajemen adaptif terhadap perubahan iklim pada seluruh area konservasi penyu di Jawa Timur.

Abstract

Sargassum sp. dikenal sebagai salah satu sumber hayati yang memiliki kandungan senyawa bioaktif yang berpotensi sebagai bahan esesnsial industri. Namun, komoditi ini kurang bernilai ekonomis sehingga perlu eksplorasi secara optimal untuk meningkatkan nilai ekonomisnya. Salah satu potensi yang dapat dikembangkan adalah aktivitas fotoprotektif yang dimiliki oleh Sargassum sp. Tujuan dari penelitian ini adalah untuk mengeksplorasi aktivitas fotoprotektif Sargassum sp. terhadap paparan sinar UV-B dan UV-A. Potensi fotoprotektif diperoleh dari hasil pengujian nilai SPF (Sun Protection Factor), %Te dan %Tp dari tiga ekstrak Sargassum sp. menggunakan jenir pelarut yang berbeda (methanol, etil asetat dan nheksana). Hasil penelitian menunjukkan bahwa ketiga ekstrak memiliki aktivitas fotoprotektif (SPF) bersifat ultra pada konsentrasi 1100 ppm dan memiliki efek perlindungan (%Te dan %Tp) sebagai Sunblock pada konsentrasi 1100 ppm ekstrak Sargassum sp. Namun dari ketiga ekstrak, ekstrak dengan pelarut etil asetat (ESE) menunjukkan nilai SPF yang tertinggi (32,63) dan nilai %Te (0,055) %Tp (0,075) terendah pada konsentrasi yang sama. Semakin tinggi nilai SPF menunjukkan sifat fotoprotektif yang semakin baik, sedangkan semakin rendah nilai %Te dan %Tp menunjukkan efek perlindungan yang semakin baik. Sargassum sp. known as one of the biological sources that contain bioactive compounds. These compounds have the potential to be industrial essential ingredients. However, this commodity is less economically valuable, so it is important to explore its bioactive compounds in order to increase its economic value. One of the potentials that can be developed is its photoprotective activity. The study aimed  to explore the photoprotective activity of Sargassum sp. against exposure of UV-B and UV-A rays. The photoprotective activity was obtained from the results of the SPF (Sun Protection Factor), % Te and % Tp values of three different Sargassum sp. extracts (methanol, ethyl acetate, and n-hexane). The results showed that the three extracts had an ultra-photoprotective activity (SPF) at a minimum concentration of 1100 ppm and had a protective effect (% Te and% Tp) as sunblocks at the same minimum concentration of 1100 ppm. Among these three extracts, the ethyl acetate extract (ESE) showed the highest SPF value (32.63) and the lowest % Te (0.055) % Tp (0.075) value, at the same concentration. The higher SPF value indicates the better photoprotective properties, while the lower % Te and% Tp values explain the better protective effect.

Abstract

Mikroalga merupakan salah satu komponen penyusun perifiton yang hidupnya melekat pada substrat, baik substrat alami maupun substrat buatan. Perifiton memiliki peran salah satunya sebagai bioindikator. Penelitian ini bertujuan untuk menganalisis komunitas mikroalga perifiton pada substrat berbeda yaitu substrat alami (batu) dan substrat buatan (kaca objek glass) serta untuk menganalisis status mutu perairan berdasarkan pendekatan perifiton. Lokasi penelitian yaitu perairan Ranu Pakis Lumajang dengan 3 stasiun pengambilan sampel secara purposive sampling. Metode penelitian adalah survei dan dilakukan pada musim barat tahun 2019 dengan waktu pengambilan sampel setiap dua minggu sekali selama enam minggu. Parameter yang dianalisis meliputi identifikasi mikroalga perifiton, penghitungan kelimpahan, indeks biologi, dan pengukuran kualitas air. Data yang diperoleh dianalisis secara statistik menggunakan one way ANOVA dan regresi linear berganda menggunakan Ms. Excel dan SPSS 23.0. Hasil penelitian menunjukkan bahwa mikroalga perifiton yang ditemukan berasal dari empat divisi yaitu Chrysophyta (47%), Chlorophyta (27%), Cyanophyta (26%), dan Pyrrophyta (0,2%). Secara keseluruhan kelimpahan yang diperoleh berkisar antara 5.567-34.841 sel/cm2 (substrat alami) dan 14.367-42.563 sel/cm2 (substrat buatan). Indeks keanekaragaman di perairan Ranu Pakis tergolong tinggi sehingga perairan tergolong bersih (stabil), kecuali pada stasiun 3 tergolong tercemar ringan (kurang stabil). Akan tetapi, tidak ada dominansi pada seluruh stasiun tersebut. Hasil pengukuran parameter kualitas air menunjukkan bahwa secara umum nilai kualitas air masih berada di bawah ambang baku mutu yang ditetapkan oleh pemerintah PP No.82 Tahun 2001 untuk kegiatan perikanan kelas III. Komponen kualitas air seperti karbondioksida, kecerahan, nitrat, orthofosfat, dan suhu secara simultan berpengaruh terhadap kelimpahan mikroalga sebesar 39,7%.Periphyton microalgae  live by attaching to the substrate, both natural and artificial substrate. Perifiton plays role as an aquatic environment bioindicator. This study aimed to analyze periphyton microalgae community in different substrate, natural substrate (stone) and artificial substrate (objeck glass). Furthermore, the microalgae periphyton are used to analyze the environmental status quality. Survey method was used and sampling location is in three site of the Ranu Pakis environment by purposive sampling. Research was carried out in 2019 every two week during six weeks on west season. Identification of periphyton microalgae, density counting, biological indexes, and water quality measurements was taken during the research. All data was analyzed statistically by using one way ANOVA and multiple linear regression by using Ms. Excel and SPSS 23.0. The results depict periphyton microalgae consists of Chrysophyta (47%), Chlorophyta (27%), Cyanophyta (26%), and Pyrrophyta (0,2%). The density of microalgae periphyton was ranging from 5.567 to 34.841 sel.cm-2 (natural substrate) and 14.367 to 42.563 sel.cm-2 (artificial substrate). Biological index indicates that Ranu Pakis environment was belonging to stable (unpolluted) in site 1 and 2, while 3 was belonging to less stable (less polluted). However, there was no domination in all sites. Water quality values provide information that in general it still under of quality standards determined by PP No. 82 year 2001 for fisheries activites class III. Water quality components  including carbondioxide, transparency, nitrate, orthophosphate, and temperature simultantly influence the microalgae density of 39,7%.

Abstract

Estuaries are biogeochemical hot spots; they receive large inputs of nutrients from land and oceans to support high primary productivity rates. Estuaries also as a place for waste disposal allowing the accumulation that endangers the environment and organisms. Water quality assessment can be done by analyzing physical, chemical, and biological characteristics using microalgae. This study aimed to analyze the microalgae community as aquatic environment bioindicator. Survey method was used and sampling location was in four different sites of Peniti Estuary by purposive sampling. Identification of microalgae, density, biological indexes, and water quality measurements was taken in this research. The result showed microalgae community consists of 68 genera and Euglenophyceae was a component of microalgae with the highest percentage of abundance (60.93%). The most commonly found genera were Trachelomonas, Phacus, Lepocinclis, and Sphaerellopsis. The abundance of microalga was ranging from 0.5-2141.5 ind/L. Biological indexes indicate that Peniti estuary environment was belonging to moderately polluted and water eutrophication. The abundance of microalgae was influenced by physico-chemical factors such as temperature, current, nitrate and phosphate content.

Abstract

Tulungagung reflects the typical conditions of southern coast of Java, which dominated bay small bays with thin layer of superficial mud sediments and bordered by hilly terrain. Mangrove distribution in Tulungagung located in there locations, Brumbun Beach, Gerangan Beach and Sine Beach. This research aimed to identify the forest structure, habitat sensitivity and completed with management plan in each location. Data collected includes vegetation structure, hydrooceanography, environmental pressure and anthropogenic activities. An interesting finding is that, despite its narrow areas (2,24 Ha), mangroves in Tulungagung have high species diversity (11 species of true mangrove includes Acanthus ebracteatus, Acanthus ilicifolius, Acrostichum aureum, Avicennia alba, Avicennia marina, Ceriops tagal, Excoecaria agallocha, Rhizopora apiculata, Rhizopora mucronata, Rhizopora stylosa dan Sonneratia alba). Rm and Rs stands dominated by >7m height with canopy cover range from 79,4-89,6%. Geomorphological settings and limited mud supply are the primary challenges for mangrove habitat in Tulungagung. On the other hand, observation conservation status and local stakeholders involvement show the need for improvement of mangrove management in Tulungagung coastal areas.

Abstract

The quality of the river changes according to the development of the surrounding environment which is influenced by various human activities. Analysis of factors affecting Dissolved Oxygen (DO) at Bengawan Solo River is crucial for river management purpose and pollution control. Previous research suggested the use classic multiple linear regression. However, DO measurement were usually took place of sampling sites along the river channel. Therefore, there is a high chance that the measurements results may spatially correlated. As the consequence, the utilization of multiple linear regression technique for the dataset can be inappropriate. In this paper, we applied a modification of multiple linear regression model to incorporate with spatial autocorrelation that exist in the data by adding control variable such vector eigen to the model which known as Spatial Filtering with Eigenvector (SFE). The results showed that nitrate and nitrite were the predictor variables that have a negative and significant effect. However, the model contains spatial autocorrelation. The application of SFE technique by adding three eigenvectors as control variables in the model succeeded in making the residual model free from spatial autocorrelation. However, a new problem arose where there was a violation of the non-heteroscedasticity assumption.
