Abstract

Limbah cair yang dihasilkan oleh pabrik kelapa sawit, atau Palm Oil Mill Effluent (POME), umumnya dianggap sebagai limbah yang berbahaya. Terdapat beberapa parameter yang bisa diuji pada limbah cair pabrik kelapa sawit seperti pH, Total Solid dan Oil and Grease. Salah satu upaya untuk dapat mengurangi tingkat pencemaran pada limbah cair pabrik kelapa sawit adalah dengan cara biodegradasi menggunakan mikroorganisme seperti Microbe-Lift. Perlu dilakukan pengujian untuk mengetahui pengaruh konsentrasi Microbe-Lift dan waktu tinggal terhadap Nilai pH, Total Solid, dan Oil and Grease Pada Limbah Cair Pabrik Kelapa Sawit. Dimasukkan 500 ml sampel limbah pada 6  gelas piala dan ditambahkan masing- masing Mikrobe-Lift kedalam sampel 6 gelas piala tersebut dengan konsentrasi 0,00%; 0,10%; 0,20%; 0,30%; 0,40%; dan 0,50%. Kemudian diukur pH dengan mengunakan pH meter, Total Solid dan Oil and Grease dengan metode gravimetri. Pengujian ini dilakukan sampai hari ke-15. hasil pengukuran pH menunjukan kenaikan  hingga hari ke -15 disebabkan penguraian asam organik oleh Mikrobe-Lift. Setiap hari terjadi penurunan nilai Total Solid dan Oil and Grease sampai hari ke-15. Nilai Total Solid dan Oil and Grease sebelum penambahan Microbe-Lift adalah 6850 mg/L dan 15040 mg/L. Setelah 15 hari diperoleh Nilai Total Solid dan Oil and Grease paling rendah pada konsentrasi Microbe-Lift 0,50% sebesar 3900 mg/L dan 2900 mg/L, terjadi penurunan masing – masing 43% dan 80,71%. Dapat disimpulkan bahwa semakin tinggi konsentrasi Mikrobe-Lift dan semakin lama waktu tinggal maka  pH larutan akan semakin tinggi dan nilai Total Solid dan Oil and Grease limbah cair pabrik kelapa sawit akan semakin berkurang.

Abstract

Agricultural extension is undeniably very important for farmers in improving rice cultivation because it provides them with the information and activities needed to increase rice productivity and farmers' food independence. This study aims to analyze the level of competence of extension workers in improving food security. The competencies possessed by extension workers in this regard consist of knowledge, skills, and attitudes. Food security in this study is examined from the aspects of availability, access, and safety quality. The research was conducted in Kuantan Singingi District, Riau Province, which has high rice production and adequate agricultural extension services for rice cultivation. The sample was selected using the purposive sampling method, resulting in fifty-eight extension workers being chosen. The Spearman Rank correlation test was used to assess the relationship between the competence of extension workers and food security in Kuantan Singingi Regency. The results reveal that all variables of the extension workers' competence (knowledge, skills, and attitudes) have a significant relationship with the food security of farmers, in terms of food availability, access, and safety quality. Extension workers indirectly play a crucial role in enhancing the food security of farmers’ households by sharing information and innovations that help improve rice production and overall household food security. Future researchers can develop sustainable, professional models and technology-based training modules to further improve the competence of extension workers.

Abstract

In this study, a modified polyethylene glycol modified cellulose acetate membrane was made. Cellulose acetate was synthesized from cocoa husk waste (Theobroma cacao L) with several steps, namely isolation of alpha cellulose from cocoa husk waste, synthesis of cellulose acetate from alpha cellulose, preparation of 10% cellulose acetate membrane with the addition of polyethylene glycol 0, 5, 10, 15, 20 & 25% . From the results of the research, it was found that the FT-IR analysis of -cellulose from cocoa shells showed an absorption peak at wave numbers between 3400 – 3500 cm-1 which indicated the presence of O-H stretch groups. At wave numbers 2800-2900 cm-1 indicates C-H stretching, then it can be seen at wave numbers 1160 cm-1 indicates C-O-C stretching, and at 1035-1060 cm-1 indicates C-O stretching. In the fingerprint area, we found absorption peaks at wave numbers around 1300 cm-1 which indicated the presence of C-H bending and around 1400 cm-1 indicating the presence of CH2 bending. The cellulose acetate obtained is white and smooth compared to alpha cellulose. At the membrane preparation stage, the results of the insoluble cellulose acetate & PEG using acetone as a solvent. So it is necessary to do a solubility test and find a suitable solvent to form polyethylene glycol modified cellulose acetate membrane for Pb metal ion filtration.

Abstract

Telah dilakukan kegiatan Pengabdian Kepada Masyarakat (PKM) di Sirambang, Cubadak Air Utara, Kota Pariaman, Provinsi Sumatra Barat dengan judul "Pembuatan Cokelat Batang Melalui Proses Fermentasi dari Biji Buah Kakao." Mitra kegiatan ini adalah kelompok usaha petani Kakao, melibatkan 20 peserta petani dan 7 instruktur dari Politeknik ATI Padang. Saat ini, petani di daerah tersebut masih terbatas dalam mengembangkan hasil pertanian buah kakao menjadi produk pangan. Mereka cenderung hanya menjual biji buah kakao kering kepada agen pengumpul hasil bumi. Oleh karena itu, diperlukan pelatihan untuk mengajarkan cara mengolah biji buah kakao menjadi produk pangan berupa cokelat batang yang memiliki daya tarik tinggi di pasar konsumen, sehingga dapat meningkatkan perekonomian masyarakat. Proses pembuatan cokelat batang melalui fermentasi biji buah kakao dimulai dengan memasukkan biji kakao ke dalam alat fermentor dan mengfermentasinya selama 7 hari. Hasil fermentasi kemudian dijemur di bawah sinar matahari hingga kering, lalu biji kakao disangrai dalam kuali hingga benar-benar kering. Biji kakao yang telah bersih dimasukkan ke dalam blender dan dicampur dengan minyak goreng, susu, dan gula dalam perbandingan 1:1:1:1. Adonan di-blender hingga halus, membentuk pasta cokelat, yang kemudian dicetak dalam cetakan cokelat dan dibekukan dalam freezer. Cokelat batang yang telah terbentuk dikemas menggunakan aluminium foil dan dibungkus dengan kemasan cokelat. Kegiatan PKM dilaksanakan dengan baik dan lancar, diharapkan memberikan wawasan kepada mitra mengenai proses pembuatan cokelat batang melalui fermentasi biji buah kakao. Semoga hasil ini dapat digunakan untuk memenuhi kebutuhan sehari-hari serta menjadi sumber penghasilan tambahan bagi masyarakat.

Abstract

Shortening is a solid plastic fat product that is widely used as a raw material in the production of food products such as biscuits, cakes, bread, and pastries. PT X produces shortening from the interesterification reaction of Refined, Bleached and Deodorized Palm Oil. (RBDPO). In the shortening production process using the interesterification method, it will be influenced by the amount of catalyst added and the heating time. The objective of this research is to analyze the effect of the amount of sodium methoxide catalyst and heating time on the interesterification process of RBDPO on the quality of shortening products. By considering the parameters of Solid Fat Content (SFC) and Slip Melting Point (SMP), an optimal method can be developed to improve the quality and stability of the shortening product. The variations of sodium methoxide catalyst used are concentrations of 0.050%; 0.100%; 0.125%; 0.25%; 0.375%; 0.500%, while the variations in heating time are 50 minutes, 40 minutes, and 30 minutes. The results of the research conducted show that the interesterification process of RBDPO into a shortening product with very good quality is achieved by using sodium methoxide catalyst with a concentration of 0.250% and a heating time of 40 minutes, in accordance with the standards set by PT X for Solid Fat Content (SFC) and Slip Melting Point. (SMP).

Abstract

Webinars and surveys have been widely used. Popular applications such as ezTalks, Zoom, Demio, Google Meet, LiveStorm have been used in seminars and online meetings. For every webinar activity, the organizers often carry out survey activities to see feedback from participants, google forms applications, survey monkeys, typeforms, zoho surveys, and gizmo surveys are used to see responses from all participants. In addition, several organizers also gave appreciation in the form of certificates. However, the management of many webinars is often an obstacle to seeing the results of each activity and the participants who take part in the activity. Although the use of google forms has been very good and effective, the lack of features in the management of webinar activities is a problem in itself in making reports in a short time. Therefore, we need a service application that can assist in the management of webinar activities and has survey features from registration, attendance to certificates. Where later application users (organizations, committees) can fill out webinar activities and can propose surveys for each activity carried out. In software development, Agile Development Methods (ASD) are used, Event Management System for Webinars and Survey applications that the researchers built using CodeIgniter and React-Js. In the test, we plan the data analysis to be divided into three parts, namely Demographic Analysis Results, Reliability Test Results Analysis, Validity, and Data Processing Analysis. Analysis Data processing includes Importance-Performance Analysis (IPA). So far, webinar and survey management applications have completely fulfilled needs such as making a number of questions in the form of multimedia and sharing research data, but webinar management applications with survey services in an application have not been carried out. It is hoped that the development of research on webinar and survey management applications will produce more visualitative applications and be able to manage webinar activities and reporting related to surveys, reporting participants for each activity carried out. Based on the results of the Importance Performance Analysis, it is known that the average value of the level of expectation or importance for usability is 3.97, and the average value for the level of performance is 3.68. the average value of the level of expectation or importance for information quality is 4.07, and the average value for the level of performance is 3.70. the average value of the level of expectation or importance for service interaction is 3.94, and the average value for the level of performance is 3.71.
