The research was conducted to : (1) Knowing how the process of making coconut shell fly ash in concrete mixtures, (2) Knowing how the effect of increasing coconut shell fly ash to the compressive strength of concrete. The researcher was used experiment method. There are three samples of experiment things that used to increase the percentage of coconut shell fly ash. The size of the cylindrical mold was 15 cm and the height diameters were 30 cm. The treatment was passing for 7 days, the value of strong pressure was correlated over 28 days. The finding research was found that the compound of coconut shell fly ash for quality concrete K-100 which affects the compressive strength of the concrete itself. From the data, it has been carried out that in this research coconut shell fly ash has increased significantly, the highest concrete coconut shell fly ash mixture 1.5% can reach a compressive strength of 31,643 MPa. At last, it can be concluded that coconut shell fly ash can be used as an added material for cement in K-100 quality concrete in the presentation above. For the next research, the researcher should do the deepest experiences to know the strength of concrete. Keywords : Concrete, Compressive Strength, Coconut Shell Fly.

Kabupaten lamongan merupakan kabupaten yang memiliki berbagai macam potensi. Termasuk potensi wisata di kabupaten lamongan juga tidak kalah dengan daerah lain di jawa timur. Makam Mbah Anggungboyo, orang-orang disana menyebut makam itu adalah makam JokoTingkir. Sebuah makam keramat yang terkadang dikunjungi banyak penziarah dari luar desa bahkan luar kota Dari hal tersebut penulis mempunyai ide untuk mengembangkan potensi yang ada di Dusun Dukoh Desa Pringgoboyo Kec. Maduran Kab. Lamongan melalui Program Pengabdian Masyarakat ini. Tujuan Penelitian hendak dicapai dalam program ini yaitu Terwujudnya Perencanaan Desa Wisata Berbasis Wisata Religi Makam Joko Tingkir Dusun Dukoh Desa Pringgoboyo Kec. Maduran Kab. Lamongan. Metode yang digunakan dalam penelitian ini adalah survey lahan area makam dengan mengidentifikasi data ukuran dan batas batas wilayah makam. Setelah itu dilanjut dengan merencanakan denah dan model bangunan yang akan dijadikan desa wisata berbasis wisata religi. Dari hasil penelitian yang dilakukan dan pembahasan Perencanaan Pengembangan Desa Wisata Makam Joko Tingkir Berbasis Wisata Religi Desa Pringgoboyo Kabupaten Lamongan simpulkan bahwa perencanaan ini memerlukan luas area sebesar 46.816 m2. Dari luas tersebut memiliki beberapa analisa yaitu Analisis Tapak,Tujuan Analisis Tapak, Proses Analisa Tapak dan Design, Zoning Massa Solid Dan Void, Jalur Sirkulasi. Bangunan yang direncanakan meliputi Pendopo Makam, Museum dan mini teater, pujasera, parkir mobil dan motor, gapura pintu utama.

Road damage in Bulutigo Village, Laren District, Lamongan Regency affects access to agricultural mobilization in Lamongan Regency. So the researchers studied the value of the carrying capacity of the soil that caused road damage on the Bulutigo Village road, Laren District, Lamongan Regency. This study also examines the factors that affect the decline in the value of the bearing capacity of the soil. Data processing shows that the road subgrade soil in Bulutigo Village, Laren District, Lamongan Regency has a low carrying capacity value in terms of water content testing with an average value of 16.66% which includes high water content, from the Atterberg limit, it is included in the class of clay soil type. has a high plastic value with a PI value of 34.61%. Meanwhile, in the CBR test, the CBR value was 6.80% which was included in the "enough" category. And in the direct shear strength test, the value of the internal shear angle () is 15.03o.

The purpose of this study was to determine whether the roots of bamboo fiber can be mixed with asphalt which is adhesive (waterproof) and an alternative to overcome the problem of road damage. The process of mixing bamboo root fiber with AC-WC asphalt is carried out during the frying process with the aggregate, then after the frying process is carried out the pounding process is carried out (compact), then let stand and after cooling the mashall test process is carried out. Effect of the 3 variations used, namely 0%, 3%, and 5% addition of bamboo fiber roots used did not meet the standard specification of Bina Marga V 2002. 0% was the Marshall Stability value of 898,587kg, FLOW with a value of 2.0 mm, 3 % is with the value of Marshall Stability 592,320kg, FLOW with a value of 2.8 mm, 5% is with a value of Marshall Stability 527,110, FLOW with a value of 4.9 mm.

Reservoir is a container or place for storing raw water, which will later be used as a temporary water storage area, then used as a place for water treatment for the continued growth of rice plants. In addition to rice plants, reservoirs are also used to minimize drought disasters in the dry season. The construction of this reservoir will be used by the Kramat village community to improve the economy in two sectors, namely agriculture and village potential, Kramat village itself is one of the villages in Lamongan Regency which has an area of 194.80 hectares and is located in Lamongan sub-district which has a population of 2,012 people. Most of their livelihoods are farmers. Seeing such conditions, farmers need facilities to help meet the needs of raw water for their agricultural land which will be planned with the planning method carried out by the construction of the reservoir with various stages such as measuring with 2 methods, either surveying in the field or utilizing digital applications or software using fields area or Google earth, after finding the size, then we can determine the sketch of the image on the reservoir by drawing in AutoCAD software. The area of land used for the construction of the reservoir has an area of 1,452.03 m2, which is later estimated to be able to accommodate 8,507,190 L of water. The total volume of excavation work is 8,507.19 m3 with an estimated work period of 23 days. Excavator pc 200 heavy equipment operational cost : Rp. 101.200.000 per 23 days and for Dump truck capacity of 8 m3: Rp. 2,400,000 (2 dump trucks) per day.

Concrete quality depends on the value of the ratio of materials, how to blend and how to pour the concrete mixture, how to compact and how to care for it during the hardening process. This study aims to determine how much influence the curing process using water with a mixture of Co(NH2)2 and normal water has on the compressive strength of concrete fc' 20 Mpa. The sample is a cylindrical specimen with a diameter of 15 cm and a height of 30 cm. Samples were made 3 test objects with the age of 28 days and tested coherently. The compressive strength of normal concrete has increased in quality with the age between 7 is 9.1 Mpa to 28 days is 17 Mpa. While the concrete with curring process using water with a mixture of urea increased at age 7 with a value of 10.8 Mpa to 21 days with a value of 14.4 Mpa, but at age 28 the strength of the concrete decreased by 12 Mpa. Cracks with cone and split types are 10 pieces, this can happen because the material in the concrete mixer has not been mixed well during the concrete manufacturing process.
