Fertilization activities also provide macro and micro-nutrients for plants such as nitrogen, phosphorus, and potassium. The role of the three elements is very important and have mutually supporting functions in plant growth and development. This research aims to observe the effect of different doses of liquid organic fertilizer on the growth of lettuce plants. So, we can provide the best advice for fertilizing lettuce plants. Providing liquid organic fertilizer to 20 lettuce plants using 3 doses mixed with 1000 ml of water for each dose, including: (1) 5 ml dose of liquid organic fertilizer + 1000 ml water for five plants, (2) 10 ml dose of liquid organic fertilizer + 1000 ml of water for five plants, (3) Dose of 15 ml of liquid organic fertilizer + 1000 ml of water for five plants, and (4) Use of control on five plants that were not given POC. The results of the research showed that the effect of giving each dose of liquid organic fertilizer, namely 5 ml, 10 ml and 15 ml, showed the highest growth results, namely at a dose of 15 ml and the lowest was obtained in the treatment without liquid organic fertilizer (control).

This research aims to identify potential types of pests that attack horticultural plants at the Agricultural Extension Center (BPP) of Ngingas Village, Krian District, Sidoarjo Regency. This research uses a qualitative descriptive method by collecting data through direct observation, interviews with farmers and BPP staff. The types of plants that are the focus of this research are chilies, tomatoes and eggplant. The research results show that there are three main types of pests that attack horticultural plants in the area, namely whiteflies (Bemisia tabaci), mealybugs (Phenacoccus manihoti), and fruit flies (Bactrocera spp.). Symptoms of whitefly infestation include yellowing leaves and growth of sooty mold due to honeydew excretion. Mealybugs cause leaves to curl and turn yellow with white powder on the undersides of the leaves and stems. Fruit flies cause holes in the fruit, turning brownish in color, and the presence of larvae in the fruit.

Soil characteristic and properties are essential determinants for effective land management. Soil genesis results from the interaction of various pedogenic factors, which are influenced by environmental conditions, thereby producing diverse soil types in different locations. This study was conducted in the Wonosalam sub-district, an area characterized by diverse regional conditions due to its varied physiographic features. The physiographic and climatic conditions in this region significantly influence soil formation processes. This research focused on monitoring soil development at several locations within Wonosalam, specifically at the UPN "Veteran" Jawa Timur experimental field. The study included five observation points, categorized by land map units: PW1, PW2, PW3, PW4, and PW5. Morphological analyses indicate the presence of two distinct soil types among the five observation points. The soils in PW1, PW2, PW3, and PW4 are classified under the Alfisols order, specifically within the Typic Hapludalf subgroup. In contrast, the soil at PW5 belongs to the Inceptisols order, specifically the Typic Humudepts subgroup. This diversity suggests that the area encompasses soils of different orders. The soil characteristic data obtained from the UPN "Veteran" Jawa Timur experimental field can be utilized as a basis for planning the management of the area.

Grass jelly is a popular plant in Indonesia. Various kinds of culinary preparations from grass jelly are developing in society. The benefits of grass jelly are very good for digestion, blood sugar, and preventing cancer. Grass jelly can be cultivated in narrow areas using polybags or pots. This method is a way that can be used to carry out agricultural activities in urban environments. The problem of narrow land can be handled by planting in containers and using ready-to-use media. This activity was carried out at RW IX, Griya Bhayangkara, Sidoarjo, East Java. The aim of this activity is to introduce the importance of PKK groups in urban areas to develop grass jelly plants because the benefits are very good and can be processed on a household scale. The methods used are lectures and practice. The type of grass jelly being developed is green grass jelly. According to the PKK group, grass jelly plants are very interesting to develop and have many benefits. For this reason, grass jelly plants are distributed to be cared for and harvested so they can be processed into various foods.

Heavy metal contamination in urban coastal areas poses a serious environmental threat, with lead (Pb) being one of the most persistent and hazardous pollutants. Mangrove forests, which act as natural buffers between land and sea, have the potential to mitigate heavy metal pollution through phytoremediation. This study evaluates the phytoremediation potential of three mangrove species—Avicennia marina, Rhizophora mucronata, and Bruguiera gymnorrhiza—in lead-contaminated coastal areas of Wonorejo and Gunung Anyar, Surabaya, Indonesia. Sediment, root, and leaf samples were collected using a survey method and purposive random sampling. Physiochemical analysis included soil texture, pH, electrical conductivity (EC), and Pb concentration. Pb levels in Gunung Anyar sediments reached 12.0 ppm, higher than Wonorejo’s 4.05 ppm. A. marina exhibited the highest Pb accumulation, with a bioconcentration factor (BCF) of 8.85 in roots and 6.97 in leaves. R. mucronata had a BCF of 5.75 in roots and 2.09 in leaves, while B. gymnorrhiza demonstrated a root BCF of 28.8 and leaf BCF of 28.4. Translocation factor (TF) analysis revealed that A. marina had the highest TF (1.27), indicating phytostabilization as its primary mechanism. Meanwhile, R. mucronata and B. gymnorrhiza exhibited phytoextraction characteristics due to higher metal translocation efficiency. These findings highlight the distinct phytoremediation strategies among species.

The Lapindo mud disaster in Porong, Sidoarjo, Indonesia, resulted from mining activities, leading to severe iron (Fe) contamination in the soil. This contamination has adversely impacted agricultural productivity in the affected areas. Phytoremediation, utilizing humic acid as a chelating agent and hyperaccumulator grasses, is a potential solution to mitigate this pollution. This study employed a factorial completely randomized design (CRD) to evaluate this approach with two factors: the application of 600 ppm humic acid and the use of different grasses (vetiver, elephant grass, nutgrass, and gotu kola). Observed parameters included plant dry weight and total iron content in soil and plant tissues. These data were used to determine the bioconcentration factor (BCF), translocation factor (TF), and absorption efficiency (%). The results indicated that humic acid significantly increased plant dry weight and iron uptake in plant tissues. The combination of gotu kola and humic acid showed the highest phytoremediation potential, with a BCF of 0.3121, TF of 1.4871, and an absorption efficiency of 55.7538%. This study highlights the effectiveness of humic acid and hyperaccumulator grasses in phytoremediation of iron-contaminated soils, offering a sustainable approach to improving soil health and agricultural productivity in polluted areas.
