ion Food, Agriculture and Fisheries Department of Medan City, Jl. Keramat Indah No. 4, Medan Southeast, Medan Denai District, North Sumatra. The experimental design that The design used in this study was a Randomized Block Design (RAK) with 3x3 factorial pattern with 3 replications with total treatment combinations as many as 9 treatments. Treatment factor of Blotong dose with symbol B consisting of 3 level that is : (B1) 0.50 kg/plot (B2) 1.00 kg/plot (B3) 1.50 kg/plot. Factor POC Seprint concentration with the symbol S which consists of 3 levels, namely: (S1) 4 ml/1 L water (S2) 8 ml/1 L water and (S3) 12 ml/1 L water. Observation data was carried out analysis of variance with F test at 5% level, if the difference is significant then the test followed by Duncan's test at 5% level. 1). The effect of the Blotong dose has an effect very real on plant height, number of leaves, flag leaf length, leaf width flag, weight of cob, diameter of cob, length of cob, but it has an effect real on production per plot And amount line per cob, whereas had no significant effect on the stem diameter of sweet corn plants ( Zea Mays ). 2). Based on the results and discussion, it can be concluded that the treatment POC Seprint does not have a very significant impact on all parameters Which observed. Addition fertilizer Seprint with concentration 12 ml/1 L water show results Which best compared to treatment other. 3). Interaction between treatment influences Blotong and POC Seprint no real effect on all observation parameters observed on sweet corn plants ( Zea Mays ).

Ujung and Kramat are beautiful. between May and June 2023. The factorial randomized block design (RAK) used in this study consisted of two treatment factors symbolized by the symbol A at three levels, namely: A1) half KL (A2) 75% KL and (A3) 100 percent KL. The next factorial is with image P which consists of 3 levels, namely; (P1) is 1 g per liter of water, P2 is 2 g per liter, and P3 is 3 g per liter of water. With the aim of obtaining 9 drugs. Each treatment is repeated several times. The perception information is then investigated using the F test for changes at the 5% level. If the problem is large then proceed with the Duncan test. From the results of the examination and discussions carried out, results were obtained, including: 1). The influence of water pressure has a significant effect on plant height, number of leaves, leaf width, wet weight, and influences leaf length, leaf area and stem size of mustard greens (Brassica juncea L.). 2). Giving Gandasil D at a dose of 3 g/l of water basically increases the number of plants, number of leaves, leaf length, leaf width, stem size, new weight per plant, and selling weight. 3). The relationship between water stress treatment and use of leaf compost fundamentally affects plant height, number of leaves, leaf width, and wet load in mustard greens (Brassica juncea L.) while leaf length, leaf area and cross stem distance do not make a big difference.

ssica rapa L), to determine the effect of watering frequency on the growth and yield of pakcoy (Brassica rapa L) and to determine the effect of both on the growth and yield of pakcoy (Brassica rapa L). Based on the results of the study, the treatment of Gandasil D fertilizer had a very significant effect on plant height, number of leaves, leaf area, wet weight, selling weight with a fertilizer concentration of 3 g / l water and a watering frequency of 1 time in one day compared to 1 time in 3 days of watering and the interaction between the treatment of Gandasil D fertilizer and watering frequency had a significant effect on plant height, number of leaves, leaf area, wet weight, and selling weight.
Abstract:This study expects to determine the impact of cow compost and urea manure to increase yields and ideal plant development. This exploration was completed at the Medan City Food Security Administration, Jl. Delightful Kramat/Selambo…
at/Selambo Ujung. From May to August 2023. This study utilized a factorial randomized bunch plan (RBD) which comprised of 2 treatment factors with the image S which comprised of 3 levels, in particular; ( S1) 1 kg/plot (S2) 2 kg/plot and (S3) 3 kg/plot. The subsequent factorial is the U image which consists of 3 levels to be specific; (U1) 30 g/plot (U2) 40 g/plot and (P3) 50 g/plot. With the goal that 9 medicines were obtained. Every treatment was rehashed multiple times. The perception information was then examined with the F trial of change at the 5% level, in the event that the thing that matters was huge, the test was gone on with the Duncan test. From the aftereffects of the examination and conversation completed, the accompanying ends were obtained: 1). The impact of cow fertilizer application affected plant level, number of leaves, number of blossoms, number of cases and unit weight of bean plants (Phaseolus vulgaris L.) 2). The impact of applying urea manure meaningfully affected plant level, significantly affected the quantity of leaves, fundamentally affected the quantity of blossoms and affected the quantity of cases and unit weight of bean plants (Phaseolus vulgaris L.) 3). The communication between the treatment of cow excrement and urea manure essentially affected plant level, number of blossoms, number of cases and unit weight, but not altogether unique on the quantity of leaves of bean plants (Phaseolus vulgaris L.)

of June--September 2023. RAK or Randomized Block Design through factorial with two treatment factors was used as the method of this research. Three levels namely: D1 = 0 g / plot (0 kg / ha), D2 = 40 g / plot (270 kg / ha), D3 = 60 g / plot (400 kg / ha), the three of them became the first factor of dolomite (D) dosage which was grouped into three levels. In addition, N1 = 30 g / plot (200 kg / ha), N2 = 45 g / plot (300 kg / ha), N3 = 60 g / plot (400 kg / ha), the three of them became the second factor of NPK Mutiara fertilizer dosage which was divided into three levels. Dolomite application, 60 g/plot produces optimal yield and growth of peanut plants, namely the weight of 100 dry seeds, plant height, pod weight per plot, flowering age, pod weight per plant, number of branches, number of filled pods per plant, number of gynophores per plant, number of empty pods per plant, and total number of pods per plant are significantly affected by dolomite application. Meanwhile, application of NPK Mutiara fertilizer with a dose of 60 g/plot shows the same thing. The combination of dolomite and NPK Mutiara fertilizer only has a significant effect on the number of gynophores per plant.

daerah dengan prevalensi overweight dan obesitas balita tertinggi di Indonesia. Penelitian ini bertujuan untuk menganalisis faktor determinan kejadian overweight dan obesitas pada anak usia 24–59 bulan di Provinsi Kepulauan Bangka Belitung. Penelitian ini menggunakan desain observasional analitik dengan pendekatan cross-sectional dan memanfaatkan data sekunder Survei Kesehatan Indonesia (SKI) Tahun 2023. Sampel penelitian berjumlah 584 anak usia 24–59 bulan. Variabel independen meliputi jenis kelamin, riwayat berat badan lahir, kelengkapan imunisasi, serta konsumsi makanan manis, minuman manis, dan makanan berlemak. Analisis data dilakukan menggunakan uji chi-square dan regresi logistik sederhana untuk memperoleh nilai Odds Ratio (OR) dan interval kepercayaan 95%. Hasil penelitian menunjukkan prevalensi overweight dan obesitas sebesar 11,8%. Analisis bivariat menunjukkan bahwa jenis kelamin laki-laki berhubungan signifikan dengan kejadian overweight dan obesitas (OR=1,78; IK 95%=1,06–2,98; p<0,05). Sementara itu, riwayat berat badan lahir, kelengkapan imunisasi, serta konsumsi makanan manis, minuman manis, dan makanan berlemak tidak menunjukkan hubungan yang bermakna secara statistik. Kesimpulan penelitian ini menunjukkan bahwa jenis kelamin laki-laki merupakan faktor determinan utama kejadian overweight dan obesitas pada anak usia 24–59 bulan di Provinsi Kepulauan Bangka Belitung. Diperlukan intervensi gizi preventif sejak dini yang terintegrasi dengan pemantauan pertumbuhan balita.
