Abstract

Kelurahan Pedalangan secara administratif berbatasan dengan Kelurahan Tembalang, Kelurahan Kramas, Kelurahan Padangsari, dan Kelurahan Srondol Wetan. Akibat adanya kawasan pendidikan di Kelurahan Tembalang, maka berdampak pula pada perkembangan wilayah di Kelurahan Pedalangan, baik dari segi perubahan lahan maupun pertumbuhan penduduk. Seiring dengan pertumbuhan penduduk yang pesat di Kelurahan Pedalangan maka harus diimbangi dengan peningkatan fasilitas umum di wilayah tersebut, Untuk memberikan fasilitas umum yang cukup bagi masyarakat di Kelurahan Pedalangan maka diperlukan peningkatan fasilitas ibadah, salah satu fasilitas ibadah yang perlu ditingkatkan khususnya pada wilayah RT/RW 03/03 Kelurahan Pedalangan adalah masjid. Alternatif yang di rencanakan oleh warga sekitar adalah pembangunan masjid baru akan tetapi, yang menjadi kendala adalah kurangnya pengetahuan warga masyarakat tentang peraturan pemerintah untuk mendirikan bangunan dimana lahan yang ada terdapat sumber air/Sendang. Untuk mengatasi hal tersebut, maka dilakukan inventarisasi kondisi lahan dan kebutuhan luas bangunan yang diperlukan.Target yang ingin dicapai dari kegiatan ini adalah memperiapkan Perencanaan Tampak bangunan dan anggaran yang diperlukan agar dapat dipersiapkan dan dicari sumber pendanaan dengan rembug warga masyarakat di Kelurahan Pedalangan khususnya masyarakat sekitar lokasi tentang Pembanguanan Masjid sebagai perkiraan dalam pelaksanaan pembangunan. Metode kegiatan yang direncanakan dimulai dengan diskusi dan musyawarah warga sosialisasi atau penyampaian hasil perhitungan desain struktur dan perencanaan rencana anggaran biaya. Sehingga diharapkan melalui kegiatan ini mampu memberikan manfaat bagi tim pengabdian masyarakat Polines (dosen) maupun bagi masyarakat sekitar.

Abstract

Pemanfaatan material alternatif sebagai pengganti semen merupakan salah satu upaya meningkatakan nilai jual material alternatif tersebut, selain itu juga dapat mengurangi penggunaan material yang tidak ramah lingkungan dalam dunia konstruksi. Laporan dari BBC mengutip dari Chatham House menyebutkan semen adalah sumber sekitar 8% dari emisi karbon dioksida (CO2) dunia. Penelitian ini merupakan kelanjutan dari penelitian sebelumnya tentang mortar. Wahjoedi et.al, 2021 telah melakukan penelitian penggunaan tras sebagai bahan substitusi terhadap semen portland dalam pembuatan mortar. Campuran dibuat tanpa dan mengganti komposisi semen dengan tras dan kapur pada proporsi tertentu, akan diperoleh adukan konsistensi normal dari kadar masing-masing bahan (air, semen, agregat halus, tras dan kapur) dan selanjutnya diuji kuat tekannya melalui benda uji kubus ukuran 5 cm x 5 cm x 5 cm pada 28 hari. Dari hasil penelitian diperoleh nilai kuat tekan mortar hasil substitusi semen portland menggunakan tras dan kapur sebagai berikut: 1) substitusi 0% menghasilkan kuat tekan mortar 30,20 MPa; 2) substitusi 10% (5% tras dan 5% kapur) menghasilkan kuat tekan mortar 21,62 MPa; 3) substitusi 15% (7,5% tras dan 7,5% kapur) menghasilkan kuat tekan mortar 21,02 MPa; 4) substitusi 20% (10% tras dan 10% kapur) menghasilkan kuat tekan mortar 16,28 MPa; 5) substitusi 25% (12,5% tras dan 12,5% kapur) menghasilkan kuat tekan mortar 12,98 MPa. Sehingga dari penelitian tersebut dapat disimpulkan bahwa penggunaan tras sebagai bahan substitusi semen portland dapat memenuhi kriteria Mortar tipe M (kuat tekan 17,2 MPa) secara optimal pada persentase tras hingga sebesar 15%.

Abstract

Waste is the remains of daily human activities and/or from natural processes in solid form, and the source of waste is the initial/first place where the waste is. Based on the chemical properties of waste it is grouped into two types, namely organic waste which consists of organic compounds (carbon, hydrogen, oxygen and nitrogen and are quickly decomposed/weathered) come from living/dead things. The second type is inorganic waste which consists of non-organic materials (difficult to be decomposed by soil microorganisms) so it is durable and does not decompose easily. This article contains a report on the implementation of community service regarding the application of technology in managing household waste sorting on Jalan Bukit Cemara Indah XI RT 06 RW 13 Meteseh Village, Tembalang District, Semarang City. The aim of this service is to provide guidance by means of mentoring and counseling in managing waste sorting in the community. The method used consists of three stages which include (1) the observation and needs analysis preparation stage, (2) the implementation of the service process, (3) the service finalization and evaluation stage. The result of this service is the implementation of assistance in waste sorting management which is supported by the construction of a waste sorting place for the community on Jalan Bukit Cemara Indah XI RT 06 RW 13, Meteseh Village, Tembalang District, Semarang City.

Abstract

Vehicles that park on the road cause traffic jams and obstruct traffic flow as well as reducing the level of road service. The ability of a road to provide good and maximum traffic services is closely related to the capacity of the road section. Apart from road capacity, the performance of a road is also closely related to traffic performance. This method is used to analyze the condition of road sections. In the results of road performance analysis by calculating the level of road service, the V/C Ratio value is obtained which will indicate the level of service. Research in a traffic flow movement on a highway there are three main variables used to describe the characteristics of traffic flow , namely speed, volume and density. On the Jl. Sipodang has a capacity of 1638,291 pcu/hour and the average volume on this road is 741.79 pcu/hour, and has a degree of saturation of 0.45 where this figure is in service level C with the characteristics of stable flow, but speed and vehicle motion is controlled, the driver is limited in choosing speed. On the Jl. Gondang Raya has a capacity of 1486,285 pcu/hour and the average volume on this road is 1535.2 pcu/hour, and has a degree of saturation of 1.03 where this figure is at service level E with characteristics of obstructed flow, low speed, volume above capacity, traffic jams often occur for quite a long time. On the Jl. Soeparto from the west has a capacity of 2925.52 pcu/hour and the average volume on this road is 1697.09 pcu/hour, and has a degree of saturation of 0.58 where this figure is at service level C with the characteristics of stable flow, but the speed and motion of the vehicle are controlled, the driver is limited in choosing the speed. On the Jl. Soeparto from the west has a capacity of 2925.52 pcu/hour and the average volume on this road is 1506,171 pcu/hour, and has a degree of saturation of 0.51 where this figure is at service level C with characteristics of stable flow. , but the speed and motion of the vehicle are controlled, the driver is limited in choosing the speed.

Abstract

Activities that occur in an activity center will certainly cause vehicle parking activities. Parking facilities are a very important supporting factor and require extra attention for their development in the activity center. Parking problems are something that we often encounter in various locations of educational centers, shopping centers, hospitals, factories, universities and many other places. One real example that occurs in Semarang is on the Semarang State Polytechnic campus, every day active lectures are certainly always a buildup of vehicles that cause traffic activities around the Semarang State Polytechnic campus to become dense. Therefore, an evaluation is needed to fulfill the need for parking space on the Semarang State Polytechnic campus. In evaluating the fulfillment of parking needs, Parking Characteristics on the Semarang State Polytechnic Campus with a composition of 2-wheeled and 4-wheeled vehicles with a parking duration for each type of vehicle is 425 minutes and 546 minutes with a parking index of 104% and 277%. The need for parking space that must be provided on the Semarang State Polytechnic campus with each type of vehicle is 3622.3 for 2-wheeled vehicles and 140.8 for 4-wheeled vehicles.

Abstract

Urban farming is an effort to maintain resilience in the capital city of Central Java. The Semarang City Government continues to be committed to improving the quality of regional development with benchmarks from aspects of development achievement, quality aspects, document preparation aspects, and innovation aspects. In 2023, the Semarang City Government will carry out program innovations such as the Food Startup Challenge, Urban farming Corner, Rumah Gizi Pelangi Nusantara, and Sekolah Berkebun which will be included in the assessment of the Regional Development Awards (PPD) for Regency/City at the Central Java Province level. In carrying out this innovation, the Semarang City Government also encourages the involvement of all levels of society, especially women's groups and children through the curriculum in schools. This urban farming can support nutritional improvements for stunted children in the City of Semarang. As is known, the City of Semarang has succeeded in scoring a hat trick as the first best city in the Regional Development Awards or PPD for 3 consecutive years (2019, 2020, 2021) both at the Central Java Province and national levels. One of the activities that can support the urban farming program is the availability of green houses for plant nurseries in the RT, RW, and sub-district sectors. The construction of green houses for nurseries is very important for the community, especially residents of RT 06, Meteseh Village, so that they can produce plant seeds independently and can carry out planting activities or movements carried out by the Semarang city government
