Published: October 2022

Sungai Babon merupakan salah satu sungai di Semarang, Jawa Tengah yang dimanfaatkan untuk berbagai aktivitas manusia sehingga berpotensi menghasilkan limbah yang akan mencemari perairan. Perubahan kualitas air akibat pencemaran akan mempengaruhi persebaran dan struktur komunitas fitoplankton. Diatom (Bacillariophyceae) adalah salah satu kelompok fitoplankton yang tersebar luas di perairan karena memiliki daya adaptasi yang tinggi. Tujuan dari penelitian ini adalah mengetahui kondisi kualitas air dan struktur komunitas diatom (Bacillariophyceae) di Sungai Babon. Penelitian ini dilakukan di 5 stasiun yang tersebar dari hulu hingga hilir Sungai Babon pada bulan April dan Mei 2021. Variabel kualitas air yang diukur meliputi suhu, kecerahan perairan, pH, oksigen terlarut (DO), nitrat, dan fosfat. Hasil penelitian ini menunjukkan parameter kualitas air Sungai Babon masih sesuai dengan baku mutu PP RI No. 22 Tahun 2021 Kelas II tentang Penyelenggaraan Perlindungan dan Pengelolaan Lingkungan Hidup, kecuali kadar oksigen terlarut di Stasiun 5. Diatom (Bacillariophyceae) yang ditemukan di Sungai Babon berjumlah 17 genera. Diatom yang paling banyak ditemukan adalah Navicula, diikuti Synedra, Surirella, dan Melosira. Navicula adalah genus diatom yang ditemukan di semua stasiun penelitian dan memiliki kelimpahan tertinggi dengan persentase kelimpahan berkisar antara 13,82-52,83% dari kelimpahan total setiap stasiun. Diatom memiliki indeks keanekaragaman yang rendah, keseragaman tinggi (merata), dan dominansi rendah. Babon River is one of the rivers in Central Java that is used for various human activities so it has the potential to produce waste that will pollute the waters. Changes in water quality will affect the distribution and structure of the phytoplankton community. Diatoms (Bacillariophyceae) are a group of phytoplankton that is widely distributed in waters because they have high adaptability. The purpose of this study was to determine the condition of water quality and community structure of diatoms (Bacillariophyceae) in the Babon River. This research was conducted at 5 stations spread from upstream to downstream of the Babon River in April and May 2021. The water quality variables measured included temperature, water transparency, pH, dissolved oxygen, nitrate, and phosphate. The results showed that the water quality parameters of the Babon River are still following the quality standards of PP RI No. 22 of 2021 Class II, except for dissolved oxygen levels at Station 5. Diatoms (Bacillariophyceae) found in Babon River are 17 genera. The most common genus was Navicula, Synedra, Surirella, and Melosira. Navicula is a genus of phytoplankton found in all stations and has the highest abundance with a percentage from 13.82 to 52.83% of the total abundance of each station. Diatoms have a low diversity index, high similarity, and low dominance.

BISNIS SEBAGAI KEKUATAN POLITIK: KAJIAN PENGEMBANGAN STRATEGI KOTA SURAKARTA DALAM PENGEMBANGAN INDUSTRI PARIWISATA (2005-2012)
Authors: Harsasto Priyatno
Published: October 2022

The rapid shift from centralised–authoritarian to decentralised–democratic rule in Indonesia has been accompanied by a large shift in sub-national government policies across districts. Based on  case study in Surakarta city comprising business surveys and  in-depth interviews, this report argues that demand-side pressures from local business and associations as well as supply-side pressures from local government leaders can be attributed as the broad explanation for the Surakarta city’s performance in tourism industry. In Indonesia’s early transition to democratic governance, business pressures have been constrained by collective action problems and perverse political incentives. On the other hand,  local government leaders with good vision, have strong powers and new incentives for policy reform. Local leaders have been playing crucial role in shaping political arena for business as well as civil society. In the name of political inclusion, they invite civil society as well business groups to involve in policy making process. This study’s findings suggest that government leadership is an important policy determinant that can shape the interests of business and the people. The ability of the leader to  create economic growth has been determinant in bridging the interests of business as well as the society as a whole.
DEMOKRASI DALAM GENGGAMAN PARA PEMBURU RENTE (STUDI KASUS ASAHAN SUMATERA UTARA)
Authors: Rahmawati Desi
Published: October 2022

Vedi R. Hadiz’s concern on New Order’s strong and durable influence to current politics (old predatory interest/ durable capitalist oligarchy) is quite interesting. His thesis that Indonesian democracy is flawed due to old predatory interest rooted in New Order tends to be problematic in some ways as it ignores context as well as actors’ contribution. This writing, therefore, argues that Hadiz’s structural explanation does not work in all localities, even North Sumatra—his main research locus. Rather, it argues that explaining the correlation between democracy and predatory interest (rent seeking), one necessarily paying attention to specific logic (“abstract structure”) works in localities and actors’ consideration upon it.

This article aims to investigate the policy shift of local cultural management in Banyumas Regency during the Covid-19. The pandemic has brought a wide impact beyond the health issues including cultural activities that tend to be overlooked. The local culture of Banyumas was selected because local cultures other than Javanese somehow failed to be noticed by the experts since the New Order Era. This paper is library research that examines cultural policies. The result reveals that the Banyumas local culture has been managed by the local government of Banyumas through the culture and tourism office. In cultural activities, there are two patterns, namely cultural activities held by the Banyumas Regency government and cultural activities held by the village administration. During the pandemic, nonetheless, more activities are carried out by the village administration and local society. It shows that the social-cultural bond between the local people and the village administration is strong in the attempt of preserving their customs and traditions. The value of mutual assistance is a pivotal contribution to support the cultural activities amid the less favorable situation due to the Covid-19 pandemic. This outcome also confirms that a study of cultural policy cannot be separated from the necessity of understanding how the village administration as the lowest government unit plays a significant role in cultural preservation along with the local society.
The “Migration” of Terrorist Actors in Indonesia: From Male-Dominated Terrorist to the Emergence of Female Terrorist Migrant Domestic Workers

The ISIS group’s declaration in 2014, has inspired female extremists from various countries to join the terrorist group. At the end of 2016, two women were arrested by the Indonesian police for planning terror attacks in two different places. Both are former migrant domestic workers who returned from Hong Kong. This article investigates why women join terrorist groups, why male-dominated terrorist groups recruit women and what makes female migrant domestic workers who return to Indonesia as extremists willing to make a significant contribution to the terrorism movement in Indonesia. This research’s data collection technique is qualitative data collection, and document-based research through literature studies. This article utilizes Quintan Wiktorowicz’s three radicalisation concept phases: cognitive opening, religious seeking and socialisation. This study found that at least four reasons women become extremists, namely personal complaints, influence from family, relatives or lovers, ideological perceptions, and media use, facilitate the radicalisation process. Furthermore, strategic interests seem to be the answer to why terror groups involve women to achieve their goals. The acceptance of terrorist groups to involve women can be the reason why women migrant domestic workers are willing to make an immense contribution to terrorist groups. Their enthusiasm, financial capacity and international experience are expected to strengthen the terror movement in Indonesia. Both create a “mutually reinforcing” relationship that benefits both parties. Further research is needed with a sample of ordinary female extremists outside migrant domestic workers as a comparison to examine women’s motivations and group decisions to include these women in terrorist activities.

Salah satu indikator penting dalam perekonomian suatu negara adalah nilai tukar dari mata uang, dimana majunya suatu negara dapat ditentukan oleh kekuatan nilai mata uang negara tersebut. Nilai tukar yang berdasarkan pada kekuatan pasar akan selalu berubah disetiap kali nilai-nilai salah satu dari dua komponen mata uang berubah. Dengan mampu meramalkan perubahan nilai tukar mata uang tersebut maka dapat ditentukan harga yang tepat untuk menukarkan mata uang para pemilik modal ke dalam bentuk mata uang lain. Proses peramalan/ prediksi dapat dilakukan dengan menggunakan arsitektur jaringan adaptive neuro fuzzy inference system (ANFIS) terhadap data kurs. Data kurs yang digunakan merupakan data kurs nilai jual pada jenis kurs Dolar Amerika, Dolar Singapura dan Euro sebanyak 110 data untuk tiap-tiap jenis kursnya dari periode 1 Agustus 2017 hingga 9 Januari 2018. Hasil pengujian menunjukkan bahwa kombinasi terbaik parameter untuk kurs Dolar Amerika adalah laju pembelajaran sebesar 0,1; maksimal epoch sebesar 10000; jumlah data pelatihan sebanyak 80%; target error sebesar 0,001 dengan perolehan nilai Mean Absolute Percentage Error (MAPE) sebesar 0,41. Hasil pengujian menunjukkan bahwa kombinasi terbaik parameter untuk kurs Dolar Singapura adalah laju pembelajaran sebesar 0,2; maksimal epoch sebesar 10000; jumlah data pelatihan sebanyak 80%; target error sebesar 0,001 dengan perolehan nilai Mean Absolute Percentage Error (MAPE) sebesar 0,12. Hasil pengujian menunjukkan bahwa kombinasi terbaik parameter untuk kurs Euro adalah laju pembelajaran sebesar 0,5; maksimal epoch sebesar 10000; jumlah data pelatihan sebanyak 80%; target error sebesar 0,001 dengan perolehan nilai Mean Absolute Percentage Error (MAPE) sebesar 0,38. Tingkat akurasi untuk prediki kurs Rupiah terhadap Dolar Amerika sebesar 99,58%, terhadap Dolar Singapura sebesar 99,87% dan terhadap Euro sebesar 99,62%.

Politeknik Negeri Semarang menerima mahasiswa baru melalui beberapa jalur penerimaan.Salah satunya adalah jalur Penelusuran Minat dan Kemampuan Politeknik Negeri (PMDK-PN).Berdasarkan survei dan wawancara dengan Kepala UPT TIK Politeknik Negeri Semarang, masih terdapat kendala dalam seleksi jalur PMDK-PN, yaitu format data nilai akademis yang berbeda dari tiap sekolah, proses seleksi yang belum terotomatisasi, dan perhitungan nilai ranking yang terus berubah. Berdasarkan masalah tersebut, diperlukan sebuah sistem pendukung keputusan untuk seleksi jalur PMDK-PN. Terdapat beberapa metode yang digunakan untuk mengembangkan sistem pendukung keputusan. Metode Multi Objective Optimization on the Basis of Ratio Analysis (MOORA) dan metode Analytic Hierarchy Process (AHP) termasuk dalam metode tersebut. Pada penelitian ini menggunakan metode AHP untuk menghitung bobot kriteria penerimaan, dan metode MOORA untuk menentukan ranking calon mahasiswa. Kriteria yang digunakan yaitu data rata-rata nilai rapor semester 1 – 5, nilai prestasi non-akademik, akreditasi sekolah, dan rata-rata peringkat banding jumlah siswa semester 1 - 5. Analisis hasil dilakukan menggunakan 1774 data sampel, yang terdiri dari 988 data siswa SMA/MA dan 786 data siswa SMK/MAK. Dari data tersebut, jumlah siswa yang akan diambil yaitu 348 siswa SMA/MA dan 96 siswa SMK/MAK. Saat hasil penerimaan sistem perankingan dan hasil penerimaan Politeknik Negeri Semarang dibandingkan, terdapat 266 siswa SMA/MA, atau sekitar 76,4% yang sama-sama diterima. Sedangkan untuk siswa SMK/MAK, terdapat 57 siswa, atau sekitar 59,4% yang sama-sama diterima. Analisis hasil menunjukkan bahwa saat bobot kriteria sistem diaplikasikan pada kedua metode perhitungan, hasil yang diberikan adalah siswa pada hasil penerimaan sistem perankingan memiliki nilai akhir yang lebih besar dari siswa pada hasil penerimaan Politeknik Negeri Semarang.
