This community development paper is related to socioeconomic issues in East Nusa Tenggara (NTT), an area known for its high rates of poverty and child malnutrition. Wahana Visi Indonesia launched an Inclusion Community Development Program to empower underprivileged households and small farmers in response to these issues, working with the PPM School of Management. Workshops that promoted opportunity recognition, business planning, and digital marketing were used to help participants develop their entrepreneurial abilities during the February 2025 event. Explanation, coaching and mini case studies are a technique used in community development to comprehend and resolve issues.. The results show that despite efforts to include underrepresented groups, participants' understanding of entrepreneurial principles was hindered by educational gaps. By highlighting the value of cooperatives and ongoing training for sustainable economic growth in NTT, the program showed promise for fostering resilience and inventiveness in local economies. Suggestions for upcoming projects include continued assistance for collaborative growth and customized instruction to improve participants' business savvy

The terrorism threat nowadays is a formidable challenge due to the phenomenon of terrorist perpetrators that are actually part of company employees. Thus, selecting and recruiting new employees process is a strategic matter in preventing the entry of terrorist networks into the company. PHENC which is a national vital object and subsidiary of the oil and gas company, PT Pertamina (Persero), has the potential to become a terrorist operational target. It refers to the statements of the ex-combatants interviewed in this study. The terrorist team have data of pipelines, wells, oil and gas refineries throughout Indonesian companies. Therefore, PHENC needs to have a strategy to prevent the terrorism network in the recruitment and selection of new employees. This study is applied research using qualitative and narrative approach with detailed situation of the research object. Qualitative data were collected by written interview method with PHENC management representatives and using descriptive analysis techniques. The analysis result shows that currently PHENC has not conducted Background Check in the recruitment and selection process of new employees. Based on the PHENC risk register, recruitment and selection are listed as secutity threat risks. The design of the proposed strategy to prevent the terrorism network in recruitment and selection of new employees consists of three parts: part for new permanent employees, for new outsourcing employees and the implementation of integrated security management system (SMS).

The combination of electronic sources operating at high frequencies and modern microwave instrumentation has enabled the recent development of chirped-pulse spectrometers for the millimetre and THz bands. This type of instrument can operate at high resolution which is particularly suited to gas phase rotational spectroscopy. The construction of a chirped pulse spectrometer operating at 200 GHz is described in detail while attention is paid to the phase stability and the data accumulation over many cycles. Validation using carbonyl sulphide has allowed the detection limit of the instrument to be established as function of the accumulation. A large number of OCS transitions were identified using a 10 GHz chirped pulse and include the 6 most abundant isotopologues, the weakest line corresponding to the fundamental R(17) transition of 16 O 13 C 33 S with a line strength of 4.3 x 10-26 cm-1 /(molec.cm-2). The linearity of the system response for different degrees of data accumulation and transition line strength was confirmed over 4 orders of magnitudes. A simple analysis of the time domain data was demonstrated to provide the line broadening coefficient without the need for conversion by a Fourier transform. Finally, the pulse duration is discussed and optimal values are given for both Doppler limited and collisional regimes.

In this paper, the use of a monitoring companion is proposed to more efficiently collect the process information during the tuning of industrial systems, and therefore to assist the system integrator in the optimization process for complex robotic installations. The monitoring companion consists of an industrial manipulator (monitoring robot) and a Unity-ROS framework for controlling it. We discuss in this paper the features that allow the solution to be re-used in different industrial application thanks to its compatibility with ROS. In particular, we present the approach based on admittance virtual fixtures and how we use such abstraction to track a moving target (it could be the end-effector of another robot for example). Moreover, the concept of varying compliance is introduced as a way to influence the motion of the monitoring robot on the virtual fixtures in the presence of obstacles. The experiments have been conducted in simulation as well as on real hardware to test the accuracy of the system at respecting the virtual fixtures with both a static and a moving monitoring target, although in the current implementation the varying compliance was not included in the experiments.

Planning and monitoring the manufacturing of high quality one-of-a-kind products are challenging tasks. In the implementation of an industrial system, the commissioning phase is typically comprised of a programming phase and an optimization phase. Most of the resources are commonly invested in the optimization of the process. The time and cost of the implementation can be reduced if the monitoring system is not embedded in the industrial process, but kept instead as a decoupled task. In this paper we present a framework to simulate and execute the monitoring task of an industrial process in Unity3D, without interfering with the original system. The monitoring system is made of external additional equipment and is decoupled from the industrial task. The monitoring robot's path is subject to multiple constraints to track the original process without affecting its execution. Moreover, the framework is flexible thanks to the Unity-ROS communication so that the monitoring task can be carried on by any ROS-compatible device. The monitoring system has been applied to a robotic system for heavy, multi-pass TIG welding of voluminous work-pieces. The results of the implementation show that the constraints for monitoring were satisfactory in the 3D environment and capable for real robot application.

Recently industrial robot systems are introduced widely even in the small and medium size enterprises. However, it is difficult for them to employ professional engineers permanently. Then, they need to depend on outside to maintain industrial robots. Therefore a remote operation support system for industrial robots is proposed. Visual and auditory feedback is often used. However, a perception of the information might be limited if different kinds of information in particular sense modality is delivered at the same time. To solve the problem, we proposed a tactile interface which uses tactile information. This paper evaluates the usefulness of the vibrotactile information using the glove-type interface. The experimental results showed that vibrotactile information could not improve work efficiency. However it enable an operator to concentrate other information without increasing a workload. Therefore vibrotactile information is useful.

An attempt is currently being made to widely introduce industrial robots to Small-Medium Enterprises (SMEs). Since the enterprises usually employ too small number of robot units to afford specialized departments for robot maintenance, they must be provided with inexpensive and immediate support remotely. This paper evaluates whether the support can be provided by means of Cognitive Info-communication – communication in which human cognitive capabilities are extended irrespectively of geographical distances. The evaluations are given with an aid of experimental system that consists of local and remote rooms, which are physically separated – a six-degree-of-freedom NACHI SH133-03 industrial robot is situated in the local room, while the operator, who supervises the robot by means of audio-visual Cognitive Human-Machine Interface, is situated in the remote room. The results of simple experiments show that Cognitive Info-communication is not only efficient mean to provide the support remotely, but is probably also a powerful tool to enhance interaction with any data-rich environment that require good conceptual understanding of system's state and careful attention management. Furthermore, the paper discusses data presentation and reduction methods for data-rich environments, as well as introduces the concepts of Naturally Acquired Data and Cognitive Human-Machine Interfaces.

This paper proposes a vibrotactile glove interface that enabled users to perceive tactile sensations of virtual objects. The proposed vibrotactile interface was designed to be easy-to-use, easily portable, and lightweight. Active touch might also be useful to realize informative tactile communication. To provide tactile stimuli based on movement of the fingers, five bending sensors were installed on the glove. In this study, the relationship of the correspondence between vibrotactile stimuli and tactile mental imagery was investigated. Subjects' mental impressions of vibrotactile stimuli were measured by using the semantic differential (SD) method. Distinctive imagery from subjects' answers was extracted for factor analysis. After that, a vibration stimuli model was applied to active touch. The tactile mental imagery of users was evaluated for both passive and active touches.

Supercontinua generated in highly non-linear fibers by ultrashort-pulse lasers can be used for high resolution Fourier transform absorption spectroscopy. The practical advantages of these bright ultrabroadband light sources for spectroscopy are reported in the near-infrared region. A Cr^4+:YAG femtosecond laser broadened by an extruded soft-glass photonic crystal fiber, emitting from 1200 to 2200 nm and from 675 to 950 nm, provides a spectral radiance being 1x10^5 times higher than that of a 3000 K blackbody and 10^2 times higher than that of a synchrotron radiation. The C_2H_2 and NH_3 overtone spectra are recorded using this source within a few seconds.
