Abstract

Changes in natural resources have presented major problems for farming communities in rural areas. In general, farmers diversify their livelihoods in the non-agricultural sector without paying attention to the impact on the availability of natural resources in the future. Sand mining activity has become one of the short-term solutions for farming communities in rural areas. As a result, a problem such as land degradation occurs in the village, thereby generating negative impacts on the availability of nature for the next generation. This study aimed to analyze the causes of land degradation and describe the Integrated Farming System (IFS) as a solution to address the land degradation problem in Bambang Village, Wajak District, Malang Regency. This study applied a qualitative case study research design, and the research methods included in-depth interviews with 40 informants, observation, and Focus Group Discussion (FGD). The location of this study was determined by purposive sampling, considering that Bambang Village is one of the villages affected by land degradation due to sand mining. The results of the study revealed that land degradation was due to the vulnerability of the farming community; thus, another alternative was proposed to utilize part of the land (20%) as a sand mining area without neglecting environmental preservation as a reward for environmental services. In addition, IFS and the actors as ecopreneurs were considered as alternative solutions to meet the needs and to prepare the farming community resilience through ecological preservation by sustaining the ecosystem balance. In practice, IFS requires integration among stakeholders, farmers and concerned institutions.

Abstract

Rice grains produced in the conventional system are a prime source of heavy metal exposure in the human body leading to various health problems. The objective of this study was to assess heavy metals concentration in soil and rice grain under the conventional rice farming system in Banyumas, Indonesia, the pollution index, and the bioaccumulation factor. There were thirty-seven samples collected based on soil type, elevation, and irrigation system. The heavy metals level in soil ranged from 2.7 to 39.92 ppm of Pb, 0.11 to 3.01 ppm of Cd, and 4.79 to 61.32 ppm of Cr. Pb and Cr accumulation levels were below the maximum permissible concentration (MPC). A different result in Cd exceeded the MPC in 56.75% of sampling sites. Rice grain showed a high accumulation in Pb (6.85 ppm) and Cr (5.73 ppm) that exceeds the maximum standard. Cd exceeded 24.32% of sampling sites with an average of 0.54 ppm. The Pollution Index (PI) was medium in Cd and low in Pb and Cr. The Bioaccumulation Factor (BAF) of heavy metals in rice was Cd>Pb>Cr with averages of 0.64, 0.53, and 0.30, respectively. A high correlation resulted in Pb and Cd in soils and rice grains. Remediation is must done to reduce the heavy metals accumulation in soils and rice grains for environmental and health safety to prevent further contamination.

Abstract

The Suluh river basin is subjected to soil erosion due to land use and land cover change. Yet, the impact of land use/land cover change soil erosion has not been applied in the study area. Thus, the current study focused on the modeling of the impact of land use/land cover changes on soil erosion in the Suluh river basin, the northern highland part of Ethiopia. Landsat image data sources were used to achieve the objectives. Ancillary data was also used. The nearest neighbor's fuzzy way of classification and the land change modeler for modeling, and the revised universal soil loss equation model for estimating the soil erosion rate were employed. Both qualitative and quantitative data were analyzed qualitatively and quantitatively. The study's findings confirmed that cultivated land, bare land, and built-up areas significantly increased while areas occupied by natural vegetation such as forest land, shrub lands, and grazing lands decreased at a rapid rate in between 1990 to 2018. The predicted results suggest the continuation of the trend up to 2048 if business as usual is continued. The annual mean of soil lost in the study area was about 36.31, 43.32, and 47.78 in the years 1990, 2002, 2018, and will be 56.54, and 71.62 tons per hectare per year in 2028, and 2048, respectively. When we consider 15 t ha−1 year−1 as the maximum tolerable soil loss (TSL) rate for ease of presentation, the areas above the TSL have increased from 88.3% in 1990 to 88.6% in 2002 and to 89.6% in 2018, and are expected to increase to 89.9% and 99.8% in 2028 and 2048 periods, respectively. Thus, land use and land cover change information and its impact on soil erosion should be taken under consideration by land use planners to apply sustainable land management activities in the Suluh river basin.

Abstract

Archipelago areas have high marine tourism resource potential, so they are often exploited for tourism needs. The characteristics of the Labuan Bajo region in the form of islands with geomorphological conditions in the form of hills have the potential to reduce the carrying capacity of the environment. Regional development in Labuan Bajo, classified as a semi-arid area for tourism purposes, can potentially cause a clean water crisis. This study aimed to analyze the environmental carrying capacity related to water availability to support the development of the Labuan Bajo region to become a super-priority tourism destination. The research method used is quantitative in the form of spatial analysis, literature studies, and water-carrying capacity analysis based on the Decree of the Minister of Environment and Forestry No. 297 of 2019. The research data were obtained from field observations and government agencies. The results show that the carrying capacity of water in 56.87% of the area in West Manggarai Regency has a deficit status. Most areas experiencing a deficit are on the mainland of Flores Island, especially in the urban area of Labuan Bajo. This is due to low rainfall, low soil ability to absorb water, and high anthropogenic activity from both local residents and tourism activities. In addition, the content of salinity, detergent, and BOD (biological oxygen demand) in groundwater samples in the urban area of Labuan Bajo has exceeded the water quality standard threshold. The results of this study can be considered for policy directions related to land use for regional development in semi-arid island areas.

Abstract

Utilization of ex-sand pit lakes for aquaculture is difficult due to low water quality and high concentrations of iron (Fe). Phytoremediation using aquatic plants has been proven to be effective in reducing Fe in waters. This study aims to determine the growth, feed conversion efficiency and survival rate of tilapia (Oreochromis niloticus) cultured with ex-sand mining water media with phytoremediation treatment. Phytoremediation treatment was carried out by Eichhornnia crassipes, Azolla pinnata, and Salvinia molesta. Fish culture experiments were carried out in plastic tarpaulin tanks for 40 days, with ad satiation feeding, three times a day using the commercial feed. The results showed that phytoremediation with aquatic plants had succeeded in reducing Fe to a level suitable for fish culture. Fish culture experiments showed an absolute length growth rate of 0.09-0.18 cm/day and an absolute weight growth rate of 0.11-0.16 g/day. The feed conversion ratio was 1.18-1.40 and the survival rate was 98.04-99.08%. The survival rate of tilapia is high, the feed conversion ratio is medium and growth is low. The high environmental temperature and the decrease in water quality due to the absence of water changes and aeration are suspected of causing the low growth of fish. Therefore, further research with water change and aeration experiments and the use of other species of fish is needed to follow up the results of this study.

Abstract

Tailing post-tin mining land has a sandy textured and loose structure. Those physical properties can affect the efficiency of fertilization and cause inefficiency of nutrient absorption in plants. That issue can be corrected by the application of organic material such as cow manure compost which has the potential for plant cultivation, especially for “porang” (Amorphaphillus oncophyllus Prain). This study aimed to examine the cultivation of porang plants in post-tin mining tailings by applying cow manure compost and to determine the best dose of cow manure compost for porang cultivation in artificial ex-tin mining land. This study used a single-group randomized design method with the treatment factor being the dose of cow manure compost consisting of five dose levels (5 t ha-1, 10 t ha-1, 15 t ha-1, 20 t ha-1, and 25 t ha-1). Each treatment level was replicated with five replications, and each replication consisted of five populations so the total population was 125 plants. The results showed that the application of various doses of cow manure compost to artificial post-tin mining land affected the growth and yield of porang plants. The treatment of cow manure compost at a dose of 25 t ha-1 gave the best growth and yield of porang plants. Heavy metal (Pb) analysis on porang tubers showed that all doses of cow manure compost had a Pb content value of <0.059%, which means that cow manure compost can reduce heavy metal uptake in porang tubers. Porang planted in artificial post-tin mining land is safe for consumption because lead (Pb) content was below the threshold of Indonesia National Standard (SNI) for food.

Abstract

This study aimed to screen some potential local seed grains for hydroseeding and describe their characteristics based on the literature review and a year of hydroseeding application. This study used six species/variants of Poaceae (Coix lacryma-jobi, Eleusine indica, Setaria italica (brown, black, and red), Sorghum timorense, S. bicolor, Themeda arundinaceae), five species of Leguminosae (Adenanthera pavonina, Cajanus cajan, Sesbania grandiflora, S. sesban, Indigofera sp.), a species of Cyperaceae (Cyperus javanicus), Sapindaceae (Sapindus rarak), Rhamnaceae (Ziziphus jujuba), and Moringaceae (Moringa oleifera). A seed germination test was held using soil media placed in 5 pots per species until 15 days after sowing (DAS). Characters were scored, and data were statistically analyzed. A field record of one-year hydroseeding applied on 6 m x 6 m post-coal mining land plot was presented. Some data such as pH H2O, pH KCl, conductivity, and soil organic carbon among hydroseeding areas, unrevegetated areas, and reference sites were observed. Results showed that there were 13 of 17 species could variably germinate. The fastest germination time was recorded for S. timorense, S. bicolor, red S. italica, C. cajan, and S. grandiflora, while the highest germination rate (≥50%) was black S. italica (80%), brown S. italica (58%) and S. bicolor (50%). The annual black and brown S. italica, S. bicolor, and S. timorense were highly recommended to be used in hydroseeding. The perennial C. cajan, Indigofera sp., S. sesban, and T. arundinaceae were also potential to be added into a hydroseeding slurry to improve pioneer vegetation multilayering structure and diversity.

Abstract

Temulawak or Javanese turmeric (Curcuma xanthorrizha Roxb.) has great adaptability and is tolerant of low light intensity; therefore, it may be planted on calcareous soil under teak stands. However, temulawak may thrive in soils with a pH of 5.0-6.5 and plenty of organic matter. Calcareous or alkaline soils have problems with high pH and low organic matter. These conditions can be improved with soil amendments. Manure and other soil amendments can remedy soil structure, chemistry, and organisms. Sulfur is generally used to lower soil pH. Sulfur is a structural component of several coenzymes, chloroplasts, and vitamins essential for plant metabolism. This study aimed to elucidate the effect of manure and sulfur fertilizer on temulawak yield and quality grown on calcareous soil beneath teak stands. This study used a completely randomized block design with two factors: manure doses of 10, 15, and 20 t ha-1 and ZA doses of 0, 40, 80, and 120 kg ha-1. According to the findings, the soil pH to increase the rhizome’s fresh weight per clump is between 5.72 and 6.00. In terms of curcuminoid content and antioxidant activity, the soil pH required by temulawak ranges from 5.94 to 6.61.

Abstract

Brebes Regency, Central Java, is one of Indonesia's most important shallot production center implementing intensive agriculture. In the bulb production, K is needed more than other nutrients. This study aimed to assess and describe the adsorption characteristics of K on the soils of the shallot farming system in Brebes District, Central Java. Soil samples were collected at several locations in the shallot center areas of Brebes Regency, Central Java Province. The observed soil properties included pH H2O, EC, soil texture, organic C, potential-K, exchangeable Ca, Mg, Na, and K, CEC, exchangeable Al and H, and water-soluble K. K adsorption was simulated by the Freundlich equation. The proportion of K from low to high of retention energy in the soil studied had the order, namely water-soluble K<exchangeable K<potential-K. The K adsorption result showed that the soil had a high capacity to adsorb K. It indicated that added K was accumulated in the soil. The high capacity to adsorb K indicated that K accumulated in Brebes with continuous K fertilization. This research recommended that to increase the efficiency of K fertilizer, it is necessary to introduce the technology to mine K in Brebes soils like bacteria capable of dissolving K or biofertilizers.

Abstract

Using fertilizers is one of the efforts to increase crop productivity, but conventional fertilizers tend to be easily leached so it becomes ineffective. Slow-release fertilizer (SRF) is a modified fertilizer that releases nutrients slowly or gradually so that the use of fertilizer becomes more effective. SRF can be synthesized by mixing fertilizers with zeolite as a slow-release agent. Because natural zeolite contains many impurities that cover the pores of the zeolite, it is necessary to carry out an activation process to increase the pore capacity of the zeolite so that the process of absorption of nutrients in the SRF becomes more leverage. This study aimed to synthesize NPKSMg slow-release fertilizer with coconut shell biochar and activated natural zeolite for red onion plants (Allium ascalonium). Coconut shell biochar was used as a source of potassium. The activation process of natural zeolite was carried out by the desilication method using a basic solution of NaOH as an activator. Based on the results of research using activated natural zeolite on SRF, the surface structure of SRF became more porous, with a porosity percentage of 69.31%. In addition, the use of activated natural zeolites increased the absorption of nutrients in fertilizers. The use of biochar in SRF increased the percentage of porosity by 66.32%. The use of coconut shell biochar as a matrix and activated natural zeolite as a slow-release agent in SRF NPK S Mg for red onion plants has succeeded in increasing red onion yields.
