Abstract

On the South Coast there is an increasing number of accidents every year. The criminological factor of the high number of traffic accidents in the Legal Area of the Pesisir Selatan Police is a factor of road conditions because Pesisir Selatan Regency has a geographical condition as a hilly plateau and is located along the southern coast of Sumatra. Another factor for community domesticated livestock is cows that are allowed to roam around without a leash. Efforts to Overcome Traffic Accidents in the Legal Area of the Pesisir Selatan District Police are carried out with several aspects, namely the engineering aspects of road maintenance and infrastructure, installation of markers, installation of warning lights (flip flop lights), installation of signs, and speed restrictions. The education aspect is carried out by improving motorist behavior, through appeals and training. Externally the obstacle faced is the lack of cooperation between the traffic police and other agencies related to traffic such as the transportation department and the nagari administration. The low level of legal awareness of road users in carrying out their work, namely driving their vehicles in accordance with good and correct driving operational standards, is often not applied by violating traffic regulations.

Abstract

Well integrity failures may arise during the production phase of a well in a field. Those failures could create a Sustained Casing Pressure (SCP), a pressure that is measurable at the wellhead that can not be bled-off. SCP has to be addressed carefully to avoid any uncontrolled fluid flow to other formation or to surface. To maintain SCP value from degrading the other barrier integrity, the pressure threshold should be known and maintained for each annulus in a well. The maximum pressure threshold known as Maximum Allowable Annular Surface Pressure (MAASP). This case study will calculate MAASP from three wells in X field using three known method as outlined in API RP90-2 and ISO 16530-1. API RP 90-2 define two methods in calculation MAASP (known as MAASP – Maximum Allowavle Wellhead Operating Pressure), Simple Derating Method (SDM) and Explicit Derating Method (EDM). The result then compared and evaluted to know the differences, trend of MAASP for each methods, and create a generalization of MAASP/depth for field rule of thumb. For A annulus, the MAASP obtained using API RP90-2 SDM and EDM method is always greater than that obtained using the ISO 16530-1 method. However, for B annulus, the MAASP obtained using the API RP 90-2 SDM method varies, occasionally being greater or less than the ISO 16530-1 method. While in C annulus, the MAASP obtained using the API RP 90-2 SDM and EDM methods is always less than the ISO 16530-1 method. The MAASP/depth generalization will be presented for MAASP ISO 16530-1.

Abstract

The planting program for Tanaman Obat Keluarga (TOGA; family medicinal plants) and ornamental flowers was a collaborative initiative between students of the Kuliah Kerja Nyata (KKN) Asoka Groups 1–4 and the community of Jorong Koto Panjang, aimed at improving environmental quality while fostering awareness of nature conservation based on citizen participation. This community service activity was implemented through TOGA planting every Saturday morning in Taman Asoka and ornamental flower planting in the afternoon at various strategic locations in the surrounding area. The results of the program’s implementation showed a significant increase in community participation, improvements in environmental aesthetics, and the development of collective awareness regarding the importance of sustainable environmental conservation. The program successfully created a positive synergy between students and the local community in realizing a healthy and green environment, while also providing a replicable model for environment-based community service programs in other regions.
