Abstract

Bayam hijau adalah jenis sayuran yang digemari oleh semua lapisan masyarakat namun peningkatan permintaan bayam hijau di Indonesia belum diimbangi dengan ketersediaan bayam hijau yang cukup dikarenakan semakin berkurangnya lahan subur untuk pertanian bayam hijau. Hal ini disebabkan adanya praktik penggunaan pupuk anorganik oleh para petani secara berlebihan atau terus menerus sehingga berdampak buruk bagi tanaman, tanah, maupun lingkungan. Salah satu alternatif untuk membenahi tanah, lingkungan, maupun tanaman bayam hijau ini ialah dengan penggunaan pupuk organik yang berasal dari limbah bakpia dan tahu karena masih mengandung sumber nutrien bagi tanaman. Tujuan penelitian ini adalah menentukan pengaruh POC limbah bakpia dan tahu terhadap pertumbuhan bayam hijau serta menentukan konsentrasi optimum POC limbah bakpia dan tahu dalam mempengaruhi pertumbuhan bayam hijau berupa tinggi batang, panjang daun, lebar daun, berat basah tanaman, berat kering tanaman, dan kadar klorofil. Variabel bebas dalam penelitian ini adalah konsentrasi POC limbah bakpia dan tahu dengan 5 ulangan dan 5 taraf perlakuan (K = 0 ml/L, P1 = 55 ml/L, P2 = 60 ml/L, P3 = 65 ml/L, dan P4 = 70 ml/L) sehingga terdapat 25 unit percobaan. Berdasarkan penelitian yang dilakukan, pemberian POC limbah bakpia dan tahu berpengaruh secara nyata terhadap pertumbuhan tanaman bayam hijau berupa tinggi batang, berat basah tanaman, dan berat kering tanaman serta konsentrasi POC limbah bakpia dan tahu yang berpengaruh paling baik terhadap pertumbuhan tanaman bayam hijau adalah 55  ml/L. Kata kunci: bayam hijau, pupuk organik cair, limbah bakpia dan tahu

Abstract

Lecturers as educators must be able to transform into agents of change, agents of analysis, and agents of control towards a strong Indonesia. All of this is in the context of advancing the public interest, educating, and advancing the life of the nation and state. Efforts are being made to implement the Tri Dharma of Higher Education, including education, research, and community service. This study aims to determine the real contribution of lecturers in realizing quality higher education outputs through the implementation of the Tri Dharma of Higher Education. This type of research is descriptive research using the survey method. From the results of this study, it can be suggested that lecturers are a key element to improve qualifications, competencies, and professionalism.

Abstract

Fungal diversity is high in Indonesia, one of which is Scleroderma sp. Scleroderma forms a symbiotic relationship with Gnetum gnemon. Its fruiting body is puff-ball shaped, and its gleba can be consumed because of its taste and nutritious. Study on the Scleroderma’s diversity in Purworejo Regency has not been done. In this study, morphological characteristics were used as main identification character. Scleroderma samples were collected from Grabag, Kemiri, and Kaligesing and then observed their morphology and spore characteristics. Morphological traits observed on fruit body shape (globose and kidney-shaped); and ornamentation on peridium layer (cracked, nodule and peeling). Chemical content, temperature, and humidity of the soil were also observed as supporting data.

Abstract

Red spinach is widely cultivated and consumed by the public because it has high antioxidants, vitamins (A, C, E), protein, carbohydrates, fats, minerals, iron, magnesium, manganese, potassium and calcium. P giving POC can increasered spinach biomass. Nutrients in POC have been decomposed so that they are easily absorbed by plants. This study aims to analyze the giving of POC Lemna sp. on growth and biochemical content of red spinach and determine the concentration of POC Lemna sp. effective for red spinach (Amaranthus tricolor L.). The study used a completely randomized design with 3 replications and 3 treatments. The independent variable in this study was the concentration of liquid organic fertilizer Lemna sp. (A=0%, B=5%, and C=10%). Data were analyzed by ANOVA test and DMRT test at 5% level. The results showed that the administration of POC Lemna sp. gave significantly different results on the A (0%) treatment of plant height, stem diameter, and flavonoid parameters. Giving POC Lemna sp. can increase the growth and flavonoid content of red spinach. The concentration of liquid organic fertilizer Lemna sp. 5% effective for the growth of red spinach (Amaranthus tricolor L.).

Abstract

Green lettuce (Lactuca sativa L.) is a vegetable crop that is in great demand by the public, but its production is relatively low so that it cannot meet the high market demand. One of the efforts to increase the production of green lettuce plants is by applying organic fertilizer. The purpose of this study was to determine the content of C, N, P, K elements, the effect of compost application for growth and optimal dosage. The research method used a complete randomized design (CRD) four treatments namely Control, A (dose of 60 g), B (dose of 120 g) and C (dose of 180 g) with 5 replications. Data from the study were analyzed using the Anova test, significant data continued with the DMRT 5% further test. Testing the effect with simple liner regression analysis. The results showed that compost gave a blackish brown color after 35 days and had no odor and obtained nutrient values of C (41,77%), N (6,92%), P (0,09%) and K (0,12%). The treatment of compost variations produced plant height of 26,80 cm, number of leaves of 10,60 leaf, plant wet weight of 22,40 gram, root weight of 0,57 gram, root length of 12,94 cm leaf area of 130,06 cm² with significant results, while chlorophyll A (0,19 mg/L) and total (0,616 mg/L) levels had insignificant results. The conclusion of the research is that the compost of banana stalks and cow blood meal contains C by 41,77%, Total N by 6,92%, Total P by 0,09% and Total K by 0,12%. Banana pith compost and cow blood flour had a significant effect on all parameters of green lettuce plant growth except leaf chlorophyll content at the most optimal dose was treatment A (dose of 60 g).
