Hubungan Self-Efficacy dan Social Loafing Tendency Pada Mahasiswa
Authors: Purba Regina A S , Eliana Rika
Published: January 2019

Pendekatan pembelajaran yang berbasis tugas atau kerja kelompok bukan hal yang asing bagi para mahasiwa. Namun tugas yang diberikan dengan cara berkelompok memungkinkan terjadinya pemalasan sosial (social loafing), dimana individu mengurangi usahanya ketika ia bekerja dalam kelompok, dibandingkan ketika ia bekerja secara individual. Artinya pemberian tugas secara berkelompok bisa membuat individu yang seharusnya bertanggung jawab secara pribadi apabila tidak terkontrol dapat memungkinkan terjadinya pemalasan sosial yang justru menurunkan efektivitas pembelajaran itu sendiri. Untuk itu penelitian ini dilakukan bertujuan untuk mengetahui apakah ada hubungan self- efficacy (keyakinan seseorang tentang kemampuan individu untuk melakukan satu tugas) dengan social loafing tendency. Penelitian ini dilaksanakan terhadap 300 mahasiwa pertanian dari dua universitas di kota Medan yaitu 150 mahasiswa dari Universitas Sumatera Utara dan 150 mahasiswa dari Universitas Methodis Indonesia. Proses pembelajaran melalui metode pembelajaran yang berbasis tugas kelompok cukup dominan menonjol khususnya di fakultas Pertanian di kedua universitas tersebut. Pengukuran menggunakan alat ukur Social Loafing Tendency berdasarkan teori Latane, sedangkan Self Efficacy berdasarkan Bandura. Hasil penelitian menunjukkan bahwa ada hubungan negative antara kedua variable tersebut. Semakin tinggi self-efficacy seseorang maka semakin rendah social loafing tendency.

 

A task-based or group work learning approach is not a new thing for the college students. But the task given in groups allows social loafing, where the individual reduces his effort when he works in groups, compared to when he works individually. This means that giving assignments in groups can make individuals who should be personally responsible if they are not controlled can allow social idling which actually reduces the effectiveness of learning itself. For this reason, the study was conducted aimed at finding out whether there is a relationship between self-efficacy (a person's belief in an individual's ability to do a task) and social loafing tendency. The study was conducted on 300 agricultural students from two universities in Medan, with 150 students from the University of Sumatera Utara and 150 students from the Methodist University of Indonesia. The learning process through group-based learning methods was quite dominant, especially in the Faculty of Agriculture in both universities. The measurements done by using a Social Loafing Tendency based on Latane theory and Self Efficacy which based on Bandura. The results showed that there was a negative relationship between the two variables. The higher a person's self-efficacy, the lower the social loafing tendency.

Published: January 2019

Kabupaten Karo merupakan sentra produksi tanaman hortikultura di Sumatera Utara dengan jumlah kelompok tani yang mencapai 3.003 kelompok. Namun hanya 44 kelompok yang berada pada kelas “Lanjutan” sementara sisanya berada di kelas “Pemula”. Untuk menganalisis kondisi tersebut, dilakukan penelitian di Kecamatan Barusjahe, sebab daerah tersebut memiliki perkembangan kelompok tani yang paling baik (Bapeluh Kabupaten Karo, 2014). Data diperoleh dari penyuluh dan kelompok tani yang ditentukan dengan metode sensus dan purposive sampling. Selanjutnya data diolah dengan menggunakan metode skoring terhadap 49 indikator untuk menentukan peran penyuluh dan 20 pernyataan positif dan negatif untuk menentukan sikap anggota kelompok tani terhadap peran penyuluh. Hasil penelitian menunjukkan bahwa total skor peran penyuluh adalah sebesar 114,53 dan termasuk dalam kategori “sedang”, dan 72,22% anggota kelompok tani bersikap positif terhadap peran penyuluh pertanian tersebut. Kondisi tersebut merupakan peluang untuk pengembangan kelompok tani di Kecamatan Barusjahe, namun perlu perbaikan dalam beberapa hambatan seperti kesadaran pengurus dan anggota kelompok, partisipasi anggota kelompok, perencanaan dan pelaksanaan program yang memiliki komoditi berbeda dan areal lahan yang tidak pada satu hamparan, jumlah tenaga penyuluh, kelengkapan dan kesesuaian sarana dan prasarana yang dimiliki. Diharapkan dengan perbaikan hambatan tersebut kelompok tani di Kecamatan Barusjahe dapat mencapai tingkat kelas yang lebih tinggi.

 

Karo Regency is a center for horticulture production in North Sumatra with a total of 3,003 farmer groups. However, only 44 groups were in the "Continuation" class while the rest were in the "Beginner" class. To analyze these conditions, research was conducted in Barusjahe District, because the area had the best development of farmer groups (Bapeluh Karo District, 2014). Data obtained from extension agents and farmer groups were determined by the census method and purposive sampling. Furthermore, the data were processed using the scoring method on 49 indicators to determine the role of extension agents and 20 positive and negative statements to determine the attitude of members of farmer groups to the role of extension agents. The results showed that the total score of the instructor's role was 114.53 and included in the category of "midwife", and 72.22% of members of the farmer group were positive towards the role of the agriculture extension agents. This condition was an opportunity for the development of farmer groups in Barusjahe Subdistrict, but still needed to be improved in several obstacles such as awareness of administrators and group members, group member participation, planning and implementation of programs that had different commodities and land areas that were not in one overlay and suitability of facilities and infrastructure owned. It was expected that by improving these barriers, farmer groups in Barusjahe Sub-district could reach a higher class level.

Authors: Nurrahmi Febri
Published: January 2019

The signing of Memorandum of Understanding (MoU) between the Government of Indonesia and The Free Aceh Movement (GAM) in 2005 in Helsinki officially ended the armed separatist movement in Aceh. The long history of separatist movement in the region had created the question of identity between Acehnese and Indonesian identities among Acehnese. This study investigated the construction of Acehnese identity in relation to Indonesian identity in Serambi Indonesia, the most prominent local media, after the signing of the Helsinki peace accord. This study used a textual analysis to examine the construction of Acehnese identity through the use of symbolic language. The sample of 88 articles collected from July 2012 to May 2013 were analyzed based on five coding categories; themes, framing perspectives, labels to describe Aceh, labels to describe Indonesia, and depiction of Aceh-Indonesia relations. Findings revealed that Serambi Indonesia had managed to negotiate the tension between Acehnese and Indonesian identities. The newspaper overtly legitimated Aceh as an Indonesian region while maintaining the specialty of Aceh in comparison to other provinces of Indonesia. These findings suggested that the local media played a significant role in identity reconciliation during the reconciliation process in the post-conflict area

The process of economic transformation has become a necessity to make changes towards industrialized countries. The transformation is conducted so that the economy is able to compete in the global market. The purpose of writing this paper was to convey the trees of thoughts and ideas of the importance of economic integration in addressing society's income distribution inequality in the ASEAN countries. According to the estimated Gini index, ASEAN countries actually fell into the category of economic inequality. This means that the inequality happened too extreme and there was a positive movement towards equitable distribution of economic opportunities for the population. Therefore an inclusive development-oriented growth inclusive long-term was needed. Inclusive development aimed at reducing the number of poor population and unemployment in order to be able to take advantage of the market to base prosper. Inclusive development required improvement in the field of human resources, government bureaucracy, institutional economics, infrastructure improvements, strict law enforcement, satisfy basic needs certainty, and mastery of the science, technology, and political stability. This paper concluded that the economy of ASEAN countries had not yet fully managed so well that the inclusive development process should give priority to a strong and stable economy facing global competition. The difference in their respective interests was not yet guarantying the formation of the economic integration of the ASEAN countries that were less competitive. Therefore, there was a need for an agreement based on the principle of mutual needs, mutual raising, and mutual benefit. This paper also suggested ASEAN countries to fix the detailing things in order that investments grew rapidly in their respective countries. Investment and exports of industrial products were the two factors that elementary in order for resilience and economic integration could be formed quickly and productively

Kebutuhan memberi payung hukum bagi pekerja non formal seperti Pekerja Rumahan (PR) masih diperdebatkan, bahkan oleh pemerintah daerah. Ada anggapan mengatur perlindungan PR akan mendistorsi iklim investasi, sehingga harus dilakukan evaluasi Raperda ke Kementerian Dalam Negeri. Aliansi Pekerja Rumahan bersama Bitra dan Akademisi, dan Dinas Tenaga Kerja telah beberapa kali melakukan pertemuan guna menyamakan persepsi tentang konten dari Raperda dimaksud. Tulisan ini disusun berdasarkan data yang diperoleh dari lapangan yang penulis ikuti dalam proses pembahasan Raperda di DPRD Provinsi Sumatera Utara tepatnya di Komisi E. Rekaman atas pertemuan dan kegiatan dimaksud direkam kemudian dibuat dalam bentuk transkrip. Analisis dilakukan berdasarkan hasil pembicaraan dalam pertemuan-pertemuan resmi tersebut. Peneliti berkesimpulan bahwa tidak adanya respon yang besar dari Komisi E DPRD untuk mensegerakan pembahasan Raperda dalam Badan Legislasi DPRD karena rendahnya pemahaman anggota dewan dan kekuatiran yang berlebihan akan dampak dari formalisasi pekerja rumahan.

The necessity to provide protection for non-formal workers such as homeworkers is still controverted even by the local government. There is an assumption that the management of the protection of homeworkers will distort investment climate so the Local Government Regulations Plan evaluation must be carried out to the Ministry of Internal Affairs. The Homeworkers Alliance with Indonesian Rural Skill Development (Bitra) and Academics and Labor Offices have been holding many conferences in order to equalize the perceptions about the Local Government Regulations Plan. This paper was compiled based on the data obtained by the writer during Local Government Regulation Plan discussion in Regional People’s Representative Assembly (DPRD) in E commission. The conference and the activity were recorded and a transcript was created from the recording. The analysis was conducted based on the discussion result from the conferences. The writer concluded there was no big response from E commission of Regional People’s Representative Assembly (DPRD) due to the low understanding of the assembly member and the exaggerating concern that would give impact to Homeworkers formalization

Perbandingan Keakuratan Dari Model Tabel Distribusi Frekuensi Berkelompok Antara Metode Sturges Dan Metode Scott
Authors: Sari Wanda Maya , Darnius Open , Sembiring Pasukat
Published: January 2019

Distribusi Frekuensi berkelompok adalah penyusunan urutan data tunggal ke dalam tabel kelas-kelas interval, untuk kemudian ditentukan frekuensinya. Penyusunan ini berguna untuk menyelidiki kumpulan data sehingga dapat membawa informasi dengan cara yang pintas. Metode Sturges adalah aturan yang paling dikenal untuk menentukan jumlah kelas interval dalam distribusi frekuensi, namun terdapat kelemahan di dalamnya sehingga pada penelitian ini dilakukan analisis perbandingan keakuratan model tabulasi antara Metode Sturges dengan Metode Scott yang merupakan aturan untuk menentukan panjang kelas dalam distribusi frekuensi. Perbandingan dilihat dari hasil perhitungan selisih ukuran pemusatan, ukuran lokasi, serta dispersiantara kedua model terhadap ukuran dari data simulasinya (data aktual), kemudian dianalisis perbandingannya melalui jenis distribusi data, yang dalam penelitian ini menggunakan data berdistribusi normal dan eksponensial. Hasil perbandingan keakuratan dari masing- masing tabel distribusi frekuensi dari data normal maupun data eksponensial, menunjukkan persentasi keakuratan dari tabel distribusi frekuensi dengan metode scott lebih tinggi dibandingkan dengan metode sturges, hal ini dikarenakan, pada tabel distribusi frekuensi dengan metode sturges, terdapat data yang tidak masuk ke dalam tabel distribusi frekuensi diakibatkan nilai panjang kelas interval tidak dapat mencakup pengelompokkan sampai data tertinggi.

Group Frequency Distribution is the arrangement of a single data sequence into a table of interval classes, for which frequency is then determined. This arrangement is useful for investigating data sets so that they can carry information in a shortcut way. The Sturges method is the best known rule for determining the number of interval classes in frequency distribution; however, there are weaknesses in it. In this study, a comparative analysis of the tabulation model between the Sturges Method and the Scott Method, which is a rule for determining class length in frequency distribution, was conducted. Comparison was seen from the calculation of the difference in concentration size, location size, and dispersion between the two models to the size of the simulation data (actual data). Then the comparison through the type of data distribution was analyzed, which this study used normal and exponential distribution data. The results of the comparison of the accuracy of each frequency distribution table from normal and exponential data showed that the percentage accuracy of the frequency distribution table with the Scott method was higher than the Sturges method. It occurred because in the frequency distribution table with the Sturges method, there were some data not included in the frequency distribution table. It was caused by the value of the interval class length that could not comprise the highest grouping of data.

Published: January 2019

Penelitian ini dilakukan untuk menganalisis perbandingan hasil kompresi dan dekompresi file audio*.mp3 dan *.wav. Kompresi dilakukan dengan mengurangi jumlah bit yang diperlukan untuk menyimpan atau mengirim file tersebut. Pada penelitian ini penulis menggunakan algoritma Huffman dan Run Length Encoding yang merupakan salah satu teknik kompresi yang bersifat lossless.Algoritma Huffman memiliki tiga tahapan untuk mengkompres data, yaitu pembentukan pohon, encoding dan decodingdan berkerja berdasarkan karakter per karakter. Sedangkan teknik run length ini bekerja berdasarkan sederetan karakter yang berurutan, yaitu hanya memindahkan pengulangan byte yang sama berturut-turut secara terus-menerus. Implementasi algoritma Huffman dan Run Length Encoding ini bertujuan untuk mengkompresi file audio *.mp3 dan *.wav sehingga ukuran file hasil kompresi lebih kecil dibandingkan file asli dimana parameter yang digunakan untuk mengukur kinerja algoritma ini adalah rasio kompresi, kompleksitas yang dihasilkan. Rasio kompresi file audio *.mp3 menggunakan Algoritma Huffman memiliki rata-rata 1.204% sedangkan RLE -94.44%, dan rasio kompresi file audio *.wav memiliki rata-rata 28.954 % sedangkan RLE -45.91%.

This research was conducted to analyze the comparison of the results of compression and decompression of *.mp3 and *.wav audio files. Compression was completed by reducing the number of bits needed to save or send the file. In this study, the researcher used the Huffman algorithm and Run Length Encoding which is one of the lossless compression techniques. The Huffman algorithm has three stages to compress data, namely tree formation, encoding and decoding which work based on characters per character. On the other hand, the run length technique works based on a sequence of sequential characters that only move the repetitions of the same byte in succession continuously. The implementation of the Huffman algorithm and Run Length Encoding aimed to compress audio files *.mp3 and *.wav so that the size of the compressed file was smaller than the original file where the parameter used to measure the performance of this algorithm was the compression ratio, and the resulting complexity.*.Mp3 audio file compression ratio using Huffman Algorithm had an average of 1.204% while RLE -94.44%, and compression ratio *.wav audio files had an average of 28.954% while RLE -45.91%.

Transportation problems are issues that often occur in everyday life. The problem of transportation with the amount of supply, number of demand, and transportation costs expressed by fuzzy numbers is referred to fuzzy transportation problems. In solving fuzzy transportation problems, fuzzy tables must be changed first to linear shapes so that they are easier to do. Robust ranking technique is a technique used to convert fuzzy transportation problems into linear transportation problems. To find the optimal solution, the Zero Suffix method was used to solve transportation problems with fuzzy variables. The Zero Suffix method started with the reduction of costs in the table row with the minimum cost in the row, then continued to reduce costs in the table column with the minimum cost in the column. Subsequently, it looked for the suffix value of each column, by selecting the largest suffix value. It proceeded to choose zero costs for the transportation tableau, chose the minimum of the demand and the inventory, and then continued to allocate it to the tableau. Searching for the suffix value continued until all rows and columns were saturated.

Antrian merupakan suatau keadaan menunggu giliran untuk dilayani dengan suatu model antrian tertentu. Pengaplikasian teori antrian pada penelitian ini bertujuan untuk meminimalisir banyaknya antrian yang ada dan agar tercapinya kinerja antrian yang optimal pada KFC Jln. Gajah Mada, Medan, Sumatera Utara. Hasil yang diperoleh dari permasalahan yang ada berupa jumlah optimal kasir yang beroperasi setiap harinya yang akan dibagikan atas kondisi ramai, sepi dan normal. Dalam Penelitian ini digunakan analisis sistem antrian jalur berganda (M/M/S). Proses perhitungan data menggunakan manual  dan  perangkat  lunak  ―Quantitative  for  windows‖  dengan  modul  Waiting  Lines.  Berdasarkan hasil penelitian diketahui bahwa kinerja sistem antrian yang ada kurang optimal karena mempunyai tingkat kegunaan fasilitas yang rendah dan tingkat kesibukan kasir masih rendah, seperti pada jam sepi kegunaan kasir hanya berkisar 17% dan pada jam ramai kegunaan kasir berkisar 42% serta pada jam normal kegunaan kasir hanya berkisar 38% sehingga untuk menyelesaikan permasalahn tersebut akan digunakan teori antrian dengan hasil akhir diperoleh bahwa banyak kasir yang beroperasi pada kondisi sepi adalah 2 kasir, kondisi ramai sebanyak 4 kasir dan pada kondidi normal dengan 3 kasir.

Queues are a state of waiting for their turn to be served with a particular queue model. The application of queuing theory in this study aimed to minimize the number of existing queues and to achieve optimal queuing performance at KFC Gajah Mada St., Medan, North Sumatra. The results obtained from the problem were in the form of the optimal number of cashiers operating each day which would be distributed on crowded, quiet and normal conditions. In this research, the analysis of multiple line queuing systems (M/M/S) was used. The process of calculating data employed manuals and software "Quantitative for Windows" with the Waiting Lines module. Based on the results of the study, it was known that the performance of the existing queuing system was not optimal because it had a low level of utility and cashier activity. In the quiet hours, the use of cashiers was only 17%. At peak hours the use of cashiers ranged from 42% and at normal hours about 38%. Therefore, to solve the problem, queuing theory was utilized. The final results obtained showed that there were 2 cashiers operating in quiet conditions, 4 in crowded conditions and 3 in normal conditions.

The quadratic assigment problem (QAP) has remainedone of the great challenges in combinatorial optimization. In this paper I propose two programs, the MATLAB program for solving QAP, and the MATLAB program for checking objective value, if we input an arbitrary permutation, matrix flow and matrix distance. The first program using combination methods that combines random point strategy, forward exchange strategy , and backward exchange strategy. I‘ve tried my program to solve Esc 16b, Esc 16c and Esc 16h from QAPLIB (A Quadratic Assignment Problem Library). In the 500th iteration optimal value reached and I‘ve found the other assignment for problem instances Esc 16b, Esc 16c, and Esc 16h.

Penelitian ini merupakan kajian masalah transshipment tidak seimbang menggunakan metode Least Cost - Stepping Stone. Metode Least Cost - MODI juga digunakan untuk membandingkan uji  optimalitas mana yang lebih baik dalam menyelesaikan masalah transshipment ini. Hasil dari penelitian menunjukkan bahwa metode Least Cost - SteppingStone dan metode Least Cost - MODI dapat menyelesaikan masalah transshipment tidak seimbang. Menurut uji perbandingan metode MODI lebih efisien dari pada metode Stepping Stone dalam menguji optimalitas suatu masalah transshipment karena metode MODI memerlukan lebih sedikit iterasi dibandingkan dengan metode Stepping Stone. Pada Metode MODI nilai indeks perbaikan dapat dicari tanpa harus mencari loop dari setiap sel kosong, yakni hanya membutuhkan satu loop yang didapat setelah menentukan sel dengan indeks perbaikan terbesar, sedangkan pada metode Stepping Stone nilai indeks perbaikan dicari dengan membuat loop untuk setiap sel kosong pada setiap iterasi. Selain itu Metode Least Cost menghasilkan biaya transportasi yang berbeda apabila posisi penempatan biaya diubah, sedangkan dengan metode Stepping Stone biaya transportasi akan tetap sama dan optimal apabila posisi penempatan biaya diubah.

 

This research is a study of unbalanced transshipment problems using the Least Cost - Stepping Stone method. The Least Cost - MODI method was also used to compare which optimality test was better in solving this transshipment problem. The results of the study showed that the Least Cost - Stepping Stone method and the Least Cost - MODI method could solve unbalanced transshipment problems. According to the comparison test, the MODI method was more efficient than the Stepping Stone method in testing the optimality of a transshipment problem because the MODI method required less iteration than the Stepping Stone method. In the MODI method, the repair index value could be searched without having to search for loops from each empty cell, which only requires one loop after determining the cell with the largest repair index. On the other hand, in the Stepping Stone method, the repair index value was searched by making a loop for each empty cell at each iteration. In addition, the Least Cost method produced different transportation costs if the placement position costs were changed. Meanwhile, the Stepping Stone method transportation costs would remain the same and optimal if the placement position costs were altered.
