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

Pulau Gili Ketapang memiliki jumlah potensi sumberdaya perikanan mencapai 40%, sehingga Gili Ketapang berpotensi menjadi daerah perikanan dengan sumberdaya yang cukup tinggi dan pelayaran yang cukup padat. Hal ini berarti informasi mengenai batimetri di perairan tersebut bermanfaat untuk mengetahui kondisi perairan, baik secara langsung maupun tidak langsung. Penelitian ini dilakukan untuk mengetahui tingkat akurasi data batimetri dari Singlebeam Echosounder System (SBES) dan citra satelit SPOT-7, sehingga dapat digunakan sebagai referensi kedalaman perairan. Teknik yang digunakan dalam penelitian ini merupakan Satellite Derived Bathymetry (SDB) metode klasifikasi Random Forest dengan menggunakan software Satellite Derived Bathymetry (SDB) GUI. Kedalaman perairan di Pulau Gili Ketapang berdasarkan hasil pemeruman berkisar antara 0-30m. Profil kedalaman perairan pada peta batimetri 3D menunjukkan bahwa morfologi dasar laut tidak rata. Profil kedalaman dari garis pantai hingga jarak 200 m memiliki nilai kedalaman 0-20 m, sedangkan profil kedalaman dari jarak 200m hingga perairan terbuka cukup bervariasi. Klasifikasi kelas lereng di perairan Pulau Gili Ketapang didominasi oleh kategori datar sebesar 77,28%. Hasil regresi (R²) pada model SDB antara data citra dengan data insitu yaitu 0,59 atau 59%. Nilai RMSE yang tertinggi terdapat pada kedalaman 0 – 5m yaitu 0,87, sedangkan yang terendah pada kedalaman 15,1 - 20m yaitu 1,31.
