Fruit flies (Drosophila melanogaster) generally have four phases in their life cycle, namely eggs, larvae, pupae and imago. In general, Drosophila melanogaster experiences a life cycle of 8-11 days at optimal temperatures. At lower temperatures the time required to complete its life cycle is relatively longer and slower which is around 18-20 days. Whereas at higher temperatures adult flies that grow will be sterile. The development period of Drosophila melanogaster in its life cycle is influenced by several factors, namely ambient temperature, food availability, level of maintenance density and light intensity. This study aims to determine the effect of temperature on the life cycle of fruit flies (Drosophila melanogaster). The study will be analyzed using quantitative analysis using randomized block design (RBD) with six temperature difference treatments for each treatment and repeated 4 times so that there are 24 experiments. The results showed the development in the Drosophila melanogaster cycle starting from Egg - Larva (Instar I) - Larva (Instar II) - Larva (Instar III) - Pre Pupa - Pupa - Imago. The life cycle of Drosophila melanogaster has an average of 42.08 hours or 1.75 days up to 79.96 hours or 3.33 days in each treatment. And obtained a fast time during the life cycle of Drosophila melanogaster at a temperature of 30°C is 10.47 days and the longest at a temperature of 18°C is 18.35 days.

Energy resources in Indonesia need to use alternative energy. According to the world energy board, energy use tends to increase by 50 percent by 2020. Indonesia is an archipelagic country that has vast and tropical waters and this makes indonesia has a high potential for developing renewable energy from macroalgae. Karapyak beach area is a coastal area in southestern west java that has abundant water biodiversity and high potential for the development of marine biotechnology. Abundant macroalgae in the karapyak beach is Gracilaria Sp, which can be used as biogas. Then this study was conducted to determine the potential of Gracilaria Sp, as an alternative material for biogas which would later become an alternative energy power plant. Biogas quality determination can be seen from the content of CO2, CH4, C2H5OH, dan CH3OH found in Glacilaria Sp. So that the potential for developing seaweed biogas electricity can be seen from the results of this study.

This study aims to determine the relationship between emotional intelligence and self-regulated learning of students in biology subjects in class XI MIPA SMA Negeri 1 Tasikmalaya. The research method used is a correlation. The population in this study was the entire class XI MIPA SMA Negeri 1 Tasikmalaya, amounting to 272 students. The research sample was taken using a purposive sampling technique as many as two classes, namely class XI MIPA 6 and XI MIPA 7 with 39 students who filled out the questionnaire. The data analysis technique used is a simple correlation test. The results of the study showed that there was a relationship between emotional intelligence and students' self-regulated learning. For the relationship between emotional intelligence and self-regulated learning, R is 0.568, which means it has a moderate level of relationship. The coefficient of determination of the emotional intelligence variable on the self-regulated learning variable is R2, which is 0.322, which means that the emotional intelligence variable contributes 32.3% to the self-regulated learning of students. Method, one of them by counseling approach of Cognitive Behaviour Therapy (CBT) using guided imagery technique.

Moon orchid is a member of the Orchidaceae family which is a seed plant and belongs to epiphytic orchids that attach to the host. Moon orchid is also one of the most popular orchids among the public because of the beauty of its large flowers and can last two to 4 months. However, the difficulty of re-flowering in moon orchid is one of the problems. This study aims to determine the growth of new shoots on the flowering of moon orchids (Phalaenopsis amabilis) through stimulation of shallots (Allium cepa L.) on the bud eye. This research is a quantitative research with true experiment method. Data obtained in the form of numbers of observations for 12 weeks. With simple random sampling technique. The population in this study were moon orchid plants that have roots, stems and leaves. This moon orchid plant is 3.5 years old and totalling 25 individuals. While the sample in this study is the second bud eye moon orchid plants from the base of the stem. There is an effect of shallot extract on the bud eye to stimulate the growth of new buds on the flowering of moon orchids. This study shows that there is an effect of shallot extract on the bud eye to stimulate the growth of new shoots on the flowering of moon orchids. There is the best concentration for the growth of new shoot height on the moon orchid is at a concentration of 40% with an average growth of 6.36 cm, while for the growth of new shoot diameter on the moon orchid is at a concentration of 30% with an average growth of 0.608 cm. Thus, the best concentration for the growth of new shoots on the flowering of moon orchids is between 30% - 40% concentration

Nepenthes mirabilis di Indonesia termasuk tanaman langka dan tanaman yang dilindungi termasuk dalam Convention on International Trade of Endangered Species (CITES) tanaman ini tergolong hampir punah dan langka. Potensi yang dimiliki Nepenthes mirabilis ini sangat besar, sehingga memerlukan adanya upaya konservasi untuk melestarikan Nepenthes mirabilis. Salahsatu upaya konservasi untuk perbanyakan tanaman Nepenthes mirabilis yaitu dengan kultur secara in vitro. Penerapan kultur in vitro merupakan solusi yang tepat untuk perbanyakan tanaman kantong semar (Nepenthes mirabilis) untuk tetap melestarikan keberadaannya. Penelitian ini dilakukan dengan tujuan untuk mengetahui pengaruh pemberian konsentrasi zat pengatur tumbuh BAP dan NAA untuk memacu terbentuknya kantong pada tanaman kantong semar (Nepenthes mirabilis) secara in vitro. Metode penelitian yang digunakan dalam penelitian ini adalah metode eksperimental nyata (True-experimental) dengan menggunakan rancangan acak lengkap (RAL) pola perlakuan faktorial yang terdiri dari 16 perlakuan dan diulang sebanyak 3 kali sehingga jumlah plot percobaan sebanyak 48. Konsentrasi BAP yaitu 0M, 4M, 8M, 12M dan konsentrasi NAA 0M, 0,5M, 1M, 1,5M. Parameter yang diukur yaitu jumlah daun, jumlah kantong, jumlah akar dan tinggi tanaman. Data yang diperoleh dianalisis menggunakan Analisis Ragam (Anova : Analysis of Variance) dengan tingkat kepercayaan 95% atau uji F dan dilanjutkan dengan uji Beda Nyata Jujur (BNJ) untuk mengetahui perbedaan antar perlakuan. Hasil penelitian menunjukkan bahwa interaksi antara BAP dan NAA dapat memacu terbentuknya kantong pada tanaman kantong semar (Nepenthes mirabilis) pada konsentrasi 8 M BAP dan 0,5 M NAA.
