Indoor agriculture has begun in urban areas. With the narrowness of land and the model of vertical house development, makes this method of indoor agriculture has become a trend in several big cities in the world. Meanwhile, the one that is always needed by every plant is photosynthesis, and every natural photosynthesis of plants continually requires abiotic components of visible light from sunlight. That's why the indoor agriculture requires a replacement source of the sun with artificial sunlight. We can make this artificial sunlight from several light sources, such as incandescent lamps, compact fluorescent lamps (CFL), or the latest with Light Emitting Diode (LED). In this paper, we measured the intensity of light generated from several LEDs with some radiation distance to obtain the optimal energy for plants photosynthesis.

The study aimed at investigating the antibacterial activity of ethanol extracts of the lempuyang Gajah (Zingiber zerumbet (L.) Smith) rhizome against S. enteridis ATCC 31194 and S. typhimurium ATCC 23564. An experimental method was employed for testing the antibacterial activity, with a completely randomized design (CRD) of factorial patterns. Factor I, ethanol concentrations which consisted of 45%; 70% and 95%, while factor II was the concentration of extracts, i.e 0%; 2.5%; 5%; 7.5% and 10%. The results showed that extraction with 45% and 70% ethanol, Z. zerumbet contained alkaloids, tannins, terpenoids, and saponins; however, the-95%-ethanol did not result any saponins, but flavonoids instead. Meanwhile, the chromatogram patterns of all extracts showed zerumbone is a dominant compound. It was concluded that the Z. zerumbet (L.) Smith extracts with 95% ethanol solvent, and 10% concentration had the highest antibacterial properties against S. enteritidis.

Nawala Mangsa is a weather station system owned by the Computer Science Faculty of Narotama University. The system has been installed in several locations and is used to monitor the temperature and relative humidity of the site for research purposes. All information from the remote, currently stored in the server online via an internet connection. In this latest version (ver-2.0), Nawala Mangsa had some updates, including the use of Raspberry Pi 3 boards, adding a sensor to measure sunlight illumination (TSL2561), and replacing temperature and humidity sensor with BME280 so it can also measure air pressure. The using of a board that equipped with Bluetooth version 4.1, which is Bluetooth Low Energy (BLE) ready, make this version of this Nawala Mangsa can also broadcast the data that are read by the sensor through BLE, in addition to sent to the server over the TCP/IP network. By this way, so the weather station data can be directly read by the mobile device that equipped with BLE observer.

This research aims to investigate the substitution pattern of nucleotide base and haplotype diversity of Indonesian swamp buffalo (Bubalus bubalis) based on the mitochondrial DNA cyt b partial gene sequence. 17 samples were chosen from 7 different regions with each uniquely represents Indonesian biogeography which comprise Aceh, Riau, Madiun, Blitar, Lombok, South Borneo and Tana Toraja. The result of cyt b gene sequence alignment showed the presence of transition and transversion substitutions and the absence of insertion and deletion. The amount of transitions was found to be higher than that of transversions and the amount of substitution in pyrimidine was also higher than that in purine. The highest amount of transitions happened in base TàC which is a silent substitution. The result of median joining network analysis showed that Indonesian haplotype Bubalus bubalis could be classified into 16 haplotypes which form different haplogroups unique to their geographical region. The result of median joining network analysis also indicated that the genetic relationships of swamp buffaloes (Bubalus bubalis) in Indonesia are highly influenced by their geographical locations.

ABSTRAKPenelitian ini dilakukan untuk memanfaatkan suatu tanaman air Azolla sp. yang memiliki mikrosimbion mikroalga (ganggang) Anabaena azollae., yang dikembangkan sebagai formula imbuhan pakan (feed additive) pada pakan ayam pedaging (broiler). Formula imbuhan pakan ini adalah untuk pakan komplit ayam pedaging, baik fase starter maupun finisher. Hasil penelitian menunjukkan bahwa pemberian imbuhan pakan Azolla sp. yang bersimbiosis dengan A. azollae pada pakan jadi merk Malindo yang diujikan untuk ayam pedaging strain Hubbard, baik fase awal (starter) dan kemudian fase akhir (finisher) memberikan performa Pertambahan Bobot Badan Harian (PBBH) ayam broiler strain Hubbard sebesar 52,42 gram/ekor. Sedangkan pencapaian bobot badan akhir rata-rata sebesar 1,880.95 gram/ekor. Baik pertambahan bobot badan harian maupun pencapaian bobot badan akhir secara umum masih dalam kisaran sebagaimana disarankan, demikian pula konsumsi pakannya. Tetapi, kandungan kolestrol daging broiler perlakuan menunjukkan penurunan hingga perlakuan level 2 %. Berdasarkan hasil penelitian maka dapat disimpulkan bahwa Azolla sp. yang bersimbiosis dengan mikroalga A. Azollae dapat digunakan sebagai imbuhan pakan pada pakan komplit ayam pedaging dengan tidak memberikanefek terhadap penurunan palatabilitas maupun metabolisme, dan juga sumber bahan pakan ini merupakan non konvensional, sehingga hal ini merupakan potensi yang dapat dikembangkan untuk masa mendatangkan dengan meningkatkan efisiensi pakan dan kemampuan produksi ayam broiler.Kata kunci : Azolla sp.; Anabaena azollae; broiler; Hubbard; imbuhan pakan

This study aims to determine the length of time the irradiation of LED lights is suitable for aquascape ornamental plant performance, fish survival and water quality in aquascape media. This research was conducted on 22 April 28 May 2019 in collaboration with Fisheries Faculty of Agriculture, Animal Husbandry, University of Muhammadiyah Malang. This research uses 2 types of low light aquascape plants, namely Cryptocorine Wenti and Hidrocotyle Leucepala. This research is an experimental study using RAL with 4 treatments P0 (control 12 hours of indirect sunlight), P1 (LED lights with a long exposure time 8 hours), P2 (LED lights with a long exposure time of 10 hours), P3 (LED lights with a long exposure time of 12 hours) repeated 3 times. The parameters observed include aquascape ornamental plants such as plant length, stem diameter, wet weight. In the observation of water quality including temperature, pH, DO, dissolved CO2, and water hardness. In aquascape ornamental fish in the form of survival rate and growth of ornamental aquascape fish. Analyzed with ANOVA and continued with the Least Significant Difference Test on parameters that obtained significant differences.The results showed that the irradiation time of 10 hours had a significant influence on the stem diameter of the plant, namely P (0.037) <0.05 and the LSD test showed that the length of time the irradiation of 10 hours of LED lights had a significant effect on the diameter of the aquascape stem. In the length and wet weight of aquascape ornamental plants did not show significantly different results. On the parameters of water quality, growth and graduation of fish life also did not show significantly different results from the treatment of the long exposure time given.
