Abstract

Sweet corn (Zea mays saccharata L.) is a plant that contains more carbohydrates so that it becomes one of the second most important commodities after rice, both as a source of food and feed. The objectives of this study were to obtain the best Paclobutrazol Concentration on the Growth and Yield of Sweet Corn on Peat Soil in Rasau Jaya 2 and to obtain the best Planting System on the Growth and Yield of Sweet Corn on Peat Soil in Rasau Jaya. The research was conducted on Mr. Sugianto's land located at Patok 28, Rasau Jaya 2 Village, Rasau Jaya District, Kubu Raya Regency. This research took place from July 24, 2023 - September 30, 2023. This study used a Split Plot Design consisting of 2 factors. The first factor is the concentration of Paclobutrazol (P) which consists of 4 treatment levels and the second factor is a modified double row planting system (D) with 3 treatment levels, so that the total treatment combination is 12. Each treatment combination was repeated 3 times and each treatment unit consisted of 5 plant samples.  In the Split Plot Design, Paclobutrazol concentration (P) was used as the main plot, while the modified double row planting system (D) was used as a sub plot. The observed variables were plant height, stem diameter, number of leaves, plant fresh weight, plant dry weight, leaf area, root volume, ear weight per plot, weight of ear, weight of ear without shell, weight per ear without shell, ear with shell and ear without shell. Observation data were statistically analyzed using variance (F test at 5% level). If the F test showed a real effect, then the Honestly Significant Difference (HSD) test was continued at the 5% level. On the basis of the results of the study, it can be concluded that the single application of paclobutrazol can suppress the plant height but has the same effect of reduction of plant height by 3-5 cm. The planting system (15+15) cm x 80 cm with the use of paclobutrazol 1000 ppm can increase the weight of cob per plot better than other planting systems. Keywords: Soil, Sweet Corn, Paclobutrazol, Planting System. INTISARIJagung manis (Zea mays saccharata L.) merupakan tanaman yang mengandung karbohidrat lebih banyak sehingga menjadi salah satu komoditi terpenting kedua setelah padi, baik sebagai sumber pangan maupun pakan. Tujuan penelitian ini adalah untuk mendapatkan Konsentrasi Paclobutrazol terbaik terhadap Pertumbuhan dan Hasil Jagung Manis pada Tanah Gambut di Rasau Jaya 2 dan untuk mendapatkan Sistem Tanam terbaik terhadap Pertumbuhan dan Hasil Jagung Manis pada Tanah Gambut di Rasau Jaya. Penelitian dilaksanakan di lahan Bapak Sugianto yang berada di Patok 28, Desa Rasau Jaya 2, Kecamatan Rasau Jaya, Kabupaten Kubu Raya. Penelitian ini berlangsung dari tanggal 24 Juli 2023 – 30 September 2023. Penelitian ini menggunakan Rancangan Petak Terbagi (Split Plot Design) yang terdiri dari 2 faktor. Faktor pertama yaitu konsentrasi Paclobutrazol (P) yang terdiri dari 4 taraf perlakuan dan faktor kedua adalah modifikasi Sistem Tanam double row (D) dengan 3 taraf perlakuan, sehingga total kombinasi perlakuan sebanyak 12 . Setiap kombinasi perlakuan diulang sebanyak 3 kali dan masing-masing unit perlakuan terdiri 5 sampel tanaman.  Pada rancangan Split Plot Design konsentrasi Paclobutrazol (P) dijadikan petak utama (main plot), sedangkan modifikasi Sistem Tanam double row (D) dijadikan sebagai anak petak (sub plot). Variabel yang diamati yaitu tinggi tanaman, diameter batang, jumlah daun, bobot segar tanaman, bobot kering tanaman, luas daun, volume akar, bobot tongkol per petak, bobot per tongkol berkelobot, bobot per tongkol tanpa kelobot, panjang tongkol dan diameter tongkol. Data hasil pengamatan dianalisis secara statistik dengan menggunakan varians (uji F taraf 5%). Apabila uji F menunjukkan adanya pengaruh nyata, maka dilanjutkn uji Beda Nyata Jujur (BNJ) pada taraf 5%. Berdasarkan hasil penelitian maka dapat disimpulkan bahwa pemberian paclobutrazol secara tunggal dapat menekan tinggi tanaman namun memberikan pengaruh yang sama pengurangan tinggi tanaman 3-5 cm. Sistem tanam (15+15)cm x 80 cm dengan penggunaan paclobutrazol 1000 ppm dapat meningkatkan bobot tongkol perpetak lebih baik dibandingkan sistem tanam lainnya. Kata Kunci : Gambut, Jagung Manis, Paclobutrazol, Sistem Tanam.

Abstract

This research aims to determine the efficiency and pattern of pineapple marketing channels in Pangkul Village, Cambai District, Prabumulih City. This research was carried out from March to April 2023. The sampling method used purposive sampling of 16 farmers, 1 collector and 6 retailers. To determine the marketing efficiency of pineapples, quantitative analysis is used, while to determine the pineapple marketing channel patterns, descriptive analysis is used. The research results show that there are three (3) marketing channel patterns for pineapple fruit, namely: channel pattern I. Farmers sell their harvest to collectors and collectors sell to factories. Channel pattern II Farmers sell their crops to retailers and retailers sell to final consumers. Channel III pattern: farmers sell their crops to collectors, then collectors sell to retailers and retailers sell to final consumers. Of the three pineapple marketing channel patterns, it turns out that marketing pattern I is efficient compared to marketing patterns II and III. Judging from the margin and farmer's share results, marketing channel pattern I is said to be efficient, because the marketing margin value is lower and the farmer's share is higher, namely 52. 8% of marketing channel patterns II and III. The highest profit is found in marketing channel pattern III IDR  10,739.7/piece. In marketing channel pattern I, the profit obtained by collectors is IDR  1,782/piece, marketing costs IDR  577/piece and margin IDR  2,360/piece. In marketing channel pattern II, the retailer's profit is IDR  10,539.7/piece, marketing costs IDR  1,626.3/piece, and a margin of IDR  4,055.33/piece.

Abstract

The quality of organic fertilizer produced from the composting process depends on the basic ingredients used and the length of time for composting. The quality of organic fertilizer that meets the standards will affect soil fertility and plant growth. The aim of this research was to see the effect of the length of composting time on the nutrient content of KoHeA+MF organic fertilizer.. The length of composting time is 7, 14 and 21 days. The parameters observed included pH, C-organic, N-total, P2O5, K2O, Mg-total, Ca-total and CEC. The results obtained at 21 days the content of C-organic, N-total, P2O5 and CEC was higher compared to 7 and 14 days. In general, the length of composting time does not really affect the nutrient content of the KoHeA+MF organic fertilizer produced. At 7 days composting time has met the quality standards of organic fertilizers that can be used to improve soil fertility and increase crop production.

Abstract

This research aims to determine the interaction between IBA concentration and growth media composition. Apart from that, determine the provision of IBA and the best composition of growing media for the formation of roots and shoots of rose cuttings. This research was carried out for 4 months, starting from March to June 2022 at the UPT Farm Experimental Garden, Faculty of Agriculture, Andalas University, Padang. The design used was a Factorial Design with 2 factors arranged in a Completely Randomized Design (CRD). The first factor is the provision of IBA which consists of 4 levels (0; 50; 100; 150 ppm). The second factor is the composition of the growing medium which consists of 3 levels: (soil + charcoal husk + cow manure; soil + coconut fiber powder (cocopeat); soil + sand + cow manure). The research data were analyzed statistically using the F test at the 5% level. If the calculated F is greater than the F table of 5%, then proceed with the Duncan's New Multiple Range Test (DNMRT) at level 5. The results of the research show that there is no interaction between the concentration of IBA (Indole-3 butyric acid) and the composition of the growing media in root formation and rose cuttings. The best IBA concentration for forming roots and shoots from rose cuttings is a concentration of 100 ppm, while the best growing medium for forming roots and shoots from rose cuttings is soil + sand + cow manure.

Abstract

known as "dragon fruit" which is widely cultivated in various countries in Asia. The high demand for dragon fruit makes the availability of seeds for dragon fruit development difficult. The in-vitro technique is a suitable alternative to provide large quantities of seed in a short time. Media and growth regulators are the determining factors for explant growth. The combination of NAA and BAP is suitable for dragon fruit, which is useful for triggering cell division in the tissue made by explants and triggering shoot growth, root formation, stem elongation and root elongation. The purpose of the study was to obtain the best interaction of Naphtaleine Acetic Acid and Benzyl Amino Purine concentrations for dragon fruit subculture growth. This study used a Factorial Completely Randomized Design (CRD) consisting of two factors, namely Naphtaleine Acetic Acid concentration (0.2 ppm, 0.4 ppm, 0.6 ppm, 0.8 ppm) and Benzyl Amino Purine concentration (1 ppm, 2 ppm, 3 ppm 4 ppm) with each consisting of 4 concentration levels, resulting in 16 treatment combinations. The treatment was repeated 3 times and each treatment unit consisted of 4 samples. The variables observed in this study were the percentage of sprouted explants (%), the time of the first shoot (week after planting), the number of shoots (buds), the time of the first root appearance (week after planting) and the number of roots (strands). The results showed that the interaction of NAA and BAP concentrations did not produce the best interaction concentration effect on dragon fruit explants so that the objectives were not achieved. At a concentration of 0.6 ppm NAA is effective in increasing the number of roots of dragon fruit explants and a concentration of 1 ppm BAP is effective in accelerating the time of root emergence and increasing the number of roots of dragon fruit explants.
