Abstract

IPB CP1 potato is a raw material for potato chips. The advantage of IPB CP1 potatoes is their high yield. Challenges in potato production are limited areas with optimal altitude and condition as well as low quality and quantity of seeds. Utilizing a mid-altitude area for potato cultivation is one of the solutions to increase potato seed production. This study aimed to compare the growth and production of IPB CP1 G0 seed tuber in a greenhouse and screenhouse in mid-altitude with different numbers of shoot cuttings per polybag. This research was conducted with two factors. The first factor is the use of growth plant houses, i.e. greenhouse and screenhouse. The second factor is the number of shoot cuttings per polybag, i.e. 2 and 3 shoot cuttings per polybag. Growth parameters observed included plant height, number of nodes and leaves, and fresh and dry weight of shoots. The production parameters observed included the number as well as fresh and dry weight of tubers. The growth and production of IPB CP1 potatoes grown in the greenhouse were better than those grown in the screenhouse. The number of cuttings per polybag did not affect the growth and production of IPB CP1 potato.

Abstract

Arabic learning conducted at MTsN 3 Ponorogo has several obstacles including writing and sound grammar, so learning Arabic is considered a difficult and boring subject. The problem of sound and writing is a problem that usually arises in learning Arabic for non-Arabs, as well as experienced by class VIII students at MTsN 3 Ponorogo. This research is a qualitative descriptive study that describes Arabic learning activities with the research subjects namely teachers, students and the object of this research is Arabic subjects. The problems of learning Arabic include educator factors, student factors, method factors, media factors and learning evaluation factors. Efforts must be made to include educational training, provide understanding and motivation to students and choose appropriate teaching methods.

Abstract

ABSTRACTCultivation of eggplant (Solanum melongena L.) needs fertile soils to optimize the yield,however since the fertile land become limited, cultivation of eggplant needs to utilize sub optimal landssuch as salin soils. The objective of the research was to analyze morphological and physiologicalresponses of six eggplant genotypes (collection of the Center for Tropical Horticulture Studies), todetermine the tolerance of genotypes to salinity stress to be used as tolerant parents in eggplantbreeding program. The research was a factorial experiment. It was designed as randomized blockdesign with two factors, which were genotype factor (6 genotypes) and salinity factor (0, 2-4, 5-7, 8-10 mS cm-1) with 5 replications. The research was conducted in greenhouse using pot. Themorphological evaluation included shoot length, number of leaves, fruit weight, number of branches,shoot biomass, root biomass, and the physiological characters included photosynthesis rate,transpiration rate, stomatal conductance, CO2 intercelluler, leaf relative water contents, and prolineaccumulation. The results showed that salinity stress decreased all morphological as well asphysiological characters in all genotypes, except for proline accumulation that showed increase asthe salinity increase. Based on the stress susceptivility index (SSI), there was no eggplant genotypesclassified as tolerant to salinity. However, there were two eggplant genotypes, i.e., number 061 and072, classified as moderat genotypes to salinity stress.Keywords: proline, sensitive, stress susceptibility index, tolerantABSTRAKBudidaya terung (Solanum melongena L.) membutuhkan tanah yang subur untukmengoptimalkan hasil panen, namun karena lahan subur menjadi terbatas, maka dalam budidayaterung memerlukan pemanfaatan lahan suboptimal seperti tanah yang bersifat salin. Tujuan penelitianini ialah untuk menganalisis respon morfologi dan fisiologi enam genotipe terung, yang merupakanterung hasil koleksi Pusat Kajian Hortikultura Tropika, untuk menentukan toleransi genotipe terhadapcekaman salinitas yang akan digunakan sebagai tetua toleran pada program pemuliaan tanaman terung.Penelitian ini merupakan percobaan faktorial yang dirancang menggunakan rancangan acak kelompokyang terdiri dari dua faktor yaitu faktor genotipe dengan 6 genotipe dan faktor perlakuan salinitas(NaCl) yang terdiri atas 4 taraf yaitu 0-1, 2-4, 5-7, 8-10 mS cm-1) dan diulang sebanyak 5 kali.Penelitian dilakukan di rumah kaca sebagai percobaan pot. Karakter morfologi yang diamati adalahtinggi tanaman, jumlah daun, bobot buah, jumlah cabang, bobot basah tajuk, bobot basah akar,sedangkan karakter fisiologis adalah laju fotosintesis, laju transpirasi, konduktansi stomata, CO2interselular, kandungan air relatif daun, dan akumulasi prolin. Hasil penelitian menunjukkan bahwacekaman salinitas menurunkan semua karakter morfologi dan fisiologis pada semua genotipe, kecualiakumulasi prolin yang menunjukkan peningkatan seiring meningkatnya cekaman salinitas.Berdasarkan indeks kepekaan cekaman (SSI), tidak ada genotipe terung yang tergolong toleranterhadap salinitas. Namun, ada dua genotipe terung, yaitu: 061 dan 072, tergolong genotipe moderatterhadap cekaman salinitas.Kata kunci: indeks kepekaan cekaman, proline, sensitif, toleran
