Abstract

The courtyard existance that has been recommended in some publication may need to be promoted and hence prioritized on every Rumah sederhana Sehat (RsS) development. In order to support the courtyard promotion initiative, evidence based on research into RsS courtyards’ characteristic that inform the maintenance of optimal indoor thermal comfort, needs to be acquired. This paper examines the issue of the RsS courtyard’s position as one of the factors that is effective in both establishing and maintaining each house’s indoor thermal comfort. The research is conducted with Ansys 14.5 Fluid CFD simulation. The unit model itself is a 9 x 9 m2 unit house. A 3 x 3 m2 courtyard, in 9 different placements, is tested for its effectiveness in maintaining the RsS model’s indoor thermal comfort. Based on the results and the discussion, it can be concluded that there are 5 courtyard positions that provide the RsS houses and their residents with comfortable indoor temperatures. Therefore, these five positional options can be proposed as viable courtyard placements, especially the two positions that show superior performance to the other three acceptable courtyard locations.

Abstract

Biogas production process is an alternative method to reduce dependency on non-renewable fossil-based energy consumption and also can reduce greenhouse gases production both domestically and industrially. The existing biogas technology is suitable to be adapted in small-micro-medium enterprises and domestics, specifically for those who raise cattle. The case study was performed by observation of biogas production with various wastes as feed, namely cow dung, quail manure, and wastewater of tofu production. The study conducted via direct interviews with stake holders and visitations to the instalations. Based on our observation, biogas production from cow dung exhibits the shortest retention time compared to the others, aside from the value of C/N ratio of the biogas feedstocks. The presence of biogas production installations are significantly reducing the energy supplies among the users. Beside as biogas product, the instalations also produce solid and liquid fertilizers as by-products and have relatively high economic value. Socio – engineering problems based on the application of biodigester are also studied.

Abstract

Mathematical modelling on kinetics of batch adsorption of vitamin E separation from palm fatty acid distillate (PFAD) has been set-up and then applied for literature experimental data. Since the sizes of adsorbent particles used are usually relatively small, the concentration in the particles is assumed to be uniform. Hence, the adsorption rate is controlled by the rate of solute mass transfer from the bulk fluid to the surface of particles. In this model, the rate of mass transfer is assumed to be proportional to the concentration deviation from the equilibrium state. Meanwhile, the equilibrium models applied were coefficient distribution, Freundlich, and  Langmuir with  the  values  of  the  parameters obtained from literature data. It turned out that the model set-up can quantitatively describe the experimental kinetics data from literature. The value of mass transfer coefficient per unit adsorbent mass (kca) is obtained by curve fitting. It is also observed that the model proposed quantitatively describes the batch adsorption process well. The three equilibrium models applied are suitable for the mathematical modelling. Adjustment of the values of equilibrium isotherm parameters from literature significantly improves the accuracy of the model.

Abstract

The quality and quantity of cow’s milk produced were determined by the genetic, food, age, milking processing, and the treatment of cattle. The storability of fresh cow's milk tends to be short. Therefore, it is necessary to find ways to extend the life time of fresh cow's milk, one of which is by processing fresh cow's milk into other products, such as milk soap bar. The purpose of this study was to determine the appropriate method of milk soap bar production in home industries capacity and to formulate composition of vegetable oils and fresh cow's milk. The milk soap bar obtained then was analyzed in several laboratory tests such as acidity test (pH), moisture content, free alkaline content, and foam stability. Based on the research, it is turned out that the appropriate method of milk soap bar production was the cold process. The optimum formula is olive oil (11%), coconut oil (22%), palm oil (22%), fresh cow's milk (33%), and NaOH pellets (12% - equivalent to 9.2 N). The free alkaline content will decrease according the curing time. Simpler economic evaluation obtained that the production cost of milk was Rp.6,711.22/package of 80 grams of milk soap bar. Milk soap bar  is sold for Rp. 7,000.00 will provide 87.96% after-tax of ROI, 11.7– month of POT, and 65.31% of BEP.

Abstract

Oryzanol yang terkandung dalam minyak bekatul mempunyai kekuatan antioksidan lebih  tinggi  daripada vitamin E  dan  terbukti  mempunyai efek hipokolesteromik sehingga berguna untuk kesehatan jantung dan pembuluh darah. Metode adsorpsi menggunakan adsorben silika merupakan salah satu metode isolasi oryzanol yang menjanjikan. Keberhasilan proses pemungutan oryzanol sangat ditentukan oleh pemilihan pelarut yang digunakan karena oryzanol merupakan senyawa ester sehingga sifatnya mirip dengan sifat trigliserida minyak bekatul yang ingin dipisahkan darinya. Oleh karena itu perlu ditentukan pemodifikasi pelarut sehingga diperoleh campuran pelarut yang cocok untuk proses tersebut. Modifikasi dilakukan terhadap pelarut utama n-heksana dan pemodifikasi potensial yang digunakan adalah etil asetat, diklorometana, kloroform, dan aseton. Performa campuran pelarut diuji menggunakan metode kromatografi lapis tipis (thin layer chromatography - TLC) menggunakan plat TLC silika gel grade 60. Hasil penelitian menunjukkan  kombinasi  n-heksana/aseton  =  85/15  memberikan  hasil  pemisahan oryzanol terbaik, sedangkan kombinasi    n-heksana/etil asetat = 90/10 patut dipertimbangkan apabila elusi secara gradien dipilih dalam proses pemisahan.

Abstract

Technological advance leads the natural dyes to be eroded by the synthetic one. Synthetic colorant has advantages of salient, more uniform color and more practical use. Meanwhile, the disadvantage of it is much metal content harmful to the environment. The natural colorant is colorant (pigment) derived from plant, animal or mineral sources. The advantage of natural dyes is that it is more environment-friendly because it is not poisonous and safe for health. The disadvantage of it is storage difficulty. When natural dyes in liquid form is stored too long, it will be decomposed easily. For that reason, it should be stored in powder form.The method used to get natural dyes was extraction with a batch manner. The extraction was carried out with basic material-to-solvent ratios of 1:10, 1:7, and 1:5. The basic materials used were mangrove spesies rhizopora stylosa, Soga Tingi, and Indigofera. The best extract was obtained with a ratio of 1:5 for all basic materials. The powder was prepared by feeding the extracting solvent into a spray dryer so that the natural colorant powder was obtained. The application of colorant powder was used at 1 gram/100 ml, 2 gram/100 ml, 2 gram/100 ml, 4 gram/100 ml, and 5 gram/100 ml. The immersing with natural colorant was conducted in 2 conditions: extract and powder are immersing were carried out 5 times with each submerging of 15 minutes and dried. Then, fixation (color-locking) was done to batik. The fixer employed was tunjung (changing the color of batik into the darker one), alum (maintaining the batik’s color), and lime (change batik color into the brighter one). The fixated batik cloth was then examined for its fading against washing using launder meter and against rubbing using crock meter. The result of the examination was analyzed using a staining scale and greyscale. The examination using the staining scale was divided into 2: wet and dry rubbings. From the result of the wet and dry rubbing test, it was obtained the best result with tingi colorant, alum fixer solution, and powder condition. Meanwhile, on the greyscale, it was obtained the best result with tingi colorant, alum fixer, and powder condition. So, it could be concluded that the optimum application of powder to batik cloth was 4 gram/100 ml water and 5 times immersing. The best result of fading resistance against washing and rubbing was tingi with alum fixer and in powder condition.Keywords – extraction, spray dryer, fixation, launderometer, and crockmeter

Abstract

Livestock farming is an important sector in Indonesia, both economically and socially, in every community. The livestock sector supports and supplements the livelihoods of people who spend their days working in the fields. Small and large-scale livestock farming must be accompanied by an understanding of proper animal care and maintenance. Looking at the data and conditions in the field, especially in Kotesan Village, Prambanan District, many people still work in the agricultural sector and most of them have livestock such as goats and cows. Several incidents and deaths of goats and cows are also often found due to a lack of education about livestock care. There is a need for supplements and the fulfillment of livestock needs that are considered easy and basic. For this reason, the UNS 106 KKN team in Kotesan Village initiated the use of alternative feed as a supplement to the main feed in the form of silage and mineral blocks. Silage is used as a supplement and mineral blocks are used as additional nutrients to supplement the minerals needed by goats and cows. Until the training on making feed was held to educate farmers in Kotesan Village to prevent deaths due to paralysis and lack of livestock nutrition. With participants from the Joint Farmer Group in Kotesan Village, the UNS 106 Community Service Program team conducted training on making alternative livestock feed, namely silage and mineral blocks.

Abstract

Ketahanan pangan merupakan aspek penting dalam meningkatkan kesejahteraan masyarakat sekaligus mendukung upaya pengentasan kemiskinan dan pencegahan stunting. Desa Kotesan, Kecamatan Prambanan, Kabupaten Klaten memiliki potensi besar dalam pengembangan ketahanan pangan berbasis sumber daya lokal melalui sektor pertanian dan perikanan. Namun, potensi tersebut belum dimanfaatkan secara optimal akibat keterbatasan inovasi, keterampilan pengolahan serta rendahnya pengetahuan masyarakat mengenai diversifikasi pangan. Untuk menjawab permasalahan tersebut, mahasiswa Universitas Sebelas Maret melaksanakan program Kuliah Kerja Nyata (KKN) pada Juli–Agustus 2025 dengan tema “Ketahanan Pangan Mandiri dan Pengentasan Kemiskinan”. Program ini berfokus pada edukasi diversifikasi pangan dan workshop pengolahan pangan alternatif berbasis bahan lokal, seperti nugget lele dan pudding singkong. Kegiatan ini bertujuan meningkatkan pemahaman dan keterampilan masyarakat, khususnya ibu rumah tangga dan anggota Kelompok Wanita Tani (KWT), dalam memanfaatkan sumber daya lokal menjadi produk pangan yang lebih beragam, bergizi, serta bernilai ekonomis. Kegiatan KKN di Desa Kotesan tidak hanya berkontribusi pada peningkatan kapasitas masyarakat sebagai upaya memperkuat ketahanan pangan dan mengentaskan kemiskinan, tetapi juga sejalan dengan agenda pembangunan global untuk mewujudkan kesejahteraan masyarakat yang inklusif dan berkelanjutan.
