Abstract

Research has been done on rice husks. Rice husk is carried out in the carbonization process which is then carried out by the activation process. Furthermore, from the activation process, the impregnation process is carried out. Characterization using a thermo gravimetric analyzer (TGA) showed that the residue of impregnation of rice husk activated carbon was 61.83% and rice husk activated carbon was 89.72%.

Abstract

HIRARC is a hazard identification, risk assessment, and risk control process, which identifies potential hazards in ordinary and unusual business activities, including an assessment of potential hazards and strategies to mitigate risks. Work accidents can occur due to actions, human conditions, and mechanical factors. The research method is data analysis in the work process and container filling, then risk control of each process. The data in the hazard and risk assessment is a qualitative analysis in AS/NZS 4360:2004. 53 sources of danger were identified from 12 stages of work. The results of the risk evaluation showed a low-risk level of 32% with 18 sources of danger, a moderate risk level of 28% with 16 sources of danger, a high-risk level of 16% with 9 sources of danger, and an extreme risk level of 24% with 14 sources of danger. This study concludes that in the dismantling process there are four stages of work, namely starting from the opening of the hatch (3 sources of danger), stevedoring (20 sources of danger), cargodoring (4 sources of danger), and delivery (2 sources of danger). In the loading process, there are four stages of work, starting from receiving (6 sources of danger), cargodoring (4 sources of danger).

Abstract

AbstractThis study intends to evaluate the degree of oil losses in CPO processing at the "x" business unit of the PTPN IV palm oil mill. You may examine the amount of oil loss that takes place as well as the causes of the oil loss using the seven tools technique. In order to ensure that CPO production consistently results in the best goods and preserves the quality of CPO, the PTPN IV "x" factory constantly works to ensure that oil losses that do occur are always within the company's norm threshold. As can be seen from the daily losses data, which indicates that the degree of oil loss is still beyond the company's norm threshold, the research findings indicate that oil loss throughout the CPO processing process is still quite high. The histogram shows that the Boiled Water and Final Drab stations experienced the highest average oil loss, with deviations from the average of 0.24% and 0.03%, respectively. The pressure is outside the control limits in the 20th data on the control chart at the Ampas station, with a UCL of 4.86% and an LCL of 3.07%. Oil losses are a result of four factors: machinery, human resources, raw materials, and methods. Starting with the most important, the causes of oil losses are human resources, followed by raw materials, machines, and processes. Keywords:Oil losses, Crude Palm Oil, Seven tools.  AbstrakTujuan dari penelitian ini adalah untuk menganalisis seberapa besar tingkat kehilangan minyak (oil losses) pada pengolahan CPO dipabrik kelapa sawit PTPN IV unit usaha “x”. Dengan metode seven tools dapat menganalisis seberapa besar tingkat kehilangan minyak yang terjadi serta dapat menganalisis faktor penyebab dari kehilangan minyak tersebut. Dalam proses produksinya pabrik PTPN IV “x” selalu berusaha agar kehilangan minyak yang terjadi selalu dibawa batas ambang norma perusahaan agar  produksi CPO selalu menghasilkan produk yang terbaik dan menjaga kualitas mutu CPO. Hasil penelitian ini menunjukan bahwa kehilangan minyak pada saat proses pengolahan CPO masi sangat tinggi, hal tersebut dapat dilihat dari data losses harian yang menunujukan bahwa tingkat kehilangan minyak masi berada diatas batas ambang norma perusahaan. Dengan histogram dapat diketahui rata-rata kehilangan minyak paling tinggi terjadi pada stasiun Air rebusan dan Drab akhir dengan selisih terhadap norma 0,24% dan 0,03 %. Pada peta kendali distasiun Ampas pressan berada diluar batas pengendalian pada data ke 20 sebesar 4,93 % dengan UCL 4,86 % dan LCL 3,07 %. Faktor penyebab kehilangn oil losses terdapat 4 faktor yaitu Mesin, SDM, Bahan Baku dan Metode. Penyebab kehilangan oil losses mulai dari yang paling dominan adalah SDM, bahan baku, mesin dan terakhir metode. Kata Kunci:                                      Kehilangan minyak, Minyak sawit mentah, Tujuh alat.

Abstract

Pengabdian masyarakat ini dilakukan pada saat covid 19, dimana tujuan dari pengabdian ini menghasilkan prodak yang dapat dikonsumsi anak anak tahfidz yang salah satu manfaatnya untuk mencegah masuk angin. Daya tahan tubuh sangat penting saat ini untuk mencegah dari serangan virus. Dengan berkumpulnya anak anak tahfidz dalam suatu ruangan harapkan semuanya harus terhindar dari serangan virus yang dapat menyebabkan flu dan pilek. Untuk membentengi tubuh agar fit dilakukan pengabdian masyarakat ini, yang akan menghasilkan produk bombon rasa bandrek. Proses pembuatannya yang mudah dan bahan pembuatannya yang murah, namun mendapatkan hasil rasa yang enak serta gampang mengkonsumsinya, membuat anak tahfidz sangat menyukainya. Bahan bandrek untuk menghasilkan bonbon rasa bandrek terdiri dari gula aren, santan kelapa kental, jahe, serai, cengkeh, buah pala dan daun jeruk. Alat yang digunakan untuk menghaluskan bahan digunakan gilingan batu. Prosesnya dimasak dengan menggunakan air dari santan kelapa dengan menggunakan api sedang. Prosesnya diaduk terus sampai mengental dan mengering. Dalam keadaan panas bombon bandrek yang mengering sehingga masih bisa dibentuk, dikemas dalam suatu wadah loyang dan segera dipotong potong kecil kecil yang selanjutnya dibungkus dengan kertas minyak.

Abstract

Food security is a major challenge for Islamic boarding schools (pesantren) with limited resources and agricultural land. This study aims to optimize the use of vacant land to enhance food security at the Markaz Penghafal Al-Qur'an of Yayasan Layar Dakwah. The research methodology includes the application of agricultural techniques such as raised bed construction, selection of superior seeds, and efficient plant maintenance. The results show that utilizing vacant land with appropriate agricultural methods can increase food productivity and reduce dependence on external supplies. Tomato plants demonstrated the highest productivity at 2.25 kg/m², followed by red chili (1.75 kg/m²) and shallots (1.25 kg/m²). Additionally, the involvement of students in agricultural activities provided added benefits in terms of skill development and increased motivation. The novelty of this study lies in the integration of agricultural techniques with the pesantren education system, as well as the implementation of simple agricultural technologies that can be applied sustainably. Therefore, this research offers practical solutions to improve food security in pesantren and empower students in the field of agriculture.

Abstract

Inventory management of raw materials is a crucial aspect in ensuring the smooth production process of the palm oil industry. This study examines the effectiveness of integrating forecasting models and Material Requirement Planning (MRP) to optimize the inventory of Crude Palm Oil (CPO) raw materials at PT Salapian Indo Sawit. The palm oil industry in Indonesia represents about 3.5% of the national Gross Domestic Product (GDP) and provides employment for more than 17 million people. Inaccuracies in raw material inventory management lead to disruptions in the production process and inefficiencies in operational costs. The literature review shows that MRP methods with lot-for-lot techniques have been effectively implemented in various industries, but their application in the palm oil sector is still limited. The objective of this research is to analyze optimal forecasting methods for CPO raw material requirements and evaluate the efficiency of MRP implementation compared to conventional methods. The novelty of this research lies in the integration of forecasting methods (Moving Average and Single Exponential Smoothing) with MRP specifically for the palm oil industry, considering the unique characteristics of the palm oil supply chain. The study uses a descriptive quantitative approach with demand and historical production data from June 2020 to May 2021. The results indicate that the Single Exponential Smoothing method with ?=0.5 provides the best forecasting accuracy (MAPE=0.120; MSE=436.17). Implementing MRP with lot-for-lot techniques results in significant efficiencies, including a reduction in order frequency (26.67%), a reduction in order quantity (7.63%), and a reduction in initial inventory (8.10%). This study concludes that integrating an accurate forecasting model with the MRP system is effective for optimizing CPO raw material inventory and enhancing the operational efficiency of the company.
