Abstract

Desa tangguh bencana (Destana) is a program aimed to make a village community prepared for and resilient to disasters. The Destana program was initiated by the National Disaster Management Agency (BNPB) decreed by the Regulation of the head of BNPB No. 1/2012. A village represents the bottom line in the government system and therefore the capacity building for disaster resilience starts from the villages. The number of villages in Central Java reaches 8559 villages, while BNPB, BPBD Province, BPBD Regency/City can only launch Destana on average 30 villages each year from 2013 - 2018. As a result, it takes quite a long time to forming Destana in all villages in Central Java. Therefore, the role of universities, in particular the state universities in forming Destana, is really needed. One of the activities in the formation of Destana was in the kuliah kerja nyata tematik program (KKN PRB) conducted in Purbalingga Regency in 2 villages that were prone to landslides. Provisioning for students refers to Perka BNPB Number 1/2012 by implementing 20 Destana indicators. Gunungwuled village and Panusupan village were the two villages where the KKN PRB done by 10 students each. For 45 days students could build several indicators, i.e. making disaster risk maps calculated based on hazard maps, vulnerability maps, and capacity maps. Next, they made a Landslide Contingency Planning Document with residents and relevant stakeholders. The Village Disaster Risk Reduction Forum consisting of various community components and the BPBD of Purbalingga Regency was also formed. Afterwards, the capacity building activities to the community against disasters were conducted. Finally, an early warning system for landslides in areas with potential landslides was created and warning signs for landslide-prone areas and evacuation route signs were installed. With the help of KKN PRB, the Panusupan village and Gunungwuled village have now become disaster resilient villages.

Abstract

It has been done a research about separation of regional-residual anomaly in Gravity method. This research compares the result of three methods i.e. moving average method, polynomial method, and inversion method. The computer program is created using a computer programming Matlab 7. From three methods that have been made, the separation results are compared withresults of separation by using Upward Continuation method. From the results of these comparisons will be available an excellent program of regional-residual anomali separation. The results show that in polynomial method of the order 4 obtained similar contour to the separation by Upward Continuation Software. So that the output of this separation will be treated again with Grav2DC software. The output of this software is the density of rock Grav2DC of the studyarea. Processing results obtained the minimum error of 1.85% for the separation by polynomial method, while for the method of Upward Continuation obtained minimum error of 2.22%. The results obtained show that the separation of regional-residual anomali by polynomial method is similar to separation by Upward Continuation method.

Abstract

The Covid-19 pandemic has caught the world's attention which hascaused various impacts on life. The spread of the virus takes placerapidly through droplets or physical contact to encouragegovernments to implement policies such as washing hands activitiesusing soap cleanly and correctly. Kalikajar village government asone of the villages that are exposed Covid-19 in Purbalingga alsohave appealed to the people to always washing hands with soap.However, the availability of hand washing facilities is still limitedand the conditions are alarming due to the lack of communitymaintenance. Therefore, as a form of community service, KuliahKerja Nyata (KKN) of Sebelas Maret University has initiative tocreate washbasin based on stepping system that can be used bypeople to get clean and healthy living. The service implementationstages include survey and identification of partner problems,preparation of problem solving frameworks, problem solving solutionprograms, implementation of service programs, monitoring andevaluation. Manufacture of washbasin through the manufacturingprocess and framework design, painting, assembly, and testing. Thewashbasin is distributed in several locations in Kalikajar Village,such as the Kalikajar Village Hall Office, Baitul Ghufron Mosque,and Baitul Muslimin Mosque. The distribution activites to severallocations had help from local residents, takmir mosques, and villageheads Kalikajar. Through this washbasin, the UNS KKN Team hopesthat the community and village government officials can develop andremind each other of the habit of washing hands so that it indirectlyhelps the government in preventing Covid-19 transmission in thesurrounding community.

Abstract

It has been conducted a research about Regional Seismic Disaster Index (RSDI) in Java Island by using seismic data from 1900 – 2006. RSDI is a index showing vulnerability seismic disaster in an area. The hight risk area is the highest risk, the low area is the lowest risk. The highest RSDI areas were Banten, Jawa Barat, and D.I Yogyakarta Provinces. While the lowest RSDI areas were DKI Jakarta and Jawa Tengah Province. Deviations standard value showed the moving RSDI value each region. Region with big RSDI value had high Seismic level were Banten , Jawa Barat, and D.I. Yogyakarta Province.

Abstract

ABSTRAK Penelitian ini bertujuan untuk mengidentifikasi sebaran dan ketebalan akuifer di wilayah timur Kabupaten Sragen menggunakan metode geolistrik tahanan jenis dengan konfigurasi Schlumberger. Data hasil pengukuran di lapangan diolah menggunakan perangkat lunak untuk analisis 1D serta pemodelan 2D dan 3D guna menginterpretasi litologi bawah permukaan dan karakteristik akuifer. Hasil interpretasi menunjukkan bahwa lapisan bawah permukaan tersusun atas tanah penutup (topsoil), lempung, lempung pasiran, pasir, pasir kerikilan, dan breksi. Zona akuifer umumnya diwakili oleh lapisan pasir dan pasir kerikilan. Pada kecamatan Sambirejo terdeteksi akuifer bebas pada kedalaman antara 1,17-35,7 m dengan ketebalan antara 9,56-31,36 m sedangkan akuifer tertekan pada kedalaman 26,4-90,8 m dengan ketebalan antara 35,8-56,3 m. Pada kecamatan Gondang terdeteksi akuifer bebas pada kedalaman antara 0,8-29,7 m dengan ketebalan antara 12,51-23,59 m sedangkan akuifer tertekan pada kedalaman 100-133 m dengan ketebalan antara 33 m. Pada kecamatan Sambung macan terdeteksi akuifer bebas pada ketertekanan antara 0,59-47,8 m dengan ketebalan antara 4,42-29,04 m, sedangkan akuifer tertekan pada kedalaman 20-121 m dengan ketebalan antara 33,4-93,7 m. Berdasarkan hasil pemodelan 3D, potensi airtanah terbesar terdapat pada lapisan pasir dan pasir kerikilan dengan volume masing-masing sebesar 8,735 × 10⁶ m³ dan 5,435 × 10⁶ m³. Penelitian ini menunjukkan bahwa konfigurasi geolistrik Schlumberger efektif dalam mendelineasi geometri akuifer dan menilai potensi airtanah, khususnya pada wilayah yang rentan terhadap kekeringan musiman seperti bagian timur Kabupaten Sragen. Kata kunci: airtanah, geolistrik tahanan jenis, konfigurasi Schlumberger, akuifer bebas, akuifer tertekan, Sragen.

Abstract

Dalam eksplorasi cadangan minyak dan gas bumi memiliki proses yang sangat panjang, yaitu dari penentuan daerah yang potensial mengandung hidrokarbon, survei seismik, eksplorasi, dan produksi. Salah satu tahapan dalam proses tersebut adalah proses well logging, yaitu untuk memperkirakan zona reservoir pada suatu lapangan atau sumur minyak. Penelitian ini bertujuan untuk mengidentifi kasi zona reservoir menggunakan data well logging dengan parameter berupa volume clay, porositas, dan saturasi air pada area Akimeugah di sumur KAU-1 dan KAU-2. Penelitian ini diharapkan dapat memberikan pemahaman mengenai pemanfaatan dan penggunaan sumur log. Metode yang digunakan adalah dengan menentukan koefi sien korelasi antara porositas efektif (PHIE) dengan porositas laboratorium dan mengukur kandungan lempung, porositas, dan saturasi air dalam formasi. Koefi sien korelasi porositas terhadap porositas laboratorium pada sumur KAU-1 adalah 0,739 dan sumur KAU-2 adalah 0,747. Hasil yang diperoleh dari penelitian ini dimungkinkan terdapat batuan tudung pada Formasi Piniya (sumur KAU-1 dan KAU-2) dengan zona reservoir antara Formasi Woniwogi hingga Toro pada sumur KAU-1 dan zona reservoar pada Formasi Woniwogi dan Toro pada sumur KAU-2. Kandungan saturasi hidrokarbon pada Formasi Woniwogi berkisar antara 0 - 86,51 % dan Formasi Toro 0 - 71,17 % di sumur KAU-1. Sedangkan di sumur KAU-2, pada Formasi Woniwogi saturasi hidrokarbon sekitar 0 - 86,71% dan Formasi Toro 0 - 87,08 %.
