Abstract

Estimation of soil erosion 3D (E3D) provides basic information that can help manage agricultural areas sustainably, which has not been sufficiently conducted in Indonesia. Sumani watershed is main rice production area in West Sumatra which has experienced environmental problem such as soil erosion and production problem in recent years. 3D Agro-ecological land use planning based on soil erosion 3D hazard and economic feasibility analyses consist of production cost and prize data for each crop. Using a kriging method in Surfer tool program, have been developed data base from topographic map, Landsat TM image, climatic data and soil psychochemical properties. Using these data, the Universal Soil Loss Equation was used for spatial map of soil erosion 3D and proposed a 3D agro-ecological land use planning for sustainable land management in Sumani watershed. A 3D Agro-ecological land use planning was planned under which the land use type would not cause more than tolerable soil erosion (TER) and would be economically feasible. The study revealed that the annual average soil erosion from Sumani watershed was approximately 76.70 Mg ha-1yr-1 in 2011 where more than 100 Mg ha-1yr-1 was found on the cultivated sloping lands at agricultural field, which constitutes large portion of soil erosion in the watershed. Modification of land use with high CP values to one with lower CP values such as erosion control practices by reforestation, combination of mixed garden+beef+chicken (MBC), terrace (TBC) or contour cropping+beef+chicken (CBC) and sawah+buffalo+chicken (SBC) could reduce soil erosion rate by 83.2%, from 76.70 to 12.9 Mg ha-1 yr-1, with an increase in total profit from agricultural production of about 9.2% in whole Sumani watershed.Key words: CP-values, Erosion 3D, land use, Surfer Tool, USLE [How to Cite: Aflizar, AC Idowu, R Afrizal, Jamaluddin, E Syafri, Muzakir, Husnain and T Masunaga. 2013. 3D Agro-ecological Land Use Planning Using Surfer Tool for Sustainable Land Management in Sumani Watershed, West Sumatra Indonesia.

Abstract

Recycling is important for achieving environmentally sustainable products and waste reduction. The trend has led to the addition of reinforcement to recycling process to ensure the effective usage of wasted papers. Therefore, this study was conducted to determine the effect of using cellulose nanofiber (CNF) synthesized from kapok fibers as reinforcement in recycled papers. CNF was applied at different concentrations of 2, 4, 6, 8, and 10% of recycled paper production and the analysis was conducted by testing tensile index, density, and brightness. Moreover, X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and UV-Vis analysis were used to determine the characteristics of the paper. The results showed that CNF addition influenced tensile index, brightness, and density of recycled papers. This was observed from an increase in tensile strength by up to 76.32% and density at approximately 0.58 g/cm3 for 10% CNF addition. Meanwhile, the brightness level was reduced due to the compact nature of paper produced. The trend led to the conclusion that the addition of CNF could impact the characteristics of recycled papers.

Abstract

Sektor perikanan budidaya memainkan peran penting dalam ketahanan pangan dan ekonomi nasional Indonesia. Peningkatan produksi ikan menuntut ketersediaan pakan yang efisien, namun biaya pakan komersial yang tinggi menjadi kendala besar, terutama bagi pembudidaya kecil dan menengah. Penelitian ini bertujuan untuk merancang mesin pelet pakan ikan yang harganya terjangkau, bertenaga bensin, dengan kapasitas produksi 20-50 kg/jam, untuk mendukung produksi pakan mandiri. Metode yang digunakan meliputi perancangan dan perakitan mesin dengan komponen utama berupa screw extruder, roda penggerak, dan cetakan (die). Prototipe mesin memiliki dimensi 60 x 40 x 70 cm, menggunakan motor penggerak 4 tak (3600 rpm, 196 cc, bensin), tipe pencetakan screw extruder dengan diameter die 3 mm, tabung penggiling berukuran panjang 23 cm dan diameter 7 cm. Prototipe mesin diuji dengan bahan baku seberat 10 kg sebanyak lima kali. Hasil menunjukkan mesin dapat menghasilkan daya maksimum 3,46 kW, dengan putaran 720 rpm (maksimum) dan 200 rpm (minimum). Rata-rata kapasitas produksi mencapai 49,49 kg/jam, lebih tinggi dibandingkan mesin motor listrik 1 Hp pada penelitian sebelumnya yang menghasilkan 39,83 kg/jam. Selain itu, analisis scatterplot menunjukkan bahwa semakin banyak pelet yang dihasilkan, semakin lama waktu yang diperlukan, menandakan hubungan linier antara jumlah dan waktu produksi. Beberapa perbaikan diperlukan, seperti penambahan pengunci roda untuk kestabilan. Penelitian lanjutan perlu dilakukan untuk mengoptimalkan konsumsi bahan bakar dan mengevaluasi interval pemeliharaan. Hasil penelitian ini diharapkan dapat memberikan alternatif solusi mesin pelet yang efisien bagi pembudidaya skala kecil dan menengah.

Abstract

Increased environmental and sustainability awareness has fueled efforts to develop bio-based composite materials for a wide range of end-use applications, as well as new alternatives to non-renewable synthetic fibers such as glass and carbon-reinforced composites. Considering development and research, Paederia foetida fiber stem (PFs) reinforced composites have recently generated a lot of interest. Hybrids of PFs with carbon powder (CP) have been explored in order to achieve the best properties for composites. This study focused on investigating the microstructural, mechanical, thermal, and density characteristics of hybrid reinforced epoxy composites made of CP/PFs. Several compositions of PFs and CP (30:0, 20:10, 15:15, 10:20, and 0:30 vol.), were prepared to manufacture composite using a hot press method. The effect of the volume fraction of carbon/PFs on the mechanical, thermal, and fracture structure properties of hybrid composites was examined. The findings showed that sample CDS20 which was made up of 20% PFs and 10% CP had the highest tensile strength (42.3 ± 2.7 MPa) and elastic modulus (2310.8 ± 91 MPa). It also had quite high thermal resistance properties with a residual charcoal content of about 23.8%. SEM analysis showed agglomeration of CP and the number of voids decreased as the volume fraction of PFs increased, and the interfaces between CP-PFs-epoxy appeared denser. For infrastructure applications, this composite may serve as an alternative to epoxy composites reinforced with sisal fiber.

Abstract

This study aims to describe the responsibilities of parents towards children's education at an early age by using a hadith perspective. Parents who are in charge of education have a very dominant role in the process of children's education. Parents and children have an emotional relationship and intensive educative inter action, this can be a positive educational atmosphere. This article is a theoretical study by using data sources from library searches in the form of books and journal articles related to the formulation of the problem. The approach used is an educative approach, which examines the responsibility of parents to children's education at an early age in the perspective of hadith by using qualitative data analysis methods. The research findings are parents as the party who is in the first order responsible for their children's education. The responsibility of parents regarding education concerns the good of the child in this world and the hereafter. The responsibility for children's education has been prepared long before the child is born. In this research there are nine forms of parental responsibility for the education of children at an early age.

Abstract

Human resources in the agricultural sector are faced with the problem of an aging workforce not accompanied by workforce regeneration. This problem is caused by the low interest of the younger generation to participate in the agricultural sector where various factors influence this interest. This study aims to provide an overview of the factors that influence the interest of the younger generation in the agricultural sector. This study was conducted using a descriptive approach with secondary data obtained from research articles related to the interest of the younger generation in the agricultural sector, as well as other supporting data. The data analysis used in this study is interactive analysis and bibliometric analysis. The results of the study show that the interest of the younger generation (<25 years) in the agricultural sector has been very low for the past few years (<10%), with the largest level of education of the workforce in the agricultural sector dominated by low education (>60%). The results of the bibliometric analysis of 34 articles related to the interest of the younger generation in the agricultural sector showed 11 influencing factors. The eleven factors are grouped into 2 clusters, namely cluster A consisting of 7 factors (age, education, experience, gender, income, land area, and parents), while cluster B consists of 4 factors (external factors, motivation, perception, and technology). There are three very dominant factors that influence the interest of the younger generation in the agricultural sector, namely income, education, and age.
