Abstract

Desa Limbasari secara geografis terletak di Kecamatan Bobotsari Kabupaten Purbalingga. Desa Limbasari merupakan salah satu desa wisata yang baru di Kabupaten Purbalingga. Desa ini mempunyai potensi yang besar untuk dikembangkan sebagai destinasi wisata dalam segi wisata kebumian dan geoheritage. Daya tarik wisata yang ada berupa River Tubing, landscape pegunungan batuan gunung api yang terdapat batu jasper hijau “nogo sui”, dan situs kebudayaan prasejarah. Di samping itu keunikan budaya serta sejarah masyarakat juga menjadi daya tarik bagi masyarakat perkotaan. Tujuan dari pengabdian masyarakat adalah mengulas kelayakan geosite dan geomorphosite di Desa Limbasari sebagai sebuah solusi bagaimana memanfaatkan kekayaan geologi beserta berbagai dinamikanya untuk kegiatan wisata edukasi dan ekonomi yang berwawasan lingkungan. Metode yang digunakan adalah pemetaan potensi geologi sebagai kawasan wisata, inventarisasi pada lokasi yang mempunyai cagar budaya dan sejarah serta wawancara dengan pihak terkait dan studi literatur. Dari hasil kelayakan di kawasan wisata Limbasari mempunyai nilai kelayakan antara 47.5% - 73.5%. Dengan demikian, Kawasan Desa Wisata Limbasari, Kabupaten Purbalingga layak menjadi objek geowisata dengan aspek penilaian didasarkan pada nilai kuantifikasi berbagai keindahan antara alam dan proses geologi yang mengontrol terbentuknya obyek geowisata tersebut.Limbasari Village is geographically located in Bobotsari Subdistrict, Purbalingga Regency. Limbasari Village is one of the new tourism villages in Purbalingga Regency. This village has great potential to be developed as a tourist destination in terms of earth tourism and geoheritage. The tourist attractions are River Tubing, mountainous volcanic mountain landscape with green jasper stone "nogo sui", and prehistoric cultural sites. In addition, the cultural and historical uniqueness of the community is also an attraction for urban communities. The purpose of this study is to review the potential of Geotourism and geoheritage in the Village of Limbasari as a solution to how to utilize the rich geological and cultural sites along with various dynamics for educational activities that are environmentally friendly education and economy. The method used in this study is the mapping of geological potential as a tourist area, an inventory of locations that have cultural and historical reserves as well as interviews with relevant parties and literature studies. From the results of research in the tourist area Limbasari has a feasibility value between 47.5% - 73.5%. Thus, the Limbasari Tourism Village Area, Purbalingga Regency deserves to be a geotourism object with the assessment aspect based on the quantification value of various beauties between nature and the geological process that controls the formation of the geotourism object.

Abstract

The hot asphalt surface layer is layered and has different functions in the pavement structure. In addition to being able to distribute the vertical load of the vehicle, it must also be able to withstand the lateral load of the vehicle. The lateral load of the vehicle that is too large causes a shear force which will have an impact on the release of the bond between the layers of hot asphalt mixture. Therefore, it is necessary to conduct research to determine the shear strength between layers of hot asphalt mixture. Several factors that cause the level of bonding strength between layers of hot asphalt mixture are the distribution of the tack coat, the setting time, the type of tack coat, and the presence of adhering dirt. The purpose of this study was to determine the effect of variations in the distribution of tack coat 0.25 and 0.35 l/m2 and setting time of 60, 90, and 120 minutes on the shear strength between layers of hot asphalt mix asphalt concrete wearing course (AC-WC) and asphalt concrete base course (AC-BC). The laboratory testing method selected by using modified soil shear test equipment. The test results show that the number of distributions and the length of setting time will cause an increase in the shear strength between the hot asphalt mixture. The maximum shear strength in the distribution of 0.25 l/m2 is 0.59 kg/cm2 and the distribution of 0.35 l/m2 is 0.64 kg/cm2 with a setting time of 120 minutes. It can also be concluded that setting time has a more significant effect on shear strength between asphalt pavement layers than the distribution of tack coat.
