Brantas River is the largest river in East Java, flowing from the city of Batu upstream until downstream in Surabaya and Sidoarjo. This river plays a crucial role as a vital natural resource that supports the various needs of the surrounding communities. This study serves as a preliminary investigation with the primary aim of assessing the water quality in three different zones of the Brantas River: the upper, middle, and downstream sites. Additionally, this research includes a review to identify the organisms exposed to water pollution in the Brantas River. The study was conducted from November 2020 to April 2023, utilizing an exploratory observational method at 19 observation stations. The data obtained was subsequently analyzed using a descriptive approach. Various parameters were observed, including pH (a measure of acidity or alkalinity), hardness (the concentration of calcium and magnesium ions), alkalinity (the capacity of water to neutralize acids), nitrate, nitrite, fluoride, and heavy metals such as lead (Pb), copper (Cu), and iron (Fe). The research findings indicate that in several upstream areas of the Brantas River, there were elevated hardness, nitrate, lead (Pb), and iron (Fe) that exceeded the established water quality standards. In the middle section of the river, water quality was generally satisfactory, although a few locations exhibited slightly elevated levels of lead (Pb). Meanwhile, all locations downstream of the Brantas River demonstrated water quality that exceeded the prescribed standards. After a literature review, it was discovered that various biota in the Brantas River have been exposed to pollutants, including fish species and plants like Ipomea aquatica and Eichhornia crassipes. Therefore, it is necessary and urgent to improve water management and monitoring plants and biota in the Brantas River to preserve organisms in aquatic and terrestrial ecosystems. Keywords: Brantas river, pollution, water quality

Pepaya (Carica papaya L.) merupakan tanaman hortikultura yang banyak dibudidayakan. Tanaman pepaya sangat digemari dikalangan masyarakat Indonesia. Berdasarkan data Badan Pusat Statistik (BPS) produksi pepaya di Indonesia fluktuatif dari tahun 2012 sampai tahun 2014. Fluktuatifnya produksi pepaya disebabkan kurangnya manajemen lahan di kebun pepaya, penggunaan varietas unggul dan ketersediaan lahan pertanian yang terbatas. Peningkatan produksi pepaya pada setiap kebun dapat dilakukan dengan penerapan teknologi lubang resapan biopori berkompos, dimana lubang biopori akan dikombinasikan dengan bahan organik untuk meningkatkan kualitas lahan dan produktivitas di agroekosistem pepaya yang berkelanjutan. Tahapan pelaksanaan kegiatan tersebut dimulai dari persiapan awal, pelaksanaan kegiatan (sosialisasi dan penerapan Lubang Resapan Biopori Berkompos/ LRBB), monitoring dan evaluasi penerapan LRBB pada kebun pepaya.

The decreasing land area for coffee cultivation in Indonesia has led to a reduction in coffee production. The availability of land with potential for coffee plantation is also decreasing. As a consequence, coffee is cultivated on less fertile lands, such as lands dominated by clay fraction. This land generally has a low pH so that the nutrient content is more absorbed in Al and Fe which react in an acidic environment. Furthermore, heavy texture of soil also inhibits root growth, making it difficult for plants to absorb nutrients. In this study, biopore infiltration holes were used as a solution to improve acidic soil with a dominant clay fraction. The research was conducted at Agrotechnopark Jatikerto, Malang Regency and the soil analysis was conducted at the Soil Chemistry Laboratory, Faculty of Agriculture, University of Brawijaya during 2020-2022. This research was conducted experimentally with a group randomized design. There were four treatments in this study, namely 1) control/no biopore, 2) 30 cm empty biopore, 3) 30 cm biopore + 2.12 kg compost fertilizer, and 4) 30 cm biopore + 1.05 kg goat manure fertilizer. The results showed that biopore infiltration holes added with compost or goat manure fertilizer were able to increase pH, soil organic C, CEC, BS, and total N-P-K nutrients. Furthermore, the increase in organic C and total N-P-K nutrients in the study area was also directly proportional to the increase in chlorophyll content and coffee production. The increase in chlorophyll content and coffee production is a result of the increase in chlorophyll content and coffee yield.

Inceptisol soils mainly have medium to high physical properties. However, these physical properties can be degraded if there is a limiting factor in the terrain, which is the degree of slope and low SOC. On steep slopes, soil infiltration rates decrease, which leads to the limited available soil moisture in root zone subsoil. Application of compost or manure into the soil can improve soil physical properties and increase the soil organic carbon (SOC), it improves soil porosity and improve available water capacity (AWC). This study used the factorial completely randomized design with 8 treatments and 4 replications. The treatments included (Control + Topsoil), (Control + Subsoil), (Compost + Topsoil), (Compost + Subsoil), (Cow manure + Topsoil), (Cow manure + Subsoil), (Goat manure + Topsoil), (Goat manure + Subsoil). The results showed that (1) the addition of compost and manure can improve the physical properties of topsoil and subsoil, reducing macro porosity, increasing meso and microporosity, and increasing field capacity. (2) The addition of compost and manure can increase the water holding capacity of topsoil by 36.72% at 1 MAI to 41.12% at 5 MAI and inceptisol subsoil by 35.27% at 1 MAI to 36.42% at 5 MAI. (3) The addition of compost and manure can increase the C-organic content of topsoil by 1.62% at 1 MAI to 1.72% at 5 MAI and subsoil by 1.24% at 1 MAI to 1.38% at 5 MAI.

Smallholder coffee plantations cover a very large area on inceptisol soil with low productivity; so far, the provision of organic materials in coffee plantations is done by placing it on the surface of the soil so that it is susceptible to loss due to runoff and erosion. This study was conducted by mixing organic materials with topsoil and subsoil to determine their effect on the characteristics of topsoil and subsoil. This study used a Completely Randomized Design (CRD) with 8 treatments and 4 replications. The experimental treatments consisted of P1 (topsoil), P2 (subsoil), P3 (topsoil + Compost); P4 (subsoil + compost); P5 (topsoil + cow manure); P6 (subsoil + cow manure); P7 (topsoil + goat manure); P8 (subsoil + goat manure). The soil was incubated at field capacity conditions for 16 weeks. Soil parameters include: soil pH, soil CEC; soil organic C levels; Ca exchange, Mg exchange, K exchange, and Na exchange. The dose of organic material (cow and goat manure) is 30 tons. ha-1. Providing compost and manure can increase inceptisol soil fertility at the depth of the topsoil and bottom soil (exchangeable K, exchangeable Ca, exchangeable Mg, soil pH, Organic C, and soil CEC levels), this increase is significant compared to the control.

Introduction: This study focuses on the effect of applying clay and compost on improving the quality of sandy soil in terms of the physical and chemical quality of the soil so that it can be a solution to problems in managing sandy soil so that the land can be productive and sustainable. Methods: This study used a factorial completely randomized design (RAL-F) with 3 treatment factors, namely: Depth (K1: 0-30 cm, K2: 30-60 cm), Dosage of compost (M1: 0 ton ha-1 as control, M2: 20 ton ha-1), Percentage of mineral soil (T1: 0% as control, T2: 25%, T3: 50%). Each treatment was repeated 4 times to obtain 48 pot units for the experiment. Data collection is carried out every 2 weeks for soil pH data. As for the other observation parameters taken in the last week of the incubation process, the data taken are chemical data in accordance with predetermined observation parameters which include soil physical properties such as bulk density, specific gravity, porosity, moisture content, pF value and basic chemical properties such as pH, organic matter, P-Available, N-Total. Results: Based on the results of laboratory analysis, it was shown that there was an increase in the average value of pH H2O and pH KCl every week, where initially the pH of H2O was 5.3 (1 MSI) to 5.9 (11 MSI) and the pH of KCl was from 5.1 (1 MSI) to 5.5 (11 MSI). This proves that the addition of organic matter and clay to the soil can increase the soil pH value. In addition to an increase in soil pH, there was also an increase in other chemical properties (BO, total-N and available-P) as well as soil physical properties (BI, BJ, Porosity and pF 2.5). Conclusion: the addition of clay soil and compost can improve the quality of sandy soil, especially the soil chemistry characteristics.

The conversion of agricultural land to non-agricultural uses presents significant challenges to food security, environmental sustainability, and economic progress in Bakalan Village. Food security categories for Bakalan Village conversion farmer families are assessed in this study using System Dynamic and Land Conversion Rate Analysis. A causal loop diagram illustrates the complex relationships between land conversion, food availability, affordability, and needs, crucial for understanding food security dynamics. Higher land conversion rates negatively impact food availability, risking local food security. System Dynamic integrates agricultural and non-agricultural income sources to model food affordability, a key food security determinant. Annual iterations capture fluctuations in land use, income, and food indicators, revealing the evolving impact on food security. This research emphasizes the need for sustainable land use practices, incentivizing land preservation, and promoting diversified incomes to ensure food security, environmental resilience, and socio-economic stability in Bakalan Village and similar agricultural communities globally. Adaptive policies informed by such models are essential for addressing these multifaceted challenges effectively.
