The study was conducted in 2012 and 2013 in Tamanbogo Experimental Farm consists of 3 activities, namely 1). To evaluate the kind and amount of feed consumed by 20 heads of cattle and the amount of manure produced, 2). To evaluate the amount of biogas, sludge and slurry produced by digester, and 3). To study the application of manure, dried sludge manure, and NPK fertilization on the growth and yield of hybrid maize of Pioneer 27 (P27). The research results showed that the total weight of feed consumed in the rainy season and in the dry season has already achieved to the recommendation of 10% of the body weight of cattle. The average production of manure and urine were 11.25 kg head-1 day-1 with the biogas production of 3 m3 day-1 was sufficient for cooking and lighting for 5 members of family daily. The by-product of biogas production was 8 kg day-1 of sludge and 127 L day-1 of slurry. The grain yield of P27 with application of dried sludge accompanied with 50 % of NPK fertilizer recommendation dose gave the highest yield of P27 (4.45 t ha-1) with a profit Rp. 3,466,000 ha-1 and B/C of 1.5

Abstrak. Drainase dan pemupukan pada lahan gambut dapat menstimulasi dekomposisi gambut, sehingga menyebabkan kehilangan karbon terutama dalam bentuk emisi CO2 ke atmosfer. Dua seri percobaan telah dilaksanakan, yang bertujuan untuk melihat pengaruh kotoran hewan sapi (kohe) dan pupuk buatan terhadap fluks CO2 pada lahan gambut yang didrainase. Penelitian dilaksanakan di Desa Lubuk Ogong, Kecamatan Bandar Seikijang, Kabupaten Pelalawan, Propinsi Riau, dari bulan Oktober 2011 sampai dengan Januari 2012. Percobaan pertama yaitu membandingkan tiga perlakuan terdiri atas: 1) kontrol (tanpa perlakuan); 2) aplikasi 10 t ha-1kohe dan 3) kombinasi 10 t ha-1kohe dengan pupuk buatan (urea = 0,1 kg m-2; SP-36 = 0,11 kg m-2; dan KCl = 0,09 kg m-2). Masing-masing perlakuan diulang tujuh kali dengan rancangan acak kelompok. Percobaan kedua merupakan plot berpasangan yang membandingkan antara perlakuan aplikasi pupuk kandang (kotoran sapi) dosis 10 t ha-1 dengan tanpa pupuk pada lahan gambut yang didrainase. Emisi CO2 dari permukaan tanah ditangkap dengan sungkup tertutup dan konsentrasinya diukur dengan Infrared Gas Analyzer (IRGA). Hasil penelitian menunjukkan bahwa aplikasi pupuk kandang nyata meningkatkan fluks CO2, namun kombinasinya dengan pupuk buatan tidak nyata meningkatan fluks CO2 bila dibandingkan dengan perlakuan kontrol. Setelah dua bulan setelah aplikasi pupuk kandang, nilai rata-rata fluks CO2 10% lebih tinggi dibandingkan plot tanpa pemberian pupuk kandang. Keragaman data hasil pengukuran fluks CO2 di lahan gambut sangat tinggi, baik secara temporal, maupun lintas perlakuan. Abstract. Drainage and fertilization on peat soils stimulate the decomposition process of peat material, thus substantially increase carbon losses from the soil, especially in the form of CO2. We conducted two series of experiments to study the effect of manure application on CO2 flux in drained peatlands in Lubuk Ogong Village, Bandar Seikijang Sub-District, Pelalawan District, Riau Province from October 2011 to January 2012. The first trial using randomized complete block design consisted of three treatments including: 1) control (no treatment); 2) Application of 10 t ha-1 cow barnyard manure; and 3) combination of 10 t ha-1 manure and chemical fertilizer (urea = 0.1 kg m-2; SP-36 = 0.11 kg m-2; and KCl = 0.09 kg m-2) with three replications. The other trial carried out in pair plots comparing with and without application of 10 t ha-1 manure. CO2 emitted through peat soil surface was captured using closed chambers and its concentration was measured using an Infrared Gas Analyzer (IRGA). The results showed that application of manure significantly increased the flux of CO2, while combination of manure and chemical fertilizer did not increased CO2 flux compared with control. During the two month period after manure applied, CO2 flux average in manure plot was 10% higher than that without manure. Moreover, we found large temporal and treatment-related variations of CO2 flux in peatlands.

One of the simplest analysis and often used as a preliminary analysis of the quantitative research is descriptive statistical analysis. This analysis aims to describe the results of the calculation of numerical data. Some descriptive statistical analysis techniques that are commonly used include: 1) The presentation of data in tables or histograms, 2) The central tendencyof data, 3) The dispersion of data, and 4) The distribution of data. In the analysis of UAS Ekonomitrika with SPSS 23 and Eviews 8.1, found differences in the operational steps in each of these programs. The output of SPSS 23 displays histogram curve is accompanied with normality, explained the value of the variance, standarderror of the mean, standard error of skewness, and kurtosis , but in Eviews 8.1 not display case. In contrast, in Eviews 8.1 displays the value of the JB, the probability JB, sum.square deviation value while in SPSS 23 is not so. The equation of the output that is displayed on the two programs, namely: 1) Displays the number of observational data is processed, 2) Showing mean, median, mode, sum, minimum, maximum, skewness and kurtosis, and 3) Present Histogram.

Knowledge of integration between mathematics and religion is necessary to increase a Muslim's mastery of scientific treasures. This article describes several mathematical concepts contained in prayer movements and Mushofahah. This research is a qualitative descriptive research type of literature review. Data/information collection methods are carried out by observation and documentation. These two methods are used to collect information about mathematical concepts contained in prayer movements and Mushofahah, obtained from several primary and secondary sources in the form of the al-Qur’an, al-Hadith, books, and scientific journals as well as documentation of prayer movements and Mushofahah (shaking hands). The data analysis technique used is content analysis. The research results showed many daily life activities, including prayer and Mushofahah, concrete examples of the integration of mathematics and Islamic religion. These concepts include: In the prayer movement, there were number concepts, which included the addition and multiplication of integers, algebraic concepts in the form of sets, arithmetic sequences, and geometric concepts in the form of lines and angles. Meanwhile, in Mushofahah, there were factorial concepts, permutation concepts, and opportunities.

Studies have shown that coal fly ash (CFA) can improve soil physical properties (such as bulk density) and increase available water content. However, its pozzolanic properties may also contribute to soil compaction. The overall impact of these contrasting effects on soil behavior remains insufficiently understood. This study investigated the effects of CFA amendment on soil resistance, water retention, and corn root growth in sandy soil. Using a completely randomized design, the research was conducted at the Taman Bogo Agricultural Station in East Lampung for two planting seasons (October 2022 - June 2023). Four CFA rates (0%, 3%, 6%, and 12% w/w) were applied in lysimeter plots with five replications. The results demonstrated that CFA application reduced soil bulk density (BD) at 6% and 12% rates due to CFA’s lower BD than the soil. However, higher CFA doses increased soil penetration resistance (PR), likely due to surface crust formation rather than pozzolanic reactions. Plant available water capacity (PAWC) significantly increased by 6% and 12% CFA, thus improving soil water retention. Improving physical properties in the second season promoted root growth at the 12% CFA rate. The use of CFA in sandy soils leads to improvement in selected physical properties and enhances water retention. Therefore, while CFA enhances water retention, its effects on soil compaction and root growth must be carefully managed to ensure optimal results.
