Abstract

Dengue Hemorrhagic Fever (DHF) has still one of the problem diseases in Indonesia. There has increased in dengue cases in several parts of Indonesia since January 2020 and in the midst of the COVID-19. Very little information about natural breeding sites of Aedes especially of the phytotelmata such as Bambusa sp., Neoregelia spectabilis, Musa paradisiaca, and Cocos nucifera. Other than physical factors of plants, it is suspected that there are attractive compounds produced by these plants. The purpose of this study was to determine the chemical compounds that are attractants from plants used as breeding sites for Ae. albopictus. The research method was started by observation of the presence of Neoregelia spectabilis, Musa paradisiaca, Bambusa sp., and Cocos nucifera plants which contained Ae. albopictus on one of the plant body parts found. Then macerated, purified and analyzed for chemical content using GCMS. The results showed that there were differences in the chemical compounds of plants. The dominant chemical compound is tetracosane. Tetracosane is a chemical compound from the Alkane group. The alkana is an important role in plant interactions such as attractants in the oviposition of certain insects or as attractants for insect feeding activities.

Abstract

Pineapple (Ananas comosus L.) is a fruit belonging to the Bromeliaceae family. The pineapple plant (Ananas comosus L.) contains bromelin enzyme which can be used as a substitute for the enzyme renin (rennet) as a milk coagulant agent. This research aims to determine the effect of pH and temperature on the speed of the bromelin enzyme's ability to coagulate milk, as well as determine the best pH and temperature on the speed of the bromeline enzyme's ability to coagulate milk. This research uses a factorial with a Completely Randomized Design (RAL-F) pattern consisting of 2 factors, the first factor is pH (K), K1 = pH 6 (acid) ̸ test tube; K2 = pH 7 (neutral) ̸ test tube; K3 = pH 8 (alkaline) ̸ test tube. Furthermore, the second treatment is temperature (D), D1 = temperature 60°C ̸ test tube; D2 = temperature 40°C ̸ test tube; D3 = temperature 50°C ̸ test tube. Each factor consists of 3 treatment levels, the total number of treatment combinations is 9 and each treatment combination is repeated 3 times. The results of the research show that there is an influence between providing variations in pH and temperature on the speed of the bromelin enzyme's ability to coagulate milk. The fastest average speed of milk coagulation time was in the K2D3 treatment (pH 7 temperature 50°C), namely 19.33 minutes, so it can be said that the best treatment was the pH and temperature in the K2D3 treatment (pH 7 temperature 50°C).Bahasa Indonesia Abstract:Nanas (Ananas comosus L.) merupakan salah satu buah yang termasuk dalam famili Bromeliaceae. Tanaman nanas (Ananas comosus L.) mengandung enzim bromelin yang dapat dijadikan sebagai pengganti enzim renin (rennet) untuk agen koagulan susu. Penelitian ini bertujuan menentukan pengaruh pH dan suhu terhadap kecepatan kemampuan enzim bromelin dalam koagulasi susu, serta menentukan pH dan suhu terbaik terhadap kecepatan kemampuan enzim bromein dalam koagulasi susu. Penelitian ini menggunakan faktorial dengan pola Rancangan Acak Lengkap (RAL-F) yang terdiri atas 2 faktor, faktor pertama yaitu pH (K), K1 = pH 6 (asam) ̸ tabung reaksi; K2 = pH 7 (netral) ̸ tabung reaksi; K3 = pH 8 (basa) ̸ tabung reaksi. Selanjutnya, perlakuan kedua yaitu suhu (D), D1 = suhu 60°C ̸ tabung reaksi; D2 = suhu 40°C ̸ tabung reaksi; D3 = suhu 50°C ̸ tabung reaksi. Masing-masing faktor terdiri atas 3 taraf perlakuan, jumlah total kombinasi perlakuan sebanyak 9 dan setiap kombinasi perlakuan diulang sebanyak 3 kali. Hasil penelitian menunjukkan bahwa terdapat pengaruh antara pemberian variasi pH dan suhu terhadap kecepatan kemampuan enzim bromelin dalam koagulasi susu. Rata-rata kecepatan waktu koagulasi susu tercepat terdapat pada perlakuan K2D3 (pH 7 suhu 50°C) yaitu 19.33 menit, sehingga dapat dikatakan bahwa perlakuan terbaik adalah pH dan suhu pada perlakuan K2D3 (pH 7 suhu 50°C).

Abstract

Continuous chemical control of rat pests (Rattus spp.) can sometimes lead to resistance and resurgence problems, and even some cases of inaccurate targeting ultimately killing livestock. The idea of ​​​​repelling rats in rice fields using vibrations of crickets and other natural animals transmitted via radio has been done and the results are quite optimal for rat control, but it has not been done in corn cultivation. The purpose of this study was to determine the effect of cat sound audio on the intensity of rat pest attacks (Rattus spp.) in corn (Zea mays L.) plantations. The research location was in a farmer's land owned by a farmer in Dagan Village, Solokuro District, Lamongan Regency. Determination of sampling points using the diagonal method, each into 5 sub-observation plots. In each sub-plot, markers were placed as sampling points. Audio with cat and bird sounds was played continuously from 05.00 pm - 07.00 am. Observations were conducted at 7:00 a.m. at all sampling points at 30 and 60 days after planting. Observations were conducted for three days using audio and three days without audio. Damage symptoms were observed directly at each sampling point. Corn plants showing symptoms were then recorded and analyzed using the Damage Intensity formula. Observations showed that the use of cat sound audio was able to reduce the level of rat infestation. At 30 days after planting, the damage percentage was reduced by 8.33%. Meanwhile, at 60 days after planting, the damage percentage was reduced by 18.33%.
