PENGOPTIMALAN PRODUKSI DANDANG DESA PASAREAN ADIWERNA TEGAL MELALUI MANAJEMEN INVENTORY
Get PDFSalah satu usaha kerajinan logam yang berada di Desa Pasarean Kecamatan Adiwerna Kabuaten Tegal, yaitu UD Berkah Lestari adalah usaha yang bergerak di bidang kerajinan olahan logam, yakni Dandang. Permintaan akan produk Dandang di pasaran sangat besar. Produksi Dandang yang berlebihan akan menimbulkan penumpukan produk yang berakibat menurunkan kualitas barang sedangkan produksi Dandang yang sedikit akan tidak terpenuhinya permintaan pasar sehingga dapat kehilangan pelanggan.Permasalahan yang dihadapi oleh UD Berkah Lestari adalah bagaimana memanajemen inventory (persediaan) Dandang sehingga terjadi keseimbangan antara produksi dengan permintaan akan Dandang. Permintaan produk tetap terpenuhi dengan biaya yang dikelurkan seminimal mungkin sehingga dapat meningkatkan keuntungan.Kegiatan ini bertujuan untuk memberikan masukan akan manajemen inventory suatu usaha dengan biaya operasional yang dikeluarkan seminimal mungkin dan keuntungan yang didapatkan semaksimal mungkin melalui seberapa besar produk optimal yang harus diproduksi.Metode yang digunakan untuk mencapai tujuan adalah mengelompokan masalah dalam aspek bidang yang kemudian dipilih berdasarkan prioritas permasalahan serta IPTEKS yang diterapkan untuk menyelesaikan permasalahan prioritas. Manjemen inventory diterapkan pada persediaan akan produk dandan

No full textBusiness Model Development of Oil Palm Empty Fruit Bunch and Trunk Carbon Nanofibers – Based Water Purifier
No full textIndonesia have confronted the decrease in water quality due to mining, industry, agricultural practices, and waste disposal. Carbon nanofibers derived from oil palm empty fruit bunch (OPEFB) and oil palm trunk (OPT) have the economic potential to be commercialized as water purifier. This paper aims to analyze the potential economic value by means of a business model from OPEFB and OPT carbon nanofibers. The methods used in this paper were the qualitative method and the business model development. The result showed that the carbon nanofibers based–water purifier has high economic value. The economic value of this innovation is predicted to increase from 6.6 billion in 2015 in the market. Furthermore, the suitable business model for water purifier from OPEFB and OPT carbon nanofibers was the fabless business model (FLBM). That model is more focused on the core competencies (research, design, development) and marketing of the nanotechnology products. This FLBM was suitable for the new startup business with innovative technology to enter the market by collaborating with key partners (manufacture, government, academic, research center, and community)

No full textIn this research, the presence of students' attendance at the Taruna Bulu Vocational School has been observed where the system used is still manual so it requires a computerized system so that archiving is efficient and the homeroom teacher and student guardian can control student attendance.In conducting research, the author uses two sources of data, namely primary data which includes all data obtained by the author directly from sources obtained from the Head of Vocational School Hair Training and secondary data which includes all information obtained from other data that can be used as a support and related to the research theme. These data sources are documents concerning the student attendance information system procedures. In designing the system, it is made based on the needs of SMK Taruna Bulu which is then implemented using the PHP My SQL programming language and integrated Telegram Bot so that it can later be implemented on Taruna Bulu Vocational School
Valorization of Oil Palm Trunk Biomass for Lignocellulose/Carbon Nanoparticles and Its Nanomaterials Characterization Potential for Water Purification
No full textThis study has two broad objectives, which include: 1) valorization of oil palm trunk (OPT) biomass for non-activated carbon nanoparticles (NAc-CNPs) and lignocellulose nanofibers (LCNFs) and 2) characterization of these nanomaterials for heavy metal removal efficiency. These nanomaterials were also tested for their heavy metal adsorption efficiency. From this study, it was established that these nanomaterials have diameters size lesser than 100 nm. NAc-CNPs have a stacked particle structure, whereas LCNFs form web-like features with entangled individual LCNF; thus, they form more stable aggregates in dilute water than NAc-CNPs. In the aqueous state, NAc-CNPs comparatively had more aggregates with the appearance of bimodality and multimodality in particle size distribution. LCNFs have a higher crystallinity index due to the presence of deposited crystalline cellulose and silica crystallites. There was no pronounced chemical change in functional groups in both NAc-CNPs and LCNFs. These nanomaterials demonstrate excellent heavy metals removal efficiency and are favorable to adsorb Cu, Pb, Fe, and Zn ions, especially in contaminated water, wastewater, and peatland

No full textMorphological, Chemical, and Thermal Characteristics of Nanofibrillated Cellulose Isolated Using Chemo-mechanical Methods
No full textThe objective of this research was to analyze the morphology, crystallinity, elemental components, and functional group changes, as well as thermal stability of nanofibrillated cellulose (NFC). Nanofibrillated cellulose has an irregular and aggregated shape with a diameter of about 100 nm. NFC self-aggregations were observed due to hydrogen bonding and Van-der Waals forces. The cellulose crystallinity index, atomic size, and polymorph of the NFC sample were found to be 63.57%, 2.2 nm, and cellulose I, respectively. The NFC sample was composed of various elemental components, such as C, O, N, Na, Al, Si, and K. IR analysis showed only small amounts of hemicellulose and lignin deposits, whereas cellulose functional groups appeared in several wavenumbers. Aromatic and oxygenated compounds, such as
carboxylic acids, phenols, ketones, and aldehydes, were deposited as extractive on NFC; these compounds were associated with cellulose, hemicellulose, and lignin. The NFC thermal degradation process consisted of four steps: water evaporation (50-90 ºC); hemicellulose degradation and glycosidic linkage cleavage (250-325 ºC); amorphous cellulose and lignin degradation (325-429.29 ºC); and cellulose crystalline degradation (above 429.29 ºC)
