THE INFLUENCE OF WORKING UNDER-PRESSURE TO GAIN THE COMPANY PROFIT AT PRIVATE UNIVERSITIES IN MEDAN, INDONESIA

Safrida

Economy Faculty, Islamic University of North Sumatra (UISU), Medan, Indonesia

ABSTRACT: In work, the working environment directly affects the work attitude and determine employee performance. The pleasant working environment makes a positive employee attitude and gives the impetus to work more diligently and better. Conversely, if the environment situation is not fun they tend to leave the environment. stress is a negative emotional experience that is experienced by individuals when facing the greater demands of his skill. The negative emotional experiences of individuals can be defined as the perceived negative affective state. Negative affective include: feelings of sadness, disappointment, anxiety, anger and depression. the educational staffs in most of universities in Medan City show that there are still many educational staff who refuse to change the culture within the organization, especially regarding the development of information technology as an opportunity for the educational staff to learn the improvement. Work stress affects the employees. This means that the higher of the work stress level is, the higher the employee performance is.

A Personal Working Attitude at Private Universities in Medan, North Sumatra, Indonesia

Safrida

Economy Faculty, Islamic University of North Sumatra (UISU), Medan, Indonesia

Abstract: It is good to work very hard…but it is not good enough! If that sweat and toil is not giving you the results you need then it has very little value. Try this definition of good performance…Doing (A) – the right activities. Getting (R) – the right results. Using (i) the right intentions, purpose, motivation etc.This is helpful because it is all about doing the right things and having the right approach. Lucky people can get good results…but not perform well. People can be unlucky (a product they are selling gets recalled) but demonstrate outstanding performance. You cannot simply judge people’s performance on sales results, production targets, click rates or staff turnover – judge performance on what they do and why they do it…in addition to the results they get. A personal working attitude does not affect the performance of the employees. This is because the educational staffs in most of universities in Medan City show that there are still many educational staff who refuse to change the culture within the organization.

ABSTRACT

Soybeans are one of the agricultural commodities that are economically strategic sectors in Indonesia. The main limiting factor for soybean production is the availability of quality seeds because soybean seeds rapidly deterioration in storage. This study aimed to determine the effect of packaging type and storage period on the physiological aspects of soybean seed viability. The study was conducted at the Balai Benih Induk Laboratory, Medan, North Sumatra, Indonesia from January to September. The study used factorial Randomized Completely Design with 3 replications. The first factor is the packaging type (P) consisting of 4 levels: container (P1); plastic bags (P2), pots (P3), wooden box (P4). The second factor is the save period (S) consists of 3 levels: 2 months (S1), 4 months (S2), 6 months (S3). Variables observed were seed water content, germination, germination rate index, anaphase index, and chromosome aberration. The results showed that soybean seeds stored in container were able to maintain the quality of their seeds for 6 months in the storage period based on a decrease in water content, germination, and anaphase index. Soybean seeds stored in container can reduce the rate of deterioration of seed viability based on the germination rate index. Although the germination of soybean seeds stored in container for 6 months is still above 90%, they have experienced chromosome aberration.

KEYWORDS: Soybean seed, packaging, storage period, water content, seed viability.

ABSTRACT

Tapping and stimulant applications are an attempt to increase latex yield. A combination of stimulants with low intensity tapping systems was expected to reduce tapping costs. In addition, it was necessary to regulate the stimulant application frequency based on type and potential clone production. The objective was to determine the effect on physiological parameters and latex yield of Hevea brasiliensis (Willd. ex A. Juss.) Müll. Arg. clone PB 260 for different tapping and stimulant application frequencies. The study design was split block in randomized complete block plots with three replicates and two factors. The main plot was the tapping system consisting of four levels: quarter-spiral downward tapping (S/4 d3), quarter-spiral upward tapping (S/4U d3), half-spiral downward tapping (S/2 d3), and half-spiral upward tapping (S/2U d3). The subplots were four stimulant application frequencies consisting of ethephon 2.5% applied once every 15 d (ET 15d) and gas stimulant (equal to ± 100% ethylene) applied once every 9 d (ETG 9d), once every 18 d (ETG 18d), and once every 27 d (ETG 27d). The highest sucrose levels (3.62 mM) were obtained in S/2 d3 and ET/15d combination. The highest inorganic P content (27.68 mM) was in S/2 d3 and ETG/18d. The highest yield (2418.53 kg ha-1 yr-1) was in S/4d3 and ETG/18d. The tapping system S/4d3 and ETG/18d combination was able to increase production by 102.26% compared with the conventional tapping system (S/2 d3 and ET/15d). After the 1-yr trial, all treatments showed 0.47 to 0.54 mM thiol content, which indicated that plants did not experience over-exploitation stress.

Key words: Ethephon, ethylene gas, inorganic phosphorus, rubber tree, sucrose, thiol.

Abstract

Sucrose levels, inorganic phosphate and thiol are physiological characteristics of rubber plants that are closely related to the ability of plants to produce latex. This study aimed to determine the correlation between physiological characters and latex production of GT1 clone latex, and the timing of proper stimulant application without disturbing the health of rubber plants. The research was carried out in smallholder rubber plantations. The research was carried out in Harapan village, Sei Lapang, Langkat District, North Sumatra Province and Physiology Laboratory of Sungei Putih Research Institute. The clones tested in this study were GT1 clones at the age of 20 years. This study used the method of statistical analysis Correlation and Regression Test. Based on statistical analysis. The results of correlation analysis show that sucrose levels were negatively correlated with latex production, where high sucrose levels of low latex production were the opposite. In June the production of high latex was influenced by physiology of latex as much as 57.25%. This condition was appropriate time for stimulant application on GT 1 clones.

Abstract

The enzyme content of banana xylase contains chemical elements such as magnesium, sodium, phosphorus, sulfur so that banana skin has good potential to be used as organic fertilizer. The purpose of this study was to determine the effect of giving banana skin liquid organic fertilizer and chicken manure, as well as knowing the most optimal dosage against the growth and production of cucumber. This study used a Randomized Block Design (RBD) with two factors, namely the dose of liquid organic fertilizer and manure. The dose of banana organic fertilizer used is (0 mL/plant), P1 (20 mL/plant), P2 (40 mL/plant), and P3 (60 mL/plant). The doses of chicken manure used are A0 (0 kg/plot), A1 (2 kg/plot), A2 (4 kg/plot) and A3 (6 kg/plot). The results showed that banana peel liquid organic fertilizer had an effect on the number of productive branches, giving chicken manure affected the number of productive branches but did not fall on the weight of the fruit per sample and the weight of the fruit per plot. The most optimal dose for banana skin organic liquid fertilizer is P2 (40 mL/plant) and the most optimal dose for chicken manure is A3 (6 kg/plot).

ABSTRACT

The land in Berastagi has a high erosion potential caused the high intensity of rainfall, steep slopes, and the cropping pattern is not good. Long-lasting erosion has lowered soil fertility and even reduced or eliminated soil tillage. This study aimed to obtain the appropriate intercropping pattern in the Berastagi dry land of Karo Regency, Indonesia. This study conducted a non-factorial randomized block design method with 5 replications. The treatment is in the form of farmers planting patterns and improved cropping patterns, namely P1, P2, P3, P4, and P5. The results showed that improved cropping patterns yielded higher rice equivalent yields compared to farmers’ cropping patterns. Improved cropping patterns of P4, P2, and P3 are economically feasible in the Berastagi Karo dry land because they have a marginal B/C ratio above two, while the farmers’ cropping pattern, namely intercropping of upland rice/cassava has the lowest B/C ratio of 1.72.

ABSTRACT

Nutrient recycling and mineral balance are important factors affecting nutrient budgets in oil palm (Elaeis guineensis Jacq.) plantations. The nutrient budget includes processes such as plant uptake, removal by harvesting, accumulation or storage in the standing plant, and recycling through decomposition of cover crop Asystasia gangetica (L.) T. Anderson can be utilized as cover crops in mature oil palm plantations with appropriate management. This study aimed to examine the growth of A. gangetica in 17 yr old oil palm plantations with different populations, understanding the contribution of A. gangetica to improve available nutrient in the plantation on the nutrient balance, and to study its role as cover crop in the mature oil palm plantation. The experiment was conducted in an experiment field of 17 yr old of mature oil palm at Bogor, Indonesia. Results showed that A. gangetica can be used as cover crops in mature oil palm plantations because it meets several conditions such as rapidly covering the land (11 wk after planting), and able to increase the available N, P, K as much as 18.49%, 9.20%, 38.36%, respectively, based on the nutrient balance with the optimum population is 1 000 000 plants ha-1.

Key words: Cover crop, Elaeis guineensis, nutrient availability of N, P, K, nutrient balance.

ABSTRACT

This study aimed to determine the growth response and okra plant results on various colors of plastic mulch and goat manure. The study was conducted in Namorambe, Deli Serdang District from February 2017 until June 2017. The study used Split Plot Design in a randomized complete block design with three replications and two factors. The main plot is a plastic mulch color (W) consisting of three levels, namely: silver (W1), black (W2), and transparent (W3). The subplot is a dosage of goat manure (K) consisting of four levels, namely: 0 t/Ha (K0), 10 t /Ha (K1), 15 t/Ha (K2), and 20 t/Ha (K3). The results showed the use of plastic mulch colors and goat manure dose did not affect the growth of okra, but affects okra yield. The pattern of the relationship between the growth of okra and the okra yields a quadratic line equation. The yield of okra is more influenced by the height of plant compared with the number of leaves based on the value of its determinant coefficient (R2).

KEYWORDS: Growth response, okra plant, coefficient.
