Sistem kontrol akan menampilkan volume air dan nutrisi yang perlu ditambahkan setiap hari untuk menjaga pertumbuhan sayur bayam yang baik. Tipe nutrisi yang digunakan adalah tipe AB Mix yang banyak tersedia dipasaran. Metode yang digunakan adalah metode simulasi, dimana sistem terdiri dari 2 bahan utama nutrisi yaitu larutan X dan larutan Y yang ditambahkan dengan air sumur. Rasio dari 3 bahan ini berubah dapat berubah setiap minggu selama siklus pertumbuhan. Sistem akan terus memantau konsentrasi larutan dan ketinggian level nutrisi, serta persediaan air dan persediaan nutrisi X dan Y. Karena sistem dirancang untuk diluar ruangan, maka proses penyinaran akan terjadi secara alami. Sistem ini harus mampu menyediakan nutrisi yang memadai dan jumlah air yang cukup serta interaksi yang paling minimum dengan operator. Setelah siklus pertumbuhan selesai maka sistem selalu siap untuk mula...

This Green Tuff rock is a type of sedimentary rock formed from volcanic ash released from a pit during a volcanic eruption. This research uses the gravimetric method which is analytical chemical method by weighing the sample that has been melted as much as 0.5 grams then adding enough distilled water, 10 ml of HCl and 5 ml of HNO3, after that it is heated to dry and added 5 mL of HCl. Reheat until the volume becomes half of the initial volume and added distilled water afterwards, cooled and filtered. The purpose of adding HCl and HNO3 is so that the silica content can be separated from the impurities so that a larger crystal-shaped silica precipitate and a yellowish-colored solution containing impurities are present in the precipitate. So that in this study the results of the analysis of the content of Silica dioxide (SiO2) of 76.50%.

Demam merupakan kondisi suhu tubuh lebih besar dari suhu 37,5 o C. Demam adalah bagian dari proses kekebalan tubuh melawan infeksi akibat parasit, virus, dan bakteri. Penelitian penentuan nilai kalor jenis tanaman herbal jahe dan temulawak ini dilakukan dengan menggunakan metode eksperimen temperatur Cobra3 HYPWE. Hasil penelitian pada tanaman herbal jahe diperoleh nilai kalor jenis rata-rata sebesar 51,46 J/gr o C dan nilai kapasitas kalornya adalah 1.092,2 J/ o C; serta temulawak dengan nilai kalor jenis rata-rata 46,17 J/gr o C dan nilai kapasitas kalornya adalah 923,4 J/ o C. Semakin besar nilai kalor jenis yang diperoleh, maka semakin besar pula nilai kapasitas kalor yang terdapat dalam bahan tersebut dan semakin baik pula dalam menurunkan suhu.

This study used a procedure to compare blood pressure before and after exposure to sound sources from the press. Fifteen respondents measured blood pressure between the ages of 20-40 years during working hours using a digital blood monitor. The average measured sound seriousness is 107.8 dB in the room where the sound source is made and 99.1 dB in the room directly adjacent to the sound source. Blood pressure measurements showed that blood pressure increased more in 15 respondents. For example, Respondent 4 who is located next to the noise source has a systolic blood pressure of 20.62% and a diastolic blood pressure of 15.96%, whereas Respondent 1 is located next to the noise source. There is a problem, the percentage increase. With blood pressure. Low blood pressure Systolic blood pressure of 7.48% and diastolic blood pressure of 6.08%.

The study was conducted with survey and laboratory analysis to calculate the number of ruminants, corn, and rice stalk using supporting data from the South Sulawesi Statistics office. Amounts of 84,567, 112,915, and 3,579 ruminants have been raised in Maros, Gowa, and Makassar, respectively. While 6,757, 9,529, and 50 monogastric are raised in Maros, Gowa, and Makassar. Corn and rice stalks were produced 465,878.06 tons year-1 in Gowa and Maros. Every cattle and equine can produce feces up to 25 kg day-1 and 30 kg day-1, daily feces production equals 2,316,885; 3,108,745; and 90,975 kg day-1 in Maros, Gowa, and Makassar, respectively. These waste products can be converted to biogas as source of green energy with a total yield of 667,752,675,489.20 x 103 cc. Its production ratio is 1 kg dry matter...
