Abstract

Dendrobium Sp orchid is one type of orchid that occupies the top position in ornamental plants. This study aims to determine the administration of various concentrations of magnesium sulfate (MgSO4) and Myo-inositol to Dendrobium Sp orchid explants on Murashige and Skoog media. The design used in this study was a factorial complete randomized design (CRD) consisting of 2 treatment levels (M= MgSO4 and Y= Myo-inositol) with 3 replications. Namely: M0 (without MgSO4), M1 (MgSO4 350 mg/l ), M2 (MgSO4 370 mg/l), M3 (MgSO4 390 mg/l), and Y0 (Without Myo-inositol), Y1 (Myo-inositol 50 mg/l), Y2 (Myo-inositol 100 mg/l) , Y3 (Myo-inositol 150 mg/l). Based on the results of the study, giving various concentrations of magnesium sulfate (MgSO4) alone had a significant effect on all observed parameters, where the best treatment was found in M3 with an average number of shoots 4.04, shoot height 1.08 cm, number of leaves 7.89 fruit, number of roots 6.64 fruit and root length 1.55 cm in Dendrobium Sp. For the treatment of various Myo-inositol concentrations, a single significant effect on all observed parameters, where the best treatment was found in Y3 with an average number of shoots 4.03, shoot height 1.25 cm, number of leaves 7.81, number of roots 4.96 and root length 1.48 in Dendrobium Sp. In interaction, the administration of MgSO4 and Myo-inisitol had a significant effect on all observation parameters, the best treatment was M3Y3 (390 mg/l MgSO4 and 150 mg/l MS Myo-inisitol) namely the number of shoots 4.33, the height of the shoots 1.68 cm, the number of leaves is 8.89, the number of roots is 7.22 cm and the root length is 2.02 cm.

Abstract

Dalam perekonomian makroekonomi Indonesia, industri minyak sawit memiliki peran strategis, antara lain penghasil devisa terbesar, lokomotif perekonomian nasional. Salah satu kendala yang dihadapi para petani kelapa sawit di Desa Siberoba adalah perawatan yang kurang optimal termasuk didalampemupukan tanaman belum menghasilkan.Petani yang memiliki ilmu pengetahuan yang kurang memadai dalam perawatan tanaman kelapa sawit, seringkali tidak melakukan pertimbangan konsistensi dalam teknis perawatan.Keadaan ini menimbulkan berbagai mudarat yang pada akhirnya merugikan petani yang pada akhirnya berdampak kepada pendapatan petani.Adapun metode pengabdian yang dilakukan adalah memberikan penyuluhan dan pelatihan tentang teknik pemupukan tanaman belum menghasilkan.Mulai dari persiapan pemupukan sampai tanaman bisa siap dipupuk.Berdasarkan data penyebaran kuesioner dari dua variabel yang dinilai yaitu kemampuan komunikasi dari tim pengabdian dan pengetahuan petani. Penilaian yang tertinggi pada variabel kemampuan komunikasi tim pengabdian terdapat pada jawaban 4 (mampu) yaitu 76%, sedangkan untuk variabel pengetahuan petani jawaban yang paling tinggi terdapat pada jawaban 4 (dapat menjawab 3 jawaban) yaitu 40%.

Abstract

Rice is a widely cultivated and consumed food commodity. In Indonesia, the increasing population growth has led to a rise in both rice consumption and demand. The purpose of this study was to determine the effects of gamma-ray treatment on the properties of Jangguik rice, specifically regarding seed growth duration, seedling height, number of leaves, and seedling weight. The research was conducted in Koto Kari Village, located in the Kuantan Tengah District of Kuantan Senggigi Regency. The Deputy provided gamma irradiation services for Research and Innovation Infrastructure at the Yogyakarta Radiation Laboratory, situated on Jl. Babarsari, Depok, Sleman, Yogyakarta. The research was conducted over two months, from June to July 2024. This experiment employed an experimental method utilizing a Randomized Block Design with one factor. The study consisted of five treatments, each repeated three times, resulting in a total of 15 experimental plots. The treatments tested included doses of 0 Gy, 100 Gy, 200 Gy, 300 Gy, and 400 Gy. The study's results were analyzed statistically using an ANOVA table. If the calculated F-value exceeded the F-value from the table at the 5% significance level, further analysis was conducted using the Honestly Significant Difference (HSD) test at the same significance level. The results of the study indicate that gamma-ray irradiation treatment exerts a multifaceted impact on the growth of Jangguik rice seedlings. The following data were collected for analysis: the parameter of seed growth days (0 Gy treatment: 3.41 days after planting; 300 Gy treatment: 6.06 cm); the number of leaves (200 Gy: 5.46 pieces); and the weight of 100 Gy seedlings (0.146 grams).

Abstract

Land conversion from rubber plantations to oil palm plantations is increasingly common in Indonesia, including in Pulau Binjai Village, Kuantan Mudik District, Kuantan Singingi Regency, Riau Province. Land preparation for oil palm plantations can affect soil fertility, particularly nutrient content. This study aims to evaluate the nutrient content in one-year-old oil palm plantations. The methods used in this study included surveys and laboratory analyses. Soil sampling was conducted at 10 locations using purposive random sampling at a depth of 20 cm, with 5 locations sampled using the grid method and 5 using the disc method. Each sample location consisted of 5 subsamples, which were then composited. The results showed that the soil pH in the grid ranged from 5.96 to 6.48 (acidic category), while in the disc it ranged from 6.2 to 6.88 (acidic to neutral category). The organic carbon content in the grid ranged from 2.61 to 3.74 (medium to high category), and in the plate from 2.82 to 4.28 (medium to high category). The total nitrogen content in the grid ranged from 0.20 to 0.25 (low to medium category), while in the plate it ranged from 0.21 to 0.29 (medium category). The C/N ratio in the grid ranged from 11.16 to 17.00 (medium to high category), and in the plate from 10.44 to 14.75 (low to medium category). The key findings of this research include the identification of organic carbon and nitrogen content in the soil, which enables recommendations for the application of organic and nitrogen fertilizers in the study area.

Abstract

Eggplant is widely appreciated as a food source across all levels of society and is among the most popular dishes in various communities. Therefore, the growth and production of eggplant require fertilizers to supply essential nutrients. Fertilizer materials can utilize potential waste, such as market waste. To increase the phosphorus content in liquid organic fertilizer, it can be enriched with maja fruit. Liquid organic fertilizer derived from market waste, consisting of vegetables and fruits, contains high levels of nitrogen, which is a fundamental component of protein and chlorophyll in plants. The purpose of this study was to determine the effect of applying liquid organic fertilizer (POC) made from market waste enriched with maja fruit on the growth and production of purple eggplant (Solanum melongena L.). The experimental research employed a Non-Factorial Completely Randomized Design (CRD). The treatments were as follows: A0 – no POC application; A1 – POC concentration of 100 ml per liter of water; A2 – POC concentration of 200 ml per liter of water; and A3 – POC concentration of 300 ml per liter of water. The results showed significant effects on flowering and harvest age. The treatment that produced the best results across all parameters was A2, which involved applying market waste POC enriched with maja fruit at a concentration of 200 ml per liter of water. However, this treatment did not significantly affect plant height (cm), fruit weight per plant (grams), or the number of fruits per plant. The liquid organic fertilizer produced contains high levels of essential nutrients, such as boron (B) and iron (Fe), which accelerate the generative phase, including flowering, thereby advancing the plant's harvest age.

Vocabulary was enhanced for better readability and precision, and sentence structure was refined to ensure a smooth flow and a professional tone appropriate for scientific writing.
