Analisis Struktur Box Girder Jembatan Fly Over Rawabuaya Sisi Barat Terhadap Gempa
The Rawabuaya flyover bridge is the solution that is offered by the local government to overcome the traffic jam that often happens in the Rawabuaya area. It has an extremely vital function to disentangle the traffic congestion; therefore the structure must be strong in holding the on-going load, specifically the seismic load. The seismic load is dangerous to a structure because it has period that causes the structure to repeatedly shaken. If the movements happened continually, the structure will collapse ― depending on how much earthquake load that is being loaded on the structure. Therefore, it is essential to conduct an structure analytical on the earthquake resistance level of Rawabuaya flyover bridge based on the "Standar Perencanaan Ketahanan Gempa Untuk Struktur Bangunan Gedung dan Non-Gedung" RSNI 03-1726-2010 and "Peta Zonasi Gempa Indonesia 2010" to know further about the on-going deformation. This research is done thoroughly by recognizing the maximum forces in the combination of ultimate loads based on the most recent rules of encumbering, including the rules regarding the seismic load. The maximum forces in the combination of ultimate loads will then compared with the forces' nominal values, especially those that related to the seismic load. From the research, it can be concluded that the values of maximum forces in the combination of ultimate loads have the combined seismic load that works on the upper structure of box girder as well as on the structure beneath the pier of Rawabuaya flyover bridge with a maximum momentum values of 800300,80 KNm that applies to Pier P6B with the combination of the singular ultimate load, the additional dead load, the prestress load, and the “T” truck load. Impairment to the structure is bound to happen if the combination of ultimate load is forced to work continuously on the Rawabuaya flyover bridge. Meanwhile, the result of the compared maximum forces in the combination of ultimate load with the values of nominal forces indicates that the Rawabuaya flyover bridge has a large amount of seismic load with 10% difference. It means this structure can resist 90% of ultimate seismic load, which requires the usage of reinforcements on the upper structure of box girder as well as the on the structure beneath the pier to increase the concrete stress power and the tendon on the upper structure of box girder to increase the tensile of the concrete

cepat sesuai prinsip-prinsip pemuatan, maka dalam penulisan skripsi ini menguraikan
tentang bagaimana, “Optimalisasi Penanganan Muatan Curah Batubara pada Kapal
MV. DK 01 saat Bongkar Muat”, mengapa terjadinya keterlambatan saat melakukan
bongkar muat dan mengapa muatan berkurang setelah selesai bongkar muatan
batubara di MV. DK 01.
Landasan teori yang menjelaskan tentang penanganan dan pengaturan yang
mengacu pada prinsip-prinsip pemuatan, muatan curah yang dalam pemuatanya harus
membutuhkan ruang palka yang didesain khusus untuk menghilangkan adanya
broken stowage , batu bara yang mempunyai karakter khusus dalam pemuatanya
dengan memperhatikan bahaya muatan tersebut, dan kegiatan bongkar muat yang
dilakukan serta alat-alat yang digunakan dalam proses bongkar muat
Metode yang digunakan oleh penulis adalah metode kualitatif, sedangkan
metode pengumpulan data yang digunakan adalah metode wawancara, observasi, dan
kepustakaan yang berhubungan dengan penanganan muatan terutama pada saat
bongkar muat.
Dari hasil penelitian tersebut kita ketahui bagaimana penanganan dan
pengaturan muatan curah batu bara berupa perencanaan, pembagian dinas jaga,
pelaksananan pemuatan dan pengawasan yang dilakukan serta kendala-kendala
adanya wire putus, wire loncat dan pengaturan buruh yang tidak sesuai prosedur.
Maka untuk memecahkan hal tersebut dibutuhkan adanya kerja sama yang baik dalam
bongkar muat ditunjang dengan pengawasan yang optimal serta perawatan alat
bongkar muat yang rutin, adanya pengadaan suku cadang yang dapat memperlancar
bongkar muat,
Berdasarkan dari hasil penelitian dapat disimpulkan bahwa penanganan dan
pengaturan muatan curah batu bara belum optimal dengan adanya kendala-kendala
tersebut yang tidak hanya dilakukan oleh operator crane tapi juga kurangnya
perawatan terhadap alat tersebut,. Dari simpulan diatas sebaiknya penanganan dan
pengaturan muatan batubara perlu memperhatikan prinsip-prinsip pemuatan, dengan
merawat alat bongkar muat dan pengawasan yang baik dan benar.

To achieve the goal of handling, managing and managing effectively,
efficiently and quickly according to the principles of loading, in writing this essay
describes how, "optimization of handling bulk coal loads on MV. DK 01 when
loading and unloading, why is there a delay when loading and unloading and why the
load is reduced after finishing loading coal in the MV. DK01.
The theoretical foundation that describes handling and regulation that refers to
the principles of loading, bulk load in loading must require a hatch space specifically
designed to eliminate broken stowage, coal which has a special character in its
loading by taking into account the cargo hazard, and activities loading and unloading
carried out and tools used in the loading and unloading process
The method used by the author is a qualitative method, while the data
collection method used is the method of interviewing, observation, and literature
related to cargo handling, especially when loading andunloading.
From the results of these studies we know how to handle and regulate coal bulk in the
form of planning, division of guarding, implementation of loading and supervision
carried out and constraints of wire breaks, jump wire and labor arrangements that are
not according to the procedure. So to solve this, good cooperation in loading and
unloading is supported by optimal supervision and routine maintenance of loading
and unloading equipment, the procurement of spare parts that can facilitate loading
and unloading,
Based on the results of the study it can be concluded that the handling and
regulation of coal bulk load has not been optimal with the existence of these
constraints which are not only carried out by crane operators but also the lack of
maintenance of these tools. From the above conclusions, it is better to handle and
regulate coal load, need to pay attention to the principles of loading, by maintaining
loading and unloading equipment and good and correct supervision

EKONOMI NARKOTIKA DAN RESISTENSI KOLEKTIF TERHADAP APARAT PENEGAK HUKUM: SUATU KAJIAN MENGENAI DINAMIKA DALAM RELASI KEKUASAAN ANTARA NEGARA DAN MASYARAKAT DI PERUMAHAN PERMATA JAKARTA BARAT
Perumahan Permata, a residential area located in West Jakarta commonly known as
Kampung Ambon, is an area plagued with high crime rate. The migrant community residing
in this area are originally members of the lower class stratum who find employment in
various kinds of street crime activities. In the pas few years, Perumahan Permata raises
growing public concerns over the existence of an illicit economy fuelled by illegal drugs
trafficking. The issue has not yet been utterly solved up until today since it involves a
network of community based organized crime at the grass root level whuch never hesitates
to openly resist law enforcement efforts. This phenomenon signifies a shift in the existing
state-society power relations.
By conducting a field research utilizing in-depth interviews and participatory
observation author attempts to explore the socio-economic factors behind this phenomenon,
in order to explain how the existing criminal network operates, as well as to explain how
collective resistance towards autjority might occur. Research findings show existing
connection between the development of narcotics economy and collective resistance
towards state authority in Perumahan Permata. Organized drufs trafficking increases the
capabilities of the resoective community to mobilize available power resources and
eventually strengthens its position towards the state. On the other hand, ineffective
behaviour of certain law enforcement officials who are secretly involved in criminal networks
makes it difficult for the state apparatus to gain legitimacy for taking repressive measures to
impose control over the illegal drugs trafficking acrivities in the area.

Dampak Dana Desa terhadap Ketimpangan Desa-Kota di Indonesia
This study aims to analyze whether the Village Fund (VF), which has been implemented for almost a decade since first implemented in 2015, has been able to reduce rural-urban inequality in Indonesia. Apart from being one of the national development priority agendas, reducing inequality is also one of the Sustainable Development Goals (SDGs) agendas. The research employs secondary data and consists of two main stages of analysis. First, a paired sample t-test was used to test the level of rural-urban inequality in Indonesia before (Pre) and after (Post) Village Fund. Second, the author analyzed the impact of the Village Fund on rural-urban inequality through a linear regression test. The results show that there is a decrease in rural-urban inequality by 0.0335 - 0.0462 after testing the Pre-VF and Post-VF. Meanwhile, using provincial-level panel data from 2016 to 2023, it was found that the decline of rural-urban inequality in Indonesia was affected by the Village Fund policy. It means that the Village Fund as one of the financial incentive policies for village development has an impact on rural-urban inequality reduction in Indonesia, although the impact is still extremely limited
