Abstract

Law No. 14 of 2008 concerning Freedom of Public Information mandates that Public bodies must develop and develop information and documentation systems to manage Public Information properly and efficiently so that it can be easily accessed. This service aims to train village officials to use SiDeKa as one of the media that can encourage the emergence of four (4) types of novelty, namely: awareness, skills, habits and governance of Village Information Systems. These community service activities are carried out in three stages. The first stage is the location survey and distribution of ICT understanding questionnaires at the village / kelurahan level on Friday, 17 May 2019 at 09.00 - 11.00 WITA. The second phase is the SiDeKa workshop for Pantae village officials on Friday, June 28, 2019 from 08.00 - 13.00 WITA and the third stage is the distribution of feedback questionnaire on the implementation of SiDeKa activities that have been carried out on Friday, July 12, 2019 at 09.00 - 11.00 WITA. Constraints encountered include the lack of computer and internet facilities at the village office and there are still many village officials who do not yet have the knowledge in using information and communication technology devices. The benefit of this training activity is to increase the ability of Pantae village officials to manage coordinated village data with the help of a computer-based system so that they can provide accurate information and services that are more satisfying to the community.

Abstract

This study was conducted to estimate the company's optimal profit by considering the product supply chain in a company that receives orders from several distributors. If all orders cannot be fulfilled by the available production capacity, the company will offer a solution in allocating capacity to distributors by considering scheduling costs and other constraints. The main work in estimating the company's profit is modeling the scheduling costs and constraints in the capacity allocation problem in the company. That is, the company makes order scheduling to minimize costs to achieve maximum profit by applying the Karush-Kuhn-Tucker (KKT) method. Karush-Khun-Tucker can be used to find the optimal solution of the function formed from the allocation and scheduling problems whether linear or nonlinear. In the process, the KKT method basically involves the same steps as the Lagrange method to be able to calculate the critical point and find the optimum solution. It is suggested for further research to involve more varied variables with more interesting cases.

Abstract

Distribusi produk sepeda motor di PT. NSS dilakukan atas permintaan konsumen dari setiap wilayah di kabupaten TTU. Distribusi dijalankan secara tidak teratur atau acak, baik dalam distribusi waktu atau kuantitas. Aktifitas kegiatan mempengaruhi distribusi total biaya persediaan yang dikeluarkan perusahaan dalam pengadaan persediaan. Oleh karena itu perusahaan perlu memperhatikan aplikasi sistem distribusi kegiatan untuk mengoptimalkan distribusi jadwal pengiriman produk sepeda motor untuk menjaga waktu dan efisiensi biaya. Distribution Requirement Planning (DRP) adalah metode untuk menangani pengadaan persediaan dalam jaringan distribusi multi-level. Metode DRP berhubungan dengan ukuran lot pemesanan dan jumlah persediaan pengaman. Metode DRP mengurangi total biaya persediaan dan distribusi frekuensi kegiatan dengan menentukan distribusi penjadwalan yang efektif dengan pertimbangan bahwa distribusi dilakukan sesuai ukuran lot atau kelipatannya dan jumlah stok pengaman yang diperlukan. Hasil penelitian, sistem distribusi dan penjadwalan pengiriman produk sepeda motor pada PT. NSS Cabang Kefamenanu tahun 2016 didapatkan perencanaan distribusi dengan metode DRP lebih kecil bila dibandingkan dengan metode perusahaan. Total Cost (TC) dengan metode perusahaan adalah sebesar Rp. 233.391.197,00 dan Total Cost (TC) dengan metode DRP adalah sebesar Rp. 218.460.000,00 . Sehingga terjadi penurunan sebesar 6,4%. Kata kunci: Distribusi, Distribusi Multi Level, Perencanaan Kebutuhan Distribusi Requirement Planning (DRP), Ukuran Lot, Safety Stock.

Abstract

Assignment problem is one part of linear programming that can be found in real life. The Assignment problem includes m workers who have n tasks assuming n=m. The division of work is seriously handled by the company so that each employee gets an equal amount of work hours that are determined. This study aims to optimize employee assignments based on minimum operational costs and minimum job completion times using the Hungarian method. Optimization is a mathematical approach that deals with maximum and minimum problems. From the results of the study, after using the Hungarian method, the work completion time on the Kefamenanu Supermarket Metro was 9: 34: 20 (in hours, minutes, seconds). The total operational costs of work incurred by the company if calculated using the Hungarian method with MATLAB software, the results are Rp. 11,141. Furthermore, the order of minimization of employee assignments is obtained as follows: II, VII, I, IV, VI, V and III.

Abstract

The activity of filling in school data, student data, and student final grades in report card at elementary schools in the Insana Fafinesu District, Timor Tengah Utara Regency has been carried out in handwriting (conventional), which have some constraints such as taking a long time to processing grades, has a tendency to miscalculation if the student report card is lost or damaged, it does not have documentation/ back-up documents. For teachers who have sloppy handwriting, it will be difficult for a parent to read. One software that can be used in making student report cards is Microsoft Office Excel. This software is easy to understand and can overcome problems in making student report cards such as the length of time for processing grades, the tendency of grade processing error, difficulties in reading teacher writing by parents, and overcoming problems with documentation/backup documents. This service activity aims to provide training in making e-report card applications using Microsoft Excel for elementary school teachers in the Insana Fafinesu area, Timor Tengah Utara Regency. The methods used in this activity are workshops and ongoing mentoring. As a result, teachers better understand the functions in Microsoft Excel that are useful in the process of filling out student report cards, each teacher succeeds in making their own e-reports, and they agree that e-reports with Microsoft Excel are more efficient and effective than filling out report cards manually (conventional) and will use e-reports in their respective schools. The next plan for this service activity will be an application for Teacher Performance Assessment (TPA) and Employee Work Targets (EWT).
