ABSTRAK Metode penambangan dengan kapal keruk (dredging) termasuk ke dalam metode penambangan tambang terbuka aquaeous, karena mekanismenya yang mirip dengan penambangan pada tambang terbuka, hanya saja kegiatan penggaliannya dilakukan di bawah permukaan air dengan alat penggalian berupa ember (bucket). PT. Timah Tbk sebagai salah satu perusahaan tambang yang memiliki ratusan Izin Usaha Pertambangan (IUP) Operasi Produksi untuk komoditas timah dan sebagai satu-satunya perusahaan yang memiliki beberapa unit kapal keruk, menggunakan armadanya dalam kegiatan penambangan endapan timah alluvial lepas pantai (offshore) di perairan Pulau Bangka dan Kepulauan Riau. Terdapat tiga jenis sistem penggalian pada operasional kapal keruk, yaitu sistem vertical digging, sistem benches dan sistem kombinasi. Sistem penggalian yang digunakan  dapat mempengaruhi keberhasilan aktivitas penambangan pada kapal keruk yang dinilai berdasarkan  parameter yaitu nilai Laju Pemindahan Tanah (LPT) dan kemiringan lereng (slope) yang dibentuk oleh proses penggalian. Analisis sistem penggalian bertujuan untuk melihat sistem penggalian manakah yang paling tepat untuk diterapkan pada kapal keruk sesuai dengan lokasi kerjanya. Data yang digunakan dalam analisis sistem penggalian merupakan data yang diperoleh langsung selama proses penggalian Kapal Keruk 21 Singkep 1 pada lokasi kerja Bulan Mei 2019. Data tersebut terdiri dari: nilai penekanan ladder, kecepatan naik turun ladder dan kecepatan tarik kawat. Kemudian pengolahan data dilakukan sehingga didapat nilai Laju Pemindahan Tanah (LPT) dan kemiringan lereng (slope) yang terbentuk dari proses penggalian menggunakan ketiga sistem penggalian yang ada. Analisis data dilakukan sehingga didapat poin-poin yang berkenaan dengan  kelebihan dan kekurangan masing-masing sistem penggalian. Berdasarkan perbandingan tersebut maka dapat ditentukan sistem penggalian yang paling tepat untuk diterapkan pada Kapal Keruk 21 Singkep 1 sesuai dengan lokasi kerjanya adalah sistem penggalian kombinasi yang memiliki tingkat keberhasilan aktivitas penambangan tertinggi dengan nilai Laju Pemindahan Tanah (LPT) ) yang dapat mancapai target senilai 592,78 m3/jam  dan kemiringan lereng (slope) akhir 45,83˚ yang sesuai dengan standar keamanan penambangan. Kata Kunci:  Kapal Keruk, Sistem Penggalian, Laju Pemindahan Tanah, Kemiringan Lereng,  ABSTRACT Mining using a dredger is an example of an aqueous open surface mining method. Due to its similarities of mining mechanism to a conventional open surface mining method, the difference being only the digging is carried out below the sea level (underwater) using a series of buckets. PT. Timah Tbk is a mining company that holds hundreds of mining concessions (Izin Usaha Pertambangan / IUP) for tin commodity and is the only company that owns several units of dredger, utilizing their fleet for mining operation of off-shore alluvial tin deposit in the waters of Bangka Island and Riau Archipelago. There are three known digging systems of dredger: vertical digging, benches and combination. These digging systems can affect the success of a dredger’s mining operation, which is assessed by following parameters: rate of material removal (Laju Pemindahan Tanah / LPT) and the inclination of slope formed by digging activities. The objective of this analysis on digging system is to find out which system should be applied depending on the dredger’s operational location. This analysis processes primary data obtained from digging activity of Kapal Keruk (dredger) 21 – Singkep 1 in May of 2019. The data consists of: ladder pressure, rate of ladder movement and pulling rate of wire. Thereafter, processing of data results in the value of rate of material removal and the slope inclination. Further analysis will disclose the benefits and also the shortcomings of each digging system. Based on acquired and processed data, the digging system that gives the highest rate of success of Kapal Keruk 21 – Singkep 1, which reflected on its rate of material removal of 592.78 m3/hour and final slope inclination of 45.83° (conform to the mining safety standard), is the combination system. Keywords: Dredger, Digging System, Rate of Material Removal, Slope Inclination

This study evaluated the influence of apical patency, root filling removal technique and cleaning of the apical foramen, concerning the amount of debris extruded during root canal retreatment. Forty mandibular incisors were randomly assigned to 4 groups - GIM (n=10), GIIM (n=10), GIPT (n=10) and GIIPT (n=10), which were named according to leaving (I) or not (II) apical patency during canal preparation and filling removal technique (manual - M or ProTaper system - PT). After filling material removal, each specimen of each group had the apical foramen cleaned by sizes 15, 20 and 25 instruments, generating 12 subgroups: GIM15, GIM20, GIM25, GIIM15, GIIM20, GIIM25, GIPT15, GIPT20, GIPT25, GIIPT15, GIIPT20 and GIIPT25. Extruded filling debris was collected by a Milipore filtration system, an HV-durapore, 0.45 µm pore filter with a 25 mm diameter. The filters were weighed before and after the collection on an analytical scale (10–5 g), and the difference was calculated. The mean weight of extruded filling debris was analyzed statistically by Kruskal-Wallis and Friedman ANOVA tests (α=0.05). The mean values found in the groups (in mg) were: GIM (0.95±0.94), GIIM (0.47±0.62), GIPT (0.30±0.31) and GIIPT (0.32±0.44). There was no statistically significant difference among any of the groups or subgroups (p>0.05). ProTaper provided the smallest amount of extruded filling material, regardless of presence or absence of apical patency, followed by manual technique, without and with apical patency. Additional amounts of debris were collected during cleaning of the apical foramen, regardless of the instrument, presence/absence of patency or root filling removal technique.

One of the chronicle problem in the disaster control of volcano eruption is the resettlement of relocated or transmigrated people to prohibitive region of the volcano. The more serious problem is happened when some of the labourers sand and stone mining living in those prohibitive region. Starting from those stated sttlement problem, this research aims at exposing the change, process, and continuity of setlement in the prohibitive region. This study employs so called sampling technique. Quota sampling is carried out according to village type. Two agricultural and mining village types in the prohibitive region are selected representing the sampling areas, encompassed administrative divisions of Srumbung subdistrict. The number of respondents are 60 households, selected unproportionally based on the village type. Primary data is collected diret communication with informants are key persons. Data analysis employs frequenccy and cross tabulation, and t test analysis. The study reveals that settlement changes in prohibitive region of Merapi vulcano has been fluctuatively recorded since 1006 based on the strength of Merapi vulcano eruption. However intensively settlement changes as an impact of the Merapi vulcano eruption have been recorded sine 1930 up to 1975 followed by more than 1742 people be dead as a victims and environment deterioration. The eruptions in 1954 and 1969 have resulted in drastically changes of physical and administrative condition village of Kaligesik and Gimal. At least 9 hamlets in both villages have been destroyed by ‘nue ardente’ and cold lava. Those eruptions have than change the administrative status of villages to be. Resettlement process within two hamlets in prohibitive region have taken place due to differences in origin area of the shelter, motivation to settle, and settlement pattern. Those two settle in mining villages are mining are mining labourer and mostly comes from outer subdistricts or districts, whereas those who stay in agriculture village are local people. The latter mostly joined transmigration program, which are supposed to stay in outer islands. A part from origin area, the difference of two settlers is also indicated by motivation. Economic motives are more dominant for those who settle in mining village than those who settle in agriculture village. The latter tend to have social motives to stay. The difference in settlement pattern between the vilages lays in ‘intermediary settlement’. This means that mining settlers have previously stayed in transmigration area. The duration to stay is between 15 to 20 years as compared to mining settlers whose duration to stay are between 5 to 10 years. Although the average household monthly inome in the respective two vilages is relatif the same (i.e. Rp 323,366 in Kaligesik and Rp 335,557 in Sumberejo), the physical condition of housing in Sumberejo look a little better than in Kaligesik. Despite the respective differences, people in the two villages tend to stay permanently. This means that the effort to vacant these prohibitive region will become more difficult.
