Abstract

Nanocellulose is a type of cellulose that is being widely developed to replace petroleum-based polymers. This material possesses biocompatible properties, is abundant in nature, and is eco-friendly due to its biodegradability, sustainability, and non-toxic nature. Various nanocellulose synthesis methods are employed, including acid hydrolysis, alkaline, mechanical and biological treatments, as well as ionic liquid and deep eutectic solvent methods. The choice of synthesis method greatly influences the particle size and crystallinity of the resulting nanocellulose; hence further investigation is needed to determine the effectiveness of these methods. Nanocellulose finds applications in various fields, such as films, polymers, cosmetics, medical fuels, and energy storage. Among the different nanocellulose synthesis methods, ionic liquid and deep eutectic solvent (DES) methods have environmentally safe waste with better temperature, time, and diameter control compared to other methods. However, the DES method is currently preferred over the ionic liquid method due to the possibility of separating the lignin waste from the solvent.

Abstract

The main purpose of this study is to find the effect of budget deficit with foreign loans as source of funding on inflation and economic growth. This study focuses on transmission mechanism of budget deficit funding effects on inflation and economic growth. We use a specific simultaneous macroeconomic model which includes 17 behavioral equations and 18 identity equations with 6 blocks in this study, Two Stage least Square (TSLS) method is employed to estimate the behavioral equations in the model. This study use Indonesia secondary economic data from 1970 to 2003. Econometric tests are performed to produce BLUE estimator. This study also use stochastic simulation with 10.000 replications to simulate policy. The results show that using foreign loan to fund budget deficit increases both economic growth and inflation. This result is also supported by the simulation results which show that increase in the proceeds of new foreign loan increases reserves which in turn increase primary money/money supply/monetary base. Interaction of monetary base with money multiplier then increases price level. Increase in capital inflow from increase in foreign loan in reases government spending which also increases government spending. Increases in the government spending then add to government capital stock so that economic growth also increases.

Abstract

Arenga palm flour–producing regions face significant challenges in managing solid waste, particularly in Daleman Village, Klaten, Central Java. Home-scale industries generate onggok aren, a cellulose-rich residue consisting of pulp and coarse fibers produced in large quantities. However, in practice, this waste is often discharged directly into rivers, contributing to water and environmental pollution. Most areas of Daleman Village are agricultural lands that typically require fertilizers to maintain soil fertility, which encourages further exploration of the potential use of onggok aren waste. One promising utilization is as a raw material for compost fertilizer that is both efficient and affordable. The composting process is carried out using a simple method with the aid of the EM4 bioactivator and molasses to accelerate the decomposition of organic materials. The activator mixture is applied in a specific ratio of 1 part EM4, 1 part molasses, and 10 parts water. Utilizing onggok aren waste as compost fertilizer not only addresses the issue of waste accumulation but also enhances the value of natural resources and reduces dependence on chemical fertilizers.

Abstract

ABSTRAK. Kabupaten Boyolali memiliki jumlah penduduk tertinggi kedua di eks-Karesidenan Surakarta sehingga limbah cair domestik yang dihasilkan juga tinggi. Hal ini mendorong upaya pengelolaan limbah domestik menggunakan SANFAB ST 600. Penelitian ini bertujuan untuk mengetahui efektivitas kinerja IPAL Individual SANFAB ST 600 setelah diberi perlakuan dengan Anaerobic Granule Bacteria. SANFAB ST 600 memiliki volume 600 L dan berkapasitas 1-4 orang. Air limbah rumah tangga yang dialirkan ke inlet ST akan menuju ke settler, selanjutnya mengalir secara upstream dalam unit Anaerobic Filter dan terjadi penguraian zat pencemar oleh bakteri anaerobik. Pengambilan sampel dilakukan pada dua rumah di Dusun Karangmojo, Kabupaten Boyolali. Sampel diuji di BLKK Yogyakarta untuk parameter TSS, COD, BOD, konsentrasi Amonia, pH, dan ORP. Pada minggu ketiga di Rumah Bapak Wahyudi, karakteristik outlet ST memiliki nilai TSS 25,5 mg/L, Amonia 0,255 mg/L, BOD 25,01 mg/L, dan COD 47,92 mg/L sehingga sudah sesuai baku mutu. Dari hasil uji dilakukan perhitungan efektivitas pengolahan TSS, BOD, dan COD dengan cara menghitung selisih konstanta inlet dan outlet dibagi dengan konstanta inlet serta perhitungan rasio BOD/COD dengan membagi kadar COD dan BOD setiap sampel. Dari sumber limbah WC dan kamar mandi (Rumah Bapak Wahyudi) bakteri bekerja lebih efektif dibanding sumber limbah WC (Rumah Bapak Somowirejo) dengan efisiensi lebih dari 80% pada minggu ketiga penambahan bakteri.  Kata kunci: Anaerobic Granule Bacteria, Efisiensi, Limbah Domestik, IPAL ST 600 ABSTRACT. Boyolali Regency has the second highest population in the residence of Surakarta so the domestic wastewater generation is also high. This led to the management of domestic wastewater using Individual WWTP SANFAB ST 600. This study aims to determine the effectiveness of Individual WWTP SANFAB ST 600 after being treated with Anaerobic Granule Bacteria. The SANFAB ST 600 has a volume of 600 L and a capacity of 1-4 people. Domestic wastewater that flows into the ST inlet will go to the settler, then flows upstream into the Anaerobic Filter unit and decomposed by anaerobic bacteria. Sampling was carried out at two houses in Karangmojo, Boyolali Regency. Samples were tested at BLKK Yogyakarta for parameters of TSS, COD, BOD, Ammonia concentration, pH, and ORP. In the third week at Wahyudi's house, the characteristics of the ST outlet had a value of TSS 25.5 mg/L, Ammonia 0.255 mg/L, BOD 25.01 mg/L, and COD 47.92 mg/L so it already suitable with the standard. From the test results, the effectiveness of TSS, BOD, and COD reduction is calculated by the difference between the inlet and outlet constants divided by the inlet constant and also calculating the BOD/COD ratio by dividing the COD and BOD levels of each sample. From the source of WC and bathroom waste (Mr. Wahyudi's House) the bacteria worked more effectively than the WC source (Mr. Somowirejo's House) with an efficiency of more than 80% in the third week after bacteria addition.Keywords: Anaerobic Granule Bacteria, Efficiency, Domestic Wastewater, IPAL ST 600

Abstract

ABSTRAK. Konsumsi energi pada sektor transportasi di Indonesia sangat besar dikarenakan penggunaan BBM yang sangat besar. Besarnya proporsi penggunaan BBM untuk transportasi juga diikuti dengan besarnya subsidi pemerintah untuk BBM. Data sepanjang tahun 2010-2020 menunjukkan realisasi subsidi BBM selalu lebih besar dibandingkan dengan yang dianggarkan. Sehingga perlunya alternatif untuk mengurangi konsumsi BBM pada sektor transportasi. Dari sisi teknis peluang penggunaan bioetanol generasi 1 (G1) berbahan molasses mudah di aplikasikan karena proses yang sederhana. Dari analisis ekonomi terlihaat bahawa projek ini layak dilakukan ketika NPV dan DCFROR bernilai positif, sehingga saat harga molasses 1.500,00/ Kg dan harga bioetanol 15.000,00/ liter projek ini layak dilakukan, begitu juga ketika harga molasses 2.061,00/ Kg dan harga bioetanol 16.000,00/ liter serta ketika harga molasses 2.061,00/ Kg dan harga bioetanol 15.000,00/ liter, namun ketika harga molasses 2.061,00/ Kg dan harga bioetanol 12.113,00/ liter projek ini tidak layak dilakukan karena NPV dan DCFROR bernilai negatif. Dari hasil simulasi tersebut diketahui bahwa harga molases dan bioetanol sangat berpengaruh terhadap realisasi substitusi BBM dengan bioetanol, selain itu ketersedian bahan baku yaitu molasses juga perlu diperhatikan untuk menjaga kontinuitas proses. Kata Kunci: Bahan Bakar, Bioetanol, Ekonomi, Transportasi  ABSTRACT. Energy consumption in the transportation sector in Indonesia is very large due to the very large use of fuel. A large proportion of the use of fuel for transportation is also followed by the number of government subsidies for fuel. Data throughout 2010-2020 show that the realization of fuel subsidies is always higher than the budgeted one. So the need for alternatives to reduce fuel consumption in the transportation sector. From a technical point of view, the opportunity to use bioethanol generation 1 (G1) which is made from molasses is easy to apply because of the simple process. From the economic analysis, it can be seen that this project is feasible when the NPV and DCFROR are positive, so when the molasses price is 1.500,00/Kg and the bioethanol price is 15,000.00/liter this project is feasible, as well as when the molasses price is 2.061,00/Kg and the price of molasses is 2.061,00/Kg. bioethanol 16.000,00/liter and when the price of molasses is 2.061,00/Kg and the price of bioethanol is 15.000,00/liter, but when the price of molasses is 2.061,00/Kg and the price of bioethanol is 12.113,00/liter this project is not feasible because of NPV and DCFROR have a negative value. From the simulation results, it is known that the price of molasses and bioethanol is very influential on the realization of the substitution of fuel with bioethanol, the availability of raw materials or molasses also needs to be considered to maintain the continuity of the process.Keywords: Fuel, Bioethanol, Economy, Transportation
