Abstract

Di Indonesia kacang tanah umumnya ditanam di lahan kering (64%) dan selebihnya ditanam di lahan sawah irigasi setelah padi (36%). Kondisi tersebut menyebabkan kacang tanah berpeluang besar mengalami kekeringan pada sebagian maupun keseluruhan fase pertumbuhannya. Kekeringan pada fase vegetatif berpengaruh terhadap morfologi batang, daun, dan akar, tetapi tidak berpengaruh terhadap hasil. Kekeringan pada fase pembungaan hingga fase perkembangan biji (R1–R7) menurunkan jumlah bunga, menghambat pembuahan, perkembangan polong, dan biji sehingga menurunkan hasil 70–80%. Fase pertumbuhan R1–R7 merupakan fase kritis tanaman kacang tanah terhadap kekeringan. Penanaman varietas toleran kekeringan dapat mengurangi penurunan hasil. Varietas-varietas yang diketahui toleran kekeringan adalah Singa, Jerapah, Bison, Zebra, Sima, dan Talam 1.

Abstract

Plant population is one of key factors in crops yield. The determination of optimum population per area unit needs to be accommodated through the planting space arrangement. This study aimed to know the performance of some soybean genotypes planted with both single and double row planting pattern. The research was conducted in Kendalpayak Experimental Field, Malang from February to May 2017 arranged in split plot experimental design with three replications. The main plot was planting space consisting of single row (40 cm x 15 cm) and double row (60 cm x 20 cm x 15 cm), while the sub-plot was the soybean genotypes consisting of 12 promising lines (Grob/IT-7-7, Grob/Pander-397-6, Grob/IT-17-1, IBK/Argop-276-3, Grob/Pander-395-2, Grob/Pander-428-1, Grob/IT-7-5, Grob/IT-7-2, Grob/IAC-453-7, IBK/ Grob-296-10, Grob/IT-7-3, and Grob/IT-7-1) and 3 cultivars as comparison (Dena 1, Dena 2, and Grobogan). Each experimental unit was set in an area of 10.8 m2. Observation was performed on variables of plant height, number of fertile nodes, number of pods with three seeds, number of pods with two seeds, number of sterile pods, seeds dry weight, pod shells dry weight, weight of 100 seeds, and yields. The results of the research showed that each genotype performed different response to planting space depending on the characteristic of it. Yield obtained from double row planting space was 4.76% higher than that from single row planting space. There were 8 genotypes (Grob/IT-7-7, Grob/Pander-397-6, Dena 1, Grob/IT-7-5, Grob/IT-7-2, Grob/IAC-453-7, Grob/IT-7-3, and Grob/IT-7-1) which were able to produce seeds 2.0 ton/ha, either planted in single row or double row planting space.

Abstract

The current technological advances, making various informations easily spread throughout the world. It includes the entry of foreign culture (Westernization) into the Indonesian State. This westernization does not only have impact on politics, culture, region and technology, but in its development, westernization began to go into science. This research uses a literary study method, namely data collection activities by conducting a review of various books, literature, notes and reports realting to the topic discussed. As a result, it can be seen that knowledge Westernization occurs due to the development of shopist who generally have an impact on knowledge in the West. Knowledge in the West as a whole only relies on ratio in describing various things. So the process has strengthened the thesis of the knowledge Westernization. Knowledge in the West has the characteristic of removing the value of belief and spirituality, so this concept breeds secularization. Whereas secularization itself is not only a western worldview that is not Islamic, but also contrary to Islamic teachings. Secularization eliminates revelation as a source of knowledge and negates the  role of God in the scientific procces. This is what makes the knowledge Westernization increasingly clear.

Abstract

Study on soybeans morpho-physiological responses in artificial or natural shade are beneficial to determine the effects of shade on morpho-physiology and yield of soybean. This research was aimed to study the morpho-physiological responses of soybean varieties under shading of maize and cassava compared to arficial shading. The research was conducted in Kendalpayak Research Station, ILETRI, from February to May 2016 used split plot design with three replications. The main plot was three shade sources: N1:black paranet 50%, N2: maize shade, and N3: cassava shade, while the sub plot was five soybean varieties: Dena 1, Dena 2, Argopuro, Panderman, and Grobogan. Soybean varieties showed morpho-physiology differences depending on the shade source. Soybean grown under shading of cassava had plant height, leaf area ratio, and leaf area lower than under shading of paranet and maize. Cassava shade also caused soybean had higher growth rate, net assimilation rate, and yield than those under paranet and maize shade. Shade-tolerant varieties (Dena 1 and Dena 2) had high yield on all kind of shade. Less tolerant varieties (Panderman and Grobogan) had higher yield under cassava shade and lower yield under paranet and maize shade. Maize crop had similar shade effects with 50% paranet shade.Keywords: Glycine max (L) Merr., intercropping, Manihot esculenta Crantz, paranet, Zea mays L.
