Abstract

AbstractOryctes rhinoceros L. has symbioses with micro organisms in their hind guts which further break down plant material consumed by beetle. The aim of this research is to determine the identification of the existence of the bacterial species in the hind gut larvae of the symbiotic bacteria using biochemical test and analysis based on 16S rRNA. The result of this research indicate that there were two different bacterials: Bacillus siamensis and Bacillus stratosphericus found. The bacteria was used for starting the composting and more specifically, the Bacillus siamensis can speed up composting with the end result at C/N 13.16.Keywords: Larvae O. rhinoceros L, Bacterial Symbionts, 16S rDNA, Composting

Abstract

Pertumbuhan dan pembibitan tanaman kelapa sawit dilakukan melalui penggunaan Jamur Trcihoderma,Top soil, pasir dan pupuk kandang sebagai media tanam, jenis pupuk kandang yang digunakan yaitu pupuk kandang dari kotoran lembu. Tujuan dari penelitian adalah untuk mengetahui pengaruh dari pemberian Jamur Trichoderma, pemberian Pupuk NPK dan juga pemberian Jamur Trichoderma dibarengi dengan pemberian pupuk NPK sekaligus. Pemberian jamur Trichoderma dan pemberian pupuk NPK dengan dosis yang berbeda bertujuan untuk mengetahui dosis yang tepat pada tanaman kelapa sawit, lalu melihat interaksi kedua perlakuan pada fase pembibitan tanaman kelapa sawit. Penelitian ini dilakukan di Kecamatan Selesai Kabupaten Langkat Sumatera Utara pada bulan Juni 2022 sampai dengan Desember 2022. Rancangan penelitian adalah Rancangan Acak Kelompok (RAK) Faktorial dengan faktor pertama pertama Pupuk Kimia (N) yang terdiri dari 2 taraf perlakuan yaitu: N1 = NPK (4gr/batang) K2 = NPK (6 gr/batang) Factor kedua pemberian Jamur Trichoderma dengan simbol (J) yang terdiri dari 3 taraf perlakuan yaitu J0= 0 Kontrol (tanpa perlakuan) J1= 20ml/batang J2 = 30ml/batang. Parameter yang diamati dalam penelitian ini adalah tinggi batang (cm), Panjang daun (cm). Pada penelitian dengan Rancangan Acak Kelompok (RAK) Faktorial menunjukkan bahwa Hasil dari  perlakuan NPK berpengaruh sangat nyata terhadap tinggi tanaman, diameter batang, dan terhadap panjang daun, serta berpengaruh tidak nyata terhadap jumlah daun. Sedangkan perlakuan jamur Trichoderma menunjukkan bahwa perlakuan Trichoderma berpengaruh sangat nyata terhadap panjang daun, dan berpengaruh tidak nyata terhadap tinggi tanaman, diameter batang, dan jumlah daun. Sementara hasil penelitian dari interaksi perlakuan NPK dan Trichoderma berpengaruh nyata terhadap panjang daun, dan berpengaruh tidak nyata terhadap tinggi tanaman, diameter batang, dan jumlah daun. Kata Kunci : Jamur Trichoderma, Pupuk NPK, Kelapa Sawit

Abstract

Indonesia, as a tropical country, faces significant challenges in preserving its mangrove forests, particularly in the Beras Basah Ecotourism Area, Langkat Regency, which holds high ecological and economic potential. The food estate in mangrove forests aims to develop land for food production, specifically as a source of forage for stingless bees. This community service project aims to preserve the food estate through tree planting in the Beras Basah Ecotourism Area. The methodology includes interviews and discussions, involving 22 participants from Universitas Tjut Nyak Dhien, Tottori University Japan, and Universitas Sumatra Utara. The project results indicate a decline in the stingless bee population due to limited food sources from the mangrove area. Planting fruit trees such as water guava, stone guava, and mango is expected to provide ecological benefits, attract tourists, and support the development of a food estate for stingless bees. With a sustainable approach, this food estate program can serve as a model for the development of mangrove forests as ecotourism areas and strengthen food security in the Beras Basah village, Langkat, North Sumatra. Keywords : Ecotourism; food estate; mangrove; stingless bees
