Abstract

Abstract  Traffic accidents are a problem, especially on toll roadsbecause toll roads are designed as highways with high levels of comfort, smoothness and safety The number of accidents on Indonesian toll roads is still high. This research is expected to be able to address the above problems, especially the identification of accident-prone locations (black spot), accident characteristics, and proposed treatment at black spot.  The location of the study was the Jagorawi Toll Road (2015 - 2017) for 49 Km. Identification of black spot used the Accident Equivalent Rate (AEK) method, and identified locations prone to accidents (black spot) on Jakarta - Ciawi route were Km 08 - 09, Km 22 - 31, Km 33 – 37, and Km 39 – 43, while on Ciawi - Jakarta, tracks were Km 04 - 09, Km 21 - 23, Km 28 - 29, Km 34 - 35, Km 40 – 41, and Km 44 - 45. Identification of accident characteristics using data approach analysis and statistical analysis were fine weather, one-lane, 00.00 - 06.00, lack of anticipation, self-accident and mini bus. The proposed handling of accident-prone locations (black spot) to reduce the number of accidents is by Minimum Service Standards (MSS) of toll road safety, such as traffic signs, street lighting, rumble strips and other toll road safety equipment. Keywords : Black spot, Equivalent Accident Number, Accident CharacteristicsAbstrak Kecelakaan lalu – lintas merupakan salah satu masalah, khususnya pada jalan tol. Dikarenakan jalan tol dirancang sebagai jalan bebas hambatan dengan tingkat kenyamanan, kelancaran dan keselamatan tinggi, tetapi jumlah kecelakaan di jalan tol Indonesia masih tinggi. Penelitian ini diharap dapat menjawab permasalahan diatas, khususnya identifikasi lokasi rawan kecelakaan (Blackspot), karakteristik kecelakaan, dan usulan penanganan pada lokasi rawan kecelakaan. Lokasi penelitian yang diambil yaitu Jalan Tol Jagorawi (2015 – 2017) sepanjang 49 Km. Identifikasi lokasi rawan kecelakaan menggunakan metode Angka Ekivalen Kecelakaan (AEK), lokasi yang teridentifikasi rawan kecelakaan pada jalur Jakarta – Ciawi yaitu Km 08 - 09, Km 22 – 31, Km 33 – 37 dan Km 39 – 43. Sementara pada jalur Ciawi – Jakarta yaitu Km 04 – 09, Km 21 – 23, Km 28 – 29, Km 34 – 35, Km 40 – 41 dan Km 44 – 45. Karakteristik kecelakaan menggunakan analisis pendekatan data dan analisis statistik yaitu: Cuaca cerah, lajur satu, 00.00 – 06.00, kurang antisipasi, kecelakaan sendiri dan mini bus. Usulan penanganan yang dilakukan pada lokasi rawan kecelakaan untuk mengurangi jumlah kecelakaan adalah dengan Standar Pelayanan Minimum (SPM) bidang keselamatan jalan tol, seperti rambu lalu lintas, lampu penerangan jalan, pita pengaduh (rumble strip) dan kelengkapan lainnya.Kata kunci : Lokasi Rawan Kecelakaan, Angka Ekivalen Kecelakaan, Karakteristik Kecelakaan

Abstract

Factors that can affect employee performance, namely motivation and remuneration. One of the other important elements is leadership. This study aims to analyze the influence of motivation and remuneration on employee performance with leadership style as a moderating variable. This research is quantitative research. The population in this study was all employees in the ranks of the Technical Implementation Unit in Nusakambangan who came from 9 work units. Determination of respondents using purposive sampling method. The sample in this study is part of the total employee population in the ranks of the Technical Implementation Unit in Nusakambangan taken from each work unit. Research data were obtained through questionnaires. The data analysis technique used is a qualitative technique, namely an interactive analysis technique using the PLS (Partial Least Square) analysis tool. Based on the analysis and discussion, the following conclusions can be drawn: (1) Motivation has a positive effect on employee performance; (2) Remuneration has a positive effect on employee performance; (3) Leadership style does not moderate the influence of motivation on employee performance; (4) Leadership style does not moderate the effect of Remuneration on employee performance. Keywords: Motivation, Remuneration, Leadership Style, Moderating, Employees

Abstract

This study aimed to know the relationship between fixed asset revaluation and the perception of the company's performance in the future. This research can advise the government on the effect of fixed asset revaluation on company performance when the government repeats the policy of reducing fixed asset revaluation taxes during the economic recovery during the pandemic. The methodology used in this study was mixed methods research, which collected and analyzed qualitative and quantitative data. This research used primary data from focus group discussions (representatives of industrial entities, tax consulting practitioners, public accountants, regulators, and related authorities) and questionnaires distributed to 118 listed companies. This research found that implementing fixed asset revaluation in the company has an effect on increasing the company's performance perception in terms of accounting-based measures but did not necessarily increase the company's performance perception in terms of market-based measures. This research also explored the company's motives for revaluing fixed assets and the factors that became obstacles to implementing the fixed-asset revaluation tax incentive policy in Indonesia, including recommendations for implementing the fixed asset revaluation tax policy in the future.

Abstract

The management of used medical mask waste has become a significant issue due to the increased volume of waste during and after the pandemic. Medical mask waste contains cellulose compounds that can be converted into derivatives such as glucose, which are then processed into bioethanol as an alternative energy source. This study aims to hydrolyse medical mask waste using cellulase enzymes from Aspergillus Niger to produce glucose. The cellulase enzyme composition was varied (5 ml, 15 ml, and 25 ml) to determine the optimal hydrolysis conditions. The glucose produced was measured using DNS reagent assay with spectrophotometry at a wavelength of 540 nm. The highest amount of glucose was obtained under optimal conditions with 25 ml of cellulase enzyme after 48 hours of hydrolysis, amounting to 88.16 ppm. Subsequently, the glucose from hydrolysis was fermented using Saccharomyces cerevisiae, and the fermentation product was analysed for ethanol concentration using GC-FID. The products of fermentation ware 0.017% ethanol concentration from mask waste fermentation. Hydrolysis is an environmentally friendly alternative solution for handling mask waste.
