Abstract

Gondanglegi Kulon Village is located in Gondanglegi District, Malang Regency, the research location is in the Muhammadiyah Entrepreneur Islamic Boarding School area. From the results of information from local villagers, it was explained that in the study area there was no shallow groundwater found. This is also reinforced by the fact that there are no wells in the settlements of the residents around the Entrepreneur Muhammadiyah Islamic Boarding School, so that practically no residents use wells to fulfill clean water, they still depend on river water or PDAM services which are relatively expensive and continuous. still below expectations. As a center for religious education, Islamic boarding schools continue to develop supporting facilities. One of the most needed facilities is the availability of clean water. Quantitatively, the supply from the PDAM is not sufficient and the operational costs borne by the manager are too high. The use of groundwater is a solution that can be used to meet the needs of clean water at the research location. Therefore we need a technology to identify the point of exploration, the technology used in this research is geoelectric resistivity. By using the resistivity geoelectric method, it is expected to know the rock structure at the research location and see the potential for deep groundwater. Thus, the hope that in the future the Entrepreneur Muhammadiyah Islamic Boarding School (PPEM) will no longer depend on water raw materials from the PDAM, so the hope is that daily operational costs related to clean water needs can be minimized. From the results of the analysis and discussion, 2 (two) points of drilling recommendations were obtained, but with technical and non-technical considerations, exploration was suggested at point 3 with a potential of 4.2423 L / sec. Where at this location is a rock lithological arrangement consisting of a top soil layer, a clay layer, a tuff layer, a sandy silt layer, a sand layer and a gravel layer.

Abstract

Modern Islamic boarding schools are a combination of Islamic boarding school curriculum with the national education curriculum. Therefore though the format is a boarding school, boarding education, students also acquire knowledge and graduation standards as students who attend public schools. The Entrepreneur Muhammadiyah Islamic Boarding School (PPEM) is a charity business unit managed by the Muhammadiyah Branch Leader (PCM) Gondanglegi, Malang Regency. The land used by the lodge is certified charity land. Along with the construction of housing on the side of cottage land, land boundaries have become a new problem between the border of cottage and housing developers. There is a difference in stake and land boundary, claimed by the housing developer next to the cottage. The target and output of this service program are that PPEM administrators can make an inventory of land through physical mapping. The product of this activity is the result of land mapping, which is applied directly in the form of a topographical mockup of the Islamic boarding school land that follows the mapping results and strengthens the land certificate.ABSTRAKSistem pondok pesantren yang modern adalah perpaduan antara kurikulum pendidikan nasional dengan kurikulum pesantren, sehingga walaupun bentuknya adalah sebuah pondok pesantren, santri juga memperoleh ilmu dan standar kelulusan seperti pelajar sekolah pada sekolah umum. Pondok Pesantren Entrepreneur Muhammadiyah (PPEM) adalah salah satu unit amal usaha di bawah pengelolaan Pimpinan Cabang Muhammadiyah (PCM) Gondanglegi, Kabupaten Malang. Lahan yang digunakan oleh pondok merupakan lahan wakaf bersertifikat. Seiring dengan pembangunan perumahan di sisi lahan pondok, batas lahan menjadi satu masalah baru, antara pengurus pondok, dengan pihak pengembang perumahan.

Abstract

An intersection is a part of a road where currents from various directions or directions meet. This is what causes conflicts between currents from opposite directions and intersect each other, resulting in congestion along the intersection arm. The signalized intersection on Jl. Panglima Sudirman – Jl. Urip Sumoharjo – Jl. Pattimura is one of the main network junctions in Malang City, precisely located in an area that provides several public facilities, namely the National Defense Field, Kota Baru Station and Klojen Market. This intersection connects to public places such as the city center, schools, offices and others. This reseach aims to evaluate the performance of the intersection and the degree of saturation as well as the level of service at the signalized intersection at the current condition based on the Indonesian Road Capacity Manual (MKJI) 1997. This reseach uses empirical methods to obtain data from observations that occur in the field. From the results of the reseach the degree of saturation (DS) on the north approach was 0.89, with queue length (QL) = 140.30 m, south approach 0.84, with queue length (QL) = 97.25 m, east approach 0, 49 with queue length (QL) = 69.25 m and the western approach 0.56 with queue length (QL) = 54.40 m. The average delay of the intersection is 27.31 sec/pcu and is included in the value of service level of service D.

Abstract

Highways are transportation infrastructure that is very important in supporting land transportation. Without being matched by an increase in road infrastructure, it will result in an excessive load on the road structure and will cause congestion. Congestion is one of the problems that is often experienced or encountered, congestion occurs due to the large number of vehicles that exceed the capacity of the road so that it affects road performance. Based on the network pattern seen during holidays or weekends, access to and from the Malang City area tends to increase. Road side barriers that occur on Commander Sudirman street, Singosari are one of the causes of traffic jams. This research aims to provide an alternative plan in overcoming the problem of traffic jams on Commander Sudirman street, Singosari. The method used in this research was based on the 1997 Indonesian Highway Capacity Manual (MKJI), as well as data collection using direct observation methods in the field and then followed by collecting primary data and secondary data. From the research results, the vehicle volume of 2320.6 pcu/hour and degree of saturation (DS) of 0.80 with a level of service (LOS) class D. So it is necessary to divert the route for heavy vehicles (HV) that pass through Commander Sudirman street in the direction of Malang - Surabaya to be diverted via Tumapel street, Ronggowuni street and Kertanegara street, then return to street main route, while for vehicles from Surabaya to Malang that will cross Commander Sudirman street with heavy vehicle types (HV) will follow the current road diversion, namely crossing Rogonoto street, Kebon Agung street, Watu Gede street, and Stasiun street then returning. to the main road as well as installing signs prohibiting parking in the Singosari market shopping area which is on Commander Sudirman street. From the results of this treatment the DS value became 0.76.

Abstract

Pembangkit Listrik Tenaga Mikro Hidro adalah pembangkit listrik skala kecil yang menggunakan tenaga air di bawah kapasitas 1 MW yang dapat berasal dari jaringan irigasi, sungai, dan air terjun, dengan cara memanfaatkan tinggi terjunnya dan jumlah debit air. Kabupaten Malang mempunyai potensi besar bagi pengembangan PLTMH. Hingga saat ini saluran irigasi atau sumber air yang berpotensi sebagai sumber energi baru sangat sedikit yang memanfaatkan. Ketersediaan air dan tinggi jatuh pada saluran irigasi dan pembuangan di daerah studi merupakan faktor utama potensi pembangunan PLTMH. Pembangunan PLTMH di desa Gondanglegi dapat digunakan sebagai penerangan jalan yang saat ini masih kurang atau dapat digunakan sebagai tempat pembelajaran tentang PLTMH bagi warga sekitar dan SMK Mutu ataupun Pondok Pesantren Entrepreneur Muhammadiyah (PPEM). Dengan adanya potensi sumber daya serupa yang ada maka dapat juga dilakukan identifikasi dan inventarisasi hingga perencanaan pembangunan PLTMH di aliran irigasi sebelah PPEM. Berdasarkan observasi dan pengukuran awal, debit air sesaat di lokasi Gondanglegi sebesar 3,5 m3/dtk dan akan digunakan pada tiap turbin untuk desain debit pembangkit sebesar 1,75 m3/dtk, potensi tinggi jatuh hidrolik total sebesar2,00 m. Sehingga, potensi daya yang dapat dipasang sebesar 49,44 KWh.Kata kunci: Tinggi Jatuh, Debit, PLTMH, Pembangkit

Abstract

Kegiatan ini menindaklanjuti saran pada kegiatan pengabdian sebelumnya, yakni terkait peningkatan peran serta masyarakat dalam pencegahan COVID-19 di RW VII Kelurahan Purwantoro Kota Malang. Atas keberhasilan dan respon positif dari warga, maka muncul usulan permintaan dari warga untuk dapat membantu mendampingi rencana kegiatan peningkatan fasilitas umum yang ada. Dari hasil musyawarah warga yang sebagian besar juga merupakan jamaah Musholla Nawawiyah. Kegiatan yang perlu dilakukan adalah suatu kegiatan yang berkaitan dengan pendampingan rencana revitalisasi pada musholla tersebut. Metode yang digunakan dalam kegiatan pengabdian ini serta sekaligus merupakan penerapan mata kuliah dalam dunia nyata terhadap komunitas atau masyarakat adalah metode yang disebut dengan Service Learning (SL). Mengingat dalam rangka memajukan ukhuwah islamiyah di lingkungan warga ciliwung gang 1, maka warga berharap ada bantuan pendampingan dari Tim Pengabdian untuk bisa memberikan arahan perbaikan ringan. Mengingat Musholla Nawawiyah merupakan satu-satunya tempat ibadah milik umum yang ada di wilayah RT 02 RW VII. Kegiatan yang saat ini menjadi lokus takmir musholla adalah perbaikan atap dan kubah, serta pengajuan sertifikasi arah kiblat. Metode yang digunakan tim adalah pengukuran langsung dan penghitungan analisis biaya yang dibutuhkan berdasarkan ketentuan harga satuan Kota Malang. Dari keseluruhan kegiatan yang telah dilakukan tim, Alhamdulillah telah didapatkan sertifikat arah kiblat dari Kantor Kementerian Agama setempat, gambar rencana atap dan kubah, serta estimasi biaya yang dibutuhkan sebesar Rp. 55.700.231.58,-
