Problems on raw material inventory in food sector small scale industry have been of classical and yet no solution is achived. Specific characteristics found out, such as seasonal, perishasble, and post harvest losses have a significant influence on set up, distribution and warehousing cost. Consequence price fluctuation was observed. Excessive storage capacity means ineffective capital usage, contrarily, too low storage capacity can strike productive line lead to customer unsatisfaction. Optimum model approach on inventory has been taken using constant consideration on several storage and production planning characteristics. Optimum inventory model was developed through direct field observation on individual characteristic of raw materials and its fullfliness characteristic and their link to production planning. QS Software was used to solve EOQ analysis. The object research consist of 4 kinds of small scale industries, that are : emping melinjo (Gnetum g nem on), geplak, tofu (traditional food of soybean material) anda bakery small industries. The result shown that the inventory model of small scale industries Is affected by production rate. Case on emping melinjo industries, the inventory model consist of: (i) inventory model based on lead time greater than zero (ii) in ven tory model based on tolerance of raw material-shortage and (iii) inventory model based on constant production rate (replenishment model). Using the inventory model optimized in this research, raw material distribution controlled by government can be improved. Analysis show that the reorder point and order interval can be reduced (in cased of sugar and flour raw material). Fluctuation pricing of raw material provoque augmentation of total cost and order interval (in case of coconut raw material).

Mechanical damages of fresh fruits may happen in traditional packaging methods. The aim of research is to find some alternatives methods to reduce the mechanical damage during transportation. The variable used in the study are vibration and drop test, and the study was implemented for avocados. mangoes, bananas, and papayas. Using equivalent bruise index percentage, it is known that the packaging models suggested are capable to reduce the mechanical damages (% EBI) from 15,01%-22,33% through 1,57%-9,17%. The result obtained give alternatives for each commodity. The best packaging model for mangoes is the corrugated cartoon, followed by the wooden box V type, the plastic basket and traditional packaging (bamboo basket). Where as for avocados. the best packaging model is the plastic basket, followed by the corrugated. On the other hand, the corrugated cartoon is the best for papayas, followed by the wooden box V type, the plastic basket and traditional packaging (partition). The final result of the result suggests that the wooden box V type is the best for all commodities. This packaging uses a linked hinge which is easier for returning distribution, and surely it needs only little of space on transportation vehicles.

Rice is a vital commodity in Indonesia because it is the main staple food for most Indonesian people. Balancing supply and demand of rice in Indonesia is complex and has possibly led to polemics, even though the production of rice in Indonesia tends to increase. An analysis of the supply-demand for rice commodity is, therefore, necessary as an effort to improve the national rice condition along with the logistics and supply chain point of view. This study aims to analyze the supply chain risk management of rice to provide recommendations on improving rice supply chain performance on each tier. This study was undertaken at Demak and Sleman Districts, Indonesia. In-depth interviews were used to enrich the information from the respondents along the supply chain. In this study, tiers on the supply chain of rice mainly consists of farmers, collectors who also acts as traders, and retailers. Meanwhile, the role of government is represented by The Indonesia Logistics Bureau (BULOG). The different supply chain pattern could be identified from the role of middleman in each province. This study uses ISO 31000:2009 standard for analyzing the risk in each tier along the supply chain. Based on the risk analysis, on-farm activity plays a vital role in transferring risk along the supply chain in terms of quality and quantity. Risk mitigation of each tier was explored in this study.

The problems associated with rice production in Indonesia appear very complicated, due to poor management of the sufficient national rice stock and various unfavorable public policies. Recently, government’s directives on rice importation instigated polemics from several interests, as a result of inappropriate decisions on general rice production, with possible yearly increment. Therefore, there is need to embrace strategy development to balance demand and supply. The purpose of this study was to analyze the rice supply chain in Demak and Sukoharjo, Central Java Province, in an effort to provide effective and collaborative distribution policies at individual levels. In addition, in-depth interviews were conducted for 98 respondents in a bid to acquire relevant and current information for the conceptual framework development. Furthermore, sampling methodologies, termed purposive and snowballing, were applied, followed by the preparation of interview guidelines. The results showed the farmers obtained the lowest revenue margin among other tiers, while several technical challenges were also identified. Consequently, the activities of middlemen with excessive dominant roles in market price determination, were overemphasized, leading to an inefficient supply chain. Meanwhile, government’s position through the Indonesia Logistics Bureau (BULOG) is assumed to be vulnerable in the control of direct supply from farmers or collectors. Based on this study, intense comprehension of rice supply chain was achieved, with further provision of collaborative strategies towards promoting the balance of demand and supply.

Tingginya permintaan lobster laut di pasar internasional maupun nasional serta harga jualnya yang tinggi membuat lobster menjadi salah satu komoditas ekspor potensial Indonesia. Karakteristik produk yang bersifat musiman membuat persediaan lobster tidak selalu bisa memenuhi permintaan pasar. Harga terbentuk berbasis pasar sehingga pemasok utama lobster dalam hal ini adalah nelayan, tidak dapat berpartisipasi dalam penentuan harga. Penyusunan strategi rantai pasok yang didasarkan pada hasil analisis struktur biaya logistik pada masing-masing rantai pasok perlu dilakukan untuk mencapai efisiensi. Metode yang digunakan adalah in-depth interview. Data dianalisis dengan model perhitungan biaya berbasis aktivitas untuk mengkaji besarnya biaya yang dikeluarkan tiap pelaku dan sebagai dasar perhitungan marjin keuntungan. Biaya terbesar terdapat pada aktivitas pengadaan (66,34%) yang sebagian besar ditanggung nelayan. Keuntungan terbesar diperoleh pemilik kapal (876,56%). Kondisi ini mengindikasikan adanya inefisiensi rantai pasok sehingga diperlukan strategi efisiensi, sedangkan ketidakseimbangan antara persediaan dan permintaan dapat diminimalisir dengan strategi responsif.

Fresh milk in Boyolali Regency is currently unable to meet the demand of the processing industry because the quantity is limited and the quality is below the standard. The large number of activities at each tier and the long supply chain flow for fresh milk have the potential to cause a decrease in quality and quantity, making it vulnerable to risk. Therefore, this research aimed to analyze risk management in supply chain and provide mitigation proposals. Data were collected by in-depth interviews with 51 respondents using purposive and snowball sampling techniques. The variables examined include supply chain flow of fresh milk, risks at each tier, causes and impacts of risks, as well as likelihood, severity, and capacity to manage risk. Data processing used ISO 31000:2018 and the Rapid Agricultural Supply Chain Risk Assessment (RapAgRisk) method to assess risk vulnerability. The results showed that in Boyolali Regency, fresh milk supply chain consists of four tiers, namely farmers, as well as milk couriers, collectors, and processors, comprising processing industry and street vendors. Mitigation proposals were given for nine risks in the categories of high, moderate, and low vulnerability. These risks include high animal feed prices, low forage availability, cows being attacked by foot and mouth disease (FMD), adulteration of fresh milk, the amount of fresh milk received by couriers and collectors fluctuating, rejection, sudden demand, and excess stock of fresh milk. Subsequently, risk mitigation proposals were provided to maintain quality and increase fresh milk production.
