Abstract

Jaringan pipa air bersih memiliki peran penting untuk memenuhi permintaan air bersih masyarakat setempat. Apabila debit dan kehilangan tinggi tekanan dalam jaringan pipa cukup besar, air tidak akan terdistribusi dengan baik. Oleh sebab itu, salah satu cara untuk menanganinya ialah dengan memperhatikan ukuran diameter pipa yang digunakan. Penelitian ini bertujuan untuk menentukan optimasi jaringan pipa distribusi air dengan mengoptimalkan diameter pipa. Penelitian ini menggunakan metode pemrograman linear dengan bantuan fitur Solver pada Microsoft Excel untuk menyelesaikan masalah optimasi dengan cara mengubah masalah menjadi bentuk persamaan matematika. Berdasarkan jaringan pipa distribusi air bersih di Kecamatan Pagak, Kabupaten Malang, terdapat 115 elemen pipa yang perlu dioptimasi. Hasil menunjukkan bahwa ada 13 pipa yang dapat dioptimasi, yakni pipa 3 dari diameter 3 inci menjadi 2,5 inci dengan persentase optimasi 25,445%, pipa 4 dari diameter 2 inci menjadi 1,5 inci dengan persentase optimasi 6,557%, pipa 5 dari diameter 2 inci menjadi 1,25 inci dengan persentase optimasi 23,578%, pipa 6 dan pipa 7 dari diameter 3 inci menjadi 2,5 inci dengan persentase optimasi 25,445%, pipa 11 dan pipa 16 dari diameter 3 inci menjadi 2 inci dengan persentase optimasi 42,1675%, pipa 18 dan pipa 22 dari diameter 3 inci menjadi 2,5 inci dengan persentase optimasi 25,445%, pipa 24, pipa 31, pipa 33, pipa 37, dan pipa 39 dari diameter 1,5 inci menjadi 1,25 inci dengan persentase optimasi 18,216%. Optimasi diameter pipa tersebut pun mampu meminimalisasi biaya dari Rp811.916.496,36 menjadi Rp763.589.044,08. Hasil penelitian membuktikan bahwa proses optimasi berjalan dengan baik karena penurunan ukuran diameter pada beberapa elemen pipa membuat anggaran biaya pada elemen-elemen pipa tertentu akan ikut menurun.

Abstract

Crime through language is now facilitated by the presence of the internet in the digital era, for example via WhatsApp, line, SMS, Facebook, Instagram, YouTube channels, and so on. Social media of all kinds helps facilitate language crimes. Due to the existence of different media in committing crimes, namely through electronic and non-electronic media, Indonesia imposes different legal rules between the two. Facts in the field, case handling with a forensic linguistic approach is relatively rarely done optimally because of the limited ability of investigators in the field of forensic linguistics, action research is carried out by intervening in forensic linguistic knowledge to Police investigators, both with case practicum, and the application of the ELAN application method (EUDICO Linguistic). Annotator) and PRAAT, as well as AntConc software version 3.5.9 and AntWordProfiler 1.5.1. Action research was carried out at four Polda, namely the East Nusa Tenggara Regional Police, the North Sulawesi Regional Police, the East Java Regional Police and the North Sumatra Regional Police.The obstacle faced by investigators in handling legal cases that stem from the linguistic aspect is that investigators at the police stations find it difficult to find expert witnesses because there are no expert witnesses who are considered capable of in the field of forensic linguistics, the lack of support for the infrastructure to uncover language-based crimes, Inadequate ability of investigators in understanding forensic linguistics and the use of software or it related to forensic linguistics, Inadequate research budgets, especially in island areas and the inability of investigators to identify utterances or discourses that are considered a crime or use linguistic analysis to uncover cases crime Keywords: capacity building, forensic linguistics, National Police investigators

Abstract

Health services are one of the basic services by the government in addition to education services and basic needs. Likewise for PNPP, especially through the Police FKTP. However, until now research on health services in Polri has been dominated by health services in hospitals. In fact, FKTP plays an important role as a gate keeper in the national health service system. As a result, little is known about the Police's FKTPs. This study aims to determine health services in the Police FKTP in terms of four aspects, namely the availability of health facilities, the types of health services and their quality, the PNPP's understanding of health insurance owned and its utilization, and the constraints in managing the Police FKTPs in the sample Polda ranks. Based on the use of mixed methods with a triangulation strategy, the data collection for this research was carried out by distributing questionnaires with a Google form, FGD, and observing the Police FKTP. The sample Polda consisted of 11 Polda, namely Polda Aceh, Riau, Yogyakarta Special Region, South Kalimantan, West Sulawesi, West Papua, Maluku, West Nusa Tenggara, East Kalimantan, Bangka Belitung Islands, and Gorontalo. The number of respondents who filled out the questionnaire was 23,643 police personnel. The FGD at Polda was conducted with the Head of BPJS Kesehatan Branch Office, Karo SDM, Head of HR, Kabiddokkes, Head of Hospital, Head of Polyclinic. The FGD at the Polres was conducted with the Kapolres Wakapolres, Head of BPJS Branch Office, Head of HR, Kasidokkes.

Abstract

From a public complaint perspective, according to the Ombudsman, the Indonesian National Police is one of the public service delivery agencies that "subscribes" to complaints. In fact, in the last few years Polri has always been in the top 8 to 5 nationally as the institution with which the most complaints have been made. To overcome this, the National Police Chief, General Listyo Sigit Prabowo, included 5 priority programs related to public services and handling public complaints among the 16 National Police Chief Priority Programs. Then on February 24, 2021 the National Police Chief also launched the Dumas Precision application and to further emphasize the importance of cross-functional and sectoral cooperation and synergy regarding handling public complaints, the Indonesian National Police Chief issued a Chief of Police Circular Number: SE/5/II/2021 dated February 24, 2021 concerning the National Police System. Information on Integrated Community Complaint Handling within the National Police. This research was conducted in 11 Polda and 54 Polres. Data collection was carried out by distributing questionnaires to people who had made complaints to the National Police and Dumas operators, FGD with key officials at the Polda and Polres, as well as FGD with operators of public complaint services. The results of the study show that the responsiveness, trustworthiness, transparency and accountability of public complaint services by the Police are at a moderate level. There are still many personnel, both in Polda and Polres, who do not understand the concept of the Integrated Dumas Service Center (SPDT) and its implementation. The majority of Polri personnel who were complained about/didumas complained about the occurrence of repeated examinations/holdings of cases with the same case, both by internal and external parties. In fact, many personnel still have to undergo inspections, even though the handling of the Dumas has been completed

Abstract

One of the determining factors in food security is the availability of agriculture water. Due to decreasing of rainfall and runoff, groundwater is one of the solutions for attaining agriculture's water needs. Groundwater has been depleted in the western region of Sragen Regency. It is necessary to investigate the groundwater level depletion in Sragen Regency so that production can be increased without overexploitation. MODFLOW-USG was used to simulate groundwater conditions mathematically. The model is based on current conditions and projected until 2033, with various scenarios for irrigation necessity which has 1, 0.8 and 0.7 l/s/ha that represented as conventional, System of Rice Intensification (SRI), and Alternate Wetting And Drying (AWD). For current conditions, model results show that groundwater level (GWL) decreased by 7.9 m from 1996 – 2019 without a scenario. Simulations from 2020 to 2033 using conventional water necessity show a decrease in GWL up to 2.585 m, 1.895 m for the SRI method, and 1.788 m for the AWD method. According to this result, the AWD water necessity is the most effective both in reducing groundwater table declining and maintaining plant productivity. However, the decreasing in GWL would occur as long as groundwater withdrawal continued, regardless of the scenario. Therefore, it is proposed to fulfill agricultural land’s water with other water resources such as reservoir or retention basins. Furthermore, there is a need for cropping patterns and scheduling that affect the amount of water demand, so water needs are met and do not over-exploiting the groundwater.Keywords: Groundwater, MODFLOW-USG, conventional, SRI, AWD
