Abstract

Low P availability is the main constraint for crops on acidic soil such as an Ultisols due to high soil P sorption. The objective of current research was to determine the effect of coal fly ash-chicken manure mixture application on P use efficiency by corn (Zea mays L.) in Ultisols. The research were arranged according to Factorial Completely Randomized Design with three replicates. The treatments tested were the rates of FA-CM mixture (w/w of 1:1) that consisted of 0, 15, 30, 45 and 60 tons ha-1, and P fertilizer rates that consisted of 0, 0.5, 1.0, 1.5 and 2.0 times of P requirement to achieve of 0.2 μg P mL-1 in soil solution (equivalence to 0, 87, 174, 261 and 348 kg P2O5 ha-1). Results of current research showed that P use efficiency by corn on Ultisols had been increased through the addition of FA-CM in combination with P fertilization at the rate of 87 kg P2O5 ha-1. The optimum rate of FA-CM in combination with P fertilizer at the rate of 87 kg P2O5 ha-1 is 28.60 tons ha-1, with P uptake efficiency of 42.41 % and agronomic P efficiency of 82.53 mg shoot dry weight/mg P from fertilizer.

Abstract

ABSTRAK. Peranan gambut terhadap lahan degradasi menjadi sangat penting dan bernilai dalam hal cadangan karbon karena berdampak terhadap hilangnya vegetasi akibat penggundulan dan kebakaran hutan. Penelitian ini dilaksanakan pada lahan gambut pada agrosistem kelapa sawit di Kabupaten Ogan Komering Ilir, Sumatera Selatan. Tujuan penelitian ini untuk menduga cadangan karbon gambut. Hasil penelitian menunjukkan bahwa kedalaman gambut berkisar antara 200 – 850 cm, bulk density antara 0,211 – 0,347 g cm-3 dan kandungan organik C sekitar 56,30 - 58,31%. Prediksi cadangan karbon adalah sebesar 1,675.361 - 9.055,922 ton C ha-1. The Prediction of Peatland Carbon Stocks in Oil Palm AgroecosystemsABSTRACT. The role of peat on degraded land becomes extremely important and valuable, for being the last carbon stocks because of the loss of vegetation due to deforestation and forest fires.

Abstract

ABSTRAK. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian campuran abu terbang-kotoran ayam (ATB-KA) terhadap perubahan titik muatan nol (TMN) tanah dan dampaknya terhadap jerapan dan ketersediaan P pada Ultisol. Dua perlakuan yang diuji adalah ATB-KA (w/w 1:1) pada dosis 0, 15, 30, 45 dan 60 ton ha-1, dan pemupukan P pada dosis 0, 87, 174, 261 dan 348 kg P2O5 ha-1.  Perlakuan ini ditata dalam Rancangan Acak Lengkap yang diulang sebanyak tiga kali. Hasil penelitian menunjukkan bahwa aplikasi CATK untuk setiap dosis pemupukan P berkorelasi secara nyata dengan status tanah TMN, pH, muatan negatif, jerapan dan ketersediaan P. TMN berkorelasi positif dengan pH dan muatan negatif. Muatan negatif secara nyata berkorelasi negatif dengan jerapan P, dan berkorelasi positif dengan P tersedia. Modification of PZS of Soil With Variable Charge by Application of Coal Fly Ash-Chicken Manure MixtureABSTRACT. The objective of current research was to study the effect of coal fly ash-chicken manure mixture (FA-CM) on the changes on the soil PZC status and its impact on P sorption and availability in Ultisols. Two treatments - FA-CM mixture (w/w of 1:1) at the rate of 0, 15, 30, 45 and 60 ton ha-1, and P fertilization at the rate of 0, 87, 174, 261 and 348 kg P2O5 ha-1 were tested.  These treatments were arranged according to Factorial Completely Random Design with three replicates. The results showed that the application of FA-CM for each dosages of P fertilizer correlated significantly with the status of soils PZC, pH, negative charge, P sorption and P-available. PZC has possitive correlation with pH and negative charge. Negative charge has a significantly negative correlation with P sorption, and posssitively correlation with P-available.

Abstract

ABSTRACT Changes in Point of Zero Charge and Negative Charge of Coal Fly Ash due to Chicken Manures Addition Fly ash, coal combustion residue of thermal power plants, has been regarded as a problematic solid waste all over the world. Due to the environmental problems created by large-scale fly ash generation, efforts are being made to recycle these materials, such as to improve soil fertility as an ameliorant. In the present study, the possibility to improving the status of point of zero charge (PZC) and negative charge in fly ash (FA) and chicken manure (CM) mixtures was investigated. Fly ash was mixed with chicken manure composition of 0, 25, 75, and 100 % FA (w/w basis) and incubated for 15, 30, 45, and 60 days. Treatments arranged in factorial completely randomized design with 3 replicates. The results showed that the compositions of FA-CM and incubation period significantly affect the status of TMN, negative charge, P sorption and available-P. The mix of 50% FA with 45 days incubation tend to have a lower PZC and P sorption and higher negative charge and P-available. This composition could be use as an amelioran to improve the soils chemical properties in terms to decrease PZC and increase negatif charge, and it is necessary for further research.   Keywords: chicken manure, coal fly ash, point of zero charge, negative charge

Abstract

Relationship between the Organic Matter Content with Post Harvest Period of Forest Industrial Plant Acacia mangium Willd (Sabaruddin, S.N.A. Fitri, and L. Lestari): Timber harvesting may have significant effects on soil organic matter content through mechanical disturbance, inputs of logging slash, alterations in litter production, and leaching of dissolved organic matter, as well as the alteration of temperature and moisture regimes.  To investigate the effect of post-harvest period of tree harvesting on the dynamics of soil organic matter content, surface soils (0 to 10 cm and 10 to 20 cm) were collected from intact Acacia mangium Willd. plantation (control) and from A. mangium Willd. harvested in 2001, 2002, 2004, and 2006 in four replicates.  Each replicate consisted of composited 4 sub-samples.  Timber harvesting reduced litter accumulation on soil surface.  However, the amount of litter accumulated on soil surface increased as post-harvest period increased.  Timber harvesting significantly (p<0.001) affected soil organic matter content both in 0 to 10 cm and 10 to 20 cm.  The increases in soil organic matter content were significantly correlated (r=0.85; p<0.001 in 0 to10 cm and r=0.62; p<0.01 in 10 to 20 cm) with post harvest period.

Abstract: This study aims to determine the improvement of teacher discipline by providing teachers with a reward and punishment system. The subjects of this study were kindergarten teachers in Langkat district, totaling 20 teachers. The results of the research in the first cycle were 75% of teachers were able to apply the discipline of their arrival in every learning activity. The results of the research in the second cycle increased to 90% of teachers who were able to discipline the arrival time in each activity. In the first cycle there are 60% of teachers who complete the administration of learning preparation in their class, while in the second cycle it increases to 80%. Then in the first cycle there were 50% of the teachers did not reach the minimum curriculum target and in the second cycle it decreased to 20% did not reach the curriculum target. From this it can be concluded that teacher awareness in time discipline can improve student learning outcomes, as seen in the results of the research cycle I to cycle II, teacher performance and student learning outcomes have increased significantly. Keywords: discipline; punishment; reward  Abstrak: Penelitian ini bertujuan untuk mengetahui peningkatan disiplin guru dengan memberikan guru sistem reward dan punisment.

Abstract

This study aims to examine the effect of the variable of tax expense, tunneling incentive and leverage on transfer pricing with profitability as a moderating variable. This study is quantitative using secondary data obtained from manufacturing companies with food and beverage sector listed on the Indonesia Stocks Exchange (IDX) in 2015-2020. The sampling process used a purposive sampling technique using several criteria that have been determined by the researcher. The data analysis technique used is panel data analysis using the statistical application of E-Views 12 as a data tool. The results of this study indicate that tax expense, tunneling incentive and leverage on transfer pricing together affect transfer pricing. Partially, tax expense and leverage have a positive insignificants effect on transfer pricing. Tunneling incentive has a positive significants effect on transfer pricing. And then, profitability has a positive significant with tax expense on transfer pricing
