KEWENANGAN PEMERINTAH DAERAH DALAM PENGELOLAAN KEHUTANAN PASCA UNDANG-UNDANG CIPTA KERJA [The Authority of Local Governments in the Context of Forestry Management after the Law on Job Creation]
No full textThe Indonesian government initiated a law called Job Creation which aims to facilitate the flow of licensing bureaucracy to increase investment in Indonesia. However, there are problems that have come to the attention of the author regarding the regulation of forestry matters in this regulation, namely the centralization of authority to issue permits in the central government, the role of local governments in the formation and assessment of environmental impact analysis (AMDAL) and Environmental Management Efforts-Environmental Monitoring Efforts (UKL-UPL), and regarding the features of the National Strategic Project (PSN). These problems are the main discussion of the authors in this study. By using normative juridical research through a statutory approach as well as descriptive analytical concepts, the authors conclude that forestry regulations in these laws tend to restore the dignity of centralization of authority in the context of forest management authority, particularly with regard to forest use. This is not in line with the constitutional design regulated in the constitution regarding the division of authority for forest use between the central and regional governments which must be carried out based on the spirit of autonomy as wide as possible in a fair and harmonious manner.Bahasa Indonesia Abstrak: Pemerintah Indonesia menginisiasi sebuah Undang-Undang dengan nama Cipta Kerja yang bertujuan untuk mempermudah alur birokrasi perizinan untuk meningkatkan investasi di Indonesia. Namun, terdapat permasalahan yang menjadi perhatian penulis terkait pengaturan soal kehutanan dalam regulasi ini, yaitu pemusatan kewenangan pemberian izin di pemerintah pusat, peran pemerintah daerah dalam pembentukan dan penilaian analisis mengenai dampak lingkungan (AMDAL) dan Upaya Pengelolaan Lingkungan Hidup-Upaya Pemantauan Lingkungan Hidup (UKL-UPL), dan perihal keistimewaan Proyek Strategis Nasional (PSN). Permasalahan tersebut menjadi bahasan utama penulis pada penelitian ini. Dengan menggunakan penelitian yuridis normatif melalui pendekatan perundang-undangan serta konsep yang bersifat deskriptif analitis, penulis berkesimpulan bahwa pengaturan kehutanan dalam undang-undang tersebut cenderung mengembalikan marwah sentralisasi kewenangan dalam konteks kewenangan pengelolaan hutan, khususnya berkaitan dengan pemanfaatan hutan. Hal ini tidak selaras dengan desain konstitusional yang diatur dalam konstitusi mengenai pembagian kewenangan pemanfaatan hutan antara pemerintah pusat dan daerah yang harus diselenggarakan berdasarkan semangat otonomi seluas-luasnya yang adil dan selaras
SISTEM PAKAR DIAGNOSA PENYAKIT IKAN BERBASIS WEB MENGGUNAKAN METODE CERTAINTY FACTOR
Full text linkIn Jepara Regency, there are many fish sellers and breeders/cultivators. In the process of captive fish, usually fish cultivators will experience several problems, one of which is the emergence of disease in fish cultivated by fish cultivators. Prevention is a very effective step to minimize the risk of disease in farmed fish. If the fish are already diseased, the costs incurred for fish cultivation will increase due to the additional cost of fish treatment. Fish breeders need to know about fish diseases and how to treat them if the fish they farm are infected with diseases or pests. One of the efforts that can be done by fish breeders is by visiting fish disease experts (experts) which cannot be done continuously because it requires a lot of time, effort and money. From these problems, the author will create a website-based expert system for diagnosing fish diseases using the Certainty Factor method. With this application, it is hoped that it can assist fish breeders in dealing with diseases in protected fish, without having to visit an expert. In the author's research, testing was carried out based on 10 diagnostic samples, and calculated using k-fold cross validation, resulting in a system accuracy of 90%. Where the expert system that has been made by the author is considered feasible.Di Kabupaten_Jepara ini, terdapat banyak penjual dan peternak/pembudidaya ikan.

Temperature dependent scintillation properties and mechanisms of (PEA)<sub>2</sub>PbBr<sub>4</sub> single crystals
No full textIn this work the scintillation properties of PEA2PbBr4 are studied as function of temperature, accessing the potential use of these materials for low temperature applications. The scintillation properties and mechanism have been studied using a combination of temperature dependent photoluminescence emission and excitation, X-ray excited emission and decay measurements. At room temperature the X-ray excited emission is dominated by the 442 nm emission with a lifetime of 35.2 ns. Under UV-Vis photon excitation an additional emission peak is observed at 412 nm. At 10 K, both X-ray and UV-Vis photon excited emission spectra show a narrow emission peak at 412 nm and a broad emission band centred around 525 nm with a lifetime of 1.53 ns (24%) and 154 ns (76%) respectively. The exact nature of the observed emission peaks is not known. For this reason two potential mechanisms explaining the difference between UV-Vis photon and X-ray excitation and their temperature dependent emissions are explored. The total spectral intensity decreases to 72% of the intensity at room temperature at 10 K. It is suggested that the observed negative thermal quenching behaviour results from a combination of more self absorption and a higher degree of self trapped exciton formation under X-ray excitation. Based on the observed fast decay component at 10 K and light yield of 9400 photons per MeV at room temperature, showing only a 28% decrease at 10 K, could make this material potentially interesting for low temperature and fast timing applications.RST/Luminescence Material
Practical Method for Mix Design of Cement-based Grout
No full textAbstractCement-based grout is made of mixed water and cement, which is sometimes also added with sand and admixtures. It is commonly used for soil improvement, for repairing the damages on concrete and masonry, or for the construction of preplaced- aggregate concrete. Currently there are hardly any available practical methods which can be used to carry out the grout mix design. The practical method to carry out cement-based grout mix designs suggested in this paper is based on some graphics and or empirical equations, which are derived from regression analyses of laboratory test results data to simplify the mix design process

Diplomatic Bluff against Indonesia's G20 Presidency amid the Ukraine - Russia Conflict: A View from Political Psychology
Full text linkPolitical psychology has a pivotal role in the discipline of international relations, particularly in handling the conflict between Russia and Ukraine. The conflict severely affects all global aspects, from the economic to security, including Indonesia's G20 Presidency. This study aims to analyze how political psychology contributes to reducing or becoming the key to the performance of the Indonesian G20 Presidency in conjunction with the Russia-Ukraine conflict and diplomatic bluff by some countries. With descriptive qualitative research methods, and data collection techniques with literature studies from books, journals, and webpage news, data were analyzed, and conclusions were drawn. The Russia-Ukraine conflict not only threatens international peace and security order but also challenges Indonesia's G20 presidency as Russian Vladimir Putin gets invited to attend the summit. This article used the Tree Model, offering three mechanisms by prioritizing psychopolitics and psychoanalysis, which can be a reference for conflict resolution. This tree model is expected to be applied in response to the Russia-Ukraine conflict, bridge differences between all G20 members, and help Indonesia be well-prepared and successful for the summit
Evaluasi Kapasitas Dan Tingkat Pelayanan Gerbang Tol Kuningan 2 Pada Ruas Jalan Tol Cawang-Tomang, Jakarta Selatan
Full text linkJalan Tol adalah jalan umum yang merupakan bagian dari sistem jaringan jalan dan sebagai jalan nasional yang pengendaranya diwajibkan untuk membayar tol. Salah satu jalan tol yang sangat berpengaruh terhadap pertumbuhan dan kestabilan ekonomi adalah jalan Tol Cawang-Tomang. Fungsi jalan tol harus memberikan fasilitas berupa kelancaran arus kendaraan tanpa hadirnya hambatan, maka untuk mewujudkan arus bebas hambatan yang sempurna jalan tol harus memiliki tingkat pelayanan minimal yang mencakup kondisi jalan tol, kecepatan tempuh rata-rata, aksesibilitas, mobilitas dan keselamatan. Faktor yang mempengaruhi terjadinya kemacetan di jalan tol salah satunya adalah kondisi dan kapasitas jalan tol itu sendiri dan juga proses antrian di gerbang tol. Pada Gerbang Tol Kuningan 2 kenyataannya sering sekali terjadi antrian yang panjang menyebabkan kemacetan pada kedua jalan yang mengakses gerbang tol tersebut, yaitu Jl. Kapten Tendean dan Jl. Gatot Subroto.
Untuk menciptakan akses tol yang bebas hambatan, maka perlu diteliti dan dikaji tentang permasalahan – permasalahan yang ada, apakah sudah memenuhi standar yang diperlukan. Standar yang dimaksud adalah Standar Pelayanan Minimal (SPM). SPM adalah ukuran yang harus dicapai dalam pelaksanaan penyelenggaraan jalan tol. Kepala Badan Pengatur Jalan Tol (BPJT) Kementerian PUPR Danang Parkesit menyatakan, target pelaksanaan konstruksi MLFF dimulai pada tahun 2021. Sistem Multi Lane Free Flow (MLFF) ini akan meniadakan antrian pada gerbang tol maka dari itu perlu dikaji kapasitas dari tiap lajur pada gerbang tol dengan sistem MLFF ini untuk mendapatkan kapasitas dan tingkat pelayanan yang maksimal dari gerbang tol tersebut.
Dengan melihat adanya permasalahan seperti yang sudah dijelaskan diatas maka, penulis mengambil judul Tugas Akhir ini untuk mengevaluasi antrian yang terjadi pada gerbang tol. Metode antrian FIFO digunakan untuk menganalisis tingkat kedatangan, tingkat pelayanan dan panjang antrian yang terjadi pada gerbang tol dan metode analisis kapasitas jalan PKJI digunakan untuk mengetahui kapasitas gerbang tol MLFF.
Dari hasil analisis didapatkan kesimpulan bahwa gerbang tol Kuningan 2 memiliki jumlah antrian sebanyak 599 kendaraan dengan waktu pelayanan sebesar 12 detik dari tingkat kedatangan yang terjadi. Untuk tingkat kedatangan yang terjadi pada gerbang tol didapatkan sebesar 1198 kendaraan/jam dengan sebesar 628,5 kendaraan/jam pada Gate 1 dan sebesar 569,5 kendaraan/jam pada Gate 2. Dari tingkat kedatangan yang terjadi maka Gerbang tol Kuningan 2 belum memenuhi persyaratan kapasitas gerbang tol. Untuk tingkat pelayanan didapatkan waktu pelayanan rata-rata gerbang tol sebesar 4 detik/kendaraan yang sudah memenuhi persyaratan tingkat pelayanan gerbang tol. Untuk jumlah gardu didapatkan perlunya penambahan sebanyak 2 GTO secara tandem pada gerbang tol Kuningan 2. Untuk gerbang Multi Lane Free Flow pada gerbang tol Kuningan 2 didapatkan kapasitas sebesar 1033,1 skr/jam/lajur dengan volume kendaraan yang terjadi sebesar 671,506 skr/jam/lajur.

Toll roads are public roads that are part of the road network system and as a national road whose drivers are required to pay tolls. One of the toll roads that is very influential on economic growth and stability is the Cawang-Tomang Toll Road. The function of the toll road must provide facilities in the form of a smooth flow of vehicles without the presence of obstacles, so to realize a perfect barrier-free flow the toll road must have a minimum level of service which includes toll road conditions, average travel speed, accessibility, mobility and safety. One of the factors that influence the occurrence of congestion on toll roads is the condition and capacity of the toll road itself and also the queuing process at toll gates. The Kuningan 2 Toll Gate which is located in the Cawang-Tomang toll area or the Jakarta Inner Ring Road is very influential on economic stability for the area because many office centers and shops in the area depend on smooth operation. But in reality there are often long queues causing congestion on the two roads that access the toll gate, namely Jl. Kapten Tendean and Jl. Gatot Subroto.
To create an obstacle-free toll road access, it is necessary to research and study the existing problems, whether they meet the required standards. The standard in question is the Standar Pelayanan Minimal (SPM). Standar Pelayanan Minimal (SPM) is a measure that must be achieved in the implementation of toll road operations. The Head of the Toll Road Regulatory Agency (BPJT) of the PUPR Ministry, Danang Parkesit, stated that the target for the MLFF construction to start in 2021. Then the implementation will gradually begin in 2022 with a scheme of 50% of the total substations at toll gates will be used by MLFF, while 50% is used for users who make conventional non-cash payments. This Multi Lane Free Flow (MLFF) system will eliminate queues at toll gates, therefore it is necessary to study the capacity of each lane at toll gates with this MLFF system to obtain maximum capacity and service levels from these toll gates. By looking at the problems as described above, the author takes the title of this Final Project to evaluate the queues that occur at toll gates. The FIFO queuing method is used to analyze the arrival rate, service level and queue length that occurs at toll gates and the PKJI road capacity analysis method is used to determine the capacity of the MLFF toll gate.
From the results of the analysis that has been carried out, it can be concluded that the Kuningan 2 toll gate has a queue of 599 vehicles on a service time of 12 seconds from the arrival rate that occurs. The arrival rate that occurs at the toll gate is 1198 vehicles/hour with 628.5 vehicles/hour at Gate 1 and 569.5 vehicles/hour at Gate 2. From the arrival rate, the Kuningan 2 toll gate does not meet the toll gate capacity requirements. For the level of service, the average service time of the toll gate is 4 seconds/vehicle that has met the requirements of the toll gate service level. For the number of booths, it is necessary to add 1 automatic toll booth at the Kuningan 2 toll gate. For the Multi Lane Free Flow gate at the Kuningan 2 toll gate, a capacity of 1033.1 skr/hour/lane is obtained with the volume of vehicles occurring at 671.506 skr/hour/lane
