The use of social media is already powerful and difficult to avoid. Social media users are not only limited to the general public, but also public figures and even economic actors who use social media as a means of marketing. In every post from the account owner, there will always be followers who can give likes and comments. Unfortunately, not all comments are related to the uploaded post. One of the most annoying comments is spam comments. Spam comments are comments that are not clear and contain about business (promos / selling), links or various other things that are promoting something. Using the Naive Bayes algorithm, this study wants to identify spam comments, especially on Instagram social media. Where the data is retrieved using the tools provided by Google.

Oral health is an important aspect in maintaining the quality of life of the elderly. However, the elderly often face challenges in maintaining oral hygiene due to decreased physical abilities, changes in cognitive status, and lack of knowledge and access to dental health services. This study aims to identify factors that influence oral hygiene in the elderly and to develop an effective community-based intervention to improve oral hygiene among the elderly. The methods used in this study included a survey of knowledge, attitudes, and oral hygiene practices before and after counseling, as well as direct observation of oral hygiene in 50 elderly in the local community. The intervention was carried out through counseling, training, and providing support from family and community. The results showed a significant increase in knowledge of the elderly, from 60% before counseling to 85% after. Positive attitudes also increased, with more than 80% of the elderly showing a stronger intention to maintain oral hygiene independently. Oral hygiene practices also improved, with 75% of participants reporting brushing their teeth at least twice a day after the intervention, compared to 40% before the intervention. In addition, family and community support play an important role in facilitating these behavioral changes. The conclusion of this study is that a comprehensive community-based intervention is effective in improving oral hygiene in the elderly.

Fresh or rotten meat is a different matter. Damage to the meat will produce a distorted odor, mucus, discoloration in certain areas and an undesirable taste due to the formation of metabolism. The odor is described as fishy, ​​rotten, containing sulfur and like ammonia. In this research, the author discusses a system for identifying the condition of meat based on the odor that arises from meat in three states, namely odorless odor, fresh odor and rotten odor. Fresh odor is taken from meat odor that is within 1 (one) day after being cut and rotten odor is taken from meat odor that is on the 2nd day. In this study, the test sample meat was placed in a closed container at room temperature for 2 days. Data was taken for 2 days from meat odors of known type. The sensor array consists of eight sensors made of conducting polymer material. The polymer materials used are silicon DC-200, PEG-20M, 0V-101, 0V-17, DEGA, PEG-200, PEG-1540, and PEG-6000 mixed with Carbon black. A two-layer artificial neural net consisting of eight input nodes and three output neurons, was trained using the Kohonen algorithm with a training process that was completed in 4 iterations. From 20 tests, 10 times exposure to steam from fresh odor and 10 times exposure to steam from rotten odor, carried out alternately, it was found that the system failed twice. Thus, the system success percentage reached 95 percent.

Sektor pertanian, terutama produksi tanaman pangan merupakan pilar perekonomian di Indonesia dengan sentra produksi berada di Nusa Tenggara. Salah satu penyebab penurunan produksi tanaman pangan adalah kekeringan yang disebabkan oleh perubahan iklim. Kekeringan dapat dihitung dengan Standardized Precipitation Index yang merupakan indeks untuk mengukur tingkat keparahan kekeringan suatu wilayah. Tingkat keparahan kekeringan suatu wilayah dapat mencapai nilai tertinggi yang dapat digunakan untuk memperkirakan periode kejadian kekeringan yang terjadi secara berulang. Selanjutnya hasil estimasi tersebut dapat digunakan untuk memperoleh nilai Return Period yang merupakan rata-rata waktu kekeringan yang terjadi dengan menentukan keparahan kekeringan maksimum. Untuk mengantisipasi kekeringan yang terjadi secara berulang, tujuan dari penelitian ini adalah melakukan identifikasi karakteristik kekeringan dari Return Period berdasarkan profil geografis Nusa Tenggara. Data yang digunakan adalah data observasi curah hujan bulanan selama periode tahun 1985 sampai 2014 yang menggambarkan kejadian kekeringan yang telah terjadi untuk masa sekarang dan data skenario curah hujan bulanan selama periode tahun 2016 sampai 2100 berdasarkan Representative Concentration Pathways yang menggambarkan iklim di masa akan datang. Hasil analisis data menunjukkan bahwa Return Period secara geografis memberikan gambaran untuk berbagai wilayah. Pada wilayah karakteristik iklim lebih basah terlihat adanya pengurangan curah hujan, sedangkan wilayah karakteristik iklim lebih kering tidak mengalami pengurangan curah hujan yang signifikan. Secara umum dapat diketahui bahwa beberapa tahun ke depan prediksi kekeringan Pulau Nusa Tenggara menunjukkan tingkat keparahan kekeringan yang tidak terlalu parah dengan periode berulang yang lebih sering terjadi.
