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.

Taman Kili Kili Beach is a nesting place for turtles. There are Olive Ridley (Lepidochelys olivacea), Hawksbill Turtle (Deretmocelys imbricate), Green Turtle (Chelonian mydas) and Leatherback (Dermocelys oliacea) that found completing their natal homing to this area during the night. The beach area was conserved and managed by a group of local community that called as Pokmaswas Taman Kili-Kili Beach with consideration of the government at the village level. However, due to limitation of Pokmaswas human resources, turtle data tabulation process still conducted by filling sheet manually and it went ineffective and prone to lost. i-LENUK, an application-based on android that developed for turtle data tabulation and database system for the Pokmaswas of Taman Kili Kili introduced and applied to solved and increase effectiveness. Pokmaswas members have been trained as tabulator and administrator in the turtle data tabulation including verification and maintain data as well.

Catch biomass and time-trend perception of Beach seine fishery were studied during 2015, from four different sites in East Java: Padikde Madura, Santan Island Banyuwangi, Prigi Beach Trenggalek, and Dangkal Beach Pacitan. The study aimed to assess the impact of recently Ministerial Decree (No. 2/2015) on this particular fishery. Catch biomass was analyzed based on swept area method. Time trend perception was traced back from fishermen in relation to reduced catch biomass, catch size, habitat degradation, and income contribution from the fishery. The results showed that Beach Seines in East Java are considerably subsistence. It swept fixed-bottom habitats of 1–9 ha. Average catch biomass for all sites was 15±19.4 kg trip-1. With low price of fish catch, fishermen cannot place down their family income solely from this livelihood. Beach seine is more as to maintain tradition of subsistence. Fishermen clearly observed the reduced in catch biomass and catch size compared to what it used to be (±30 years ago). With very low contribution to total catch in the region, negligible impact to habitat degradation, and consumed no fuel subsidy, it is no real reason to include this gear in general ban through Ministerial Decree of Marine Affairs and Fisheries.

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.

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.
