Akar wangi merupakan tanaman obat yang mengandung minyak atsiri di bagian akarnya. Umumnya tanam akar wangi ditanam di lahan yang subur, namun dalam rangka ekstensifikasi maka perlu dilakukan pemanfaatan lahan marginal untuk tanaman yang potensial dikembangkan antara lain tanah salin. Tanah ini mengandung kadar garam tinggi namun dapat dipergunakan untuk budidaya pertanian melalui penambahan bahan-bahan yang mampu memperbaiki potensi lahan antara lain adalah asam salisilat dan fungi mikoriza arbuskula. Maka perlu dilakukan penelitian tanaman akar wangi di tanah salin yang diberi asam salisilat dan fungi mikoriza arbuskular dengan menggunakan Rancangan Acak Kelompok (RAK) Faktorial dengan 2 faktor, yaitu faktor asam salisilat dengan 4 taraf: A0 = Kontrol, A1 = 50 ppm/plot, A2 = 100 ppm/plot, A3 = 150 ppm/plot dan faktor Fungi mikoriza arbuskular dengan 3 taraf: F0 = Kontrol, F1 = 15 g/polybag, F2 = 30 g/polybag. Hasil penelitian menunjukkan bahwa asam salisilat berpengaruh nyata dan tertinggi pada A3 (150 ppm/plot) untuk panjang akar, berat kering akar, jumlah stomata dan tebal kutikula. Fungi Mikoriza Arbuskular juga berpengaruh nyata dan tertinggi pada perlakuan F2 (30 g/polybag) untuk berat kering akar. Sedangkan interaksi kedua perlakuan tidak memberikan pengaruh yang nyata untuk semua parameter pengamatan.

Kedelai hitam salah satu varietas kedelai yang memiliki kelebihan antara lain kandungan antosianin, isoflavon dan mineral Fe. Namun sekarang ini terjadi penurunan produksi dari tahun ke tahun. Sehingga perlu dilakukan penelitian dalam upaya meningkatkan produksi melalui intensifikasi dengan menggunakan pupuk organik yaitu melalui pemberian limbah biogas cair kelapa sawit dan limbah kulit buah kakao terhadap pertumbuhan dan produksi kedelai hitam (Glycine soja). Penelitian ini bertujuan untuk mengetahui pengaruh limbah biogas cair kelapa sawit dan limbah kulit buah kakao pada kedelai hitam. Penelitian ini dilakukan dengan menggunakan RAK Faktorial, terdiri atas dua faktor yang diteliti: Faktor pertama adalah pemberian limbah biogas cair kelapa sawit (B), yang terdiri dari (B0) Kontrol, (B1) 200 ml/plot + 500 ml air, (B2) 400 ml/plot+500 ml air, (B3)600 ml/plot + 500 ml air. Faktor kedua adalah limbah kulit buah kakao (K), yang terdiri dari(K0)Kontrol, (K1) 250 g/tanaman, (K2) 500 g/tanaman, (K3) 750 g/tanaman dan dilanjutkan dengan uji beda rataan Duncan’s. Pengamatan yang diukur adalahtinggi tanaman, umur berbunga, jumlah cabang, jumlah polong berisi per sampel, jumlah polong hampa per sampel, bobot biji per sampel, bobot biji per plot, bobot 100 biji.Hasil penelitian ini menunjukkan bahwa aplikasi limbah biogas cair kelapa sawittidak berpengaruh pada semua parameter. Aplikasi limbah kulit buah kakao hanya berpengaruh nyata terhadap jumlah cabang dan tertinggi pada dosis 250 g/tanaman (K1). Selanjutnya tidak ada pengaruh interaksi dari pemberian limbah biogas cair kelapa sawit dan limbah kulit buah kakao terhadap semua parameter pengamatan.

Sorgum merupakan salah satu tanaman yang dapat memberikan banyak manfaat diantaranya dari biji menghasilkan tepung sebagai pengganti gandum, dari batang dapat menghasilkan gula dan hijauan pakan ternak. Berdasarkan rata-rata hasil nasional produktivitas sorgum masih rendah yaitu 2,68 ton ha-1 dengan potensi hasil yang seharusnya mencapai 5-7 ton ha-1, maka perlu dilakukan upaya peningkatan hasil. Upaya yang dapat dilakukan adalah melalui penerapan teknologi budidaya dengan menggunakan pemupukan antara lain pupuk kalium dan pupuk organik Palm Oil Mill Effluent (POME). Oleh karena itu perlu dilakukan penelitian yang menggunakan POME dengan 4 taraf yaitu P0 = Tanpa Perlakuan (kontrol), P1 = 200 ml + 800 ml air, P2 = 300 ml + 700 ml air, P3 = 400 ml + 600 ml air dan pemberian kalium dengan 4 taraf yaitu K0 = Tanpa Perlakuan (kontrol), K1 = 10 g/plot, K2 = 20 g/plot, K3 = 30 g/plot. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) faktorial. Data hasil pengamatan dianalisis dengan menggunakan analisis of varians (ANOVA ? = 5%) yang dilanjutkan dengan uji beda rataan menurut Duncan Multiple Range Test (DMRT). Hasil penelitian menunjukan bahwa pemberian POME yang berbeda dosis hanya menunjukkan perbedaan yang nyata pada jumlah daun sedangkan pemberian kalium klorida yang berbeda dosis mempengaruhi secara nyata karakter panjang malai, bobot biji per sampel dan bobot biji per plot. Dari hasil yang diperoleh menunjukkan bahwa ada dosis terbaik perlakuan pupuk kalium klorida yang lebih menunjukkan pengaruh terhadap hasil tanaman sorgum.

Optimal planting date is one of the important factors affecting the wheat crop. Improper planting date can lead to a drastic decrease in wheat yield. Therefore, information about the adaptation of wheat plants at planting date at a particular location will benefit farmers in determining how best to utilize the wheat plants in each production system through morphological characters. Then conducted research The Impact of Differences Planting date against Morphology Character of some Wheat Genotypes in Berastagi of Karo district to determine the most appropriate wheat genotypes grown in Berastagi at certain times growing season through morphological characters. This research was conducted at Berastagi with two planting date (planting date I = late February to early June 2012 and planting date II = late October 2012 to early February 2013), using a Randomized Block Design (RBD) non factorial using 12 wheat plant,namely 2 varieties (Selayar / K and Dewata / L) and 10 genotypes that OASIS / SKAUZ / / 4 * BCN (A); HP1744 (B); LAJ3302 / 2 * MO88 (C); RABE / 2 * MO88 (D), H-21 (E), G-21 (F), G-18 (G); MENEMEN (H); BASRIBEY (I); ALIBEY (J). Observational data were tested with analysis of variance and combined analysis.The observed morphological characters were plant height, number of spikelet spike-1, number of grainspike-1 and grain weight spike-1. The results of analysis of variance and combined analysis showed that all parameters were observed give significantly different results for each planting date.

This paper is a preliminary research in the application of electrosynthesis method in extracting the sample. The maceration process of extraction is one of the simplest ways of extracting nicotine in a preparation. The extraction process can be accelerated by electrochemical principle. The method developed is maceration coupling electrosynthetise in analyzing nicotine contained in cigarette butts. Descriptive method developed in the process of nicotine maseration on filter cigarettes and non-filter cigarettes using ethanol solvents. The experimental method was developed in maceration process and maceration coupling electrosynthesis with variation of time respectively 5, 10, 15, 20, 25 minutes. The best results were obtained on non-filter cigarettes using maceration coupling electrosynthesis at 20 and 25 minutes with qualitative results with cyanogen bromide marked by abundant yellow (+++). The analysis continued using UV-Vis spectrophotometry method and obtained the best sample concentration on non-filter cigarette method of maceration coupling electrosynthesis at 15 minute ( 0,01003 ppm). Keywords: nicotine, filter cigarettes, non-filter cigarettes, electrosynthesis, UV-Vis spectrophotometry
