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

Acceleration of processing for fresh fruit bunches (FFB) is crucial to increase profitability and business opportunities for oil palm farmers. This research aims to evaluate the effect of using gamal (Gliricidia sepium) leaves and the duration of ripening on the percentage of FFB processing as well as the quality of crude palm oil. This study employed a factorial completely randomized design (CRD). The data were analyzed using ANOVA with Duncan’s Multiple Range Test at a significance level of 5%. The results of the analysis showed that the best treatment was S3T2 (40% gamal leaves, 20 h of ripening) with a natural processing percentage of 45.87% of the FFB weight and 60.34% of the total bunch weight. The use of gamal leaves and the duration of ripening significantly affected the quality parameters of the oil, especially the free fatty acid content. Treatment S1T1 (20% gamal leaves, 10 h of ripening) showed the best results with a free fatty acid value of 1.30%, meeting the quality standard (<5%). However, the moisture content still exceeded the quality standard (<0.5%), although treatment S3T2 yielded the best result at 0.63%. While, the impurity content quality met the quality standard (<0.5%), with the best value achieved by treatment S1T1 at 0.15%. Keywords: Bunch detachment, CPO quality, Ethylene, Gliricidia sepium, Ripening.

Abstract

Coagulants are commonly used in rubber plantations to coagulate latex. This study aims to determine the effect of incubation time and dose of starfruit extract on coagulation speed, total solid content (TSC), and weight loss of the resulting coagulum. The study was carried out at the Sungei Putih Research Unit, Indonesian Rubber Research Institute in September – October 2023. A Completely Randomized Design (CRD) was applied with two treatments, namely, the incubation period for the extract (A) which consisted of three levels (0 days (A1), 2 days (A2), and 4 days (A3)) and the extract dose (B) consisting of three levels (3 ml (B1), 6 ml (B2), and 9 ml per 20 ml latex (B3)). Each treatment combination was repeated three times. The results indicated that the degree of acidity (pH) of starfruit extract without incubation was around 2.8. After incubation for 2 days, the pH decreased to 2.7, and after 4 days to pH 2.5. The fastest coagulation was obtained in treatment A3B3 for 2.03 minutes after mixing, while the longest was in treatment A1B1 for 7.07 minutes. The highest coagulum TSC was obtained in the A3B1 treatment at 50.30%, while the lowest was in the A2B3 treatment at 27.47%. The highest level of weight loss was found in the A2B2 treatment at 36.80%, while the lowest was in the A3B3 treatment at 23.01%. The use of high doses of starfruit extract can coagulate latex in a short time with low weight loss; thus, it can be used as an organic coagulant.

Abstract

Hadirnya perguruan tinggi baik swasta dan negeri memberikan sumbangan tenaga ahli lulusan mahasiswa di setiap tahunnya, akan tetapi dengan predikat sarjana hal tersebut belum tentu menjanjikan untuk mendapat pekerjaan yang sesuai, terkadang dari banyaknya lulusan tak semua terserap di lapagan pekerjaan yang menyebabkan pengangguran. Pemberdayaan mahasiswa dan lulusan melalui kewirausahaan dianggap sebagai salah satu solusi untuk mengurangi pengangguran. Kegiatan pengabdian ini dilakukan bertujuan untuk memberikan ilmu pengetahuan, informasi tentang wirausaha, minat untuk berwirausaha, menyampaikan secara nyata manfaatnya dalam mencegah pengangguran di kalangan mahasiswa/lulusan. Kegiatan pengabdian ini dilaksanakan dengan beberapa tahapan yaitu, pembekalan dari mata kuliah Technopreneur dan Pemasaran Produk Perkebunan yang berisi mulai dari dasar-dasar entrepreneurship, perencanaan bisnis, manajemen keuangan, pemasaran, inovasi, keterampilan komunikasi, hingga membuat satu proposal bisnis yang produknya dijual pada kegiatan bazar di kampus pada bulan Juli 2023 yang dibagi ke dalam 8 kelompok. Dari kegiatan pengabdian ini diketahui bahwa mahasiswa ITSI memberikan tanggapan yang positif dan memiliki keinginan untuk berwirausaha sebagai alternatif setelah lulus selain mencari pekerjaan sebagai pegawai di perusahaan. Terdapat 90% menyatakan setuju bahwa mereka ingin membangun usaha sendiri dengan harapan dukungan dari lingkungan keluarga dan modal yang cukup sehingga mereka bisa menciptakan lapangan kerja bagi diri sendiri maupun masyarakat.
