Abstract

The purpose of this study was to determine the most effective treatment of fertilizing doses on the results of quality tests of sprouts and growth of chilli seeds (Capsicum annuum) between bulk seeds, seeds in packaging, and direct extraction results seeds. The experimental method used was a factorial randomized block design. The first factor is the type of seeds, namely: bulk seeds (A), in packages (B), and direct extraction results (C). The second factor is the fertilizer dosage using NPK "Mutiara" (16:16:16), namely: 5 gr / l (X), 10 gr / l (Y), 15 gr / l (Z). The parameters observed included the number of live plants and the number of leaves. The results showed that the bulk seed germination power was 91.25%, the seeds were packaged and the results of direct extraction were 95.5%. After breeding and given fertilization treatment, it was found that fertilization with a dose of 5 gr / l showed the highest average growth compared to other treatments. So it can be concluded that fertilization with a dose of 5 gr / l is most effectively given to the seedling stage. Therefore fertilization with a dose of 5 gr / l is most recommended for seed producers so that the capital spent can be reduced.

Abstract

Lahan pertanian maupun perkebunan di Indonesia mengalami penurunan kesuburan akibat dari penggunaan pupuk kimia buatan berlebih yang menghilangkan unsur hara asli dari tanah. Kerusakan tanah ini juga diakibatkan oleh pH tanah yang terlalu asam. Keasaman pH tanah ini dapat berdampak pada penurunan produktivitas hasil pertanian maupun perkebunan. Melon adalah salah satu tanaman buah yang memerlukan pH netral selama pertumbuhannya sehingga didapatkan produktivitas maksimal. Penelitian ini bertujuan untuk mengetahui dampak pH terhadap soil recovery yang akan terlihat pada produktivitas melon. Penelitian ini dilakukan dengan pemberian perlakuan terhadap pengendalian pH menggunakan pupuk organik hayati berbasis microalgae Chlorella Pyrenoidosa yang terdapat dalam pupuk Chloten, urea, kapur serta tanpa perlakuan tambahan sebagai kontrol terhadap pH tanah yang berdampak pada produktivitas hasil panen melon. Parameter yang digunakan dalam penelitian ini adalah analisa pH tanah serta produktivitas melon. Perlakuan keasaman tanah menggunakan pupuk berbasis mikroalgae Chlorella pyrenoidosa tidak memiliki efek signifikan terhadap keasaman tanah serta produktivitas tanaman melon. Penggunaan pupuk berbasi microalgae Chlorella pyrenoidosa merupakan perlakuan terbaik yang didapat untuk mengatur keasaman tanah serta memiliki tingkat produktivitas hasil melon tertinggi. Agricultural land and plantations in Indonesia have decreased fertility due to the use of excess artificial chemical fertilizers that remove native nutrients from the soil. Soil damage is also caused by soil pH that is too acidic. The acidity of this soil pH can have an impact on decreasing the productivity of agricultural and plantation products. Melon is a fruit plant that requires a neutral pH during its growth in order to obtain maximum productivity. This study aims to determine the impact of pH on soil recovery which will be seen in melon productivity. This research was conducted by giving treatment to pH control using bio-organic fertilizer based on Chlorella Pyrenoidosa microalgae which is contained in Chloten, urea, lime and without additional treatment as a control for soil pH which has an impact on the productivity of melon yields. The parameters used in this study were analysis of soil pH and melon productivity. Soil acidity treatment using Chlorella pyrenoidosa microalgae-based fertilizer did not have a significant effect on soil acidity and the productivity of melons. The use of Chlorella pyrenoidosa microalgae based fertilizer is the best treatment obtained to regulate soil acidity and has the highest yield of melon yields.

Abstract

Tahun 2020 merupakan tahun yang cukup sulit bagi masyarakat Indonesia. Adanya virus corona jenis baru memaksa masyarakat untuk beradaptasi dengan kebiasaan baru. Salah satu masalah terbesar yang dihadapi adalah dengan adanya kebijakan lockdown  yang menyebabkan sulitnya distribusi bahan pangan. Oleh sebab itu edukasi masyarakat untuk memanfaatkan lahan pekarangan secara organik dengan mengoptimalkan sumber daya yang ada disekitar pekarangan rumah perlu dilakukan. Tujuan penelitian ini adalah untuk mengetahui respon tanaman cabai keriting dengan menggunakan pupuk fermentasi urin sapi. Penelitian dilakukan dengan cara memberikan perlakuan variasi pemupukan dengan mencampur urin sapi dan EM4 (perlakuan A); urin sapi, EM4, dan batang pohon pisang (perlakuan B); urin sapi, EM4, dan sabut kelapa (perlakuan C); dan urin sapi, EM4, dan akar kacang tanah (perlakuan D). Parameter yang diamati dalam penelitian ini adalah tinggi tanaman, jumlah daun, diameter batang, dan bobot biomassa kering tanaman.  Perlakuan penambahan sabut kelapa pada fermentasi urin sapi memberikan pengaruh yang nyata pada parameter tinggi tanaman. Sedangkan penambahan akar kacang tanah pada fermentasi pupuk urin sapi meningkatkan bobot biomassa kering tanaman secara signifikan. Penambahan batang pohon pisang pada fermentasi urin sapi secara nyata memberikan pengaruh terhadap diameter batang tanaman cabai keriting. Akan tetapi, jumlah daun tidak menunjukkan perbedaan yang signifikan dari semua jenis pemupukan. The year 2020 is quite a difficult year for the people of Indonesia. The existence of a new coronavirus type forces people to adapt to new habits. One of the biggest problems faced is the lockdown policy which makes it difficult for food distribution. Therefore, it is necessary to educate the public to utilize the yard organically by optimizing the existing resources around the yard of the house. This study aimed to determine the response of curly chili plants using cow urine fermentation fertilizer. The research was conducted by giving various fertilization treatments by mixing cow urine and EM4 (treatment A); cow urine, EM4, and banana tree trunks (treatment B); cow urine, EM4, and coconut husk (treatment C); and cow urine, EM4, and groundnut root (treatment D). Parameters observed in this study were plant height, number of leaves, stem diameter, and dry biomass weight of the plant. The addition of coconut fiber in cow urine fermentation has a significant effect on plant height parameters. Meanwhile, the addition of groundnut roots to fermented cow urine fertilizer increased the dry biomass weight of the plant significantly. The addition of banana tree trunks to cow urine fermentation significantly affected the stem diameter of curly chili plants. However, the number of leaves did not show a significant difference between all types of fertilization.

Abstract

A solvent extraction of 6- gingerol from fresh ginger rhizome chips using n-hexane has been successfully carried out. This study aimed to investigate the effects of temperature, feed size, and feed mass on the yield of gingerol, to observe the kinetics of gingerol extraction process using n-hexane as a solvent, to find the most influential parameters in the gingerol extraction process and to determine the optimum conditions of the gingerol extraction process. The experiment was carried out for 60 minutes using two feed mass ( 50 and 75 g), two temperature (60 and 70 oC) and two chips sizes (100 and 25 mm3) using 350 mL n-hexane. The second-order kinetics model was used to study the extraction kinetic parameters. The quick method was used to evaluate the most influential extraction parameters with respect to the yield of gingerol. Feed mass was found to be the most influential parameter in the gingerol extraction process. The optimum extraction conditions were found to be at 60 °C, ginger rhizome chips with 25 mm size3, feed mass was 109.7g and 350 mL n-hexane, which resulted in crude extract with gingerol content of 517.11 ppm.
