Judul: Telaah Mengenai Niat Menggunakan Jasa Laundry Kiloan pada Mahasiswa dengan Pendekatan Theory of Planned Behavior
Abstrak: Niat berhubungan dengan rencana dan keinginan konsumen untuk membeli produk/jasa tertentu, serta jumlah unit produk/jasa yang dibutuhkan pada periode tertentu. Penelitian ini bertujuan untuk menganalisis pengaruh dari karakteristik contoh, sikap, norma subjektif, dan kontrol perilaku terhadap pembentukan niat menggunakan jasa laundry kiloan pada mahasiswa dengan pendekatan Theory of Planned Behavior (TPB). Penelitian ini menggunakan desain cross-sectional study dengan metode non probability sampling dan teknik accidental sampling. Contoh dalam penelitian ini yaitu 100 mahasiswa program S1 IPB yang menggunakan dan tidak menggunakan jasa laundry. Data dikumpulkan menggunakan kuesioner yang diisi langsung oleh contoh. Hasil uji korelasi Pearson menunjukan bahwa usia memiliki hubungan negatif signifikan dengan sikap. Sikap terhadap penggunaan jasa laundry, norma subjektif, dan kontrol perilaku memiliki hubungan positif sangat signifikan dengan niat menggunakan jasa laundry. Hasil uji regresi linier berganda menunjukkan bahwa uang saku memiliki pengaruh positif signifikan terhadap niat menggunakan jasa laundry, sedangkan norma subjektif dan kontrol perilaku memiliki pengaruh positif sangat signifikan terhadap niat menggunakan jasa laundry.

Judul: Analisis niat pembelian produk melalui Online Shop pada Mahasiswa dengan pendekatan Theory Of Planned Behavior
Abstrak: Perkembangan internet memberikan dampak positif pada bidang perdagangan yang ditandai dengan lahirnya online shop. Sekarang ini, banyak online shop yang berkembang di Indonesia dengan berbagai macam bentuk seperti sebagai media perantara yang mempertemukan penjual dan pembeli di dunia maya. Tujuan penelitian ini adalah menganalisis pengaruh sikap terhadap perilaku, norma subjektif, dan kontrol perilaku yang dipersepsi terhadap niat pembelian di online shop. Penelitian ini mengggunakan design cross sectional-study dengan contoh sebanyak 100 mahasiswa Pascasarjana (S2) IPB yang tercatat aktif sebagai mahasiswa tahun ajaran 2013/2014. Teknik penarikan contoh penelitian ini adalah purposive sampling yang diambil secara proporsional dari 4 fakultas terpilih. Hasil penelitian menunjukkan bahwa karakteristik contoh yang memiliki hubungan dan pengaruh terhadap variabel Theory of Planned Behavior (TPB) adalah pendapatan, intensitas akses internet, jumlah sumber informasi, dan jumlah alasan membuka website. Sikap terhadap perilaku, norma subjektif, kontrol perilaku yang dipersepsi, dan niat pembelian saling berhubungan dan memengaruhi sesuai yang dihipotesiskan. Jadi, dapat dikatakan bahwa penelitian ini sesuai dengan Theory of Planned Behavior., the birth of online shop. Nowadays, many online shops grow in Indonesia on many forms such as online media that bring together the sellers and buyers in virtual world. The purpose of this study was to analyze the influence of attitudes toward behavior, subjective norms, and perceived control behavior toward purchase intentions through online shop. This research used cross-sectional design with 100 postgraduate students (S2) of IPB who are active as a student of 2013/2014 academic year. Sampling technique of this study was purposive sampling taken proportionally from 4 selected faculties. The result showed that the sample’s characterisric who have correlation and influence toward the Theory of Planned Behavior (TPB) variables were income, internet access intensity, mount of information resources, and mount of reasons to access the website. Attitude toward behavior, subjective norm, perceived control behavior, and purchase intention were interconnected and influenced appropriate with the hyphotesis. So, it can be said that this study was consistent with TPB

Judul: Merremia dennstedt ex endlicher (Convolvulaceae) in Sumatra.
Abstrak: Merremia is a small genus in the family Convolvulaceae. Merremia is a perennial or annual herb or woody liana with stems creeping or twinning on trees or rocks, put out milky white sap when injured and some species with tubers. Merremia is often confused with genus Ipomoea, due to they have resemblance in funnel shaped or campanulate corolla and straight anther. Phenetically, some members of Merremia have yellow flower whereas Ipomoea has white, purple or purplish white. Merremia is also confused with Operculina due both have non-spinulose pollen and dehiscent capsule. Nevertheless, Operculina characterized by circumciselli capsule and Merremia characterized by valve capsule. The important character in Merremia is the spread of the hairs on corolla that can be easily observed at the mature flower bud. The genus Merremia is found in the tropical regions of both hemispheres. Merremia wildly distributed throughout the tropical regions of Asia, Africa, Australia, North and South America and approximately there were 80 species of Merremia in the world. A Total of 175 sheets (164 collection numbers) which are deposited in Herbarium Bogoriense, 97 sheets (95 collection numbers) which are deposited Andalas University Herbarium (ANDA) and 9 sheets (4 collection numbers) which are deposited in BIOTROP Herbarium (BIOT) were studied. It composed of all specimens of Merremia in Sumatra. Additional specimens were collected by the author 28 sheets (15 collection numbers) from North Sumatra, West Sumatra and Lampung, which are stored in BO and BIOT. The digital data that consist of type specimens and distributions of species from JSTOR Plant Science and Convolvulaceae Unlimited were also used here. All the hebarium specimens were studied based on their morphological characters following de Vogel (1987) and Rifai (1976). The terminology of morphological characters followed Lawrence (1955), Veldkamp (1987), Harris and Harris (1994), Hickey and King (2005) and Stearn (1983). Information on the habitat, ecology, distribution, vernacular names and uses were noted from the specimens label and literatures. Taxonomic studies in Sumatra were conducted. There are eight species, one subspecies, one varietas and two forma from nine previously species (M. cissoides, M. dissecta, M. emarginata, M. hirta, M. peltata, M. quinquefolia, M. tridentata, M. tuberosa and M. vitifolia), two subspecies (M. umbellata ssp. orientalis and M. tridentata ssp. hastata), one varietas (M. boisiana var. sumatrana) and two forma (M. hederacea f. pubescens and M. hederacea f. barbata) can be recognized. One species (M. tridentata) and subspecies (M. tridentata ssp. hastata) are excluded because they have been proposed to different new taxa Xenostegia by Austin and Staples. The existence of M. emarginata was noted as new record in Sumatra and M. cissoides was noted as new record in Indonesia. A phylogenetic analysis using PAUP*4.Ob10 was undertaken based on morphological characters, using Evolvulus nummularius and Porana volubis as the out group. The phylogenetic analysis used 35 morphological characters was resulted consistency index (CI) = 0.60, homoplasy index (HI) = 0.40, retention index (RI) = 0.56 and Rescaled consistency index (RC) = 0.34. Phylogenetic tree used morphological characters divided taxa into two groups. The separation support M. boisiana var. sumatrana, M. cissoides, M.
