Penelitian ini bertujuan untuk mendapatkan konsentrasi pupuk organik cair urine kambing yang tepat terhadap pertumbuhan dan produksi tanaman jagung manis. Rancangan percobaan yang digunakan dalam penelitian ini adalah rancangan acak kelompok (RAK) non faktorial yang teridiri dari 5 perlakuan yaitu P0 = 0 %, P1= 5 %, P2= 10 %, P3= 15 % dan P4= 20 %. Parameter yang diamati adalah tinggi tanaman (cm), diameter batang (mm), jumlah daun (helai), bobot tongkol berkelobot per plot (g), bobot tongkol berkelobot per tanaman (g), bobot tongkol tanpa kelobot (g), diameter tongkol (g), persentase panjang tongkol berisi (%) dan produksi tongkol berkelobot per hektar (ton). Dari hasil yang telah didapat, diketahui bahwa pemberian berbagai konsentrasi pupuk organik cair urine kambing berpengaruh nyata meningkatkan tinggi tanaman (cm), diameter batang (mm), bobot tongkol berkelobot per plot (g), bobot tongkol berkelobot per tanaman (g), bobot tongkol tanpa kelobot (g), diameter tongkol (mm) dan produksi tongkol berkelobot per hektar (ton). Pemberian berbagai konsentrasi pupuk organik cair urine kambing berpengaruh tidak nyata terhadap jumlah daun (helai) dan persentase panjang tongkol berisi (%). Hasil terbaik untuk meningkatkan pertumbuhan dan produksi tanaman jagung manis adalah pada perlakuan P3 yaitu pada konsentrasi 15 % pupuk organik cair urine kambing.
<p class="8AbstrakBahasaIndonesia">Penelitian Budidaya Tanaman Sawi (<em>Brassica Juncea L.</em>) Pada Media Tanam Yang Berbeda Secara Vertikultur. Tujuan penelitian untuk mengetahui teknik budidaya tanaman Sawi yang lebih efisien dengan menggunakan media tanam yang berbeda secara vertikultu. Penelitian dilakukan di kebun percobaan Fakultas Pertanian Universitas Medan Area yang berlokasi di jalan Kolam No. 1 Medan Estate, Kecamatan Percut Sei Tuan dengan ketinggian tempat 25 m dari permukaan laut, topografi datar dan jenis tanah alluvial. Penelitian ini dilaksanakan Mei 2014 / Juli 2014, penelitian mengunakan rancangan acak kelompok faktorial yang terdiri dari 2 faktor perlakuan, yaitu Faktor pertama Pola Budidaya (P) yang terdiri dari 3 taraf, P1 = Konvensional P2 = Vertikultur bambu P3 = Vertikultur botol plastik bekas. Faktor kedua Media tanam (M) yang terdiri dari 2 taraf : M1 = tanah + pupuk kandang sapi dan M2 = tanah + pupuk kompos sayuran. Hasil penelitian menunjukan bahwa pemberian pupuk kandang sapi dan kompos sayur tidak menunjukan perbedaan yang nyata terhadap pertumbuhan tanaman sawi, tetapi pola tanam menunjukan pengaruh yata pada pertumbuhan tanaman sawi hijau (P1) konvesional dan disusul dengan pelakuan perikultur yang tidak jauh berbeda yaitu P2 (verikultur dengan Bambu). Secara umum penelitian tidak menunjukan hasil yang berbeda nyata tetapi pengunaan pola tanam verikultur dengan bambu dapat digunakan karea hasil tidak jauh berbeda dengan konvensional.</p>
A standard learning material can be designed as a learning media to facilitate the students with complete information from the appropriate sources and can be accessed anytime and be able to facilitate students to learn independently. This study aimed to provide a multimedia Lectora Inspire integrated Problem Based Learning (PBL) on carbohydrate topic to be used as a learning media in the teaching and learning activities for students of Department Agrotechnology at Universitas Medan Area in academic year of 2018/2019. This study of research is Research and Development method that uses ADDIE. The samples were totally selected and divided into two groups. Development of multimedia Lectora Inspire integrated PBL in experimental class I while the learning media that used in Department of Agrotechnology used in experimental class II. Data were analyzed using descriptive method and statistical analysis with independent sample t-test. The experimental class has fulfilled the requirement for normality and homogeneity test. The results showed that: (1) the learning media used in Department of Agrotechnology on carbohydrate topic is eligible to use but needs to be developed; (2) multimedia that has been developed by using Lectora Inspire integrated PBL on carbohydrate topic is very eligible to be used as a learning media in accordance with the standart of SNPT eligibility (3.75), the eligibility of interactive computer media (3.48), and the eligibility of PBL (3.38); (3) students achievement in experimental class I was found to be higher than in the experimental class II (0,74 > 0,64).
The purpose of this study was to obtain data on the ability of cabbage compost (Brassicaceae) and banana weevil liquid organic fertilizer on the growth and production of long bean plants (Vigna Sinensis L.). The method used in this study is a randomized block design (RBD) in factorial, with 2 (two) treatment factors, Namely: 1) Factors Cabbage Compost Fertilizer (K); 2) Faktors liquid organic fertilizer banana weevil (P), each treatment was repeated two (2) times so that there are 32 experimental plots. Each experimental plot consisted of 9 plants with 4 plant samples. The parameters were observed in this study consisted of stem diameter, number of pods per sample plant, pod length per sample plant, pod weight per sample plant, production per plot; From the research has been carried out can be concluded as follows: 1) Provision of POC banana weevil has no real effect on stem diameter, number of pods per sample plant, pod length per sample plant, pod weight per sample plant, production per plot; 2) The administration of cabbage compost has a significant effect on stem diameter, number of pods per sample plant and production per plot, but has no real effect on pod length per sample plant and pod weight per sample plant; 3) The combination of the two treatment factors has no real effect on stem diameter, number of pods per sample plant, pod length per sample plant, pod weight per sample plant, production per plot
Oyster mushroom is one of the most popular consumed mushrooms and also gives benefit for the body because it contains high nutrition and low fat. The goal of this research was to know and analyse the increase growth of some varieties of oyster mushroom on the bagasse media by adding molasses and tofu dregs. The research method was completely factorial randomized design (RAL Factorial) with two factors. The first factor was the media composition of sawdust and bagasse powder and The second factor was oyster musroom. The data analysis was tested by Anova and continued with duncan test if the results of variance were significantly different to very real. The results showed that the best treatment for mycelium growth on M1 media (100% bagasse + 1% molasses + 6% tofu dregs) with the best combination M2V3 (75% bagasse + 25% sawdust + 1% molasses + tofu dregs 6% on brown oyster mushroom). The largest stem diameter for V1 (white oyster mushroom) was 9.24 cm at the first harvest, and 9.01 cm the second harvest. The best length of the stalk in V3 variety (brown oyster mushroom) was 4.94 cm at the first harvest and 5.11 cm the second harvest. The best treatment on oyster mushroom production showed that variety V1 (white oyster mushroom) showed high production at the first harvest 130.25 grams and the second harvest 132.83 grams.
