Indonesia's environmental services and natural resources have great potential both on land and sea, especially for tourism purposes. One of the tourism sectors comes from coastal tourism. The development of coastal tourism areas must lead to a planned development in a comprehensive manner so that optimal benefits can be obtained for the community. The research was conducted in Labuhan village which is one of the coastal villages in Lamongan Regency. The method used was survey and observation methods coupled with closed interviews with questionnaires, while natural parameters were carried out by field observation. The research aims to analyze, choose the right type of tourism activity according to the suitability index of the type of tourism activity on Kutang beach, Labuhan village, Brondong District, Lamongan Regency. Data analysis was done by means of multi criteria analysis. This analysis is developed based on utility theory, with the assumption that a person's total (composite) utility is formed as an aggregate of the many attributes (components) that make up the utility. The type of tourism activity which is categorized as very suitable or feasible to do in the Kutang beach area is in the form of tracking activities with a suitability value of 84% and Safari Photo of 83%. Alternative types of activities (according to condition) are Canoeing with a suitability value of 80%, fishing and culinary 77% and swinging 74%.

Abalone is one of aquaculture commodity that has a high value including in Indonesia due to its price, taste and nutrition content. Unfortunately there is problem in abalone's transportation process which caused stress and even death. Clove oil can be used as anesthetic agent for abalone to obtain a high survival rate because of its eugenol content. This research tried to evaluate the the effect of clove oil as anesthesia agent to determined induction time, survival rate and oxygen cosumption in H squamata. This study used an experimental method and used a completely randomized design with treatment concentration of clove oil solution were 0.5 ml/L (A), 0.7 ml/L (B), 0.9 ml/L (C), and 1.1 ml/L (D) which each treatment was repeated three times, and calculated the value of the abalone (H. Squamata) survival rate after maintenance for 14 days. The results of the study showed that the survival rate of abalone seeds obtained in the treatment with the concentration of 1.1 ml/L (D). In the treatment also showed the fastest induction time with 96.67 seconds. The lowest oxygen comsumption rate in this study was treatment D with concentration of 1,1 ml/L. It could be concluded that using clove oil with concentration of 1.1 ml/L as anasthesic compound for abalone showed effectiveness in induction time, survival rate, and oxygen consumption rate.

Waduk Joto merupakan waduk yang berada di Kabupaten Lamongan yang biasa digunakan oleh masyarakat sekitar untuk aktifitas sehari-hari. Selain itu aliran air waduk juga digunakan untuk kegiatan perikanan dan pertanian. Dalam pengelolaan suatu perairan yang lestari dan berkelanjutan diperlukan informasi dasar mengenai tingkat kesuburan perairan guna pemanfaatan yang tepat. Penelitian ini bertujuan untuk mengetahui kualitas air dan status kesuburan perairan di Waduk Joto Kabupaten Lamongan. Metode pengumpulan data menggunakan purposive random sampling pada tiga stasiun yaitu bagian inlet, tengah, dan outlet. Penentuan status kesuburan perairan berdasarkan perhitunganmenggunakan Carlson Trophic State Index (TSI). Pengambilan sampel air dilakukan dengan interval waktu satu bulan sekali selama 3 bulan pada bulan Desember 2020 sampai Februari 2021. Parameter yang diamati meliputi suhu, kecerahan, pH, salinitas, oksigen terlarut (DO), nitrat, total fosfat, klorofil-a. Hasil penelitian menunjukkan bahwa status kesuburan perairan Waduk Joto pada bulan Desember 2020 – Februari 2021 berdasarkan TSI Carlson termasuk dalam kategori perairan hipereutrofik dengan nilai sebesar 74. Disarankan untuk melakukan penelitian lanjutan pada musim yang berbeda untuk mengetahui status kesuburan perairan di musim kemarau.

This research aimed to determine the species composition of fishes in the Kaliotik River, Lamongan Regency. The sampling was conducted from March to May 2020 at four stations. A total of 1031 samples caught by the fishing net during the study consists of Anabas testudineus, Trichogaster trichopterus, Hyposarcus pardalis, Mystus sp., Channa striata, Oreochromis mossambicus. The fish diversity index values indicated that the river is in low to moderate condition. The species was also slightly evenly distributed in the waters with no dominant species. Trichogaster sp. and Anabas testudineus are the two dominant species found in the waters with a relative abundance of 44 % and 41 %, respectively. The Kaliotik River ecosystem balance was affected by disposal from human activities along the riverbank.

Rawa Sier-Sier merupakan bendungan tempat bertemunya aliran sungai Desa Sogo, aliran air dari lereng Gunung Pegat, dan aliran Sungai Konang. Rawa Sier-Sier adalah salah satu rawa bendungan yang berada di Kecamatan Babat Kabupaten Lamongan. Rawa ini termasuk rawa buatan dengan luas 3,5 km2 dan kedalaman 7 m. Kelimpahan eceng gondok yang sangat tinggi berdampak pada kualitas air di perairan tesebut. Penelitian ini bertujuan untuk mengetahui kualitas air dan sebagai informasi kepada masyarakat guna menjaga serta mengelola sumberdaya perairan yang berkelanjutan. Penelitian ini menggunakan teknik sampel acak berstrata atau Stratified Random dengan tiga titik pengamatan. Titik pengamatan pertama terdapat di Rawa Sier-Sier bagian selatan tempat masuknya air sungai Desa Sogo dan Lereng Gunung Pegat. Titik pengamatan kedua berada dibagian tengah Rawa Sier-Sier tempat bertemunya antara air dari Sungai Sogo dan Sungai Konang. Titik pengamatan yang ketiga berada di Rawa Sier-Sier bagian barat tempat masuknya aliran sungai Konang. Data yang diambil meliputi suhu, kedalaman, kecerahan, salinitas, pH, DO, Nitrat, Nitrit dan Fosfat perairan. Hasil analisis menunjukkan bahwa distribusi dalam perairan Rawa Sier-Sier tidak merata. Nilai rata-rata yang di dapat yaitu suhu 28oC, kedalaman 1,96 m, kecerahan 1,33 m dan salinitas 0‰. Kandungan nitrat  (NO3- N) dalam air  rata-rata 4,3 mg/l, dan nitrat (NO3) rata-rata 3,06 mg/l. Adapun kandungan fosfat (PO4) rata-rata yaitu 3,96 mg/l dan fosfat (PO4-P) 1,35 mg/l.
