One non-organic waste that is used extensively in daily life is plastic, particularly for food packaging vendors and as a raw material for toy manufacturers. Waste will result from the vast amount of plastic that residents of Medan Krio use and discard after consumption. The goal of the research program's implementation is to enable locals to recycle waste materials to create valuable products. The village of Medan Krio Village has a high population density, which has led to the development of waste management issues. The village has traditionally disposed of waste by burning it and throwing it beside the street, which is why there is a garbage stench. which has a strong odor as a result of careless trash dumping. In light of this issue, Ecobricks may offer a way to lessen plastic waste and turn it into products with a positive economic impact. Method: PAR (Participatory Action Research), which is study that identifies issues and then offers potential solutions. Findings: The Ecobrick technique is being used in Medan Krio Village to make use of plastic waste.

Porous concrete is commonly used in road linings with minimal traffic, parking areas, pedestrian paths, and parks. The strength of porous concrete depends on the size of the aggregate and the correct composition of water and cement. The objective of the study was to analyse the effect of cement water factor in uniformly graded porous concrete on compressive strength and permeability in uniformly graded porous concrete on permeability values. The relationship between the compressive strength of concrete tends to decrease as the value of cement water factor increases. The water-cement factor strongly influences the permeability value. The greater the value of cement water factor, the smaller the permeability of uniformly graded porous concrete, this is due to the deposition of cement water at the base of the slab. The use of super plasticizer (SP) in porous concrete accelerates the pavement process, but does not improve permeability. cement water factor 0.35 with a 28-day treatment period obtained a Slump test value of 178 mm, cement water factor 0.5 of 192 mm, cement water factor 0.6 with a 28-day treatment period obtained a Slump test value of 196 mm. while porous concrete with a cement water factor of 0.35 has an average compressive strength of 6.13 Mpa, while a cement water factor of 0.50 has an average compressive strength of 5.47 Mpa, and a cement water factor of 0.60 has an average compressive strength of 5.00 Mpa.

Management Of External Radiotherapy Irradiation In Vaginal Cancer Using Intensity Modulated Radiation Therapy (IMRT) Technique At The Cancer Center Radiotherapy Santosa Hospital Bandung Kopo. Vaginal carcinoma constitutes approximately 2% of all malignant neoplasms that occur in the female genital tract. Vaginal carcinoma can arise from various types of cells within the vaginal wall and is often associated with risk factors such as exposure to certain carcinogens (8). Cancer is one of the main causes of death throughout the world. Based on GLOBOCAN data, the International Agency for Research on Cancer (IARC) in 2018, deaths caused by cancer reached around 9.5 million people, with 60% of cancer deaths in Asia. (7) Radiotherapy is a cancer treatment approach that uses light. ionizer to damage tumor cells while maintaining the integrity of surrounding healthy tissue. The main focus is to eliminate as many cancer cells as possible while reducing the negative impact on normal tissue around the tumor area. (20) There are several treatments for patients suffering from vaginal cancer, namely surgery, radiation, brachytherapy, and  external radiation based on the size and stage of the tumor suffered by the patient. (3) Based on the book "Target Volume Dileniation And Filed Setup" (a practical guide for conformal and Intensity-Modulated Radioation Therapy), Arno.J, (2013: 201), all vaginal cancer patients who undergo radiation using the IMRT technique must simulated in a supine position and the patient's legs straight with a thermoplastic immobilization mask and adjusted immobilization of the upper and lower body (16).

The Effect Of Use Of Lung Mask Fixation On The Accuracy Of Targeted Irradiation In Lung Cancer Intensity Modulated Radiation Therapy (Imrt) Technique In The Department Of Radiation Oncology, Jakarta General Hospital. Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. While normal cells in the lungs usually develop and reproduce to form healthy lung tissue, these abnormal cells actually reproduce more quickly and are never able to become normal lung tissue. As a result, lumps of cancer cells are formed, which are often referred to as tumors. (4) Radiotherapy is a form of therapy that has been proven to be useful in treating cancer. The aim of radiotherapy is to provide safe, accurate and efficient radiation doses to treat various types of cancer and also non-malignant disorders (7). Carrying out radiotherapy for lung cancer involves the use of immobilization devices, one of which is a thermoplastic mask. This mask functions to reduce the patient's body movements, including movements caused by breathing (9). Verification is a critical stage in the radiotherapy process. The purpose of this verification is to ensure that there are no significant differences in the exposure carried out (14). Giving the right dose of radiotherapy radiation is very necessary to achieve successful therapeutic treatment. The accuracy of dosing and the accuracy of the patient's position influence the dose distribution that will be received by the patient. This verification is based on the International Atomic Energy Agency (IAEA) Human Health Series No. 31 of 2016 with a displacement value of 0.3cm (15). EPID (Electronic Portal Imaging Device) is an additional device connected to the LINAC (Linear Accelerator) radiotherapy device. EPID functions as a verification tool for radiation dose and geometry which is very important in the radiotherapy process (16). The accuracy of the patient's position during radiation treatment greatly influences the accuracy of the IMRT technique. Before irradiation, verification is carried out using an EPID (Electronic Portal Imaging Device) to ensure the correct target position on the tumor. This helps measure the x, y, and z axis coordinates along the radiation area before the radiation procedure begins.

The problem that must be overcome by all parties is garbage. Society must take an active role to solve this problem. In an effort to safeguard the environment, the Maju Jaya Waste Bank has a role in sorting and processing waste. Organic waste will become fertilizer. Plastic or non-organic waste will be the raw material for the Paving Blok Prima Lestari Bumi Group. Paving Block Prima Lestari Bumi Group will process plastic waste into paving blocks. However, there are several problems faced. The problem faced by Prima Lestari partner Bumi Paving Blok, such as the lack of supply of raw materials for plastic waste, lack of operational equipment, which causes the production of paving blocks cannot maximize. The level of sales still cannot meet the target per month. Current marketing aspects are carried out by word of mouth and take part in exhibitions carried out by the local government or using social media. For Maju Jaya Garbage Bank, the problem is a large amount of operational costs to sort waste based on the type of waste. This is inversely proportional to income from processed products that are less than optimal. Some of the solutions offered to partners are several parts of training for the sale of goods, procurement of operational goods such as production machinery for paving blocks and machines that can sort waste by type to reduce operating costs.

Latar Belakang: Lymph node cancer in the case of Hodkin's Lymphoma is a type of cancer. Lymphoma is a solid tumor of the immune system. Hodgkin lymphoma (HL) accounts for about 10% of all lymphomas. The Intensity Modulated Radiation Therapy (IMRT) technique is one of the cancer treatment techniques in Hodgkin's Lymphoma cases. The aim of this research is to determine the procedure and reasons for using the IMRT technique in lymph node cancer in Hodkin's Lymphoma cases.Metode: This research is qualitative research with a case study approach using retrospective data. The research time is from 24 to 30 May 2023 and the research location is in the Department of Radiation Oncology, RSUP Dr. Hasan Sadikin Bandung. The research subjects consisted of Radiation Oncologists, Medical Physics, Radiotherapists. Researchers collected data from patient medical records, made interview transcripts and carried out data reduction and processed it using open coding, and provided it in the form of quotations and then drew conclusions.Hasil: The procedure for irradiating Hodgkin's Lymphoma using the IMRT technique at the RSHS Department of Radiation Oncology begins with positioning the patient on the examination table with a fixation device and arranging the patient according to the reference point of the CT Simulator and making a thermoplastic mask then carrying out verification and irradiation. The IMRT technique has the advantage of using MLC so that the radiation is modulated according to the contour of the target and the disadvantage of precise dose distribution in limiting the radiation dose to organs at risk.Kesimpulan: In the case of the Department of Radiation Oncology, Dr. Hasan Sadikin Hospital, Bandung, the IMRT technique was used with consideration, namely that the IMRT technique already uses MLC which creates individual blocks automatically according to the projections depicted on the TPS.
