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.

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:
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:
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:
Despite many studies being conducted on mobile learning acceptance, few investigate mobile-based assessment acceptance. The objectives of this research are to provide valuable insights into current research on mobile-based assessment literature, and to identify the main gaps in the mobile-based assessment acceptance literature. Therefore, the present study systematically reviews 48 previous studies and eight articles related to mobile-based assessment acceptance to provide a comprehensive analysis of the articles published from 2009 to 2019. Findings indicate that majority of mobile-based assessment studies focused on evaluating the effectiveness and performance of mobile-based assessment system and conducted at the secondary school level. In addition, this study identified several gaps. Further research is needed to study the acceptance problem of a mobile-based assessment system. More investigation is required to predict which external factors that can enhance the acceptance and use of mobile-based assessment among students. The findings of this review study provide a valuable reference for researchers about the current trend of mobile-based assessment research as well as the research gaps that should be covered in future studies.

Abstract:
The study described the extent of knowledge in ICT skills of 180 teachers as a basis for a training plan in a selected schools division in Region 3. A descriptive survey method was utilized having a weighted mean and standard deviation to treat the data collected. It was concluded that the teachers displayed a proficient extent of knowledge in basic ICT skills. However, some of the skills enumerated have a low mean and were close to the adjacent group scale of the lower level of knowledge. Furthermore, they showed limited knowledge in some advanced computer applications which are necessary for the construction of instructional materials. The self-assessment revealed that they are knowledgeable in ICT skills, but they do not know how to use it in complex applications. The skills for development based on the training needs assessment reiterated a combination of skills which further clarified that not all skills under a certain application are known. It is then recommended that training needs assessment should always be conducted by school administrators to gather data on the actual needs of the teachers as a basis in planning a thorough training matrix to ensure that the development and training provided are based on the needs of the teachers.

Abstract:
The case of malnutrition affecting many toddlers of Banjarmasin in isolated areas, remote areas, and remote villages. It is caused by the resultant of economic problems, facilities, infrastructures, and the lack of medical personnel. One of the ways undertaken by the government to overcome this problem is to carry out Posyandu activities. The posyandu program is organized to improve and monitor the nutrition of children under five. However, the reporting of posyandu data by each puskesmas is sometimes delayed because of the large amount of bureaucracy that must be passed to get to the center. Therefore a system feeder application is needed to monitor and mapping on the number of toddlers with potential malnutrition in the city of Banjarmasin.
