Abstract

Enzyme activity can be used as a peat decomposition indicator in the oil palm rhizosphere of peatlands. Oil palm plantation management requires fertilization in the rhizosphere to provide nutrients for oil palm growth. The state of total nutrient in the rhizosphere can influence enzyme activity. This research aimed to study enzyme activity in relationship to nutrients in the oil palm rhizosphere of peatlands. Using the explorative method in Riau’s tropical peatlands, an oil palm plantation was chosen as a location for the main sites, and a degraded forest as well as a shrubland were chosen as comparison sites. In the oil palm plantation, peat samples were taken from peats adhering to oil palm roots at the peat depths of 0‒25 and 25‒50 cm and at distances of 0‒1, 1‒2, 2‒3, and 3‒4 m from the trees. In the degraded forest and shrub, t samples were taken from selected plant roots at the depths of 0-25 and 25-50 cm. The triplicate peat samples were then composited for an analysis of enzyme activity and total nutrient content. Results showed that enzyme (urease, phosphatase, β-glucosidase, and laccase) activity in the oil palm rhizosphere decreased as the distance from trees and the depth of rhizosphere increased. The decline in enzyme activity was caused by a low peat pH and an increased water content as well as organic carbon content. Enzyme activity increased with increasing oil palm age and ash content. Total K and Zn contents showed no correlation with enzyme activities. However, total Ca and Mg contents showed positive correlation only with β-glucosidase activity. Total Fe and Cu contents showed significantly negative correlation with enzyme activities (urease, phosphatase, β-glucosidase, and laccase). Enzyme activity in the rhizosphere of the degraded forest and shrubs were mostly lower than in the oil palm rhizosphere.

Abstract

Arable soils located in the vicinity of urban and industrial area are considered vulnerable to heavy metals pollution.  Chemical inactivation, an in situ remediation method that used inexpensive chemicals to reduce pollutant solubility in polluted soil, was examined on a Cd-spiked arable soil. The study was aimed at to investigate the effectiveness of ameliorants and fertilizers normally recommended for crop cultivation, using tomato as the test plant, from the point of view to reduce soil Cd extractability and plant Cd concentration. A 100-day greenhouse experiment in completely randomized de­sign consisting of three rates of rationale dosage of ameliorants and fertilizers (RDAF) [0, 50, 100%] and four levels of soil Cd spike [0, 10, 20, 40 mg Cd kg-1 soil, using 3CdSO4.8H2O] in triplicate was conducted. The 100% rate of RDAF applied was: 4 ton dolomite ha-1, 30 ton cow dung ha-1, 150 kg N ha-1 (½ Urea + ½ Ammonium Sulfate), 150 kg P2O5 ha-1 (SP-36) and 100 kg K2O ha-1 (KCl). Significant reductions in soil extractable Cd (CdNH4OAc-EDTA) [from 13.35 to 8.77 mg kg-1, 34%] and plant shoots-Cd (Cdps) [from 8.66 to 5.46 μg g-1, 37%] were measured at 100% RDAF treatment as compared to the control soil, indicating the occurrence of an in situ soil Cd inactivation and plant element selective-uptake phenomenon. Multiple regression analysis that incorporating all 36 data pairs resulted in the following equations: (1) soil CdNH4OAc-EDTA = – 0.18 pHH2O + 0.21 PBray#1 + 0.51 organic-C – 0.57 exch.-Mg + 0.65 Cdaqua regia (R2 = 0.76), and (2) Cdps = 0.08 Nps – 0.17 Kps – 0.19 Mgps – 0.24 Pps + 0.27 Sps – 0.41 Caps (R2 = 0.54, 3 outliers removed). These results suggest that a proper amelioration and fertilization program may be prospective to be recommended as a low-cost Cd pollution remediation strategy for arable soils

Abstract

Blotong merupakan limbah yang paling dianggap mencemari lingkungan dan menjadi masalah bagi pabrik gula dan masyarakat. Terdapat pula anggapan blotong merupakan limbah yang tidak bernilai bahkan dianggap sebagai limbah B3. Blotong salah satu bahan organik yang ketersediannya melimpah dan belum dimanfaatkan dengan optimal. Blotong mangandung hara yang sangat dibutuhkan oleh tanaman, sehingga sangat bagus untuk meningkatkan komposisi kandungan hara pada pupuk majemuk granul. Tujuan yang ingin dicapai pada penelitian ini yaitu: mengkaji pengaruh penambahan blotong pada proses produksi pupuk majemuk granul terhadap serapan hara tanaman. Penelitian dilakukan dalam dua tahap, yaitu granulasi pembuatan pupuk dan pengujian serapan hara tanaman. Tahap granulasi dilakukan menggunakan metode granulasi basah pada formula pupuk majemuk 15-15-15+5S dengan variasi filler blotong (0%, 60%, 70%, 80%, 90% dan 100%) dan sumber K (KCl dan SOP). Sedangkan uji serapan hara dilakukan untuk mengetahui efektifitas pupuk dengan menggunakan tanaman uji jagung manis. Uji tahap kedua dilakukan dengan melakukan pengukuran tinggi tanaman, jumlah daun dan diameter batang pada 2MST sampai 8 MST serta pengukuran hasil produksi dan serapan hara N, P, K tanaman. Hasil penelitian diperoleh, penambahan filler blotong 60%-90% pada perlakuan menggunakan SOP dapat meningkatkan serapan N sebesar 84,93-384,18 mg, serapan P sebesar 2,65-11,62 mg, dan serapan K sebesar 25,04-82,38 mg. Sedangkan perlakuan menggunaan KCl memberikan pengaruh positif pada penambahan filler blotong 70%, dengan peningkatan serapan hara N, P dan K berturut-turut 45,62 mg, 3,87 mg dan 4,89 mg. Hasil produksi tongkol berkelobot tertinggi diperoleh pada perlakuan K2B1 sebesar 1,23 kg sedangkan analisa serapan hara tanaman N dan P tertinggi dihasilkan pada perlakuan K2B4 sekaligus menghasilkan peningkatan hasil tanaman 4,7% dibanding pupuk standar.

Abstract

Cilembu sweet potato is a unique commodity with high demand market due to its sweet taste. The objectives of this study were to investigate the production performance of Cilembu sweet potatoes in term of production classes and critical limit and to determine discriminating land characteristics classes of yield and total sugar content. This study was conducted in Cilembu sweet potatoes production centers in West Java. Sweet potatoes tuber and soil samples were collected by purposive random sampling during harvest. Cilembu sweet potatoes production classes were defined by decreasing yields criteria in land evaluation. Critical limit production was the lowest yield and total sugar content of raw tuber which harvested in Cilembu village. Discriminating land characteristics were decided by discriminant analysis. Results showed that there was a significant different yield between typical and nontypical areas. Critical limit of yield and total sugar content were 10.5 t ha-1 and 2.32 %, respectively. The discriminating land characteristics of yield classes were soil properties (pH, CEC, P, Ca, Mg, ΔT), and monthly rainfall, whereas for total sugar content classes were effective soil depth, clay, sand and monthly rainfall. These variables are proposed as diagnostic criteria in Cilembu sweet potato land suitability criteria.

Abstract

Respirasi tanah terdiri atas respirasi autotrof dan heterotrof. Pada lahan gambut, respirasi heterotrof setara dengan laju dekomposisi bahan gambut. Penelitian ini bertujuan mengembangkan model potensial redoks (Eh) tanah sebagai penduga respirasi heterotrof dari perkebunan kelapa sawit pada lahan gambut tropika. Respirasi tanah diukur menggunakan metode sungkup tertutup pada plot close-to-tree (berjarak 2 m dari pohon) dan far-from-tree (4.5 m dari pohon), sedangkan untuk respirasi heterotrof pada plot root-cut (4.5m dari pohon) yang disiapkan dengan pemotongan akar hingga kedalaman 80 cm dan diinkubasi selama 8 bulan. Respirasi tanah pada lokasi penelitian 40.81 ton CO2 ha-1.th-1, 50.53% darinya berasal dari respirasi komponen heterotrof (RKH). Respirasi heterotrof berkorelasi positif dengan Eh tanah pada pH 7 di kedalaman -30 dan -90 cm (Eh7~30 and Eh7~90) dan berkorelasi negatif dengan tinggi muka air tanah. Nilai koefisien korelasi linier sederhana yang signifikan, r= 0.84 dan 0.87; n= 12, dengan RKH masing-masing ditunjukkan oleh Eh7~30 and Eh7~90. Oleh sebab itu, kedua faktor tersebut dapat disarankan sebagai penduga RKH dengan persamaan: RKH (ton CO2 ha-1.th-1) = 18.2 + 0.029 Eh7~30 + 0.037 Eh7~90 (Eh dalam mV).

Abstract

Different types of soil and the geographical areas of oil palm plantations generate variations in soil physical properties (e.g. texture and porosity). Differences in geographical location further result in variations in the amount of rainfall that affects the water balance. The response to diverse fluctuations in palm oil production due to variations in soil types and water balance can be assessed through correlation analysis between water balance parameters and oil palm productivity under varying soil types and regions. In this study, the water balance analysis was carried out at three locations of PT Bumitama Gunajaya Agro's oil palm plantations in Central Kalimantan and West Kalimantan provinces, using the Thornthwaite-Mather method. Analysis of the relationship between water balance components and oil palm fresh fruit bunch (FFB) yields is calculated based on monthly data for 8 years (2012 - 2019) using time series analysis and stepwise regression to find the best regression model. The water balance components that most influence the fresh fruit bunches (FFB) yield (tonnes/ha/month) are rainfall 7 months before harvest, rainy days 11 and 28 months before harvest, and water deficit 10 months before harvest. A decrease in FFB yield (tonnes/ha/month) occurs every time there is an increase in water deficit of 10 mm/month on Dystrudept, Paleudults, and Haplohumods soils in Area 3, respectively 11, 2, and 3%. In Area 5 the decline is 12, 4, and 5%. In Area 6 the decline is 5, 18, and 3%.

Abstract

There were three pilars of palm oil plantation in Indonesia, state-owned large estates and private estates which total extensive oil palm plantations area in 2005 were 5.445 thausands hectares with 12.452 thausands million tons production crude palm oil. The composition of the plantation farmers area was 40,02 %, national large plantations was about 13,96 %, and 48,68 % for private estates.There are two types of Management of their field, nucleous estate smallholders (NES) and farmers. Unfortunately farmers better than independent farmers in managing the estates, because there was cooparation between the farmers with the nucleous companies. The PIR system stated that the nucleous plantation companies were useful in developing and crops farmers market assigning, While the farmers must manage his estates well and market the results through the company's nucleous. Sustainability analysis conducted by the method of Multi Dimensional Scaling (MDS) approach with Rap-Insus palm oil techniques (Rapid Appraisal-Index Sustainability of palm oil Management). Analysis of key factors of sustainability management performed a prospective analysis of the sensitivity factors (leverage factor) of the MDS and the factors from the analysis of stakeholders' needs. The results showed that the status of sustainability of palm oil management in PT.Perkebunan Nusantara VII Muara Enim, South Sumatera)was quite sustainable with a multidimensional index of 67,67.
