Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Liquid waste generated by hospital activities is a problem that must be faced by the hospital because the waste produced is infectious and toxic containing microorganisms, toxic chemicals, and radioactivity. If it is not carried out through a good management process, it will increase the risk of disease transmission, so that it can cause pollution to the surrounding environment and interfere with health. This study aimed to find out the characteristics of the liquid waste generated, and to examine the liquid waste management system carried out at the X Hospital in South of Sumatera. The research methodology used field surveys, literature studies, interviews and test analysis of the characteristics of liquid waste in the laboratory. The waste of the X Hospital in South of Sumatera comes from the activities of hospitals, outpatients, inpatients, emergency rooms, laboratories, laundry, nutrition, operating rooms, and offices. The liquid waste was processed through several stages, namely equalization tank, aeration tank, sedimentation tank, bioindicator tank, UV pool, and finally it was channeled at the outlet. The results of the water analysis showed that the parameters of temperature, PH, BOD, COD, TSS, and NH3, have met the Quality Standards of Hospital Liquid Waste that have been stipulated by the government. The process of managing liquid waste at the X Hospital in South of Sumatera has been carried out properly and in accordance with the Decree of the Minister of Health of the Republic of Indonesia Number: 1204/MENKES/SK/X/2004, namely the hospital has carried out its own wastewater treatment using a Wastewater Treatment Plant.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 924-930. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI). Liquid organic fertilizer is the result of overhaul or decomposition of organic matter, can come from animals or plants. Liquid organic fertilizer is made from damaged or rotten fruit and skin fruit (bananas, papayas, pineapples and a mixture of all three). So far, the hydroponic system uses inorganic nutrients or fertilizers (for example AB mix). This study aims to find out the effect of liquid organic fertilizers (POC) on the growth and yield of leaf vegetables (kale, spinach and caisim).This research used a hydroponic system, carried out from July to September 2021. This study used completely randomized design, with 8 treatments and 4 replications? The treatments were A = AB mix, B = liquid organic fertilizer from bananas, C = liquid organic fertilizer from pineapples, D = liquid organic fertilizer from papaya, E = liquid organic fertilizer from bananas and pineapples, F = liquid organic fertilizer from bananas and papayas, G = liquid organic fertilizer from pineapple and papayas, H = liquid organic fertilizer from bananas, pineapples and papayas. The results showed that liquid organic fertilizer had not been able to replace the AB mix solution, but there was hope liquid organic fertilizer could replace AB mix solution although the growth of spinach plants given POC leftover papaya fruit and POC fruit mixture (Pineapple + Papaya) shows growth, while caisim and kale plants show better growth than spinach plants. The remaining POC of pineapple fruit encourages the growth of caisim plants while poc of papaya fruit remains encourage the growth of kale plants

Get PDFDwintha SA, Aji HP, Haraki IM, Syahputri M, Rahman MAN, Puspitasari V. 2021. Botanical traps of clove leaf waste (Syzygium aromaticum) to control of fruitflies (Bactrocera spp.) on chili (Capsicum spp.). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 320-328. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The attack of fruitflies (Bactrocera spp.) on red chili plants is one of the most important problem in the red chili production process. Usually, farmers prefer the synthetic pesticides in controlling fruitflies. However, this method has a negative impact, such as resistance and resurgence of the target pest. This review aimed to provide information about the benefits of clove leaf residue's compounds as an innovation by the combined bioattractants through the application of botanical traps in controlling fruitflies. This writing method used an analyzed literature which developed into an understandable review. Clove leaf residue's extraction contained about 70-96 % methyl eugenol. Clove leaf residue's bioattractants could release volatile compounds containing methyl eugenol that was able to attract male fruitflies. The botanical traps system had the ability to attract fruitflies and could be used for a long time. The application of botanical traps caused disruption of sexual communication so that mating disorders occured in fruitflies. The conclusion is that methyl eugenol compound in clove leaf residue could be used as a bioattractant to replace synthetic attractants which combined with botanical traps
