Abstract

The mangrove forests in the Prigi Gulf located in Damas beach and Cengkrong beach. In one decade, the mangrove forest area has decreased quite dramatically. The decreasing is the result of land conversion activities as oil plantations. This study aimed to describe the management of mangrove forests, the identifying mangrove vegetation, and analyze the mangrove-based business opportunities that can be developed.Mangrove fruit actually can be used as syrup’s ingredient. But it’s at an early stage. In order to reduce the destruction of forests mangrove, several things as introduces mangrove functions as coastal life support and mangrove benefit directly as a material that can be developed for productive business. Based on the data, mangrove can be used for making some product such as batik, brownies and crackers. Feasibility analyses show that batik mangrove have an NPV value of Rp. 73,101,417, IRR 352.79%, Net B/C 19.93 and Pay Back Period 0.8. Brownies has a value of Rp 8,413,444 NPV, IRR 29.01%, Net B / C 1.78 and Pay Back Period 3.18. Crackers have a value of Rp 8,094,869 NPV, IRR 62.21%, Net B / C 3.54 and 1.59 Pay Back Period. Based on these values, the mangrove processing business is feasible and can be developed for productive business.Keywords: land use, mangrove-based business feasibility

Abstract

Characteristics of plastic debris were assessed among two types of beaches on Bawean Island (windward and leeward) to analyze its sources and long-term effects. Plastic debris was collected inside a 5 x 5 meter transect with five transect plots on each beach per 20 meters. Samplings were carried out three times at intervals of seven days from six different beaches. The average abundances of plastic debris were almost similar between leeward (0.1690.123 pcs m-2) and windward beaches (0.8410.577 pcs m-2). On the other hand, in terms of weight, leeward beaches contained a very low value of debris (0.9270.746 g m-2) compared to windward beaches (4.4793.551 g m-2). Sheets on the windward beaches and wholes on the leeward beaches dominate the shape of plastic debris with the average size was 1520 cm. The color on both type of beaches was dominated by white (38%) and blue (12%). The weathering intensity is 48% on the leeward beach and 52% on the windward beach. The absence of significant differences in size, color, and weathering intensity implies that the debris found came from the same source. The large size and low weathering intensity of the plastic debris means that the debris has not been exposed to hydro-oceanographic factors for an extended period and they came from a local source. The difference in abundance and shape of plastic debris suggests that wind still plays a vital role in shaping the characteristics of plastic debris on Bawean Island.Keywords:Marine DebrisPlastic WeatheringWind DirectionMarine PollutionMacroplastic

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberikan pendampingan dalam pengembangan dan analisis kelayakan usaha kerupuk ikan pada home industry Abizar di Desa Pangkahkulon Ujung Pangkah-Gresik dari berbagai aspek. Pendampingan dilakukan dengan beberapa kegiatan antara lain pengenalan dan pemberian bantuan alat produksi, pelatihan pemasaran, dan pelatihan pengelolaan keuangan. Sedangkan analisis kelayakan usaha ditinjau dari beberapa aspek yaitu aspek teknis produksi, manajemen, pemasaran, legalitas dan aspek keuangan. Hasil analisis menunjukkan bahwa UKM secara umum layak dijalankan dari berbagai aspek di atas. Dari aspek finansial yang menjadi indikator utama kelayakan usaha, terdapat profit ratio yang sangat besar, Net B/C ratio yang mencapai 5,05, Profitabilitas 40%, dan R/C Ratio 1,5 serta payback period kurang dari setengah. setahun, maka usaha ini layak untuk diusahakan dan dapat dilanjutkan. Berdasarkan studi kelayakan usaha juga dapat disimpulkan bahwa pendampingan usaha dengan memberikan bantuan alat produksi tidak memberikan beban keuangan baru bagi pengusaha tetapi justru meningkatkan efisiensi dan keuntungan usaha. Namun masih perlu pembenahan terutama dari aspek legalitas usaha karena UKM mitra belum memiliki legalitas sama sekali.

Abstract

Penelitian ini bertujuan untuk menganalisis efisiensi teknis diantara petambak udang dengan menggunakan pendekatan stochastic frontier yang digabungkan dengan model efek inefisiensi. Data dikumpulkan dari 245 sampel petambak udang di Kabupaten Lamongan, Banyuwangi, dan Pacitan menggunakan kuesioner terstruktur. Hasil empiris menunjukkan bahwa tenaga kerja, pupuk, pakan buatan dan padat penebaran adalah faktor-faktor yang mempengaruhi variasi dalam output. Hasil analisis menunjukkan bahwa 68% () kesalahan acak yang dihasilkan oleh model disebabkan oleh inefisiensi yang terjadi dalam proses produksi udang vaname. Skor efisiensi teknis petambak udang bervariasi, berkisar antara 0,77 - 0,97 dengan rata-rata 0,92. Faktor-faktor yang mempengaruhi inefisiensi teknis dalam budidaya udang vaname di daerah penelitian diduga berasal dari atribut yang melekat pada petambak udang seperti umur, tingkat pendidikan, dan pengalaman dalam budidaya vaname
