Abstrak: Sragen district archives system is the system that used to store archived data. In this archives system, the searching is based on data or a summary disposition from the archives. Because this search result is limited, this research makes search engine for regional archives system that is based on the contents of digital archives, especially Microsoft Word. This search engine is using vector space model for weighting and cosine similarity. Stemmer used in this research is stemmer based on KBBI. Evaluation is using recall and precision of queries that has been determined. The calculation of average precision (AVP) is done because of some queries are used in this evaluation. AVP measuring is calculatd based on 11 standard recall levels. Evaluation result from the search engine is relevant documents that appropriate with the sequence relevance. The value of average precision got from 10 queries is 0.896, scale from 0 to 1. The precision of the search engine performance is affected by the stemmer. Stemmer KBBI creates smaller index size, but it decreases the precision. Stemmer KBBI decreases the precision, because of search by using basic words .

Judul: Analysis of Stress  Causative Factors in Axolotls (Ambystoma mexicanum) Based on Skin Color
Abstrak: Populasi alami axolotl telah mengalami penurunan yang mengkhawatirkan dalam beberapa dekade terakhir. Dampak perubahan lingkungan dapat berpengaruh pada kesehatan axolotl. Suhu yang melebihi batas optimum dapat menyebabkan stres pada axolotl hingga kematian yang berdampak pada penurunan populasi. Suhu perairan yang optimum bagi axolotl yaitu 16–20 °C. Oleh karena itu, dilakukan penelitian untuk mempelajari faktor yang dapat memengaruhi keadaan stress pada axolotl. Penelitian ini dilakukan pada sembilan sampel axolotl dengan tiga warna kulit berbeda yaitu merah muda (leucystic), kecoklatan berbintik hitam (marble), dan kuning (golden) yang berusia 4 bulan. Axolotl diberi 3 perlakuan selama satu minggu, terdiri dari pemberian makan sehari sekali, suhu ruang ±26 °C, dan penggantian air satu kali seminggu. Dari sampel darah yang digunakan pada serangkaian uji hematologi menunjukkan bahwa hemoglobin dan hematokrit berada pada batas normal, sedangkan total sel darah merah melebihi batas normal. Sedangkan total sel darah putih pada perlakuan pakan dan penggantian air dibawah batas normal. Axolotl marble lebih toleran terhadap cekaman ditandai dengan indikator stres pada setiap perlakuan yang baru muncul pada hari ke 6. Axolotl golden paling tidak toleran terhadap cekaman berdasarkan kemunculan stres pada hari ke 3. Faktor yang paling memengaruhi stres axolotl pada penelitian ini yaitu kualitas air., The natural population of axolotls has experienced concerning declines in the last few decades. The impact of environmental changes can affect the health of axolotls. Temperatures exceeding this optimal range can induce stress in axolotls, potentially leading to death and population decline. The optimal water temperature for axolotls is between 16–20 °C. Therefore, research has been conducted to study factors that can influence stress condition in axolotls. This research was carried out on nine axolotl samples with three skin colors: pink (leucystic), brown with black spots (marble), and yellow (golden), all of which was four months old. The axolotls were subjected to 3 treatments over a week, including once-daily feeding, room temperature of ±26 °C, and weekly water changes. From blood samples used in a series of hematological tests, showed that hemoglobin and hematocrit were within normal limits. Meanwhile the total red blood cell count exceeded normal and the total white blood cell count was below normal in the feeding and water change treatments. Factors influencing axolotl stress include water cleanliness and quality. Marble axolotls showed greater tolerance to stress, as indicated by stress indicators emerging on day 6 of each treatment. Golden axolotls were the least tolerant to stress, with stress indicators appearing as early as day 3.
