Judul: Economic Pressures, Coping Strategies, and  Quality of Life of Single Father Families during The Covid-19 Pandemic.
Abstrak: Keluarga ayah tunggal rentan dengan permasalahan ekonomi di masa pandemi Covid-19. Strategi koping dibutuhkan sebagai upaya untuk meningkatkan kualitas hidupnya. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik keluarga, tekanan ekonomi, dan strategi koping terhadap kualitas hidup pada keluarga ayah tunggal selama pandemi Covid-19. Penelitian ini menggunakan metode penelitian kuantitatif dengan desain cross sectional study yang melibatkan 60 ayah tunggal yang dipilih secara purposive sampling. Hasil penelitian menemukan bahwa hampir dari separuh ayah tunggal memiliki tekanan ekonomi objektif dan subjektif sedang, sebagian besar ayah tunggal memiliki strategi koping rendah, sedangkan hampir separuh ayah tunggal memiliki kualitas hidup sedang. Uji korelasi menunjukkan bahwa tekanan ekonomi objektif dan subjektif berhubungan negatif dengan kualitas hidup, sedangkan pendapatan per kapita dan strategi koping berhubungan positif dengan kualitas hidup. Uji regresi menunjukkan bahwa tekanan ekonomi subjektif berpengaruh negatif terhadap kualitas hidup, sedangkan strategi koping berpengaruh positif terhadap kualitas hidup., Single father families are vulnerable to economic problems during the Covid 19 pandemic. Coping strategies are needed to improve their quality of life. This study aims to analyze the influence of family characteristics, economic pressures, and coping strategies on the quality of life of single father families during the Covid-19 pandemic. The research used a quantitative research method with a cross-sectional study design involving 60 single fathers selected by purposive sampling. The results found that almost half of single fathers had moderate economic pressures, almost all single fathers had low coping strategies, and almost half of single fathers had moderate quality of life. Correlation test showed that objective and subjective economic pressures are negatively related to the quality of life, while per capita income and coping strategies are positively related to quality of life. Regression test showed that subjective economic pressure had a negative effect on the quality of life while coping strategies had a positive effect on the quality of life.

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.
