ABSTRAK. Kesehatan menjadi aspek penting yang harus diperhatilkan dalam desain rumah. karena rumah yang sehat akan berdampak pada kenyamanan yang dirasakan oleh penghuni. Penelitian ini bertujuan untuk mengetahui perubahan tata ruang rumah tipe kecil ≤ 36 m2 dan pengaruh perubahan tersebut pada aspek kesehatan penghuninya. Kesehatan difokuskan pada sirkulasi udara dan cahaya (penghawaan dan pencahayaan) yang merupakan dua aspek penting pada kesehatan dalam rumah. Metode yang digunakan adalah metode deskriptif kualitatif dengan mengambil kasus secara purposif sampling. Hasil yang didapatkan dari penelitian ini adalah pada perubahan tata ruang rumah tipe kecil selalu ada ruang yang tidak mendapatkan pencahayaan secara maksimal. Arah perubahan pada rumah tipe kecil adalah ke arah samping, belakang dan depan sehingga sirkulasi udara dan cahaya yang awalnya dioptimalkan melalui halaman depan dan belakang menjadi terganggu. Upaya yang dilakukan adalah dengan membuat bukaan berupa jendela dan roster yang cukup lebar sehingga udara dan cahaya dapat masuk ke dalam ruangan. Namun untuk ruang yang tidak mendapatkan cahaya matahari secara langsung akan menjadi gelap dan lembab sehingga mempengaruhi kesehatan penghuninya.Kata kunci: tata ruang, rumah, kesehatanABSTRACT.

Along with the times, every human level and life will be upgraded automatically. Likewise, the company if it does not adjust to the times, it will be difficult to adjust. As with the production process, there will be differences from time to time. From time immemorial, doing work manually, and in the present era using technological tools. Lifting the car seat manually makes the operator complain of pain, due to the high production volume. To eliminate the complaints from these operators, a proposed tool design was made. The method used is Axiomatic House of Quality. In general, Axiomatic Design can help the product development process be more structured with a focus on design that fits the function of the product. The first step in this research is to collect input from customers. Then after getting input from the customer, it is converted into a customer attribute. Then, develop the concept by making several alternatives based on the combination table. Next, determine the design that will be used and carry out testing and coordinate with the user, namely the assembly operator. Finally, determine the specifications and final design of the tool for lifting a seat whose load exceeds the lifting standard. The results of this study are in the form of a design tool for lifting the seat which is expected to reduce complaints of pain to the operator. So that this design design makes the company a consideration for implementation.

The use of composite materials in Indonesia, as a nonmetal alternative material has begun to increase. Composite use has grown from water tanks from fiberglass materials, household appliances, children's toys, sports equipment, furniture/interior design to automotive components and aircraft. Many of the advantages of this composite material include hand, strong, anti-corrosion, finely tuned finish. Its mild nature has a direct impact on energy savings. The prospect of composite materials as a non-metal alternative material is rapidly growing and its use. Various types of reinforce used can be influenced by the prices available, so seek alternatives as a commonly used glass fiber substitute woven rowing. The substitute used is a sack of gourds of the same kind as woven rowing, from which the same type of fiber is tried to find its strength by undergoing a pull test. And as a result of the test the mateial can know its power.

Quality is a factor that determines the success of a product penetrate the market, in addition to other major factors such as price and service. Quality products will have great competitiveness and high quality level. Products produced from extracts of natural ingredients, one product is Black Tea extract. To maintain customer satisfaction, the company tries to emphasize the value of DPU that occurs. This study aims to analyze the defect reject from the production of Black Tea Extract for a year using SIPOC diagram (Supplier Input Process Output) and Pareto diagram. Result of research is total production during that period equal to 358 batch x 300 Kg = 107400 kg, total reject of 78 batch x 300 kg = 23400 kg, with total reject for Black tea extract 21,79%. Can be known in the process of Black Tea extract reject largest in reject brix out of spec for 93.67% and Reject Tannin out of spec 6.33%. So it can be concluded that the dominant reject of the production process for black tea extract products is reject brix out of spec.

Semakin meningkatnya pemahaman masyarakat terhadap industry yang menerapkan zero waste, mendorong semakin banyaknya kajian dan riset mengenai pemanfaatan bahan alam yang berasal dari hasil samping suatu industry, baik skala kecil maupun besar. Padi merupakan komoditi bahan pangan pokok bagi masyarakat Indonesia dan produksinya melimpah, sehingga hasil sampingnyapun cukup banyak, seperti sekam, jerami, dedak, bekatul. Dedak padi adalah salah satu hasil samping agroindustri pengolahan padi dan di dalamnya terkandung berbagai macam bahan yang bermanfaat seperti protein, mineral, serat, dan minyak, serta berbagai bioaktif seperti feluric acid, g-oryzanol. Adapun Tujuan penelitian ini adalah melakukan analisis pasar dan produk terhadap produk perawatan tubuh dengan menggunakan bioaditif bersumber dari hasil samping industry agro, selanjutnya menginterpretasikan dan pengolahan data serta menentukan spesifikasi produk yang diinginkan oleh masyarakat. Metodologi penelitian ini adalah 1). Melakukan pengumpulan data mengenai kebutuhan masyarakat terhadap produk hasil diversivikasi dedak padi untuk keperluan non pangan 2). Melakukan interpretasi dan pengolahan data; 3). Menentukan Spesifikasi Produk yang diinginkan konsumen. Hasil penelitian menunjukkan bahwa dari hasil penyebaran dan olahan kusioner untuk produk Tamanu Cleansing Oil dapat disimpulkan bahwa layak untuk diproduksi dan dipasarkan ke konsumen sebagai pembersih kulit muka, dengan perbaikan yang harus dilakukan yaitu tekstur dibuat menjadi lebih lembut sehingga nyaman digunakan. Sedangkan produk Body Lotion Pitoe layak untuk diproduksi dan dipasarkan ke konsumen dengan beberapa perbaikan seperti : Tekstur dari body lotion pitoe lebih dilembutkan dan tidak encer.

Mesin Air Blast Freezer (ABF) adalah salah satu alat pembeku makanan dalam dunia refrigerasi. Dalam perancangan Air Blast Freezer ini, tahapan yang paling menentukan adalah saat perhitungan beban kalor yang akan menjadi acuan bagi perancang dalam pemilihan kompresor. PT. XYZ dalam hal ini untuk memenuhi permintaan pelanggan untuk 2 unit ruangan ABF dengan kebutuhan membekukan adonan roti berkapasitas 250 kg/jam di tiap ruangan melakukan perhitungan beban kalor ABF dengan asumsi total beban kalor sebesar 41,5 kW dan menggunakan kompresor 62WBHE 900rpm sebagai penopangnya. Sehingga saat ini terdapat 2 kompresor tipe 62WBHE 900rpm yang berjalan, dan 2 unit kompresor yang sama direncanakan untuk projek 2 ABF selanjutnya. Kondisi aktual yang didapatkan dengan cara observasi dan analisa perhitungan serta pemilihan kompresor, beban kalor ternyata hanya 37,81 kW, dan cukup apabila hanya menggunakan kompresor 42WBHE 900rpm yang ukurannya lebih kecil dan kebutuhan dayanya juga lebih kecil.

Pada masa pandemi ini, guru tidak lagi berperan sebagai sumber utama pembelajaran. Sebaliknya, mereka sekarang berperan sebagai fasilitator yang dibutuhkan untuk menggunakan teknologi yang berkembang untuk mendukung pembelajaran jarak jauh. Untuk membantu mitra dalam hal ini, dengan guru-guru Raudhatul Athfal (RA) dan Madrasah Ibtidaiyah (MI) di Yayasan Baitul Ulum, diberikan pelatihan pembuatan blog. Blog juga digunakan sebagai sarana pembelajaran tambahan dan sebagai alat literasi digital guru. Platform ini berfungsi sebagai media pembelajaran berbasis blogger dan menerapkan pendekatan konstektual untuk hasil Pendidikan secara daring. Metode yang digunakan diantaranya (1) Konsep pemanfaatan weblog dalam penyebaran informasi di bidang Pendidikan, (2) Pengenalan blog yang akan digunakan blogspot, (3) Praktik cara menggunakan blog secara dasar (4) Praktik cara mengisi konten dalam blog, berupa: teks, gambar, maupun video dan (5) pengenalan media pembelajaran lainnya. Dengan menggunakan pendekatan pembelajaran ini, kami telah menemukan bahwa blog dapat digunakan untuk menyelesaikan masalah media pembelajaran yang berbeda di sekolah. Diharapkan ke depan, guru-guru dapat menggunakan blog sebagai alat pembelajaran untuk menarik perhatian dan minat siswa.
