Abstract

Soil moisture and temperature are parameters of soil physical properties that are closely related to climatic variations. Descriptive Research on "Variation of Moisture Regime and Soil Temperature on Land with Low Cloud Cover" has been done, to determine the variation of soil moisture and soil temperature on land with permanently low cloud cover based on the Terra Modis map on the island of Lombok. Low cloud cover data was obtained from Terra Modis satellite data which were delineated by Lombok maps. Daily rainfall data were collected from the Climatology Meteorology and Geophysics Agency (BMKG) Kediri Station. Moisture and soil temperature were measured periodically at 10 day intervals, for two consecutive months (March and April, 2020). The results showed that soil moisture varied temporally. Soil moisture content was higher in areas with low cloud cover in the dryland with soils type of Typic Eutrudept, Inceptisols order, than in areas without cloud permanent cover. Soil temperature in the open zone (without low cloud cover) was higher than in the zone that always experiences closure

Abstract

Agroforestry is a form of conservation principle in maintaining land productivity. The various variations that exist in agroforestry will be able to improve soil physical properties, especially the dispersion ratio and stability of soil aggregates, these physical properties will help in resisting the pressure or force of the falling raindrops. This study aimed to determine the effect of land use by agroforestry systems on the dispersion ratio and stability of soil aggregates on sloping land. The research method used is the descriptive method with sampling done diagonally. There were 3 agroforestry systems (clove-based agroforestry, coffee-based agroforestry, and durian-based agroforestry) which were studied in 3 replications with upstream, middle, and downstream positions. This research was conducted in January-June 2020 in Santoni Village, Kayangan District, North Lombok. Two main parameters were tested, namely the dispersion ratio and the stability of soil aggregates. The results showed that the average value of the ratio of land dispersion indicated by coffee-based agroforestry was 79.85% and the highest was clove-based agroforestry of 91.56%, these values ​​belong to the highly dispersed class. Unlike the case with soil aggregate stability, the highest average soil aggregate stability value was shown in coffee-based agroforestry of 109 and the lowest was clove-based agroforestry of 60. The soil aggregate stability value when interpreted as coffee-based agroforestry was classified as very stable clove-based agroforestry is a relatively stable class. Coffee-based agroforestry is best applied on sloping land so that soil erosion and land productivity can be maintained.

Agroforestri sebagai bentuk kaidah konservasi dalam menjaga produktivitas lahan. Berbagai variasi yang ada pada agroforestri akan dapat memperbaiki sifat fisika tanah terutama nisbah dispersi dan stabilitas agregat tanah, sifat fisika ini akan membantu dalam menahan tekanan atau gaya dari butiran air hujan yang jatuh. Tujuan dalam penelitian ini yaitu untuk mengetahui pengaruh penggunaan lahan sistem agroforestri terhadap nilai nisbah dispersi dan stabilitas agregat tanah di lahan miring. Metode penelitian yang digunakan adalah metode deskriptif dengan pengambilan sampel dilakukan secara diagonal. Ada 3 sistem agroforestri (agroforestri berbasis cengkeh, agroforestri berbasis kopi dan agroforestri berbasis durian) yang dikaji dengan 3 ulangan dengan posisi di hulu, tengah dan hilir. Penelitian ini dilaksanakan pada bulan Januari-Juni 2020 di Desa Santong, Kecamatan Kayangan, Lombok Utara. Ada dua parameter utama yang diuji yaitu nisbah dispersi dan stabilitas agregat tanah. Hasil penelitian menunjukkan bahwa rata-rata nilai nilai nisbah dipersi tanah ditunjukkan oleh agroforestri berbasis kopi sebesar 79,85% dan yang tertinggi berada pada agroforestri berbasis cengkeh sebesar 91,56%, nilai-nilai tersebut tergolong ke dalam kelas sangat terdispersi. Berbeda halnya dengan stabilitas agregat tanah, rata-rata nilai stabilitas agregat tanah yang tertinggi ditunjukkan pada agroforestri berbasis kopi sebesar 109 dan yang terendah ada pada agroforestri berbasis cengkeh sebesar 60. Nilai stabilitas agregat tanah jika diinterpretasikan agroforestri berbasis kopi termasuk ke dalam kelas sangat mantap dan agroforestri berbasis cengkeh termasuk kelas agak mantap. Agroforestri berbasis kopi sangat baik diplikasikan di lahan miring agar erosi tanah dan produktivitas lahan dapat dipertahankan.

Abstract

One of the tourist destinations in Lombok, West Nusa Tenggara is the Special Economic Zone Mandalika (KEK Mandalika), a coastal tourism area with various supporting infrastructures on an international scale covering an area of 1,035.67 hectares. The pace of development brings environmental impacts, especially the morphology of the land in the form of mountains and hills is exposed by the conversion of land functions from proteced forest to agricultural areas without the application of land conservation methods. Bypass BIL-KEK Mandalika as the main connecting road for this tourism area is 17.2 km long flanked by hills with a slope of >30o and almost all hilly areas have been converted into agricultural areas. In this area there is minimal standing vegetation accompanied by unstable physical conditions, making all hilly areas on the BIL-KEK Madalika bypass classified as a Very High Erosion Hazard Level which reaches > 560 tons/ha/year which triggers more potential hazards. big like landslides and floods. Various steps have been taken, such as: 1) Integration of porang (Amorphopallus) and standing vegetation (canopy) applied in hilly areas in the Bypass BIL-KEK Mandalika area; 2) Emphasizing and preventing the conversion of buffer zones; 3) Rehabilitation of the Bypass BIL-KEK Mandalika Hills Area.

Abstract

This study aims to determine the effect of biochar application on Hg mobility in a closed leaching experiment using gold processing tailings contaminated soil. The factorial experiment was set up using a Completely Randomized Design (RBD) which tested three types of biochar (rice husk biochar, coconut shell, and corncob biochar) and three doses of biochar (0.10 tons ha-1 and 15 tons ha-1). The PVC column containing a mixture of polluted soil and dibiochar was washed four times with deionized water for a total of 1090 ml of watering. The results showed that the application of biochar can reduce the mobility of mercury (Hg) in small scale gold processing tailings polluted soils. The dissolved Hg concentration in the leachate decreased with increasing dose of biochar application. Leachate from corn cob biochar (15 tons ha-1) treatment showed the lowest Hg concentration of 0.0012 ppm but was not significantly different from leachate from the soil column that was applied coconut shell and rice husk biochar. The concentration of Hg in the leachate for all biochar treatments ranged from 0.0012 - 0.0062 ppm, significantly different from the leachate concentration of the soil column without biochar, which was 1.62 ppm. This provides an indication that biochar can reduce the leaching rate, so that the concentration of Hg is not much leached into the soil. Therefore, biochar can be used as a soil enhancer in remediation of mercury (Hg) polluted soil so that it can slow down the mobility of mercury (Hg) so that it has a small impact on the environment.

Abstract

This study aims to determine the potential of biochar on the mobility of mercury (Hg) in polluted soil planted with mustard greens (Brasicca juncea) and to determine the growth response of mustard greens (Brasicca juncea) in absorbing mercury (Hg). This study used the experimental method, which is a method that aims to examine the effect of biochar application at various doses on the mobility of mercury using the indicator plant mustard greens (Brasicca juncea L) in mercury (Hg) polluted soil. This experiment was carried out from March to June 2023 in the Greenhouse of the Faculty of Agriculture, University of Mataram. Soil samples were collected in Pelangan Village, Sekotong District, West Lombok Regency at several points near the gold processing unit. The samples were taken at top soil of 30 cm with a distance of 100 cm from the processing site then composited. Soilschemical properties including concentration of Hg before and after experiments were measured. Agronomic variables include fresh and dry weight of roots, total dry weight of and concentration of Hg) in plant tissue were also measured. The results of the study showed that the application of rice biochar reduced mobility of Hg in soils. The concentration of extractable-Hg in biochar-treated soils were lower compared to control. This is likely related to the potential adsorption of a number of IHg and MeHg by the negative surface of the biochar and also the formation of association of Hg bonds with the functional groups of the biochar. However, this needs further confirmation.

Abstract

Cayenne pepper is one of the basic commodities and has high economic value. Chili contains capsaicin which gives spicy taste that suitable in various Indonesian food. The high demand of chilies means that this commodity often experiences high selling prices at certain times, especially during the rainy season. The demand that continues to be needed by the community creates great opportunity for chili farmers to continue providing chili on the market. As a plant that can grow well in tropical areas, including Indonesia, chili plants can grow well outside the rainy season. On the other hand, the vertisol soil type, which expands and contracts, requires strong chili plant roots. The rainy season causes plant roots to rot quickly due to waterlogged conditions and plants are easily attacked by pests and diseases. In anticipating failed chili harvest, farmers need planting strategy and selecting quality chili seeds, they can adapt to various environmental conditions. This research was carried out in Sukadana Village using Randomized Block Design field trial method by planting three varieties of chili to find out which variety is most adaptive to waterlogging conditions. The results of the research show that lokal varieties of chili are the most adaptive and resistant to waterlogging conditions.
