[APPLICATION OF LIQUID ORGANIC FERTILIZER FROM EGGSHELL AND TOFU DREGS ON PROMOTING GROWTH AND YIELD OF LETTUCE UNDER FLOATING RAFT HYDROPONIC SYSTEM]. Eggshell waste and tofu pulp contain nutrients that have the potential as plant fertilizers. The use of liquid organic fertilizer (LOF) from eggshells, and tofu dregs can be a source of nutrition in hydroponic cultivation at a relatively low price. The optimal growth of red lettuce plants requires a proper concentration of nutrients. This study aimed to examine the effect of the concentration of LOF from eggshells and tofu dregs that are most effective in increasing the growth and yield of red lettuce in floating raft cultivation systems. This research was conducted from December 2020 to February 2021 at the Kartini Experimental Garden, Faculty of Agriculture and Business, Satya Wacana Christian University. This study used a Randomized Complete Block Design with liquid organic fertilizer made from egg shells and tofu dregs with different concentrations and AB mix as a comparison. The treatment consists of five levels, namely AB mix, LOF 10 mL/L, LOF 20 mL/L, LOF 30 mL/L, and LOF 40 mL/L. Observation parameters include plant height, number of leaves, leaf area, root length, and fresh and dry weight of the plant. The results of the observations were analyzed using the analysis of variance (F test 5%). On average, the HSD Tukey test followed the treatment with a confidence interval of 5%. This study showed an influence on the treatment of eggshell LOF concentration and tofu dregs 20 mL/L resulting in the highest red lettuce with 9.15 leaves, root length 38.75 cm, header fresh weight 36.33 g and highest root fresh weight 16.22 g at LOF treatment 10 mL/L. These results have not matched the application of ABmix fertilizer, which reached the fresh weight of 74.79 g.

Melon is a fruit plant that has the potential to be developed and can become a superior horticultural product. The demand for melons continuously increases yearly, requiring a large and continuous supply. Fruit must be available at any time in sufficient quantity and quality to be used as an agricultural commodity with high economic value. Diaphania indica (Lepidoptera: Crambidae) is a significant pest that attacks the leaves and fruit of the Cucurbitaceae family, including economically important crops such as melon. Studies on Diaphania pests that attack melon leaves and fruit have not been widely studied in Indonesia. Also, due to the cases happening of leaf and fruit-eating attacks in Bengkulu, proper pest control efforts are needed. One of the basics for determining how to control is to know the population density and the level of damage caused by these pests. This research was conducted on the farmers' land in Sri Kuncoro Village, Pondok Kelapa Sub-District, Bengkulu Tengah Regency, November 2021-January 2022. The variables observed were the population density of D. indica, the percentage of leaf damage, and the percentage of parasitic larvae. The results showed variations in the density of D. indica larvae and the percentage of leaf damage. The mean population density of larvae was 1.47 per plant, and the percentage of infected leaves was 29.49%. Parasitoids associated with D. indica larvae were found in Apanteles spp, with a percentage of parasitized D. indica larvae of 46.67%.
甜瓜是一种极具开发潜力的果树，可以成为优良的园艺产品。对甜瓜的需求每年都在不断增加，需要大量和持续的供应。水果必须在任何时候都有足够的数量和质量，才能作为具有高经济价值的农产品使用。印度裂蝇(鳞翅目:瘿蝇科)是一种重要的害虫，它攻击葫芦科植物的叶子和果实，包括瓜等重要的经济作物。在印度尼西亚，对侵害甜瓜叶片和果实的Diaphania害虫的研究尚未广泛开展。此外，由于在Bengkulu发生的食叶和食果袭击事件，需要采取适当的虫害防治措施。确定如何控制的基础之一是了解这些害虫的种群密度和造成的损害程度。本研究于2021年11月至2022年1月在Bengkulu Tengah reggency Pondok Kelapa街道Sri Kuncoro村的农民土地上进行。观察到的变量是褐家蝇种群密度、叶片损害率和寄生幼虫率。结果表明，不同处理的籼稻幼虫密度和叶片损害率存在差异。幼虫平均种群密度为1.47只/株，染叶率为29.49%。在无翅目蝇中发现了与籼稻幼虫有亲缘关系的拟寄生物，寄生籼稻幼虫的比例为46.67%。

Vermicompost is one of increasingly applied organic fertilizer to many vegetable crops in order to reduce the dependency on synthetic fertilizer, including the use of urea as nitrogen source. This experiment aimed to determine the best dosage combination of vermicompost and synthetic urea on growth and yields of mung bean grown in Ultisols. This experiment was arranged in a randomized complete block design with three replicates. Treatments consisted of (1) control, no urea and no vermicompost, (2) 50 kg/ha urea + no vermicompost, (3) 40 kg/ha urea + 3 Mg/ha vermicompost, (4) 30 kg/ha urea + 6 Mg/ha vermicompost, (5) 20 kg/ha urea + 9 Mg/ha vermicompost, (6) 10 kg/ha urea + 12 Mg/ha vermicompost, and (7) 0 kg/ha urea + 15 Mg/ha vermicompost. Results indicated that the combination of urea and vermicompost increased plant height, leaf number, branch number, number of nodules/plant, shoot to root ratio, number of pods/plant, number of pods/plot, grain dry weight/plant, grain dry weight/plot, and total yield /ha, but not days to flowering and weight of 100 grains. The best combination to increased growth and yields of mung bean was 12 Mg/ha of vermicompost in combination with 10 kg/ha of urea. This combination produced the highest grain yields/ha (2.1 Mg/ha).

Agricultural intensification plays an important role in sustaining productivity. Plastic mulching and the application of pesticides in crop cultivation have become inevitable to achieve high yield production. This study was aimed to determine the effect of plastic mulching and pesticide applications on carbon (C) fractions. The field experiment was designed using a completely randomized design with two factors consisting of plastic mulching and the application of pesticide at two levels (with and without) at each treatment. All the treatments were prepared for three replications. The soil carbon fractions data collected includes active C and humic acid as stable C fractions. The findings of this research showed that both active and stable C fractions were not significantly influenced by plastic mulching and pesticide applications. The active and stable C fractions were ranging from 1.40 to 1.42 g/kg and from 193.3 to 220 g/kg, respectively. These results might be attributed to the period of the study. The duration of this study might be not sufficient to capture any potential long-term changes in soil C fractions induced by the treatments. Thus, further research should consider extending the experiment duration to assess the long-term effects of the agricultural practices to C fractions.

[ISOLATION AND IDENTIFICATION OF STRAWBERRY FRUIT PATHOGENIC FUNGI DURING STORAGE]. Storing strawberry fruit is one way to extend its shelf life and maintain its quality during storage. However, during storage, there is still a risk of pathogenic fungi attack that can cause damage to the strawberry fruit. Pathogenic fungi attack on fruits can cause various types of damage, such as physical damage, color changes, loss of taste and aroma, as well as a decrease in nutritional quality. In addition, pathogenic fungi can also cause significant economic losses for farmers and producers. The purpose of this study is to identify the types of pathogenic fungi commonly found on strawberry fruit and analyze the severity of damage caused by pathogenic fungi. Identification of fungal species is carried out using microscopic methods and through examination of spore morphology. The pathogenic fungi that attack strawberry fruit are Penicillium spp., Colletotrichum spp., and Botrytis cinerea. Strawberry fruit stored at a cool temperature can suppress post-harvest disease symptoms compared to those stored at room temperature.

[NUTRITIONAL CONTENT OF BLACK SOLDIER FLY LARVAE (Hermetia illucensi) FRASS AS ORGANIC FERTILIZER]. Nowadays, maggots or Black Soldier Fly (BSF) larvae are widely used as organic waste decomposers. The use of maggot as a macro-organism waste decomposer is considered an innovation in processing waste. Maggot farming produces residue which is called Black Soldier Fly Larvae Frass (BSFF). BSFF is called organic solid fertilizer and can optimize growth because it contains various nutrient flows needed for plants. Therefore, the objective of this study was to assess the nutritional content of BSF larvae reared in the waste of rice, fruits, vegetables, and their mixture. Within this aim, it was conducted a laboratory experiment using four treatments of BSFF (the waste of rice, fruits, vegetables, and their mixture) research was conducted from March to June 2022 at the Experimental Garden and Integrated Laboratory of Trilogi University, Jakarta, with the Seameo Biotrop Laboratory, Tajur-Bogor, West Java. BSFF nutrient content was measured by the organic fertilizer test kit (PUPO) and standard laboratory procedure. According to the result of the PUPO or laboratory test, it was found that BSFF from organic waste harvested two weeks has fulfilled the standard from Permentan 2019, especially on the treatment of giving waste of rice, vegetables, or fruits with pH criteria between 4-9, C organic more than 15%, ratio C/N less than 25, the total value NPK nutrient more than 2% and Fe was found to be less than 500 mg/kg.
[黑虻幼虫(Hermetia illucensi)草作为有机肥的营养成分]。目前，蛆或黑兵蝇(BSF)幼虫被广泛用作有机废物分解者。利用蛆作为大型生物废物分解者被认为是处理废物的一项创新。蛆养殖产生的残留物被称为黑兵蝇幼虫(BSFF)。BSFF被称为有机固体肥料，可以优化生长，因为它含有植物所需的各种养分流。因此，本研究的目的是评估在水稻、水果、蔬菜及其混合物的废物中饲养的BSF幼虫的营养成分。为实现这一目标，于2022年3月至6月在雅加达Trilogi大学实验园和综合实验室与西爪哇tajul - bogor Seameo Biotrop实验室进行了四种处理BSFF(水稻、水果、蔬菜及其混合物的废物)的实验室试验。采用有机肥检测试剂盒(PUPO)和标准实验室程序测定BSFF的养分含量。根据PUPO或实验室测试结果，发现收获两周的有机废物的BSFF达到了Permentan 2019的标准，特别是对pH值在4-9之间，C有机含量大于15%，C/N比小于25,NPK养分总价值大于2%，铁含量小于500 mg/kg的水稻，蔬菜或水果废物的处理。

Nitrogen is the most often deficient in the soil and will be impacted by farmers associated with the economic issue. Nitrogen exists in soil systems in many forms and changes, such as mineralization and mobilization, nitrification, denitrification, volatilization, runoff and erosion, and leaching. The Inceptisol has a pH of 5,5 (acid), impacting soil nutrients such as nitrogen, phosphor, potassium, and organic-C; meanwhile, Ultisols have high acidity and Al exchangeability. This study aimed to determine the rate of nitrate availability on Ultisols and Inceptisols added dairy cattle waste vermicompost. The experiment was arranged by Randomized Completely Design with two factors. The first factor was vermicompost with three doses; there were 0 ton/h, 15 tosn/ha, and 30 tons/ha and the second factor was two types of soils, Inceptisol and Ultisol. The experiment was conducted by three times. The result is on the R2 value, the reaction order kinetics model, which best explains the relationship between vermicompost dosing and nitrate availability in Ultisols and Inceptisols, is a first-order equation. The constant nitrification rate was 0.04 to 0.06 daily with three dairy cattle waste vermicompost dose levels. The potential nitrification showed that a high-level dose increased high nitrate. In Ultisols, the nitrification potential has risen from 1.21 to 1.44 mg/kg NO3- in others, increasing from 1.36 to 1.41 mg/kg NO3-. Dairy cattle waste vermicompost can accelerate nitrification in acidic soil, especially Ultisols and Inceptisols. This biofertilizer can supply nitrate to the soil by enhancing microbial activity. Nitrate availability in the soil can be supported by 30 tons ha-1 dairy cattle waste vermicompost.
氮是土壤中最常缺乏的元素，并将受到与经济问题相关的农民的影响。氮以多种形式和变化存在于土壤系统中，如矿化和动员、硝化、反硝化、挥发、径流和侵蚀以及淋滤。ineptisol的pH值为5.5(酸性)，影响土壤中的氮、磷、钾和有机碳等养分;同时具有较高的酸性和铝交换性。本研究旨在测定牛粪蚯蚓堆肥中添加多效索和初效索的硝酸盐利用率。试验采用双因素完全随机设计。第一个因素是三剂量的蚯蚓堆肥;分别为0 t /h、15 t /ha和30 t /ha;第二因子为初溶土和终溶土两种土壤类型。实验分三次进行。结果表明，在R2值上，反应级动力学模型是一级方程，该模型最能解释蚯蚓堆肥投加量与Ultisols和ineptisols中硝酸盐有效性之间的关系。在3个奶牛粪蚓堆肥剂量水平下，硝化速率为0.04 ~ 0.06 d。潜在的硝化作用表明，高剂量会增加高硝酸盐。在Ultisols中，硝化潜能从1.21 mg/kg NO3-上升到1.44 mg/kg NO3-，在其他地方从1.36 mg/kg NO3-上升到1.41 mg/kg。奶牛粪蚓堆肥能加速酸性土壤的硝化作用，尤其是长效土和长效土。这种生物肥料可以通过增强微生物活性来向土壤提供硝酸盐。30吨ha-1奶牛粪蚓堆肥可支持土壤硝态氮有效性。
