Eco-paving block is a product used for construction consisting of sand and plastic mixes. In order to produce eco-paving blocks, the mixture of sand and concrete was substituted in part with sand and plastics. In order to properly mix plastics to create eco-paving blocks, a plastic smelter was used to generate heat and melt the plastic materials. The plastic material types used in this case was PETE or PETE, which has the characteristics of being flexible and high adhesive properties; along with ABS which can stand pressures. Based on the tests conducted with the plastic smelter using PET, ABS, and the combination of PET and ABS, the most promising result was shown with the combination of PET and ABS. This combination required 8 minutes 21 seconds for the plastics to become fully melted, and a temperature of 278oC. The combination of PET and ABS resulted in a mixture of plastics with strong adhesive properties and durability. This product could potentially be developed into eco-paving blocks. Additional studies regarding the optimum dosage combinations of PET and ABS plastics in eco-paving blocks can potentially be established in order to further optimize the usage of these plastics in eco-paving blocks.

Petroleum fuels are increasingly limited in resources making the theme of sustainable energy one of the top issues in the world. Supported by increasing awareness of clean and sustainable environments. Biofuel derived from vegetable oil is a renewable energy that has the potential to be developed in Indonesia, given that Indonesia is rich in biodiversity. Used cooking oil is used cooking oil produced from vegetable oil which has the potential to produce biofuels. Used cooking oil is non-edible and can even be said to be waste, so its use as a fuel does not compete with food oil and has a calorific value that is almost the same as conventional fuel. The process of catalytic cracking of used cooking oil has been carried out in this research. The cracking process is carried out using a Zeolite catalyst that has been impregnated with Fe. Catalytic Cracking is carried out on a distillation flask with catalyst variations, catalyst size and temperature as independent variables. Fe / Zeolite catalyst variations are 1%, 3%, 5%, and 7%, with sizes 60, 80 and 100 mesh, while the temperature variations are 250oC and 350oC. Whereas the dependent variable is time, which is 2 hours. The optimum results obtained with the greatest yield on the use of catalysts with a catalyst concentration of 3%, catalyst size of 60 mesh and a temperature of 350oC. The physical test carried out was a specific gravity test that was equal to 0.8241 at the optimum yield with a catalyst concentration of 3%, and 1.0392 on the use of a catalyst with a concentration of 5%. From the results of the GCMS test shows that the component that dominates the biofuel produced is gasoline seen from the C6 compound content of 17.2% and C8 of 13.7%. It can be said that the largest amount is biogasoline shown by the presence of C5-C11 compounds of 72.4% than biodiesel indicated by the percentage of C12-C15 of 24.1%

Pengelolaan sampah suatu kota bertujuan untuk melayani sampah yang dihasilkan penduduknya, secara tidak langsung turut memelihara kesehatan masyarakat serta menciptakan suatu lingkungan yang bersih, baik dan sehat. Saat ini pengelolaan persampahan menghadapi banyak tekanan terutama akibat semakin besarnya timbulan sampah yang dihasilkan masyarakat baik produsen maupun konsumen. Semua sampah dari sumber masing-masing akan bermuara ke tempat pemrosesan akhir sampah (TPA) Sumur Batu. Kecamatan Bantar Gebang merupakan daerah yang masuk wilayah Kota Bekasi dan memiliki dua lokasi TPA, yaitu milik Pemerintah Kota Bekasi di Sumur Batu dan yang satu milik DKI Jakarta di Bantar Gebang. Berdasarkan hal tersebut penulis memilih untuk melakukan penelitian terkait implementasi kebijakan dan strategi pengurangan sampah dari sumbernya. Dalam hal ini yang menjadi sumber penghasil sampah adalah kegiatan di Universitas Bhayangkara Jakarta Raya (UBJ) yang diperkirakan menghasilkan jenis sampah tertentu/khusus. Metodologi penelitian yang dilakukan adalah pengukuran langsung di lapangan dengan mengacu pada SNI 19-3964-1994 tentang metode pengambilan dan pengukuran contoh timbulan dan komposisi sampah. Hasil sampling diperoleh bahwa volume sumber sampah rerata 1,68 m3/hari (123,43 kg/hari). Secara umum komposisi persampahan UBJ yaitu 58,53% organik dan 41,47% an organik. Untuk sampah an organik, komposisi sampah yang dianggap berpotensi secara ekonomis terdiri dari 3 (tiga) jenis sampah dengan prosentase > 10% untuk bisa dimanfaatkan menjadi bahan bakar sintetis dan bahan kertas daur ulang. Bahan tersebut adalah Botol plastik 14,33%, Kertas 15,00% dan plastik lembaran 13,37% (jumlah sampah yang bisa dimanfaatkan 42,7%). Usulan tata kelola adalah dengan pemberdayaan unit kegiatan mahasiswa dalam pemilahan sampah yang bernilai ekonomis. Sedangkan untuk usulan teknis diharapkan bisa menampah space untuk area penerimaan, timbunan dan area pemilahan seluas ± 55 meter persegi.

The phenomenon of rampant acts of child prostitution causes children to lose their rights in relation to their protection, prostitution that makes children as victims is certainly an act that violates the law and decency, when children have to get education and study but instead get bad treatment and consequently hindered to live his life. In its development, prostitution which was originally a conventional crime became an unconventional crime where children can be victims or traded online through Facebook and Instagram in carrying out transactions or agreements through pimps or brokers. The impact of prostitution on children is that the child will be depressed, depressed and have a lot of daydreaming and not concentrating on learning while related to health can damage the reproduction of girls and cause infectious diseases such as AIDS/HIV. In addition, the factor of the occurrence of prostitution is due to economic factors where it is difficult to meet the necessities of life so that it justifies all means, and prevention can be done by increasing the family's understanding of the importance of child protection through an understanding of human rights, developing knowledge about the impact of prostitution on children and being consistent. to protect and supervise and guide children so as not to fall into the trap and also the need for the role and concern of the community to actively participate and be consistent and care about the government's efforts to provide guidance and supervision so that the practice of prostitution by minors does not occur again

The extraction process is a process of separating a substance based on its dissolution difference against two different dissolved liquids, usually water and the other an organic solvent. Vegetable oil is an oil that can be extracted from various parts of the plant that is processing the stems, leaves, seeds, flowers and fruit peel. Seed is one of the main ways plants to regenerate. Seeds contain large and distinct quantities of macromolecule reserves, which are stored as a source of spare food to support early germination. As an alternative to the healthful drugs of the body from various diseases that will attack the human body and have other important benefits. In this study used an extraction research method that produced vegetable oils in using 30 grams of mango seeds each on a 6-time process with ethanol and hexane solvents which used 500 ml each at a given time. From a good yield yield obtained at 3 hours of extraction process with ethanol solvent having a yield of 50%, then having a good quality is obtained by the yield of vegetable oil by using ethanol solvent. Thus the vegetable oils of the extraction process have a good oil content in the ethanol solvent versus hexane.

PT.XYZ So research was carried out so that we could find the critical path for a house construction project using the CPM method, the duration of the critical path for building a house, and how much budget was spent on building a house using the CPM method. CPM is a project management concept which is interpreted in a network image that marks project activities from start to finish with the aim of determining the critical path and PERT is a network model that is able to determine the completion time of activities. The aim is to assess and review development projects and requires three calculations. optimistic, pessimistic and realistic. The results of this research show that house construction project work using the CPM method has a work duration of 182 days, a decrease of 118 days from the actual duration and the costs incurred in this work are IDR 1,956,043,000. can reduce the budget by IDR 771,914,000/35% of the actual budget. The house construction project produces a Te value of 182.48 and a standard deviation value of 8.09 and has a probability of 53.59% if the project is completed within 182 days. However, if you use the assumption that the project can be completed within 190 days, the probability is 83.89%.
