Model Baru Pelayanan Administrasi Pemerintahan Daerah dalam Era New Normal di Indonesia
This study departs from a new habit adaptation movement that changes people's social interactions as a rational choice amid the threat of the Covid-19 outbreak. The purpose of this article is to empirically test that the current model of local government administration services in the island sub-district is very inefficient and less productive so that it has an impact on meeting the basic needs of the community comfortably and equitably. Furthermore, the study offers a new model for Duo-TM, namely Face and Machine Meeting. This article demonstrates the need for empirical studies in the development of local government administrative service models to trace the difficulties and geographical risks caused by the Covid-19 outbreak. This is especially relevant if the author refers to the reasons for massive changes in various social dimensions and forces the adaptation of new habits. On the other hand, the era of the industrial revolution 4.0 places the power of technology and information as a means of innovating services that are convenient, fast, cheap, and of high qualit
Single electron transfer reactions and the synthesis of Chiral BODIPYs
PhD ThesisThis thesis is divided into two parts. Part one covers single electron transfer reactions
of electron deficient carbonyls and Grignard reagents whilst part two discusses our progress
towards the synthesis of axially chiral BODIPYs.
Part 1:
Reaction of 2,2,2-trichloro-1-arylethanones with PhMgBr resulted in a reduction to
give 2,2-dichloro-1-arylethanones. We have shown through by-product analysis and EPR
measurement that this reaction proceeds through a Single Electron Transfer (SET)
mechanism with PhMgBr acting as the electron donor. Addition of electrophiles to the
intermediate magnesium enolates, formed in the reaction, gave aldol, Claisen and
aldol/Tishchenko products.
Scheme 1 Reaction of PhMgBr with 2,2,2-trichloro-1-arylethanones followed by addition of
an electrophile
Scheme 2 General route for the synthesis of axially chiral BODIPYs
Resolution of a racemic axially chiral BODIPY was performed by preparative chiral
HPLC.
Scheme 3 Resolution of racemic-BODIPYs using HPLC
Electronic Circular Dichroism (ECD) spectroscopy and measurements showed
that the separated BODIPYs were enantiomeric. Comparison of measured and
computational ECD spectra allowed assignment of the absolute stereochemistry.
Part 2:
A number of BODIPYs have been synthesised which demonstrated axial chirality,
based on the restricted rotation of ortho-aryl meso substituentsIndonesian Ministry of National Educatio

PENERAPAN MESIN PENGASAP BAGI USAHA RUMAH TANGGA SE’I IKAN DI SEKITAR PANTAI KELURAHAN OEBA KOTA KUPANG
ASBTRAKIkan merupakan salah satu spesies yang banyak diminati oleh konsumen termasuk di Kota Kupang. Salah satu perolehan ikan di Kota Kupang di dapat dengan cara tangkapan dari laut yang jumlahnya cukup melimpah. Ikan-ikan hasil tangkapan nelayan selain langsung dijual untuk dikomsumsi ada pula yang dikeringkan secara alami dengan proses penggaraman dan bantuan sinar matahari. Setelah kering maka ikan tersebut dapat disimpan dan dijual segera. Kondisi tersebut menimbulkan permasalahan yaitu pengeringan ikan sangat tergantung dengan kondisi alam dan kadang cepat busuk karena kurangnya proses pengeringan sehingga menyebabkan nilai jual, cita rasa ikan yang dijual oleh nelayan ini menjadi jatuh. Selain itu ada juga yang mengolah hasil tangkapan dengan metode pengasapan. Untuk menghasilkan ikan asap bermutu, perlu pengetahuan tentang teori kesegaran ikan yang meliputi proses kemunduran mutu ikan, penanganannya untuk mempertahankan kesegaran ikan, penilaian kesegaran ikan baik secara subjektif (organoleptik) maupun secara objektif (laboratory). Selanjutnya, teknik pengolahan mulai dari pemilihan bahan baku, bahan asap, bahan pembantu, waktu dan suhu pengasapan, pengemasan, penyimpanan yang baik dan sesuai dengan SNI ikan asap,Dari pantauan dan hasil wawancara dengan salah satu usaha pengasapan ikan di kelurahan Oeba diperoleh data bahwa mereka sudah memulai usaha sejak tahun 2012 dengan kebutuhan ikan bahan baku sekitar 40 kg/hari namun peralatan yang digunakan masih sangat tradisionil. Program pengabdian pada masyarakat ini mencoba memberikan aplikasi praktis terapan di bidang perikanan dengan cara, pembekalan soft skill kepada beberapa masyarakat yang tergabung dalam sebuah usaha industri rumah tangga untuk dapat menerapkan teknik pengasapan ikan. Sementara itu mitra se’i ikan, berperan dalam penyediaan lahan untuk bagi pemanfaatan mesin pengasap. Hasil kegiatan menunjukkan bahwa mesin pengasap telah berfungsi dengan baik dan dapat dioperasikan oleh mitra tanpa hambatan yang berarti. Kata Kunci: se’i ikan; mesin pengasap; industri rumah tangga. ASBTRACTFish is a species in excellent consumer demand, including in Kupang City. One of the fish harvests in Kupang City is caught by catching them from the sea, which is relatively abundant. Apart from being directly sold for consumption, the fish caught by fishermen are also dried naturally with the salting process and the help of sunlight. Once dry, the fish can be stored and sold immediately. This condition raises problems, namely, the drying of fish is very dependent on natural conditions, and sometimes it spoils quickly due to a lack of drying process, causing the selling value and taste of the fish sold by these fishermen to fall. Apart from that, some process their catch using the smoking method. To produce quality smoked fish, knowledge of fish freshness theory is needed. It includes decreasing fish quality, handling it to maintain freshness, and assessing fish freshness subjectively (organoleptic) and objectively (laboratory). Furthermore, processing techniques start from selecting raw materials, smoked ingredients, supporting materials, smoking time and temperature, packaging, good storage, and following SNI smoked fish. They started their business in 2012 with a raw material fish requirement of around 40 kg/day, but the equipment used is still very traditional. This community service program tries to provide practical applications in fisheries by providing soft skills to several members of the home industry to apply fish-smoking techniques. Meanwhile, the fish se'i partners play a role in providing land for smoking machines. The activity results show that the smoking machine is functioning well and can be operated by partners without significant obstacles. Keywords: fish se'i; smoking machine; home industr
