Abstract

Sustainable agriculture is not only limited to eliminating the use of agricultural inputs in the form of inorganic substances but in the form of utilizing local natural resources. The use of vermicompost and refugia plants is an alternative in organic farming. The purpose of this study was to determine the use of vermicomposts and refugia plants as inputs for organic farming in lowland rice. The study was carried out on a paddy pond in the village of Kuluran, Kali Tengah, Lamongan. The study used a randomized block design with treatment giving 20 tons ha-1 kascing and refugia plants on (P0) without chemical fertilizers, (P1) with the addition of 562.5 kg ha-1 NPK, (P2) adding 375.0 kg ha-1 NPK, (P3) addition of 187.5 kg ha-1 of NPK and (P4) addition of 750.0 kg ha-1 of NPK. All treatments were repeated 3 times. The results showed that the application of vermicompost treatment of 20 tons ha-1 and refugia plants without organic fertilizer gave the highest yield at the final plant height (118.61, cm) and the production of wet rice (13.28 tons ha-1).

Abstract

With the large need for organic fertilizer in fulfilling agricultural cultivation, vermicompost is a fast and appropriate way to utilize local natural resources in meeting the needs of organic biological agents. This study aims to determine the effect of giving organic fertilizer kascing with biological dimensions and chemical fertilizers (Urea, KCl, KNO3 Merah, and Phonska) with indicators of shallot plants. The study was conducted using a randomized block design, with the treatment of giving biological fertilizer with a dose of 30 tons/ha combined with chemical fertilizer with a dose (Urea 200 tons/ha; KCl 200 tons/ha; red KNO3 200 tons/ha, and Phonska 200 tons / ha Ha). The treatments P0 (without chemical fertilizer), P1 (25% of the dose of chemical fertilizer), P2 (50% of the dose of chemical fertilizer), P3 (75% of the dose of chemical fertilizer) and P4 (100% of the dose of chemical fertilizer). The results showed the availability of P-soil and C-organic soil after treatment were not significantly different. Observation of plant height also shows unreal results. While the number of tubers and production results obtained P2 gives the highest yield and is significantly different from other treatments.

Abstract

This area is a mangrove forest with a natural and high plant density. The existence of mangrove forest tourism activities allows human intervention in mangrove habitat, which will have an impact on carbon storage in the soil. This research aims to determine the carbon stock in the soil in the mangrove area of Wonorejo, Surabaya. The study was conducted by surveying the land by dividing the mangrove forest land into 4 zones based on a perpendicular coastline. Environmental observations include the number of plants and the physical and chemical characteristics of the soil. The results showed that the mangroves of the Avecennia family dominated the near-shore zone and the mangroves of the Rhizophora family dominated zones 3 and 4. The growth diversity of mangroves tended to be low in each plant family, while in each zone the diversity of mangroves was at moderate levels. In soil characteristics, the texture tends to be dusty and dusty clay, with high pH, EC and Redox values. The results of the measurement of carbon stocks in the mangrove forest area ranged from 1.04 to 1.45 Mg Ha-1.

Abstract

Marginal soil is infertile soil caused by various factors, one of which is the excessive accumulation of heavy metals. FOBIO microorganism-based biopesticide formula containing phosphate solubilizing bacteria is expected to be used to reduce excess heavy metals in the soil. Brasica rapa L. is a variety resistant to Pb heavy metal stress and absorbs more heavy metals into root tissue than leaf tissue with the help of microorganisms. This study aimed to determine the combination of Brassica rapa L. and FOBIO biopesticide in absorbing Pb in the soil, determine the growth of Brassica rapa L. at each Pb concentration, and determine the population of phosphate-solubilizing bacteria in the soil at each level of Pb stress after remediation. This study used variations in the concentration of heavy metals, particularly Pb. Parameters observed included plant growth, Pb concentration in the soil before and after remediation, and the population of phosphate-solubilizing bacteria. The results showed that combining FOBIO biopesticides and Brassica rapa L. could reduce Pb concentration in the soil. The growth of Brassica rapa L. plants was significantly different after treatment. The findings confirmed that increasing, the concentration of Pb led to a decrease in the population of phosphate-solubilizing bacteria.

Abstract

Porang (Amorphophallus oncophyllus L.) stands as a prominent agricultural product in Indonesia. As the demand for porang continues to grow, it becomes crucial to balance it with the expansion of suitable land for cultivation. The selection of appropriate land for crop planting requires a thorough analysis of land feasibility, commonly known as land suitability assessment. This study aims to evaluate land feasibility, identify limiting factors, and explore potential solutions for sustainable cultivation of porang in Sumberejo Village, Pasuruan, East Java. The research was employed by a matching method for land suitability assessment based on climatic, physical, and chemical data. The development of a land suitability map was achieved through the overlay of various stages using land characteristic information. The findings reveal that the residents' lands fall within the actual land classes of S3 (suitable marginal) and N (not suitable), with base saturation (nr3) and slope (eh) identified as the primary limiting factors. To improve the suitability of the selected lands, several recommendations were proposed, including the implementation of cover crops, terracing practices, and the addition of potassium-rich organic matter derived from bamboo waste. These recommendations have the potential to elevate the land class to S2 (suitable) and S3 (suitable marginal), thereby addressing the identified limitations and promoting sustainable porang cultivation.

Abstract

This thesis presents a research study utilizing a case study approach, with a qualitative methodology employed. The focus of the research is on the model, process, facilitators, and barriers of Qiroah Muwahadah learning in maintaining the fluency of Quranic recitation at Pondok Pesantren Madrasatul Quran. Data collection methods included observation, interviews, and documentation. The analysis revealed that K.H. Yusuf Masyhar utilized a systematic and classical learning model in providing Quranic guidance to the students, grouping them during recitation, fashohah, and group mudarosah sessions according to their reading and memorization abilities, yielding results in line with expectations. Many graduates from the pondok have become influential figures in society due to their proficiency in Quranic recitation. Supporting factors in this learning process include the alumni and graduates' desire to preserve Qiroah Muwahadah, strong bonds among alumni in supporting the pondok's programs, community trust in the pondok's reputation, and the high motivation of the students studying there. However, obstacles to the implementation of this learning process include differences in learning reception, the absence of prominent Qiro’ah Muwahhadah figures today, the variety of preferred recitation styles among students, challenges in program execution, and insufficient attention from management to the importance of maintaining the recognized quality of Quranic recitation fluency.

Abstract

Soil physical properties are those soil properties that affect plant growth and production, determining root penetration into the soil, soil water-holding capacity, drainage, soil aeration, and soil nutrient availability. Shallots prefer fertile soil, loose, and rich in organic matter. Loose and fertile soil produces large tubers. This research was conducted to determine and study the physical properties of the soil on shallots in Kecamatan Gondang, Nganjuk and Kecamatan Kedungadem, Bojonegoro. Undisturbed and disturbed soil samples were taken at depths of 0-20 cm and 20-40 cm. Determination of the sampling point using the Purposive Random Sampling method based on the type of soil and land use as well as surveying the location of observations. The selected soil types are Vertisols and Inceptisols. Each soil type is represented by 3 sampling points. The results showed that the physical properties of the various shallot fields studied had a soil texture dominated by clay and silt with a silty clay texture class, moderate bulk density, good soil porosity, soil permeability has various classifications from slow to fast, very stable. aggregate stability, and has low C-Organic material. Several parameters of the physical properties of the soil are suitable for growing shallots. However, the C-Organic content is still in the low category and it cannot meet the need for organic matter for shallot cultivation.Key words : soil physical, shallot, Vertisols, Inceptisols

Abstract

Forests are a store of carbon stocks, carbon is transferred from the atmosphere into the plant body through the process of photosynthesis. The occurrence of land conversion and land cover changes can cause the loss of carbon stocks, causing global warming. This study aims to identify changes in carbon stocks (C) due to land use change, as well as carbon emissions caused by the use of industrial forest land, dry land, and horticultural land in Bontang City, the part of East Borneo. Carbon stock in land consists of several components, namely soil carbon, top plant carbon, bottom plant carbon, litter carbon, and necromass carbon. The measurement results show that the largest carbon stock value is found in industrial forest land type 2 with a value of 158.54ton/ha. Carbon emissions occurred in the period 2009 to 2016 on forest land that was turned into type 1 industrial forest land, moor, and horticulture. The carbon emission that occurs is 34.09kton.

Abstract

Land use planning must be designed in such a way that the actual rate of soil erosion remains below the permitted erosion threshold. Wonosalam, a sub-district in Jombang Regency, East Java, is characterized by a topography with elevations ranging from 500–600 meters above sea level and predominantly steep to very steep slopes. To estimate erosion rates in this area, the Universal Soil Loss Equation (USLE) method is applied. Based on the erosion rates calculated for various slope units, suitable land management strategies are proposed to reduce soil loss. These strategies are designed to ensure erosion rates do not exceed the tolerable limit. At SPL K3, the erosion rate is already within the allowable limit; however, the planting of Crotalaria is recommended to maintain erosion at 16.1 tons/ha/year. For SPL T1, T2, and T3, the addition of permanent, dense, strip grass barriers and contour planting is advised. At SPL S1, applying 3 tons/ha/year of mulch and implementing contour planting can reduce the erosion rate to 9.6 tons/ha/year. In contrast, erosion rates at SPL Kebun 3, Tegalan 1–3, and Sawah 1 exceed the permissible limit, prompting the need for specific land management interventions. Conservation priorities are established using a scale-based approach, identifying moorlands as the top priority for rehabilitation. Conservation measures include both vegetative and mechanical approaches, such as constructing bench terraces and planting economically valuable crops suited to local conditions—namely coffee and durian—to support sustainable land use and community livelihoods in Wonosalam.
