Abstract

This study was intended to analyze and see factors that influence the production of salak pondoh in Tiga Juhar Village, with various production theories and using several variables as a measurement tool in this study consisted of land area, labor, fertilizer, seeds and capital. The data used in this study were primary data that was obtained by distributing a list of questions that have been prepared by interviewing farmers directly. Sampling criteria with judgment sampling method (purposive sampling) is the technique of determining the sample of research on several characteristics of the members adjusted to the purpose of the researcher. The researcher choosen the sample to fulfill the goal by ensuring that all the pepulations had certain characteristics, with the consideration that some research samples were homogeneous or on average have a land area. The samples in this study were 70 farmers from the total number of salak pondoh farmers (243 people) in Tiga Juhar village. Data analysis method used in this study, was multiple linear regression analysis method, this method was used to predict the influence of a dependent variable based on independent variables using the SPSS 2017 software application tool. The results showed that (1) the estimated estimated salak pondoh production model gave positive results because all the observed independent variables showed that the variables of Land Area, Labor, Fertilizer, Seedlings and Capital had a significant effect on the production of salak pondoh in Tiga Juhar Village. (2) Analysis of estimation data showed a significant influence of dependent variables with independent variables. This can be seen from the R-Squared test of 0.963 which means that free variation (land area, labor, fertilizer, seeds and capital) had significant effect on salak production by 96 percent and the remaining 4 percent by other variables not found in the estimation model. While the F test was 331,529 or the probability value of 0.0000 had a significant effect on the production of salak pondoh at a 95% confidence level.

Abstract

Shallots (Allium ascalonicum L) are included in the superior national product. In increasing the production of shallots, fertilizers containing complete nutrients are needed from various agricultural wastes which are fermented anaerobically to obtain solid and liquid organic fertilizers. This research method uses a factorial Randomized Block Design (RAK) consisting of 2 factors studied with 16 treatment combinations and 2 replications. Factor I solid organic fertilizer (P) with a level of 0 kg/plot, 1.5 kg/plot, 2.5 kg/plot, 3.5 kg/plot, and factor 2 liquid organic fertilizer (C) with a level of 0 ml/liter water/plot, 250 ml/liter of water/plot, 450 ml/liter of water/plot, 650 ml/liter of water/plot. Parameters observed were plant height (cm), wet tuber weight (g), dry tuber weight (g), and production conversion per hectare (kg). The results of the study of the 4 parameters gave a significant effect on the 2 treatments. This is what the researcher hopes for and it is recommended that further research be carried out by providing a higher level of treatment for this research. Keywords: fertilizer. solid, liquid, shallot, red.

Abstract

Shallots (Allium ascalonicum) Var. Sanren F1 is one of the vegetable commodities that has become a national flagship in addition to red chili and potatoes. Shallots are a strategic commodity because they are needed by most Indonesians in their daily lives. This research was carried out in Minta Kasih Village, salapian District, Langkat Regency, North Sumatra Province with an altitude of + 50 meters above sea level, with the aim of research to determine the effect of the use of organic liquid fertilizer in increasing the growth and production of shallots of the Sanren F1 variety. The study used a Non-Factor Group Randomized Design (RAK) consisting of 4 treatment levels (C0= 0 ml/liter water/m2, C1=225 ml/liter water/m2, C2=425 ml/liter water/m2, C3=625 ml/liter water/m2) with 3 repeats, so that there were 12 experimental units consisting of 8 sample plants, so that the total observation of the entire plant there were 96 experimental units with parameters consisting of plant height,  number of leaves, production of wet tubers, production of dry tubers, conversion of production per hectare. The role of organic liquid fertilizer has a very real effect on plant height, number of leaves, number of tubers, dry tubers production and conversion of production per hectare with the best treatment at C3. C3 treatment can be improved again in further research to obtain maximum growth and production in shallots. Key-words: Liquid Fertilizer, Shallot, Organic INTISARI Bawang merah (Allium ascalonicum) Var. sanren F1 merupakan salah satu komoditi sayuran yang menjadi unggulan nasional selain cabai merah dan kentang. Bawang  merah merupakan komoditas strategis karena dibutuhkan sebagian besar masyarakat Indonesia dalam kehidupan sehari-hari. Penelitian ini dilaksanakan di Desa Minta kasih Kecamatan Salapian Kabupaten Langkat Provinsi Sumatera Utara dengan ketinggian tempat + 50 meter diatas permukaan laut, dengan tujuan penelitian untuk mengetahui pengaruh penggunaan pupuk cair organik dalam meningkatkan pertumbuhan dan produksi bawang merah varietas Sanren F1. Penelitian menggunakan Rancangan Acak kelompok (RAK) Non Faktor terdiri dari 4 taraf perlakuan (C0= 0 ml/liter air/m2, C1=225 ml/liter air/m2, C2=425 ml/liter air/m2, C3=625 ml/liter air/m2) dengan 3 ulangan, sehingga terdapat 12 satuan percobaan yang terdiri dari 8 tanaman sampel, sehingga total pengamatan keseluruhan tanaman ada 96 unit percobaan dengan parameter terdiri dari tinggi tanaman, jumlah daun, jumlah umbi, produksi umbi kering, konversi produksi per hektar. Peranan pupuk cair organik berpengaruh sangat nyata pada tinggi tanaman, jumlah daun, Jumlah Umbi, produksi umbi kering dan konversi produksi perhektar dengan perlakuan terbaik pada C3. Perlakuan C3 dapat ditingkatkan lagi pada penelitian lanjutan untuk mendapatkan pertumbuhan dan produksi maksimal pada bawang merah. Kata kunci : Pupuk Cair, Bawang Merah, Organik

Abstract

Budidaya kakao diindonesia umumnya petani masih menggunakan teknik tradisional,  Hal tersebut juga diiringi minimnya inovasi dan teknologi pada budidaya kakao sehingga banyak sekali pohon kakao kurang terawat dengan baik. Permasalahan budidaya kakao biasanya karena kurangnya pemanfaatan teknologi produksi kakao tidak optimal dan penggunaan bahan tanam yang tidak jelas asalnya, Petani juga kurang melakukan pemupukan yang sesuai aturan, dan kurang dalam perawatan, sehingga serangan organisme pengganggu tanaman meningkat Penggunaan pupuk kimia tidak sesuai dengan anjuran, mengakibatkan kualitas dan kesuburan tanah menurun. Solusi untuk mengurangi pemakaian pupuk anorganik adalah memanfaatkan bahan organik yang berasal dari tanah akar bambu dan mikroorganisme sebagai pupuk hayati. Bakteri akan meningkatkan mekanisme pertumbuhan biomassa akar. Isolat bakteri rizosfer diperoleh dari sekitar akar tanaman bambu. Tujuan dari penelitian ini adalah Untuk mengetahui respon pertumbuhan tanaman kakao (Theobroma cacao L.), pada perendaman dan pemeberian microkapsul bakteri rizosfer dengan taraf perlakuan yang bervariasi. Desain penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL), 16 perlakuan dan 2 ulangan. Faktor pertama adalah perendaman biji kakao menggunakan suspensi bakteri rhizosfer yang terdiri dari A0=0 jam; A1= 8 jam; A2=16jam dan A3= 32 jam dan faktor kedua adalah penambahan mikrokapsul yang terdiri dari C0= 0 gr; C1=10 gram; C2= 20 gr; C3= 30 gram. Isolasi dari akar dan batang kakao diperoleh 9 isolat bakteri rhizosfer.

Abstract

This research aims to determine the response of growth and production of tomato plants (Solanum lycopersicum) to the application of cow dung fertilizer and egg shell POC. This research is located on Jl Madura, Kelurahan Pahlawan, Binjai City, North Sumatra Province. This research used a factorial randomized block design (RAK) consisting of two factors. The first factor is cow dung fertilizer (K) and the second factor is eggshell POC (C). The results showed that cow dung fertilizer and eggshell POC had a very significant effect on the parameters of plant height (cm), stem diameter (mm), number of fruit per plant (fruit), number of fruit per plot (fruit), fruit weight per plant (g ) and fruit weight per plot (g). The interaction between the application of cow dung fertilizer and eggshell POC had no significant effect on all observed parameters. Keywords: Tomato Plant, Cow dung, POC eggshell. INTISARIPenelitian ini bertujuan untuk mengetahui respon pertumbuhan dan produksi tanaman tomat (Solanum lycopersicum) terhadap pemberian pupuk kotoran sapi dan POC cangkang telur.
