Abstract

There are many agricultural land using irrigation water from polluted industrial waste of heavy metals. Improvement of agricultural land quality using fitoremediation is needed to overcome heavy metal pollution. The reasearch aims to make remedies for paddy field polluted by cadmium (Cd) and copper (Cu) using plants that have the ability to absorb heavy metals in order to increase the quality of the land. This research was conducted at the screen house of Indonesian Agricultural Enviroment Research Institute, using a Randomize Block Design (RBD). Hyperaccumulator treatment plant, consisting of T1: mendong (Fimbristylis globulosa), T2: grass types tekian (Cyperus platystylis), T3: jugul (Borreria laevis), T4: spinach (Amaranthus spp.), T5: mustard (Brassica juncea), T6: bundung ganal (Scleria poaeformis), T7: purun tikus (Eleocharis dulcis), T8: karapiting (Polygonum hydropiper), T9: hiring-hiring (Rhynchosphora corynbosa), and T10: purun kudung (Leperonia mucrunata). The results showed that the content of heavy metals Cd and Cu in Vertisols (Sambung Macan and Sragen) are 1.18 and 31.38 ppmrespectively. All hyperaccumulator plants on Vertisols polluted by cadmium (Cd) can reduce the levels of soil cadmium after two months planted (Duncan test level 5%). The content of copper (Cu) in soil indicated an increase and significantly different (Duncan test level 5%). Purun kudung is significantly different compared with mustard in term of Cu adsorption from soil. The Cu content on two months old spinach is higher than othertreatments, but the highest Cu content occurs on stems and leaves of jugul plant. The content of cadmium (Cd) on roots of jugul plant is the highest and significantly different, while thecontent of Cd on hiring-hiring plant is also the highest content but not significantly different.

Abstract

Abstract. Newly developed wetland rice fields require more water because plough pan layer are not developed. Plough pan is established several years after the field development and its formation depends on the intensity of rice cultivation and the soil properties. Plot scale study was conducted on newly developed wetland rice field originated from upland in Pati village, North Kalimantan Province, Indonesia in 2013. The aim of this experiment was to study the water productivity of the newly developed wet land rice fields. Different water ponding treatments including water ponding layer of 5 cm as control (T0), ponding layer of 3 cm (T1) intermittent with two weeks wetting and one week drying (T2), and saturated condition with water layer of 0.5 cm (T3) were tested. Rice growth, rice grains yield and water productivity were evaluated. Water productivity was computed according to the ratio between rice grains yield and water input. Water input was predicted based on the difference between incoming and outgoing water. In this study water balance was not taken into account in calculating the water input. The results indicated that under saturated condition (T3), plant height and tiller number were significantly lower than the 5 cm ponding and also significantly lower than other treatments. Water productivity between 0.78 and 0.40 gram liter-1 were recorded under ponding water depth of 0.5 cm and intermittent ponding of 5 cm in the wet period. Abstrak. Sawah bukaan baru membutuhkan banyak air karena lapisan tapak bajak belum terbentuk. Lapisan tapak bajak akan berkembang setelah beberapa tahun tergantung pada intensitas penanaman padi. Percobaan pada skala plot dilaksanakan pada sawah bukaan baru yang berasal dari lahan kering di Dusun Pati, Kabupaten Bulungan, Kalimantan Utara pada tahun 2013. Penelitian bertujuan untuk mempelajari produktivitas air pada sawah bukaan baru. Beberapa perlakuan tinggi genangan air diuji dalam penelitian ini meliputi tinggi genangan air 5 cm sebagai kontrol (T0), tinggi genangan air 3 cm (T1), Intermitten dengan dua minggu periode basah dan satu minggu periode kering (T2), dan macak-macak atau jenuh air dengan tinggi genangan air 0,5 cm (T3). Data yang diambil meliputi pertumbuhan tanaman padi, hasil gabah dan produktivitas air. Produktivitas air dihitung dengan perbandingan antara hasil gabah dengan air yang dibutuhkan, sedangkan air yang dibutuhkan dihitung berdasarkan selisih antara air yang masuk ke sawah dengan air yang keluar dari sawah. Hasil percobaan menunjukkan bahwa perlakuan macak-macak atau jenuh air dengan tinggi genangan 0,5 cm menghasilkan tinggi tanaman dan jumlah anakan padi yang secara nyata lebih rendah dibandingkan dengan perlakuan kontrol dengan tinggi genangan air 5 cm dan perlakuan lainnya, tetapi menghasilkan produktivitas air yang tertinggi yaitu 0,78 gram liter-1. Produktivitas air yang memberi harapan yang menjanjikan pada sawah bukaan baru adalah antara 0,78 – 0,40 gram liter-1 dengan perlakuan macak-macak dengan tinggi genangan air 0,5 cm dan intermitten dengan tinggi genangan air 5 cm pada periode basah.

Abstract

Industrial wastes may pollute agricultural land, which is leading to the contamination of agricultural yield by heavy metals. The pollution of Mercury (Hg) and Cadmium (Cd) on paddy field on rice growth is hard to observe, but the contents of Mercury (Hg) and Cadmium (Cd) on hulled-rice exceed the safety level. Therefore Research should be conducted to study the critical limit of Hg and Cd in soils from paddy field. Soil polluted by Hg and Cd should be remediated physically, chemically, or biologically before it is used for agricultural land. The objectives of the study were to know the effect of heavy metal on harvest yields; to find out the relationship between the contents of Mercury and Cadmium in the soil and in rice, and to determine the critical level of Hg and Cd in the soil. The study was preceded at the laboratory for determining maximum adsorption of Mercury and Cadmium by soil, and then at green house using pots containing Typic Dystrudepts and Typic Hapluderts as muchas 7.5 kg of dry soil. Each pot was given treatments of Mercury and Cadmium with the rate of ; 0, 0.1, 0.2, 0.4, and 0.6 of maximum adsorption by soil, afterward stired and incubated for seven days. Each pot was planted with rice IR-64 as indicator plant. This experiment used Randomised Completely Design with three replicates. The research results showed that the increase of Hg content in soil does not decrease unhulled-rice yield, on the contrary the increase of Cd in soil decreases hulled-rice. Coefficient of correlation (r) between Mercury content in soil and in hulled-rice is 0.79 and 0.94 respectively, while for Cadmium is 0.98 and 0.97. The critical limit of Mercury content in Typic Hapluderts and Typic Dystrudepts is 7.1 and 13.6 mg kg-1 respectively, while the critical limit of Cadmium in Typic Hapluderts and Typic Dystrudepts is 3.9 and 6.9 mg kg-1.

Abstract

Ultisols from andesitic volcanic material in lower slope of Mt. Ungaran are different from other Ultisols, especially in their exchangeable aluminum content, P nutrient status (retention and available P), and mineralogy of sand fraction which is dominated by opaque mineral. Interpretation results of physical, chemical, and mineralogical data from six representative soil profiles inform that Ultisols in the reconnaissance map of Central Java consist of three groups: (1) Oxisols (pedons P1 and P2) due to their clay CEC of < 16 cmolc kg-1, even though the soil structure is angular blocky, (2) Ultisols (pedons P3, P4, and P5), and (3) transition from Inceptisols to Ultisols (pedon P6) due to the unclear argillic horizon and broad form of x-ray diffraction pattern. Domination of opaque mineral indicates that nutrient retention is low for a long time. Exchangeable aluminum in the first and second group are very low and not detectable, except in the third group. Available P in the first group is moderate, while in the second group is low (P3 and P5) and high in P4. This condition indicates that theavailable P is influenced not only by aluminum but also by other factors needed to be further studied. Low available P in the third group is due to fixation of P by aluminum. Based on the soil fertility characteristics, mineralogy, and pedogenesis of every group, development of tree crops (such as rubber) in the second group should consider to overcome clay accumulation (or argilic horizon) which may constrain root development. The first group needs addition of organic matter to increase nutrient retention and improve soil stucture.

Abstract

In Tawangmangu, citrus (Citrus nobilis L.) has a specific taste which may be affected by biophysical characteristics such as soil and climate. Yet, the nature of this citrus in relation with biophysical characteristics is rarely studied. The present study was aimed to (1) identify variables of soil and climate that affect the quality of citrus, and (2) characterize the quality of citrus spatially and temporally. The study was conducted covering deskstudy, field survey and laboratory analysis. Climate and soil parameters were ascertained by identifying citrus and its production, characterizing the farmer practices, observing selected climate and soil parameters, and formulating the selected climate and soil parameters in every stage of citrus growth. The quality of citrus product was ascertained throughlaboratory and organoleptic analysis. The results showed that citrus has better internal quality under the topography of more than 1,000 m above sea level (asl) and the average rainfall of 3,166 mm year-1, on Acrudoxin Hapludands soils compared with that growing in area of lower than 1,000 m asl and the average rainfall of 2,715 mm year-1 on Typic Dystrudepts soils. Citrus of Tawangmangu with good quality of yield needs low temperatureabout 190C and radiation about 320 kal cm-2 in flowering season while high and stable temperature of 22-230C and radiation about 400 kal cm-2 are needed during maturing period until fruiting period. Total Dissolved Solid and acid values significantly affected by most of macro nutrient i.e. N, P, K and micro nutrient i.e. Fe, B, and Cu, and also sand mineral i.e. opaque, volcanic glass and labradorit under the topography of more than 1,000 m asl. Meanwhile in area of lower than 1,000 m asl, total solublesolidity significantly affected by CEC, Al, organic matter, micro nutrient and also Opaque, Volcanic Glass and Labradorit. Acid value significantly affected by macro nutrient. Sweets content significantly affected by Hornblende, Augit, and Hiperstin. Therefore, citrus of Tawangmangu can be more adaptable if planted in Typic Dystrudepts on area of more than 1,000 m asl.

Abstract

Abstrak: Salah satu faktor yang mempengaruhi variabilitas iklim Indonesia adalah El-Nino southern oscillations (ENSO). ENSO memberikan dampak yang signifikan pada sektor pertanian. Selama ini kajian pengaruh ENSO terhadap produksi pertanian lebih banyak terfokus pada tanaman pangan sementara pada tanaman hortikultura masih terbatas. Penelitian ini mengidentifikasi pengaruh ENSO terhadap produksi dan dinamika puncak panen durian (Durio zibethinus Murr). Data yang digunakan dalam penelitin adalah data triwulan produksi durian periode 1990-2015 seluruh wilayah Indonesia sedangkan indeks yang digunakan untuk mengetahui fase ENSO adalah Oceanic Nino Index (ONI). Pendekatan yang digunakan untuk melihat pengaruh ENSO terhadap dinamika produksi dan puncak panen dalam penelitian ini adalah membandingkan produksi dan puncak panen pada ketiga fase ENSO. Tahun ENSO yang dipilih adalah tahun-tahun El-Niño/ La-Niña dengan intensitas moderat, kuat dan sangat kuat. Hasil penelitian menunjukkan bahwa ENSO, El-Niño dan La-Niña menyebabkan penurunan produksi durian di hampir seluruh wilayah Indonesia. Penurunan produksi pada tahun La-Niña lebih signifikan dibandingkan El-Niño. ENSO juga menyebabkan pergeseran puncak panen durian. Pergeseran puncak panen baik maju atau mundur bervariasi antar wilayah sehingga belum terlihat jelas pola pergeserannya. Kalender budidaya durian yang selama ini dilakukan oleh petani, pada tahun El-Niño dan La-Niña perlu disesuiakan baik waktu maupun kegiatan budidayanya. Hal ini diperlukan untuk menstabilkan produksi pada tahun El-Niño dan La-Niña.Abstract. One of the factors influencing Indonesia's climate variability is El-Nino southern oscillations (ENSO). ENSO has a significant impact on agricultural production. ENSO studies in the past focused more on food crops than on horticultural crops. This study aimed to identify the influence of ENSO on durian (Durio zibethinus Murr) production and peak of harvest season. This study used quarterly production data from 1990-2015 for all provinces in Indonesia and The Oceanic Nino Index (ONI) data were used to determine ENSO Phase. The peak harvest season and production at three different ENSO phases were compared. The analysis showed that ENSO both El-Niño and La-Niña decreased durian production whereas the production decrease in La-Niña years was more significant than in El-Niño years. ENSO also shifted durian peak harvest season. The alteration of harvest season peak varied across provinces and its pattern is still unclear. The existing durian cultivation calendar needs to be adjusted to stabilize durian production during ENSO events.
