Abstract

Caisim is one type of leaf vegetable that is favored by Indonesian consumers because it contains various nutrients that are nutritious for health. This study aims to compare the effect of using several types of organic fertilizers compared to inorganic fertilizers on the growth of caisim mustard plants. This study used a Simple Randomized Block Design (RAK). There are 7 types of treatment, including: P0 = No fertilizer application, P1 = NPK fertilizer 1 gram per pot, P2 = Compost fertilizer, P3 = Cow manure, P4 = Chicken manure, P5 = Vermicompost fertilizer, and P6 = Vermicompost nano fertilizer. The dose of organic fertilizer applied is equivalent to the N content of NPK fertilizer. The resulting data were analyzed (F test variety) with a level of 5% to determine the effect of treatment. If the results of the F test have a significant effect, then continue with the further BNT test with a level of 5% to determine the effect of growth on plant yields. The results showed that in general the P6 treatment (nano vermicompost fertilizer) gave the best growth response on the variable number of leaves and leaf area. Based on the research that has been done, it is recommended that in the cultivation of mustard caisim the right fertilizer is used, namely nano vermicompost fertilizer. Keywords: Caisim, Nano vermicompost, Growth response

Abstract

Caisim mustard (Brassica juncea L.) is a type of leaf vegetable that contains a variety of complete nutrients that are widely used by the community. This study aims to obtain the optimum dose of biological fertilizer application that can increase the productivity of growth and yield of caisim mustard plants. The research was carried out on the agricultural land of the Sri Anom IV Temas farmer group, Batu District, Batu City for 2 months starting from December 2021 to January 2022. The design used was a Simple Randomized Design consisting of one factor, namely Petrobio (H) biofertilizer. Petrobio (H) biofertilizer application consists of 4 levels, namely H0 (without biofertilizer), H1 (50 kg/ha), H2 (100 kg/ha), H3 (150 kg/ha). From the design that has been described, each experimental unit was repeated 3 times and each treatment unit used 4 samples, so that 48 samples were obtained. The results of this study indicate that the application of Petrobio biofertilizer is able to provide real growth and yield of caisim mustard plants. The use of Petrobio H1, H2 and H3 biofertilizers gave an equally good response to the number of leaves. The H2 and H3 treatments gave the same good response to plant height and plant dry weight. While the H3 treatment gave an equally good response to plant fresh weight and plant economic weight. From the results of the regression analysis, the optimum dose of Petrobio biofertilizer was 174 kg/ha with an economic weight of 136.882 grams/plant.Keywords : Caisim mustard plant, Petrobio biofertilizer.

Abstract

Kailan cultivation is generally done by farmers using inorganic fertilizers. This kind of farming system in the long term is detrimental to farmers because the soil will become infertile, the quantity and quality of vegetables will decrease. This study aims to compare the effect of using several kinds of organic fertilizers compared to inorganic fertilizers on the growth of kailan plants. This study used a Simple Randomized Block Design (RBD). There were 7 kinds of treatments, including: P0 = No fertilizer application, P1 = NPK fertilizer 4.5 g/pot, P2 = Compost fertilizer 218 g/pot, P3 = Cow dung fertilizer 397 g/pot, P4 = Chicken manure fertilizer 111 g /pot, P5 = Vermicompost fertilizer 511 g/pot, and P6 = Vermicompost powder fertilizer 147 g/pot. The dose of organic fertilizer applied is equivalent to the N content in NPK fertilizer and converted to the water content of the organic fertilizer. The variables observed included: plant height, number of leaves, leaf area and chlorophyll content. The data collected were analyzed for variance (F test) with a level of 5% to determine the effect of treatment. If the results of the F test have a significant effect, then continue with the further LSD test with a level of 5% to determine the effect of growth on plant yields. The results of this study indicate that at the end of the observation of plant growth (plant height and leaf area) the best was found in the vermicompost treatment, while the number of leaves of inorganic fertilizer, compost, vermicompost and vermicompost powder gave the same number of leaves. However, when viewed from the level of green leaf color (chlorophyll content) as measured by using a SPAD meter, vermicompost powder gave the highest chlorophyll content. Keywords : Kailan, Fertilizer, Growth response

Abstract

Since open-field agriculture will face some severe problems in the near future like availability of land and agricultural productivity, an alternative cultivation system, such as soilless cultivation is needed for the sustainability of supply and demand for healthier and safer food. This study aimed to test the effect of vermicompost application method and dosage on growth, yield, and chlorophyll content of water spinach. This experiment used a factorial randomized block design with controls. The first factor was the vermicompost application method, which consisted of three levels, namely solid vermicompost, the combination of solid and liquid vermicompost, liquid vermicompost. The second factor was the vermicompost dosage, which consisted of five levels: 100, 200, 300, 400, and 500g per polybag, compared with control using inorganic fertilizer. The results showed that the vermicompost application method did not significantly affect plant growth and yield. The dosage of 500g in the three different application methods gave significantly higher plant growth compared to control. The fresh weight of water spinach per plant and per polybag in the dosage of 500g showed the highest yield of 13.95g and 122.17g, respectively. The highest chlorophyll content of water spinach was found in solid vermicompost treatment with an application rate of 500g, namely 30.10 µg/ml (chlorophyll A) and 54.79 µg/ml (chlorophyll B). These results indicate that to produce high-quality water spinach in soilless culture systems, it is recommended to use solid vermicompost with an application rate of 500g per polybag.

Berdasarkan UU No. 16 tahun 2007 tentangstandar kualifikasi akademik dan kompetensi guru dijelaskan bahwaguru dituntut untuk memanfaatkan teknologi informasi dan komunikasidalam pembelajaran yang diampu. Dengan ini guru harus mampumelaksanakan pembelajaran dengan mengunakan teknlologi danjugadituntut untuk mengembangkan teknlologi di berbagai mediapendidikan. Salah satu teknologi yang dapat digunakan peserta didikdimanapun, kapanpun, dan didukung fitur-fitur menarik yaituhandphone. Menurut Rahayu (2017:16) istilah mobile learning (mleraning)mengacu kepada pengunaan perangkat teknologi (TI)gengam dan bergerak, seperti PDA, telepon gengam, laptop, dan tabletPC, dalam pengajaran dan pembelajaran. Mobile learning dapatdigunakan peserta didik untuk belajar secara mandiri, dandimungkinkan dapat di akses untuk belajar peserta didik tanpa terikatruang dan waktu. Sehinga media pembelajaran yang memanfaatkanhandphone dapat disebut mobile learning. Penelitian pendahuluan iniakan dilanjutkan ke penelitian selanjutnya untuk mengetahuikelayakan media pembelajaran berbasis mobile learning padaplatfrom android dengan mengunakan App Inventor untukmeningkatkan kemampuan berpikir kritis peserta didik.
