Abstract

Sorghum (Sorghum bicolor L. Moench) is prospective crop for food as well as feed and bioenergy. It adapts to wide agroclimate and agroecology. However, the productivity is accounted low in Indonesia. Low productivity of sorghum can be enhanced through intensification, e.g., precise dose of nitrogen and phosphorus fertilizers application. The aim of this research was to determine the optimum dose of nitrogen and phosphorus fertilizers to maximize growth and yield of sorghum in latosol soil, in order to develop fertilizer recommendation on specific soil type. The research was conducted at Cikarawang, Bogor from March to July 2015. Nitrogen and phosphorus fertilizers were arranged and applied simultaneously using randomized completely block design with three replications. Nitrogen fertilizer was applied in five levels, i.e., 0, 60, 120, 180, 240 kg N ha-1 and phosphorus levels were 0, 18, 36, 54, 72 kg P2O5 ha-1. Results showed that the application of nitrogen and phosphorus fertilizers significantly increased vegetative growth and yield components. The optimum dose were 161 kg N ha-1 (133.7%) and 43 kg P2O5 ha-1 (121.5%) for latosol soil.Keywords: fertilizer, optimum dose, soil type, vegetative, yield component

Abstract

Development of sorghum processing industries is essential in expanding sorghum market as wells as it’s an economic value. Fertilizer is needed in planting. Nitrogen, phosphorus, and potassium availabilities are the most limiting factors for maximum growth and yield. Sorghum (Numbu Variety) was planted to evaluate the maximum and optimum rates of N, P, and K fertilizers. The research was conducted in Cikarawang field, Darmaga, Bogor from MarchJuly 2015 with multi-nutrient response method. Each experiment evaluated different rates of N, P, and K fertilizer with randomized complete block design and three replications. The fertilizer rates were 0, 50, 100, 150, and 200% of recommendation rate (100% N = 120 kg N ha-1, 100% P = 36 kg P2O5 ha-1, and 100% K = 90 kg K2O ha-1). The result showed relative yields of sorghum increased quadratically based on y = -0,0015x2 + 0,4011x + 67,571 for N, y = -0,0012x2 + 0,2917x + 78,457 for P2O5, and y = -0,001x2 + 0,2777x + 74,457 for K2O. The maximum rate for each nutrient was 160,4-43,7-124,9 kg N-P2O5-K2O ha-1. Fertilizer recommendation based on P threshold (no P) was 36,7-0,0-13,7 kg N-P2O5-K2O ha-1, K threshold (no K) was 22,0-0,0-0,0 kg N-P2O5-K2O ha-1, and no fertilizer needed on N threshold. The optimum rate fertilizer based on the yield vs. cost rule, therefore, the most economical recommendation would be 160,4-43,7-124,9 kg N-P2O5-K2O ha-1.

Abstract

The need for nutrients for the body continues to increase, while the fulfillment of these nutrients is very limited. Through vegetables, fulfilling nutrients for the body, namely vitamins and fiber. However, currently the problem faced regarding vegetable production is limited space for vegetable cultivation. This is due to many factors, one of which is the conversion of agricultural land. Microgreen is an alternative that can be applied to overcome this problem. Microgreens are young plants that are rich in fiber and vitamins and are very good for fulfilling the body's nutrition. The focus of the research is to study how the planting medium affects the growth and quality of microgreens in mustard and lettuce plants. This study was conducted in Jambewangi from August to November 2024, using a completely randomized design , it involves 2 factors, each with 3 replications: planting medium (charcoal husk, cocopeat, malang sand, rockwool) and type of vegetables (mustard greens and lettuce). The results of the study showed that there was a real interaction between the type of vegetables and the planting medium on the fresh weight of plants in aged 11 HST, with the best results on husk charcoal x mustard greens, and the interaction between the type of vegetable and the planting medium also had a significant effect on the germination of rockwool x lettuce. The highest protein content was found in the cocopeat x lettuce treatment interaction (16.80%), while the total chlorophyll was the highest, namely 6.12 µmolm-2.

Abstract

Pengelolaan sampah organik menjadi salah satu tantangan besar di Indonesia, mengingat tingginya volume sampah yang terus meningkat setiap tahun. Sampah organik yang sebagian besar berasal dari sisa makanan dan bahan organik lainnya sering kali dibuang tanpa pemanfaatan. Padahal, jika dikelola dengan baik, sampah organik dapat diubah menjadi pupuk yang bermanfaat, salah satunya melalui teknologi eco enzyme. Penelitian ini bertujuan untuk mengedukasi masyarakat, khususnya ibu rumah tangga, mengenai cara mengolah sampah organik menjadi eco enzyme yang dapat digunakan sebagai cairan pembersih dan pupuk alami. Kegiatan ini dilakukan di Dusun Jambewangi, Kab. Magelang, dengan metode pengabdian masyarakat yang mencakup sosialisasi dan pelatihan pembuatan eco enzyme dari sisa sayuran. Hasil dari pelatihan menunjukkan bahwa peserta sangat antusias dan memperoleh pengetahuan baru tentang pengelolaan sampah organik. Dengan pemahaman ini, diharapkan masyarakat dapat lebih peduli dalam mengelola sampah organik dengan cara yang lebih ramah lingkungan, sekaligus memanfaatkan limbah rumah tangga untuk menghasilkan produk yang berguna seperti eco enzyme.

Abstract

The decreasing area of agricultural land due to conversion to residential use threatens food security and the sustainability of the agricultural sector, so efficient and nutritious cultivation alternatives are needed. Microgreens, young vegetables that are rich in nutrients and can be cultivated on limited land, are a potential solution whose success is greatly influenced by the growing medium. This study aimed to analyze the effect of growing media on the growth and protein of spinach and kale microgreens. The research was conducted in Jambewangi in August-November 2024 using a two-factor completely randomized design (CRD), namely planting media (husk charcoal, cocopeat, Malang sand, and rockwool) and vegetable types (kale and spinach greens), each with three replications. The results showed a significant interaction between vegetable species and planting media on the fresh weight of plants at the age of 14 HST. The best treatment was found in husk charcoal × kale, cocopeat × kale, and rockwool × kale. The highest protein content was recorded in sand × spinach (6.05%), while the highest total chlorophyll was in cocopeat × kale (38.80 µmolm-²). The selection of appropriate growing media proved to have a significant effect on the vegetative growth and nutritional quality of microgreens.

Abstract

The low consumption of vegetables in Indonesia and the increasing need for environmentally friendly urban farming solutions are important challenges in realizing a healthy and sustainable diet. Microgreens present an innovative alternative that is not only highly nutritious, but also easy to cultivate at various scales, including in the household environment. This study aims to analyze the nutritional content and bioactive compounds in various types of microgreens and evaluate their health benefits and potential as a functional food source. In addition, this study also illustrates the ease of cultivating microgreens as part of sustainable urban agriculture. The method used was a literature study with a systematic literature review approach of scientific sources published in 2016-2024, such as accredited journals, reference books, and research reports. The results showed that microgreens contain high levels of vitamins, minerals and antioxidants, and have a short harvest period and minimal land requirements. The use of technologies such as LED lighting, suitable growing media and high-quality seeds greatly influence the success of cultivation. Despite challenges in distribution and product durability, microgreens hold promise as a functional food that supports food security, nutrition education and healthy lifestyles in urban areas.
