Abstract

Ngijo Village experienced an increase in household waste which made waste management in Ngijo Village difficult. This community service activity is motivated by the increase in waste volume due to the increasing settlement and population activities in Ngijo Village. The solution to dealing with waste problems uses the circular economy concept in waste management. The circular economy concept focuses on reusing waste as raw materials for production and reducing final waste discharged into the environment. Purpose of activity: This is what underlies the importance of this service activity which aims to implement a circular economy and assist Ngijo Village's priority program regarding waste management based on magot cultivation. Method: The method used is a community empowerment approach involving students participating in the Brawijaya University MMD KKN. Service is carried out in the form of workshops and practice or training. The evaluation process at the end of the activities that have been carried out involves partners so that they can develop following the main aspects outlined in the solution offered. Results: Through this service activity, the Ngijo village community has the knowledge and ability about the importance of waste management based on maggot cultivation, carrying out a business feasibility analysis for fish/catfish cultivators using maggots as natural food. Conclusion: The conclusion of this activity is that the goal of reducing organic waste was achieved by optimizing maggot cultivation and the results of the feasibility analysis of the catfish cultivation business at the Ngijo Village TPST were declared feasible by looking at management, marketing, legal, socio-cultural, technical and operational, and financial aspects.

Abstract

Sampah Laut merupakan benda padat yang ditinggalkan di lingkungan laut, berpotensi mempengaruhi kebersihan pantai salah satunya yaitu Pantai Bahak yang terletak di Kota Probolinggo. Pantai Bahak merupakan pantai wisata, dimana kegiatan pariwisata tersebut berdampak besar bagi kualitas kebersihan pantai. Penelitian ini dilakukan untuk menganalisis kelimpahan sampah laut berdasarkan Beach Quality Index (BQI) di Pantai Bahak. Indeks kualitas pantai terdiri dari tiga yaitu Clean Coast Index (CCI), Hazardous Items Index (HII), dan Beach Grade Index (BGI) yang ditentukan dengan menghitung berbagai jenis sampah di setiap lokasi. Pengambilan sampel dilakukan menggunakan plot dengan ukuran sesuai garis pantai dan ditarik ke arah vegetasi. Sampah yang terkumpul dikelompokkan ke dalam delapan kategori (kertas, kayu, plastik, kaca, karet, kain, logam, B3). Pada penelitian ini ditemukan sebanyak 76% sampah plastik dengan volume total sampah mencapai 990 item. Berdasarkan analisis data menunjukkan bahwa Pantai Bahak memiliki nilai CCI extremely dirty dan HII berada di kategori II, sementara BGI menunjukkan keberadaan berbagai jenis sampah termasuk sampah umum (C) tanpa sampah berbahaya (A). Hal tersebut dapat disampaikan bahwa volume sampah di Pantai Bahak telah melebihi ambang batas yang sudah tetapkan oleh BQI sehingga Pantai Bahak tergolong ke dalam zona merah dan perlu dilakukan tindakan pemulihan terkait pengelolaan sampah.

Abstract

Highlight Research This is the first study of microplastics in four beach sediments in the east part of Java Island. Bahak and Pesona Beach are connected to Java Sea (north part), while Tambak Rejo and Balekambang Beach are connected to Indian Ocean (south part). A higher microplastics were observed on the beaches of the north part compared to the south part. Local sources and oceanographic parameters of the beaches influence the presence of microplastics in the study areas. Abstract Microplastic pollution in beach sediments has been studied intensively worldwide, but there are limited studies in the beach areas of the eastern Java Island, Indonesia. This study aimed to identify the distribution of microplastic in four beaches in Indonesia: Bahak, Pesona, Tambakrejo, and Balekambang. The first two beaches are located in the north of Java Island and influenced by the east Java Sea, while the last two are located in the south and influenced by the Indian Ocean. Sediment samples were collected along the strandline inside the 1 í— 1 m transect quadrate in the top 5 cm using a stainless-steel shovel. Microplastic and granulometry analyses were conducted to obtain microplastic and sediment grain size data, respectively. Physical parameters of the beaches, such as wind, wave, and ocean current, were calculated using Copernicus and NASA (PODAAC), respectively. The total abundance of microplastic ranged from 54.7 ± 48.6 to 103.3 ± 4.7 particles kg-1 with the following descending order: Bahak > Pesona > Tambakrejo > Balekambang. Although there was no statistically significant difference in microplastic concentrations among the beaches, the beaches connected to the Java Sea accumulated more microplastics than the ones connected to the Indian Ocean. Fiber and blue were the dominating type and colors of microplastic. The results confirm that the distribution of microplastic is associated with the morphology of the beaches and the local source.

Abstract

ABSTRAKPerairan Sendang Biru, Kabupaten Malang, merupakan salah satu jalur pelayaran tersibuk di pesisir selatan Jawa, terutama saat puncak musim penangkapan ikan pada bulan Agustus hingga Oktober. Aktivitas pelayaran dan perikanan intensif di wilayah ini memerlukan data batimetri yang akurat untuk mendukung keselamatan navigasi dan pengelolaan perairan. Penelitian ini bertujuan untuk memetakan kontur batimetri dan mengidentifikasi morfologi dasar laut di Perairan Sendang Biru menggunakan metode pemeruman dengan Single Beam Echosounder (SBES). Pengambilan data dilakukan pada bulan Oktober 2024 dengan interval jalur pemeruman sejauh 50 meter, menghasilkan data kedalaman yang dikoreksi terhadap pasang surut menggunakan Metode Admiralty. Pengolahan data pasang surut dilakukan berdasarkan konstanta harmonik untuk menentukan nilai elevasi penting, seperti HHWL, MHWL, MSL, MLWL, dan LLWL. Hasil analisis menunjukkan tipe pasang surut di Perairan Sendang Biru adalah tipe campuran dominan ganda dengan bilangan Formzahl sebesar 0,31744. Hasil penelitian menunjukkan bahwa kedalaman perairan berkisar antara 1 meter hingga 36 meter. Morfologi dasar laut didominasi oleh lereng landai dengan beberapa area lereng curam yang tersebar di bagian selatan dan barat daya perairan. Selain itu, terdapat beberapa wilayah yang teridentifikasi sebagai potensi pengendapan sedimen di area dangkal. Berdasarkan hasil penelitian ini, memberikan informasi penting bagi penataan alur pelayaran dan area tambat do Pelabuhan Pondokdadap, terutama karena kontur kedalaman yang bervariasi dan keberadaan zona potensi sedimentasi di area dekat pantaiKata kunci: Pemetaan Batimetri; Perairan Sendangbiru; Single Beam Echosounder (SBES); Survey Hidrografi.ABSTRACTThe waters of Sendang Biru, Malang Regency, are among the busiest shipping routes along the southern coast of Java, especially during the peak fishing season from August to October. The intensive shipping and fishing activities in this area require accurate bathymetric data to support navigation safety and water management. This study aims to map bathymetric contours and identify the seabed morphology in the waters of Sendang Biru using a hydrographic survey method with a Single Beam Echosounder (SBES). Data collection was conducted on October  2024, with survey line intervals of 50 meters, producing depth data corrected for tidal variations using the Admiralty Method.Tidal data processing was carried out based on harmonic constants to determine critical elevation values such as HHWL, MHWL, MSL, MLWL, and LLWL. The analysis results indicate that the tidal type in the waters of Sendangbiru is a mixed predominantly semidiurnal type, with a Formzahl number of 0.31744. The study results show that water depths range from 1 meter to 36 meters. The seabed morphology is dominated by gentle slopes with some steep slope areas scattered in the southern and southwestern parts of the waters. Additionally, several areas were identified as potential sediment deposition zones in shallow areas. This findings provide essential information for planning navigation routes and mooring areas at Pondokdadap Port, particularly considering the variable depth contours and presence of sedimen-accumulation zone near the coastline.
