Development of Pratylenchus Coffeae in Biochar Applied Soil, Coffee Roots and Its Effect on Plant Growth

Biochar improve physical, chemical and biological properties of soil. It may also be used as botanical pesticides. The experiment was aimed to determine the effect of biochar on population development of parasitic nematode Pratylenchus coffeae. The experiment was carried out in Nematology Laboratory and in a greenhouse of Indonesian Coffee and Cocoa Research Institute (ICCRI), Jember, Indonesia. The experiment was arranged according to completely randomized design with six treatments of biochar concentrations, i.e. 4%; 3%; 2%; 1%; 0.5% and 0% dry weight of soil. Research results revealed that biochar application of 4.0% was effectively killed 74.5% of P. coffeae, while the lowest mortality level of 37.5% at biochar 0.5% treatment. In the greenhouse trial, application of biochar 4.0% was the most effective in suppressing the population of parasitic nematode in coffee seedlings. Application of biochar was also able to increase the growth and biomass of coffee seedlings

Evaluasi Pemilihan Supplier Terbaik Menggunakan Metode Taguchi Loss Functions Dan Analytical Hierarchy Process Di PT Indomaju Textindo Kudus

PT Indomaju Textindo merupakan produsen karung plastik yang menggunakan kalsium sebagai salah satu bahan bakunya. Saat ini terdapat 4 supplier kalsium, sementara masing – masing supplier memiliki performansi yang berbeda. Untuk itu Perusahaan menginginkan evaluasi terhadap masing – masing supplier. Penelitian ini bertujuan mengidentifikasi kriteria - kriteria yang menjadi pertimbangan di dalam pemilihan supplier dan melakukan pembobotan terhadap kriteria-kriteria tersebut, menentukan nilai loss function masing – masing supplier dan yang terakhir menentukan supplier kalsium terbaik. Metode yang digunakan untuk mengevaluasi supplier adalah Taguchi Loss Function dan Analytical Hierarchy Process (AHP). Taguchi Loss Function digunakan untuk menghitung loss function masing-masing supplier, sedangkan AHP digunakan untuk membobotkan masing-masing kriteria. Kriteria pemilihan supplier dari penelitian ini adalah harga, kualitas, proses pengiriman dan pengepakan dengan bobot untuk masing-masing kriteria secara berturut-turut adalah 29%, 54%, 11% dan 6%. Besarnya loss function yang dibebankan pada Perusahaan akibat ketidaksesuaian terendah adalah dari supplier Indomaju, sehingga supplier ini yang, sehingga supplier yang memberikan kerugian minimum bagi Perusahaan yaitu supplier Indomaju. Kata kunci : kalsium, supplier, Taguchi Loss Function, Analytical Hierarchy Process PT Indomaju Textindo is a woven bag producer which used calcium as one of raw material in the production. In this time there are 4 calcium, whereas each of supplier have different performance, so the company want to evaluate their suppliers. Objective of this research are indentifing of criterions in supplier selection process and wight of the criterions, determining loss function value of the each suppliers and chosening the best supplier. This research used Taguchi Loss Function dan Analytical Hierarchy Process (AHP) for determining the best supplier. Taguchi Loss Function for calculating loss function each of supplier, while AHP for wighting aech of criterion. Criterion of the supplier selection are price, quality, delivery process and packaging, with wight for each criterion are 29%, 54%, 11% and 6% successively. The lowest value of Loss function is owned by Indomaju supplier's, so its given minimum loss for the company

Peningkatan Kemampuan Berpikir Kreatif melalui Penerapan Guided Inquiry Dipadu Brainstorming pada Materi Pencemaran Air

Creative thinking ability is the individual imagination to solve problems. Low creative thinking ability causes students find difficulties in resolving problems faced in learning. Guided inquiry combined with brainstorming is an alternative solution to improve creative thinking ability, give students freedom to think to solve the problem. Creative thinking ability developed consists of fluency, flexibility, originality and elaboration. The purpose of this research was to improve creative thinking ability of students through guided inquiry combined with brainstorming on water pollution material. This research was a classroom action research, held in May 2016. The subjects were students of class X private high school in Karanganyar, with total of 41 students. The research data were obtained through observation, interviews, documentation, and testing. The main data source of creative thinking was from the result of test which was compiled based on aspects of creative thinking by Munandar. The validity of the data was confirmed through triangulation techniques. The data analysis was done through descriptive analysis techniques. The increase of fluency, flexibility, elaboration, and originality aspect was 10.3%, 8.6%, 11.87% and 14.4%, respectively. Conclusion of the research is that there was an increased creative thinking ability from pre-cycle to the first cycle in the form of an improvement category from less creative to quite creative category.

Pemurnian Selulosa-α Hasil Hidrolisis Pelepah Sawit Menggunakan Enzim Xylanase dengan Variasi PH dan Sumber Enzim Xylanase

Midrib palm is one of the waste that produced from palm farming which contain alpha cellulose about 35%. The component of alpha cellulose could be used as a raw material for nitrocellulose if it is has more than 92% of purity. So to increase the purity of alpha cellulose, midrib palm has to be treated by purifying step. In this time, chemical still be choices to be material for purify alpha cellulose, while as we know that chemical has a bad impact for our envirotment. So it is important to search another purifying agent and it is xylanase. Xylanase is one of enzyme that has an ability to break up the link between xylose in xylan. So the purpose of this research are to use xylanase as another purifying agent, to know what is the best pH for this purifying process and to compare the result between two xylanases that produced from different fungi. Before start the purifying step, midrib have to through extraction step to remove all extractive and continue with hydrolisis step by using extraction liquid of palm empty bunch ash. Then after that purifying step can be done at 600C for 1,5 hours by making some differences at pH (4,5 and 6). The highest purity of alpha cellulose was reached at pH 6 by using xylanase from Aspergillus Niger about 97,55%. So the conclucion of this research are, the best pH for purifying process by using xylanase is 6 and the best xylanase is the one which produce from Aspergillus Niger. Beside that, the use of xylanase which is comes from the same species will be not affected much to the purifying result
