Abstract. An earthquake with a magnitude of Mw=7.5 that occurred in Sulawesi, Indonesia, on 28 September 2018 triggered liquefaction and tsunamis that caused severe damage and many casualties. This paper reports the results of a post-tsunami field survey conducted by a team with members from Indonesia and Taiwan that began 13 d after the earthquake. The main purpose of this survey was to measure the run-up of tsunami waves and inundation and observe the damage caused by the tsunami. Measurements were made in 18 selected sites, most in Palu Bay. The survey results show that the run-up height and inundation distance reached 10.7 m in Tondo and 488 m in Layana. Inundation depths of 2 to 4 m were common at most sites and the highest was 8.4 m in Taipa. The arrival times of the tsunami waves were quite short and different for each site, typically about 3–8 min from the time of the main earthquake event. This study also describes the damage to buildings and infrastructure and coastal landslides.

In the global world reality the success of large companies depends on a permanent logistics evaluation. But to measure the stage of logistics level, a methodology, models and references are required. The national and international performance measurement in logistics activities references was used. This was carried out in order to develop a field survey, using a methodology, model and references described in this paper. Also, survey results on the use of formalization in logistics are analyzed, i.e. how the logistics organization influences the whole structure to improve the supply chain management.

At present in China, the use of the transient electromagnetic method (TEM) is emerging as a leading geophysical technique for exploration of water-filled zones in coal mines. These zones are more conductive than the host coal and are easy targets to map. However, there is a growing interest for the investigations of double-layered or multi-layered mined-out zones. Therefore, it is necessary to study the feasibility of TEM's abilities to detect double-layered, water-filled voids. In this study, the basic hydrogeological conditions of a survey area, located in the northern China, are described. The corresponding geophysical models of the single- and double-layered water-filled zones are developed from borehole logging data. Then, forward calculations of different models are carried out with 1D numerical simulations. The modeling results show that it is feasible for TEM to identify these types of targets under certain conditions, including instrument sensitivity, low resistivity for the water-filled zones, and shallower depths. Moreover, the field survey for locating double-layered water-filled zones in coal mines in the Datong region of Shanxi Province is verified by well drilling.

To assess crucial stresses to fish survival in suburban streams, a Life Cycle Risk Assessment (LCRA) was developed and verified by comparing with field survey results. In LCRA, 8 stresses produced by human activities were taken into consideration, referring to the literature. Field survey was conducted over 2 years to identify the present existence and distributions of fishes in 3 streams, which have different pollution levels and morphologies. Field survey results demonstrated that species of fishes and their populations were different in 3 streams and varied with location. Crucial stresses frequently identified by the LCRA were depletion of dissolved oxygen (DO), disappearances of habitats (e.g. deep and shallow), disappearance of spawning area, and existence of obstructions in the streams. Furthermore, most LCRA results regarding existence or non-existence of 15 fishes at 7 different sites were fairly in good agreement with field survey results. From these results, we concluded the present LCRA would be a useful tool in assessing crucial stress as well as in predicting fish species that are able to survive in streams.

Access Pathway

In line with the government's program to strengthen tourism destinations in Indonesia, many tourism villages have been initiated, including Kulon Progo Regency. The needs of people to relieve fatigue by visiting tourist attractions, encourage the growth of tourist villages. The existence of a tourism village encourages the growth of typical souvenirs of the tourist village. Jatirejo is one of the villages in the Lendah sub-district, Kulon Progo, which is located at 7o93'22" south latitude and between 110o23'08" east longitude. Jatirejo has an area of 635.89 ha or 17.87% of the area of Lendah District (3,559.19 ha). The location of Jatirejo is close to access pathway of NYIA Airport, so it has great potential to become one of the tourism destinations. It is necessary to develop a tourist village by recognizing the agroindustry product potency owned by Jatirejo. This Community Service aimed to recognize and to document the agroindustry product potency of villages, as a first step in the development of local souvenirs and to support the development of Jatirejo Tourism Village. The method used was a field survey and plot the survey results on a map of Jatirejo Village using Corel Draw software. Based on the results of a survey of 5 hamlets in Jatirejo Village, the potential of processed foods that might be developed including emping melinjo, rice plates, catfish product, benguk/koro tempeh, coconut fiber broom, and also chicken cage.
