ABSTRACT

Palm oil nurseries are the starting point that really determines the process and result of palm oil’s growth in the field. The fertilization process and using the right planting media can have a positive influence for the seedling growth process. This research aims to determine the effects of providing various types of LOF and planting media on the growth of palm oil’s seedling in pre-nursery step. This research was carried out at KP2 Institut Pertanian STIPER Yogyakarta which located in Wedomartani, Ngemplak, Sleman, Daerah Istimewa Yogyakarta from March until June 2023. This study used a completely randomized design (CRD) method. The first factor was the different types of LOF which consisted of babana peels, coconut water and fruit waste. The second factor was the planting media that consisted of soil, soil : compost, and soil : rice husk with each planting media having the same ratio of 1 :1. The data result of this research were analyzed using ANOVA at 5% of real level, if there was a significant difference with the result then used the DMRT test with the range was 5% too. The results of this research showed that the application of various LOF types and planting media had the same effect for the plam oil seedling growth in pre-nursery steps. There was no real interaction between the provision of different LOF types and planting media on the palm oil seedling growth in pre-nursery steps. The use soil:compost has a positive effect on the growth of seedlings compared to the others.

Traversing the Waste Spectrum: Unveiling Pakistan's MSW Landscape and Solutions

Tue, 31 Oct 2023 00:00:00 +0700

Municipal solid waste (MSW) management must be sustainable in order to meet the Sustainable Development Goals (SDGs) and address health, environmental, and disposal challenges caused by the vast amounts of trash generated. MSW management going wrong puts locals in danger. In Pakistan, the production of municipal solid trash is rising daily. Urban settlers and other organizations gather a lot of waste in various forms, usually defiling and making our surroundings uninviting. Due to the indiscriminate dumping of various wastes, the soil quality in the metropolitan area has decreased as a result of solid and liquefied waste disposal. Significant environmental concerns regarding soil and water pollution arise from transferring contaminated garbage and mixed fluid outside of waste disposal borders. The impacts of municipal garbage disposal on soil and water quality at open waste dumping sites were the main focus of this review. Using a soil and water quality index, in many regions of the world especially in regions where waste management practices are insufficient, the contamination of soil and water owing to incorrect municipal solid waste disposal is a serious environmental hazard. Open dumping, unregulated landfilling, and illegal dumping are examples of improper waste disposal practices that can result in pollution that affects the quality of the soil and water. They must also seek to identify sustainable waste management solutions. The effect of these emitted gaseous emissions has, however, been thoroughly researched. To safeguard the environment and public health, quick action must be made to control trace element pollution.

Tilapia fish are susceptible to the process of decay, within 2 hours after death the tilapia fish will experience a decline in physical quality. Starfruit extract contains active compounds, namely saponins, triterpenoids and several minerals which are antibacterial substances. This research aims to determine the effect of starfruit extract on the total microbial test, water content and pH of tilapia during room temperature storage. Data analysis used a Completely Randomized Design (CRD). Data were analyzed descriptively for total microbial testing using the Indonesian National Standard calculation method SNI 2332.3-2015 and SNI 01-2346-2006. The differences in treatment in this study were made by differences in the concentration of starfruit extract. The concentration of starfruit juice given was 0 gr (P1), 40 g (P2), 60 gr (P3), 80 gr (P4) and 100 gr (P5) with four repetitions. The samples were then stored at room temperature for 8 hours. Based on the research results, it can be seen that starfruit extract has an influence on the total microbial value, Based on the research results, it can be seen that starfruit extract has an influence on the total microbial value, pH value and water content value of tilapia fish. The number of bacterial colonies in the treatment with the highest amount of extract (100 grams) with the lowest total microbial value was 2.49 x 105 colonies/g. Also, the pH value and water content of all treatments given starfruit extract were still included in the standards for fresh fish.

Every day the traditional market produces garbage from rotting fruit. According to the Ministry of Environment and Forestry (KLHK), the incidence of waste produced in Indonesia is 23 million tons / year and 22.3% comes from traditional marketwaste. Fruit waste can be utilized into Organic Fertilizer Cwater (POC) in order to have a selling value and not pollute the environment. In thepreviousstudy, the additional material used was cassava and only measured the nutrient levels of Liquid Organic Fertilizer formed without application to the plant,so that in penelitian ini wasdone the addition of cassava peel in the manufacture of liquid organic fertilizers and its effectonthe growth of curly red chili plants. The method used is fermentation inside the reactor equipped with a temperature stabilizedbottle. Processing is carried out anaerobically for 2 weeks with a variety of additional materials in one of the reactors, namely the addition of cassava peel. The parameters to be observed are pH levels, viscosity, plant height and number of leaves. Based on the results of measurements of pH levels before fermentation and after fermentation, the pH of liquid organic fertilizers with the addition of cassava peel from 5 to 3 and pH of Liquid Organic Fertilizer without the addition of cassava peel from 6 to 4. The results of measurement of the viscosity level of Liquid Organic Fertilizer without cassava peel 9,544x10-4 N. s/m2 while liquid organic fertilizer without cassava peel 7,858x10-4 N. s/m^2. This means that liquid organic fertilizer without cassava peel is more easily absorbed by the soil because the viscosity value is lower and close to the water viscosity value of7,768x10-4 N. s/m^2. The application of Liquid Organic Fertilizer to the curly red chili plant canget a maximum result of its effect by Liquid Organic Fertilizer without the addition of cassava peel.
