Abstract

The high mobility of the people and traffic due to the existence of a railroad crossing on the Mranggen road section is the main factor for the high congestion that exists on this section. The government's efforts through the Central Java Office of Public Works and Human Settlements to build the Ganefo Mranggen KM 14 Fly Over is an alternative solution to tackling the high traffic jams on this section. Therefore, researchers will identify how the performance of the Mranggen road section after the construction of the Fly Over. After conducting research, it was found that the busiest traffic was on Wednesday at 16.00-16.15 with a total flow value of 883.3 pcu/hour. The degree of saturation is 0.962 0.75, which exceeds the requirements of the 1997 MKJI guidelines. If the value of the degree of saturation 0.75 requires improvement, then the degree of saturation is included in the category E service level with conditions of very high traffic density and low volume. The highest side resistance value on this section is 906.8 where the time interval is 06.00-09.00 WIB with the VH Resistance Class (906.8 900) which means commercial area, with roadside market activity. So that alternative solutions can be found using SWOT calculations where it is known that the segment is in a position between the Weakness and Opportunity axes, namely in quadrant 4. This means that the Ganefo Mranggen Fly Over segment is advised to change the strategy from internal Weaknesses So that the strategy is changed to Opportunity ( external Opportunity) in order to achieve good traffic performance on the Ganefo Mranggen Km 14 Fly Over section.

Abstract

The tempe industry is a food industry that has the potential to pollute the environment from the liquid waste it produces. Liquid waste from the tempe processing process if it is immediately disposed of without going through the management process first will have an impact on environmental pollution. In Semarang City, precisely in Gunung Pati District, there is a medium-scale tempe processing factory. So far, the tempe factory's liquid waste is directly disposed of into a ditch behind the factory without processing the liquid waste first.This research is a quantitative research presented in the form of numbers and then explained in the form of descriptions. From the results of the wastewater quality test, the pollutant parameters BOD = 369 mg/L; COD = 28,000 mg/L; TSS = 0.991 mg/L; and pH = 4,3. According to the Regional Regulation of the Province of Central Java Number 5 of 2012 concerning Amendments to the Regional Regulation of the Province of Central Java Number 10 of 2004 this value still does not meet the requirements. The wastewater treatment plant that the researchers are planning is in the form of a holding tank; Equalization Tub; Anaerobic Digesters; Gas Holder; Initial Settling Tub; Anaerobic Biofilter using bioball filter media and steel nets as a barrier for bioballs where bacteria are grown; and Final Settling Tank. With an estimated effluent from the processing of BOD, COD, and TSS of 7.47225 mg/L; 189mg/L; and 0.00669 mg/L which means it meets the quality standard. From the planning results, it was obtained that the total budget plan for planning the tempe factory wastewater treatment plant was Rp. 111.280.021,49.

Abstract

In the production process, the tofu industry produces solid and liquid waste. The waste contains organic matter with high levels of BOD, COD, and TSS and does not meet quality standards. If the waste is directly discharged into the environment, it will reduce the carrying capacity of the environment. This research was conducted at the WD Lamper Lor Tofu Factory, with the aim of planning the design and RAB for the construction of the wastewater treatment plant at the Tofu Factory. This research uses quantitative analysis methods which are presented in the form of numbers which are then explained and interpreted in the form of descriptions. The quality of BOD, COD, TSS, and pH were 144 mg/L, respectively; 380 mg/L; 98 mg/L; and 4.34. Based on the quality standards, the wastewater does not meet the requirements, so it is necessary to plan a wastewater treatment plant. Researchers plan the processing stages, namely Reservoir, Equalization, Anaerobic Digester, Gas Storage, Presettlement Tub, Anaerobic Biofilter, and Final Sedimentation Tub. The estimated effluent from the processing of BOD, COD, and TSS is 2,916 mg/L, respectively; 7.695 mg/L; 2.116 mg/L. In addition to processing it into water that is fit for reuse, the design of this wastewater treatment plant produces methane gas that can be used for the tofu-making process or can be used on a household scale. The total budget plan for the planning of the Wastewater Treatment Plant at the WD Tofu Factory is 31,106,117.05.

Abstract

The soil condition in Sigar Bencah, Semarang City, has characteristics that are less supportive of construction, such as cracks, low bearing capacity, and instability. This study aims to evaluate the effects of soil stabilization using lime and cement on soil compaction and unconfined compressive strength (UCS). The variations of lime and cement content used are 0%, 5%, 10%, and 15%, with lime and cement ratios of 30:70, 50:50, and 70:30. The tests conducted include physical property analysis, standard compaction, and UCS testing. The results of the study show a significant improvement in both UCS and optimal soil compaction after stabilization treatment. The optimal additive combination for improving soil quality was found at a 10% additive content with a 50:50 lime-to-cement ratio, which produced a UCS value of 14.2 kg/cm². This indicates that the use of lime and cement as stabilization materials can enhance soil strength and stability, making it suitable for use in construction in areas with poor soil conditions. This stabilization can also serve as a solution to increase soil bearing capacity, reduce potential damage, and improve soil performance in various construction applications.

Abstract

Abstract. Public buildings are buildings used by people from various walks of life, which are built or intended not for the benefit of private residences, but for the general public which are identical to community service centers (Siti Azizah, 2013). One of the public buildings is the Johar market, Semarang. An important aspect of a public building is fire safety. The purpose of this study was to determine the level of reliability of the public building security system against fire hazards in the Johar Semarang market (Johar Selatan), and the readiness of the occupants of the Johar Semarang market building in the face of fire disasters. The method used in this research is descriptive-quantitative research method which is collecting data obtained from interviews, field notes, personal documentation, researcher notes, and other supporting documents. The results of the analysis of the utility component assessment of the four variables resulted in a Building Safety System Reliability Value (NKSKB) of 86.12%, based on these results it can be concluded that the reliability value of the building is in good and safe condition. The level of readiness of residents in facing the danger of fire disasters is still in the poor category with an average level of readiness of residents of 51.12%. This shows the need for increased application of protection systems and rescue facilities, especially for several protection systems that are still damaged and not functioning as well as socialization to residents regarding the use of fire extinguishers, fire simulations, and the need to provide adequate PPE.Keywords: Public Buildings, Level of Reliability, Occupancy Readiness

Abstract

Masih adanya pemerintah daerah yang belum mensinkronkan dokumen Strategi Sanitasi Kabupaten/Kota (SSK) dengan dokumen perencanaan pembangunan daerah lainnya serta menginternalisasikan dalam proses perencanaan dan sekaligus menjadikannya sebagai mesin penggerak pembangunan sanitasi dalam mencapai target pembangunan sanitasi. Dalam rangka mewujudkan peran pemerintah daerah serta upaya menutup gap pengelolaan sanitasi pada kegiatan implementasi dokumen SSK, maka perlu ada satu metode pendampingan dalam bentuk peningkatan kapasitas aparatur pemerintah daerah. Adapun metode yang digunakan adalah metode blended learning. Metode blended learning merupakan kombinasi empat metode belajar, yaitu: pelatihan termoderasi, e-learning, buddy system dan pendampingan teknis. Tujuan pembelajaran dijabarkan secara bertahap mulai dari level pemahaman awal hingga level pemahaman yang ingin dicapai oleh peserta serta dirumuskan sesuai substansi yang akan diajarkan, terukur, singkat, dan jelas. Pembelajaran melalui webinar membantu proses diseminasi pengetahuan dalam skala besar karena adanya fitur recorded webinar, dan dapat diakses oleh audiens yang tidak mengikuti webinar. Hasil dari kegiatan bahwa sosialisasi jadwal webinar harus dilakukan secara aktif agar audiens mengetahui jadwal webinar yang akan diselenggarakan. Metode blended learning sangat efektif membantu proses transfer knowledge dan pemahaman serta dapat memotivasi peningkatan kapasitas pengelola sanitasi di daerah.

Abstract

Abstract: Layanan sanitasi adalah salah satu bentuk pelayanan dasar yang wajib didapatkan oleh masyarakat. Dalam rangka mewujudkan peran pemerintah daerah untuk mengetahui capaian layanan sanitasi dan menentukan target layanan sanitasi layak dan aman, maka diperlukan penyusunan dokumen perencanaan pembangunan sanitasi. Kegiatan penyusunan dokumen tersebut menjadi tanggung jawab pemerintah daerah dalam mewujudukan pengelolaan sanitasi yang baik. Pada realita di daerah, dikarenakan masing-masing dinas mempunyai kegiatan rutin mengakibatkan proses penyusunan dokumen perencanaan pembangunan sanitasi tidak sesuai yang diharapkan. Oleh karena itu diperlukan pendampingan dalam penyusunan dokumen perencanaan pembangunan sanitasi dengan menggunakan pendekatan pembelajaran pada pemerintah daerah. Metode pembelajaran yang digunakan pada masa pandemi covid dengan melakukan pelatihan termoderasi. Pelatihan termoderasi merupakan metode dengan melibatkan pemateri dan fasilitator kelas dalam menyampaikan materi ajar pada peserta pelatihan melalui daring/luring. Tujuan pembelajaran di mulai dari tingkat pemahaman awal sampai dengan tingkat pemahaman yang mampu dicapai oleh peserta serta disusun sesuai substansi yang diajarkan, singat, jelas dan terukur. Upaya pencapaian tujuan dari pembelajaran secara optimal, perlu direncanakan dan ditentukan peserta sebagai target pelatihan, tujuan pembelajaran, ruang lingkup materi, kanal pelatihan (daring/luring), agenda pelatihan, serta pemateri dan fasilitator. Total alokasi waktu metode belajar dengan pelatihan termoderasi menjadi hal penting yang harus diperhatikan. Pelatihan termoderasi pada masa pandemi covid dengan perpaduan daring dan luring sangatlah efektif dalam proses tukar pengetahuan, pemahaman substansi materi dan dapat memotivasi dalam meningkatkan kapasitas peserta pelatihan, serta diharapkan pasca pelatihan, peserta dapat menyusun dokumen SSK yang berkualitas dan implementatif.
