Abstract

Crude Palm Oil is one type of vegetable oil that is extensively utilized in many different industries around the world, one of which is as a basic ingredient for cooking oil products. In Indonesia, Palm oil is among the abundant agricultural commodities. Therefore, palm oil is the right decision to address community needs across a range of domains. Crude palm oil has a high beta-carotene content, an initial compound of vitamin A, which gives the oil a reddish color. The dominant color of red or orange fruits or vegetables is a characteristic of crude palm oil from other types of vegetable oils. This investigation was carried out to examine the impact of adding aromatic medicinal plant extracts on the aroma and taste characteristics of palm oil when high water content increases free fatty acid levels that can cause CPO rancidity. Various experimental methods were used with data obtained from a careful literature review. The final results showed that variations in the addition of these ingredients significantly affected the aroma and taste of palm oil, highlighting the potential for innovation in product development and the food industry with repeated frying processes.

Abstract

Penelitian ini bertujuan dapat berguna bagi dunia Perkebunan termasuk Pabrik Kelapa Sawit dalam melakukan perawatan pada mesin untuk memaksimalkan kinerja mesin dalam melakukan pengolahan sawit menjadi Crude Palm Oil. Metode Penelitian yang digunakan adalah menggunakan metode studi kasus dengan mengamati, merangkum dan mencatat data sekunder maintenance dari jurnal harian mandor berupa waktu operasi, Frekuensi Breakdown, Failure and Repair dan Set and adjusment selama 6 bulan mulai dari proses pengolahan pabrik sampai akhir. Penelitian ini dilakukan untuk mencari kehandalan pada mesin Induce Draft Fan dan menghitung ketersediaan mesin dalam waktu 1 bulan, kemudian memeriksa komponen-komponen yang ada pada pabrik kelapa sawit. Ada beberapa komponen yang masih dapat dihandalkan atau masih layak digunakan dan ada komponen yang rusak total. Dari data hasil penelitian kondisi yang memiliki ketersediaan yang tinggi adalah bulan juni sebesar 71,3% sedangkan kondisi ketersediaan yang rendah adalah bulan November sebesar 6,36% yang artinya kondisi pada bulan November mengalami kerusakan yang sangat parah. Kerusakan yang terjadi pada bulan juni sebesar 28,7% sedangkan kerusakan pada bulan November sebesar 93,64%, Kemudian untuk bulan juli dan oktober tidak dilakukan penghitungan reliability dan availability karena kondisi tersebut tidak menyebabkan breakdown total.

Abstract

This study aims to determine soil pH values using various dilution levels with water (H₂O) and 1 N KCl solution, and to analyze their effects on soil acidity and its implications for soil fertility. Soil pH is an important indicator that influences nutrient availability and plant growth, particularly in oil palm cultivation. The research was conducted in an ITSI Soil Laboratory by mixing air-dried soil with H₂O and KCl in ratios of 1:1 and 1:2.5. The results showed that soil pH mixed with water ranged from 5.3 to 5.8 (slightly acidic), while soil mixed with 1 N KCl had lower pH values, ranging from 4.2 to 4.4 (strongly acidic). The decrease in pH when using KCl solution is due to the exchange of H⁺ and Al³⁺ ions from soil colloids into the solution, resulting in increased soil acidity. This condition can reduce nutrient availability, suppress microbial activity, and potentially lead to toxicity in plants if not properly managed. Therefore, soil pH management through liming is necessary to achieve optimal conditions for plant growth.

Abstract

The palm oil industry plays a vital role in the Indonesian economy, with palm oil (CPO) and palm kernel (PKO) yields as indicators of processing efficiency. This study aims to analyze the yield of CPO and PKO at 30 ton/hour PKS through a quantitative approach with field methods and laboratory tests. Raw and boiled Fresh Fruit Bunch (FFB) samples were taken from 30 ton/hour PKS in Langkat Regency, North Sumatra, then analyzed using material balance, moisture content, oil extraction (soxhletation), and kernel separation. The results showed that the average CPO yield on raw FFB was higher (32.12%) than that on boiled FFB (23.94%), while the PKO yield on boiled FFB (7.74%) was superior to that on raw FFB (3.84%). Factors such as fruit maturity, sterilization process, and extraction efficiency have a significant effect on yield. The findings recommend optimizing the quality of raw materials and processing processes to increase productivity. This study provides a scientific basis for mill in performance evaluation and yield improvement strategies

Abstract

Tanah merupakan salah satu media yang sangat penting bagi tumbuhan. Tanaman dapat tumbuh di beberapa tempat seperti di tanah gambut, tanah salin, dan tanah pasang surut yang mana tanah tersebut digolongkan sebagai lahan marginal yang memiliki karakteristik fisik dan kimia tanah yang secara langsung mempengaruhi tingkat kesuburan tanah. Tanah sebagai sumberdaya alam yang dipergunakan untuk kelangsungan hidup manusia, hewan maupun tumbuhan, tentu memberikan dampak terhadap kualitas tanah. Penggunaan tanah menjadi lahan pertanian, pemukiman maupun perkebunan tentu mendapatkan perlakuan yang berbeda-beda dari lingkungannya yang dalam hal ini dimungkinkan mempengaruhi reaksi tanah. Penelitian ini bertujuan untuk memberikan informasi reaksi tanah akibat perlakuan lingkungan yang berbeda. Penelitian ini merupakan penelitian deskriptif, reaksi tanah diamati dari pH tanah yang diambil dari dari beberapa lokasi. Metode pada penelitian ini meliputi pengumpulan sampel tanah dan penetapan pH tanah dengan cara elektrometri yang menggunakan alat pH meter. Hasil penelitian menunjukkan bahwa pH tanah vegetasi 6,2; pH tanah bakaran 7,8; pH tanah sawah 5,8; pH tanah organik 6,4; pH tanah pantai 6,2 dengan rentang kriteria pH sedang hingga tinggi dengan reaksi agak masam hingga agak alkalis.

Abstract

A study on the manufacture of bacterial cellulose IPN hydrogel crosslinked poly acrylic acid using the MBA crosslinker. This study aims to characterize and observe the reaction to form bacterial cellulose-based hydrogel IPN. The BC-g-PAA was characterized by the degree of cross-linking, swelling ratio, and FTIR analysis. The results of this study found predictions of the reaction process for the formation of IPN Hydrogel in several process stages, namely 1) The polymerization process of bacterial cellulose chains that form cross-linked networks independently, 2) The process of cross-linking Acrylate monomers with MBA crosslinkers in three steps, i.e. initiation, propagation and termination, 3) Reaction process Formation of IPN network. The results of the characterization test for the degree of crosslinking were 54.55%; Swelling ratio of 1631.25%. FTIR analysis shows that there is a peak that identifies the occurrence of crosslinking

Abstract

Chitosan, a natural polysaccharide obtained through the deacetylation of chitin, exhibits unique properties that make it a potential material for various applications, including agriculture. This study aims to examine the characteristics of chitosan derived from Black Soldier Fly (BSF) pupa shells and its role as a crosslinking agent in polymer-based hydrogel synthesis for slow-release fertilizers. Chitosan was isolated through chemical processes, including demineralization, deproteinization, and deacetylation. Characterization was conducted using FTIR, XRD, SEM, TEM, and TGA. The results revealed that chitosan from BSF pupa shells has a degree of deacetylation of 83%, a semi-crystalline and slightly amorphous structure, pores that enhance water absorption capacity, and high thermal stability. These properties make chitosan an effective crosslinking agent, improving hydrogel stability and extending nutrient release duration. These findings demonstrate the potential of chitosan as an innovative material for hydrogel applications in sustainable agriculture.
