The results showed that the concentration treatment of liquid organic fertilizer made from gamal leaves had a real influence on the increase in height, stem diameter and number of leaves in arabica coffee seedlings. The best treatment in this study was 40% concentration treatment (P3) with an average seedling height of 15.27 cm, an average seedling stem diameter of 3.17 mm and an average number of seedling leaves of 12.28 strands and the results of BNJ fingerprint analysis with an average height of 5.59 cm, number of leaves of 1.2 strands and stem diameter of 0.88 mm.

Effect of Concentration of Liquid Organic Fertilizer and Arbuscular Mycorrhizal Fungi (CMA) on Growth and Red Bean Plant (Phaseolus vulgaris L)

This study aims to determine the interaction between the effect of liquid organic fertilizer concentration and arbuscular mycorrhizal fungi (CMA) on the growth and yield of red bean plants (Phaseolus vulgaris L.). The experiment was conducted in Nusaherang Village, Nusaherang District, Kuningan Regency, from July to September 2022. The research method used is the experimental method of Group Random Design (RAK) factorial pattern. The treatment consists of two factors and is repeated three times. The first factor is the concentration of liquid organic fertilizer (P), which consists of three levels, namely: P1 (5 ml / l), P2 (10 ml / l), and P3 (15 ml / l). The second factor of arbuscular mycorrhizal fungi (C) consists of three levels, namely: C1 (5 g / plant), C2 (10 g / plant), and C3 (15 g / plant). The primary observation data is processed using variance analysis; if there is a noticeable effect, the test is continued with the Duncan multiple distance test. The results showed a real interaction between the concentration of liquid organic fertilizer and arbuscular mycorrhizal fungi on plant height aged 21 HST, root length aged 21 HST, number of flowers aged 35 HST, and number of pods per red bean plant. The concentration treatment of liquid organic fertilizer has an independent effect on the number of leaves aged 21 HST. In comparison, the treatment of arbuscular mycorrhizal fungi has an independent effect on the number of leaves aged 21 and 28 HST and the number of seeds per pod. The treatment of liquid organic fertilizer and arbuscular mycorrhizal fungi has the same effect on yield variables, so the average weight of fresh red bean beans per plot is 626 g (0.63 kg) or equivalent to 1.6 tons/ha, assuming 80% of the land is effective.

ANALISIS KANDUNGAN UNSUR HARA PUPUK ORGANIK CAIR DARI KOTORAN SAPI DAN DAUN Pueraria javanica

Cow dung and leaves of Pueraria javanica are organic wastes that highly available and content nutrients.

Pertanian Organik sebagai Alternatif Teknologi Agrowisata di Sembalun Lawang

Indonesia is an agrarian country with a tropical climate and has abundant resource potential in the form of various agricultural commodities. Sembalun lawang is one of the villages located in Sembalun District with a population in 2021 of 4,985 people, where most of the population has a livelihood as farmers. One of the attractions of Sembalun Lawang Village for tourists lies in the agricultural sector, so agrotourism in this area must be improved. The implementation methods used are observation, experimental, and socialization. Observations made in Sembalun Lawang Village showed that the majority of farmers still did not apply organic farming in farming and depended on the use of chemicals, so thematic KKN students conducted experiments to test the growth of pakcoy plants that had been given liquid organic fertilizer treatment. Socialization is carried out to the community to educate about the dangers of using synthetic chemicals and introduce organic farming that is more environmentally friendly
