Abstract

Pb and Cd are two types of heavy metal that has been widely contaminates agricultural land. Pollution on agricultural land led to a decrease in productivity, disruption of the ecological balance and impaired human health. The research aims to identify and detect the content of heavy metals Cd and Pb in the soil and measure the effectiveness of the arbuscular mycorrhizal veskular withstand heavy metals in lettuce plants. Soil samples were collected in the Village Sudiang Makassar City using stratified sampling and purposive sampling methods. Sampling points are distinguished based on the distance from the highway, which is 15 meters and 30 meters. Analysis of heavy metal content in soil carried Soil Laboratory BPTP Maros. The study based on a randomized block design in a factorial 2 factors. The first factor was soil sampling and the second factor was the provision of mycorrhizae. Based on the survey results revealed that the content of Pb and Cd in soil belt of northern South Sulawesi has passed the threshold. Due to the reduced content of Pb and Cd after treatment arbuscular mycorrhizal fungi but the decline is not significant compared with no treatment mycorrhizae. The content of Cd and Pb in plants of lettuce grown in the various media and the addition of CAM treatments above the threshold concentration safe for consumption.

Abstract

The large population growth of Indonesia encourages the transition of the function of agricultural land into non-agricultural land. The demand for land from time to time always increased, while the available land limited in number. This caused the conversion of agricultural land into non-agricultural land. This phenomenon certainly could bring serious problems. This study aimed to determine the land productivity index for rice and green beans cultivation and to find out the factors that influence production. The productivity indexes analyzed based on the Storie Approach. Soil sampling was carried out by an open grid method divided based on five land map units which spread across three different villages in Kampili irrigation area. The results of the study indicate that the highest productivity index is shown in SPT 5 where the productivity index is 47 and the lowest productivity index is shown in SPT 2 where the productivity index is 21,6. The land productivity index in the downstream of the Kampili irrigation area, which is located in the district of West Bajeng is poor to sufficient level. The low value of land productivity was strongly influenced due to poor soil quality, especially soil chemical properties. The results of the laboratory analysis show that nutrients in those areas are low.

Abstract

Sub watershed Pasui is an upstream area of Saddang watershed with mountain topography dominated by agricultural cultivation activities of coffee, cocoa, cloves and onions without conservation methods. Agricultural cultivation activities that do not apply conservation methods on steep slopes are expected to increase the rate of erosion in this region. This study is aim to determine the magnitude of potential erosion and erosion hazard index in Sub watershed Pasui upstream Saddang watershed. The method of study is conducted survey and soil sampling in Sub watershed Pasui, Baraka subdistrict and Buntu Batu, Enrekang regency. The study took place from February to August 2021. Erosion restoration uses the USLE method, while the restoration of erosion hazard index refers to The Minister of Forestry Regulation No. 60 of 2014. Paddy field cover, mixed dry land agriculture and forest are classified as low erosion hazard index class with potential erosion value <15 ton/ha/year. Meanwhile, dry land and savanna agriculture belong to a very high erosion hazard index class with a potential erosion value. The weighted average potential erosion value is 189,46 tons/ha/year, while the weighted average erosion hazard index in the Sub watershed Pasui upstream Saddang watershed is 8,83 and belongs to the highest erosion hazard class.

Abstract

The small value of erosion on a land is sometimes ignored even though it can sometimes have an effect on a land. Industrial plantation forests (HTI) are present as a government effort to combine timber production and forest rehabilitation. However, the problems faced are low land productivity, decreased soil fertility due to erosion processes in the soil layer. The research hypothesis is that the use of a layered canopy, good soil infiltration will reduce the rate of erosion and surface flow. This research aims to study the amount of erosion in industrial plantation forests in Tompobulu District, Maros Regency. This research was conducted in January-February 2022 in Bahagia Hamlet, Bontomanurung Village, Tompobulu District which was carried out using the erosion plot method. Erosion plots were made in two stands in monoculture and agroforestry industrial plantation forest areas. The measurement results of the amount of flow rate in monoculture HTI is greater than agroforestry HTI which each has a surface flow, namely 113.86 m3/ha and 55.43 m3/ha. While the erosion rate in monoculture HTI is greater than agroforestry HTI, each of which has an erosion rate, namely in monoculture HTI of 0.19 tons/ha and agroforestry HTI of 0.06 tons/ha. The estimated value of annual erosion and tolerable soil loss (TSL) in each stand, namely monoculture HTI is 2.57 tons/ha/year and 4.69 tons/ha /year, while in agroforestry HTI respectively 1.45 tons/ha/year and 9.69 tons/ha/year. Each of the two stands produced estimates of annual erosion that were smaller than the tolerable soil loss (TSL). Good interception (use of layered canopy, vegetation with large leaf surface area) and good infiltration can reduce erosion and surface runoff.

Abstract

Sistem agroforestri di Dusun Lemo Baru Kabupaten Polewali Mandar memerlukan perhatian khusus mengenai persaingan antar tanaman terhadap serapan hara dan pertumbuhan akar. Penelitian ini bertujuan untuk mempelajari respon akar dan serapan hara kakao dan langsat terhadap dosis nitrogen yang berbeda. Pada kebun agroforestri dilakukan pemupukan nitrogen  dengan empat dosis yaitu perlakuan kontrol; pemupukan Urea dosis 354 g pohon-1; Phonska Plus 500 g pohon-1; dan Phonska Plus 500 g pohon-1 + Urea 190 g pohon-1 diletakkan di ingrowth hole diantara pohon kakao dan langsat. Setelah setahun pemupukan dilakukan pengambilan sampel tanah, akar dan daun. Sampel tanah dan daun dianalisis serapan hara, analisis keragaman dan Independent Sampel T-Tes(2-tailed) dengan taraf kepercayaan 5%. Sampel akar dilakukan perhitungan panjang akar menggunakan software ImageJ, kerapatan panjang akar dan panjang akar spesifik. Hasil penelitian menunjukkan nilai SRL langsat tertinggi pada perlakuan kontrol dan nilai RLD tertinggi pada Phonska Plus 500 g pohon-1. Aplikasi pupuk berpengaruh nyata terhadap SRL kakao dan tidak memberikan pengaruh terhadap RLD. Perlakuan kontrol berbeda nyata dengan pemupukan Urea dengan dosis 354 g pohon-1, Phonska Plus 500 g pohon-1 dan Phonska Plus 500 g pohon-1 + Urea 190 g pohon-1.  Pemupukan Urea 354 g pohon-1 berbeda nyata dengan Phonska Plus 500 g pohon-1 +  Urea 190 g pohon-1.  Nilai tertinggi RLD terdapat pada perlakuan Urea 354 g pohon-1. Serapan hara jaringan langsat dan kakao tertinggi pada pemupukan Phonska Plus 500 g pohon-1 + Urea 190 g pohon-1. Akar langsat mampu menyerap hara lebih banyak dibandingkan dengan akar kakao.
