Leyangan Village is one of the villages in Central Java located in Penawangan District, Grobogan Regency, and Central Java Province. The location of the village is ±50.1 km from the Semarang University (USM) campus. Understanding and implementing SOPs for maintaining wastewater treatment plant structures is one of the problems Leyangan village residents face when they receive assistance in the form of domestic wastewater treatment installation facilities. This activity aims to increase the knowledge of the Leyangan village community regarding methods for maintaining wastewater treatment plant (IPAL) structures. It is necessary to provide explanations and assistance regarding the Leyangan Village wastewater treatment plant which can still function effectively and well and encourage the community to adopt clean and healthy living habits. Assistance is carried out by providing presentations, demonstrations, and direct practice regarding the maintenance of wastewater treatment plants. The result of the training activity is an increase in knowledge. Evaluation is carried out by looking at the results of the pre-test questionnaire and comparing it with the post-test questionnaire. At the beginning before training, the average level of knowledge of participants only reached 32%. However, after training and direct practice were carried out, the participants' knowledge increased to an average of 70%.

Paper ini menyajikan hasil penilaian terhadap gedung bertingkat eksisting 8 tingkat, yang bertujuan untuk mengetahui tingkat keamanannya terhadap standar yang terbaru. Metode yang digunakan adalah pengujian tidak merusak pada beton dengan Rebound Hammer. Penilaian struktur eksisting terdiri dari evaluasi terhadap kondisi material, sistim struktur, dan analisis struktur menggunakan standar beban yang terbaru. Hasil pengujian material struktur eksisting menunjukkan bahwa kuat tekan beton masih memenuhi persyaratan berdasarkan SNI-2847-2019. Hasil evaluasi struktur terhadap beban gempa menunjukkan bahwa kinerja struktur mempunyai gaya geser dasar dinamik (V) mencapai 100% dari Vstatik sehingga sudah memenuhi persyaratan dalam SNI 1726-2019. Hasil evaluasi terhadap kinerja struktur menunjukkan bahwa lateral drift dan efek P-delta masih memenuhi persyaratan standar terbaru. Ketidakterarturan struktur horizontal pada sistem struktur gedung eksisting. level kinerja struktur menunjukkan struktur termasuk kategori   Immediate Occupancy.

<p><em>I</em><em>n building infrastructure, cost calculations are needed, organized in the form of a Budget Plan (RAB) according to government standards. The RAB provides an overview of the total cost required for building infrastructure or construction projects. Additionally, the RAB calculations can also determine the need for building materials, the number of workers required, and the duration of the project. This Community Service program aims to provide knowledge and new skills to the community on how to calculate the Budget Plan (RAB) for building both private homes and community infrastructure, such as meeting halls, neighborhood watch posts, water channels, and so on. The implementation method begins with interviews to assess understanding of creating an RAB, followed by socializing the benefits of making an RAB, training, and practical exercises on how to calculate the RAB. Subsequent steps include monitoring and evaluating the results of the calculations. This Community Service program equips the community with the skills to calculate the RAB for infrastructure development, better understand the volume of work calculations, determine material prices or unit prices for work, and prevent cost overruns during the construction phase.</em></p>

<p>Permasalahan yang berkaitan erat dengan transportasi adalah pertumbuhan penduduk yang selalu mengalami peningkatan setiap tahunnya. Hal tersebut mengakibatkan kegiatan dan mobilisasi penduduk menjadi semakin tinggi dan cepat. Penggunaan ruang jalan yang tidak sebagai mana mestinya dapat menurunkan tingkat pelayanan jalan sehingga terjadi kemacetan. Volume lalulintas pada jam sibuk dalam satu hari digunakan sebagai dasar untuk menganalisa kinerja ruas jalan dan persimpangan yang ada. Penyebab kepadatan lalu lintas pada Jalan Raya Mranggen yaitu pertama nilai (Q) arus lalu lintas menunjukan nilai tinggi yaitu sebesar 2388 smp/jam. Yang kedua nilai hambatan samping yaitu sebesar 849,8. Yang ketiga nilai (C) kapasitas jalan tinggi dan mendekati padat sehingga tidak mampu menampung volume lalulintas yaitu senilai 2697 smp/jam. Yang ke empat yaitu angka (DS) derajat kejenuhan sebesar 0,88 yang mendekati nilai jenuh yaitu 1, sehingga nilai tersebut tidak memenuhi kondisi yang seharusnya. Alternatif yang diusulkan adalah dengan upaya menambah kapasitas jalan dengan lebar 11m dan mengurangi kemacetan yang terjadi akibat mobil parkir di pinggir jalan. Alternatif tersebut memiliki nilai (C) kapasitas sebesar 3886 smp/jam, (Q) arus lalulintas sebesar 2388 smp/jam, sehingga (DS) derajat kejenuhan menjadi 0,61.</p><input id="ext" type="hidden" value="1" />
