Liquid wax (wet wax) is a source of heat energy and lighting produced from palm oil to provide illumination where needed. The need for candles is used for lighting the environment, the place, and the heating of the objects for need. The manufacture of liquid candles is to provide the base oil of crude palm oil mixed evenly in the melting point of solid paraffin. Paraffin and CPO are melted together and placed, then cooled. The wax ignition process produces heat and light. Results that can be shown with a comparison between palm oil and solid paraffin will produce hardness, texture, and flame ignition. With 50 grams of paraffin, 50 gr CPO and 1 kg of oxygen (1: 5) of the fuel of 250 gr O2, will produce 1300 gr CO2, 1175gr H2O, -1487,5 gr O2 and 940 gr N2. Different paraffin granules, will produce the same product in energy balance, while the value of N2 remains. Experimental value from mixing CPO and paraffin by 50 gr: 50 gr yielding entropy generation (S gen) and CPO wax exudo of 257.16 kJ / kmol.K and 77,918.67 kJ/kmol and its value decreases based on paraffin administration

Palm oil fibers are waste products from Palm Oil Mill which is in the form of debris, solid, length of 3-4 cm, contained in coconut fruit (mesocarp) meat. Fiber roof building is the result of utilization of palm fiber waste as a roof of a building that is used to reduce heat from sunlight or from heat sources, so it is not directly exposed to humans and the surrounding environment. Fiber roof building is made by arranging the fiber in the mold and arranged in accordance with the dimensions to be made. To bind between fibers, used resin that has been mixed with the catalyst material, so easy to dry quickly. The ratio between resin and fiber is 1: ¼. The result of conduction heat conduction test that has been done on the fiber test object can reduce the highest heat of 125 °C and the lowest is 109 °C from the given heat source of 200 °C. This shows that palm fiber can be used as a heat reducer for buildings.

Indonesia is one of the developing countries and is actively pioneering development, especially development in the industrial sector. The industry that is quite developed at this time is the manufacturing industry which produces a finished product that can be directly used by consumers. These products are expected to have a high enough quality level so that they can compete in the market. To support this quality, one of the factors is to pay attention to the level of precision of the workpiece in this case is the level of surface roughness of the object or product produced. The surface roughness value is obtained from the tests carried out on the product which has an average surface value (Ra) and a maximum roughness value (Ry). To achieve the desired roughness value, it is necessary to make improvements in metal forming work. In the variable cutting with variations in cutting speed, it is said that the cutting speed on work with smaller diameter objects should use a high cutting speed. Feeding thickness that is too large can cause high surface roughness values and high rotation at low cutting speeds to produce a smooth surface but takes a long time. With the selection of the speed of ingestion that varies for the price of the ingestion speed of 43.52 m/minute, the surface roughness value is 6.78 m, the speed is 48.32 m/minute, the surface roughness value is 3.64 m and the ingestion speed is 59.25 m. /min the surface roughness value is 6.14 m. Meanwhile, for the infeed thickness which varies for a feed thickness of 1.2 mm, the surface roughness value is 4.06 m; a feed thickness of 2.4 mm obtained a surface roughness value of 27.82 um and a feed thickness of 3.2 mm obtained a surface roughness value of 7.02 m.

Throughput is the ability of a company's production unit to process raw materials into final products that have value, in accordance with established standards. Palm Oil Mill (PKS) is a processing company for raw materials in the harvest of palm oil in the form of Fresh Fruit Bunches processed into Crude Palm Oil (CPO) and Palm Kernel Oil (PKO) products and their by-products in the form of solid waste (empty bunches, fiber, shells) and liquid. PKS production can be achieved throughput produced by looking at the production process that occurs in each work unit, namely: the value of the capacity of the stew is done, sequencing time, steam boiler requirements, Material Balance. The capacity owned by PKS XYZ is 60 tons/hour, does not meet the targeted throughput, where the sterilizer capacity is only able to reach 45 tons/hour, sequencing time is 45 minutes, the steam boiler produced is not sufficient to produce 60 tons of PKS/hour, and the existing Material Balance is not met, which are 38 tons/hour.

This plan aims to minimize wasted energy in the air freshener system and utilize the wasted energy to heat water. Here using a split type air conditioner system which is commonly used. The author slightly modified the air conditioning system which previously used an air conditioning condenser, here the author added a condenser with a water cooler that functions as a condenser and at the same time as a water heater. The energy used to heat the water is obtained from the heat released by the refrigerant so as to minimize the energy wasted when only using an air conditioning condenser. But the air conditioning condenser is still used in this system, because when hot water is not needed, the water in the heater does not flow and of course cannot take heat from the refrigerant. In this condition the air conditioning condenser can work to help the process of releasing heat from the refrigerant. This tool can heat water up to 43oC with a flow rate of 1 liter per 9 seconds which can be used at home, SOHO, office for bathing, washing face, washing hands, etc.

“UMKM telah menjadi backbone dan buffer zone yang menyelamatkan negara dari keterpurukan ekonomi”, kalimat ini senantiasa didengung-dengungkan dalam setiap pertemuan para birokrat dan pakar serta pengamat ekonomi. UMKM pun menjadi sorotan dan senantiasa diteropong dalam berbagai masalah nasional berkenaan dengan, penanggulangan kemiskinan, pengangguran dan kenaikan nilai PDB (Product Domestik Bruto) negara. UMKM diyakini berpotensi memberi sumbangan bagi pertumbuhan ekonomi nasional. Secara historis UMKM dalam kegiatan ekonominya lebih menonjol pada moral (agama) dan budaya daripada terstruktur dalam teori-teori profit, maksimalisasi dan free kompetitif. Dalam teori Antropologi Ekonomi kerap dideskripsikan bahwa, proses ekonomi dalam masyarakat UMKM menggambarkan bentuk perilaku yang ber tipe kekerabatan, terikat pada ritual keagamaan, berbagi rezeki dan juga resiko serta menuntut “kepercayaan” dalam transaksi di antara mereka. Fenomena inilah sesungguhnya yang memungkinkan pengusaha UMKM lebih tahan dalam menghadapi krisis, refleksi penelitian penulis terhadap ekonomi usaha kecil di kota Jakarta. Penggambaran bentuk kegiatan ekonomi ini menjadi dasar pemikiran penulis ketika para ahli tengah mencari bentuk sistem ekonomi nasional yang berbasis ekonomi rakyat dan ketika para pelaku UMKM cenderung dijadikan sandaran untuk menyelesaikan permasalahan ekonomi nasional.

Mesin Air Blast Freezer (ABF) adalah salah satu alat pembeku makanan dalam dunia refrigerasi. Dalam perancangan Air Blast Freezer ini, tahapan yang paling menentukan adalah saat perhitungan beban kalor yang akan menjadi acuan bagi perancang dalam pemilihan kompresor. PT. XYZ dalam hal ini untuk memenuhi permintaan pelanggan untuk 2 unit ruangan ABF dengan kebutuhan membekukan adonan roti berkapasitas 250 kg/jam di tiap ruangan melakukan perhitungan beban kalor ABF dengan asumsi total beban kalor sebesar 41,5 kW dan menggunakan kompresor 62WBHE 900rpm sebagai penopangnya. Sehingga saat ini terdapat 2 kompresor tipe 62WBHE 900rpm yang berjalan, dan 2 unit kompresor yang sama direncanakan untuk projek 2 ABF selanjutnya. Kondisi aktual yang didapatkan dengan cara observasi dan analisa perhitungan serta pemilihan kompresor, beban kalor ternyata hanya 37,81 kW, dan cukup apabila hanya menggunakan kompresor 42WBHE 900rpm yang ukurannya lebih kecil dan kebutuhan dayanya juga lebih kecil.
