Abstract

Sistem hidrologi suatu daerah dipengaruhi oleh bentuk topografi permukaan yang merupakan daerah tangkapan air hujan. Air hujan yang mengalami infiltrasi ke dalam tanah menjadi aliran air tanah yang mempunyai pola hidrologi tertentu. Pemetaan hidrologi air tanah bawah permukaan telah dilakukan di Kawasan Ilo-Ilo desa Wori menggunakan metode geolistrik resistivitas konfigurasi wenner Alpha. Pengukuran dilakukan pada 4 lintasan dengan spasi elektroda 10 m, 48 elektroda dan panjang setiap lintasan 480 m. Daerah penelitian terbagi menjadi 2 pola sistem hidrologi yang terpisah yaitu hasil penelitian menunjukkan bahwa lintasan 3 merupakan area yang mempunyai akuifer paling besar dan permukaannya merupakan daerah tangkapan air. Air tanah cenderung mengalir ke arah lintasan 3, karena kondisi akuifer yang lebih dalam (> 60 m) pada kedua sistem hidrologiThe hydrological system of an area is affected by the shape of the surface topography which is a rainwater catchment area. Rainwater infiltrated into the soil becomes a groundwater flow that has a certain hydrological pattern. The mapping of subsurface hydrological groundwater in the Ilo-Ilo area of Wori village using the Wenner Alpha configuration of resistivity geoelecrical methods has been done. Measurements was made on 4 path with 10 m electrode spacing, 48 electrodes and length of each path is 480 m. The study area is divided into 2 separate hydrological system patterns. The result show us that path 3 is the area that has the largest aquifer and its surface is a water catchment area. Groundwater tends to flow toward path 3, due to deeper aquifer conditions (> 60 m) in both hydrological systems

Abstract

This study aims to find out the ecological characteristics of the soil in particular the physical, chemical and biological properties of the soil as indicators of the carrying capacity of tourism of Likri Island. Located on Likri Island, Tendengan Dua District Eris, Minahasa Regency. Using Laboratory Survey and Analysis Methods. Soil samples are taken at 6 points, at each point taken at a soil depth of 0-30 cm and 30-60 cm. Determination of sample points is carried out by purposive sampling. It then uses matching methods for land suitability analysis as an indicator of tourism carrying capacity. Based on the results of the research, the ecological characteristics of the soil on Likri Island, namely, it has a sandy soil texture with very fast permeability and the moisture content of the airy capacity ranges at an average value of 9.33% - 11.97% and the content of nutrients N, P, K and C-organic in moderate criteria. The suitability of Likri Island land for tourism activity is moderate (S) with limiting factors of soil texture and nutrient availability. Keywords:  Soil Ecology, Tourism Carrying Capacity, Likri Island Abstrak Penelitian ini bertujuan untuk mengetahui karakteristik ekologis tanah khususnya sifat fisik, kimia dan biologi tanah sebagai indikator daya dukung pariwisata Pulau Likri. Dilaksankana di Pulau Likri Desa Tendengan Dua Kecamatan Eris Kabupaten Minahasa. Menggunakan Metode Survey dan Analisis Laboratorim. Sampel tanah diambil pada 6 titik, disetiap titik diambil pada kedalaman tanah 0-30 cm dan 30-60 cm. Penentuan titik sampel dilakukan secara purposive sampling. Kemudian menggunakan metode matching untuk analisis kesesuaian lahan sebagai indikator daya dukung pariwisata. Berdasarkan hasil penelitian karakteristik ekologi tanah di Pulau Likri, yaitu memiliki tekstur tanah berpasir dengan permeablitas sangat cepat dan kadar air kapasitas lapang berkisar pada nilai rata-rata 9,33% - 11,97% dan kandungan unsur hara N, P, K dan C-organik dalam kriteria sedang. Kesesuaian lahan Pulau Likri untuk aktivitas pariwisata adalah sedang (S) dengan faktor pembatas tekstur tanah dan ketersedian hara. Kata Kunci : Ekologi Tanah, Daya Dukung Pariwisata, Pulau Likri

Abstract

EMPAT SAUDARA is a company engagedin manufacturing by producing refined salt. A tany time the production process on the machine certainly haspotential hazards that must be avoided by workers. In addition to the danger sposed by machines, there a real sohazard factors caused by the workers them selves, human error factors or Human Error. This study aimsto "how touse the SHERPA method in evaluating human error so that preventive step scan be determined". For the prevention of human error usedin this study using the SHERPA method (Systematic Human Error Reduction and Prediction Approach) which aimsto determine the potential forwork accidents that mayoccuror determine the application of preventionas early as possible. There sults of this study using the SHERPA method obtained 1 HTA diagrams of the salt making process with a total of 22 tasks consisting of material and machine in spection, material arrival, processing process and distribution process. An error correction strategy was produced as a proposal consisting of tighter supervision, training for employees, the use of safety shoes back support belts and the use of correct lifting techniques. Keywords: SHERPA Method, human error, PT Empat Saudara ABSTRAK EMPAT SAUDARA merupakan perusahaan yang bergerak dalam bidang manufaktur dengan memproduksi garam halus. Setiap saat proses produksi pada mesin pastinya memiliki potensi bahaya yang harus dihindari para pekerja. Selain bahaya yang ditimbulkan oleh mesin, ada juga factor bahaya yang ditimbulkan oleh pekerja itu sendiri, factor kesalahan manusia atau Human Error. Penelitian ini bertujuan bagaimana dapat menggunakan metode SHERPA dalam mengevaluasi human error sehingga dapat ditentukan langkah pencegahannya”. Untuk pencegahan human error yang digunakan dalam penelitian ini menggunakan metode SHERPA (Systematic Human Error Reduction and Prediction Approach) yang bertujuan untuk mengetahui potensi kecelakaan kerja yang kemungkinan terjadi ataupun menentukan penerapan pencegahan sedini mungkin. Hasil penelitian ini dengan menggunakan metode SHERPA diperoleh 1 Diagram HTA proses pembuatan garam dengan total task 22 yang terdiri dari pemeriksaan bahan dan mesin, kedatangan bahan, proses pengolahan dan proses pendistribusian. Dihasilkan strategi perbaikan error sebagai usulan yang terdiri dari pengawasan yang lebih ketat, melakukan pelatihan bagi karyawan, penggunaan safety shoes, back support belt, melakukan breafing serta penggunaan teknik mengangkat dengan benar.

Abstract

Province of North Sulawesi has been known as wave palm area (coconut). One of the plantations (coconut) potential become the farmer&rsquo;s income and Locally-Generated Revenue (LGR). Therefore, it is important to maximize the soil function and root system of coconut. This research was aimed to diagnose a soil and coconut root existence in Lontang Plantation of Manado City. Soil observations were carried out on a single stretch of coconut plantations owned by community. The observation was done through the soil profile at a spacing of <1 m; 3 m and 5 m from the main tree of the coconut. The results showed that decreasing of C-Organic content in 1 m depth was not followed by enhancement of soil content weight, because C-Organic has spread equally in middle state and into the depth of >1 m on 3 and 5 m spacing profile from the main tree which categorized as low. Existence of total root length (Lrv) and dry root weight (Drv) shows that deeper soil will be more reduced of the root Lrv and Drv values along with the organic material in the bottom layer (> 1 m) lower than above it. The highest Lrv and Drv average value is located on the depth of 0 &ndash; 60 cm. Specrol existence on 1 - 3 m spacing profile have showed many soft roots which grow on these spacing. The soft root has a roles to absorb nutrient and water for the plant and direct contact with the soil.
