Judul: Tungau Ektoparasit pada Ular Micropechis ikaheka, Leiophyton albertisi, dan Stegonotus sp. di Papua
Abstrak: Symbiosis is an interaction between two species or more. In snake, ectoparasite mites were found in the external parts of the body such as beyond the ventral scales of the snake. Previous exploration showed that the snakes M. ikaheka, L. albertisi and Stegonotus sp. in Papua was found as the host of ectoparasites mites. However, there is lack of species information of the mites. Thus, this research were aimed to study the ectoparasite mites of snakes M. ikaheka, L. albertisi and Stegonotus sp. in Papua. Wholemount polyvinillactophenol slide dan Scanning Electron Microscope (SEM) were prepared for mites identification. Results showed that the ectoparasites mites on M. ikaheka, L. albertisi and Stegonotus sp. were clasified in Subclass Acari, Order Parasitiformes, Family Paramegistidae, Genus Ophiomegistus, and Species Ophiomegistus luzonensis. Characteristics of mites O. luzonensis has nine pairs of setae on the jugular shield, two setae on metapodal shield. The metapodal shields were unfused and those shields were separated with the peritreme shield, endopodal shield verge with latigynial shield, latigynial and sternogynial shield was separated. Latigynial shield possessed more than twenty pairs of setae, however, on mesogynial–ventrianal shield had more than one hundred simple foliate setae. The mesogynial and ventrianal shield were fused and occurred three rows of foliate setae.

Judul: Phylogeography and Species Limits in the Papuan White Snake (Micropechis ikaheka) (Reptilia: Serpentes: Elapidae)
Abstrak: Papua white snake, Micropechis ikaheka, has been distingushed into two subspecies M.i. ikaheka and M.i. fasciatus. However, due to lack of data on their morphology, distribution and ecology, both subspecies often ignored in scintific discussions and refers only byas , Micropechis ikaheka. This study was designed to document the differences between M.i. ikaheka and M.i fasciatus by using scales characteristics and reproductive organ or hemipenes. The study also examine, zoogeography, habitat, diet and cannibalism of both subspecies to better understanding the the ecology of one of the most venomous snakes in the world. This study consists of three topics with method and also different in the size samples, respectively. The first study is the histology and microtopography of the skin were studied using paraffin method and Scanning Electron Microscope (SEM). The second is the hemipenis were examined by following Myers and Cadle (2003), and Zaher and Prudente (2003). The third is the abdominal surgery was carried out to document diet type and the investigate phenomenon of cannibalism in the snake. Specimens for this study came from the collection from Museum Zoologicum Bogoriense (MZB) and Universitas Negeri Papua’s Laboratory (LZU). The research result also indicated that the markers of skin and hemipenis described the same structure and microornamentation in all M. ikaheka groups being compared. Based specimens examined morphological descriptions do not s support the further differentiation in Micropechis. In short, two markers that used in this study could not sufficiently indicate the differences in the level of species and subspecies of M. ikaheka. The study, however, were able to delineate zoogeography and skin color patterns, which fall into four groups: M. i. ikaheka; M. i. fasciatus. M. i. ssp. “intermediate”; and M. i. ssp “black”. This study also revealed that color variations did not overlap in their geographic distribution. It is therefore, it suggested that environmental factors may contribute to the skin color variations. It also assumed that habitat discontinuous and biogeography factors may also cause the loss of the connection between the original populations (vicarians) or follow colonization events (dispersal). The examined of 22 stomach contents of M. ikaheka shows this species is carnivorous, and prey on vertebrates such as amphibians, fish, reptiles, and Mammals. These snakes are opportunistic predators since they prey on all that can be captured, but mainly reptiles (61.5%), followed by mammals and fish (both 15.4%), and amphibians (7.7%). Although categorized as terrestrial animal, the diet study showed that M. ikaheka snakes often go into the water to hunt for fish (the sample from Yapen island), including eel (the sample from Aru island). Based on prey items indentified, there is evidence that M. ikaheka is cannibal. At this time, there still no record on reason for cannibalism, but it is assumed that cannibalism was due to competition between populations and means to control population.

Judul: Analisis Strategi Pemasaran 4C Kafe Cerita Kopi dalam Upaya Meningkatkan Penjualan di Masa Pandemi hingga New Normal
Abstrak: Terjadinya pandemi Covid-19 pada awal tahun 2020 mengakibatkan omzet penjualan Cerita Kopi turun drastis. Selain itu, penerapan strategi pemasaran yang belum optimal menyebabkan Cerita Kopi terus megalami penurunan omzet hingga era new normal. Oleh sebab itu dibutuhkan strategi pemasaran yang lebih efektif untuk meningkatkan penjualan Cerita Kopi. Penelitian ini bertujuan menganalisis strategi pemasaran yang sudah dilaksanakan Cerita Kopi dengan membandingkan strategi pemasaran kafe lain (Due Café), dan mengidentifikasi faktor-faktor yang mempengaruhi tingkat penjualan Cerita Kopi menurut persepsi konsumen berdasarkan bauran pemasaran 4C (co-creation, currency, communal activation, dan conversation), sehingga dapat dirumuskan perbaikan strategi pemasaran yang lebih efektif. Pengolahan data pada penelitian ini menggunakan anlisis deskriptif, benchmarking, dan bauran pemasaran 4C.
