Penelitian ini bertujuan untuk mengevaluasi respon pertumbuhan dan produksi rosella (hibiscus sabdariffa L.) pada tanah salin dengan pemberian asam salisilat dan giberellin (GA3). Penelitian ini dilakukan di rumah kaca, Fakultas Pertanian, Universitas Sumatera Utara, Medan, pada Februari 2014 sampai Juni 2014. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 3 (tiga) factor dan 3 (tiga) ulangan. Faktor pertama giberellin (GA3) dengan dua taraf yaitu 0 mg L-1, 5 mg L-1. Faktor kedua asam salisilat dengan tiga taraf yaitu 0 mM, 0,5mM, 1 mM. Faktor ketiga tingkat salinitas dengan 2 taraf yaitu 0 dsm-1 dan 4-5 dsm-1. Hasil penelitian menunjukkan bahwa interaksi antara giberellin dan cekaman salinitas memperlihatkan pengaruh nyata pada peubah pertumbuhan seperti persentase perkecambahan, tebal kutikula dan betakaroten. Interaksi antara perlakuan asam salisilat dan cekaman salinitas memperlihatkan pengaruh nyata pada tebal kutikula dan betakaroten. Interaksi tiga factor perlakuan giberellin, asam salisilat dan cekaman salinitas menunjukkan pengaruh yang nyata pada peubah tebal kutikula dan betakaroten.

Konservasi sumber daya tanah adalah perlindungan sumber daya alam tanah. Hal ini dicapai dengan menghilangkan atau mengurangi dampak manusia terhadap lingkungan alam, pemanenan sumber daya lahan yang bertanggung jawab, serta upaya konservasi yang bertujuan untuk membalikkan kerusakan manusia terhadap sumber daya lahan. Konservasi dan pelestarian lingkungan menawarkan dua pendekatan tentang bagaimana mengelola lahan publik secara bertanggung jawab. Pengabdian Masyarakat ini bertujuan untuk melakukan penanaman akar wangi (Vetiveria zizanioides) di taman edukasi dan konservasi sumber daya lahan Lembah Juhar, Kabupaten Langkat, Sumatera Utara. Kegiatan pengabdian masyarakat yang dilakukan berupa penanaman 200 bibit tanaman akar wangi yang dilakukan di taman edukasi dan konservasi sumber daya lahan Lembah Juhar, Kabupaten Langkat bersama dengan beberapa praktisi dan akademisi dari berbagai institusi di daerah Sumatera Utara dalam rangka Hari Air Sedunia, selain itu pengabdian masyarakat ini juga memberikan sosialisasi mengenai tanaman akar wangi kepada masyarakat sekitar lahan Lembah Juhar, Kabupaten Langkat mengenai pentingnya konservasi dan pelestarian lingkungan yang sekaligus dapat memberikan manfaat kepada masyarakat sebagai taman edukasi.

The research was carried out from June to completion, at the Deli Tobacco Research Institute (BPTD) Sampali PTPN II. This study aims to determine the effect of KCl fertilizer and goat urine on the growth and yield of Japanese cucumbers. This study used a factorial randomized block design (RAK) with 2 factors. The first factor is KCl with 4 levels, namely S0 (Control), S1 (10 g/plant), S2 (20 g/plant), S3 (30 g/plant) the second factor is Goat Urine with 4 levels, namely K0 (Control), K1 (200 ml/plant), K2 (400 ml/plant) and K3 (600 ml/plant). Parameters measured were vine length, leaf number, leaf area, number of fruit per plant, fruit length, number of fruit per plot, fruit weight per plant and fruit weight per plot. The results showed that KCl fertilizer had an effect on the number of fruits per plant and the number of fruits per plot but the administration of goat urine had no effect on all parameters. The interaction of KCl fertilizer and goat urine did not affect all parameters.

Jurnal Natural Volume 22 Number 3, October 2022
Publisher : Universitas Syiah Kuala

Root induction is an important step in plant propagation in vitro. Root stimulation can occur in the presence of the hormones auxin and gibberellins which can be obtained from other plants, one of which is bananas. The research aims to determine the effect of various species and concentrations of the banana extract on Phalaenopsis amabilis root induction in vitro. The research was conducted in the Laboratory of Tissue Culture Alifa Agricultural Research Center (AARC), Medan, North Sumatera, from May until July 2020. The research used a Factorial Completely Randomized Design (CRD) with 2 factors, the first factor was the type of banana extract with 3 levels, consisting of Ambon, Raja, and Kepok. The second factor is the concentration of banana extract (C) with 4 levels, consisting of 50 g/l, 100 g/l, 150 g/l, 200 g/l. The results showed that the concentration of banana extract had a significant effect on the number of roots, but various species of bananas and the interaction of the species of bananas and concentration banana extract had no significant effect on root induction

Vetiver root is a commodity that is tolerant enough to be planted in salty soils with a certain level of salinity. One approach to increase oxidative stress tolerance that will increase the enzyme substrate at the cellular level is ascorbic acid. The purpose of this study was to increase students' knowledge about how the response of vetiver seed (Vetiveria zizanioides) growth in salt soils to ascorbic acid through practical field learning in plant physiology courses. This research was conducted using a factorial randomized block design (RBD), the first factor was the salinity (S), namely S0: 0 dsm-1 and S1: 4 dsm-1. The second factor was ascorbic acid (A), namely A0: without treatment, A1: 50 ppm, A2: 100 ppm and A3: 150 ppm. There were 8 treatment combinations that were repeated 3 times resulting in 24 experimental units. The parameters observed were plant height, number of leaves and number of stomata. In this study, ascorbic acid had a significant effect on plant height, number of leaves and number of stomata. Saline soil had a significant effect on the number of stomata parameters. No interactions for all parameters were observed.

Deficiency or excess magnesium in the soil can affect the vegetative and generative growth of plants. This study aimed to identify the effect of magnesium deficiency and toxicity on the agronomic and physiological characteristics of upland rice. The study was conducted on farmers' land, Medan Selayang Subdistrict, Medan City, from June 2021 to January 2022. This study used a non-factorial randomized block design, namely the application of 27% MgO fertilizer based on the deficiency rates, (0; 1/2; 1/4; 1/8; 1/16; 1/32 times), while the toxicity levels include 0; 2; 4; 8; 16; 32-times within three replicates. The results showed that Mg deficiency significantly inhibited the growth of plant height; leaf area; total chlorophyll SPAD; panicle length; shoot dry weight; and yield.ha-1 were 20.68; 26.77; 19.23; 22.60; 44.20; and 50.72%, respectively. The Mg toxicity significantly inhibited the growth of the leaf area, the number of tillers, number of productive tillers, shoot dry weight, and root dry weight were 14.24; 32.15; 42.87; 34.07; and 44.31%, respectively. The critical limit (BK50) for upland rice caused by deficiency and toxicity of Mg were 0.032 and 1125.189 g/10 kg of the soil, respectively.

Teknik perbanyakan kopi secara vegetatif dengan cara setek memiliki beberapa keunggulan yaitu menghasilkan tanaman baru dalam jumlah banyak dengan waktu relatif singkat dan biaya operasional yang relatif murah. Namun kelemahan dari teknik perbanyakan ini adalah tingkat keberhasilannya yang lebih rendah dibandingkan teknik lain. Penelitian ini bertujuan untuk mengkaji pengaruh interaksi antara perbedaan konsentrasi Zat Pengatur Tumbuh (ZPT) air kelapa dan ekstrak bawang merah terhadap respon pertumbuhan setek kopi robusta yang berasal dari pucuk (S1) dan ruas pertama setelah pucuk (S2). Penelitian ini dilakukan di laboratorium lapangan perkebunan Politeknik Pembangunan Pertanian Medan menggunakan rancangan acak kelompok pola faktorial. Faktor pertama adalah pucuk pertama dan ruas pertama setelah pucuk, faktor kedua adalah konsentrasi ZPT 50% dan 75% serta kombinasi ZPT air kelapa dan ekstrak bawang merah dengan 5 ulangan. Variabel yang diamati meliputi jumlah tunas, jumlah daun, diameter daun, panjang akar dan jumlah akar. Data yang diperoleh dianalisis dengan ANOVA (Analysis of variance) dan dilanjutkan dengan uji Duncan taraf 5%. Hasil penelitian menunjukkan pemberian konsentrasi ZPT bawang merah 50%. dapat meningkatkan jumlah tunas, jumlah daun, diameter daun, panjang akar dan jumlah akar. Pemberian konsentrasi ZPT bawang merah 50%. y juga memberikan pengaruh terhadap keberhasilan pembibitan. Persentase setek berakar meningkat pada perlakuan pucuk dibandingkan ruas pertama setelah pucuk dengan perlakuan ZPT bawang merah 50%.
