Abstract. Raden I, Fathillah SS, Fadli M, Suyadi. 2017. Nutrient content of Liquid Organic Fertilizer (LOF) by various . Inorganic fertilizers have negative impacts on soil structure, cause water and soil pollution, and produce less healthy crop production. These conditions can be improved with organic fertilizers. The research aimed to make liquid organic fertilizer (LOF) treated with various bio-activator and soaking time and to know the nutritional content in it as well. Observed variables were pH; C/N ratio; macro and micro nutrients. Research used a completely randomized design in factorial analysis. The first factor was the various bio-activator (b), i.e. b1 = EM-4 culture; b2 = boisca; and b3 = shrimp paste. The second factor was soaking time (t), i.e. t1 = 10 days; t2 = 20 days, t3 = 30 days; and t4 = 40 days. The treatment was repeated (r) three times and tested by analysis of variance and LSD at 5% level. The results showed that culture of EM4 bio-activator had higher content of C/N ratio; organic-C; total-N; Co; B; Mn; Fe; Cu; and Zn than the other bio-activators, although it also had lower content of pH, P 2 O 5 ; K 2 O than others but those values were not significantly different compared to boisca and shrimp paste bio-activators. The other result showed that soaking time had significantly effect in determining the nutrient content of the C/N ratio; Organic-C; Total-N; P 2 O 5 ; K 2 O; Total-Ca; Mg; S; Co; B; Mn; Fe; Cu; and Zn, but not at pH variable. Soaking time of 40 days (t4) provided the highest value on the C/N ratio; pH; Mn; Fe; and Zn. On the other hand, soaking time of 30 days (t3) provided the highest value on the organic-C; K 2 O; total-Ca; and B. Meanwhile, soaking time of 20 days (t2) provided the highest nutrient values on Cu; Co; B; Mg; and total-N. While, soaking time of 10 days (t1) gave the highest value on the nutrient content of P 2 O 5 and S. The interaction between the various bio-activator and soaking time b3t3 had the highest value 575.41 ppm of B, then treatment b2t3 had the highest 0.89% of K 2 O, and treatment b1t4 gave the highest nutrient content 1648.82 ppm of Fe.

“…A study conducted by Hernandez et al (2014), showed the lower yields observed in the soils treated only with compost is probably due to nutrient limitation, mainly N. Combination use of organic and mineral fertilization improved the effect on yield compared to the use of mineral fertilization alone, although differences were not always statistically significant. Another study conducted by Adil et al (2006) showed that tomato fertilized with compost alone or in combination with urea resulted in significant total fruits than those control. A further study such as nutrient analysis on kangkung biomass and tomato fruit to determine the effect of various type of compost on nutrient content has to be done towards the organic farming (Figure 4).…”

The study was conducted to develop local fruit plants and to improve vegetable production at the Plant Germplasm Garden of RC for Biotechnology-LIPI. Carambola (Averrhoa carambola), durian (Durio zibethinus) and guava (Psidium guajava) were propagated vegetatively (grafting and budding) and were grown on the media containing grass compost (K-1), spent compost of paddy straw mushroom (K-2) or oyster mushroom (K-3) in combination with rootstock length of 45-55 cm (TB-1), 65-75 cm (TB-2) and 75-90 cm (TB-3). Tomato (Lycopersicum esculentum) and kangkung (Ipomoea reptans) were grown on the same media in the screen house. The highest survival rate of grafted durian (71.56%) was obtained from TB-3 grown on K-1 by budding technique. Meanwhile, the highest survival rate of carambola (68.89%) was obtained from TB-1 by grafting technique. The budding technique was not appropriate for guava (0 % of survival). Application of K-3 of 3 kgs on tomato plants resulted in the highest fresh weight, length, and diameter of the fruit, and the highest of plant height, total leaves, and biomass of kangkung. The study is expected to be applied to improve fruit plant growth and survival rate as well as a high production of organic vegetable.

“…Not only is this productivity often short-lived, but the consistent use of chemicals such as these threaten the health of farmers and ultimately, the health of the surrounding ecosystem [66,67]. The prolonged use of chemical fertilizers changes the pH of soil, causing it to become too acidic, and can also impair soil fertility [68,69]. The reversal of soil acidification and restoration of soil fertility is possible through the use of natural fertilizers [68] but requires not only the commitment of the farmer/s in question, but every farmer in the area due to the possibility of run-off.…”

There is an urgent need for a global transition to sustainable and wildlife-friendly farming systems that provide social and economic equity and protect ecosystem services on which agriculture depends. Java is home to 60% of Indonesia’s population and harbors many endemic species; thus, managing agriculture alongside human well-being and biodiversity is vital. Within a community of ~400 coffee farmers in the province of West Java, we assessed the steps to develop a wildlife-friendly program until reaching certification between February 2019 and October 2020. We adopted an adaptive management approach that included developing common objectives through a process of stakeholder consultation and co-learning. We firstly investigated via interviews the expectations and the issues encountered by 25 farmers who converted to organic production in 2016. Their main expectations were an increase in income and an increase in coffee quality, while they had issues mainly in finding high quality fertilizers, reducing pests, and increasing productivity. We used this information to establish a problem-solving plan for the transition to community-wide wildlife-friendly practices. As part of the adaptive evaluation, we assessed the quality of coffee plantations before and after the implementation of coproduced actions. The quality of coffee significantly improved after our interventions to reduce the coffee berry borer, especially in the fields that started as inorganic and converted to organic. We uncovered additional issues to meet the standards for certification, including banning hunting and trapping activities and increasing coffee quality for international export. We describe the coproduced actions (agroforestry, conservation education, local law, organic alternatives) and phases of the program and discuss the potential barriers. We provide novel evidence of adaptive management framework successfully used to implement management actions and reach shared goals.
