Environmental impact analysis of batik natural dyes using life cycle assessment

The use of natural dyes for batik dyeing is fewer than synthetic dyes because of its limitations in the application such complexity in manufacture and usage. For ease of use, natural dyes need to be processed into instant products. Extract of natural dyes are generally produced in liquid form that are less practical in long-term use. Dye powder obtained by drying the liquid extract using spray dryer. Production process of liquid natural dye is simpler and require less energy but need more energy for transporting. It is important to know which type of natural dyes should be produced based on their environmental impact. This research aim to compare environmental impact between liquid and powder natural dyes and also to find relative contribution of different stage in life cycle to total environmental impact. The appropriate method to analyze and compare the environmental impacts of powder and liquid natural dyes is Life Cycle Assessment (LCA). The “cradle to grave” approach used to assess environmental impact of powder and liquid natural dyes of Jalawe rind throughout production process of natural dyes, distribution and use of natural dyes for coloring batik. Results of this research show that powder natural dyes has lower environmental impacts than liquid natural dyes. It was found that distribution, mordanting and packaging of liquid dyes have big contribution to environmental impact.The use of natural dyes for batik dyeing is fewer than synthetic dyes because of its limitations in the application such complexity in manufacture and usage.

Model of pre-positioning warehouse logistics for disaster eruption of Mount Merapi in Sleman Yogyakarta

In generally, mitigation of natural disasters in Indonesia still be responsive and reactive to sudden disasters occur. It shows that disaster management system is not well coordinated and cant be quickly response to disaster mitigation. In this case, disaster management system need to be supported by manageable disaster logistics system. This study aims to identify the criteria for determining the location of a catastrophic disaster logistics warehouse in Sleman, Yogyakarta, and determine alternative logistics warehouse location. This research used AHP and Fuzzy-TOPSIS to select the criteria and sub-criteria in determining the location of the warehouse logistics, while Fuzzy-TOPSIS used to rank the final location, so that the optimal location selected. The results showed that the most important criterion is the stability of the national, sub importantly, social circumstances and the location chosen for the logistics warehouse is Candibinangun.

Q inventory model with product expiry and product return on pharmaceutical products at hospital kardinah

The existence of inventory for a company is essential and unavoidable, but its presence is often regarded as a waste. Therefore, inventory control is an important thing to do in order to optimally fulfilled product demand. Pharmaceutical unit is an installation support for the Hospital to provide drugs. Medicine is one of perishable products. Recently at department of pharmaceutical logistic in a Hospital, there are drugs that were not sold for 3 consecutive months a.k.a deathstock due to its slow-moving stock, so that the drugs stored too long in warehouse and lead to great inventory cost due to large storage cost. Drugs which will expire should be return to the supplier with an average lead time of five months, this raised the risk of stockout and high opportunity lost on the sale of these drugs. It is necessary to control supply by considering probabilistic demand, expiry and product return so it can minimize total cost of the inventory. The purpose of this research was to determine the optimal order quantity of drugs and minimizing the quantity of expired drugs to return. From model development and numerical calculations can be concluded that the inventory model was developed on this research solved the inventory problems which has probabilistic demand factor, expiry factor and product return factor.

Effect of speedometer positioning: Distraction and workload while driving

One of the automotive design car developments is speedometer position change. There are two speedometer positions used by the public, i.e. in behind the steer and on the center of dashboard. Speedometer position affects the visual scanning time information on the speedometer (glance). Total Time glances are very influential to distraction and workload while driving. The purpose of this study is to determine the position of the speedometer that minimizes distraction and workload while driving. The type of this research is a real experimental study using real cars on the road. The number of respondents involved was 12 peoples. Distraction data were obtained from the total glances while driving (using cameras). While the workload while driving was obtained from a questionnaire adapted from DALI (Driving Load Activity Index). Based on the analysis of total glances and questionnaires, speedometer on the center of dashboard showed a higher total glances and higher average value of global demand attention, visual demand, as well as stress. Consequently, in order to maintain safety and comfort in driving, the speedometer position in behind the steer is better than on the center of dashboard.

PERANCANGAN SISTEM PENILAIAN KINERJA KARYAWAN DAN PEMBERIAN REWARD MENGGUNAKAN ANALYTICAL HIERARCHY PROCESS (AHP) DAN FUZZY SYNTHETIC DECISION APPROACH (Studi Kasus : Karyawan Administrasi Universitas Diponegoro)

Penilaian kinerja merupakan proses yang penting dalam sumber daya manusia, karena dari hasil penilaian kinerja akan terukur kompetensi, perilaku kerja dan hasil kerja karyawan dalam periode waktu tertentu sebagai dasar pertimbangan dalam pertimbangan keputusan di bidang sumber daya manusia. Universitas Diponegoro juga melakukan pengukuran kinerja untuk karyawan kontrak, dari hasil penilaian tersebut akan diberikan reward berupa kompensasi langsung yang diberi nama Tunjangan Perbaikan Kinerja (TPK), dan tahun 2014 TPK berubah nama menjadi Tunjangan Perbaikan Penghasilan (TPP). Sistemxa0 penilaian saat ini masih berfokus pada aspek kedisplinan, sehingga hasil yang didapatkan belum seluruhnya menggambarkan kondisi karyawan. Maka dari itu,xa0 disusunlah penilaian kinerja yang terdiri dari 6 kriteria utama dan 19 subkriteria yang dibangun dari model penilain kinerja ”Annual Performance Appraisal-Temporary Employee (Classified or Administrative and Professional) University of Texas Dallas”. Dari hasil penelitian pembobotan yang dilakukan dengan menggunakan metode AHP (Analytichal Hierarchy Process) diperoleh bobot untuk kriteia kehadiran/ketepatan waktu (0.248), inisiatif (0.234), tanggung jawab dan ketergantungan (0.194), kualitas kerja(0.139) pengetahuan pekerjaan (0.111) dan hubungan interpersonal (0.075). Lalu dilakukan penilaian dengan pendekatan Fuzzy Synthetic untuk mendapatkan besar TPP. Dari perhitungan TPP yang terbesar ialah terbesar ialah Rp. 979,605,sedangkan TPP yang terkecil Rp.396,000. Besar-kecilnya pemberian TPP dipengaruhi oleh nilai jabatan yang dihasilkan Kata Kunci : penilaian kinerja; AHP; fuzzy shyntetic decision approach; reward Abstract Performance appraisal is an important process in human resources, because of the results of the performance appraisal will be measurable competencies, workplace behavior and employee performance within a specified time period as a basis for consideration in the consideration of the decision in the field of human resources. Diponegoro University also conduct performance measurements for a contract employee, from the results of the assessment will be given a reward in the form of direct compensation, named Performance Improvement Allowance (TPK), and in 2014 changed its name TPK Repairs Allowance Income (TPP). The scoring system is still focused on the aspects of discipline, so that the results obtained are not completely describe the condition of the employee. Therefore, formulate performance assessment consisting of 6 main criteria and 19 sub-criteria are built from a model for assessing the performance of Annual Performance Appraisal-Temporary Employee (Classified or Administrative and Professional) University of Texas Dallas. Based on the result on the research carried out by using the weighting method AHP (Analytichal Hierarchy Process) weights obtained for kriteia attendance / punctuality (0248), initiative (0234), responsibility and dependence (0194), the quality of work (0139) knowledge work (0111) and interpersonal relationships (0075). Then an assessment with Fuzzy Synthetic pendekatan to get big TPP. TPP is the largest of the calculation is the biggest is Rp. 979.605, while the smallest Rp.396,000 TPP. The amount of the provision of the TPP is affected by the value of the resulting position. Keywords: performance appraisal; AHP; fuzzy shyntetic decision approach; reward

Achieving cleaner production in SMEs batik toward innovation in production process

This study aims to analysis and identify some options of innovation in the process of making batik in order to implement the concept of cleaner production by presenting the result-type of research of one Small Medium Enterprise (SMEs) Batik which is located in the Pekalongan. Based on the types and the amount of waste generated at each stage, this study proposes a set of alternative of innovation for the implementation of cleaner production in the process of making batik, namely recycle the collected wet wax from “pelorodan” process, reuse the wastewater from the dyeing process, reuse the droplets of wax from the process stamping, reuse the water from “pelorodan” process as long as 3 days before disposal, reuse the water from washing and flushing process as long as 2 days before disposal, and reduce the use of synthetic dyes with natural dyes. Unless the last alternative, all alternatives of innovation which were proposed in this study could give positive net benefit to the enterprise.
