Abstract

Vibrio cholerae is an infectious agent causing cholera disease with a high prevalence in various developing countries. V. cholerae is a pathogen with broad spectrum host that can infect humans and animals, especially aquaculture. The existence of this disease in Indonesia has long been identified in several outbreaks. Various reports in Indonesia have succeeded in finding the existence of V. cholerae in the environment, aquaculture, food and beverage, as well as in clinical cases of V. cholerae infection. The presence of V. cholerae in environment such as water source is commonly related with contamination. However, V. cholerae can be found in aquatic environment as this environment is natural habitat for V. cholerae. Thus, aquaculture is prone to be infected with V. cholerae because the presence of this pathogen is abundant in aquatic environment. Contaminated food and beverage are associated with hygiene and sanitation and human is commonly infected after consuming contaminated food or beverage. This brief review has the main focus to discuss the existence of V. cholerae from environmental to clinical aspects found in Indonesia.

Abstract

Maggot comes from the Black Soldier Fly insect which is very active in eating a variety of organic waste. Maggot is able to process organic waste up to 52.2 kg per day. Indonesian waste dominated by organic species is 40 million tons in 2019 where 17.94% is produced by traditional markets (7 million tons). Based on BPS data, Traditional markets produce 1 ton of waste per day. By the ability of maggot to process waste, a 60 x 40 meter building is needed. Aside from being an organic waste solution but also as a producer of maggot with high protein, maggot flour and compost, it will add economic value. Organic waste production in Indonesia which continues to increase has the potential for maggot production to be continuous so that it can replace fish meal or conventional animal feed in terms of continuity. Maggot has a crude protein content of 42% so it is very good as a substitute for fish meal which is always imported. Maggot is also thought to have potential as a substitute for the MBM ration. Research shows that maggot flour can replace 75% of fish meal as an abdominal ration. The compost produced by maggot also has a greater NPK value than Em4 and cow dung, so that it has the potential to become a quality NPK fertilizer. It can be concluded maggot as an organic waste solution and potentially as a substitute for conventional sustainable feed.

Abstract

Kegiatan penelitian tidak seharusnya hanya dibatasi pada hasil akhir yang berupa publikasi. Penelitian terdiri dariproses bertahap dan sering kali membutuhkan usaha yang sangat besar di tiap tahapan sebelumnya. Revolusiindustry 4.0 yang menekankan pada ketersediaan data dan informasi yang beragam kepada publik, jugamengubah cara peneliti dalam hal pengelolaan data penelitian. Sekarang ini peneliti dapat berkolaborasi dalampenggunaan data dengan adanya akses terbuka data penelitian (open research data). Terdapat perubahanparadigma, di mana penelitian bukan lagi hal yang sifatnya individu, melainkan kolaborasi dan multidisiplin yangdapat membedah suatu hal dari banyak sisi. Hal inilah yang memicu Pengelolaan Data Penelitian (Research DataManagement (RDM)), sebuah konsep yang memungkinkan peneliti untuk menyimpan dan sekaligus membukaakses data penelitian sebesar-besarnya sehingga orang lain dapat mengakses dan memungkinkan untukberkolaborasi, pertukaran ide, dan penggunaan ulang untuk tujuan yang lain. Pada konsep RDM, di mana dataterbuka untuk umum, data penelitian mengenai suatu komunitas dapat dibahas dari berbagai sudut pandang ilmudisiplin. Studi ini merupakan studi awal yang bertujuan untuk mengidentifikasi praktek RDM di perguruan tinggi diIndonesia. Penelitian ini berupaya melakukan perbandingan ketersediaan platform RDM di Indonesia denganobservasi pada situs web 10 perguruan tinggi terbaik di Indonesia dan studi literatur sistematis terhadapketersediaan platform RDM jika akan diimplementasikan di Indonesia. Hasil dari penelitian ini ditemukan bahwabelum ada perguruan tinggi yang diteliti yang sudah menerapkan platform RDM di Indonesia. Sekarang ini banyakperguruan tinggi yang sudah mapan dalam pembuatan sistem informasi RDM di seluruh dunia. Oleh karena itu,hasil dari penelitian ini bisa dijadikan bahan pertimbangan oleh Kementerian Riset dan Pendidikan Tinggi RI(Kemenristek DIKTI RI) dan perguruan tinggi lainnya dalam mengembangkan sistem RDM yang ideal. Research should not be limited to publication and publishing. Research covers range of activities that usually needhigh efforts. Industry 4.0, which emphasized on the availability of integrated data and information have changedresearchers in managing their research data. The open research data has enabled researchers to collaborate andreuse available data to solve many problems on society. There is a paradigm shift that research is no longer seenas individual private activity that researcher take hold of the data for themselves, but into more collaborative andmultidisciplinary. These kinds of activities coined a term of the Research Data Management (RDM), a servicewhere researchers could put their research data to collaborate, share, and maximally reuse the data for otherpurposes. In RDM, research data is publicly available that can be learned by other scientists in many differentbackgrounds. This study is a pilot study that has objective to identify the RDM practice in Indonesian universities.This study is a comparison study by identifying the availability of RDM platform and information systems throughliterature review and observation of websites of the best 10 Indonesian universities. RDM has been implementedby most universities in many developed countries. From this study, we could know that there are no Indonesianuniversities that has implemented RDM yet. Therefore, this study could be used as basis for the IndonesianMinistry of Research and Higher Education (Ristek DIKTI) and other higher education institutions in thedevelopment of ideal Research Data Management Platform and Information Systems.

Abstract

Artikel ini membahas membatik sebagai keterampilan yang harus dimiliki oleh pelajar SMP dan SMAdi daerah-daerah yang memiliki budaya membatik di Indonesia. Metodologi penelitian yang digunakanadalah metode kualitatif, kemudian instrumen penelitian yang digunakan adalah observasi lapangandan media sosial, studi literatur, dan wawancara. Membatik merupakan keterampilan yang seyogyanyadimiliki oleh sebagian besar masyarakat Indonesia, namun dewasa ini keterampilan dalam membatikdan orang-orang yang terampil membatik semakin berkurang, karena proses regenerasi yang tidakdilembagakan dan dipersiapkan secara matang oleh pemerintah. Sejalan dengan alasan tadi, minatpara pelajar untuk belajar membatik pun berkurang, terutama dalam mengapresiasi warisan budayaleluhur. Demikian pengembangan kurikulum tingkat SMP dan SMA dengan menambahkanketerampilan membatik sebagai muatan lokal (mulok), akan memberikan pemahaman yang lebih baikkepada generasi penerus dalam menjaga budaya membatik (tulis dan cap) sebagai warisan budayayang telah diakui oleh UNESCO. Penulis berpendapat dengan diadopsinya inovasi ini dalam kurikulumpendidikan akan membawa dampak positif bagi Indonesia. Demikian, tanpa adanya kerjasama dalammembangun kesadaran untuk melestarikan budaya leluhur antara Kementerian Pendidikan danKebudayaan RI dengan setiap lembaga pendidikan yang berada di bawah tanggung jawabnya tidakakan terwujud suatu proses transfer nilai-nilai budaya yang berkesinambungan. This article write over membatik as skill which must know-how by high school students at regions whohave membatik tradition in Indonesia. Methodology Research which will use qualitative and alsoobservation, study literature and interview as instruments. Membatik skill which must have to allIndonesian people who have batik tradition, as time goes by membatik skill and the batik expert morediminish, because the process regeneration which not create institute for maintain the tradition andpreparation for the future by government. Accordance with the statements, interest from students forlearning membatik diminish, especially in appreciate cultural heritage. That developing of curriculum inJunior High School and Senior High School with adding skill membatik as mulok (local content), willgive understanding more better to the new generation in to protect the tradition membatik (written andstamp batik) as prestigious cultural heritage which one avowed with UNESCO. This article be of theopinion with adopted this innovation in education curriculum will brings the positive impact for Indonesia.Thus, without existence partnership in development the understanding for conserve prestigious culturebetween Ministry of Education and Culture of RI and every institution education it will not reach thesustainable cutural values.

Abstract

Pemerintah telah merumuskan Kebijakan Energi Nasional (KEN) dengan fokus pengembangan energi baruterbarukan (EBT) untuk mengantisipasi habisnya sumber energi fosil di masa mendatang. Dalamimplementasinya, pemerintah menghadapi kendala baik dari segi anggaran maupun teknologi yang dimiliki.Pendanaan dari swasta terutama dalam bentuk Foreign Direct Investment (FDI) sangat diperlukan. Penelitian inibertujuan untuk melihat sejauh mana daya tarik investasi di sektor kelistrikan berbasis EBT. Metode penelitianyang digunakan menitikberatkan pada studi literatur berupa analisis terhadap kebijakan pemerintah dalammenciptakan iklim investasi bidang green energy sektor kelistrikan. Berdasarkan hasil analisis dapat disimpulkanbahwa iklim investasi saat ini masih belum mampu mendorong implementasi green energy di Indonesia. Hal initerbukti dari skor RECAI Indonesia yang masih rendah (peringkat ke-36 dari 40 negara yang disurvei). Beberapakebijakan pemerintah telah mendukung iklim investasi di sektor green energy diantaranya terkait keterbukaankepemilikan modal asing hingga 100%, fasilitas tax allowance dan tax holiday untuk investasi di sektor greenenergy. Akan tetapi, terdapat pula beberapa kebijakan yang perlu dirumuskan kembali seperti kebijakanpenentuan harga beli produk energi kepada para investor dan kebijakan mekanisme bagi PengembangPembangkit Listrik (PPL) dengan sistem pemilihan langsung yang dinilai masih belum efisien sehingga menjadikendala pelaksanaan investasi di sektor green energi. Indonesian government has formulated a National Energy Grand Policy which is focused on renewableenergy/green energy development to anticipate the run-out of the finite reserve of fossil energy resources. Thereare two major challenges faced by the government on implementing this policy which are the advanced technologyrequired and the budget constraint. Foreign Direct Investment (FDI) becomes a potential solution yet theperformance of FDI realization in green energy sector these past years is still under national target. The objectiveof this research was to analyse Indonesia’s investment attractiveness specifically on green energy-basedelectricity sector. The method used on this research was literature study focusing on the government policies thataffected Indonesia’s investment climate on that particular sector. Based on the analysis result, these policies ingeneral haven’t been able to elevate investment atrractiveness proven by Indonesia’s RECAI rank that is fairly low(the 36th out of total 40 assessed countries). Although the government has implemented several policies such as:liberation on foreign capital owners up to 100%, tax allowance and tax holiday for green energy sector, some otherfundamental policies i.e. the pricing formulation and the purchasing mechanism in fact are potentially harmful forthe investors. Moreover the frequently changed and, at some cases, lack of consistency, regulations often seenas a major barrier by investor specifically on the big scale investment.

Abstract

PT Riung Mitra Lestari adalah salah satu perusahaan kontraktor penambangan baru di Indonesia yang didirikan pada tahun 2006. Diidentifikasi bahwa Riung membuat prediksi permintaan (bulanan) untuk menentukan jumlah stok yang 'tepat'. Namun, ‘tingkat akurasi’ metode peralaman yang digunakan oleh Riung tidak dapat diukur, sementara meningkatkan akurasi peralaman dapat meningkatkan tingkat kinerja perusahaan (yaitu meminimalkan kemungkinan kehabisan persediaan dan inventaris yang berlebihan). Laporan ini bertujuan untuk menemukan metode prediksi terbaik bagi Riung untuk mengelola kontrol inventaris suku cadangnya; yang dimulai dengan mengelompokkan suku cadang menggunakan metode analisis ABC untuk menentukan penanganan pengendalian persediaan yang tepat untuk setiap kelompok. Data menunjukkan bahwa ada 37 suku cadang di Riung yang termasuk dalam kategori A, oleh karena itu diperlukan kebijakan yang lebih ketat. Hal ini menjadi dasar untuk memilih kategori A sebagai objek utama analisis dalam penelitian ini. Penelitian ini akan membandingkan tiga metode prediksi, Moving Average (MA), Weight Moving Average (WMA) dan Single Exponential Smoothing (SES). Kinerja setiap metode prediksi dinilai dengan menghitung nilai kesalahan prediksi (MAD, MSE, MAPE, TS). Diketahui bahwa ada empat suku cadang dengan metode Moving Average sebagai metode prediksi terbaik, delapan suku cadang terbaik dengan menggunakan WMA dan sisanya 25 suku cadang terbaik dengan metode Single Exponential Smoothing (SES) PT Riung Mitra Lestari is one of the new mining contractor company in Indonesia founded in 2006. It is identified that Riung creates (monthly) demand forecasting for determining its ‘proper’ stock quantities. However, the accuracy level of forecasting method used by Riung cannot be measured, while improving the forecasting accuracy may rise the performance level of company (i.e. minimizing the probability of the stock out and excessive inventory). This report is aimed to find the best forecasting method for Riung to manage its spare parts inventory control; which is began by grouping spare parts using ABC analysis method to determine the appropriate inventory control handling for each group. Data showed that there are 37 spare parts in Riung that belong to category A, hence a more stringent policy is required. This correspondingly became the basis for selecting category A as the main objects of analysis in this study. The research will compare three forecasting methods, Moving Average (MA), Weight Moving Average (WMA) and Single Exponential Smoothing (SES). The performance of every forecasting method was assessed by calculating the value of forecast errors (MAD, MSE, MAPE, TS). It is known that there are four spare parts with Moving Average method as the best forecasting method, eight spare parts is best by using WMA and the rest 25 spare parts is best with Single Exponential Smoothing (SES) method.
