Abstract

Utilizing dead rock as a cement additive in the manufacture of paving blocks, and the rock contains CaCO3 which includes limestone as in the content of cement which has lime content (CaO), the aim is to determine the effect of rock on the compressive strength value of paving blocks. Utilization of stone in the manufacture of paving blocks using a mixture of design 0%, 5%, 10%, and 15% of the weight of cement to be used. Manufacture of paving blocks using a ratio of 1: 3 sand cement, cement water factor 0.4 with molds 20 x 10 x 6 cm, compaction weight of 1 paving 3.52 kg and testing compressive strength at 7, 14 and 28 days, using the method (SNI 03- 0691-1996) paving block. From the analysis of compressive strength testing, it was found that the compressive strength of paving blocks increased towards normal paving blocks to produce the highest compressive strength with added rock in the 15% variation at the age of 28 days, which amounted to 45.1 MPa and included the quality of class A paving blocks with SNI 03-0691 (1996) standards. The compressive strength of the 5% variation at 28 days of age is 38.7 MPa and the compressive strength of the 10% variation at 28 days of age is 43.5 MPa. It can be seen that coral stone as a cement additive is able to improve the quality of compressive strength of paving blocks.

Abstract

The number of two-, four- or four-wheeled motorized vehicles is increasing in Jepara Regency. With the increasing number of vehicles, it is estimated that roads will experience damage in a relatively short time. The aim of this research is to determine the effect of vehicle traffic on the level of road damage and the relationship between vehicle traffic and the level of road asphalt damage. The method used to determine the value of road damage is the PCI method and the level of road damage uses the non-linear multiple regression method. This research was carried out on two roads, namely Jalan Keongsari – Blebak and Jalan Karanggondang – Mpurancak. It is known that the average damage that occurs on the Keongsari - Blebak road section is 39.29 (BAD) including the Overlay maintenance type, while the Karanggondang - Mpurancak road section has an average damage value of 67.14 (GOOD) if routine maintenance is carried out. pen type. The results of measuring the thickness of the additional layer (overlay) using the road composition analysis method on the Keongsari – Blebak road section obtained an additional layer thickness of 5 cm using LAPEN material. Meanwhile, the results of the relationship between vehicle traffic and road damage show that traffic (pcu/hour) and time (hours) have a large influence on road damage. This is shown by the results of determining the R2 coefficient of 86%. Keyword: Damage, Road, Flexure, Overlay, Highway.

Abstract

Jepara yang banyak bergerak di industri furniture yang mencakup pengelolaan kayu dan yang lain di jepara juga terdapat pltu tanjung b jepara yang mana hasil dari pembakaran batu bara menghasilkan limbah yang berupa fly ash, banyak nya limbah yang berupa fly ash dan serbuk gergaji kayu dalam upaya mengurangi limbah tersebut dimanfaatkan sebagai bahan tambah pada semen dalam proses pembuatan paving block, penelitian ini dilaksanakan dengan tujuan untuk mengukur tingkat kekuatan tekan dan tingkat penyerapan air dari paving block yang dihasilkan. Pada penelitian yang telah di lakukan dengan variasi campuran 0%, 2,5%, 5%, 7,5%, 10% mengalami kenaikan dari umur 7 hari kuat tekan tertinggi nya di variasi 10% dengan nilai 31,8 MPa, di umur 14 hari kuat tekan tertinggi nya di variasi 10% dengan nilai 37,1 MPa, umur 28 hari kuat tekan tertinggi nya di variasi 10% dengan nilai 39,1 MPa, dikategorikan menurut SNI 03-0691-1996 masuk kedalam mutu B. Untuk penyerapan air nya mengalami pemadatan jadi penyerapan air nya menurun dari 0% ke 10% dengan nilai 3,393 – 3,192 dikategorikan menurut SNI 03-0691-1996 masuk kedalam mutu B karena nilai nya lebih dari 3%.

Abstract

This community service activity was carried out to improve the management of the Waste Bank in Krapyak Bersinar through training and mentoring in the use of a web-based information system. The main problem faced by the Waste Bank is manual transaction recording, which often results in errors, data loss, and a lack of transparency. Furthermore, managers also have a limited understanding of accounting and financial management in accordance with standards. Therefore, the objective of this activity was to provide training to Waste Bank managers on the use of an information system application that can simplify transaction recording and financial reporting. The methods used in this activity included problem identification through interviews and observations, socialization regarding the importance of technology in Waste Bank management, training in the use of the web-based application, and mentoring in implementing the application. The results of the activity showed that with the web-based application, Waste Bank managers can record transactions more accurately and efficiently. In addition, the resulting financial reports are more transparent and accountable. The evaluation showed that 90% of managers found it easier to record transactions and manage customer data, and 85% reported a reduction in recording errors. In conclusion, this training and mentoring successfully improved the operational efficiency of the Waste Bank in Krapyak Bersinar, as well as increasing managers' understanding of the use of information technology for better financial management.
