Abstract

Sludge is a suspension of liquid waste and microorganisms originating from the Wastewater Treatment Plant (WWTP). The humus and nutrient content of sewage sludges can be used as compost by the vermicomposting mechanism. This study aims to determine the potential of sewage sludge in the Integrated Laboratory of UIN Sunan Gunung Djati Bandung as a raw material for making organic fertilizer through vermicomposting by utilizing the earthworm Eisenia fetida. The media containing a mixture of cow dung (CD) and sludge (S) was divided into four treatments consisting of Control (100% CD), P1 (75% CD + 25% S), P2 (50% CD + 50% S), and P3 (25% CD + 75% S) with the weight of each medium is 500 grams. A total of 20 adult earthworms (5-6 grams/20 heads) were added to each treatment medium for the vermicompost process for 8 weeks. The results showed that the composition of the media in treatment P1 showed the highest effect on the quality of vermicompost with percentages of C (42.62), N (1.85), P (1.21), and K (0.26) based on the SNI 7763-2018 standard. The conclusion of this study is that the sewage sludges from the Integrated Laboratory of UIN Sunan Gunung Djati Bandung can be used as raw material for making organic fertilizer with an optimum media composition of 75% CD + 25% S.

Abstract

Adenomyosis is a benign invasion of endometrial tissue into the myometrium and it is one of the cause of abnormal uterus bleeding (AUB) in women. Adenomyosis is not widely discussed because the incidence and prevalence are not well known due to the certainty of diagnosis depending on histological examination which requires prior hysterectomy. This literature review aims to improve further understanding of adenomyosis by discussing two focus studies, which is to discover other diagnostic methods, and to be aware of the different ways to treat adenomyosis with different published literature in various database as the references.  Advances in imaging technology allows more non-invasive procedure such as transvaginal ultrasound (TVUS) and magnetic resonance imaging (MRI) to diagnose adenomyosis without comprimising the patient fertility. The treatment of adenomyosis are divided into two parts, medicamentosa and operative therapy. Although there is different ways to diagnose and treat adenomyosis in this era, histological examination and hysterectomy is still the gold standart and definitive therapy to diagnose and treat adenomyosis, respectively.

Abstract

Cucumber (Cucumis sativus L.) has a fairly good nutritional content and is in great demand by the public. Cucumber production in NTT continues to increase, but it is still low when compared to national production data. One of the efforts made is to use liquid organic fertilizers that are cheap and easy to get around us because they come from natural ingredients, namely plant residues or animal remains. Lamtoro leaf extract (Leucaena leucocephala, Ssp) is an organic fertilizer made from plants that is environmentally friendly. In addition to the fertilization factor, pruning activities are also needed to increase the weight of cucumber production. Pruning is a common cultivation action to limit excessive vegetative growth in plants so that nutrients or nutrients can be absorbed by the parts of plants that need them optimally. These nutrients can be provided by lamtoro leaf extract, then pruning is also carried out in order to reduce photosynthetic competition in order to increase cucumber production. Based on this description, it is felt that it is necessary to conduct research on the effect of giving concentration of lamptoro leaf extract and pruning on cucumber plant production. The purpose of this study was to determine the interaction of giving lamptoro leaf extract concentration and pruning on cucumber plant yields. This research was conducted from May to June 2022. This study was arranged using a randomized block design (RBD) in a factorial pattern with two factors. The first factor was the application of lamtoro leaf extract fertilizer consisting of four levels, namely: L0: control (without lamtoro leaf extract), L1: 400 cc of lamtoro leaf extract liter of water-1 plot-1, L2: 450 cc of lamtoro leaf extract liter of water-1 plot-1, L3: 500 cc of lamtoro leaf extract liter of water-1 plot-1. The second factor is pruning (P) consisting of three treatment levels, namely: P0: No pruning, P1: Pruning one leaf and one branch on segments 6–12, P2: Pruning two leaves and two branches on segments 6–12. The results obtained: administration of 500 cc of lamtoro leaf extract liter of water-1 plot-1 and pruning of two leaves and two branches on segments 6–12 of cucumber plants had a very significant effect on cucumber plant yields, concentration of 500 cc of lamtor leaf extract lamtoro liter of water-1 plot-1 and pruning two leaves and two branches on 6–12 plant nodes produced the best growth and yield of cucumber plants, the interaction between lamtor leaf extract and pruning resulted in plant length 79.33, fruit weight 284.83 g, fruit length 30 cm and fruit diameter of 4.48 cm. Recommendation: for cucumber cultivation, it is better to use POC of lamtor leaf extract 500 cc of lamtoro leaf extract liter of water-1 plot-1 and pruning of two leaves and two branches on internodes 6-12 plants. There needs to be further research on the use of POC concentrations of lamtoro leaf extract with higher concentrations to reduce the use of inorganic fertilizers.

Abstract

Closed house waste which has so far been considered a contributor to environmental pollution if processed professionally, can be reused as a component of non-ruminant rations. The purpose of this study is to determine the production (potential, quantity, and quality) of broiler farm waste that is maintained in a closed house system. The cost of production of non-ruminant livestock (pig) 70-80% is still occupied by the cost of feed. The price of commercial concentrate is relatively expensive, which is a reason to look for alternative feed sources. The discovery of potential closed house chicken farm waste and innovative products as a source of protein in rations for non-ruminant (pig-poultry) is expected to the feed problem. Innovative product protein concentrate chicken farm waste of closed house (WCH) system that is cheap and competitive is produced through three stages of research: identify the type and availability of waste, its nutrient content, formulate various protein concentrate formulas, and small-scale tests on pigs with metabolic cage to determine metabolized energy content and digestibility. The results showed that the type of closed house waste (WCH) that has the potential as alternative animal feed is the waste of dead-refused chickens, and litter mixed with scattered feed. Production data in 4 periods of rearing, obtained the number of dead and rejected chickens weighing 850.7 kg (212.7 kg/period), and litter weight of 4000 kg (1000kg/period). Nutrient content of flour mixed with closed house waste (WCH), protein: 36.58%, crude fat: 4.42%, gross energy Kcal/gram. aboratory test of WCH was negative for Eschericia colli and Salmonella shigella, Coliform < 3.0 CFU/g, mold 200 CFU/g. The conclusion of this study is that the waste from closed house (LCH) broiler farms has the potential as a source of protein in alternative feeds for rumonants (chicken and pig).
