Abstract

Kegiatan ini dilakukan dengan menginduksikan metode Continuously Dynamic Mixing (CDM) yang diterapkan dalam Greenhouse Salt Tunnel (GST) untuk mengkreasi produksi garam di Pantai Selatan Kabupaten Malang. Mitra kegiatan ini adalah Kelompok Usaha Garam Rakyat (Kugar) Bajulmati Sejahtera yang merupakan kelompok usaha garam pertama di Kabupaten Malang. Mitra memiliki masalah terkait dengan teknis produksi garam untuk menghasilkan garam yang berkualitas baik (NaCl > 95%). Indikator keberhasilan kegiatan pengabdian kepada masyarakat ini adalah: 1) teknologi GST di lokasi mitra sudah menggunakan metode CDM untuk produksi garam; 2) peningkatan pengetahuan dan keterampilan mitra dalam pengaturan air dalam metode CDM dalam GST; dan 3) Mitra dapat memproduksi garam berkualitas K-1 dengan peningkatan kapasitas produksi lebih dari 50%. Kegiatan pengabdian kepada masyarakat ini telah dapat mengkreasi produksi garam untuk pertama kali di Pantai Selatan Kabupaten Malang.

Abstract

Koi fish aquaculture sector is closely tied to risk. Various factors, such as delays and uncertainties in delivering feed, infections, and pests affecting the koi fish due to irregularities in pond cleaning, delays and improper feeding, and extreme weather conditions, can lead to the death of fish. It is crucial to monitor the increasing risks diligently, as inadequate risk management procedures can lead to losses and potentially disrupt the growth of the industry. The purposes of this risk management on koi fish hatchery production are: 1). Identify and define risk events and risk agents in koi fish farming production in Kediri Regency, 2). Analyze risk events and risk agents in the production of koi fish in Kediri Regency. 3). Analyzing risk management in koi fish aquaculture in Kediri Regency. The proportional sampling method was used to choose the research sample. The House of Risk (HOR) data analysis method was employed in this study to analyze data. Based on the data analysis, a total of 17 risk events were identified in the four processes of koi fish seed production, which consist of risk events in the pond preparation process, risk events in the spawning process, risk events in the maintenance process, and risk events in the harvesting process. These risk events are caused by 33 risk agents.

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
