Abstract

The agricultural sector faces significant challenges due to increasing pressure on natural resources and the need for more sustainable production systems. The linear economic model that has dominated agricultural activities has led to high levels of waste and decreased resource efficiency. In this context, implementing a circular economy is a strategic step towards creating an efficient, environmentally friendly, and competitive agricultural system. This study aims to analyze how technology integration can strengthen the implementation of a circular economy in sustainable agricultural waste management. The study used a qualitative approach, collecting data from various sources, including previous research, policy reports, and scientific publications relevant to the theme of sustainable agriculture. The data obtained were then analyzed thematically to identify the relationship between technology implementation, policy, and multi-stakeholder collaboration in supporting a circular agricultural system. The results show that transforming agricultural systems toward resource efficiency requires strong support from digital technology, adaptive public policies, and active community participation in waste management. In addition to increasing farmer productivity and welfare, a circular system also strengthens local economic resilience and environmental sustainability. Therefore, technology integration in a circular agricultural economy is a crucial pillar for realizing modern agriculture that is equitable, inclusive, and long-term resilient.

Abstract

Marine debris is defined as material that is solid, persistent, manufactured or processed, and deliberately or not-deliberately left in the marine environment. Marine debris comes in many shapes and forms, ranging in size from microscopic microplastics to large vessels. Marine debris is a big and growing global problem, pose threats to marine life sustainability. Plastic is a major component of marine debris, and single-use packaging accounts for an increasing part of the global marine debris load. Research on marine debris was conducted on coastal areas and Small Island of South Sulawesi destined for local tourism, i.e., Karama beach, Bodia beach and Mandi beach (Galesong, Takalar District), Tanjung Bayang beach, Akkarena beach and Lae-lae island/also known as Bob beach (Makassar City). This research was aimed at identifying marine debris according to its types, size, and mass. Debris was collected in a 25 x 60 m transect with direction 30 m towards land and waters, respectively, with 3 replication transects at every location, whilst collections of debris were conducted during low and high tides. Current (direction and speed) and waves (incoming direction and height) were also measured as supporting parameters. Surrounding sampling location characteristics were also recorded. The result showed that Karama beach is found with highest total marine debris mass in Takalar (36.44 kg), whilst in Makassar, the Lae-lae island was found to be the highest with debris mass (43.22 kg). Plastic was predominant debris at all sampling locations with percentages of 62.7 – 86.6%. Lastly, the predominant size was macro-debris (25-100 cm).

Abstract

Program pengabdian masyarakat bertema “Pembelajaran Antar Pulau untuk Penguatan Tata Kelola Laut dan Peningkatan Ekonomi Nelayan” dilaksanakan sebagai upaya untuk memperkuat kapasitas nelayan Pulau Bonetambu dalam memahami pengelolaan sumber daya laut berbasis masyarakat. Topik ini penting karena sebagian besar nelayan di wilayah tersebut menghadapi tantangan dalam tata kelola perikanan, terutama dalam menjaga keberlanjutan ekosistem dan peningkatan ekonomi serta degradasi ekosistem. Kegiatan ini dilaksanakan dengan pendekatan pembelajaran lintas pulau dengan perwakilan Masyarakarn Pulau Bonetambu yang melakukan kunjungan edukatif ke Pulau Langkai dan Lanjukang untuk belajar langsung dari praktik sistem buka-tutup yang telah berhasil diterapkan oleh Forum Pasibuntuluki. Metode pelaksanaan meliputi diskusi awal, pre-test, kunjungan lapangan, observasi partisipatif, refleksi, dan post-test untuk mengukur peningkatan pemahaman. Hasil kegiatan menunjukkan adanya peningkatan skor pemahaman peserta terutama dalam aspek kolaborasi, pengawasan sumber daya laut, dan kesadaran ekologis. Selain itu, nelayan mulai mengidentifikasi potensi penerapan sistem serupa di wilayahnya sendiri sebagai bentuk replikasi model pengelolaan laut berkelanjutan. Secara keseluruhan, kegiatan ini menunjukkan bahwa pembelajaran antar komunitas nelayan efektif dalam memperkuat kapasitas sosial-ekologis dan menjadi praktik baik untuk mendukung tata kelola laut yang inklusif dan berkelanjutan.

Abstract

Small-scale fisheries play a strategic role in the blue economy and food security in coastal regions. In Mallusetasi District, fishers still rely on traditional and environmentally friendly fishing gear, yet they remain vulnerable to changes in coastal ecosystems, including shrimp farming activities. This study aims to analyze the perceptions of small-scale fishers regarding the impact of shrimp pond waste on their income. A total of 40 respondents were selected through purposive sampling, and data were analyzed using a Likert scale and Spearman correlation. The Likert scale analysis produced a total score of 552, indicating that fishers perceive a decline in catch volume and income due to waste discharge and expansion of shrimp farms. However, the Spearman correlation test revealed no statistically significant relationship between shrimp farming activities and the income of small-scale fishers. These findings indicate a discrepancy between environmental perceptions and actual economic conditions, suggesting that fishers are able to adapt and maintain their income through various coping strategies. Further investigation is required to better understand the socio-economic adaptation dynamics of small-scale fishers amid the pressures of coastal aquaculture activities.
