Abstract

System of Rice Intensification (SRI) by a Local Microorganisme Usage (MOL) in Producing the Compost Fertilizer (Case Study at Desa Sidodadi Kabupaten Deli Serdang) is expected to maintain the fertile of land, improve land microbia population and to preserve the environment at once capable to maintain or improve land productivity. The agriculture system with SRI is applied by using organic material such as fruif waste whis is fermented to produced MOL used as decomposer in composing proges. This reseach studied microbia population where an organik agricaltural system (SRI) has been applied. The reseach was comparedl of mikroba population soil also whith how effect SRI aplication between chemical fertilizer  for the managemental in Sidodadi village.Using compost MOL at SRI improved microbia  population soil by the result of soil analysis either chemically and biologically the uses of MOL compost is far better compared for environmental the uses of an-organic fertilizer. The SRI pattern practiced at Desa Sidodadi was an agricultural work  environmentally friendly using organic fertilizer as source of nutrients improve physical, chemical and biological properties of soil as well in increasing production yield.

Abstract

Kajian dilakukan bulan Oktober 2023 pada 5 stasiun pengamatan yang bertujuan untuk menilai kondisi ekologi perairan Selat Cunda dalam upaya pengembangan budidaya tiram. Parameter diukur secara in situ dan ex situ, selanjutnya dibandingkan dengan baku mutu lingkungan serta dianalisis menggunakan Principal Component Analysis. Oksigen terlarut tertinggi ditemukan pada Stasiun 3 (7.66 ± 0.08 mg/L), pH pada Stasiun 2 (7.95 ± 0.02), salinitas pada Stasiun 1 (27.00 ± 1.00‰), kecerahan pada Stasiun 5 (79.00 ± 4.00 cm), kedalaman dan suhu pada Stasiun 2 (62.33 ± 8.33 cm dan 30.80 ± 0.62⁰C), kekeruhan dan kelimpahan Escherichia coli pada Stasiun 1 (2262.42 ± 1613.32 NTU dan 1020.00 ± 113.00 MPN/100 ml), logam berat Cd air pada Stasiun 3 dan 4 (masing-masing 0.01 ± 0.00 mg/L), logam berat Pb air pada Stasiun 3 (0.07 ± 0.01 mg/L), kecepatan arus pada Stasiun 2 (0.20 ± 0.01 m/s), tekstur pasir pada Stasiun 5 (88.00 ± 1.73%), tekstur debu pada Stasiun 4 (46.00 ± 22.52%), tekstur liat dan C-organik pada Stasiun 1 (9.67 ± 1.15% dan 0.85 ± 0.68%), logam berat Cd serta Pb pada Stasiun 3 (0.03 ± 0.01 mg/L dan 7.60 ± 0.58 mg/L) dan N-total pada Stasiun 4 (0.12 ± 0.33%). Hasil analisis PCA memperlihatkan bahwa parameter suhu, tekstur debu, kecepatan arus, Cd air, N-total dan tekstur pasir merupakan pembeda utama variasi di PC pertama; sementara parameter salinitas, kelimpahan E. coli, kekeruhan, tekstur liat dan kedalaman merupakan pembeda utama variasi di PC kedua. Untuk mewujudkan kesuksesan budidaya tiram di Selat Cunda Kota Lhokseumawe harus ditingkatkan nilai kecerahan dan kedalaman perairan serta menurunkan kekeruhan serta logam berat Pb.

Abstract

Lhokseumawe is a designated as an Economic Growth Center (EGC), making it very susceptible to producing heavy metals.This research aimed to measure the content of lead (Pb) and cadmium (Cd) in oysters (Saccostrea cucullata), water, and sediment in the Cunda Strait, as well as evaluate the relationship between heavy metals and environmental conditions. The experiment was conducted at five stations selected based on considerations of seawater inflow and outflow into the Cunda Strait and existing pollution sources. The results showed that high levels of Pb and Cd with 0.36 and 0.00 mg.kg-1 for S. cucullata, 0.07 and 0.01 mg.kg-1 for water, as well as 7.60 and 0.03 mg.kg-1 for sediment, were found at locations away from the inflow and outflow of the Malacca Strait. The analysis showed a positive pattern in the relationship between Pb metal levels in S. cucullata with water and sediment. This suggested that Pb pollution in S. cucullata came from Pb metal in sediment and water, showing a significant effect on aquatic organisms. However, no clear relationship was found between Cd metal in S. cucullata with sediment and water. The main differences in Pb and Cd between parts were observed in the levels of Pb in water (r= 0.59) and Cd in water (r= 0.71), where higher concentrations were found in central part of the Cunda Strait compared to the southern and northern. Contaminants of heavy metals in S. cucullata, water, and sediment were significantly influenced by temperature, sediment fraction, and organic matter.

Abstract

The Corona Virus Disease (COVID-19) pandemic which has an impact on the economy is no exception to the community around the UNIMAL Faculty of Agriculture. The COVID-19 pandemic condition in Aceh caused UNIMAL to carry out online/online-based lecture activities according to the direction of the Ministry of Education and Culture. Campus activities with an online system cause students to carry out the learning process from their home area so they are not in the environment around UNIMAL. The regulation of the online learning system due to the Corona Virus Disease (COVID-19) Pandemic which dealt a tremendous blow to the economy of the community around the UNIMAL Faculty of Agriculture as traders in the UNIMAL environment and providers of rental houses for students. Then, the lack of knowledge of housewives in East Reulet about what business prospects can be run and the cleanliness and food safety of processed products that need to be realized for public health are the basis for this activity to be carried out. The location of the community service was taken around the UNIMAL Faculty of Agriculture Institution, namely Gampong Reulet Timur, North Aceh Regency. At the preparation stage, the implementation of activities begins with increasing coordination and synergistic cooperation between the parties involved, namely Academic Activists (Lecturers) and the targeted community groups. The implementation methodology is designed for mentors in the form of a participatory approach and refers to the adult learning process (adult-learning), which consists of: (1) Providing information related to sauce processing, (2) assignment or direct practice of sauce processing.
