Abstract

This research aims to determine the costs required to build a guard post building in the border area of Papua, Indonesia and Papua New Guinea. It is hoped that this research will contribute to improving the national defense, especially regarding the construction of guard posts in national border areas. This research discusses the construction of the guard post by describing the volume of work and the planned cost budget, and the data collection methods used are primary and secondary data. In this research, guard post drawings were planned according to the standards of the Indonesian Army and supporting data in the form of Unit Prices for Goods and Services (SHBJ) in the Papua region, as well as the Ministry of PUPR's Unit Price Analysis Guidelines. Apart from that, the type of work along with the volume of work is arranged followed by an analysis of the unit price of each job. Then the Cost Budget Plan (RAB) is calculated to get the total price for each job. Thus, the total cost required to build a guard post building on the Papua border is IDR 119,441,000.00. In the future, it is hoped that this research can become a reference for building guard posts around the Papua border area.

Abstract

The earthworm Eudrilus eugeniae (African Night Crawler) can be used as a raw material for making protein hydrolysates. Hydrolysis of earthworms using papain enzyme produces peptides that have bioactivity as antioxidants. Antioxidant activity in earthworm hydrolysate is caused by phenolic compounds that have an important role in neutralizing free radicals. This study aims to determine the effect of earthworm concentration and papain enzyme concentration on soluble protein, total phenolic content, and antioxidant activity. This study used the Randomized Block Design (RBD) method arranged with two factors, namely earthworm concentration (20% 30%, and 40% (w/v)) and papain enzyme concentration (8%, 10%, and 12% (w/v)) with three replications. Data analysis used Analysis of Variance (ANOVA) and continued with the DMRT test. The results showed that earthworm concentration, papain enzyme concentration, and the interaction between the two factors had a significant effect (p<0.05) on the test results of soluble protein, total phenolic content, and antioxidant activity. The treatment with earthworm concentration (40% (w/v)) and papain enzyme concentration (12% (w/v)) produced the highest mean soluble protein, total phenolic content, and antioxidant activity of 11.47%, 23.07 mg GAE/mL hydrolysate, and 3301.42 ppm.

Abstract

This study presents a comparative evaluation of machine learning models for sentiment analysis on Tokopedia user reviews written in the Indonesian language. The objective is to assess the effectiveness of three algorithms—Support Vector Machine (SVM), Random Forest (RF), and Multilayer Perceptron (MLP)—in classifying customer sentiments extracted from Tokopedia reviews on Google Play Store. The dataset, collected between January and October 2025, consists of 10,236 unique entries after preprocessing, which included text cleaning, case folding, tokenization, stopword removal, normalization using a verified Indonesian word normalization dictionary, and optional stemming with the Sastrawi library. The reviews were divided into positive and negative categories based on rating polarity (4–5 stars as positive; 1–2 stars as negative).Each model was evaluated using both hold-out validation (80:20 split) and 5-fold cross-validation, employing metrics such as accuracy, precision, recall, and F1-score. Experimental results indicate that the SVM achieved the highest accuracy of 0.88, outperforming Random Forest (0.85) and MLP (0.83). These findings demonstrate that SVM performs more robustly on sparse TF-IDF vector features and is more resistant to noise within informal Indonesian expressions. The research further discusses the linguistic challenges inherent in Indonesian sentiment analysis, including code-mixing, abbreviations, and non-standard words, while proposing preprocessing strategies to mitigate them.The outcomes of this study contribute to enhancing the reliability of sentiment-based decision support systems in Indonesian e-commerce platforms. The methodological framework developed here can serve as a baseline for future work involving hybrid or deep-learning approaches such as LSTM or IndoBERT for improved contextual understanding.

Abstract

Perkembangan teknologi komunikasi mendorong kebutuhan jaringan nirkabel yang luas, handal, dan efisien. Antena sebagai komponen utama komunikasi jarak jauh dituntut berkembang dalam bentuk dan fungsi. Teknologi beamforming kini banyak digunakan karena mampu mengarahkan sinyal secara spesifik untuk mengurangi gangguan, meningkatkan kualitas, dan efisiensi daya. Namun, antena konvensional masih memakai pola radiasi menyebar, menyebabkan pemborosan daya dan interferensi. Sementara itu, pengembangan antena kompleks sering terkendala biaya dan material. Penelitian ini merancang antena dengan arah pancaran sinyal yang dapat diatur tanpa mengubah bentuk atau posisi antena secara fisik, namun tetap ekonomis dan efisien. Solusi yang diusulkan adalah antena mikrostrip switchbeam frekuensi 5,8 GHz yang mengubah arah pancaran berdasarkan port input aktif. Antena menggunakan patch fraktal Koch Island berbahan tembaga dan substrat FR-4. Desain terdiri dari 4 port yang dikombinasikan melalui power combiner 4:1 dan dikendalikan RF switching. Pencatuan sinyal memadukan teknik feedline dan coaxial, dengan desain melalui CST Studio Suite 2019. Hasil pengujian menunjukkan return loss < -10 dB, VSWR 1,160–1,235, bandwidth 1,096–1,192 GHz, dan mutual coupling < -20 dB. Meskipun gain belum mencapai 6 dBi, antena tetap menunjukkan performa sesuai harapan. Kata kunci— antena, fraktal, mikrostrip, pola radiasi, switchbeam.

Abstract

In the Cijurey Dam Package I conduit construction project, formwork technology is an important aspect because it is entirely the responsibility of the contractor, so the implementation risks need to be minimized. Initially, the concrete casting method used conventional formwork that was made directly at the project site. However, developments in the construction world demand more efficient methods, leading to the emergence of alternatives such as the use of prefabricated formwork. One type used is sliding formwork. This study aims to evaluate the cost and time effectiveness between conventional formwork and sliding formwork, as well as analyze the reasons for their selection in the Cijurey Dam Package I conduit work. The research method was carried out by calculating the estimated cost and duration of conventional formwork, then comparing the results with the data on the use of sliding formwork in the project. The results show that the Cijurey Dam Package I Construction Project used sliding formwork at a cost of Rp 185.185,00 per square meter, with a cost difference of Rp 342.819.286,34 or about 12,37% cheaper than the calculation using conventional formwork, which averaged - average of Rp 211.332,06. In addition to cost and time considerations, sliding formwork has a faster construction time of 2 hours per tunnel block conduit compared to conventional formwork.

Abstract

This paper deals with the vehicle routing problem with multiple trips and time windows (VRPMTTW). The problem combines two features to the basic vehicle routing problem (VRP): multiple trips and time windows. The basic VRP and its variants fall into hard combinatorial optimization problems. Therefore, many heuristics have been developed to solve large problems. Local search (LS) is one of the heuristics using a neighborhood structure in order to find a better solution. This paper focuses on the comparative study of neighborhood structures applied in LS for the VRPMTTW. Two classes of neighborhood structures are compared: Tour-based and permutation-based neighborhood structures. The tour-based neighborhood structures are the neighborhoods in which the moves are performed on the solution represented by a set of tours. The permutation-based neighborhood structures are the neighborhood structures in which the moves are carried out on the solution represented by a permutation of customers. Comparing the performance of the neighborhood structures uses two responses: (1) relative improvement in the objective function value and (2) computation time. The first response is used to measure effectiveness, while the second is used as efficiency. Based on the computational experiment results, it is generally revealed that the permutation-based neighborhood structures used in LS are more effective than the tour-based neighbourhood structures. However, the permutation-based neighborhood structures are less efficient because they give higher computation times.
