Abstract

Abstrak. Tujuan dari penelitian ini untuk mengetahui pengaruh jenis media tanam dan konsentrasi air kelapa muda, serta ada tidaknya interaksi keduanya terhadap pertumbuhan setek tanaman tin. Penelitian ini dilakukan dari bulan April hingga Juli 2019, di Rumah Kasa dan Laboratorium Fisiologi Tumbuhan Fakultas Pertanian. Rancangan penelitian yang digunakan ialah RAK pola faktorial 4 x 4 dengan 3 ulangan. Faktor yang diteliti ialah jenis media tanam terdiri 4 taraf (tanah + kompos, tanah + pupuk kandang, tanah + arang sekam, dan tanah + sekam padi) dan konsentrasi air kelapa muda terdiri 4 taraf (0%, 25%, 50% dan 75%). Hasil penelitian menunjukkan bahwa jenis media tanam berpengaruh terhadap panjang tunas, jumlah daun 30, 60 dan 90 HST, jumlah tunas 60 dan 90 HST, berat brangkasan kering, panjang akar, berat brangkasan basah, berat kering akar dan berat basah akar. Pertumbuhan setek tanaman tin terbaik dijumpai pada jenis media tanam tanah + kompos (1:1). Konsentrasi air kelapa muda berpengaruh terhadap jumlah daun, panjang tunas 30 HST, jumlah tunas 90 HST, berat brangkasan kering, panjang akar, berat brangkasan basah, berat kering akar dan berat basah akar. Pertumbuhan setek tanaman tin terbaik dijumpai pada konsentrasi air kelapa muda 75%. Terdapat interaksi antara jenis media tanam dan konsentrasi air kelapa muda terhadap jumlah tunas 60 dan 90 HST, panjang tunas 30, 60 dan 90 HST, jumlah daun 30 HST, berat brangkasan basah, berat brangkasan kering, panjang akar, berat basah akar dan berat kering akar. Pertumbuhan setek tanaman tin terbaik dijumpai pada kombinasi antara jenis media tanam tanah + kompos (1:1) dengan konsentrasi air kelapa muda 75%.The Effects of Types of Planting Media and Concentration of Green Coconut Water on the Growth of Cuttings of Fig Plants (Ficus carica L.)Abstract. The purpose of this study to determine the effects of the types of planting media and the concentration of green coconut water, as well as the interaction between the two on the growth of the cuttings of fig plants. This research was conducted at the Greenhouse and Plant Physiology Laboratory of the Faculty of Agriculture of Syiah Kuala University from April to July, 2019. The research design used was a randomized block design with the 4 x 4 factorial pattern and three replications. The factors studied were the planting media consisting of 4 different types, namely soil mixed with compost, soil mixed with manure, soil mixed with rice husk charcoal, and soil mixed with rice husk and the green coconut water concentration consisting of four levels, namely 0%, 25%, 50% and 75%. The results indicates that the treatment given to the planting media gave a significant effect on the length of the buds, the number of leaves in 30, 60 and 90 DAP, the number of buds in 60 and 90 DAP, the dry strover weight, the root length, the wet strover weight, the dry root weight and the wet root weight. Furthermore, it significantly affected the length of the buds in 30 DAP. The best growth of cuttings of fig plants is found in the type of soil mixed with compost (1: 1). The results also shows that the concentration of green coconut water also had a very significant effect on the number of leaves, length of the buds in 30 DAP, the number of buds in 90 DAP, the dry strover weight, the root length, the wet strover weight, the dry root weight, and the wet root weight. The best growth of cuttings of fig plants is found in concentration of green coconut water 75%. There was also an interaction found between the types of planting media and the concentration of green coconut water which had a very significant effect on the number of buds in 60 and 90 DAP, the length of the buds in 30, 60 and 90 DAP, the number of leaves in 30 DAP, the wet strover weight, the dry strover weight, the root length, the wet root weight and the dry root weight. The best growth of cuttings of fig plants is found in the combination of type of soil mixed with compost with concentration of green coconut water 75%.

Abstract

Abstrak. Penghambatan yang disebabkan oleh gulma bisa mengganggu pertumbuhan serta perkembangan tanaman budidaya. Aplikasi herbisida kimia sintetik dalam waktu berkepanjangan cenderung menimbulkan efek negatif, sehingga perlu dicari cara yang aman bagi lingkungan dengan memanfaatkan senyawa turunan tumbuhan (alelokimia) sebagai bioherbisida. Babadotan adalah tanaman yang berpotensi sebagai bioherbisida. Penelitian ini memiliki tujuan guna mengetahui aktivitas ekstrak etil asetat babadotan subfraksi A pada berbagai konsentrasi terhadap pertumbuhan gulma bayam duri. Penelitian ini dilaksanakan di Labratorium Ilmu Gulma Fakultas Pertanian, Laboratorium Herbarium Jurusan Biologi Fakultas Matematika dan Ilmu Pengetahuan Alam, Laboratoium Analisis Kimia Fakultas Keguruan dan Ilmu Pendidikan, Laboratorium Kimia Organik Fakultas Matematika dan Ilmu Pengetahuan Alam, Laboratorium Analisis Pangan dan Hasil Pertanian Fakultas Pertanian dan Kebun Percobaan Fakultas Pertanian Universitas Syiah Kuala, dari Januari hingga Juli 2022. Rancangan penelitian yang dipakai adalah Rancangan Acak Lengkap (RAL) non faktorial, terdapat 7 perlakuan yaitu konsentrasi ekstrak etil asetat babadotan subfraksi A 2%, 4%, 6%, 8%, 10%, kontrol positif (2,4-D) dan kontrol negatif (aquades) dengan 3 kali ulangan, hingga didapatkan 21 satuan percobaan. Hasil penelitian membuktikan aplikasi ekstrak etil asetat babadotan subfraksi A pada konsentrasi 4%, 6%, 8% dan 10% dapat menghambat pertumbuhan tinggi gulma, jumlah daun dan diameter batang gulma bayam duri dan sama pengaruhnya dengan kontrol positif (2,4-D).Activity of  Ethyl Acetate Extract Billygoat (Ageratum conyzoides L.) Subfraction A at Various Consentration on Spiny Amaranth (Amaranthus spinosus L.)Abstract. Inhibition caused by weeds can interfere with the growt and development of cultivated plants. The application of synthetic chemical herbicides for a long time tends to cause negative effects, so it is necessary to find environment by utilizing plant-derived compounds (alelochemicals) as bioherbicides. Billygoat is a plant that has the potential as a bioherbicides. This study aimed to decide the activity of ethyl acetate extract of billygoat weed subfraction A at various concentrations on spiny amaranth growth. This research was conducted at the Weed Science Laboratory, Faculty of Agriculture, Herbarium Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Laboratory of Chemical Analysis, Faculty of Teacher Training and Education, Laboratory of Organic Chemistry, Faculty of Mathematics and Natural Sciences, Laboratory of Food and Agricultural Product Analysis, Faculty of Agriculture and garden experimental Faculty of Agriculture, Syiah Kuala University, from January to July 2022. The research design used was a non-factorial Completely Randomized Design (CRD), there were 7 treatments namely of a concentration of ethyl acetate extract of billygoat subfraction A 2%, 4%, 6%, 8%, 10%, positive control (2,4-D) and negative control (aquades) with 3 replications, until there are 21 trial units. The results of the study proved the application of ethyl acetate extract of billygoat subfraction A at concentrations of 4%, 6%, 8% and 10% could inhibit the growth of weed height, leaf number and stem diameter on spiny amaranth thorn weed and as well as positive control (2,4-D).
