Abstract

Organic fertilizers are environmentally friendly fertilizers made from natural ingredients so that the use of organic fertilizers does not pollute the environment and damage the soil. Oil Palm Empty Bunches (TKKS) is one of the wastes from palm oil processing which can be used as solid organic fertilizer. At present, the potential for utilizing TKKS as a raw material for making organic fertilizers is very large. This study aims to determine the technique of making organic fertilizers with basic ingredients of TKKS fi bers and earthworms (Lumbricus rubellus), and find out the nutrient content contained in them. This research was carried out by an experimental method on an organic fertilizer maker or unit. Based on the results of the study, solid organic fertilizers can be made with basic TKKS ingredients and the decomposition process using earthworms (Lumbricus rubellus). In 100 grams of solid organic fertilizer produced containing nutrients namely Na dd (cmol/kg) (0.44), Total N (0.24%), P Total (mg P2O5/100g) (133.54%), Total K (mg K2O/100 g) (147.92), Mg (0.01), Za (55.62) and Fe (44.117).

Abstract

This research is a real-time measurement system design by utilizing an ultrasonic sensor that is connected to the Arduino Uno microcontroller. Testing is done by testing the performance of claybath miniature, which will separate the kernel and shell material using a suspension of calcium carbonate. Data obtained from sensor that have been previously calibrated will be analyzed, ie by comparing reference data obtained from measurement manually using a hydrometer. The result showed that the ultrasonic sensor and Arduino Uno microcontroller can be used as a specific gravity reading sensor that works in real time. The accuracy of sensor reading is 99.4% in the measurement range 1,010 - 1,120 kg/liter, with an average difference of 0.006 kg/liter.

Abstract

Palm oil shell biomass has the potential to be converted into bio oil, based on its content such as lignocellulose content (lignin, hemicellulose and cellulose). To get this bio oil product can be done through the pyrolysis process, using a temperature of 150°C with a sampling time span of 20 minutes, 30 minutes and 40 minutes. The experimental result showed that the characteristic of bio oil in a 20 minutes sample had better quality result, ie with an average density value of 1.0286 (gr/ml), pH 3.03, and blackish brown color.

Abstract

The purpose of this research is to determine the level of significance of the influence of the presence of students in attending lectures on the test result. The research method used is descriptive quantitative by calculating the correlation between the two variables. Whereas data processing is quantitative by using statistical analysis. The sample used was the Standard Operating Procedure Logistics course, which was attended by 117 students in Logistics Management Department class of 2017 and 2018. The result showed that the presence of students in attending lectures (absenteeism) had a strong influence on test score (positive correlation). While the value of exam result is influenced by attendance by 33.28% and 66.72% is influenced by other factors.

Abstract

The performance of palm oil mill (POM) can be seen from several indicators, such as oil extraction rate (OER), kernel extraction rate (KER), throughput, oil losses and kernel losses. The achievement of these indicators may be related to the processing time of the POM. The purpose of this research was to determine the relationship between the processing time on the performance of POM, especially OER, KER, throughput, oil losses and kernel losses. The method used is correlation analysis, which is a statistical analysis to see the relationship between two variables, ie the processing time variable with each of these performance variables. The result of the analysis show that the processing time have a weak and negative relationship to OER, KER and oil losses, weak and positive to kernel losses, and strong and negative to throughput. The increase in processing time had a bad impact on the four indicators, ie OER, KER, throughput and kernel losses, but had a good impact on oil losses.

Abstract

This research aims to determine the percentage of waste carried using a fruit basket and jerigen, and get a comparison of work performance using jerigen and brondolan basket containers. The study was conducted at PT Wahana Plantation and Product located in Sona Village, Gandis District, Sintang Regency, West Kalimantan on March 29 to April 6 2019. This research used the direct application method and field observations. The results showed that the percentage of waste in fruit basket containers was smaller (4.8%) than jerigen (6.3%). Work performance obtained from the fruit basket container was higher (0.93 hk/ha) compared to jerigen (0.70 hk/ha).

Abstract

Turn over ratio (TOR) is the ratio between expenditure/usage/sales to inventory. The higher TOR means the faster inventory turnover, which also means that the utilization of investment is higher or more efficient. The lower TOR means that capital turnover or investment is slower and less efficient. The purpose of this research was to determine the performance of the inventory of production machinery spare parts in the warehouse through the inventory turnover ratio. This research uses quantitative analysis. There are 435 types of spare parts in the warehouse, but only 63 types were used during the observation period. The result showed that the performance of spare parts inventory had various inventory turn over ratio, which ranged from 0.01 – 48.00 times during the period January, 1st – June, 15th 2018 or ranged 0.03 – 100.70 cycle per year. While the storage time of spare parts inventory ranged 2.98 – 11.368.50 days.

Abstract

Systemic and contact herbicides have a difference in the time it takes to kill weeds. The objectives of this experiment were to know time of change and physic condition of Axonopus compressus after systemic and contact herbicides application. This research conducted at Teaching Farm 2 Politeknik Citra Widya Edukasi on November – December 2019. This research was arranged in a non factorial completely random design with two treatments, A1 (Systemic herbicide) and A2 (Contact herbicide). Systemic herbicide using Glifosat 1%, and contact using Paraquat dichlorida 1%. Each of treatments repeated three times, so that there were 6 experimental unit. The data was analysis of variance and LSD Test. The result of this research are application of systemic and contact herbicides siginifficanty affected to time of change and physic condition of Axonopus compressus. The fastest change time and highest physical condition score is in contact herbicide treatment, and significantly different with systemic herbicide. Systemic herbicides inhibit the growth of weeds by entering the tissues, whereas contact only affects the affected part.

Abstract

Sugar cane plantations are often located on uplands with low irrigation water sources and get water sources from rainfall. Mycorrhiza increased water absorption and effective in dry land. This research aims to determine the best watering frequency and dose of mycorrhizae for sugarcane single bud seedlings. The research was conducted at Research Garden of KUD Ngajum located in Wonosari, Malang, East Java. The research was conducted in May to August 2013. The research method was used a Completely Randomized Design (CRD) consisting of two factors. The first factor was mycorrhizal dose consisting of 4 levels: without mycorrhiza (M0), 10 g /plant (M1), 30 g/plant (M2), 50 g/plant (M3). The second factor was the frequency of watering consists of 4 levels: once a day (F1), once every two days (F2), once every three days (F3), four days (F4). Application of mycorrhizae of 10 grams, 30 grams and 50 grams had the same effect on all parameters of sugarcane seedling growth except the number of tillers, leaf area and percentage of mycorrhizal infection. Frequency of watering every 2 days gives good results on the parameters of plant dry weight. The combination of 50 grams of mycorrhizal treatment with watering frequency once every 2 days gives a good effect on leaf area while the combination of treatment of 10 grams of mycorrhizae and watering once every 4 days and my dose of 30 grams of mycorrhizae with frequency of watering once every 3 days gives a good effect on the percentage of mycorrhizal infections.
