Abstract

Pengabdian pada masyarakat ini bertujuan untuk membantu masyarakat dalam meningkatkan pendapatan, wawasan, pengetahuan dan ketrampilan serta memberikan motivasi akan perubahan perilaku dalam manajemen pengolahan ampas dengan produk susu kedelai menjadi tepung ampas susu kedelai di UKM Susu Kedelai Mamak. Dimana tepung ini nantinya bisa mengganti tepung tapioka yang biasa digunakan UKM ini untuk membuat cemilan-cemilan lain seperti kerupuk. Selama ini ampas industri pembuatan susu kedelai hanya dimanfaatkan sebagai pakan ternak dengan harga yang sangat rendah. Teknologi pembuatan kerupuk dari ampas susu kedelai sangat sederhana, yaitu pengumpulan ampas dari susu kedelai, menyiapkan tepung tapioka dalam hal ini tepung tapioka diganti dengan tepung ampas kedelai, penyedap rasa, dan bawang putih, campurkan bahan-bahan hingga homogen, pengukusan adonan, pemotongan adonan, penjemuran dan penggorengan.

Abstract

Devotion is an activity that is highly expected to be carried out well, because it can improve and add to knowledge and skills. The male students at the Al Quran memorization headquarters are the driving force to open up land that has not been utilized properly. The location of the land for strengthening food security that will be carried out is close to the location of the Al Quran memorization headquarters, making it easier to move to the land location. The beginning of this movement is land preparation or clearing land from undergrowth using tripe, machetes and hoe so that clean land is obtained and ready to be planted. The types of plants that will be planted in this food security strengthening are cassava, sweet potatoes or yams, corn, taro, peanuts and green beans.

Abstract

The grounding system in substations generally uses electrode rods, because electrodes can affect the effectiveness of fault current conduction, so the equipment will be safer. Considering the importance of the grounding system, the installed grounding system must be considered and maintained properly. One of them is the grounding found in Glugur. The main objective of this research is to comprehensively evaluate the substation grounding system by modeling the grounding system at the Glugur Substation using MATLAB graphical user interface (GUI). The grounding resistance follows a grid system with an area of 20×15=300 m² with specific resistance being clay using 100 rod electrodes. From the results of ground resistance simulation modeling using MATLAB GUI, it can be concluded as follows: for a certain resistance value, the number of electrodes for 100 Ωm is 3.55 Ω, for ground resistance with a constant depth and a varying number of 100 electrodes, it is 3.45 Ω, and for. The grounding resistance with a constant and varying number of 1,000 rods is obtained at 2.65 Ω. From these results, the modeling carried out is in accordance with the standards of electricity regulations in Indonesia.

Abstract

Kebisingan adalah salah satu konsekuensi negatif dari meningkatnya penggunaan mesin industri, yang terbagi atas kebisingan rendah, sedang, dan keras. Tujuan penelitian ini adalah untuk menentukan jumlah kebisingan di ruang kerja Fatty Acid Fase2, area paparan kebisingan, dan usulan pengendalian. Menggunakan pendekatan tingkat kebisingan ekuivalen (Leq) dengan alat pengukur Sound Level Meter, pengukuran langsung dilakukan untuk mendapatkan data. Temuan ini menunjukkan bahwa tingkat kebisingan untuk lantai 0 (85,61 dBA), lantai 3 (88,18 dBA) dan lantai 4 (87,73 dB) kegiatan FattyAcid Fase 2 lebih tinggi daripada NAB. Pemberian tanda di tempat-tempat dengan tingkat kebisingan yang berlebihan, briefing keselamatan, penggunaan APD, penggantian bagian mesin yang rusak, dan pelumasan bagian bergerak, serta mengatur ulang penjadwalan maintenance beberapa saran perbaikan yang diusulkan.

Abstract

Jakarta, as a rapidly growing urban area, faces challenges in balancing energy demand with supply while addressing environmental concerns associated with traditional energy sources. Electrical energy production prediction in urban environments like Jakarta is crucial for effective energy management, ensuring stable supply, and promoting sustainable development. The prediction of electrical energy production in Jakarta is critical for ensuring stable and sustainable energy supply. This research proposed the application of the adaptive neuro-fuzzy inference system (ANFIS) as a predictive tool specifically tailored for Jakarta's energy production prediction context. The research methodology used in this study is the ANFIS. Five levels make up the architecture of the ANFIS model: output, normalization, defuzzification, rule evaluation, and fuzzification. The fuzzification layer converts input variables into linguistic terms using membership functions, while the rule evaluation layer calculates the activation strength of each rule based on the input values. The predicted results of Jakarta electrical energy production from 2023 to 2028 are 65,288 GWh and there is an annual increase of 5.25%. The error contained in ANFIS is with a root mean square error (RMSE) value of 0.0001058% and a mean absolute percentage error (MAPE) value of 0.00875%.

Abstract

PT. Permata Hijau Group is a company that continues to develop both upstream and downstream, especially at the product sales level. Oleic acid is one of the expensive products sold among oleochemical processing companies. In producing oleic acid, several large costs were found due to lengthy repairs and the plantation not operating. So methods are needed to increase productivity. Analysis using the objective matrix (OMAX) method is a method that is widely used in analyzing the productivity of a company. The method used is the use of OMAX, including determining criteria, determining performance, determining average productivity values, determining the highest and lowest productivity values, determining realistic productivity values, determining scores and value weights, determining productivity indices and making cause-cause diagrams. consequence (fishbone). The results obtained from applying the objective matrix (OMAX) method include the first being the highest productivity index value in October 2023 of 66.66% and the lowest in September of -64.93%. The second result is that the factors that have the most influence on oleic acid productivity. And the third result is that 6 proposed actions are needed to increase oleic acid productivity

Abstract

This community service aims to help the community increase insight into the use of digital media and ethics in using social media for mothers who are members of the IKBI (Ikatan Keluarga Besar Istri) PTPN III Sei Mangke through outreach. Mothers can innovate to carry out businesses or business activities using internet media and those related to the digital world. Then what the author will discuss in community service is how to respond to technological advances because in the current millennial era it is very vulnerable to cyber crimes and bullying which are currently rampant on every existing social media, in order to earn money. Many content creators/digital artists make viral videos using YouTube media, and of course the aim is to find an audience and earn money. With this, sometimes there are a lot of irregularities, namely: creating fake news/Hoaxes, pitting people against each other, defaming someone's good name through uploaded content. So it is very closely related to the ITE Law, which can lead to criminal acts.
