Abstract

Porang (Amorphophallus muelleri) is a tuber plant that contains the compound of glucomannan which has high economic value with a number of benefits, including as an industrial raw material. The glucomannan content of porang tubers has received special attention in research, including field research to determine soil properties that influence growth and content of gucomannan in porang tubers. A field survey has been carried out to determine the physical properties of soils that influence the glucomannan content of porang tubers grown in four clusters of agroforestry in the dry land of North Lombok, Eastern Indonesia. The results of the research showed that the physical properties of the soil that had a significant effect on the glucomannan content of porang tubers were soil bulk density (BD) with an R2 value of 53.15%, soil porosity with an R2 value of 60.23%, and silt particle fraction with an R2 value of 23. 47%. Thus, managing soil physical properties to facilitate the better quality of porang tubers is necessary.

Abstract

Biochar is recognized as a versatile and sustainable tool for improving agricultural and environmental conditions due to its unique physicochemical properties, such as soil fertility, nutrient retention and water holding capacity. The presence of biochar, which contains stabilized carbon, not only has a positive impact on plant growth and crop yields through microbial activity, but can also act as a sorbent to remove contaminants from soil and water. However, the use of biochar in soil and its effects on ecosystem services depend on several factors. This article explores the impact of biochar use on soil and the potential to address ecosystem service challenges by improving soil composition, increasing access to water, and removing contaminants, all to promote sustainable agriculture. The method of this article consists of a literature review by collecting data from various sources such as scientific journals, books and seminar proceedings. The data obtained were qualitatively analyzed to review and identify the information, resulting in a critical and comprehensive explanation and discussion of the role of biochar in improving soil and environmental quality for environmental services. The results of the literature review are presented in the form of a coherent, systematic and critical narrative. The results of this article review indicate that on-farm biochar application contributes significantly to climate change mitigation through various mechanisms, including biochar's ability to sequester carbon, improve soil quality, and minimize greenhouse gas emissions.

Abstract

Rice plays an important role in meeting carbohydrate requirement and calorie needs to ensure food security. However, in recent years, rice productivity has decreased due to land conversion and climate change such as El Niño. The productivity of drought-resistant rice can be increased through breeding. Genetic diversity and heritability are important genetic parameters in the plant breeding process. Information about genetic diversity and heritability helps determine genetic progress through selection. This research aims to examine the potential genetic diversity and heritability of several mutant lines (M4) of black rice (G10) in order to develop superior rice varieties that are adaptive to dry land. In this research, we used experimental methods using a Randomized Block Design (RBD), calculating the value of the Genetic Diversity Coefficient (GDC) and heritability between quantitative characters. The results of narrow genetic research were found in the characteristics of the number of productive tillers and weight of 100 grains, while high heritability was found in the characters of plant height, moderate heritability was found in the total number of tillers, panicle length, number of empty grains per panicle, and weight of 100 grains. Overall, this research succeeded in identifying mutant lines (M4) of black rice (G10) which have the potential to be developed into superior varieties, especially for cultivation in dry land.

Abstract

There is an increasing rate of land conversion in Indonesia that can threaten food self-sufficiency. Therefore farmers and the government must expand agriculture by developing agriculture on potential available lands such as drylands. However, drylands in Indonesia have low productivity due to low water and nutrient availability. This article aims to determine the potential use of arbuscular mycorrhizal fungi to overcome drought stress and low nutrient availability in drylands. The method used in writing this article is a desk literature study conducted by collecting data from various sources, such as scientific journals, seminar proceedings, and online reports available in related government office in West Nusatenggara Province. The data obtained were then analyzed qualitatively by identifying, reviewing, and synthesizing information to produce a complete and comprehensive explanation. The results of the literature study showed that arbuscular mycorrhizal fungi have the potential to overcome drought stress and low nutrient availability in drylands. The use of arbuscular mycorrhizal fungi can be a sustainable solution to increase agricultural productivity in drylands.

Abstract

The whitefly is a pest that frequently infests cultivated plants, causing both direct and indirect damage that can significantly reduce crop yields. In addition to whitefly infestations, declining soil fertility is another factor that can lead to decreased production. One potential solution to these issues is the use of UV plastic shade. This method can help reduce the population of whitefly pests. This article aims to explore the effectiveness of UV plastic shade in enhancing soil fertility and reducing whitefly presence in arid regions. The research methodology employed is descriptive, utilizing a literature review of sources such as scientific articles, books, journals, discussions, and previous research findings. UV plastic shade has been found to increase the availability of nitrogen and phosphorus in the soil, thereby promoting soil fertility and plant growth. Additionally, UV plastic shade can reduce whitefly populations in dry areas by disrupting their life cycle and behavior.

Abstract

Despite having a considerable potential area, the optimal utilization of dry land is challenging due to the generally low soil moisture content and fertility of dry land in Indonesia. This is evidenced by the intrinsically low organic matter content in dryland soils. Therefore, this article aims to provide information on the potential application of chicken manure to enhance soil fertility and health or to rehabilitate suboptimal dry lands in Indonesia. The methodology used in this article is qualitative, based on a literature review. One approach to improving the condition of dry land in Indonesia is the application of chicken manure, which acts as a soil conditioner and enhances overall soil fertility and health. The results of the study indicate that using chicken manure on dry land can increase crop production, thereby positively correlating with the profits of dry-land farmers.

Abstract

Heavy metal mercury pollution in the environment can have negative impacts on both surrounding ecosystems and human health. Sources of mercury pollution often come from mining activities, particularly from many unlicensed gold mines (PETI) that use the mercury amalgamation method to extract gold. Due to the persistent, bioaccumulative, and toxic nature of mercury, contamination in the soil has increased. One effort to reduce mercury toxicity is the application of absorption methods using phytoremediation plants and compost as regulating factors. The aim of this study is to review sources of information related to the use of phytoremediation plants and the application of compost as remediators to clean mercury (Hg)-contaminated soil. To reduce levels of heavy metal contamination, plants employ five phytoremediation mechanisms: phytoextraction, phytostabilization, rhizofiltration, phyto degradation, and phytovolatilization. Therefore, selecting hyperaccumulator plants that have the ability to accumulate mercury (Hg) at levels 100 times higher than ordinary plants is crucial for effective remediation. Additionally, the use of compost as a source of organic material can enhance mercury mobility. The addition of organic materials such as compost can increase C organic content, cation exchange capacity (CEC), pH, and Hg-chelate formation, thereby maximizing mercury absorption by plants. This combination has a positive impact on reducing mercury levels in the soil and is environmentally safe.

Abstract

Dryland in Indonesia covers approximately 75.6% of the total land area, with a significant portion utilized for agriculture, including maize cultivation. However, the main challenge in maize farming on dryland is the low organic matter content and soil fertility, which can affect growth and yield. This study aims to review various soil tillage techniques and the application of both organic and inorganic fertilizers in maize cultivation on dryland. The soil tillage techniques examined include no-tillage, minimum tillage, and intensive tillage, focusing on fertilization efficiency and the sustainability of land management practices. The methodology employed was a literature review, analyzing publications indexed in SINTA and/or Scopus between 2019 and 2024. The results of the study indicate that the minimum tillage treatment provided the best results, with phosphorus availability of 17.55 mg/kg, potassium of 0.78 cmol/kg, and an increase in organic carbon to 2.44%, along with a slightly alkaline soil pH of 7.65. Minimum tillage was found to be effective in improving soil fertility without causing significant changes in pH, making it the best option for sustainable maize cultivation on dryland.
