Purpose – The purpose of this paper is to know the types of mangrove and the status of the conservation of mangrove ecosystems in the area of Krueng Reuleng River, Leupung, Aceh Besar Regency.

Design/Methodology/Approach – Data collection on mangroves was retrieved using a Quadrat Sampling Method, the acquisition of information about the status of conservation of mangrove ecosystems was done using the interview method.

Findings – The results showed that there are four types of mangroves, and mangrove ecosystem conservation efforts have not been made by the people of Leupung. The conclusions of this study are as follows: the types of mangroves found in the area of Krueng Reuleng River are Nypa fruticans, Sonneratia alba, Acrostichum aureum, and Thespesia populnea. Conservation measures have not been undertaken to preserve the mangrove ecosystem in the area of Krueng Reuleng River.

Research Limitations/Implications – The location can be used as a site of practical research on the type of mangroves in the Krueng Reuleng River area for students studying biology.

Originality/Value – In addition to upgrading the data on the types of mangroves, this paper could be a reference for any relevant field.

The construction industry is one of the least automated industries. In the aspect of automation, the technical understanding is very dominant. Focus has mostly been on tools, robots and industrialisation. sociomaterial design shows us that what may first appear technologically deterministic can be replaced and actually call for reinvisioning the traditional focus. The purpose of this study is to introduce the agency of a sociomaterial designer in construction.

This is a conceptual paper with an empirical example. To understand the sociomaterial complexity and dynamics of automation, practice theories are applied. To test this approach, the authors give an example from a Danish (global) supplier engaged in a development project about technical aid (tools) in mounting and assembling gypsum walls.

The sociomaterial-designer can help to understand and make innovation happen when doing automation in construction; as the centre of innovation in construction processes, she works all day with practice, together with practitioners, focusing on material arrangements as located not only in practice, but also in the artefacts. She can help the supplier of construction materials in understanding different professional practices and the transformation to use smarter tools.

This research is within a new practice domain “sociomaterial-design” and it has to follow up with an empirical study that covers a development project with a sociomaterial-design approach.

Developing competences (agency) as a sociomaterial-designer when linking the sociotechnical understanding of Automation with practice.

This research showcases how sociomaterial perspectives can inform automation in construction.

In this chapter, the author examines the way in which the purchase and delivery infrastructure of darknet cryptomarkets shapes the experience of opiate drug use and dependence. It uses the concept of social time and posits that the illicit drug distribution system reshapes two temporal dimensions shaping the experience of drug users. There is the experience of time located in the pharmacology of the drug and in the body of the drug user, which evokes experiences of withdrawal and dependence. Then there is the socio-technical embedding of the delivery system and governance structures which support or impinge on the autonomy of the user. This ‘drug time’ is both a benefit and a cost of engaging in cryptomarket use. The market infrastructure can give users the opportunities to more carefully manage their drug time, while also creating new risks of non-delivery that can sharpen experiences of dope sickness. The author concludes that the growing professionalisation, digitisation, and commercialisation of the drug market increasingly embed drug time in material infrastructures mediated through technical systems.
