Judul: Analisis Keragaman Morfologi Koleksi Tanaman Kopi Arabika dan Robusta Balai Penelitian Tanaman Industri dan Penyegar Sukabumi
Abstrak: Coffee (Coffea sp.) is one of the plantation plant which have become commodities that counts in national income strengthening. This study aimed to identify and analyze the morphological diversity characters of arabica and robusta coffee genotypes collection in Sukabumi Industrial and Freshener Crops Research Institute. The experiment was conducted by characterization of 11 genotypes the coffee using a descriptors list which have been modified for the coffee plants. Most of the quantitative data were analyzed by analysis of covariance and others analyzed by analysis of variance. Qualitative and some of quantitative data were analyzed by analysis of quantitative data to get a dendogram clusters. The results of the morphological identification of arabica and robusta coffee plant showed some real differences between the genotypes both the variables that can be combined or can not be combined. The results of the dissimilarity relation dendogram shows the level of the coffee plant arabica and robusta coffee kinship approximately 0.45 (45%) of the observed variables. Robusta coffee has a higher level of similarity than arabica coffee.

Judul: Identification of Various Accessions of Arabica Coffee (Coffea arabica) Based on Morphological Characters in Small Holder’s Garden, Cikajang District, Garut Regency
Abstrak: Kopi (Coffea sp.) merupakan komoditas perkebunan yang berperan penting dalam kegiatan perekonomian di Indonesia. Umumnya buah kopi Arabika berwarna merah saat matang, namun salah satu kopi yang tumbuh di lahan petani Garut berbuah kuning dan diduga berasal dari tetua kopi berbuah merah, tetapi identitas tetuanya tidak diketahui. Penelitian bertujuan mengidentifikasi berbagai aksesi tanaman kopi Arabika dan menganalisis kekerabatan kopi Arabika berbuah kuning dan berbuah merah melalui karakter morfologi di Kebun Rakyat, Kecamatan Cikajang, Kabupaten Garut. Penelitian dilakukan pada bulan Januari hingga Juli 2022. Lokasi penelitian bertempat di tiga blok Kebun Rakyat, Desa Margamulya, Kecamatan Cikajang. Percobaan dilakukan dengan cara mengidentifikasi karakter morfologi setiap aksesi menggunakan descriptor list IPGRI untuk tanaman kopi yang dimodifikasi. Data kuantitatif dianalisis menggunakan uji ANOVA dan uji lanjut DMRT pada taraf 5%. Data kualitatif dan sebagian data kuantitatif dianalisis menggunakan analisis cluster untuk melihat kekerabatan antar aksesi menggunakan program NTSYS 2.11a. Berdasarkan hasil identifikasi, terdapat delapan aksesi kopi Arabika dengan tiga warna buah yang berbeda yaitu kopi berbuah kuning (A1), berbuah merah (A2, A3, A4, A5, A6, A7) dan berbuah oranye (A8). Hasil dendogram menunjukkan terdapat kekerabatan antara A1 yang berbuah kuning dengan A2 yang berbuah merah pada tingkat kemiripan 75% berdasarkan karakter morfologi yang dimilikinya, Coffee (Coffea sp.) is a plantation commodity that plays an important role in economic activities in Indonesia. Generally, Arabica coffee cherries are red when ripe, but one of the coffees that grows on Garut farmer's land bears yellow fruit and is thought to have come from a red fruit coffee parent, but the identity of the parent is unknown. The aims of this study were to identify various accessions of Arabica coffee plants and to analyze the kinship of Arabica coffee with yellow fruit and red fruit through morphological characters in the Small Holder's Garden, Cikajang District, Garut Regency. The research was conducted from January to July 2022. The research location was located in three blocks of the People's Garden, Margamulya Village, Cikajang District. The experiment was carried out by identifying the morphological characters of each accession using the IPGRI descriptor list for the modified coffee plants. Quantitative data were analyzed using the ANOVA test and the DMRT follow-up test at the 5% level. Qualitative data and part of the quantitative data were analyzed using cluster analysis to see the kinship between accessions using the NTSYS 2.11a program. Based on the identification results, there are eight accessions of Arabica coffee with three different fruit colors, namely coffee with yellow fruit (A1), red fruit (A2, A3, A4, A5, A6, A7) and orange fruit (A8). The dendogram results showed that there was a kinship between A1 with yellow fruit and A2 with red fruit at a 75% similarity level based on their morphological characters

Judul: Durability of Specific Immunoglobulin (Ig) Y Againts Influenza and Covid-19 in Sunscreen
Abstrak: The benefit of specific immunoglobulin Y (Ig Y) as an active ingredient in personal care products such as sunscreen has not been properly studied. Our study aims to evaluate the reliability of specific IgY against influenza and the COVID-19 virus in a sample sunscreen product. Specific IgY influenza and COVID-19 viruses were inserted in the sample sunscreen at two concentrations of 0.1% and 0.25%. Three treatments were observed: control (C) sunscreen without IgY, treatment 1 (T1) sunscreen with 0.1% IgY, and treatment 2 (T2) sunscreen with 0.25% IgY. Organoleptic observations were carried out to monitor changes in aroma, color, and texture, and sunscreen sampling was done every week for 6 weeks. The durability of IgY was evaluated using an enzyme-linked immunosorbent assay (ELISA) and a neutralization assay. Organoleptic observation from weeks 1 to 6 showed consistency in its aroma, color, and texture. Enzyme-linked immunosorbent assay and neutralization assay (NA) results of the T1 and T2 groups showed negative results except for sample T1 at week 5, which showed a positive result in the Influenza A ELISA. Based on the results, it seems that IgY concentrations of 0.1% or 0.25% were not optimal. However, this negative result might be due to low concentration of the IgY and the presence of beeswax, which inhibits IgY and causes it to dissolve in distilled water, thus preventing it from being detected in the assay.
