Abstract

An experiment on respiration rate of German cockroach (Blattella germanica, Dictyoptera; Blattellidae) that had been resistant to pyrethroid insecticide was done from December 2012 to Mei 2013. This experiment used completely randomized design with two treatments (with insecticide and without insecticide exposured) and three replications. The respiration rate were measured using the Scholander Respirometer. The control subject were VCRU-WHO as a susceptible strain standarized by WHO, while the resistance strains were GFA-JKT, KRSA-BDG, PLZ-SMRD and PLZ-PDG consisted of female, male and nymph Individuals. The results shown that respiration rates were not significant difference between susceptible and resistance strains on females (F: 0.373, df: 4, P: 0.823), males (F: 0.562, df: 4, P: 0.696) and nymphs (F: 0.402, df: 4, P: 0.803). The respiration rate were also not significant difference between with insecticide and without insecticide exposured, except within GFA-JKT females (F: 9.161, df: 4, P: 0.039), VCRU-WHO males (F: 11.779, df: 4, P: 0.026) and GFA-JKT nymphs (F: 8.733, df: 4, P: 0.042). Those results support that resistant cockroach do not increase respiration rate in responding insecticide exposured. Keywords: German cockroach, respiration rate, strains, insecticide exposured

Abstract

A marked increase in demand for white mice (Mus musclulus L., mammals) in the Indonesian market has been attributed to the price soar, while the availability of mice with a standardized quality remains very limited. Considering such condition, a business focusing on standardized farm of white mice should be actively socialized to younger people thereby elevating their enthusiasm in the entrepreneurship. This community service program aimed to provide insights as well as to train the basic skills in white mouse farming for students of the National High School Number 5 Bukittinggi. The program has been carried out for one day in the Biology Department, Andalas University with 45 participants. We deployed the lectures and hands-on practice on the aspects of white mouse farming. All participants have directly practiced various principle techniques in mice farming such as handling, sexing, mating, and raising brooders. This activity has increased the interest of the participants in such creative business. In the future, some efforts should be made to ensure the sustainability of the program by involving the participants from other schools, teachers and unemployed youth in West Sumatra.

Abstract

The city of Padang produces approximately 600 tons of waste daily, which includes the categories of recyclable and non-recyclable waste. However, the percentage of waste that can be recycled is only about 17% and the rest must be heaped into end landfill every day. The category of recycled waste is counted as much as 65% is organic waste that is made into compost and 35% is both plastic and paper waste that is processed into other products. Maggot, which is the larva of the Black Soldier Fly, is an organic matter-decomposing agent that has better decomposition capabilities than other organisms. Maggot has biomass with high protein and fat content. Maggot farming is the most appropriate effort needed by the community today, because in addition to processing daily organic waste, it will also produce feed for livestock such as chicken, duck, fish, and bird. The farming process only requires simple technology and low cost, but is able to reduce the earth's waste load. The Andalas University community service team provided training on maggot farming to process organic waste from community households. The training was carried out using the Hybrid method, which is a combination of offline and online techniques with the same goal. The activity began with counseling on theoretical explanations, followed by both the farming practices and further program assisting. It hopes that the activity will be improved by other trainings such as Maggot’s processing into more valuable products, so that it can be packaged in such a way as to be marketed to the target purchasers.

Abstract

The maggot of Black Soldier Fly (BSF) is an alternative protein substitute in poultry feed. Growing maggot is an easy activity and valuable in the bioconversion of household organic waste. Maggot farming cages can be integrated with poultry cages. The integrated cages between maggots and poultry will save space and operational costs. Therefore, the workshop about integrated cage between maggot and poultry was urgently needed for poultry farmers in Padang, West Sumatra. The workshop delivered theory and direct practice of making integrated cages with community partners. The activity was held from October to November 2021 for poultry farmers in Koto Panjang Limau Manis village, Pauh District, Padang. Integrated cages are a solution for poultry farmers interested in maggot cultivation as an alternative feed for their poultry. Partners need support from universities in transferring science and technology because the integration cage is the first time implemented in Kota Padang. In addition, government support is also needed in regulating waste sorting and processing so that the community's organic waste can be converted to valuable products using maggot.

Abstract

The German cockroach is a common pest worldwide that has developed insecticide resistance. Eco-enzyme with an aromatic aroma is one alternative way to prevent insecticide resistance development and repel the German cockroach population. This study aims to determine the value and level of repellency of orange peels' eco-enzyme. The method of this study is a Repellency test of four concentrations of eco-enzyme to the reared resistant German cockroach. The repellency level of eco-enzyme at low concentrations (10%) to high concentrations (100%) ranges from high repellent to very high repellent at one hour of observation. The repellency decreases until 48 hours of observation and ranges from medium to high repellent. Eco-enzyme solutions that are eco-friendly, simple to make, and low in toxicity to humans can use as an alternative to synthetic repellents.

Abstract

The Bukit Nobita Tourism Area is being developed by Kelurahan Kampung Jua Nan XX, Kota Padang, in collaboration with FMIPA UNAND, one of which is the Department of Biology. Nowadays, a waste management program is being designed. This program is similar to the existing Bank Sampah mission in Bukit Nobita, but Bank Sampah only manages inorganic waste, leaving organic waste problems unresolved. As a result, the team from the Department of Biology of FMIPA UNAND proposed processing organic waste with black soldier fly maggots (Hermetia illucens). The cultivation training of maggots was carried out in this program in collaboration with Pokdarwis, the PKK group, and MBKM students. The activity occurred at the Kantor Lurah Kampung Jua Nan XX and the Minagot Sumbar Maggot BSF Research and Cultivation House, Kota Padang. The program was held from November to December 2022. The cultivation of Black Soldier Fly maggots by the community in the Bukit Nobita tourism area is expected to convert organic waste into organic fertilizers, the maggots can be processed into animal and fish feed, and it can also become an educational attraction that provides an exciting experience for visitors to the Bukit Nobita Tourism Area.

Abstract

The continuous cell line known as T47D cells originates from the isolation of epithelial cells from the ductal breast tissue of a 54-year-old woman with metastatic breast cancer. Numerous plant species have been employed in alternative anti-breast cancer therapy, showing advancements in recent years. The aim of this systematic review is to assess the potential bioactive compounds from herbal plant extracts and analyze the effects of herbal plants on T47D breast cancer cells. This research employs a systematic approach to gather articles, encompassing related research questions, chosen databases, keyword selection, inclusion and exclusion criteria, as well as outcomes and conclusions regarding the collected articles. From the reviewed articles, several plants exhibit anti-breast cancer activity on T47D cell lines, namely Calamintha incana, Sterculia quadrifida, Psidium guajava, Uncaria nervosa, Syzygium aqueum, Capsicum annum, Bauhinia scandens, Lansium domesticum, and Garcinia cowa due to their content of bioactive compounds such as triterpenoids, alkaloids, phenolics, flavonoids, saponins, and tannins. These bioactive compounds from the plants exert significant influence on cell cycle, proliferation, fatty acid synthesis, and apoptosis of cancer cells.
