Abstract

Latex is a white, milky liquid that comes out of injured plants from the Hevea brasiliensi plant. Heveabrasiliensi latex can be processed into rubber because it has good properties which contain rubber particlesin the form of poly isopropene hydrocarbons which are the main components of rubber. In this study, latexcoagulation used an organic coagulant as a latex coagulant, namely extract from pineapple fruit and liquidsmoke from rubber wood, oil palm midrib, coconut shell. The results of coagulation were measured by thequality of dry rubber content (KKK) and PRI. Supported by secondary data, namely literature taken fromjournals and browsing on the internet. The results showed that the best coagulant material was produced bypineapple extract 80%, liquid smoke of coconut shell with a pH of 4.1, liquid smoke of palm fronds with a pHof 3.2, and liquid smoke of rubber wood with a pH of 2.6.

Abstract

Palm oil mill boiler ash is one of the substances that can be used as an adsorbent. The adsorbent can absorb certain components of a fluid phase, which before being applied needs to be activated using chemicals so that the effectiveness of the absorption is increasing. The use of adsorbents in CPO is quite effective in maintaining its quality. Several previous studies have studied the application of adsorbents in maintaining the quality of CPO. The purpose of the study was to utilize palm oil mill boiler ash as an adsorbent of several types of activators and to determine the effect of effective activator types in application to the quality of CPO oil. This study used a non-factorial completely randomized design with adsorbent activation treatment using H3PO4 and NaCl with a concentration of 10% and soaked for 24 hours. There are 3 parameters observed in the adsorbent application to CPO, namely free fatty acids, water content, and dirt content. The results showed that the adsorbent activated with H3PO4 was an effective adsorbent with a decrease in its free fatty acids up to 0.43%, water content decreased to 0.07%, but an increase in CPO impurities content of 0.24%. While the adsorbent activated using NaCl showed free fatty acids 0.22%, water content decreased by 0.03% and dirt content also increased by 0.24%. Keywords:   adsorbent activator, crude palm oil, boiler ash, H3po4, Nacl

Abstract

The burning of shells and fiber as boiler fuel in palm oil mills produces waste in the form of ash which is not utilized and managed optimally, resulting in environmental damage. Based on the chemical compounds contained in fly ash, its abundant availability, its cheap price and easy-to-obtain, fly ash can be used as a cheap raw material in claybaths as a substitute for clay and calcium carbonate. This study aims to determine the effective weight of boiler ash in reducing kernel and shell production losses at the kernel processing station. This study used variations in the weight of boiler fly ash, namely 3000 g, 3500 g, 4000 g, 4500 g, and 5000 g which were tested first in the laboratory. The application of boiler ash variations that were close to the norm was tested directly in the claybath. The best weight parameter for using fly ash is found in the weight variation of B5 (5000 g) with a loss of production in the sample of 3.98% or 0.159% of the oil palm fresh fruit bunches. At the time of application, boiler fly ash should be mixed with water at a ratio of 1:2 (fly ash to water) to result the best effect. Key words : Boilers, Clay bath, Fly Ash, Kernel, Shell

Abstract

Efisiensi turbin merupakan sebuah parameter dari derajat keberhasilan system turbin untuk mendekati proses ideal dengan satuan persen (%). Efisiensi turbin diketahui dengan membandingkan kerja ideal turbin dengan kerja aktual turbin. Laju massa uap adalah jumlah uap yang mengalir ke turbin uap dalam satuan waktu. Penelitian ini bertujuan untuk mengetahui pengaruh laju massa uap terhadap  nilai efisiensi turbin uap. Penelitian dilaksanakan pada 3 oktober-16 oktober 2023 di pabrik kelapa sawit kapasitas 50 ton/jam. Adapun metode yang digunakan dalam penelitian ini yaitu menggunakan metode Deskriptif Kuantitatif berdasarkan data primer pada turbin uap. Rata-rata laju massa uap yang terjadi pada 3 oktober-16 oktober 2023 yaitu 6,70 kg/s atau 24,12 ton/jam. Sedangkan rata-rata efisiensi kerja turbin uap pada periode yang sama 32,69 %. Nilai efisiensi kerja turbin uap tertinggi yang tercapai pada 3 oktober-16 oktober 2023 di pabrik kelapa sawit Kapasitas 50 Ton/Jam yaitu 37,365% dengan laju massa uap 6,38 kg/s. Dari penelitian ini dapat diketahui bahwasanya laju massa uap berpengaruh signifikan terhadap efisiensi kerja turbin uap, dapat dilihat dari koefisien persamaan regresi yang negatif, yang berarti semakin besar laju massa uap, nilai efisiensi turbin uap juga akan menurun, begitu pula sebaliknya.

Abstract

Palm oil empty fruit bunches (EFB) and fronds are solid waste originating from palm oil processing which can be used as the main raw material for making briquettes. This is supported by its contents, namely lignin, hemicellulose and cellulose. The smaller the particle size, the greater the compressive strength of the briquette, but the burning rate will be slower because the cavity/pores of the briquette are smaller. This research aims to determine the effect of particle (mesh) size on the characteristics of briquettes which include water content, ash content, density, compressive strength and burning rate as well as to determine the best composition of a mixture of empty oil palm fruit bunches and fronds. The results of this research show that the best particle size is 70 mesh briquettes with a raw material composition of 46% EFB and 46% fronds (1:1) with 8% tapioca flour adhesive. Biobriquettes with small particle sizes have lower calorific value. The results of this research indicate that the manufacture of briquettes is in accordance with the Standard Characteristics of SNI No. 1/6235/2000.

Abstract

One of the environmental problems in Indonesia is plastic waste which is made from synthetic materials. This synthetic plastic waste is very difficult to decompose in the soil and takes 300-500 years to completely decompose. Therefore, bioplastic is an alternative to this problem. The purpose of this journal review is to calculate the cellulose potential of empty bunches (EFB) and oil palm midribs (PKS) through several processes, namely the delignification process and the bleaching process. ) 31.7%. So it can be said that empty fruit bunch cellulose (TKKS) and palm fronds (PKS) have enormous potential to meet the needs of bioplastic raw materials.
