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 Perilaku Penggunaan Tas Belanja pada Ibu Rumah Tangga Tidak Bekerja Menggunakan Theory of Planned Behavior.
Abstrak: Penggunaan tas belanja merupakan salah satu perilaku ramah lingkungan yang masih perlu didorong. Penelitian ini bertujuan menganalisis pengaruh karakteristik contoh, sikap terhadap perilaku, norma subjektif, kontrol perilaku, dan niat terhadap perilaku penggunaan tas belanja berdasarkan theory of planned behavior. Penelitian ini menggunakan desain cross sectional study. Lokasi yang dipilih secara purposive adalah Desa Cijujung dan Kelurahan Panaragan. Contoh dalam penelitian ini adalah 100 ibu rumah tangga. Data dikumpulkan melalui wawancara meliputi variabel karakteristik contoh dan variabel dalam theory of planned behavior. Hasil penelitian menunjukkan bahwa sikap terhadap perilaku, norma subjektif, kontrol perilaku, dan niat termasuk dalam kategori sedang. Berdasarkan hasil uji korelasi, terdapat hubungan yang positif dan signifikan di antara variabel sikap terhadap perilaku, norma subjektif, kontrol perilaku dengan niat serta di antara variabel niat dan perilaku. Hasil uji regresi menunjukkan bahwa kontrol perilaku berpengaruh positif signifikan terhadap niat. Frekuensi penggunaan tas belanja dipengaruhi secara positif oleh niat, norma subjektif, dan kontrol perilaku serta dipengaruhi secara negatif oleh sikap terhadap perilaku.

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.
