Abstract

Fungi are one of various types of organisms that play an important role in maintaining balance and preserving nature. Fungi act as decomposers of organic material in forest ecosystems, thus helping to fertilize the soil by providing nutrients for plants. This research aims to determine the types of macroscopic fungi around the Community Forest area, determine the diversity index of macroscopic fungal species and determine the characteristics of the macroscopic fungus habitat around the Community Forest area in Suka Makmur Village, Kutalimbaru District, Deli Serdang Regency, North Sumatra. The method used is field observation and then making a 200 meter transect at the three observation stations, the first station is an oil palm plantation (3°20'33.1''N 98°31^' 34.8''E), a resident's field (3°20'10.9 ''N 98°31^' 00.6''E), and a rubber plantation (3°18'47.9'0'N 98°30^' 58.2''E). In one station, 5 plots were created with a size of 20 x 20 m and the distance between the plots was 25 m. Data analysis using the Shannon-Wiener index. The results are classified in the high category, namely H′ = 3.634. Where at station one, namely oil palm plantations, 27 types of macroscopic fungi were found with a diversity index H'= 2,639 (medium), at the second observation station, namely people's fields, 24 species were found with a diversity index H'= 2,804 (medium) and at station three gardens In rubber, 29 types of macroscopic fungal species were found with a diversity index H′= 3.194 (high). The types of macroscopic fungi found are from two divisions, namely ascomycota and basidiomycota, 7 classes, 11 orders, 28 families and 59 species. Environmental physical factors such as temperature 24 - 26 °C, pH 5.5 - 7.0, and light intensity 290 - 500 candela.

Abstract

Population growth and high consumption patterns have led to increased waste production. This encourages people to look for effective and economically valuable solutions. One potential action that can be taken is to convert organic waste into practical utilization as food for maggot (H. illucens). Maggot (H. illucens) is one of the decomposer organisms that has a fairly high nutritional content. The objective of this study was to evaluate the impact of various feed ingredients, including vegetable waste, rice husk and bran, on the growth rate of larvae (H. illucens). The study was conducted from October to November 2024 in Meurandeh, Langsa Lama, using experimental methodology with a Rancangan Acak Lengkap (RAL) with 6 treatments and 4 repetitions for 21 days. P1: 100% bran, P2: 100% vegetable waste, P3: 100% rice, P4: combination (50% bran + 50% vegetable waste), P5: combination (50% bran + 50% rice), P6: combination (50% bran + 25% vegetable waste + 25% rice. The results showed that treatment A produced the highest absolute biomass of maggots (H. illucens), with an average of 204.25 grams, while treatment B recorded the lowest absolute biomass of maggots (H. illucens), with an average of 157.25 grams. And the highest organic waste composition for maggot length growth (H. illucens) The average length recorded in treatment E was 3.88 cm, while treatment F showed the shortest average length. The Anova results show that different feeding has no significant effect (P>1.112) total weight of biomass maggot (H. illucens), this shows that one of the elements that influence maggot growth is the quality of feed that is rich in protein and normal water content so that it can allow maggot to receive nutrients optimally.

Abstract

Seunuddon, salah satu distrik di Kabupaten Aceh Utara, menjadi salah satu kecamatan yang menjadi titik singgah burung migran. Sebanyak 32 spesies burung migran yang berasal dari beberapa negara teridentifikasi berada di kecamatan tersebut. Akan tetapi, karena kurangnya pemahaman dan edukasi terhadap burung migran, masyarakat lokal mengganggap keberadaan burung migran bukan sesuatu yang istimewa. Hilangnya nilai budaya konservasi dalam masyarakat Aceh mengakibatkan sulitnya upaya untuk melindungi kehadiran burung migran. Rendahnya pemahaman inilah yang menjadi latar belakang perlunya pemahaman nilai konservasi pada SDN 16 Seunuddon, Kabupaten Aceh Utara. Metode kegiatan ini adalah learning by game berupa kegiatan pemaparan materi tentang konservasi dengan menggunakan bahasa Aceh, tanya jawab, kuis interaktif dan lomba mewarnai pada siswa kelas 5 Sekolah Dasar SDN 16 Seunuddon. Dari hasil kegiatan didapatkan peningkatan pemahaman siswa mengenai burung migran dan konservasi wilayah pesisir. Berdasarkan hasil wawancara anak-anak lebih paham dengan menggunakan bahasa Aceh karena merupakan bahasa sehari-hari. Terdapat kenaikan yang cukup signifikan dari hasil kuis yang telah dilakukan yaitu nilai rata-rata pre-test yaitu 49,2 dan mengalami kenaikan pada nilai post-test sebesar 84,6. Untuk pemahaman siswa melalui tebak gambar, siswa mampu menjawab nama burung migran dari gambar yang disajikan. Sementara itu, untuk lomba mewarnai, 25 siswa mampu mewarnai gambar dengan objek burung migran dengan kategori baik dan 10 dengan kategori sangat baik.

Abstract

Populasi bangau tongtong terus menurun akibat perusakan habitat, perburuan liar, dan gangguan manusia. Oleh karena itu, upaya konservasi bangau tongtong menjadi penting, baik melalui pendekatan in situ maupun ex situ. Kawasan konservasi ex situ seperti taman hutan kota Langsa menjadi salah satu model untuk menjaga kelangsungan hidup spesies ini. Penelitian ini bertujuan untuk menganalisis distribusi waktu yang dihabiskan bangau tongtong untuk berbagai aktivitas di lingkungan konservasi buatan. Setiap individu diamati selama 900 menit, sehingga total akumulasi waktu pengamatan untuk empat individu mencapai 3600 menit dengan menggunakan metode scan animal sampling. Hasil penelitian menunjukkan bahwa aktivitas istirahat memiliki frekuensi paling tinggi, dengan total waktu selama 1871,72 menit, diikuti oleh aktivitas ingesti (656,09 menit), preening (618,69 menit), dan lokomosi (442,5 menit). Sementara itu, aktivitas interaksi sosial dan ekskresi memiliki frekuensi yang sangat rendah, masing-masing hanya tercatat selama 7,57 menit dan 3,43 menit. Analisis lebih lanjut terhadap tingkat dominansi perilaku pada setiap periode waktu menunjukkan bahwa perilaku diam berdiri paling mendominasi di semua periode, yaitu pagi (26,27%), siang (38,64%), dan sore (49,02%). Perilaku lainnya seperti makan, berjalan, menelisik bulu, dan bertengger juga muncul dengan proporsi yang bervariasi sesuai waktu pengamatan. Penelitian ini menunjukkan bahwa bangau tongtong telah mengalokasikan sebagian besar waktunya untuk istirahat pasif. Temuan ini mencerminkan adaptasi terhadap lingkungan konservasi yang minim rangsangan dan menjadi dasar peningkatan kesejahteraan satwa serta efektivitas konservasi jangka panjang.

Abstract

In seed cultivation business, feeding seeds is a critical component towards successful cultivation. The problems faced at this time are the low level of technology and knowledge possessed by farmers, both types of feed, supplementary feeding and water management, so that the growth rate and survival rate obtained in milkfish cultivation are still very low. For this reason, accurate information and training is needed regarding milkfish hatchery technology as a reference that can be used by milkfish farmers. Based on the problems faced by the Joint Business Fisheries Group partners and the results of the agreement between the University of Samudra Community Service Team and partners, solutions were obtained (1) socialization of the importance of natural fish feed, namely rotifers for the survival of milkfish, (2) training in culture techniques Rotifers (Brachionus plicatilis) as natural food for milkfish, (3) making ponds/ aeration tanks for culture Rotifers (Brachionus plicatilis) as natural food for milkfish. The method of implementing the activities includes four main stages, namely field surveys, socialization, training, and assistance to monitor and evaluate the progress of the results of activities for the sustainability of the program in the village. Activities that have been carried out include four main stages, namely field surveys, socialization of activities, training on natural food culture, rearing and harvesting of fish that will be carried out at the end of August, and assistance to monitor and evaluate the progress of the results of activities for the sustainability of the program in the Gampong Baroh Bugeng. So that there has been an increase in knowledge and skills about the importance of natural food in the form of Brachionus plicatilis in milkfish cultivation so that currently milkfish farmers increase milkfish yields, increase the quality and quantity of live seeds so they can increase milkfish production and yields and create ponds. Rotifera (Brachionus plicatilis) culture aeration tub as natural fish food.
