Abstract

To ensure the quality of education in vocational schools (Sekolah Menengah Kejuruan or SMK), the government intervenes through the Skills Competency Test (Uji Kompetensi Keahlian or UKK). During the UKK process for SMK Budi Bangsa students in March 2018, it was found that the participants generally had not yet mastered the material to be tested, specifically the use of topographic mapping equipment. This is likely due to the insufficient availability of adequate facilities and infrastructure at SMK Budi Bangsa. Therefore, training on the use of topographic mapping equipment is necessary to better prepare SMK Budi Bangsa students for a similar exam the following year. The topographic mapping training, using auto level and theodolite tools, aims to enhance students' knowledge and skills in accordance with the equipment usage guidelines and refer to the Code 1556 Vocational Practice Exam Assessment Sheet. The topographic mapping training was conducted at SMK Budi Bangsa from January 29 to February 4, 2019. The method used involved theoretical presentations on topographic mapping in general and the specific use of auto level and theodolite tools, as well as practical exercises on the usage of these tools, measurement and data processing, and the creation of topographic maps. The training activities were attended by 27 students, consisting of 14 students from class X, 3 students from class XI, and 10 students from class XII. From only 7.4% of the participants who initially possessed the knowledge and skills according to the first two stages of the reference before the training, they achieved improvement, with all participants acquiring the knowledge and skills according to all stages of the planned reference.

Abstract

The Kalumpang Formation was deposited in a delta plain setting. A Middle to Late Eocene age (Proxapertites operculatus zone) was inferred from palynological analysis, with a paleoenvironment in a coastal plain setting with a strong terrestrial influence. Samples from the Kalumpang Formation indicate a marginal to early mature stage for hydrocarbon generation. It is mostly composed of gas-prone to oil and gas-prone Type III kerogen facies. The biomarker character of both the rock and oil samples suggests a terrestrial origin, with a significant contribution of estuarine or bay organic material. The oil derives from a non-carbonate lithology, while the rock samples are from carbonate/calcareous shale origin. The abundance of oleanane compound and C30 resins suggests higher plant angiosperm input of Late Cretaceous or younger age for both the rock and the oil samples. The oil seep contains more abundant oleananes compared to the carbonaceous mudstone of the Kalumpang Formation. This suggests that the oil originated from more marine facies than the rock samples, which were deposited in a delta plain setting. This study demonstrated the agreement of depositional environment interpretation and age assessment between lithofacies, palynological, and organic geochemistry analysis.

Abstract

Permukaan tanah tidak selalu rata atau memiliki perbedaan elevasi yang menyebabkannya miring di tempat yang berbeda. Salah satu bencana alam yang sering terjadi pada lereng buatan maupun alam adalah tanah longsor. Tujuan dari penelitian ini adalah untuk mengetahui nilai faktor keamanan (FK) dan sifat material sampel tanah untuk analisis stabilitas lereng. Program komputer GeoStudio digunakan dalam studi analisis faktor lereng aman dengan memasukkan data geometri lereng dan parameter yang diperoleh dari uji laboratorium. Pengolahan data menggunakan uji laboratorium untuk mengetahui sifat fisik dan mekanik tanah yang meliputi berat jenis, compaction standard proctor dan unit weight. Hasil uji laboratorium dari sifat mekanik tanah yaitu uji kuat geser (direct shear). Keadaan geometri lereng memiliki panjang toe 8 m, panjang crest 10 m, tinggi lereng 7 m dan kemiringan lereng 85˚. Material propertis dari geometri lereng terdiri dari kohesi 0,161 kg/cm2, sudut geser dalam 3,8˚ dan gsat sebesar 1,263 gr/cm3. Hasil analisis faktor keamanan (FK) dari penggunaan metode bishop menghasilkan nilai faktor keamanan 0,126.  Ketidakstabilan lereng dipengaruhi oleh lebih besarnya gaya penggerak dibanding gaya penahan sehingga dapat berpotensi terjadinya longsor. Hasil dari perolehan yang didapat dikatakan bahwa lereng daerah penelitian memiliki kerentanan gerakan tanah yang tinggi karena nilai faktor keamanan ≤1,2 menurut Ward.

Abstract

Gerakan tanah dan batuan merupakan permasalahan yang dapat menimbulkan kerugian bagi korbannya, baik materil maupun jiwa. Materialnya dapat berupa tanah dan atau batuan yang dapat menutup akses jalan, terlebih jika dalam volume yang besar. Pemetaan potensi gerakan tanah dan batuan penting dilakukan sebagai tahap awal dalam memberikan rekomendasi solusi pada pencegahan dan penanggulangan gerakan tanah dan atau batuan. Pengabdian ini dilakukan dengan mengidentifikasi dan mengamati kondisi material di lapangan, baik yang sudah terjadi gerakan tanah maupun yang memiliki potensi terjadinya gerakan tanah. Pengamatan dilakukan dengan menyusuri ruas jalan raya Doi-Doi – Palludda untuk menemukan bekas gerakan tanah dan potensinya dengan melakukan pengukuran geometri, pengukuran arah lereng, dan pengamatan kondisi material (kepadatan dan pelapukan). Pengamatan dilakukan pada sembilan lokasi kemudian disajikan ke dalam peta potensi gerakan tanah. Sebagian besar lokasi pengamatan menunjukkan peran air memegang peranan penting dalam menjaga lereng dalam kondisi stabil sehingga gerakan tanah batuan dapat dihindari dan meminimalkan risiko yang dapat terjadi. Perhatian pemerintah dalam penanganan hal tersebut tentu sangat dibutuhkan agar tidak menimbulkan kerugian, apalagi korban jiwa. Penanganan setelah terjadi gerakan tanah dan kerusakan parah pada ruas jalan ketika mengalami penurunan akan membutuhkan biaya dan tenaga yang lebih besar. Pengabdian ini diharapkan dapat menjadi rujukan atau sumber informasi bagi masyarakat pengguna jalan dan pemerintah pada pengetahuan mengenai potensi gerakan tanah dan atau batuan. Pengamatan lanjutan perlu dilakukan untuk mendapatkan rekomendasi penanganan yang benar dan sesuai dengan potensi gerakan yang telah diamati.
