Abstract

Penelitian ini adalah penelitian deskriptif yang bertujuan untuk mengetahui kemampuan isolat bakteri penambat nitrogen yang diisolasi dari rhisosfer tanaman padi dan jagung asal Kabupaten Takalar dalam memproduksi zat pengatur tumbuh IAA dan pelarutan posfat. Isolasi bakteri penambat nitrogen dilakukan menggunakan medium selektif bebas nitrogen yaitu Ashby dan Burk’s. Koloni bakteri yang tumbuh dan menunjukkan perbedaan karakteristik dipilih kemudian dikarakterisasi secara fisiologi dan morfologi. Kemampuan menghasilkan IAA dari isolat bakteri dianalisis dengan menggunakan metode spectrophotometry pada panjang gelombang 535 nm. Uji kemampuan pelarutan posfat secara kuantitatif dilakukan pada medium Pikovskaya dengan membandingkan rasio antara diameter koloni dengan diameter zona bening yang terbentuk. Dari hasil isolasi bakteri diperoleh 20 isolat bakteri penambat nitrogen dimana 6 isolat diantaranya terdeteksi mampu memproduksi zat pengatur tumbuh IAA dengan konsentrasi antara 7.35-38.35 ppm. Dari 6 isolat yang mampu memproduksi zat pengatur tumbuh IAA, 2 isolat diantaranya terdeteksi mampu melarutkan posfat dengan rasio zona bening 1,7 cm-2,6 cm sedangkan empat isolat diantaranya tidak memiliki kemampuan dalam melarutkan posfat.

Abstract. This study is an experimental research that aims to find out how the response of corn growth (Zea mays) with urea-coated zeolite as nitrogen release slowly, implemented from April to December 2017. The making of fertilizer is done in Biology Laboratory of East III Floor Department of Biology Faculty of Mathematics and Natural Sciences of Makassar State University. The cultivation and maintenance of maize was conducted at Greenhouse of Ecophysiology of Seraca Crops Research Institute (Balitsereal) Maros and Analysis of nitrogen data at Soil Laboratory of Agricultural Technology Assessment Institute (BPTP) Regency. Maros South Sulawesi. This research used Randomized Block Design (RAK) 3 grouping with Control, Urea, Phosphate, Potassium (UPK), UPK Zeolite 10%, UPK Zeolit 30%, and UPK Zeolit 50%. The corn variety used was HJ 21 Agritan. Observation parameters were stem circumference, leaf chlorophyll content, plant biomass (root, stem and leaves), cob weight, ear length, seed weight, leaf nitrogen and seed nitrogen. The technique of data origin is done by using variance analysis technique (F test) / ANOVA at the level of trust α = 0,05%. Then proceed with Duncan's advanced test using SPSS statistic program 20. The results showed that there was an interaction between zeolite-coated urea fertilizer on the yield of cob and corncob with different results on the other treatment. The best results on urea-coated zeolite treatment with 10% concentration. While for stem circumference, leaf chlorophyll content, plant biomass (root, stem and leaf), seed weight, leaf nitrogen and seed nitrogen showed no effect but when viewed the average result of urea coated application of zeolite with the highest 30% concentration.Keywords: The growth of corn, the application of urea zeolite coated, slow release fertilizersp., Thalassiosira sp., Probiotic Bacteria

Abstract

Abstract. The growth rate of Hermetia illucens larvae in the bioconversion of organic waste is influenced by the media and environmental conditions where the BSF lives. This study aims to determine the effect of the feed formula on the growth of Hermetia illucens larvae in the bioconversion of organic waste. This research method was carried out by rearing BSF larvae, making BSF feed formulas, determining larval length, determining the weight and weight of BSF cassava. The results showed that the feeding formula from fish waste, tapioca waste with a chopped diameter of 10,20,30 mm gave a significant effect on the growth of BSF larvae (larval length, larvae weight) and BSF maggots. The provision of 20 and 30 percent fish waste has a higher weight and length with a chopped diameter of 20 and 30 mm..Keywords: feed formula, hermetia illucens, bioconversion, organic waste

Abstract. Slaughterhouses (RPH) produce large amounts of solid waste every day and have not been utilized optimally. RPH solid waste has great potential to be used as plant fertilizer through the composting process. Composting is expected to change the organic material composition of the abattoir solid waste to be more ideal to support plant growth. This study aims to determine the chemical composition of compost made from waste at RPH Tamangapa Makassar City before and after the composting process. Composting from solid waste at Tamangapa RPH Makassar was carried out using the main ingredients, namely rumen contents (treatment I) and rumen contents mixed with livestock manure in a ratio of 1:1 (Treatment II). The composting process was carried out in a compost box with a size of 40x40x60 cm with a passive aeration system for 4 weeks with three replications. Quantitative data tested in this study included the content of N-total (%), C-Organic (%), P-total (%), K-total (%), C/N ratio, organic matter (%), water content (%) and compost reduction (%). The results showed that the content of elements C, N, P, K, C/N ratio, organic matter, and water content before composting in both treatment I and treatment II were generally still low and almost the same as the raw materials. After the composting process took place, the content of C, P, K, C/N ratios generally showed an increase, while the N content was relatively constant. The results of the analysis showed that there was no significant difference between the chemical composition of the compost in the treatment and both before and after the composting process.Keywords: RPH solid waste, composting process, chemical composition of compost, C/N ratio.

Abstract

Adding the nutritional content of broth powder without destroying the distinctive taste of the broth can be done using pure mushroom extract and additional vegetables and spices. This study aims to determine the organoleptic characteristics and identify the chemical functional groups of glutamic acid in the best samples of oyster mushroom broth powder added with vegetables and spices. The results of the organoleptic test were tabulated in a table and then analyzed using a descriptive test. The organoleptic characteristics of the best color parameters were in treatment B1 which had a pale white color . The best treatment of aroma, texture, and taste parameters were found in the B2 treatment with a characteristic aroma of typical broth, fine powder texture, and has a distinctive taste of broth. The identification of the functional groups of secondary metabolites using the Fourier Transform Infrared (FTIR) instrumentation. Identification results with FTIR showed absorption at wave number (cm-1): 3419.74, 2934.62, 1639.56, 1409.70, 1055.55. There is N-H, O-H, C-H, C=O carbonyl group and carboxylic C-O, which identify the presence of amide compound, phenol acid, alkane, aldehydes, amid I and carboxylic acid, which are known as glutamic acid in this sample. Keywords: Organoleptic, Functional Groups Identification, Oyster Mushroom Broth Powder Why only B1 that you mentioned in color parameters?

Abstract

Abstract. Slaughterhouse waste is generally disposed into the environment without being processed, so that it potentially causes air pollution, water pollution, and soil pollution. Slaughterhouse waste can be processed and used as plant fertilizer through the composting process. This study aims to compare the composting performance of solid waste at Tamangapa RPH Makassar between the main ingredient consisting of rumen contents only (treatment I) with that consisting of a mixture of rumen contents with livestock manure (treatment II). We recorded quantitative data including temperature (0C), pH, material mass reduction and composting time and qualitative parameters including color, smell and texture of the resulting compost. The composting process was carried out in a compost box with a size of 40x40x60 cm with a passive aeration system for 4 weeks with three replications. Our results demonstrated that treatment I and treatment II had a similar pattern of temperature changes, while the average pH of treatment I was higher compared to treatment II. Based on the composting performance data including changes in temperature and pH from the first week to the fourth week of composting, we concluded that both treatments resulted in a rapid composting process with good-quality compost.Keywords: composting performance, RPH solid waste, composting process, rumen contents, passive aeration.
