Abstract

Abstrak. Penggilingan gabah merupakan proses pengolahan gabah kering menjadi beras dengan bantuan mesin yang dikontrol penuh oleh pekerja pada stasiun tertentu. Manusia sebagai pekerja tengah berada pada ruang penggilingan dengan banyak resiko seperti bising dan getaran yang ditimbulkan oleh mesin tersebut dan antropometri yang belum terjamin kesesuaiannya dengan pekerja yang mengoperasikan mesin tersebut sehingga perlu dikaji berdasarkan kajian ergonomika. Penelitian bertujuan untuk menganalisa antropometri mesin dengan pekerja serta lingkungan fisik untuk mengurangi resiko kerja. Metode penelitian menggunakan metode eksperimental yang dikaji langsung pada ruang penggilingan beras di Desa Batu Putik Lombok Timur. Parameter yang dikaji yaitu antropometri, tingkat kebisingan, getaran mekanis, suhu dan tingkat pencahayaan. Data hasil penelitian dianlisis menggunakan matematika sederhana dengan bantuan mikrosoft excel kemudian dibandingankan dengan Nilai Ambang Batas (NAB) pada setiap parameter. Hasil penelitian menunjukkan bahwa antropometri pada 3 stasiun yang dikaji yaitu stasiun pertama tempat gabah dimasukkan berada 200 cm artinya hopper tersebut berada di atas kepala operator, stasiun kedua output gabah pecah 50% memiliki ketinggian 92 cm dan stasiun ketiga yaitu output beras bersih siap untuk dikemas memiliki tinggi 92 cm. Sedangkan hasil analisis dari lingkungan fisik menunjukkan bahwa suhu di atas NAB dan pecahayaan di bawah NAB, sedangkan getaran mekanis dan tingkat kebisingan berada di atas Nilai Ambang Batas NAB. Sehingga dapat disimpulkan bahwa ruang produksi penggilingan gabah dapat dikatakan belum memenuhi standar ergonomika.Anthropometric and Physical Environmental Analysis of Grain Milling Rooms to Reduce Work RisksAbstract. Grain milling is the process of processing dry grain into rice with the help of machines that are fully controlled by workers at certain stations. Humans as workers are in the milling room with many risks such as noise and vibrations caused by the machine and anthropometers that are not yet guaranteed to be suitable for the workers operating the machine so this needs to be studied based on ergonomics studies. The research aims to analyze the anthropometry of machines and workers and the physical environment to reduce work risks. The research method used experimental methods which were studied directly in the rice milling room in Batu Putik Village, East Lombok. The parameters studied are anthropometry, noise level, mechanical vibration, temperature and lighting level. The research data was analyzed using simple mathematics with the help of Microsoft Excel and then compared with the threshold value (NAB) for each parameter. The results of the research show that the anthropometry at the 3 stations studied, namely the first station where the grain is inserted is 2 meters, meaning the hopper is above the operator's head, the second station, the output of 50% broken grain has a height of 92 cm and the third station, namely the output of clean rice ready to be packaged, has a height of 92 cm. cm. Meanwhile, the results of analysis of the physical environment show that the temperature is above NAB and lighting is below NAB, while mechanical vibrations and noise levels are above the threshold value NAB. So it can be concluded that the grain milling production room can be said to not meet ergonomic standard.

Abstract

Abstrak. Sumber energi terbarukan (biogas) merupakan jenis sumber energi yang bersifat ramah dan tidak mencemari lingkungan. Proses pembuatan biogas berasal dari dekomposisi bahan organik secara anaerob (tanpa udara). Tujuan dilakukannya penelitian ini adalah untuk mengetahui pengaruh berbagai jenis limbah organik terhadap suhu pada pembentukan gas metan (CH4) dan karbon dioksida (CO2) pada biogas. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan yaitu P1 dengan menggunakan limbah ampas tahu sebanyak 4 kg dan air 4 liter, P2 menggunakan kotoran sapi sebanyak 4 kg dan air 4 liter, P3 menggunakan limbah pasar sebanyak 4 kg dan 4 liter air dan P4 menggunakan campuran limbah ampas tahu, kotoran sapi dan limbah pasar sebanyak 4 kg dan air 4 liter. Data hasil pengamatan dianalisa menggunakan ANOVA pada taraf nyata 0,05 (5%). Apabila antar perlakuan terdapat perbedaan yang nyata maka dilakukan uji lanjut BNJ (Uji Beda Nyata Jujur) pada taraf nyata 0,05 (5%). Hasil penelitian menunjukkan bahwa Karbon dioksida (CO2) yang terukur pada pembuatan biogas tertinggi yaitu pada perlakuan bahan baku limbah ampas tahu sebesar 4801,7222 ppm dan yang terkecil pada perlakuan bahan baku kotoran sapi sebesar 2177,417 ppm. Gas metan (CH4) pada pembuatan biogas tertinggi terukur pada perlakuan dengan menggunakan bahan baku kotoran sapi yaitu sebesar 6442 mol dan yang terkecil pada perlakuan dengan bahan baku limbah ampas tahu sebesar 340,25 mol. Sehingga dapat disimpulkan bahwa kandungan biogas terbaik ditemukan pada limbah organik kotoran sapi dengan kandungan CH4 tertinggi sebesar 6442 mol.Analysis of Carbon Dioxide and Methane Gas Content in Making Biogas From Organic WasteAbstract. Organic waste with unlimited sources and high volumes can cause environmental pollution, so optimal processing is needed. Processing that is considered capable of accommodating large-scale processing and whose output has high economic value is biogas. The manufacturing process uses an anaerobic fermentation method using a technology called a digester. The research aims to see the effect of different types of organic waste on the content of carbon dioxide and methane gas. The research design used a Completely Randomized Design (CRD) consisting of four treatments with 3 replications. The treatment in question is T1 with tofu dregs waste with water, T2 with cow dung plus water, T3 with market waste plus water, and T4 with a mixture of tofu dregs, cow dung and market waste with water. The research data were analyzed using ANOVA at a significance level of 0.05 (5%) with the help of SPSS. If significant data is found, a BNJ test with a real level of 5% is carried out. The results of the research showed that the highest carbon dioxide (CO2) content in tofu waste was 4801.72 ppm and the lowest was in cow dung at 2177.42 ppm, while the formation of methane gas (CH4) was highest in cow dung waste, namely 6742.12 mol and the lowest in waste. tofu dregs amounted to 352.65 mol. So it can be concluded that the best biogas content is found in cow dung organic waste with the highest CH4 content of 6742.12 mol

Abstract

A country's development progress can be measured by good economic growth. If economic growth experiences rapid growth, it will usually trigger price increases. The occurrence of an uncontrolled increase in the price of goods or services for the needs of the community can cause inflation. inflation rate for a country is an inflation rate that has a low and stable value. One alternative is to provide an overview of the inflation in Indonesia by using forecasting analysis techniques. In this study, inflation forecasting analysis in Indonesia was carried out using the ANN Backpropagation and ARMA methods. The purpose of this research is to compare the performance results of the two methods and look at the best method for forecasting results. Based on the results of the analysis with the ANN Backpropagation method, the best network architecture model was ANN(7-4-1) using an epoch value of 400 and a learning rate of 0,1 with a value of MSE = 0,0112 and RMSE = 0,1065. While the results of the analysis using the ARMA method, the best model was obtained, namely ARMA(2,0,1) with the value MSE = 0,0648 and RMSE = 0,2545. So that the most optimal method used to predict inflation for the next period is the ANN Backpropagation method because it has a smaller error value. From this model, the results of forecasting inflation rates for the months of May to December 2022 are also obtained with a range of 0,01% to 0,5%.

Abstract

Fossil energy reserves to date are dwindling inversely proportional to the amount of consumption. So to overcome this problem, alternative energy is needed, one of which is biogas which is sourced from organic waste. The biogas production process has so far experienced many obstacles so that the formation of pressure has not been optimal. The aim of the research was to create a model to see the magnitude of the influence of humidity and temperature on the pressure of the biogas produced. The method used is multiple linear regression with the following stages, identifying variables, testing classical assumptions, model building, and model goodness. Based on the results of the analysis, the model Y ̂=17.029-0.042X_1+3.480X_2 is obtained. Simultaneous test results show that simultaneously humidity and temperature have a significant effect because the sig is 0.000<α(0.05). The results of the partial test (T-Test) of each variable also showed significant results on biogas pressure because the sig was 0.000<α(0.05). The coefficient of determination of 0.8180 means that humidity and temperature variables affect the formation of biogas pressure by 81.80% and the rest is influenced by other factors such us pH, C/NRatio, starter, and so on.

Abstract

Abstrak bahasa Inggris: Cassava tape is originally local food from Indonesia. This product is fermented resulting different sensory properties. The application of various packaging to wrap cassava when making tape; however, there is no research, which compares the effect of several packaging to organoleptic properties of cassava tape. This research aims to figure out the effect of different packaging to organoleptic characteristic of cassava tape. The result was designed using completely randomized design (RAL) and analysed by variant analysis (Anova). Duncan Multiple Range Test (DMRT )was used to test significant results. According to the analysis, there was a significant difference in different packaging used to the organoleptic perception of cassava tape, especially in flavor, taste, sweetness level, and texture. There was a strong alcoholic flavor, a very liked taste, high sweetness level, and soft texture. The use of plastic jar tends to trigger no alcoholic flavor, unliked taste, no sweetness, and hard texture. When using a plastic bag it had almost similar flavor, color and taste to the tape wrapped with banana leave; however, it has less sweetness and less soft texture. In conclusion, based on the result it is recommended to pack the cassava with banana leave to obtain greater sensory properties according to what consumers’ desire.

Abstract

This study investigates the persistent phenomenon of Ganti Menteri, Ganti Kurikulum (Change Minister, Change Curriculum) in Indonesian education, analyzing it not merely as administrative inconsistency but as a structural pathology where curriculum policy functions as a tool for political legitimacy. Utilizing a qualitative library research method underpinned by Michel Foucault’s genealogical analysis and institutional trauma theory, this research traces the trajectory of curriculum reforms from the Old Order (1947) to the current Kurikulum Merdeka. The findings reveal that curriculum changes are frequently driven by legitimacy through negation a political logic where new ministers validate their authority by pathologizing predecessor policies and sustained by a proyek economy that incentivizes frequent material procurement. This cycle of discontinuity inflicts systemic trauma on the educational ecosystem, manifested as chronic teacher reform fatigue, the erasure of institutional memory, and administrative paralysis. The study concludes that unless curriculum development is decoupled from the five-year political cycle through a legally binding Grand Design and an independent oversight commission, Indonesian education will remain trapped in a state of perpetual, superficial reinvention.
