High-quality marine ecosystems are free from global trending pollutants’ (GTP) contaminants. Accuracy and caution are needed during the exploitation of marine resources during marine tourism to prevent future ecological hazards that cause chain effects on aquatic ecosystems and humans. This article identifies exposure to GTP: microplastic (MP); polycyclic aromatic hydrocarbons (PAH); pesticide residue (PR); heavy metal (HM); and medical waste (MW), in marine ecosystems in the marine tourism area (MTA) area and Barrang Caddi Island (BCI) waters. A combination of qualitative and quantitative analysis methods were used with analytical instruments and mathematical formulas. The search results show the average total abundance of MPs in seawater (5.47 units/m3) and fish samples (7.03 units/m3), as well as in the sediment and sponge samples (8.18 units/m3) and (8.32 units/m3). Based on an analysis of the polymer structure, it was identified that the dominant light group was MPs: polyethylene (PE); polypropylene (PP); polystyrene (PS); followed by polyamide-nylon (PA); and polycarbonate (PC). Several PAH pollutants were identified in the samples. In particular, naphthalene (NL) types were the most common pollutants in all of the samples, followed by pyrene (PN), and azulene (AZ). Pb+2 and Cu+2 pollutants around BCI were successfully calculated, showing average concentrations in seawater of 0.164 ± 0.0002 mg/L and 0.293 ± 0.0007 mg/L, respectively, while in fish, the concentrations were 1.811 ± 0.0002 µg/g and 4.372 ± 0.0003 µg/g, respectively. Based on these findings, the BCI area is not recommended as a marine tourism destination.

A quality marine ecosystem if it is free from GTP contaminants. Accuracy and caution are needed in the exploitation of marine resources as marine tourism destinations so that in the future, there will be no ecological hazards that cause chain effects, not only on aquatic ecosystems but also on humans. This article identifies exposure to GTP (MP, PAH, PR, HM, MW) in marine ecosystems in the MTA area and BCI waters. The combination of qualitative and quantitative analysis methods uses a combination of analytical instruments and mathematical formulas. The search results show the average total abundance of MP in seawater and fish samples (5.47 units/m3) and (7.03 units/m3), respectively, while in sediment and sponge samples (8.18 units/m3) and (8.32 units/m3). Based on the analysis of the polymer structure, it was identified that the dominant light group MP (PE, PP and PS), followed by PA and PC. Several PAH pollutants were identified in the samples, especially NL types found in all samples, followed by PN and AZ. BCI sea waters are suspected to be exposed to MW and PR. Pollutants of Pb+2 and Cu+2 around BCI were successfully calculated with average concentrations in seawater 0.164 mg/L and 0.294 mg/L, respectively, while in fish, 1.8110 µg/g and 2,452 µg/g, respectively. Based on these findings, the BCI area is not recommended as a marine tourism destination.

The purpose of this research was to obtain an overview and analyze the patterns of economic development in the village of Bunder, Pademawu Pamekasan District. The research employed descriptive analytical-qualitative methods. The research illustrated that the village of Bunder was a village on the coast with considerable salt potential. The majority of the people earned their living as salt farmers. Based on the Pamekasan Regent program to facilitate the management and economic development in the village, a thematic village was formed, the formation of these thematic villages based on the local potential of the region. Therefore, the village of Bunder was designated as "Village of Salt". The wealth and beautiful panorama of salt in this village motivated the community to build a "Salt Edu-tourism", a tourist destination besides conducting salt recrystallization efforts with a boiled salt system. The conclusion of the research was that the economic development of the village through the salt village was a form of competitive economic development.Tujuan dilakukan penelitian ini adalah untuk mendapatkan gambaran dan menganalisis pola pengembangan ekonomi desa di Desa Bunder Kecamatan Pademawu Pamekasan. Penelitian menggunakan metode deskriptif analitis kualitatif. Penelitian ini menggambarkan bahwa Desa Bunder merupakan   desa di pesisir dengan potensi garam yang cukup besar. Mayoritas masyarakatnya bermata pencaharian sebagai petani garam. Berdasarkan program Bupati Pamekasan untuk memudahkan dalam pengelolaan dan pengembangan ekonomi di desa perlu dibentuk desa tematik, pembentukan desa tematik ini berbasis potensi lokal wilayah tersebut. Oleh karena maka Desa Bunder ditetapkan sebagai “Kampung Garam”. Kekayaan dan panorama garam yang indah di desa ini memberikan motivasi kepada masyarakat untuk membangun sebuah destinasi “Eduwisata Garam” selain itu juga dilakukan usaha rekristalisasi garam dengan sistem garam rebus. Simpulan penelitian bahwa pengembangan ekonomi desa melalui kampung garam adalah sebagai bentuk pembangunan ekonomi yang berdaya saing.

Sweet potato has the potential to be developed for diversified food consumption programs as a source of carbohydrates, nutrients, with a small risk of failure, low production costs, various processed products, food providers, industrial raw materials, and animal feed. This research aimed to analyze sweet potato farming economically and socially. The study was carried out quantitatively using a survey method. The research was conducted in Lamongan Regency, East Java, Indonesia. The location was chosen purposively. The sampling method was carried out using census in Kalitengah and Kedungpring Districts, in 6 villages, with 348 respondent farmers. The data analysis employed Revenue Cost (R/C) and descriptive analysis. The results revealed that 80.46% of farmers did not complete elementary school. Farmers with experience in sweet potato farming over 20 years reached 67.53%. Their income from total farm costs was IDR 5,178,296, with an R/C ratio is 1.89. Sweet potato farming is profitable and feasible to develop. The utilization of small sweet potato tubers affected by Cylas Formicarius disease as a fish feed was carried out by 19.54% of the farmers. Meanwhile, 51.72% of the farmers utilized sweet potato stalks and leaves as goat feed.
