Sumber tegangan listrik merupakan salah satu kebutuhan primer modern di masa sekarang.Sumber tegangan listrik mutlak dibutuhkan untuk menjamin tetap bekerjanya peralatan tersebut.

Namun masalah yang sering dihadapi seringkali adalah sumber-sumber tegangan memiliki nilai yang jauh dibawah level tegangan kerja yang umumnya digunakan pada sistem jaringan listrik perumahan. Untuk mengatasai permasalah sumber tegangan DC tersebut, salah satu cara yang dapat diambil adalah dengan mengimplementasikan sebuah rangkaian pengubah nilai tegangan DC atau DC-DC Converter.

Pada penelitian ini penulis menawarkan rangkaian DC-DC Converter dari tipe terisolasi, yaitu Push-Pull Converter. Pemilihan Push-Pull Converter dilakukan atas beberapa alasan antara lain keandalan, kualitas daya yang dihasilkan, kemudahan untuk diaplikasikan serta yang paling penting adalah ketahanan dari gangguan yang mungkin terjadi.

Sistem dikendalikan dengan menggunakan Pengendali PI dan IP serta diuji kualitasnya dengan menggunakan Diagram Bode.Hasil dari simulasi serta analisa kestabilan menunjukkan bahwa Rangkaian Push-Pull adalah rangkaian yang tahan terhadap gangguan.


Power supply is one of the modern primary needs in the present. Power supply is absolutely necessary to ensure the continuity cooperation of the equipment. However, a problem that often encountered is voltage sources values are far below the working voltage levels that are generally used in residential electrical grid system. To handling the problems of the DC voltage source, one way that can be taken is to implement a DC voltage converter circuit or DC-DC Converter.

In this research, a series of isolated type DC-DC Converters, namely Push-Pull Converter, is being promoted. The Selection of Push-Pull Converter based on reliability and quality of generated power among others, ease of applicability and the most important is the robustness of the interference that may occur.

The system is controlled using a PI controller and the IP also stability tested using Bode plots. The results of simulation and analysis shows that the stability of the Push-Pull circuit is a circuit that is resistant to interference.

"Dalam konteks hubungan antara SMS dan penyedia konten, ada dua cara yang digunakan untuk menyampaikan pesan, yaitu Pull dan Push. Dalam skenario Pull pengguna akan mengirim keycode tertentu kemudian sistem milik penyedia konten akan merespon dengan mengirimkan konten yang diminta. Sedangkan pada skenario Push penyedia konten akan melakukan broadcast konten ke kumpulan nomor yang terdaftar.
Kebanyakan penyedia konten akan mem-broadcast konten mereka begitu saja tanpa memiliki mekanisme untuk mengontrol proses, status pengiriman, serta tingkat kesuksesan pengiriman itu sendiri. Berkaitan dengan hal tersebut maka skripsi ini dibuat yaitu untuk merancang bangun suatu sistem yang mempunyai kemampuan untuk mengendalikan proses push/broadcast, sehingga saat kondisi jaringan di sisi operator sedang sibuk broadcast dapat dihentikan sementara untuk dapat dilanjutkan kemudian saat kondisi memungkinkan.
Dari hasil skripsi ini tergambar bahwa tingkat keberhasilan proses broadcast (push) ditentukan oleh beberapa kondisi, diantaranya adalah cara broadcast serta waktu saat broadcast dilakukan. Dua hal ini adalah parameter yang bisa dimonitor dan dikendalikan. Dari hasil pengujian dan analisa didapat bahwa proses push tanpa delay (cara broadcast dilakukan, waktu idle antara dua proses pengiriman yang berurutan) yang dilakukan pada peak-hour (waktu saat broadcast dilakukan) hanya memiliki success-push-rate rata-rata sebesar 37%, sedangkan jika cara yang sama dilakukan diluar peak-hour maka success-push-rate akan meningkat menjadi rata-rata 96%. Jika cara broadcast diubah dengan menambahkan delay 1 detik saja, maka success-push-rate akan meningkat menjadi 100%, dan hasil ini tidak terpengaruh oleh waktu saat broadcast dilakukan, saat peak-hour atau diluar peak-hour.

In relationship between SMS and content provider, there is two ways that related to how a content delivered to end user, Pull and Push. Pull process is initiated by end-user as they send specific-and-predefined keycode to content provider system, the system will reply back with requested information. In Push scenario, system will initiate the process to broadcast a content to several registered number.
Most of content providers are directly broadcast their contents as it is without having a mechanism that could monitor the process itself. In that context this paper come up with the idea to design and implement the system with such capability. So during broadcast contents when network condition going unpredictably-high traffic the system can hold the push process temporarily and resume the process later, when the network traffic in more acceptable condition.
Result from this paper give some quantitive figure that shows that the level of succesfulness of broadcast/push process is tightly-related with several conditions, two of them are how the push process executed and when push process executed. These are two parameters that can be monitored and controlled. From some testing and data analysis it revealed that a push process without a delay (idle time between two consecutives send message, related to how push executed) during a peak-hour (related to when the push executed) suggested averagely 37% in success-push-rate, but when the same way of push is executed during a non peak-hour time then the success-push-rate positively increase to averagely 96%. If we change the way of push process is being executed by adding 1 second delay, the success-push-rate would stay at 100% regardless when the push is executed, during peak-hour or not."

"Kehadiran aroma telah menjadi bagian dari keseharian manusia. Namun, belum banyak manusia yang memaknai kehadiran aroma dalam ruang. Hal ini diakibatkan karena wujudnya yang tidak kasat mata dan sifatnya yang perseptif. Aroma dapat dihadirkan secara sengaja dan tidak disengaja dengan strategi separation, deodorisation, scenting dan masking. Aroma memiliki peran dalam menentukan perilaku manusia seperti pikiran dan gerakan. Pull-in, push-out, dan netral, adalah tiga gerakan dari respon manusia terhadap kehadiran aroma dalam ruang. Studi pada skripsi ini dilakukan sebagai upaya untuk mengetahui seberapa jauh indera penciuman berperan dalam mengalami ruang urban. Pengamatan yang dilakukan pada akhirnya menunjukkan bahwa adanya kaitan antara strategi kehadiran aroma, respon gerak dari strategi tersebut, yang kemudian akan dikaitkan dengan teori pembentukan wilayah secara acak.

The presence of aroma has becoming a part of human daily life. However, there are still many people who have not interpreted the presence of aroma in space. This is due to its invisible form and perceptive characteristic. Aroma can be presented intentionally and unintentionally with the separation, deodorisation, scenting and masking strategies. Aroma has a role in determining human behavior such as thoughts and movements. Pull-in, push-out, and neutral, are three movements of human response toward the presence of aroma in space. The study in this thesis was conducted in an effort to find out how far the sense of smell plays a role in experiencing urban space. The observations showed that there was a link between the strategy of the presence of aroma, the movement responses due to the strategy, which would then be linked to the theory of random territorial walk."

"Intensi berganti produk pada konsumen perlu menjadi pertimbangan produsen karena perilaku konsumen tersebut dapat memberikan dampak pada perusahaan. Pengukuran intensi berganti sudah banyak dilakukan dengan menerapkan Push-Pull-Mooring Model untuk melihat faktor yang mempengaruhi intensi berganti. Penelitian-penelitian yang sudah ada masih minim melibatkan pendekatan informasi sebagai faktor yang mempengaruhi intensi berganti. Oleh karena itu, penelitian ini berusaha mengintegrasikan Information Adoption Model (IAM) ke dalam Push-Pull-Mooring Model untuk melihat pengaruh informasi terhadap intensi berpindah. Penelitian ini menggunakan paradigma positivistik dengan menerapkan logika deduktif dan pendekatan kuantitatif untuk membuktikan dugaan yang sudah dirumuskan. Sampel pada penelitian ini diambil secara purposive dengan karakteristik merupakan anggota atau pembaca informasi di komunitas daring Female Daily Network. Data primer diambil dengan teknik online survey menggunakan Google Form yang dikirimkan kepada followers Instagram dan twitter dari akun FDN. Desain penelitian yang digunakan adalah cross-sectional study. Hasil penelitian menunjukkan bahwa kegunaan informasi yang dikategorikan sebagai pull factor tidak memiliki pengaruh signifikan terhadap intensi berganti. Sedangkan, penelitian ini menunjukkan bahwa E-WOM negatif yang dikategorikan push factor memiliki pengaruh signifikan terhadap intensi berganti. Penelitian ini juga menunjukkan bahwa adopsi informasi yang dikategorikan sebagai mooring factor tidak memiliki pengaruh signifikan terhadap intensi berganti. Secara keseluruhan, model dalam penelitian ini memiliki berkontribusi yang cukup rendah dalam memprediksi intensi beganti pada konsumen kosmetik dalam komunitas daring.

The switching intention on consumers is an important issue for any firm because it could give negative impact on business. The switching intention measurement has been carried out by applying the Push-Pull-Mooring Model to measure the factors that influence the switching intention. The prior studies of PPM Model have not measured the information approach as a factor that influencing switching intentions. Therefore, this study attempt to integrate the Information Adoption Model (IAM) into the Push-Pull-Mooring Model to assess the effect of information on switching intention. This study used a positivistic paradigm by applying deductive logic and quantitative approach to prove the formulated assumptions. The sample of this study was purposively taken by considering samples characteristic. Primary data was collected using an online survey technique with Google Forms that was sent to the followers account of Female Daily Network on Instagram and Twitter. The questionnaire was filled independently by respondents or self-administered. The research design of this research is a cross-sectional study. The results of this study indicated that information usefulness that categorized as push factor has not a significant effect towards switching intention on cosmetic products. Meanwhile, the result indicated that negative E-WOM categorized as push factor has a significant effect towards switching intention. Information adoption that categorized as mooring factor has not a significant effect towards switching intention. The overall model in this research has low contribution to predict switching intention on cosmetic consumers in online community."

"ABSTRACT
Investasi langsung asing merupakan kegiatan yang melibatkan kebijakan dua negara, yakni negara asal dan tujuan. Selama beberapa tahun terakhir, Singapura telah menjadi sumber investasi langsung asing terbesar bagi Indonesia. Hal ini unik mengingat kecilnya Singapura dan lebih besarnya peran negara tersebut sebagai tujuan penanaman modal, dan bukan negara asal. Di masa pemerintahan Joko Widodo, Jepang masih tetap hadir sebagai partner ekonomi terlama Indonesia dan Tiongkok nilai investasinya sedang meningkat tajam. Namun, Singapura tetap tak beranjak. Dilihat dari push factor, hal ini dapat terjadi karena Singapura perlu melakukan investasi untuk memenuhi akses terhadap sumber daya dan pasar untuk memenuhi kekurangan geografis dan demografis yang ada. Di sisi lain, pull factor Indonesia mendukung hal ini karena sumber daya yang dimiliki memang menjadi daya tarik utama bagi investasi yang datang. Selain itu, Indonesia juga memiliki iklim ekonomi dan politik yang baik. Kebijakan Indonesia terhadap investasi Singapura cenderung terpisah dari kepentingan politik, tidak seperti kebijakan Indonesia terhadap investasi Jepang dan Tiongkok. Di luar push and pull factor kedua negara, terdapat pula hal lain yang berpengaruh, yakni dinamika kawasan maupun dinamika investasi negara lain, terutama Jepang. Kombinasi push and pull factor serta faktor pendukung menjadikan Singapura masih belum terkalahkan sebagai negara asal investasi langsung asing terbesar bagi Indonesia.

ABSTRACT
FDI an activity involving two countries home and host countries. During the past few years, Singapore has been the biggest FDI home country for Indonesia. This is unique knowing how small Singapore is and its bigger role as host country in the global investment world. In Joko Widodo era, Japan stays to be Indonesias oldest economic partner and China has been increasing its investment in Indonesia rapidly. Still, Singapore thrives. Seen from the push factors, this is the result of Singapores need of investment to gain access to resources and market to make up for its geographic and demographic shortage. On the other hand, Indonesias pull factors supports this because the countries resources has been known to be the primary attraction for foreign investors. Its stable economic and political climate also become other pull factors. Indonesias policy towards Singapores FDI tends to be apart from political interests, while towards Japan and China, these interests are quite apparent. Apart from these push and pull factors, there lies other contributing facts, specially from the region and investing countries dynamics, especially Japan. These combinations of push and pull factors, added by supporting factors, are the reason behind Singapores thriving role as Indonesias biggest source of FDI. "
