Abstract

X is a company that works in the field of oil palm plantations and has a palm oil production capacity of 60 tons per hour. The products of palm oil that have been produced are Crude Palm Oil (CPO) and Palm Kernel Oil (PKO). The various kinds of waste produced by the company as a result of the palm oil industry process are liquid waste, palm kernels, fiber and seed shells. Liquid waste is used as organic fertilizer for oil palm plantations which will be sent through a liquid waste pump machine. Damage that occurs to the liquid waste pump machine will inhibit the delivery of liquid waste to the plantation, thus affecting the yield of palm oil from the plantation itself. This study describes the application of repair and preventive maintenance policies for liquid waste pump machines by looking at the frequency of damage to the liquid waste pump engine and predicting the delivery of liquid waste to the pump engine for the next period as well as providing solutions for handling damage that occurs in the liquid waste pump engine. From the results of calculations on data processing, the results of how to control the causes of damage that occur in the liquid waste pump machine can be overcome by using the Preventive Maintenance Method within a period of 1 month and maintenance of every component in the liquid waste pump machine within 1 cycle, namely 357.27 hours with a repair time of 5.82 hours. Controlling other causes of damage is to add a filter to the liquid waste pool so that stones, leaves and liquid waste husks do not hinder the suction pipe of the liquid waste pump machine.

Abstract

We have studied and compared the effects of full and partial halo geomagnetic storms on the high latitude ionosphere. The study used the total electron content (TEC) data obtained from the global positioning system (GPS) to examine the level of response of high latitude ionosphere around Ny Alesund, Norway to full and partial halo geomagnetic storms of June 23rd 2015 and January 1st 2016 respectively. This study was carried out using a dual frequency ground based GNSS observations at high latitude (NYAL: 78.56oN, 11.52oE) ionospheric station in Norway. The vertical TEC (VTEC) was extracted from Receiver Independent Exchange (RINEX) formatted GPS-TEC data using the GOPI Software developed by Seemala Gopi. The GOPI software is a GNSS-TEC analysis program which uses ephemeris data and differential code biases (DCBs) in estimating slant TEC (STEC) prior to its conversion to VTEC. From the results, the responses of the high latitude before the storm days were more positive than on the storm days. Also the overall response of the high latitude to the full halo geomagnetic storm was more positive with more impact than that of the partial halo geomagnetic storm.

Abstract

The Barito River as the largest and longest river in South Kalimantan has been convicted as the most polluted river on an international level. Where one of the most commonly found compounds is the heavy metal lead (Pb) with a high enough levels that alternatives are needed to reduce the levels of the metal. One way to reduce the levels of such heavy metals is to use activated carbon hyacinth. So the activated carbon from hyacinth is made in accordance with SII No.0258-79 and knows the effect of variations in the administration of activated carbon hyacinth at a time of 15 minutes, 30 minutes and 45 minutes in lowering the levels of lead heavy metals (Pb). The research method used to determine the effect of variations in the administration of activated carbon hyacinth is by quantitative testing using the Atomic Absorption Spectrophotometry tool. The results showed that activated carbon hyacinth has met SII No.0258-79 with a randemen test result of 15%, water content of 3%, and absorption of iodine of 241.16 mg / gram. Significant value produced 0.742 with regression value (r) 0.999 and resulted in decreased lead metal levels in the variation of 15 minutes activated carbon administration of -0.030 mg / l with an absorption of 120%, 30 minutes of 0.073 mg / l with an absorption of 48% and 45 minutes of -0.097 mg / l with an absorption of 167%. Hyacinth activated carbon can be used to lower the levels of lead heavy metals (Pb) with a maximum contact time of 45 minutes by 167%.

Abstract

One form of information technology management for UMKM in order to expand business networks, marketing and carrying out business processes is the use of the Cobit 5 framework. The benefits and maturity level of IT management are benchmarks for the direction of development and utilization strategies for UMKM. The purpose of this study was to assess the position of Kasasiur Banjar SMEs regarding implementation and targets to be achieved in the future. The result of the assessment is the maturity level of the current IT management position (existing). Furthermore, maturity targets will be determined for each selected IT process to be used as guidelines for the Kasasiur Banjar UMKM group in IT utilization. Maturity level assessment uses the domains EDM3, EDM4, APO7, DSS3, DSS6, and MEA1 with the calculation model referring to ISO/IEC 15504. Assessment results Maturity level related to IT development strategy is at level 1 (1.21), which is Performed. This means that Kasasiur Banjar SMEs have a concern for good IT management and processes have been implemented and achieved goals. The direction of governance development in UMKM Kasasiur Banjar is targeted to reach level 5, namely Optimizing.

Abstract

Formulations of Herbal medicine are continuously being developed to improve health and treatment through natural ingredients obtained from the surrounding environment with scientific evidence. Common problems in herbal medicine are bioavailability, solubility, absorption of active substances and low stability. Recently, it has become a development trend to enter the realm of nanoparticle technology to its application in herbal drug formulations. Nanoparticle technology is a technology of drug particles are made on the nanoscale (10 nm-1000 nm). Many studies have been carried out on the development and application of nanoparticle-based delivery technology containing natural ingredients, from these results nanoparticle-based delivery technology has succeeded in delivering these natural materials through certain mechanisms in increasing the activity and bioavailability of herbal medicinal compounds. Particles at the nanoparticle scale have distinctive physical properties compared to particles at a larger size, especially in increasing the amount and purpose of delivering drug compounds. Another advantage of nanoparticle technology is the potential to be combined with other technologies, thus opening up opportunities to produce more perfect and targeted delivery systems. Examples of nanotechnologies that can be used are polymer nanoparticles, solid lipid particles, magnetic nanoparticles, and others. The manufacture of preparations based on nanoparticle technology is an alternative in the manufacture of herbal medicines and it is hoped that the bioavailability and therapy produced in the body will be better.
